2016-05-23gbm: Add map/unmap functionsRob Herring7-2/+165
This adds map and unmap functions to GBM utilizing the DRIimage extension mapImage/unmapImage functions or existing internal mapping for dumb buffers. Unlike prior attempts, this version provides a region to map and usage flags for the mapping. The operation follows the same semantics as the gallium transfer_map() function. This was tested with GBM based gralloc on Android.

2015-09-15gbm: convert gbm bo format to fourcc format on dma-buf importRay Strode1-1/+17
At the moment if a gbm buffer is imported and the gbm buffer has an old-style GBM_BO_FORMAT format, the import will crash, since it's passed directly to DRI functions that expect a fourcc format (as provided by the newer GBM_FORMAT definitions) This commit addresses the problem in two ways: 1) it prevents invalid formats from leading to a crash by returning EINVAL if the image couldn't be created 2) it translates GBM_BO_FORMAT formats into the comparable GBM_FORMAT formats.

2014-11-16dri/kms: Always zero out struct drm_mode_create_dumbThierry Reding1-0/+1
The DRM_IOCTL_MODE_CREATE_DUMB (and others) IOCTL isn't very rigorously specified, which has the effect that some kernel drivers do not consider the .pitch and .size fields of struct drm_mode_create_dumb outputs only. Instead they will use these as lower bounds and overwrite them only if the values that they compute are larger than what userspace provided. This works if and only if userspace initializes the fields explicitly to either 0 or some meaningful value. However, if userspace just leaves the values uninitialized and the struct drm_mode_create_dumb is allocated on the stack for example, the driver may try to overallocate buffers. Fortunately most userspace does zero out the structure before passing it to the IOCTL, but there are rare exceptions. Mesa is one of them. In an attempt to rectify this situation, kernel drivers are being updated to not use the .pitch and .size fields as inputs. However in order to fix the issue with older kernels, make sure that Mesa always zeros out the structure as well. Future IOCTLs should be more rigorously defined so that structures can be validated and IOCTLs rejected if output fields aren't set to zero.

2014-07-30gallium: Add a dumb drm/kms winsys backed swrast providerGiovanni Campagna1-4/+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.

2014-07-24gbm: Search LIBGL_DRIVERS_PATH if GBM_DRIVERS_PATH is not setDylan Baker1-1/+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>
