* gbm: Log at least one dlerror() when we fail to open any drivers.Eric Anholt2014-07-301-0/+1
| | | | | | | | | | | | We don't want to log every single error (such as all the ones where the file wasn't even present in our list of search paths), but if you didn't find any driver, then seeing at least one error is useful (since the common case as a developer is a single DEFAULT_DRIVER_DIR or GBM_DRIVERS_PATH entry). v2: Rebase on swrast changes.

* gallium: Add a dumb drm/kms winsys backed swrast providerGiovanni Campagna2014-07-301-4/+34
| | | | | | | | | | | | | | | | | | | | | | Add a new winsys and target that can be used with a dri2 state tracker and loader instead of drisw. This allows to use gbm as a dri2/image loader and avoid the extra copy from the backbuffer to the shadow frontbuffer. The new driver is called "kms_swrast", and is loaded by gbm as a fallback, because it is only useful with the gbm platform (as no buffer sharing is possible) To force select the driver set the environment variable GBM_ALWAYS_SOFTWARE [Emil Velikov] - Rebase on top of gallium megadriver. - s/text/test/ in configure.ac (Spotted by Andreas Pokorny). - Add scons support for winsys/sw/kms-dri and fix the build. - Provide separate DriverAPI, due to different InitScreen hook.

* Add support for swrast to the DRM EGL platformGiovanni Campagna2014-07-304-27/+237
| | | | | | | | | | | | | | | | | | | | Turn GBM into a swrast loader (providing putimage/getimage backed by a dumb KMS buffer). This allows to run KMS+DRM GL applications (such as weston or mutter-wayland) unmodified on cards that don't have any client side HW acceleration component but that can do modeset (examples include simpledrm and qxl) [Emil Velikov] - Fix make check. - Split dri_open_driver() from dri_load_driver(). - Don't try to bind the swrast extensions when using dri. - Handle swrast->CreateNewScreen() failure. - strdup the driver_name, as it's free'd at destruction. - s/LIBGL_ALWAYS_SOFTWARE/GBM_ALWAYS_SOFTWARE/ - Move gbm_dri_bo_map/unmap to gbm_driiint.h. - Correct swrast fallback logic.

* gbm: Search LIBGL_DRIVERS_PATH if GBM_DRIVERS_PATH is not setDylan Baker2014-07-241-1/+11
| | | | | | | | | | | | | | | | | | | | | The GBM_DRIVERS_PATH environment variable is not documented, and only used to set the location of gbm drivers, while LIBGL_DRIVERS_PATH is used for everything else, and is documented. Generally this split leads to confusion as to why gbm doesn't work. This patch will read LIBGL_DRIVERS_PATH as a fallback if GBM_DRIVERS_PATH is not set. The comments clearly indicate that using LIBGL_DRIVERS_PATH is preferred over GBM_DRIVERS_PATH. v2: - Use GBM_DRIVERS_PATH as a fallback v3: [jordan.l.justen@intel.com] - Make LIBGL_DRIVERS_PATH the fallback Signed-off-by: Dylan Baker <baker.dylan.c@gmail.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Kristian Høgsberg <krh@bitplanet.net>

* Make DRI dependencies and build depend on the targetJon TURNEY2014-05-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Don't require xcb-dri[23] etc. if we aren't building for a target with DRM, as we won't be using dri[23] - Enable a more fine-grained control of what DRI code is built, so that a libGL using direct swrast can be built on targets which don't have DRM. The HAVE_DRI automake conditional is retired in favour of a number of other conditionals: HAVE_DRI2 enables building of code using the DRI2 interface (and possibly DRI3 with HAVE_DRI3) HAVE_DRISW enables building of DRI swrast HAVE_DRICOMMON enables building of target-independent DRI code, and also enables some makefile cases where a more detailled decision is made at a lower level. HAVE_APPLEDRI enables building of an Apple-specific direct rendering interface, still which requires additional fixing up to build properly. v2: Place xfont.c and drisw_glx.c into correct categories.

* automake: ask the linker to do garbage collectionEmil Velikov2014-03-311-0/+1
| | | | | | | | | | | | | | By doing GC the linker removes all the symbols that are not referenced and/or used by the final library.
