Subject: [PATCH v2 0/6] Miscellaneous improvements to Host1x and TegraDRM
Date: Tue, 5 Sep 2017 11:10:23 +0300 [thread overview]
Message-ID: <20170905081029.19769-1-mperttunen@nvidia.com> (raw)
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.
Cheers,
Mikko
