Subject[PATCH v3 0/6] Miscellaneous improvements to Host1x and TegraDRM
Date
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.

Cheers,
Mikko
