drm/amdgpu: Don't default to DC support for Kaveri and older

2018-06-19T17:43:53+00:00

We've had a number of users report failures to detect and light up display with DC with LVDS and VGA. These connector types are not currently supported with DC. I'd like to add support but unfortunately don't have a system with LVDS or VGA available. In order not to cause regressions we should probably fallback to the non-DC driver for ASICs that support VGA and LVDS. These ASICs are: * Bonaire * Kabini * Kaveri * Mullins ASIC support can always be force enabled with amdgpu.dc=1 v2: Keep Hawaii on DC v3: Added Mullins to the list Cc: stable@vger.kernel.org Signed-off-by: Harry Wentland Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: fix CG enabling hang with gfxoff enabled

2018-06-13T18:45:21+00:00

After defer the execution of clockgating enabling, at that time, gfx already enter into "off" state. Howerver, clockgating enabling will use MMIO to access the gfx registers, then get the gfx hung. So here we should move the gfx powergating and gfxoff enabling behavior at the end of initialization behind clockgating.

Remove calls to suspend/resume atomic helpers from amdgpu_device_gpu_recover. (v2)

2018-05-24T04:51:20+00:00

First of all it's already being called from the display code from amd_ip_funcs.suspend/resume hooks. Second of all, the place in amdgpu_device_gpu_recover it's being called is wrong for GPU stalls since it is called BEFORE we cancel and force completion of all in flight jobs which were not yet processed. So, as Bas pointed in the ticket we will try to wait for fence in amdgpu_pm_compute_clocks but the pipe is hanged so we end up in deadlock. v2: remove unused variable Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106500 Signed-off-by: Andrey Grodzovsky Reviewed-by: Harry Wentland Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: For sriov reset, move IB test into exclusive mode

2018-05-15T18:44:06+00:00

When put the IB test out of exclusive mode, and do sriov reset, the IB test will randomly fail. As out of exclusive mode it uses kiq to do read and write registers, but as it has world switch, the kiq read and write time will be random, sometimes it will beyond the MAX_KIQ_REG_WAIT and then the read or write register will fail, which will result the IB test fail.
