From: Dave Airlie Date: Wed, 28 May 2008 05:55:44 +0000 (+1000) Subject: mesa/drm/ttm: allow build against non-TTM aware libdrm X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0b734bd7cf921592eee441f759687e10f48a2cbc;p=mesa.git mesa/drm/ttm: allow build against non-TTM aware libdrm I'll release a libdrm 2.3.1 without TTM apis included from a special drm branch that should allow mesa 7.1 to build against it. I've had to turn off DRI2 stuff. --- diff --git a/configure.ac b/configure.ac index a250f75ea52..a73c754dfdf 100644 --- a/configure.ac +++ b/configure.ac @@ -478,6 +478,19 @@ AC_ARG_ENABLE([driglx-direct], [enable direct rendering in GLX for DRI @<:@default=enabled@:>@])], [driglx_direct="$enableval"], [driglx_direct="yes"]) +dnl ttm support +AC_ARG_ENABLE([ttm-api], + [AS_HELP_STRING([--enable-ttm-api], + [enable TTM API users])], + [ttmapi="$enableval"], + [ttmapi="no"]) + +if test "x$ttmapi" = "xyes"; then + save_CFLAGS=$CFLAGS + CFLAGS=$LIBDRM_CFLAGS + AC_CHECK_HEADERS([xf86mm.h],[],[AC_MSG_ERROR([xf86mm.h required for TTM.])],[#include "stdint.h"\n#include "drm.h"]) + CFLAGS=$save_CFLAGS +fi dnl Which drivers to build - default is chosen by platform AC_ARG_WITH([dri-drivers], @@ -516,6 +529,10 @@ if test "$mesa_driver" = dri; then DEFINES="$DEFINES -DGLX_USE_TLS -DPTHREADS" fi + if test "x$ttmapi" = xyes; then + DEFINES="$DEFINES -DTTM_API" + fi + if test "x$USING_EGL" = x1; then PROGRAM_DIRS="egl" fi @@ -934,6 +951,7 @@ if test "$mesa_driver" = dri; then dri_dirs=`echo $DRI_DIRS | $SED 's/^ *//;s/ */ /;s/ *$//'` echo " DRI drivers: $dri_dirs" echo " DRI driver dir: $DRI_DRIVER_INSTALL_DIR" + echo " TTM API support: $ttmapi" fi dnl Libraries diff --git a/src/mesa/drivers/dri/common/dri_bufmgr.h b/src/mesa/drivers/dri/common/dri_bufmgr.h index 4593eaf9f7a..0a726dc108a 100644 --- a/src/mesa/drivers/dri/common/dri_bufmgr.h +++ b/src/mesa/drivers/dri/common/dri_bufmgr.h @@ -219,4 +219,42 @@ void dri_post_process_relocs(dri_bo *batch_buf); void dri_post_submit(dri_bo *batch_buf, dri_fence **last_fence); int dri_bufmgr_check_aperture_space(dri_bo *bo); +#ifndef TTM_API +/* reuse some TTM API */ + +#define DRM_BO_MEM_LOCAL 0 +#define DRM_BO_MEM_TT 1 +#define DRM_BO_MEM_VRAM 2 +#define DRM_BO_MEM_PRIV0 3 +#define DRM_BO_MEM_PRIV1 4 +#define DRM_BO_MEM_PRIV2 5 +#define DRM_BO_MEM_PRIV3 6 +#define DRM_BO_MEM_PRIV4 7 + +#define DRM_BO_FLAG_READ (1ULL << 0) +#define DRM_BO_FLAG_WRITE (1ULL << 1) +#define DRM_BO_FLAG_EXE (1ULL << 2) +#define DRM_BO_MASK_ACCESS (DRM_BO_FLAG_READ | DRM_BO_FLAG_WRITE | DRM_BO_FLAG_EXE) +#define DRM_BO_FLAG_NO_EVICT (1ULL << 4) + +#define DRM_BO_FLAG_MAPPABLE (1ULL << 5) +#define DRM_BO_FLAG_SHAREABLE (1ULL << 6) + +#define DRM_BO_FLAG_CACHED (1ULL << 7) + +#define DRM_BO_FLAG_NO_MOVE (1ULL << 8) +#define DRM_BO_FLAG_CACHED_MAPPED (1ULL << 19) +#define DRM_BO_FLAG_FORCE_CACHING (1ULL << 13) +#define DRM_BO_FLAG_FORCE_MAPPABLE (1ULL << 14) +#define DRM_BO_FLAG_TILE (1ULL << 15) + +#define DRM_BO_FLAG_MEM_LOCAL (1ULL << 24) +#define DRM_BO_FLAG_MEM_TT (1ULL << 25) +#define DRM_BO_FLAG_MEM_VRAM (1ULL << 26) + +#define DRM_BO_MASK_MEM 0x00000000FF000000ULL + +#define DRM_FENCE_TYPE_EXE 0x00000001 +#endif + #endif diff --git a/src/mesa/drivers/dri/common/dri_util.c b/src/mesa/drivers/dri/common/dri_util.c index daa3fc58149..6efdf4312a5 100644 --- a/src/mesa/drivers/dri/common/dri_util.c +++ b/src/mesa/drivers/dri/common/dri_util.c @@ -771,8 +771,10 @@ static void driDestroyScreen(__DRIscreen *psp) (*psp->DriverAPI.DestroyScreen)(psp); if (psp->dri2.enabled) { +#ifdef TTM_API drmBOUnmap(psp->fd, &psp->dri2.sareaBO); drmBOUnreference(psp->fd, &psp->dri2.sareaBO); +#endif } else { (void)drmUnmap((drmAddress)psp->pSAREA, SAREA_MAX); (void)drmUnmap((drmAddress)psp->pFB, psp->fbSize); @@ -904,6 +906,7 @@ dri2CreateNewScreen(int scrn, int fd, unsigned int sarea_handle, const __DRIextension **extensions, const __DRIconfig ***driver_configs, void *data) { +#ifdef TTM_API static const __DRIextension *emptyExtensionList[] = { NULL }; __DRIscreen *psp; unsigned int *p; @@ -971,6 +974,9 @@ dri2CreateNewScreen(int scrn, int fd, unsigned int sarea_handle, psp->DriverAPI = driDriverAPI; return psp; +#else + return NULL; +#endif } static const __DRIextension **driGetExtensions(__DRIscreen *psp) diff --git a/src/mesa/drivers/dri/common/dri_util.h b/src/mesa/drivers/dri/common/dri_util.h index 8e1cdfc893f..203479e3267 100644 --- a/src/mesa/drivers/dri/common/dri_util.h +++ b/src/mesa/drivers/dri/common/dri_util.h @@ -53,7 +53,6 @@ #include #include #include -#include #include "GL/internal/glcore.h" #include "GL/internal/dri_interface.h" #include "GL/internal/dri_sarea.h" @@ -524,7 +523,9 @@ struct __DRIscreenRec { /* Flag to indicate that this is a DRI2 screen.
