drm/amdgpu: rework resume handling for display (v2)

2024-12-14T18:54:54+00:00

commit 73dae652dcac776296890da215ee7dec357a1032 upstream. Split resume into a 3rd step to handle displays when DCC is enabled on DCN 4.0.1. Move display after the buffer funcs have been re-enabled so that the GPU will do the move and properly set the DCC metadata for DCN. v2: fix fence irq resume ordering Reviewed-by: Christian König Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org # 6.11.x Signed-off-by: Greg Kroah-Hartman

drm/amdgpu: skip amdgpu_device_cache_pci_state under sriov

2024-12-14T18:54:43+00:00

[ Upstream commit afe260df55ac280cd56306248cb6d8a6b0db095c ] Under sriov, host driver will save and restore vf pci cfg space during reset. And during device init, under sriov, pci_restore_state happens after fullaccess released, and it can have race condition with mmio protection enable from host side leading to missing interrupts. So skip amdgpu_device_cache_pci_state for sriov. Signed-off-by: Victor Zhao Acked-by: Lijo Lazar Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin

Both of these threads access registers through the VF RLCG interface during VF Full Access. Add a lock around this interface to prevent race conditions between these threads.

drm/amdgpu: Check if NBIO funcs are NULL in amdgpu_device_baco_exit

[ Upstream commit 0cdb3f9740844b9d95ca413e3fcff11f81223ecf ] The special case for VM passthrough doesn't check adev->nbio.funcs before dereferencing it. If GPUs that don't have an NBIO block are passed through, this leads to a NULL pointer dereference on startup.

commit 03c6284df179de3a4a6e0684764b1c71d2a405e2 upstream. This patch causes the following iounmap erorr and calltrace iounmap: bad address 00000000d0b3631f The original patch was unjustified because amdgpu_device_fini_sw() will always cleanup the rmmio mapping.
