From 179d2c0e0bcf96fc40107882ccab909af8c89853 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Tue, 2 Mar 2010 15:34:17 -0800 Subject: intel: Use drm_intel_bo_alloc_tiled for region allocs. This moves the logic for how to align pitches, heights, and sizes of objects to one central location. Fixes rendering with texture tiling on i915. Note that current libdrm is required for the change for I915_TILING_NONE pitch alignment. --- src/mesa/drivers/dri/intel/intel_regions.c | 39 +++++++++--------------------- 1 file changed, 11 insertions(+), 28 deletions(-) (limited to 'src') diff --git a/src/mesa/drivers/dri/intel/intel_regions.c b/src/mesa/drivers/dri/intel/intel_regions.c index f63d3a40825..e3c0635e5ba 100644 --- a/src/mesa/drivers/dri/intel/intel_regions.c +++ b/src/mesa/drivers/dri/intel/intel_regions.c @@ -180,36 +180,19 @@ intel_region_alloc(struct intel_context *intel, { dri_bo *buffer; struct intel_region *region; + unsigned long flags = 0; + unsigned long aligned_pitch; - /* If we're tiled, our allocations are in 8 or 32-row blocks, so - * failure to align our height means that we won't allocate enough pages. - * - * If we're untiled, we still have to align to 2 rows high because the - * data port accesses 2x2 blocks even if the bottom row isn't to be - * rendered, so failure to align means we could walk off the end of the - * GTT and fault. - */ - if (tiling == I915_TILING_X) - height = ALIGN(height, 8); - else if (tiling == I915_TILING_Y) - height = ALIGN(height, 32); - else - height = ALIGN(height, 2); - - /* If we're untiled, we have to align to 2 rows high because the - * data port accesses 2x2 blocks even if the bottom row isn't to be - * rendered, so failure to align means we could walk off the end of the - * GTT and fault. + if (expect_accelerated_upload) + flags |= BO_ALLOC_FOR_RENDER; + + buffer = drm_intel_bo_alloc_tiled(intel->bufmgr, "region", + width, height, cpp, + &tiling, &aligned_pitch, flags); + /* We've already chosen a pitch as part of miptree layout.
