drm/amd/amdgpu: fixing read wrong pf2vf data in SRIOV

2022-01-18T23:00:58Z

[Why] This fixes 892deb48269c ("drm/amdgpu: Separate vf2pf work item init from virt data exchange"). we should read pf2vf data based at mman.fw_vram_usage_va after gmc sw_init. commit 892deb48269c breaks this logic. [How] calling amdgpu_virt_exchange_data in amdgpu_virt_init_data_exchange to set the right base in the right sequence. v2: call amdgpu_virt_init_data_exchange after gmc sw_init to make data exchange workqueue run v3: clean up the code logic v4: add some comment and make the code more readable Fixes: 892deb48269c ("drm/amdgpu: Separate vf2pf work item init from virt data exchange") Signed-off-by: Jingwen Chen Reviewed-by: Horace Chen Signed-off-by: Alex Deucher

drm/amdgpu: do not pass ttm_resource_manager to vram_mgr

2022-01-11T20:44:26Z

Do not allow exported amdgpu_vram_mgr_*() to accept any ttm_resource_manager pointer. Also there is no need to force other module to call a ttm function just to eventually call vram_mgr functions. v2: pass adev's vram_mgr instead of adev Reviewed-by: Christian König Signed-off-by: Nirmoy Das Signed-off-by: Alex Deucher

drm/amdgpu: Separate vf2pf work item init from virt data exchange

2021-12-16T19:08:20Z

We want to be able to call virt data exchange conditionally after gmc sw init to reserve bad pages as early as possible. Since this is a conditional call, we will need to call it again unconditionally later in the init sequence. Refactor the data exchange function so it can be called multiple times without re-initializing the work item. v2: Cleaned up the code. Kept the original call to init_exchange_data() inside early init to initialize the work item, afterwards call exchange_data() when needed.
