From 5e15497452cf3e4d2fc76fdc6ed8113d0891b467 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 11 May 2011 13:14:16 +1000 Subject: [PATCH] r600g: delay mapping until first map request. (v2) Currently r600g always maps every bo, this is quite pointless as it wastes VM and on 32-bit with wine running VM space is quite useful. So with this patch we don't create the mappings until first use, without tiling enabled this probably won't make a major difference on its own, but with tiled staged uploads it should avoid keeping maps for most of the textures unnecessarily. v2: add bo data ptr check Signed-off-by: Dave Airlie --- src/gallium/winsys/r600/drm/r600_priv.h | 3 +++ src/gallium/winsys/r600/drm/radeon_bo.c | 7 +------ 2 files changed, 4 insertions(+), 6 deletions(-) diff --git a/src/gallium/winsys/r600/drm/r600_priv.h b/src/gallium/winsys/r600/drm/r600_priv.h index f8363f9..2ca122a 100644 --- a/src/gallium/winsys/r600/drm/r600_priv.h +++ b/src/gallium/winsys/r600/drm/r600_priv.h @@ -145,6 +145,7 @@ int radeon_bo_get_tiling_flags(struct radeon *radeon, int radeon_bo_get_name(struct radeon *radeon, struct radeon_bo *bo, uint32_t *name); +int radeon_bo_fixed_map(struct radeon *radeon, struct radeon_bo *bo); /* * r600_hw_context.c @@ -192,6 +193,8 @@ struct r600_bo *r600_bomgr_bo_create(struct r600_bomgr *mgr, */ static inline int radeon_bo_map(struct radeon *radeon, struct radeon_bo *bo) { + if (bo->map_count == 0 && !bo->data) + return radeon_bo_fixed_map(radeon, bo); bo->map_count++; return 0; } diff --git a/src/gallium/winsys/r600/drm/radeon_bo.c b/src/gallium/winsys/r600/drm/radeon_bo.c index 13b1d50..9a534dd 100644 --- a/src/gallium/winsys/r600/drm/radeon_bo.c +++ b/src/gallium/winsys/r600/drm/radeon_bo.c @@ -33,7 +33,7 @@ #include "xf86drm.h" #include "radeon_drm.h" -static int radeon_bo_fixed_map(struct radeon *radeon, struct radeon_bo *bo) +int radeon_bo_fixed_map(struct radeon *radeon, struct radeon_bo *bo) { struct drm_radeon_gem_mmap args; void *ptr; @@ -127,11 +127,6 @@ struct radeon_bo *radeon_bo(struct radeon *radeon, unsigned handle, return NULL; } } - if (radeon_bo_fixed_map(radeon, bo)) { - R600_ERR("failed to map bo\n"); - radeon_bo_reference(radeon, &bo, NULL); - return bo; - } if (handle) util_hash_table_set(radeon->bo_handles, (void *)(uintptr_t)handle, bo); -- 2.7.4
