drm/amdgpu: there is no vbios fb on devices with no display hw (v2)

2022-11-15T18:24:40+00:00

If we enable virtual display functionality on parts with no display hardware we can end up trying to check for and reserve the vbios FB area on devices where it doesn't exist. Check if display hardware is actually present on the hardware before trying to reserve the memory. v2: move the check into common code Acked-by: Evan Quan Signed-off-by: Alex Deucher

Revert "drm/amdgpu: add debugfs amdgpu_reset_level"

2022-10-19T02:08:25+00:00

This reverts commit 5bd8d53f6fa53eab5433698d1362dae2aa53c1cc. This commit breaks the reset logic for aldebaran, revert it for now. Will move the mask inside the reset handler.

drm/amdgpu: add gang submit backend v2

2022-09-20T16:40:32+00:00

Allows submitting jobs as gang which needs to run on multiple engines at the same time. Basic idea is that we have a global gang submit fence representing when the gang leader is finally pushed to run on the hardware last. Jobs submitted as gang are never re-submitted in case of a GPU reset since this won't work and will just deadlock the hardware immediately again. v2: fix logic inversion, improve documentation, fix rcu Signed-off-by: Christian König Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: reduce reset time

2022-08-16T22:14:31+00:00

In multi container use case, reset time is important, so skip ring tests and cp halt wait during ip suspending for reset as they are going to fail and cost more time on reset v2: add a hang flag to indicate the reset comes from a job timeout, skip ring test and cp halt wait in this case v3: move hang flag to adev Signed-off-by: Victor Zhao Acked-by: Andrey Grodzovsky Signed-off-by: Alex Deucher

drm/amdgpu: add debugfs amdgpu_reset_level

2022-08-16T22:14:31+00:00

Introduce amdgpu_reset_level debugfs in order to help debug and test specific type of reset. Also helps blocking unwanted type of resets. By default, mode2 reset will not be enabled v2: make this debugfs in adev and use debugfs_create_u32 Signed-off-by: Victor Zhao Acked-by: Andrey Grodzovsky Signed-off-by: Alex Deucher

drm/amdgpu: Increase tlb flush timeout for sriov

2022-08-16T22:08:01+00:00

[Why] During multi-vf executing benchmark (Luxmark) observed kiq error timeout. It happenes because all of VFs do the tlb invalidation at the same time. Although each VF has the invalidate register set, from hardware side the invalidate requests are queue to execute. [How] In case of 12 VF increase timeout on 12*100ms Signed-off-by: Dusica Milinkovic Acked-by: Shaoyun Liu Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: Fix the incomplete product number

2022-07-28T20:05:14+00:00

The comments say that the product number is a 16-digit HEX string so the buffer needs to be at least 17 characters to hold the NUL terminator. Expand the buffer size to 20 to avoid the alignment issues. The comment:Product number should only be 16 characters. Any more,and something could be wrong. Cap it at 16 to be safe Signed-off-by: Roy Sun Reviewed-by: André Almeida Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amd/display: Add visualconfirm module parameter

[Why] Being able to configure visual confirm at boot or in cmdline is helpful when debugging. [How] Add a module parameter to configure DC visual confirm, which works the same way as the equivalent debugfs entry. Signed-off-by: Leo Li Reviewed-by: Rodrigo Siqueira Signed-off-by: Alex Deucher

drm/amdgpu: support reset flag set for gpu reset

Move reset_context out of gpu recover function to make it configurable for different reset purpose. For the reset way of call gpu_recovery sysfs, force to use full reset method. Otherwise, try soft reset by default if the related ASIC supportted, if soft reset failed, will use full reset. Signed-off-by: Likun Gao Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher
