From: Christian König <christian.koenig@xxxxxxx> The fragment bits work differently for Vega10 compared to previous generations. Increase the fragment size to 2MB for now to better handle that. v2: handle the hardware setup as well Signed-off-by: Christian König <christian.koenig at amd.com> --- drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c | 5 +++-- drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c | 5 +++-- drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h | 4 +++- drivers/gpu/drm/amd/amdgpu/gfxhub_v1_0.c | 4 +++- drivers/gpu/drm/amd/amdgpu/mmhub_v1_0.c | 4 +++- 5 files changed, 15 insertions(+), 7 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c index 7a8da32..fc77844 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c @@ -588,8 +588,9 @@ static int amdgpu_info_ioctl(struct drm_device *dev, void *data, struct drm_file dev_info.virtual_address_offset = AMDGPU_VA_RESERVED_SIZE; dev_info.virtual_address_max = (uint64_t)adev->vm_manager.max_pfn * AMDGPU_GPU_PAGE_SIZE; dev_info.virtual_address_alignment = max((int)PAGE_SIZE, AMDGPU_GPU_PAGE_SIZE); - dev_info.pte_fragment_size = (1 << AMDGPU_LOG2_PAGES_PER_FRAG) * - AMDGPU_GPU_PAGE_SIZE; + dev_info.pte_fragment_size = + (1 << AMDGPU_LOG2_PAGES_PER_FRAG(adev)) * + AMDGPU_GPU_PAGE_SIZE; dev_info.gart_page_size = AMDGPU_GPU_PAGE_SIZE; dev_info.cu_active_number = adev->gfx.cu_info.number; diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c index 55d1c7f..a3dbebe 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c @@ -1381,8 +1381,9 @@ static int amdgpu_vm_frag_ptes(struct amdgpu_pte_update_params *params, */ /* SI and newer are optimized for 64KB */ - uint64_t frag_flags = AMDGPU_PTE_FRAG(AMDGPU_LOG2_PAGES_PER_FRAG); - uint64_t frag_align = 1 << AMDGPU_LOG2_PAGES_PER_FRAG; + unsigned pages_per_frag = AMDGPU_LOG2_PAGES_PER_FRAG(params->adev); + uint64_t frag_flags = AMDGPU_PTE_FRAG(pages_per_frag); + uint64_t frag_align = 1 << pages_per_frag; uint64_t frag_start = ALIGN(start, frag_align); uint64_t frag_end = end & ~(frag_align - 1); diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h b/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h index 3441ec5..c4f5d1f 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h @@ -51,7 +51,9 @@ struct amdgpu_bo_list_entry; #define AMDGPU_VM_PTB_ALIGN_SIZE 32768 /* LOG2 number of continuous pages for the fragment field */ -#define AMDGPU_LOG2_PAGES_PER_FRAG 4 +#define AMDGPU_LOG2_PAGES_PER_FRAG(adev) \ + ((adev)->asic_type < CHIP_VEGA10 ? 4 : \ + (adev)->vm_manager.block_size) #define AMDGPU_PTE_VALID (1ULL << 0) #define AMDGPU_PTE_SYSTEM (1ULL << 1) diff --git a/drivers/gpu/drm/amd/amdgpu/gfxhub_v1_0.c b/drivers/gpu/drm/amd/amdgpu/gfxhub_v1_0.c index 008ad3d..408723e 100644 --- a/drivers/gpu/drm/amd/amdgpu/gfxhub_v1_0.c +++ b/drivers/gpu/drm/amd/amdgpu/gfxhub_v1_0.c @@ -129,7 +129,7 @@ static void gfxhub_v1_0_init_cache_regs(struct amdgpu_device *adev) /* Setup L2 cache */ tmp = RREG32_SOC15(GC, 0, mmVM_L2_CNTL); tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, ENABLE_L2_CACHE, 1); - tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, ENABLE_L2_FRAGMENT_PROCESSING, 0); + tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, ENABLE_L2_FRAGMENT_PROCESSING, 1); /* XXX for emulation, Refer to closed source code.*/ tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, L2_PDE0_CACHE_TAG_GENERATION_MODE, 0); @@ -144,6 +144,8 @@ static void gfxhub_v1_0_init_cache_regs(struct amdgpu_device *adev) WREG32_SOC15(GC, 0, mmVM_L2_CNTL2, tmp); tmp = mmVM_L2_CNTL3_DEFAULT; + tmp = REG_SET_FIELD(tmp, VM_L2_CNTL3, BANK_SELECT, 12); + tmp = REG_SET_FIELD(tmp, VM_L2_CNTL3, L2_CACHE_BIGK_FRAGMENT_SIZE, 9); WREG32_SOC15(GC, 0, mmVM_L2_CNTL3, tmp); tmp = mmVM_L2_CNTL4_DEFAULT; diff --git a/drivers/gpu/drm/amd/amdgpu/mmhub_v1_0.c b/drivers/gpu/drm/amd/amdgpu/mmhub_v1_0.c index 96f1628..ad8def3 100644 --- a/drivers/gpu/drm/amd/amdgpu/mmhub_v1_0.c +++ b/drivers/gpu/drm/amd/amdgpu/mmhub_v1_0.c @@ -143,7 +143,7 @@ static void mmhub_v1_0_init_cache_regs(struct amdgpu_device *adev) /* Setup L2 cache */ tmp = RREG32_SOC15(MMHUB, 0, mmVM_L2_CNTL); tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, ENABLE_L2_CACHE, 1); - tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, ENABLE_L2_FRAGMENT_PROCESSING, 0); + tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, ENABLE_L2_FRAGMENT_PROCESSING, 1); /* XXX for emulation, Refer to closed source code.*/ tmp = REG_SET_FIELD(tmp, VM_L2_CNTL, L2_PDE0_CACHE_TAG_GENERATION_MODE, 0); @@ -158,6 +158,8 @@ static void mmhub_v1_0_init_cache_regs(struct amdgpu_device *adev) WREG32_SOC15(MMHUB, 0, mmVM_L2_CNTL2, tmp); tmp = mmVM_L2_CNTL3_DEFAULT; + tmp = REG_SET_FIELD(tmp, VM_L2_CNTL3, BANK_SELECT, 12); + tmp = REG_SET_FIELD(tmp, VM_L2_CNTL3, L2_CACHE_BIGK_FRAGMENT_SIZE, 9); WREG32_SOC15(MMHUB, 0, mmVM_L2_CNTL3, tmp); tmp = mmVM_L2_CNTL4_DEFAULT; -- 2.7.4
