From 27072152075e7542fb52a64054fae921b87f9085 Mon Sep 17 00:00:00 2001 From: Thomas Zimmermann Date: Thu, 13 Jun 2019 09:30:36 +0200 Subject: drm/ast: Pin and map cursor source BO during update The ast driver used to lock the cursor source BO during updates. Locking should be done internally by the BO's implementation, so we pin it instead to system memory. The mapping information is also stored in the BO. No need to have an extra argument to the kmap function. v2: * pin cursor BOs to current location Signed-off-by: Thomas Zimmermann Acked-by: Gerd Hoffmann Link: https://patchwork.freedesktop.org/patch/msgid/20190613073041.29350-5-tzimmermann@suse.de --- drivers/gpu/drm/ast/ast_mode.c | 37 ++++++++++++++++--------------------- 1 file changed, 16 insertions(+), 21 deletions(-) (limited to 'drivers/gpu/drm') diff --git a/drivers/gpu/drm/ast/ast_mode.c b/drivers/gpu/drm/ast/ast_mode.c index dce3aeb41c1a..ffccbef962a4 100644 --- a/drivers/gpu/drm/ast/ast_mode.c +++ b/drivers/gpu/drm/ast/ast_mode.c @@ -1183,9 +1183,8 @@ static int ast_cursor_set(struct drm_crtc *crtc, u64 gpu_addr; u32 csum; int ret; - struct ttm_bo_kmap_obj uobj_map; u8 *src, *dst; - bool src_isiomem, dst_isiomem; + if (!handle) { ast_hide_cursor(crtc); return 0; @@ -1201,31 +1200,25 @@ static int ast_cursor_set(struct drm_crtc *crtc, } gbo = drm_gem_vram_of_gem(obj); - ret = drm_gem_vram_lock(gbo, false); + ret = drm_gem_vram_pin(gbo, 0); if (ret) - goto fail; - - memset(&uobj_map, 0, sizeof(uobj_map)); - src = drm_gem_vram_kmap_at(gbo, true, &src_isiomem, &uobj_map); + goto err_drm_gem_object_put_unlocked; + src = drm_gem_vram_kmap(gbo, true, NULL); if (IS_ERR(src)) { ret = PTR_ERR(src); - goto fail_unlock; + goto err_drm_gem_vram_unpin; } - if (src_isiomem == true) - DRM_ERROR("src cursor bo should be in main memory\n"); dst = drm_gem_vram_kmap(drm_gem_vram_of_gem(ast->cursor_cache), - false, &dst_isiomem); + false, NULL); if (IS_ERR(dst)) { ret = PTR_ERR(dst); - goto fail_unlock; + goto err_drm_gem_vram_kunmap; } - if (dst_isiomem == false) - DRM_ERROR("dst bo should be in VRAM\n"); dst_gpu = drm_gem_vram_offset(drm_gem_vram_of_gem(ast->cursor_cache)); if (dst_gpu < 0) { ret = (int)dst_gpu; - goto fail_unlock; + goto err_drm_gem_vram_kunmap; } dst += (AST_HWC_SIZE + AST_HWC_SIGNATURE_SIZE)*ast->next_cursor; @@ -1233,9 +1226,6 @@ static int ast_cursor_set(struct drm_crtc *crtc, /* do data transfer to cursor cache */ csum = copy_cursor_image(src, dst, width, height); - drm_gem_vram_kunmap_at(gbo, &uobj_map); - drm_gem_vram_unlock(gbo); - /* write checksum + signature */ { struct drm_gem_vram_object *dst_gbo = @@ -1263,12 +1253,17 @@ static int ast_cursor_set(struct drm_crtc *crtc, ast_show_cursor(crtc); + drm_gem_vram_kunmap(gbo); + drm_gem_vram_unpin(gbo); drm_gem_object_put_unlocked(obj); + return 0; -fail_unlock: - drm_gem_vram_unlock(gbo); -fail: +err_drm_gem_vram_kunmap: + drm_gem_vram_kunmap(gbo); +err_drm_gem_vram_unpin: + drm_gem_vram_unpin(gbo); +err_drm_gem_object_put_unlocked: drm_gem_object_put_unlocked(obj); return ret; } -- cgit v1.2.3
