SVN rev 223674 on 2011-06-29 15:58:26Z by jhb MFC 221393,222930: Reimplement how PCI-PCI bridges manage their I/O windows. Previously the driver would verify that requests for child devices were confined to any existing I/O windows, but the driver relied on the firmware to initialize the windows and would never grow the windows for new requests. Now the driver actively manages the I/O windows. This is implemented by allocating a bus resource for each I/O window from the parent PCI bus and suballocating that resource to child devices. The suballocations are managed by creating an rman for each I/O window. The suballocated resources are mapped by passing the bus_activate_resource() call up to the parent PCI bus. Windows are grown when needed by using bus_adjust_resource() to adjust the resource allocated from the parent PCI bus. If the adjust request succeeds, the window is adjusted and the suballocation request for the child device is retried. When growing a window, the rman_first_free_region() and rman_last_free_region() routines are used to determine if the front or end of the existing I/O window is free. From using that, the smallest ranges that need to be added to either the front or back of the window are computed. The driver will first try to grow the window in whichever direction requires the smallest growth first followed by the other direction if that fails. Subtractive bridges will first attempt to satisfy requests for child resources from I/O windows (including attempts to grow the windows). If that fails, the request is passed up to the parent PCI bus directly however. The PCI-PCI bridge driver will try to use firmware-assigned ranges for child BARs first and only allocate a "fresh" range if that specific range cannot be accommodated in the I/O window. This allows systems where the firmware assigns resources during boot but later wipes the I/O windows (some ACPI BIOSen are known to do this) to "rediscover" the original I/O window ranges. The ACPI Host-PCI bridge driver has been adjusted to correctly honor hw.acpi.host_mem_start and the I/O port equivalent when a PCI-PCI bridge makes a wildcard request for an I/O window range. The new PCI-PCI bridge driver is only enabled if the NEW_PCIB kernel option is enabled.

SVN rev 220195 on 2011-03-31 13:22:12Z by jhb Explicitly track the state of all known BARs for each PCI device. The PCI bus driver will now remember the size of a BAR obtained during the initial bus scan and use that size when doing lazy resource allocation rather than resizing the BAR. The bus driver will now also report unallocated BARs to userland for display by 'pciconf -lb'. Psuedo-resources that are not BARs (such as the implicit I/O port resources for master/slave ATA controllers) will no longer be listed as BARs in 'pciconf -lb'. During resume, BARs are restored from their new saved state instead of having the raw registers saved and restored across resume. This also fixes restoring BARs at unusual loactions if said BAR has been allocated by a driver. Add a constant for the offset of the ROM BIOS BAR in PCI-PCI bridges and properly handle ROM BIOS BARs in PCI-PCI bridges. The PCI bus now also properly handles the lack of a ROM BIOS BAR in a PCI-Cardbus bridge. Tested by: jkim

PCI now uses the term "extended capabilities" to refer to the new set of capability structures starting at offset 0x100 in config space for PCI-express devices. For now both function names will still work. I will merge this to older branches to ease driver portability, but 9.0 will ship with a new pci_find_extcap() function that locates extended capabilities instead. Reviewed by: imp MFC after: 1 week

SVN rev 200315 on 2009-12-09 21:52:53Z by jhb For some buses, devices may have active resources assigned even though they are not allocated by the device driver. These resources should still appear allocated from the system's perspective so that their assigned ranges are not reused by other resource requests. The PCI bus driver has used a hack to effect this for a while now where it uses rman_set_device() to assign devices to the PCI bus when they are first encountered and later assigns them to the actual device when a driver allocates a BAR. A few downsides of this approach is that it results in somewhat confusing devinfo -r output as well as not being very easily portable to other bus drivers. This commit adds generic support for "reserved" resources to the resource list API used by many bus drivers to manage the resources of child devices. A resource may be reserved via resource_list_reserve(). This will allocate the resource from the bus' parent without activating it. resource_list_alloc() recognizes an attempt to allocate a reserved resource. When this happens it activates the resource (if requested) and then returns the reserved resource. Similarly, when a reserved resource is released via resource_list_release(), it is deactivated (if it is active) and the resource is then marked reserved again, but is left allocated from the bus' parent. To completely remove a reserved resource, a bus driver may use resource_list_unreserve(). A bus driver may use resource_list_busy() to determine if a reserved resource is allocated by a child device or if it can be unreserved. The PCI bus driver has been changed to use this framework instead of abusing rman_set_device() to keep track of reserved vs allocated resources.

SVN rev 191795 on 2009-05-04 20:35:59Z by jhb MFC: Various fixes to the PCI resource allocation code: - Disabling decoding of BARs via the PCI command register before writing to the BARs to size them. - Don't free resources decoded by a BAR when the device driver releases a BAR. Instead, the PCI bus now owns unclaimed BARs and gives them to drivers on demand. When a driver releases a BAR, the PCI bus reclaims it and leaves the resource range allocated. This also prevents drivers from allocating the same resource multiple times. - Move the activation of BARs by enabling decoding in the PCI command register into bus_activate_resource() so that it always happens after the BAR is fully programmed. - Always read/write the full 64-bit value of 64-bit BARs. - Consolidate duplicated code for reading and sizing BARs and writing base address to BARs.

