From: Zack Rusin Date: Thu, 11 Feb 2010 00:00:35 +0000 (-0500) Subject: st/dri, st/xorg: fix buffers that have attachements of different depth X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=59b4146a5dbeb108b53fc9c4132095e264ba04be;p=mesa.git st/dri, st/xorg: fix buffers that have attachements of different depth we actually need to specify the formats for different attachements, otherwise if the color buffer is 24bpp and the app asks for 16bpp depth buffer than we end up fetching the depth from the drawable which is 24bpp and end up creating the wrong depth buffer. use the new getBuffersWithFormat extension to pass the depth correctly. --- diff --git a/src/gallium/state_trackers/dri/dri_drawable.c b/src/gallium/state_trackers/dri/dri_drawable.c index ff21f2f9580..97277c05072 100644 --- a/src/gallium/state_trackers/dri/dri_drawable.c +++ b/src/gallium/state_trackers/dri/dri_drawable.c @@ -132,14 +132,22 @@ dri_get_buffers(__DRIdrawable * dPriv) boolean have_depth = FALSE; int i, count; - buffers = (*dri_screen->dri2.loader->getBuffers) (dri_drawable, - &dri_drawable->w, - &dri_drawable->h, - drawable->attachments, - drawable-> - num_attachments, &count, - dri_drawable-> - loaderPrivate); + if ((dri_screen->dri2.loader + && (dri_screen->dri2.loader->base.version > 2) + && (dri_screen->dri2.loader->getBuffersWithFormat != NULL))) + buffers = (*dri_screen->dri2.loader->getBuffersWithFormat) + (dri_drawable, &dri_drawable->w, &dri_drawable->h, + drawable->attachments, drawable->num_attachments, + &count, dri_drawable->loaderPrivate); + else + buffers = (*dri_screen->dri2.loader->getBuffers) (dri_drawable, + &dri_drawable->w, + &dri_drawable->h, + drawable->attachments, + drawable-> + num_attachments, &count, + dri_drawable-> + loaderPrivate); if (buffers == NULL) { return; @@ -346,12 +354,12 @@ dri_create_buffer(__DRIscreen * sPriv, case 24: if (visual->stencilBits == 0) { drawable->depth_stencil_format = (screen->d_depth_bits_last) ?
