For AGP to work unmapped access must cover VRAM & AGP as
AGP is treated like VRAM by the GPU (ie physical address).
This patch properly setup the virtual memory system aperture
to cover AGP if AGP is enabled. It seems that there is memory
corruption after resume when using AGP (RV770 seems unaffected
thought). Version 2 just fix merge issue with updated AGP
fallback patch.

When GPU acceleration is not working with AGP try to fallback to non
AGP GART (either PCI or PCIE GART). This should make KMS failure on
AGP less painfull. We still need to find out what is wrong when AGP
fails but at least user have a lot of more chances to get a working
configuration with acceleration. This patch also cleanup R600/RV770
fallback path so they use same code as others asics. Version 2
factorize agp disabling logic to avoid code duplication and bugs.

The previous patches had some unwanted side effects, I've fixed
the lack of 32bpp working, and fixed up 16bpp so it should also work.
this also adds the interface to allow the driver to set a preferred
console depth so for example low memory rn50 can set it to 8bpp.
It also catches 24bpp on cards that can't do it and forces 32bpp.
Tested on r100/r600/i945.

0x07". But On some boxes it will print the following message many times in

"Surround View" is an option in the system bios that
enables the AMD IGP chip in conjunction with a
discrete AMD card. However, since the IGP vbios is
part of the system bios it is not accessible via the
rom bar or the legacy vga location. When "Surround View"
is enabled in the system bios, the system bios puts a
copy of the IGP vbios image at the start of vram.
This patch adds support for reading the vbios image out
of vram on IGP cards.

We were calling reset unconditionaly in the startup path
this is bad we need to call GPU reset for a good reason
as after reset the GPU is in unknown states. To avoid any
more bad things to happen we now also unconditionaly
reinitialize the GPU after reset. This patch fix few issues
reported by different people regarding KMS & R6XX/RV7XX hw.

This split write back buffer handling into 3 functions,
wb_fini for cleanup, wb_enable/wb_disable for enabling/disabling
write back used for suspend/resume. This should fix
potential issue of letting the write back active before
suspending. We need to allocate memory in wb_enable because
we can only allocate once GART is running.

New init path allow to simply asic initialization and make easier
to trace what happen on each different asic. We are removing most
callback. Do a massive RS600 register cleanup to clarify RS600

Also cleanup register specific to RS400/RS480. This patch also fix
legacy VGA register used to disable VGA access we were programming
wrong register. Now we should properly disable VGA on r100 up to
rs400 asics. Note that RS400/RS480 resume is broken, it hangs the
computer while reprogramming dynamic clock, doesn't work either
without that patch. We need to spend more time investigating this
issue. Version 2 of the patch remove dead code that was left
commented out in the previous version. Version 3 correct the

commit 537a1bf059fa312355696fa6db80726e655e7f17

fbdev: add mutex for fb_mmap locking
In which a mutex was added when changing smem_start and smem_len fields,
so the mutex inside the fb_mmap() call is actually used.
The problem was that set_fb_fix, which modifies the above 2 fields,
was called before and after registering the framebuffer,
which when used before registration, lead to a failed attempt to
use an uninitialized mutex.
Solution: Don't use mutex before framebuffer registration.

This patch enabled the ethoc to allocate system memory as buffer
when there is no dedicated buffer memory.
Some hardware designs may not have dedicated buffer memory such as
on chip or off chip SRAM. In this case, only one memory resource is
supplied in the platform data instead of two. Then a DMA buffer can
be allocated from system memory and used for the transfer.

The packet buffer is allocated at 4 bytes boundary, but the IP header
length and version bits is located at byte 14. These bit fields access
as 32 bits word and caused exception on processors that do not support

The pointer address in buffer descriptors is physical address. The
pointer that processor used to access packet is virtual address.
Though the higher bits of pointer address used by the MAC may be
truncated to zero in special case, it is not always true in larger
designs.

It should be max() instead of min(). Use 1/4 of available
descriptors for tx, and there should be at least 2 tx
descriptors.

in update_rx_stats() the RX_OVERLEN bit is set twice, replace it by RX_RUNT.
in au1000_rx() the RX_MISSED_FRAME bit was tested a few lines earlier already

Not all pasemi mac interfaces can have a phy attached.
For example, XAUI has no phy and phydev is NULL for it.
In this case ethtool get settings causes kernel crash.
Fix it by returning -EOPNOTSUPP if there's no PHY attached.

Felix Radensky noted that chip resets were generating stack trace dumps.
This is because the driver is attempting to acquire the mdio bus mutex
while holding the tp->lock spinlock. The fix is to change the code such
that every phy access takes the tp->lock spinlock instead.
