drm/amdgpu: reduce the time of reading VBIOS

2017-07-25T20:37:39+00:00

VRAM is usually marked write combined, so change ioremap mode from
noncache to write combine for reading vbios from VRAM.

This will reduce cost time of reading vbios from 188ms to 8ms.

drm/amd/amdgpu: post card if there is real hw resetting performed

2017-02-17T21:12:58+00:00

Check whether we need to post rather than whether the asic is
posted.  There are some cases (e.g., GPU reset or resume from
hibernate) where we need to force post even if the asic has
been posted.

2017-01-27T17:20:42+00:00

The vfct table can contain multiple vbios images if the
platform contains multiple GPUs. Noticed by netkas on
phoronix forums.  This patch fixes those platforms.

drm/amdgpu: Refine the way to get atom bios

2017-01-27T16:12:45+00:00

There are several ways to check out a ATOMBIOS. In previous codes, try
a new way to fetch out vbios/rom, until current vbios/rom is started with
0x55aa, then check if this vbios is ATOMBIOS. Now, try a new way to fetch
out vbios until all flags of ATOMBIOS are verified.

drm/amdgpu: Remove checking for atombios

2017-01-27T16:12:39+00:00

This is a left over from radeon, amdgpu doesn't support any
non-atombios parts and amdgpu_device_init would bail if the
check for atombios failed anyway.