SVN rev 189306 on 2009-03-03 16:38:59Z by jhb Further refine the handling of resources for BARs in the PCI bus driver. A while back, Warner changed the PCI bus code to reserve resources when enumerating devices and simply give devices the previously allocated resources when they call bus_alloc_resource(). This ensures that address ranges being decoded by a BAR are always allocated in the nexus0 device (or whatever device the PCI bus gets its address space from) even if a device driver is not attached to the device. This patch extends this behavior further: - To let the PCI bus distinguish between a resource being allocated by a device driver vs. merely being allocated by the bus, use rman_set_device() to assign the device to the bus when it is owned by the bus and to the child device when it is allocated by the child device's driver. We can now prevent a device driver from allocating the same device twice. Doing so could result in odd things like allocating duplicate virtual memory to map the resource on some archs and leaking the original mapping. - When a PCI device driver releases a resource, don't pass the request all the way up the tree and release it in the nexus (or similar device) since the BAR is still active and decoding. Otherwise, another device could later allocate the same range even though it is still in use. Instead, deactivate the resource and assign it back to the PCI bus using rman_set_device(). - pci_delete_resource() will actually completely free a BAR including attemping to disable it. - Disable BAR decoding via the command register when sizing a BAR in pci_alloc_map() which is used to allocate resources for a BAR when the BIOS/firmware did not assign a usable resource range during boot. This mirrors an earlier fix to pci_add_map() which is used when to size BARs during boot. - Move the activation of I/O decoding in the PCI command register into pci_activate_resource() instead of doing it in pci_alloc_resource(). Previously we could actually enable decoding before a BAR was initialized via pci_alloc_map(). Glanced at by: bsdimp

SVN rev 181333 on 2008-08-05 18:24:41Z by jhb If the kernel fails to allocate resources for the initial value of a BAR for a PCI device during the boot-time probe of the parent PCI bus, then zero the BAR and clear the resource list entry for that BAR. This forces the PCI bus driver to request a valid resource range from the parent bridge driver when the device driver tries to allocate the BAR. Similarly, if the initial value of a BAR is a valid range but it is > 4GB and the current OS only has 32-bit longs, then do a full teardown of the initial value of the BAR to force a reallocation.

Relax the check for a PCI-express chipset by assuming the system is a PCI-express chipset (and thus has functional MSI) if there are any PCI-express devices in the system, not requiring a root port device. With PCI-X the chipset detection has to be very conservative because there are known systems with PCI-X devices that do not appear to have PCI-X chipsets. However, with PCI-express I'm not sure it is possible to have a PCI-express device in a system with a non-PCI-express chipset. If we assume that is the case then this change is valid. It is also required for at least some PCI-express systems that don't have any devices with a root port capability (some ICH9 systems). MFC after: 1 week Reported by: jfv

Make the PCI code aware of PCI domains (aka PCI segments) so we can support machines having multiple independently numbered PCI domains and don't support reenumeration without ambiguity amongst the devices as seen by the OS and represented by PCI location strings. This includes introducing a function pci_find_dbsf(9) which works like pci_find_bsf(9) but additionally takes a domain number argument and limiting pci_find_bsf(9) to only search devices in domain 0 (the only domain in single-domain systems). Bge(4) and ofw_pcibus(4) are changed to use pci_find_dbsf(9) instead of pci_find_bsf(9) in order to no longer report false positives when searching for siblings and dupe devices in the same domain respectively. Along with this change the sole host-PCI bridge driver converted to actually make use of PCI domain support is uninorth(4), the others continue to use domain 0 only for now and need to be converted as appropriate later on. Note that this means that the format of the location strings as used by pciconf(8) has been changed and that consumers of <sys/pciio.h> potentially need to be recompiled.

Revamp the MSI/MSI-X code a bit to achieve two main goals: - Simplify the amount of work that has be done for each architecture by pushing more of the truly MI code down into the PCI bus driver. - Don't bind MSI-X indicies to IRQs so that we can allow a driver to map multiple MSI-X messages into a single IRQ when handling a message shortage. The changes include: - Add a new pcib_if method: PCIB_MAP_MSI() which is called by the PCI bus to calculate the address and data values for a given MSI/MSI-X IRQ. The x86 nexus drivers map this into a call to a new 'msi_map()' function in msi.c that does the mapping. - Retire the pcib_if method PCIB_REMAP_MSIX() and remove the 'index' parameter from PCIB_ALLOC_MSIX(). MD code no longer has any knowledge of the MSI-X index for a given MSI-X IRQ. - The PCI bus driver now stores more MSI-X state in a child's ivars. Specifically, it now stores an array of IRQs (called "message vectors" in the code) that have associated address and data values, and a small virtual version of the MSI-X table that specifies the message vector that a given MSI-X table entry uses. Sparse mappings are permitted in the virtual table. - The PCI bus driver now configures the MSI and MSI-X address/data registers directly via custom bus_setup_intr() and bus_teardown_intr() methods. pci_setup_intr() invokes PCIB_MAP_MSI() to determine the address and data values for a given message as needed. The MD code no longer has to call back down into the PCI bus code to set these values from the nexus' bus_setup_intr() handler. - The PCI bus code provides a callout (pci_remap_msi_irq()) that the MD code can call to force the PCI bus to re-invoke PCIB_MAP_MSI() to get new values of the address and data fields for a given IRQ. The x86 MSI code uses this when an MSI IRQ is moved to a different CPU, requiring a new value of the 'address' field. - The x86 MSI psuedo-driver loses a lot of code, and in fact the separate MSI/MSI-X pseudo-PICs are collapsed down into a single MSI PIC driver since the only remaining diff between the two is a substring in a bootverbose printf. - The PCI bus driver will now restore MSI-X state (including programming entries in the MSI-X table) on device resume. - The interface for pci_remap_msix() has changed. Instead of accepting indices for the allocated vectors, it accepts a mini-virtual table (with a new length parameter). This table is an array of u_ints, where each value specifies which allocated message vector to use for the corresponding MSI-X message. A vector of 0 forces a message to not have an associated IRQ. The device may choose to only use some of the IRQs assigned, in which case the unused IRQs must be at the "end" and will be released back to the system. This allows a driver to use the same remap table for different shortage values. For example, if a driver wants 4 messages, it can use the same remap table (which only uses the first two messages) for the cases when it only gets 2 or 3 messages and in the latter case the PCI bus will release the 3rd IRQ back to the system.

