2017-12-04drm/amdgpu: change redundant init logs to debug levelpding1-4/+4
When this VF stays in exclusive mode for long, other VFs will be impacted. The redundant messages causes exclusive mode timeout when they're redirected. That is a normal use case for cloud service to redirect guest log to virtual serial port.

2017-10-31drm/radeon: fix atombios on big endianRoman Kapl1-20/+18
The function for byteswapping the data send to/from atombios was buggy for num_bytes not divisible by four. The function must be aware of the fact that after byte-swapping the u32 units, valid bytes might end up after the num_bytes boundary. This patch was tested on kernel 3.12 and allowed us to sucesfully use DisplayPort on and Radeon SI card. Namely it fixed the link training and EDID readout. The function is patched both in radeon and amd drivers, since the functions and the fixes are identical.

2017-10-09drm/amdgpu: Reserve shared memory on VRAM for SR-IOVHorace Chen1-1/+17
SR-IOV need to reserve a piece of shared VRAM at the exact place to exchange data betweem PF and VF. The start address and size of the shared mem are passed to guest through VBIOS structure VRAM_UsageByFirmware. VRAM_UsageByFirmware is a general feature in VBIOS, it indicates that VBIOS need to reserve a piece of memory on the VRAM. Because the mem address is specified. Reserve it early in amdgpu_ttm_init to make sure that it can monoplize the space.

2017-04-04drm/amdgpu: Read vram width from integrated system info tableHarry Wentland1-0/+29
On KB, KV, CZ we should read the vram width from integrated system table, if we can. The NOOFCHAN in MC_SHARED_CHMAP is not accurate. With this change we can enable two 4k displays on CZ again. This use case was broken sometime in January when we started looking at vram_width for bandwidth calculations instead of hardcoding this value. v2: Return 0 if integrated system info table is not available.
