From 46c64d4bfa01cda7d58c514164f8b127ab6741b7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Thu, 17 Dec 2009 06:02:28 +0100 Subject: drm/radeon/kms: allow rendering while no colorbuffer is set on r300 Because hardware cannot disable all colorbuffers directly to do depth-only rendering, a user should: - disable reading from a colorbuffer in blending - disable fastfill - set the color channel mask to 0 to prevent writing to a colorbuffer Signed-off-by: Dave Airlie --- drivers/gpu/drm/radeon/r100_track.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'drivers/gpu/drm/radeon/r100_track.h') diff --git a/drivers/gpu/drm/radeon/r100_track.h b/drivers/gpu/drm/radeon/r100_track.h index 7188c37..b27a699 100644 --- a/drivers/gpu/drm/radeon/r100_track.h +++ b/drivers/gpu/drm/radeon/r100_track.h @@ -67,13 +67,15 @@ struct r100_cs_track { unsigned immd_dwords; unsigned num_arrays; unsigned max_indx; + unsigned color_channel_mask; struct r100_cs_track_array arrays[11]; struct r100_cs_track_cb cb[R300_MAX_CB]; struct r100_cs_track_cb zb; struct r100_cs_track_texture textures[R300_TRACK_MAX_TEXTURE]; bool z_enabled; bool separate_cube; - + bool fastfill; + bool blend_read_enable; }; int r100_cs_track_check(struct radeon_device *rdev, struct r100_cs_track *track); -- cgit v1.1