The notable differences between this patch and what is in HEAD now are that pci_remap_msix() is not currently implemented in this patch (I need to change the API in HEAD, so I'm not going to MFC it until its API is stable) and MSI and MSI-X are not enabled by default. To enable MSI and MSI-X support, one must set the 'hw.pci.msi_enable' and/or 'hw.pci.msix_enable' loader tunables.

Adjust the global MSI blacklisting strategy so we don't have to explicitly blacklist a bunch of old chipsets. If a system contains a PCI-PCI bridge that supports PCI-X, assume the chipset supports PCI-X. If a system contains a PCI-express root port, assume the chipset supports PCI-express. If the chipset doesn't support either PCI-X or PCI-express, then blacklist it by default. We should now only need to explicitly blacklist PCI-X or PCI-express chipsets that don't properly handle MSI.

As VPD support still causes hard hangs on boot with some hardware, add a tunable allowing automatic parsing of VPD data to be disabled. The default is left as-is; if you are having problems with hard hangs at boot due to VPD, try setting hw.pci.enable_vpd=0. A proper architectural solution has been under discussion for some time, but this allows me to boot my test machines in the mean time. Submitted by: bz Head nod: jmg

Expand the MSI/MSI-X API to address some deficiencies in the MSI-X support.
- First off, device drivers really do need to know if they are allocating
MSI or MSI-X messages. MSI requires allocating powerof2() messages for
example where MSI-X does not. To address this, split out the MSI-X
support from pci_msi_count() and pci_alloc_msi() into new driver-visible
functions pci_msix_count() and pci_alloc_msix(). As a result,
pci_msi_count() now just returns a count of the max supported MSI
messages for the device, and pci_alloc_msi() only tries to allocate MSI
messages. To get a count of the max supported MSI-X messages, use
pci_msix_count(). To allocate MSI-X messages, use pci_alloc_msix().
pci_release_msi() still handles both MSI and MSI-X messages, however.
As a result of this change, drivers using the existing API will only
use MSI messages and will no longer try to use MSI-X messages.
- Because MSI-X allows for each message to have its own data and address
values (and thus does not require all of the messages to have their
MD vectors allocated as a group), some devices allow for "sparse" use
of MSI-X message slots. For example, if a device supports 8 messages
but the OS is only able to allocate 2 messages, the device may make the
best use of 2 IRQs if it enables the messages at slots 1 and 4 rather
than default of using the first N slots (or indicies) at 1 and 2. To
support this, add a new pci_remap_msix() function that a driver may call
after a successful pci_alloc_msix() (but before allocating any of the
SYS_RES_IRQ resources) to allow the allocated IRQ resources to be
assigned to different message indices. For example, from the earlier
example, after pci_alloc_msix() returned a value of 2, the driver would
call pci_remap_msix() passing in array of integers { 1, 4 } as the
new message indices to use. The rid's for the SYS_RES_IRQ resources
will always match the message indices. Thus, after the call to
pci_remap_msix() the driver would be able to access the first message
in slot 1 at SYS_RES_IRQ rid 1, and the second message at slot 4 at
SYS_RES_IRQ rid 4. Note that the message slots/indices are 1-based
rather than 0-based so that they will always correspond to the rid
values (SYS_RES_IRQ rid 0 is reserved for the legacy INTx interrupt).
To support this API, a new PCIB_REMAP_MSIX() method was added to the
pcib interface to change the message index for a single IRQ.

First cut at MI support for PCI Message Signalled Interrupts (MSI):
- Add 3 new functions to the pci_if interface along with suitable wrappers
to provide the device driver visible API:
- pci_alloc_msi(dev, int *count) backed by PCI_ALLOC_MSI(). '*count'
here is an in and out parameter. The driver stores the desired number
of messages in '*count' before calling the function. On success,
'*count' holds the number of messages allocated to the device. Also on
success, the driver can access the messages as SYS_RES_IRQ resources
starting at rid 1. Note that the legacy INTx interrupt resource will
not be available when using MSI. Note that this function will allocate
either MSI or MSI-X messages depending on the devices capabilities and
the 'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. Also note
that the driver should activate the memory resource that holds the
MSI-X table and pending bit array (PBA) before calling this function
if the device supports MSI-X.
- pci_release_msi(dev) backed by PCI_RELEASE_MSI(). This function
releases the messages allocated for this device. All of the
SYS_RES_IRQ resources need to be released for this function to succeed.
- pci_msi_count(dev) backed by PCI_MSI_COUNT(). This function returns
the maximum number of MSI or MSI-X messages supported by this device.
MSI-X is preferred if present, but this function will honor the
'hw.pci.enable_msix' and 'hw.pci.enable_msi' tunables. This function
should return the largest value that pci_alloc_msi() can return
(assuming the MD code is able to allocate sufficient backing resources
for all of the messages).
- Add default implementations for these 3 methods to the pci_driver generic
PCI bus driver. (The various other PCI bus drivers such as for ACPI and
OFW will inherit these default implementations.) This default
implementation depends on 4 new pcib_if methods that bubble up through
the PCI bridges to the MD code to allocate IRQ values and perform any
needed MD setup code needed:
- PCIB_ALLOC_MSI() attempts to allocate a group of MSI messages.
- PCIB_RELEASE_MSI() releases a group of MSI messages.
- PCIB_ALLOC_MSIX() attempts to allocate a single MSI-X message.
- PCIB_RELEASE_MSIX() releases a single MSI-X message.
- Add default implementations for these 4 methods that just pass the
request up to the parent bus's parent bridge driver and use the
default implementation in the various MI PCI bridge drivers.
- Add MI functions for use by MD code when managing MSI and MSI-X
interrupts:
- pci_enable_msi(dev, address, data) programs the MSI capability address
and data registers for a group of MSI messages
- pci_enable_msix(dev, index, address, data) initializes a single MSI-X
message in the MSI-X table
- pci_mask_msix(dev, index) masks a single MSI-X message
- pci_unmask_msix(dev, index) unmasks a single MSI-X message
- pci_pending_msix(dev, index) returns true if the specified MSI-X
message is currently pending
- Save the MSI capability address and data registers in the pci_cfgreg
block in a PCI devices ivars and restore the values when a device is
resumed. Note that the MSI-X table is not currently restored during
resume.
- Add constants for MSI-X register offsets and fields.
- Record interesting data about any MSI-X capability blocks we come
across in the pci_cfgreg block in the ivars for PCI devices.

