From ab9e1f5966591dc3e811418e96ba04f284c52458 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 13 Jul 2010 11:11:11 +1000 Subject: drm/radeon: add basic zmask/hiz support (v4) This interface allows userspace to request hyperz support, it probably needs more locking, and really reporting that you can have hyperz is racy since someone else might get it before you do. v2: modify so we pass 0 valued packets to let DDX/r300c keep working. also fixed incorrect 0x4f1c reference. v3: fixup zb_bw_cntl so older drivers keep working v4: add locking, fixup SC_HYPERZ_EN - patch stream to disable hiz Signed-off-by: Dave Airlie --- drivers/gpu/drm/radeon/r100.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'drivers/gpu/drm/radeon/r100.c') diff --git a/drivers/gpu/drm/radeon/r100.c b/drivers/gpu/drm/radeon/r100.c index 4c48df464355..e817a0bb5eb4 100644 --- a/drivers/gpu/drm/radeon/r100.c +++ b/drivers/gpu/drm/radeon/r100.c @@ -1803,6 +1803,11 @@ static int r100_packet3_check(struct radeon_cs_parser *p, return r; break; /* triggers drawing using indices to vertex buffer */ + case PACKET3_3D_CLEAR_HIZ: + case PACKET3_3D_CLEAR_ZMASK: + if (p->rdev->hyperz_filp != p->filp) + return -EINVAL; + break; case PACKET3_NOP: break; default: -- cgit v1.2.2
