[PATCH V3] drm/amdgpu/display: Enable DC_FP for LoongArch

LoongArch now provides kernel_fpu_begin() and kernel_fpu_end() that are used like the x86 counterparts in commit 2b3bd32ea3a22ea2d ("LoongArch: Provide kernel fpu functions"), so we can enable DC_FP on LoongArch for supporting more DCN devices. Signed-off-by: WANG Xuerui Signed-off-

[PATCH] drm/amdgpu: Fix GPU TLB update error when PAGE_SIZE > AMDGPU_PAGE_SIZE

From: Yi Li When PAGE_SIZE is larger than AMDGPU_PAGE_SIZE, the number of GPU TLB entries which need to update in amdgpu_map_buffer() should be multiplied by AMDGPU_GPU_PAGES_IN_CPU_PAGE (PAGE_SIZE / AMDGPU_PAGE_SIZE). Signed-off-by: Yi Li Signed-off-by: Huacai Chen --- drivers/gpu/drm/amd

[PATCH 1/2] drm/radeon: Don't use WC for VRAM if !RADEON_GEM_GTT_WC

Though RADEON_GEM_GTT_WC is initially used for GTT, but this flag is bound to drm_arch_can_wc_memory(), and if arch doesn't support WC, then VRAM should not use WC. Signed-off-by: Huacai Chen --- drivers/gpu/drm/radeon/radeon_object.c | 14 ++ 1 file changed, 10 insertions(+), 4