More fully support 64-bit bars. Prior to this commit, we supported only those bars that had addresses assigned by the BIOS and where the bridges were properly programmed. Now even unprogrammed ones work. This was needed for sun4v. We still only implement up to 2GB memory ranges, even for 64-bit bars. PCI standards at least through 2.2 say that this is the max (or 1GB is, I only know it is < 32bits). o Always define pci_addr_t as uint64_t. A pci address is always 64-bits, but some hosts can't address all of them. o Preserve the upper half of the 64-bit word during resource probing. o Test to make sure that 64-bit values can fit in a u_long (true on some platforms, but not others). Don't use those that can't. o minor pedantry about data sizes. o Better bridge resource reporting in bootverbose case. o Minor formatting changes to cope with different data types on different platforms. Submitted by: jmg, with many changes by me to fully support 64-bit addresses.

Simplify the pager support in DDB. Allowing different db commands to install custom pager functions didn't actually happen in practice (they all just used the simple pager and passed in a local quit pointer). So, just hardcode the simple pager as the only pager and make it set a global db_pager_quit flag that db commands can check when the user hits 'q' (or a suitable variant) at the pager prompt. Also, now that it's easy to do so, enable paging by default for all ddb commands. Any command that wishes to honor the quit flag can do so by checking db_pager_quit. Note that the pager can also be effectively disabled by setting $lines to 0. Other fixes: - 'show idt' on i386 and pc98 now actually checks the quit flag and terminates early. - 'show intr' now actually checks the quit flag and terminates early.

Expose pci_add_resources to the outside world, add a 'force' flag to force allocation of unallocated BARs (cardbus uses this to preallocate everything). Add a prefetchmask to allow for busses that get prefetch hints to set them. Addjust pci_add_map and pci_ata_maps to take a new force flag which pci_add_resources will pass in. Implement 'force' in pci_add_map. Write new value of allocated resource into the bar, if the allocation succeeded (we should have done this before, but with the new force the bug was very obvious).

Add a new method PCI_FIND_EXTCAP() to the pci bus interface that is used to search for a specific extended capability. If the specified capability is found for the given device, then the function returns success and optionally returns the offset of that capability. If the capability is not found, the function returns an error.

MFp4: When doing lazy allocation, it turns out that we need to record the actual resource values we received from the system rather than the range we requested. Since we request a range starting at 0, we would record that number. Later, since this == 0, we'd allocate again. However, we wouldn't write the new resource into the BAR. This resulted in a resource leak as well as a BAR that couldn't access the resource at all since rman_get_start, et al, were wrong. MFC After: 1 week (assuming RELENG_6 is open for business)

Add a 1 microsecond delay in pci_add_children(), right before the read of the PCIR_HDRTYPE register. It's the value returned from this read access that determines whether or not we decide a device is present at the current slot index. For some reason that I can't adequately explain, this read fails on my machine when probing the USB controller on my machine (which happens a multifunction device at slot index 3 hung off the PCI-PCI bridge on the AMD8111 (bus index 1)). The read will return 0xFF even though it should return 0x80 to indicate the presence of a multifunction device. As near as I can tell, there's some timing issue involved with reading the 'dead' slot indexes 0 through 2 that causes the read of the actual device at slot 3 to fail. I tried a couple of different tricks to correct the problem (the patch to amd64/pci/pci_cfgreg.c fixes it for the amd64 arch), but adding this delay is the only thing that always allows the USB controllers to be correctly probed 100% of the time. Whatever the problem is, it's likely confined to the AMD8111 chipset. However, a simple 1us delay is fairly harmless and should have no side effects for other hardware. I consider this to be voodoo, but it's fairly benign voodoo and it makes my USB keyboard and mouse work again. Note that this is the second time that I've had to resort to a 1us delay to fix a PCI-related problem with this AMD8111/Opteron system (the first being a fix I made a while back to the NDISulator). It's possible the delay really belongs in the cfgreg code itself, or that pci_cfgreg needs some custom hackery for an errata in the 8111. (I checked but couldn't find any documented errata on AMD's site that could account for these problems.)

- Consolidate duplicated code for assigning interrupts to PCI devices via routing, etc. in a static pci_assign_interrupt() function. - Add a sledgehammer that allows the user to override the interrupt assignment of any PCI device via a tunable (e.g. "hw.pci0.7.INTB=5" would force any functions on the pci device in slot 7 of bus 0 that use B# to use IRQ 5). This should be used with great caution! Generally, if the interrupt routing in use provides specific tunables (such as hard-wiring the IRQ for a given $PIR or ACPI PCI link device), then those should be used instead. One instance where this tunable might be useful is if a box has an MPTable with duplicate entries for the same PCI device with different IRQs. MFC after: 1 week

The former defaults to 0 while the latter defaults to 1. When do_powerstate was set to 0, it broke suspend/resume for a lot of people as an unintended consequence.

