From 10b3e64bcada2e68144cc6ed40f7d760aff873e2 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Tue, 14 Jul 2009 21:19:32 -0400 Subject: [PATCH] R6xx/r7xx: implement memcpy buffer swaps This allows double buffered apps to run, but perfomance will be awful until we implement something faster. You must update to the latest kernel modules. --- src/mesa/drivers/dri/radeon/radeon_common.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/src/mesa/drivers/dri/radeon/radeon_common.c b/src/mesa/drivers/dri/radeon/radeon_common.c index 60d6bbb5af9..e75e6a33de0 100644 --- a/src/mesa/drivers/dri/radeon/radeon_common.c +++ b/src/mesa/drivers/dri/radeon/radeon_common.c @@ -475,6 +475,24 @@ void radeonCopyBuffer( __DRIdrawablePrivate *dPriv, if (!n) continue; + if (IS_R600_CLASS(rmesa->radeonScreen)) { + int src_pitch = rmesa->radeonScreen->backPitch * rmesa->radeonScreen->cpp; + int dst_pitch = rmesa->radeonScreen->frontPitch * rmesa->radeonScreen->cpp; + char *src = (char *)rmesa->radeonScreen->driScreen->pFB + rmesa->radeonScreen->backOffset; + char *dst = (char *)rmesa->radeonScreen->driScreen->pFB + rmesa->radeonScreen->frontOffset; + int j; + drm_clip_rect_t *pb = rmesa->sarea->boxes; + + for (j = 0; j < n; j++) { + int x = pb[j].x1; + int y = pb[j].y1; + int w = pb[j].x2 - x; + int h = pb[j].y2 - y; + + r600_sw_blit(src, src_pitch, dst, dst_pitch, x, y, w, h, rmesa->radeonScreen->cpp); + } + } + ret = drmCommandNone( rmesa->dri.fd, DRM_RADEON_SWAP ); if ( ret ) { -- 2.30.2
