drm/tegra: Fix comparison operator for buffer size

2018-07-09T08:33:45+00:00

Here we are checking for the buffer length, not an offset for writing to, so using > is correct. The current code incorrectly rejects a command buffer ending at the memory buffer's end. Signed-off-by: Mikko Perttunen Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

Merge tag 'drm/tegra/for-4.18-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next

drm/tegra: Changes for v4.18-rc1 This set enables IOMMU support in the gr2d and gr3d drivers and adds support for the zpos property on older Tegra generations. It also enables scaling filters and incorporates some rework to eliminate a private wrapper around struct drm_framebuffer. The remainder is mostly a random assortment of fixes and cleanups, as well as some preparatory work for destaging the userspace ABI, which is almost ready and is targetted for v4.19-rc1.

drm/tegra: vic: Track interface version

2018-05-18T20:00:41+00:00

Set the interface version implemented by the VIC module. This allows userspace to pass the correct command stream when programming the VIC module. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: gr3d: Track interface version

drm/tegra: Track client version

2018-05-18T19:59:51+00:00

Userspace needs to know the version of the interface implemented by a client so it can create the proper command streams. Allow individual drivers to store this version along with the client so that it can be returned to userspace upon opening a channel. Acked-by: Dmitry Osipenko Signed-off-by: Thierry Reding

drm/tegra: dc: Support rotation property

2018-05-18T19:56:21+00:00

Currently only the DRM_MODE_REFLECT_Y rotation is supported. The driver already supports reflection on the Y axis via a custom flag which is not very useful because it requires custom userspace. Add the standard rotation property that supports 0 degree rotation and Y axis reflection for primary and overlay planes to provide a better interface than the custom flag. v2: keep custom flag for ABI compatibility (Dmitry) Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Rename relocarray -> relocs for consistency

2018-05-18T19:51:25+00:00

All other array variables use a plural, and this is the only one using the *array suffix. This is confusing, so rename it for consistency. Reviewed-by: Dmitry Osipenko Tested-by: Dmitry Osipenko Signed-off-by: Thierry Reding

gpu: host1x: Store pointer to client in jobs

2018-05-18T19:50:24+00:00

Rather than storing some identifier derived from the application context that can't be used concretely anywhere, store a pointer to the client directly so that accesses can be made directly through that client object.