Change the default of pci_do_powerstate to 0, per request from re@. The number of raid controllers that violate the WHQL seems to be growing in number and not isolated to old versions as previously thought. Though the numbers of these seen in the wild is still relatively small, they hang the system when parts of their devices are powered down. The one area that these parts appear often are in the higher end servers. As such, be conservative about powering down devices that have no driver attached by default. Until a better approach is proven in current, this is the prudent choice. Laptop users wishing the benefits of powering down devices with no drivers will now need to set hw.pci.do_powerstate=1 in their /boot/loader.conf file. Some users will have devices that will prevent this setting (hence the need to make it default 0). Approved by: re@ (scottl)

Change hw.pci.do_powerstate from a boolean to a range. 0 means the same as today: do no power management. 1 means be conservative about what you power down (any device class that has caused problems gets added here). 2 means be agressive about what gets powered down (any device class that's fundamental to the system is here). 3 means power them all down, reguardless. The default is 1. The effect in the default system is to add mass storage devices to the list that we don't power down. From all the pciconf -l lists that I've seen for the aac and amr issue, the bad device has been a mass storage device class. This is an attempt at a compromise between the very small number of systems that have extreme issues with powerdown, and the very large number of systems that gain real benefits from powerdown (I get about 20% more battery life when I attach a minimal set of drivers on my Sony). Hopefully it will strike the proper balance. MFC After: 3 days (before next beta)

Don't enable I/O or memory mode in a device's command register if the BAR we are processing has a base address of zero. Note that this will only change behavior for devices where all the BARs of a given type have a base address of 0 since we will enable the appropriate access when we encounter the first BAR with a base that is not 0. Specifically, this allows certain Toshiba laptops to no longer require 'hw.pci.enable_io_modes=0' to avoid hangs during boot.

It turns out that a lot of newer systems have 'base peripherals' on the PCI bus. We presently have no drivers for these devices, so they are powered down. This is undesirable behavior since it breaks the system when the base peripherals go away suddenly in the middle of boot. # if we ever get generic drivers for memory and/or base peripherals, then # we can remove the tests here.

Turn ACPI and PCI devices off or to a lower power state in suspend and
back on again in resume. Override the default of D3 with the value the
BIOS specifies in _SxD, if present. Skip serial devices (PNP05xx) since
they seem to hang when set to D3 and may require special driver support.
Also, skip non-type 0 PCI devices (i.e., bridges) since our we don't yet
save/restore their config space and that seems to be necessary.
If this gives you trouble with suspend/resume, you can disable the new
ACPI and PCI power behavior separately with these tunables & sysctls:

Setting the variable to 0 will effectively turn off paging. - Change db_putchar() to force out pending whitespace before outputting newlines and carriage returns so that one can rub out content on the current line via '\r \r' type strings. - Change the simple pager to rub out the --More-- prompt explicitly when the routine exits. - Add some aliases to the simple pager to make it more compatible with more(1): 'e' and 'j' do a single line.

Do not write to those config registers that are unambiguously defined in the various pci specifications as readonly. vendor, subvendor, device and subdevice are required to be loaded in hardware by some means that isn't the system BIOS or other system software (although some devices do have ways of accomplishing this). class and subclass are defined to be read-only in section 6.2.1 (v2.2). Apart from the status register, which we weren't touching, these are the only read-only registers I could find in the 2.2 spec. progif is also defined as being read-only in section 6.2.1. However, the PCI IDE programming document specifically states that some of the bits are read/write. Since we may have to restore registers before we have a driver attached, go ahead and restore this one byte when transitioning between D3 and D0. The PCI spec also says that writes to reserved and unimplemented registers must be completed normally. It makes no statements about writes to read-only registers, so be as conservative as possible, while covering the exception to the rule that is documented in a subpart of the standard.

Add a stopgap for the EBus breakage on sparc64 since the PCI code does resource pre-allocation. The problem is that the BARs of the EBus bridges contain the ranges for the resources for the EBus devices beyond the bridge. So when the EBus code tries to allocate the resource for an EBus device it's already allocated by the PCI code. To be removed again as soon as we have a proper solution in the EBus Code.

ata devices in legacy are special, and we must treat them as such. While I would have prefered to have a solution that didn't move knowledge of this into the pci layer. However, this is literally the only exception that's listed in the PCI standard to the usual way of decoding BARs. atapci devices in legacy mode now ignore the first 4 bars and hard code the values to the legacy ide values (well, for each of the controllers that are in legacy mode). The 5th bar is handled normally. Remove the zero bar handling. zero bars should be ignored at all other times, and since we handle that specially, we don't need the older workaround.

Some devices have what appear to be invalid BARs. They are invalid in the sense that any write to them reads back as a 0. This presents a problem to our resource allocation scheme. If we encounter such vars, the code now treats them as special, allowing any allocation against them to succeed. I've not seen anything in the standard to clearify what host software should do when it encounters these sorts of BARs. Also cleaned up some output while I'm here and add commmented out bootverbose lines until I'm ready to reduce the verbosity of boot messages. This gets a number of south bridges and ata controllers made mostly by VIA, AMD and nVidia working again. Thanks to Soren Schmidt for his help in coming up with this patch.

Initial landing of SMP support for FreeBSD/amd64. - This is heavily derived from John Baldwin's apic/pci cleanup on i386. - I have completely rewritten or drastically cleaned up some other parts.

I have a workaround in mind, but right now the Asus SK8N is broken. The Gigabyte K8NPro (nVidia based) is also mind-numbingly hosed. - Most of my testing has been with SCHED_ULE. SCHED_4BSD works. - the apic and acpi components are 'standard'. - If you have an nVidia nForce3-150 board, you are stuck with 'device atpic' in addition, because they somehow managed to forget to connect the 8254 timer to the apic, even though its in the same silicon! ARGH! This directly violates the ACPI spec.

