This can be useful for drivers in a kld that contain multiple new-bus drivers as part of one logical device driver. A typical case would be to use SI_ORDER_LAST for the "main" driver to ensure that any other "helper" drivers are registered and available before the "main" driver attempts to attach.

SVN rev 224069 on 2011-07-15 21:08:58Z by jhb Respect the BIOS/firmware's notion of acceptable address ranges for PCI resource allocation on x86 platforms: - Add a new helper API that Host-PCI bridge drivers can use to restrict resource allocation requests to a set of address ranges for different resource types. - For the ACPI Host-PCI bridge driver, use Producer address range resources in _CRS to enumerate valid address ranges for a given Host-PCI bridge. This can be disabled by including "hostres" in the debug.acpi.disabled tunable. - For the MPTable Host-PCI bridge driver, use entries in the extended MPTable to determine the valid address ranges for a given Host-PCI bridge. This required adding code to parse extended table entries. Similar to the new PCI-PCI bridge driver, these changes are only enabled if the NEW_PCIB kernel option is enabled (which is enabled by default on amd64 and i386). Approved by: re (kib)

This is primarily intended as a way to allow devices that use multiple interrupts (e.g. MSI) to meaningfully distinguish the various interrupt handlers. - Add a new BUS_DESCRIBE_INTR() method to the bus interface to associate a description with an active interrupt handler setup by BUS_SETUP_INTR. It has a default method (bus_generic_describe_intr()) which simply passes the request up to the parent device. - Add a bus_describe_intr() wrapper around BUS_DESCRIBE_INTR() that supports printf(9) style formatting using var args. - Reserve MAXCOMLEN bytes in the intr_handler structure to hold the name of an interrupt handler and copy the name passed to intr_event_add_handler() into that buffer instead of just saving the pointer to the name. - Add a new intr_event_describe_handler() which appends a description string to an interrupt handler's name. - Implement support for interrupt descriptions on amd64, i386, and sparc64 by having the nexus(4) driver supply a custom bus_describe_intr method that invokes a new intr_describe() MD routine which in turn looks up the associated interrupt event and invokes intr_event_describe_handler().

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 196037 on 2009-08-02 14:28:40Z by attilio
Make the newbus subsystem Giant free by adding the new newbus sxlock.
The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.
For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.
Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

SVN rev 193833 on 2009-06-09 14:26:23Z by jhb Add support for multiple passes of the device tree during the boot-time probe. The current device order is unchanged. This commit just adds the infrastructure and ABI changes so that it is easier to merge later changes into 8.x. - Driver attachments now have an associated pass level. Attachments are not allowed to probe or attach to drivers until the system-wide pass level is >= the attachment's pass level. By default driver attachments use the "last" pass level (BUS_PASS_DEFAULT). Driver's that wish to probe during an earlier pass use EARLY_DRIVER_MODULE() instead of DRIVER_MODULE() which accepts the pass level as an additional parameter. - A new method BUS_NEW_PASS has been added to the bus interface. This method is invoked when the system-wide pass level is changed to kick off a rescan of the device tree so that drivers that have just been made "eligible" can probe and attach. - The bus_generic_new_pass() function provides a default implementation of BUS_NEW_PASS(). It first allows drivers that were just made eligible for this pass to identify new child devices. Then it propogates the rescan to child devices that already have an attached driver by invoking their BUS_NEW_PASS() method. It also reprobes devices without a driver. - BUS_PROBE_NOMATCH() is only invoked for devices that do not have an attached driver after being scanned during the final pass. - The bus_set_pass() function is used during boot to raise the pass level. Currently it is only called once during root_bus_configure() to raise the pass level to BUS_PASS_DEFAULT. This has the effect of probing all devices in a single pass identical to previous behavior.

add a newbus method for obtaining the bus's bus_dma_tag_t... This is required by arches like sparc64 (not yet implemented) and sun4v where there are seperate IOMMU's for each PCI bus... For all other arches, it will end up returning NULL, which makes it a no-op... Convert a few drivers (the ones we've been working w/ on sun4v) to the new convection... Eventually all drivers will need to replace the parent tag of NULL, w/ bus_get_dma_tag(dev), though dev is usually different for each driver, and will require hand inspection...

If they prove to be too slow, we may be able to make rman non-opaque to
mitigate it. This should help porting drivers from -current into
-stable.

