SVN rev 217044 on 2011-01-06 04:12:29Z by nwhitehorn Import support for the Sony Playstation 3 using the OtherOS feature available on firmwares 3.15 and earlier. Caveats: Support for the internal SATA controller is currently missing, as is support for framebuffer resolutions other than 720x480. These deficiencies will be remedied soon. Special thanks to Peter Grehan for providing the hardware that made this port possible, and thanks to Geoff Levand of Sony Computer Entertainment for advice on the LV1 hypervisor.

SVN rev 213904 on 2010-10-15 20:08:16Z by andreast Add three new drivers for fan control and temperature reading on the PowerMac7,2. - The fcu driver lets us read and write the fan RPMs for all fans in the PowerMac7,2. This driver is PowerMac specific. - The ds1775 is a driver to read the temperature for the drive bay sensor. - The max6690 is another driver to read temperatures. Here it is used to read the inlet, the backside and the U3 heatsink temperature. An additional driver, the ad7417, will follow later. Thanks to nwhitehorn for guiding me through this driver development. Approved by: nwhitehorn (mentor)

Redefine bus_space_tag_t on PowerPC from a 32-bit integral to a pointer to struct bus_space. The structure contains function pointers that do the actual bus space access. The reason for this change is that previously all bus space accesses were little endian (i.e. had an explicit byte-swap for multi-byte accesses), because all busses on Macs are little endian. The upcoming support for Book E, and in particular the E500 core, requires support for big-endian busses because all embedded peripherals are in the native byte-order. With this change, there's no distinction between I/O port space and memory mapped I/O. PowerPC doesn't have I/O port space. Busses assign tags based on the byte-order only. For that purpose, two global structures exist (bs_be_tag and bs_le_tag), of which the address can be taken to get a valid tag. Obtained from: Juniper, Semihalf

Rename OEA to AIM. The former means nothing as it applies to all processors (it's the PowerPC Operating Environment Architecture). AIM designates the processors made by the Apple-IBM-Motorola alliance and those we typically support. While here, remove the NetBSD option IPKDB. It's not an option used by us. Also, PPC_HAVE_FPU is not used by us either. Remove that too. Obtained from: Juniper, Semihalf