Add a new PCI interface method, assign_interrupt, to determine the interrupt to be used for a device. This is intended solely for internal use of PCI bus implementations, and exists so that PCI bus drivers implementing special interrupt assignment methods which require additional work at the bus level to work right can be easily derived from the generic driver (or any other one) without resorting to hacks. It will be used in the sparc64 ofw_pcibus driver, which will be committed shortly. Make use of this method in the generic implementation, and add it to the method table of bus drivers derived from the PCI one. Reviewed by: imp, -hackers

- Adjust the comment about re-routing PCI interrupts to be less ia64-specific. - When trying to re-route interrupts, don't change cfg->intline if the re-route fails by returning an invalid vector. This fixes machines without any way of routing interrupts such as older PC's without a $PIR table. We do not currently write the new intline value back to the hardware, but we should. That will likely be added in a later commit.

Overhaul the ACPI PCI bridge driver a bit:
- Add an ACPI PCI-PCI bridge driver (the previous driver just handled
Host-PCI bridges) that is a PCI driver that is a subclass of the generic
PCI-PCI bridge driver. It overrides probe, attach, read_ivar, and
pci_route_interrupt.
- The probe routine only succeeds if our parent is an ACPI PCI bus which
we test for by seeing if we can read our ACPI_HANDLE as an ivar.
- The attach routine saves a copy of our handle and calls the new
acpi_pcib_attach_common() function described below.
- The read_ivar routine handles normal PCI-PCI bridge ivars and adds an
ivar to return the ACPI_HANDLE of the bus this bridge represents.
- The route_interrupt routine fetches the _PRT (PCI Interrupt Routing
Table) from the bridge device's softc and passes it off to
acpi_pcib_route_interrupt() to route the interrupt.
- Split the old ACPI Host-PCI bridge driver into two pieces. Part of
the attach routine and most of the route_interrupt routine remain in
acpi_pcib.c and are shared by both ACPI PCI bridge drivers.
- The attach routine verifies the PCI bridge is present, reads in
the _PRT for the bridge, and attaches the child PCI bus.
- The route_interrupt routine uses the passed in _PRT to route a PCI
interrupt.
The rest of the driver is the ACPI Host-PCI bridge specific bits that
live in acpi_pcib_acpi.c.
- We no longer duplicate pcib_maxslots but use it directly.
- The driver now uses the pcib devclass instead of its own devclass.
This means that PCI busses are now only children of pcib devices.
- Allow the ACPI_HANDLE for the child PCI bus to be read as an ivar
of the child bus.
- Fetch the _PRT for routing PCI interrupts directly from our softc
instead of walking the devclass to find ourself and then fetch our
own softc.
With this change and the new ACPI PCI bus driver, ACPI can now properly
route interrupts for devices behind PCI-PCI bridges. That is, the
Itanium2 with like 10 PCI busses can now boot ok and route all the PCI
interrupts. Hopefully this will also fix problems people are having with
CardBus bridges behind PCI-PCI bridges not properly routing interrupts
when ACPI is used.

Various changes to make it easier to subclass the PCI bus device. - Make the pci devclass a global variable. - Add child devices in pci_attach() instead of pci_probe(). Change pci_probe() to just check for a valid bus number from the associated bridge and return -1000 if successful. This allows subclasses of the PCI bus driver to override the generic driver. - Move the code to load the vendor data into its own public function. Really though, doing this at attach is just plain wrong. This should really be done in the module load routine instead. As a side effect, the 'busno' variable in pci_attach() is now no longer static (minor bug that was harmless so far.) - Change pci_add_children() to take an extra argument that is the size of the device info structure passed to pci_read_device() and make it public so subclasses of the PCI bus can call it in their attach routines. - Move the bits to attach a probed PCI child to a PCI bus into a global pci_add_child() function. This will allow subclasses that can detect a PCI device not found in the normal PCI probe to add those devices in their own attach routine. (I have seen this in the ACPI tree on my laptop for example.) As a side effect, change the static function pci_add_resources() to get the busno, slot, and func from the passed in dinfo structure instead of requiring them as function arguments.

Use the pci.c code wherever possible, rather than copying all the pci code into cardbus and s/pci/cardbus. This exposes a few pci_* functions that are now static. This work is similar to work Justin posted to the mobile list about a year or two ago, which I have neglected since then. This is a subset of his current work with the multiple inheritance newbus architecutre. When completed, that will eliminate the need for pci/pci_private.h. Similar work is needed for the cardbus_cis and pccard_cis code as well.

Some alphas leave garbage in the intline and leave the intr mapping to OS platform support routines that map slots/buses to intlines - Down in the alpha pci code, first try platform.pci_intr_route() and if it doesn't exist or returns garbage, just read the intline out of config space. tested on AS500 (garbage in intline) and UP1000 (PC-like, intline is valid) Note that a nice little hack like the APIC_IO section of pci_cfgregread() is not workable. This is because the calling interface for alpha_pci_route_interrupt() requires us to figure out the bus/slot/etc from a device_t. At pci_read_device() time, we don't have a device_t for the bus/slot/func in question.

Next round of PCI subsystem updates: - Break out the /dev/pci driver into a separate file. - Kill the COMPAT_OLDPCI support. - Make the EISA bridge attach a bit more like the old code; explicitly check for the existence of eisa0/isa0 and only attach if they don't already exist. Only make one bus_generic_attach() pass over the bridge, once both busses are attached. Note that the stupid Intel bridge's class is entirely unpredictable. - Add prototypes and re-layout the core PCI modules in line with current coding standards (not a major whitespace change, just moving the module data to the top of the file). - Remove redundant type-2 bridge support from the core PCI code; the PCI-CardBus code does this itself internally. Remove the now entirely redundant header-class-specific support, as well as the secondary and subordinate bus number fields. These are bridge attributes now. - Add support for PCI Extended Capabilities. - Add support for PCI Power Management. The interface currently allows a driver to query and set the power state of a device. - Add helper functions to allow drivers to enable/disable busmastering and the decoding of I/O and memory ranges. - Use PCI_SLOTMAX and PCI_FUNCMAX rather than magic numbers in some places. - Make the PCI-PCI bridge code a little more paranoid about valid I/O and memory decodes. - Add some more PCI register definitions for the command and status registers. Correct another bogus definition for type-1 bridges.

