From deadd47aab68d4914d70b19fa08f834623f2e0a7 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 19 Oct 2005 00:53:05 +0000 Subject: [PATCH] Bug #4615: Fix the SiS driver for the renderbuffer changes. Previously, all drirenderbuffers pointed at screen offset 0 and NULL. Instead, set up the front buffer at startup but leave the others for later, since sis allocates them on demand rather than using the static method of the other non-sis-descendent drivers. Some basic apps work, but fallbacks may be broken still. --- src/mesa/drivers/dri/sis/sis_alloc.c | 87 +++++++-------- src/mesa/drivers/dri/sis/sis_clear.c | 6 +- src/mesa/drivers/dri/sis/sis_context.c | 24 +++-- src/mesa/drivers/dri/sis/sis_context.h | 39 ++++--- src/mesa/drivers/dri/sis/sis_dd.c | 137 +++++++++++++++++++----- src/mesa/drivers/dri/sis/sis_screen.c | 76 +++---------- src/mesa/drivers/dri/sis/sis_screen.h | 1 - src/mesa/drivers/dri/sis/sis_span.c | 58 +++++----- src/mesa/drivers/dri/sis/sis_span.h | 2 +- src/mesa/drivers/dri/sis/sis_state.c | 15 ++- src/mesa/drivers/dri/sis/sis_texstate.c | 4 +- 11 files changed, 252 insertions(+), 197 deletions(-) diff --git a/src/mesa/drivers/dri/sis/sis_alloc.c b/src/mesa/drivers/dri/sis/sis_alloc.c index b808daae3d2..99342153657 100644 --- a/src/mesa/drivers/dri/sis/sis_alloc.c +++ b/src/mesa/drivers/dri/sis/sis_alloc.c @@ -136,45 +136,42 @@ sisFreeAGP( sisContextPtr smesa, void *handle ) void sisAllocZStencilBuffer( sisContextPtr smesa ) { - GLuint z_depth; - GLuint totalBytes; - int width2; - - GLubyte *addr; - - z_depth = ( smesa->glCtx->Visual.depthBits + + int cpp = ( smesa->glCtx->Visual.depthBits + smesa->glCtx->Visual.stencilBits ) / 8; + unsigned char *addr; - width2 = ALIGNMENT( smesa->width * z_depth, 4 ); + smesa->depth.bpp = cpp * 8; + smesa->depth.pitch = ALIGNMENT(smesa->driDrawable->w * cpp, 4); + smesa->depth.size = smesa->depth.pitch * smesa->driDrawable->h; + smesa->depth.size += Z_BUFFER_HW_PLUS; - totalBytes = smesa->height * width2 + Z_BUFFER_HW_PLUS; - - addr = sisAllocFB( smesa, totalBytes, &smesa->zbFree ); + addr = sisAllocFB(smesa, smesa->depth.size, &smesa->depth.handle); if (addr == NULL) sis_fatal_error("Failure to allocate Z buffer.\n"); + addr = (char *)ALIGNMENT((unsigned long)addr, Z_BUFFER_HW_ALIGNMENT); - if (SIS_VERBOSE & VERBOSE_SIS_BUFFER) { - fprintf(stderr, "sis_alloc_z_stencil_buffer: addr=%p\n", addr); - } + smesa->depth.map = addr; + smesa->depth.offset = addr - smesa->FbBase; - addr = (GLubyte *)ALIGNMENT( (unsigned long)addr, Z_BUFFER_HW_ALIGNMENT ); - - smesa->depthbuffer = (void *) addr; - smesa->depthPitch = width2; - smesa->depthOffset = (unsigned long)addr - (unsigned long)smesa->FbBase; + /* stencil buffer is same as depth buffer */ + smesa->stencil.size = smesa->depth.size; + smesa->stencil.offset = smesa->depth.offset; + smesa->stencil.handle = smesa->depth.handle; + smesa->stencil.pitch = smesa->depth.pitch; + smesa->stencil.bpp = smesa->depth.bpp; + smesa->stencil.map = smesa->depth.map; /* set pZClearPacket */ memset( &smesa->zClearPacket, 0, sizeof(ENGPACKET) ); - smesa->zClearPacket.dwSrcPitch = (z_depth == 2) ? 0x80000000 : 0xf0000000; - smesa->zClearPacket.dwDestBaseAddr = (unsigned long)(addr - - (unsigned long)smesa->FbBase); - smesa->zClearPacket.wDestPitch = width2; + smesa->zClearPacket.dwSrcPitch = (cpp == 2) ? 0x80000000 : 0xf0000000; + smesa->zClearPacket.dwDestBaseAddr = smesa->depth.offset; + smesa->zClearPacket.wDestPitch = smesa->depth.pitch; smesa->zClearPacket.stdwDestPos.wY = 0; smesa->zClearPacket.stdwDestPos.wX = 0; smesa->zClearPacket.wDestHeight = smesa->virtualY; - smesa->zClearPacket.stdwDim.wWidth = (GLshort)width2 / z_depth; + smesa->zClearPacket.stdwDim.wWidth = smesa->depth.pitch / cpp; smesa->zClearPacket.stdwDim.wHeight = (GLshort)smesa->height; smesa->zClearPacket.stdwCmd.cRop = 0xf0; @@ -188,43 +185,40 @@ sisAllocZStencilBuffer( sisContextPtr smesa ) void sisFreeZStencilBuffer( sisContextPtr smesa ) { - sisFreeFB( smesa, smesa->zbFree ); - smesa->zbFree = NULL; - smesa->depthbuffer = NULL; + sisFreeFB(smesa, smesa->depth.handle); + smesa->depth.map = NULL; + smesa->depth.offset = 0; } void sisAllocBackbuffer( sisContextPtr smesa ) { - GLuint depth = smesa->bytesPerPixel; - GLuint size, width2; - - char *addr; + int cpp = smesa->bytesPerPixel; + unsigned char *addr; - width2 = (depth == 2) ?
