This patch series re-work a few i915 functions to use drm_clflush_virt_range instead of calling clflush or clflushopt directly. This will prevent errors when building for non-x86 architectures. v2: s/PAGE_SIZE/sizeof(value) for Re-work intel_write_status_page and added more patches to convert additional clflush/clflushopt to use drm_clflush*. (Michael Cheng) v3: Drop invalidate_csb_entries and directly invoke drm_clflush_virt_ran v4: Remove extra memory barriers v5: s/cache_clflush_range/drm_clflush_virt_range v6: Fix up "Drop invalidate_csb_entries" to use correct parameters. Also added in arm64 support for drm_clflush_virt_range. v7: Re-order patches, and use correct macro for dcache flush for arm64. v8: Remove ifdef for asm/cacheflush. v9: Rebased v10: Replaced asm/cacheflush with linux/cacheflush Michael Cheng (6): drm: Add arch arm64 for drm_clflush_virt_range drm/i915/gt: Re-work intel_write_status_page drm/i915/gt: Drop invalidate_csb_entries drm/i915/gt: Re-work reset_csb drm/i915/: Re-work clflush_write32 drm/i915/gt: replace cache_clflush_range drivers/gpu/drm/drm_cache.c | 6 ++++++ .../gpu/drm/i915/gem/i915_gem_execbuffer.c | 8 +++----- drivers/gpu/drm/i915/gt/gen8_ppgtt.c | 12 +++++------ drivers/gpu/drm/i915/gt/intel_engine.h | 13 ++++-------- .../drm/i915/gt/intel_execlists_submission.c | 20 +++++++------------ drivers/gpu/drm/i915/gt/intel_gtt.c | 2 +- drivers/gpu/drm/i915/gt/intel_ppgtt.c | 2 +- .../gpu/drm/i915/gt/uc/intel_guc_submission.c | 2 +- 8 files changed, 29 insertions(+), 36 deletions(-) -- 2.25.1