Next phase in the PCI subsystem cleanup. - Move PCI core code to dev/pci. - Split bridge code out into separate modules. - Remove the descriptive strings from the bridge drivers. If you want to know what a device is, use pciconf. Add support for broadly identifying devices based on class/subclass, and for parsing a preloaded device identification database so that if you want to waste the memory, you can identify *anything* we know about. - Remove machine-dependant code from the core PCI code. APIC interrupt mapping is performed by shadowing the intline register in machine- dependant code. - Bring interrupt routing support to the Alpha (although many platforms don't yet support routing or mapping interrupts entirely correctly). This resulted in spamming <sys/bus.h> into more places than it really should have gone. - Put sys/dev on the kernel/modules include path. This avoids having to change *all* the pci*.h includes.

If a base address register has been set up by the BIOS, but the relevant enable bit hasn't been set in the command register, set the bit and honour the register.

* Completely rewrite the alpha busspace to hide the implementation from the drivers. * Remove legacy inx/outx support from chipset and replace with macros which call busspace. * Rework pci config accesses to route through the pcib device instead of calling a MD function directly. With these changes it is possible to cleanly support machines which have more than one independantly numbered PCI busses. As a bonus, the new busspace implementation should be measurably faster than the old one.

Fixed the type of some ivar access functions. Ivars have type uintptr_t, not u_long. On i386's with 64-bit longs, returning u_longs indirectly in (more than) the space reserved for uintptr_t's tended to corrupt the previous frame pointer in the stack frame, so it was not easy to debug. The type mismatches are hidden by the bogus cast in DEVMETHOD().

Make the pci driver compat shim return a preference for probe rather than an "it's mine!" so that other newbus-aware drivers can bid for the device too. This should allow the sym driver to out-bid the ncr driver for devices it supports without having to modify ncr.c at all. ncr would then function as a catch-all.

Move the pretty printing of the description for USB controllers to pci_probe_nomatch, so it won't be in the way when loading USB as a module. The reason for them being there in the first place is that every motherboard comes with USB kit and this way it looks more pretty (peter). The real solution will be to define some method of detaching a driver after it has attached.

Backout part of the changes made in 1.111 For unknown devices the output will now be pci0: unknown card (vendor=0x109e, dev=0x0878) at 14.1 irq 19 instead of pci0: unknown card DD^0878 (vendor=0x109e, dev=0x0878) at 14.1 irq 19 Before this change, the code used to take the PCI vendor id and translate it into a three letter ASCII name. For PnP devices, the vendor id _does_ map to a nice ASCII name (eg Creative Labs PnP ID maps to "CTL", ESS PnP ID maps to "ESS") But there is no such mapping for PCI devices, as can be seen by the example above where the Brooktree PCI vendor ID maps to "DD^" The PCI Special Interest Group confirmed they do not have any mappings from vendor ID to ASCII.

Diskslice/label code not yet handled.
Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)
Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw
registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().

Alter the behavior of sys/kern/subr_bus.c:device_print_child() - device_print_child() either lets the BUS_PRINT_CHILD method produce the entire device announcement message or it prints "foo0: not found\n" Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on the previous behavior of device_print_child() (printing the "foo0: <FooDevice 1.1>" bit of the announce message.) Provide bus_print_child_header() and bus_print_child_footer() to actually print the output for bus_generic_print_child(). These functions should be used whenever possible (unless you can just use bus_generic_print_child()) The BUS_PRINT_CHILD method now returns int instead of void. Modify everything else that defines or uses a BUS_PRINT_CHILD method to comply with the above changes. - Devices are 'on' a bus, not 'at' it. - If a custom BUS_PRINT_CHILD method does the same thing as bus_generic_print_child(), use bus_generic_print_child() - Use device_get_nameunit() instead of both device_get_name() and device_get_unit() - All BUS_PRINT_CHILD methods return the number of characters output.

Implement the BUS_PROBE_NOMATCH method for the PCI bus. This function is called for each device for which no driver was found. Output is similar to the eisa_probe_nomatch() function but with the added benefit of displaying the assigned IRQ (since PCI gives us this information up front.) Output is like so: pci0: unknown card CPQ0508 (vendor=0x0e11, dev=0x0508) at 11.0 irq 9 pci0: unknown card DFZ0508 (vendor=0x10da, dev=0x0508) at 11.0 irq 9 pci0: unknown card DBL0508 (vendor=0x104c, dev=0x0508) at 11.0 irq 9 pci0: unknown card DDM0011 (vendor=0x108d, dev=0x0011) at 11.0 irq 9 I'm not happy with the 3 lines of macro cruft that got added but I consider it a temporary annoyance as those bits will be moved to some place where PCI, EISA and ISAPNP code will be able to use them. (Not surprisingly, this message is longer than the code in question.) Reviewed by: peter, dfr

On the new Meteor cards, the Philips SAA 7116 is connected to the PCI bus via an IBM PCI-PCI bridge (82351 or 82352 or 82353) The driver must identify if it is on a secondary PCI bus, which is created via the IBM PCI-PCI bridge. If it is, then it must initialise the IBM PCI-PCI bridge correctly. To do this, the following new functions are added. Because they use the pcici_t tag, they are considered 2.2 compatibility APIs pcici_t * pci_get_parent_from_tag(pcici_t tag); int pci_get_bus_from_tag(pcici_t tag); (The _from_tag suffix is used to prevent clashes with similarly named newbus PCI API functions) Submitted by: Anton Berezin <tobez@plab.ku.dk> Reviewed by: Doug Rabson <dfr@nlsystems.com> Reworked by: Me (roger)

Replace the pcidevice_set linker set based configuration mechanism for old style pci drivers with a simple one-line change to use a module that registers itself under new-bus and should in theory enable just about all of the pci drivers to be loadable (kldload and loader(8)) but without having the impact of converting the APIs yet. This also fixes the problem of having undefined variables when only new-style pci drivers are present.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

In the cyrix Cx5530, there are null (empty) Base address registers before the base register that controls Ultra-DMA, so we need to examine all possible base registers instead of just giving up at the first empty one. Also, looking at the source code to the BIOS, I see that they are also checking for 0xffffffff as an invalid value so do the same. Stefan may like to clean this up, but at least now I can find my PCI IDE registers.

