Actually, I think it's correct. When I merged the baco patch, I
accidentally dropped the navi checks. E.g.,
@@ -245,8 +245,9 @@ static void gmc_v10_0_flush_gpu_tlb(struct
amdgpu_device *adev,
mutex_lock(&adev->mman.gtt_window_lock);
gmc_v10_0_flush_vm_hub(adev, vmid, AMDGPU_MMHUB, 0);
- if (!adev->mman.buffer_funcs_enabled || !adev->ib_pool_ready ||
- adev->asic_type != CHIP_NAVI10) {
+ if (!adev->mman.buffer_funcs_enabled ||
+ !adev->ib_pool_ready ||
+ adev->in_gpu_reset) {
gmc_v10_0_flush_vm_hub(adev, vmid, AMDGPU_GFXHUB, 0);
mutex_unlock(&adev->mman.gtt_window_lock);
return;
I think it should have been
adev->asic_type != CHIP_NAVI10 && adev->asic_type != CHIP_NAVI14 &&
adev->asic_type != CHIP_NAVI12