o Revert the part of if_gem.c rev. 1.35 which added a call to gem_stop()
to gem_attach() as the former access softc members not yet initialized
at that time and gem_reset() actually is enough to stop the chip. [1]
o Revise the use of gem_bitwait(); add bus_barrier() calls before calling
gem_bitwait() to ensure the respective bit has been written before we
starting polling on it and poll for the right bits to change, f.e. even
though we only reset RX we have to actually wait for both GEM_RESET_RX
and GEM_RESET_TX to clear. Add some additional gem_bitwait() calls in
places we've been missing them according to the GEM documentation.
Along with this some excessive DELAYs, which probably only were added
because of bugs in gem_bitwait() and its use in the first place, as
well as as have of an gem_bitwait() reimplementation in gem_reset_tx()
were removed.
o Add gem_reset_rxdma() and use it to deal with GEM_MAC_RX_OVERFLOW errors
more gracefully as unlike gem_init_locked() it resets the RX DMA engine
only, causing no link loss and the FIFOs not to be cleared. Also use it
deal with GEM_INTR_RX_TAG_ERR errors, with previously were unhandled.
This was based on information obtained from the Linux GEM and OpenSolaris
ERI drivers.
o Turn on workarounds for silicon bugs in the Apple GMAC variants.
This was based on information obtained from the Darwin GMAC and Linux GEM
drivers.
o Turn on "infinite" (i.e. maximum 31 * 64 bytes in length) DMA bursts.
This greatly improves especially RX performance.
o Optimize the RX path, this consists of:
- kicking the receiver as soon as we've a spare descriptor in gem_rint()
again instead of just once after all the ready ones have been handled;
- kicking the receiver the right way, i.e. as outlined in the GEM
documentation in batches of 4 and by pointing it to the descriptor
after the last valid one;
- calling gem_rint() before gem_tint() in gem_intr() as gem_tint() may
take quite a while;
- doubling the size of the RX ring to 256 descriptors.
Overall the RX performance of a GEM in a 1GHz Sun Fire V210 was improved
from ~100Mbit/s to ~850Mbit/s.
o In gem_add_rxbuf() don't assign the newly allocated mbuf to rxs_mbuf
before calling bus_dmamap_load_mbuf_sg(), if bus_dmamap_load_mbuf_sg()
fails we'll free the newly allocated mbuf, unable to recycle the
previous one but a NULL pointer dereference instead.
o In gem_init_locked() honor the return value of gem_meminit().
o Simplify gem_ringsize() and dont' return garbage in the default case.
Based on OpenBSD.
o Don't turn on MAC control, MIF and PCS interrupts unless GEM_DEBUG is
defined as we don't need/use these interrupts for operation.
o In gem_start_locked() sync the DMA maps of the descriptor rings before
every kick of the transmitter and not just once after enqueuing all
packets as the NIC might instantly start transmitting after we kicked
it the first time.
o Keep state of the link state and use it to enable or disable the MAC
in gem_mii_statchg() accordingly as well as to return early from
gem_start_locked() in case the link is down. [3]
o Initialize the maximum frame size to a sane value.
o In gem_mii_statchg() enable carrier extension if appropriate.
o Increment if_ierrors in case of an GEM_MAC_RX_OVERFLOW error and in
gem_eint(). [3]
o Handle IFF_ALLMULTI correctly; don't set it if we've turned promiscuous
group mode on and don't clear the flag if we've disabled promiscuous
group mode (these were mostly NOPs though). [2]
o Let gem_eint() also report GEM_INTR_PERR errors.
o Move setting sc_variant from gem_pci_probe() to gem_pci_attach() as
device probe methods are not supposed to touch the softc.
o Collapse sc_inited and sc_pci into bits for sc_flags.
o Add CTASSERTs ensuring that GEM_NRXDESC and GEM_NTXDESC are set to
legal values.
o Correctly set up for 802.3x flow control, though #ifdef out the code
that actually enables it as this needs more testing and mainly a proper
framework to support it.
o Correct and add some conversions from hard-coded functions names to
__func__ which were borked or forgotten in if_gem.c rev. 1.42.
o Use PCIR_BAR instead of a homegrown macro.
o Replace sc_enaddr[6] with sc_enaddr[ETHER_ADDR_LEN].
o In gem_pci_attach() in case attaching fails release the resources in
the opposite order they were allocated.
o Make gem_reset() static to if_gem.c as it's not needed outside that
module.
o Remove the GEM_GIGABIT flag and the associated code; GEM_GIGABIT was
never set and the associated code was in the wrong place.
o Remove sc_mif_config; it was only used to cache the contents of the
respective register within gem_attach().
o Remove the #ifdef'ed out NetBSD/OpenBSD code for establishing a suspend
hook as it will never be used on FreeBSD.
o Also probe Apple Intrepid 2 GMAC and Apple Shasta GMAC, add support for
Apple K2 GMAC. Based on OpenBSD.
o Add support for Sun GBE/P cards, or in other words actually add support
for cards based on GEM to gem(4). This mainly consists of adding support
for the TBI of these chips. Along with this the PHY selection code was
rewritten to hardcode the PHY number for certain configurations as for
example the PHY of the on-board ERI of Blade 1000 shows up twice causing
no link as the second incarnation is isolated.
These changes were ported from OpenBSD with some additional improvements
and modulo some bugs.
o Add code to if_gem_pci.c allowing to read the MAC-address from the VPD on
systems without Open Firmware.
This is an improved version of my variant of the respective code in
if_hme_pci.c
o Now that gem(4) is MI enable it for all archs.

Add missing SC_NO_MODE_CHANGE option. Disable it in the powerpc NOTES though, as ofw_syscons(4) doesn't properly interface with syscons(4) regarding loading the font specified with SC_DFLT_FONT, causing a kernel with both options SC_OFWFB and SC_NO_MODE_CHANGE to not link.

Remove sio(4) and related options from MI files to amd64, i386 and pc98 MD files. Remove nodevice and nooption lines specific to sio(4) from ia64, powerpc and sparc64 NOTES. There were no such lines for arm yet. sio(4) is usable on less than half the platforms, not counting a future mips platform. Its presence in MI files is therefore increasingly becoming a burden.
