* dri/kms: Always zero out struct drm_mode_create_dumbThierry Reding2014-11-161-1/+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.

* dri: Add a new capabilities for drivers that can't share buffersGiovanni Campagna2014-07-301-3/+9
| | | | | | | | | | | | | | | | | | | The kms-dri swrast driver cannot share buffers using the GEM, so it must tell the loader to disable extensions relying on that, without disabling the image DRI extension altogether (which would prevent the loader from working at all). This requires a new gallium capability (which is queried on the pipe_screen and for swrast drivers it's forwarded to the winsys), and requires a new version of the DRI image extension. [Emil Velikov] - Rebased on top of gallium-dri megadrivers. - Drop PIPE_CAP_BUFFER_SHARE and sw_winsys::get_param hook. The can_share_buffer cap is set at InitScreen. We use a different InitScreen (and thus value for the cap) function for kms_dri, due to deeper differences originating from dri megadrivers. Signed-off-by: Emil Velikov <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | 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.

* swrast* (gallium, classic): add MESA_copy_sub_buffer support (v3)Dave Airlie2013-12-138-11/+26
| | | | | | | | | | | | | | | | | | | | | | | This patches add MESA_copy_sub_buffer support to the dri sw loader and then to gallium state tracker, llvmpipe, softpipe and other bits. It reuses the dri1 driver extension interface, and it updates the swrast loader interface for a new putimage which can take a stride. I've tested this with gnome-shell with a cogl hacked to reenable sub copies for llvmpipe and the one piglit test. I could probably split this patch up as well. v2: pass a pipe_box, to reduce the entrypoints, as per Jose's review, add to p_screen doc comments. v3: finish off winsys interfaces, add swrast classic support as well.

* winsys/sw/xlib: Prevent shared memory segment leakage.José Fonseca2013-04-241-0/+6
| | | | | | | | | | | | | | | | | | | | | | Running piglit with this was causing all sort of weird stuff happening to my desktop (Chromium webpages become blank, Qt Creator flickered, etc). I tracked this down to shared memory segment leakage when GL is not shutdown properly. The segments can be seen running `ipcs` and looking for nattch==0. This changes fixes this by calling shmctl(IPC_RMID) soon after creation (which does not remove the segment immediately, but simply marks it for removal when no more processes are attached). This matches src/mesa/drivers/x11/xm_buffer.c behaviour. v2: - move shmctl(IPC_RMID) after XShmAttach() for *BSD, per Chris Wilson - remove stray debug printfs, spotted by Ian Romanick NOTE: This is a candidate for stable branches.
