| Subject | [PATCH v3 0/6] Miscellaneous improvements to Host1x and TegraDRM |
| Message-ID | <uuGA1-Fm-5@gated-at.bofh.it> |
New in v3: - Renamed *syncpt_assign_channel to *syncpt_assign_to_channel - Disassembler ignores opcodes not supported on the particular chip - Further cleanup in u64_to_user_ptr patch New in v2: - Changes in syncpoint protection and u64_to_user_ptr patches. See the patches for notes. - Added patch to support more opcodes in the debug dump disassembly. - Added patch to fix an incorrect comment. Thanks, Mikko Patch v1 notes: Hi all, here are some new features and improvements. Patch 1 enables syncpoint protection which prevents channels from touching syncpoints not belonging to them on Tegra186. Patch 2 enables the gather filter which prevents userspace command buffers from using CDMA commands usually reserved for the kernel. A test is available at git://github.com/cyndis/host1x_test, branch gather-filter. Patch 3 greatly improves formatting of debug dumps spewed by host1x in case of job timeouts. They are now actually readable by humans without use of additional scripts. Patch 4 is a simple aesthetical fix to the TegraDRM submit path. Everything was tested on TX1 and TX2 and should be applied on the previously posted Tegra186 support series.
