[PATCH] Revert "drm/amdgpu: remove TOPDOWN flags when allocating VRAM in large bar system"

This reverts commit c105518679b6e87232874ffc989ec403bee59664. This patch disables the TOPDOWN flag for APU and few dGPU cards which has the VRAM size equal to the BAR size. When we enable the TOPDOWN flag, we get the free blocks at the highest available memory region and we don't split the lower

Radeon Driver Crash

Hello, I just filed a bug for the Radeon driver crashing: https://bugzilla.kernel.org/show_bug.cgi?id=217464 It looks similar to this bug (https://bugzilla.kernel.org/show_bug.cgi?id=198669) because they are both locking up the GPU and the page fault address is at the same page offset of 0xffc, wh

[PATCH] drm/amdgpu: Rearrange WREG32 operations in gfxhub_v2_1.c

In gfxhub_v2_1_setup_vmid_config(), the GCVM_CONTEXT1_CNTL reg is written before related GCVM_CONTEXT1_PAGE_TABLE_START_ADDR and GCVM_CONTEXT1_PAGE_TABLE_END_ADDR regs are written, which may cause undefined behavior. This patch rearranges WREG32 operations in gfxhub_v2_1_setup_vmid_config(), so th
