amd/amdgpu: use kmalloc_array to replace kmalloc with multiply

2020-11-24T17:04:39Z

Fix check_patch.pl warning: WARNING: Prefer kmalloc_array over kmalloc with multiply +bps = kmalloc(align_space * sizeof((*data)->bps), GFP_KERNEL); WARNING: Prefer kmalloc_array over kmalloc with multiply +bps_bo = kmalloc(align_space * sizeof((*data)->bps_bo), GFP_KERNEL); kmalloc_array has multiply overflow check, which will be safer.

drm/amdgpu/virt: fix handling of the atomic flag

2020-11-06T09:31:26Z

Use the per device drm driver feature flags rather than the global one. This way we can make the drm driver struct const.

drm/amdgpu: Implement new guest side VF2PF message transaction (v2)

2020-09-25T21:03:22Z

- Refactor the driver code to use amdgpu_virt_read_pf2vf_data and amdgpu_virt_write_vf2pf_data instead of writing all code in one function (which is the old amdgpu_virt_init_data_exchange) - Adding a new transaction method for VF2PF message between host and guest driver. Guest side will periodically update VF2PF message in the framebuffer. In the new header, we include guest ucode information, guest framebuffer usage, and engine usage - Clean up the old macros since they will cause compile error if the new transaction method is used v2: squash in build fix Signed-off-by: Bokun Zhang Reviewed-by: Monk Liu Signed-off-by: Alex Deucher

drm/amdgpu: revert "fix system hang issue during GPU reset"

2020-08-14T20:22:40Z

The whole approach wasn't thought through till the end. We already had a reset lock like this in the past and it caused the same problems like this one. Completely revert the patch for now and add individual trylock protection to the hardware access functions as necessary. This reverts commit df9c8d1aa278c435c30a69b8f2418b4a52fcb929.
