From cf4ccd016bae1a03bb38170eb54b5db4b04e0545 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 18 Nov 2011 10:19:47 -0500 Subject: drm/radeon/kms: add 6xx/7xx CS parser for async DMA (v2) Allows us to use the DMA ring from userspace. DMA doesn't have a good NOP packet in which to embed the reloc idx, so userspace has to add a reloc for each buffer used and order them to match the command stream. v2: fix address bounds checking, reloc indexing Signed-off-by: Alex Deucher --- drivers/gpu/drm/radeon/radeon.h | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/gpu/drm/radeon/radeon.h') diff --git a/drivers/gpu/drm/radeon/radeon.h b/drivers/gpu/drm/radeon/radeon.h index 285fb3f203af..5dc744d43d12 100644 --- a/drivers/gpu/drm/radeon/radeon.h +++ b/drivers/gpu/drm/radeon/radeon.h @@ -839,6 +839,7 @@ struct radeon_cs_parser { struct radeon_cs_reloc *relocs; struct radeon_cs_reloc **relocs_ptr; struct list_head validated; + unsigned dma_reloc_idx; /* indices of various chunks */ int chunk_ib_idx; int chunk_relocs_idx; -- cgit v1.2.2
