From ea55f8ed8fc18245d74e04c0ae8e1a4911a37f26 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Michel=20D=C3=A4nzer?= Date: Wed, 2 Sep 2009 16:00:30 +0200 Subject: [PATCH] st/xorg: Add support for xserver Git master DRI2 interface. Reorganize to handle both interfaces with common code. --- src/gallium/state_trackers/xorg/xorg_dri2.c | 231 ++++++++++++++++++---------- src/gallium/state_trackers/xorg/xorg_exa.h | 1 + 2 files changed, 151 insertions(+), 81 deletions(-) diff --git a/src/gallium/state_trackers/xorg/xorg_dri2.c b/src/gallium/state_trackers/xorg/xorg_dri2.c index 3b90421..537ce2d 100644 --- a/src/gallium/state_trackers/xorg/xorg_dri2.c +++ b/src/gallium/state_trackers/xorg/xorg_dri2.c @@ -33,6 +33,7 @@ #include "xf86_OSproc.h" #include "xorg_tracker.h" +#include "xorg_exa.h" #include "dri2.h" @@ -47,62 +48,55 @@ typedef struct { struct pipe_fence_handle *fence; } *BufferPrivatePtr; -static DRI2BufferPtr -driCreateBuffers(DrawablePtr pDraw, unsigned int *attachments, int count) +static Bool +driDoCreateBuffer(DrawablePtr pDraw, DRI2BufferPtr buffer, unsigned int format) { - struct pipe_texture *depth, *tex; - struct pipe_buffer *buf; + struct pipe_texture *tex = NULL; ScreenPtr pScreen = pDraw->pScreen; ScrnInfoPtr pScrn = xf86Screens[pScreen->myNum]; modesettingPtr ms = modesettingPTR(pScrn); - BufferPrivatePtr privates; - DRI2BufferPtr buffers; + struct exa_pixmap_priv *exa_priv; + BufferPrivatePtr private = buffer->driverPrivate; PixmapPtr pPixmap; unsigned stride, handle; - boolean have_depth = FALSE, have_stencil = FALSE; - int i; - - buffers = xcalloc(count, sizeof *buffers); - if (!buffers) - goto fail_buffers; - - privates = xcalloc(count, sizeof *privates); - if (!privates) - goto fail_privates; - - for (i = 0; i < count; i++) { - if (attachments[i] == DRI2BufferDepth) - have_depth = TRUE; - else if (attachments[i] == DRI2BufferStencil) - have_stencil = TRUE; - } - - if (have_stencil && !have_depth) - FatalError("Doesn't support only stencil yet\n"); - depth = NULL; - for (i = 0; i < count; i++) { - pPixmap = NULL; - tex = NULL; - buf = NULL; - if (attachments[i] == DRI2BufferFrontLeft) { - if (pDraw->type == DRAWABLE_PIXMAP) - pPixmap = (PixmapPtr) pDraw; - else - pPixmap = (*pScreen->GetWindowPixmap)((WindowPtr) pDraw); - pPixmap->refcnt++; - } else if (attachments[i] == DRI2BufferStencil) { - pipe_texture_reference(&tex, depth); - } else if (attachments[i] == DRI2BufferDepth) { + if (pDraw->type == DRAWABLE_PIXMAP) + pPixmap = (PixmapPtr) pDraw; + else + pPixmap = (*pScreen->GetWindowPixmap)((WindowPtr) pDraw); + exa_priv = exaGetPixmapDriverPrivate(pPixmap); + + switch (buffer->attachment) { + default: + if (buffer->attachment != DRI2BufferFakeFrontLeft || + pDraw->type != DRAWABLE_PIXMAP) { + private->pPixmap = (*pScreen->CreatePixmap)(pScreen, pDraw->width, + pDraw->height, + pDraw->depth, + 0); + } + break; + case DRI2BufferFrontLeft: + break; + case DRI2BufferStencil: + case DRI2BufferDepthStencil: + if (exa_priv->depth_stencil_tex && + !pf_is_depth_stencil(exa_priv->depth_stencil_tex->format)) + exa_priv->depth_stencil_tex = NULL; + /* Fall through */ + case DRI2BufferDepth: + if (exa_priv->depth_stencil_tex) + pipe_texture_reference(&tex, exa_priv->depth_stencil_tex); + else { struct pipe_texture template; memset(&template, 0, sizeof(template)); template.target = PIPE_TEXTURE_2D; - if (have_stencil) + if (buffer->attachment == DRI2BufferDepth) template.format = ms->ds_depth_bits_last ? - PIPE_FORMAT_S8Z24_UNORM : PIPE_FORMAT_Z24S8_UNORM; - else - template.format = ms->d_depth_bits_last ?
