The non-volatile -qualifier prevents these cache lines from being distinguished from -those loaded through the private aperture. - -Use MTYPE_NC (1) instead on both Gfx7 and Gfx8. This allows the -compiler to use the BUFFER_WBINVL1_VOL instruction and is a precursor -to automatic per-dispatch scalar/vector L1 volatile invalidation. - -Change-Id: Ic366945bfa50034935adf42009ea70cb1fce99c3 -Signed-off-by: Jay Cornwall <Jay.Cornwall@amd.com> ---- - drivers/gpu/drm/amd/amdkfd/cik_regs.h | 3 ++- - drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_vi.c | 4 ++-- - 2 files changed, 4 insertions(+), 3 deletions(-) - -diff --git a/drivers/gpu/drm/amd/amdkfd/cik_regs.h b/drivers/gpu/drm/amd/amdkfd/cik_regs.h -index 607fc5c..8c707dc 100644 ---- a/drivers/gpu/drm/amd/amdkfd/cik_regs.h -+++ b/drivers/gpu/drm/amd/amdkfd/cik_regs.h -@@ -55,7 +55,8 @@ - #define APE1_MTYPE(x) ((x) << 7) - - /* valid for both DEFAULT_MTYPE and APE1_MTYPE */ --#define MTYPE_CACHED 0 -+#define MTYPE_CACHED_NV 0 -+#define MTYPE_CACHED 1 - #define MTYPE_NONCACHED 3 - - -diff --git a/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_vi.c b/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_vi.c -index abd71c6..2629143 100644 ---- a/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_vi.c -+++ b/drivers/gpu/drm/amd/amdkfd/kfd_device_queue_manager_vi.c -@@ -142,11 +142,11 @@ static bool set_cache_memory_policy_vi_tonga(struct device_queue_manager *dqm, - - default_mtype = (default_policy == cache_policy_coherent) ? - MTYPE_UC : -- MTYPE_NC_NV; -+ MTYPE_NC; - - ape1_mtype = (alternate_policy == cache_policy_coherent) ? - MTYPE_UC : -- MTYPE_NC_NV; -+ MTYPE_NC; - - qpd->sh_mem_config = - SH_MEM_ALIGNMENT_MODE_UNALIGNED << --- -2.7.4 - |
