The biggest change is the removal of the /dev/host1x device. Syncpoints are now allocated directly through the TegraDRM API. Direct userspace fence interfaces have been removed as there is currently no upstream use for them. Otherwise, there's a whole lot of smaller fixes and cosmetic improvements. Some previously discussed items that are not (fully) implemented here: - Per-job syncpoint allocation - this is easy to add in afterwards in a backwards compatible manner, so I left it out. I have prototyped it locally in case we need it. - Full support for syncobjs - currently only two syncobjs are taken, one in and one out, as currently there is no userspace that would need more than that, and it is also relatively easy to extend. - Constructing jobs in a non-CDMA pushbuffer. This should not cause any UAPI changes and will require further design work. The following pieces of userspace have been updated to support this revision of the UAPI: * vaapi-tegra-driver - https://github.com/cyndis/vaapi-tegra-driver Experimental support for MPEG2 and H264 decoding on T210, T186 and T194. * xf86-video-opentegra - https://github.com/grate-driver/xf86-video-opentegra X11 userspace acceleration driver for Tegra20, Tegra30, and Tegra114. * grate - https://github.com/grate-driver/grate 3D rendering testbed for Tegra20, Tegra30, and Tegra114 The series can be also found in https://github.com/cyndis/linux/commits/work/tegradrm-v6.