Add convenience macros for bus_space usage that doesn't require specification of bus tag+handle. Instead of bus_space_write_1(sc->tag, sc->handle, ...) this macros offer bus_write_1(sc->resource, ...) The name+argument transformation is constant and the the macros are generated (by hand) by the script in tools/bus_macro.sh.

Add two convenience functions for device drivers: bus_alloc_resources() and bus_free_resources(). These functions take a list of resources and handle them all in one go. A flag makes it possible to mark a resource as optional. A typical device driver can save 10-30 lines of code by using these. Usage examples will follow RSN. MFC: A good idea, eventually.

Use STAILQ in preference to SLIST for the resources. Insert new resources last in the list rather than first. This makes the resouces print in the 4.x order rather than the 5.x order (eg fdc0 at 0x3f0-0x3f5,0x3f7 is 4.x, but 0x3f7,0x3f0-0x3f5 is 5.x). This also means that the pci code will once again print the resources in BAR ascending order.

* Add multiple inheritance to kobj. Each class can have zero or more base classes and if a method is not found in a given class, its base classes are searched (in the order they were declared). This search is recursive, i.e. a method may be define in a base class of a base class. * Change the kobj method lookup algorithm to one which is SMP-safe. This relies only on the constraint that an observer of a sequence of writes of pointer-sized values will see exactly one of those values, not a mixture of two or more values. This assumption holds for all processors which FreeBSD supports. * Add locking to kobj class initialisation. * Add a simpler form of 'inheritance' for devclasses. Each devclass can have a parent devclass. Searches for drivers continue up the chain of devclasses until either a matching driver is found or a devclass is reached which has no parent. This can allow, for instance, pci drivers to match cardbus devices (assuming that cardbus declares pci as its parent devclass). * Increment __FreeBSD_version. This preserves the driver API entirely except for one minor feature used by the ISA compatibility shims. A workaround for ISA compatibility will be committed separately. The kobj and newbus ABI has changed - all modules must be recompiled.

* Factor out the object system from new-bus so that it can be used by non-device code. * Re-implement the method dispatch to improve efficiency. The new system takes about 40ns for a method dispatch on a 300Mhz PII which is only 10ns slower than a direct function call on the same hardware. This changes the new-bus ABI slightly so make sure you re-compile any driver modules which you use.

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

Remove the 'ivars' arguement to device_add_child() and device_add_child_ordered(). 'ivars' may now be set using the device_set_ivars() function. This makes it easier for us to change how arbitrary data structures are associated with a device_t. Eventually we won't be modifying device_t to add additional pointers for ivars, softc data etc. Despite my best efforts I've probably forgotten something so let me know if this breaks anything. I've been running with this change for months and its been quite involved actually isolating all the changes from the rest of the local changes in my tree. Reviewed by: peter, dfr

Zap DEV_DRIVER_MODULE(). The New world order is that drivers create their dev nodes with make_dev() in a devfs-compatable way by supplying names. This doesn't fit into a compile-time scheme like DEV_DRIVER_MODULE, especially since the cdevsw[] array's days are numbered.

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.

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.

Add one method to the BUS interface, BUS_CHILD_DETACHED() which is called after the child has been detached to allow the bus to clean up any memory which it allocated on behalf of the child. I also fixed a bug which corrupted the list of drivers in a devclass if a driver was added to more than one devclass.

Major changes to the generic device framework for FreeBSD/alpha: * Eliminate bus_t and make it possible for all devices to have attached children. * Support dynamically extendable interfaces for drivers to replace both the function pointers in driver_t and bus_ops_t (which has been removed entirely. Two system defined interfaces have been defined, 'device' which is mandatory for all devices and 'bus' which is recommended for all devices which support attached children. * In addition, the alpha port defines two simple interfaces 'clock' for attaching various real time clocks to the system and 'mcclock' for the many different variations of mc146818 clocks which can be attached to different alpha platforms. This eliminates two more function pointer tables in favour of the generic method dispatch system provided by the device framework. Future device interfaces may include: * cdev and bdev interfaces for devfs to use in replacement for specfs and the fixed interfaces bdevsw and cdevsw. * scsi interface to replace struct scsi_adapter (not sure how this works in CAM but I imagine there is something similar there). * various tailored interfaces for different bus types such as pci, isa, pccard etc.