Maintain a mapping from irq number to (ioapic number, int pin) tuple, and use this when masking/unmasking interrupts. Maintain a mapping from (iopaic number, int pin) tuple to irq number, and use this when configuring devices and programming the ioapics. Previous code assumed that irq number was equal to int pin number, and that the ioapic number was 0. Don't let an AP enter _cpu_switch before all local apics are initialized.

This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

Add two workarounds for broken MP tables: - Attempt to handle PCI devices where the interrupt is an ISA/EISA interrupt according to the mp table. - Attempt to handle multiple IO APIC pins connected to the same PCI or ISA/EISA interrupt source. Print a warning if this happens, since performance is suboptimal. This workaround is only used for PCI devices. With these two workarounds, the -SMP kernel is capable of running on my Asus P/I-P65UP5 motherboard when version 1.4 of the MP table is disabled.

The new PCIOCATTACHED ioctl on /dev/pci allows user-land programs to find out, whether a PCI device got a driver attached. The "pciconf" function has been extended to return that information for automatic PCI driver loading from /etc/rc.

The config register dump printed in the bootverbose case has been slightly rearranged.

Completely replace the PCI bus driver code to make it better reflect reality. There will be a new call interface, but for now the file pci_compat.c (which is to be deleted, after all drivers are converted) provides an emulation of the old PCI bus driver functions. The only change that might be visible to drivers is, that the type pcici_t (which had been meant to be just a handle, whose exact definition should not be relied on), has been converted into a pcicfgregs* . The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t and has been converted to just call the PCI drivers functions to access configuration space register, instead of inventing its own ... This code is by no means complete, but assumed to be fully operational, and brings the official code base more in line with my development code. A new generic device descriptor data type has to be agreed on. The PCI code will then use that data type to provide new functionality: 1) userconfig support 2) "wired" PCI devices 3) conflicts checking against ISA/EISA 4) maps will depend on the command register enable bits 5) PCI to Anything bridges can be defined as devices, and are probed like any "standard" PCI device. The following features are currently missing, but will be added back, soon: 1) unknown device probe message 2) suppression of "mirrored" devices caused by ancient, broken chip-sets This code relies on generic shared interrupt support just commited to kern_intr.c (plus the modifications of isa.c and isa_device.h).

Man the liferafts! Here comes the long awaited SMP -> -current merge! There are various options documented in i386/conf/LINT, there is more to come over the next few days. The kernel should run pretty much "as before" without the options to activate SMP mode. There are a handful of known "loose ends" that need to be fixed, but have been put off since the SMP kernel is in a moderately good condition at the moment. This commit is the result of the tinkering and testing over the last 14 months by many people. A special thanks to Steve Passe for implementing the APIC code!

Add preliminary support for the Orion PCI chip set. It is special in the way it attaches multiple PCI buses directly to the CPU, instead of having them hanging off from PCI to PCI bridges. This code is a hack, and will be obsoleted by the planned rework of the PCI code, which will change the dealing with PCI to PCI bridges and other special devices significantly. The patch also adds a kern_devconf entry for PCI bus 0 which is assumed to be a child of cpu0. The new PCI code will make it possible to hand out the kern_devconf structure to a pci device being attached, since this is (regretably, IMHO) required by a few ISA devices. Finally there are new PCI ids for some Intel chip set devices, which had already been known to 2.1.5R, but did not make it into -current. This closes "kern/1558: PCI probe seems to have lost a device in -current".

Fix logic bug in pci bridge code. For a PCI-PCI bridge, secondary should be <= than subordinate, not the other way around. They are both true if the bridge is not cascaded (i.e., twin-channel scsi/e-net adapters won't be affected by this bug), which is probably why it was unnoticed until today.

(This is required to simulate non-existant devices in my system for PCI bridge code tests.) - reorder some functions (put the main functions at the end). - correct off by one bug in the code dealing with unitialized PCI to PCI bridge chips. (Bug found by ASAMI Satoshi.) - print function number for multi-function devices.

Remove limit of port I/O addresses to 65K, since PCI specifies 32 bit port addresses (even though the PC architecture doesn't support them). Add code to limit the I/O map size based on the lowest set bit of the address. This cures the problem with the BT946C only having a 16 bit map register, in voiolation of the PCI specs, without giving up the general support of >65K port regions.

Decode configuration for the IDE part of the Triton chipset. This includes a hack in the probe code: the 82371FB is a multifuction device, but doesn't properly set the configuration bit which indicates this. So, we just hard-wire all 82371FBs as multifunction devices. This does not actually make the bus-master IDE stuff work, although if anyone wants to work on that, I have the databooks that tell how to use it.

Added a bit of missing functionality to make this work correctly on a wider variety of systems. Include the deivers from pci_intel.c in pci_config.c (I hope this is what was intended; my system works ok). Use pmap_mapdev(). Automatically map any large linear frame buffers or whatnot in VGA-style devices which ordinarily would not have their own drivers, and don't call not_supported() for them. (This shuts up complaints about my Matrox card.) Include the beginnings of what could eventually become dynamically-loadable PCI devices. Allow for the possibility of PCI devices simply providing a PCI veneer over an existing ISA device, and shut up about them, too. Make autoconfiguration text conform more to the style of other supported buses.
