drm/msm/gpu: Capture the GPU state on a GPU hang

2018-07-30T12:49:56+00:00

Capture the GPU state on a GPU hang and store it for later playback
via the devcoredump facility. Only one crash state is stored at a
time on the assumption that the first hang is usually the most
interesting. The existing crash state can be cleared after capturing
it and then a new one will be captured on the next hang.

drm/msm/gpu: Convert the GPU show function to use the GPU state

2018-07-30T12:49:48+00:00

Convert the existing GPU show function to use the GPU state to
dump the information rather than reading it directly from the hardware.
This will require an additional step to capture the state before
dumping it for the existing nodes but it will greatly facilitate reusing
the same code for dumping a previously captured state from a GPU hang.

drm/msm: Don't setup control node debugfs files

2018-05-03T19:26:10+00:00

It's going away.

v2: Try harder to find them all.

drm/msm: add a5xx specific debugfs

2018-02-20T15:41:20+00:00

Add some debugfs to dump out PFP and ME microcontroller state, as well
as some of the queues (MEQ and ROQ).  Also add a debugfs file to trigger
a GPU reset (and reloading the firmware on next submit).

drm/msm/gpu: use pm-runtime

2017-04-08T10:59:31+00:00

We need to use pm-runtime properly when IOMMU is using device_link() to
control it's own clocks.

drm/msm/gpu: move suspend/resume into debugfs->show

2017-04-08T10:59:31+00:00

Each of the per-generation callbacks was doing this.  Lets just simplify
and move it into toplevel show() fxn.

drm/msm: Remove msm_debugfs_cleanup()

2017-03-08T10:24:45+00:00

Move the contents of msm_debugfs_cleanup() to msm_drm_uninit() to free
up the drm_driver->debugfs_cleanup callback. Also remove the
mdp_kms_funcs->debugfs_cleanup callback which has no users.

drm/msm: Remove drm_debugfs_remove_files() calls

2017-03-01T15:09:52+00:00

drm_debugfs_cleanup() now removes all minor->debugfs_list entries
automatically, so it's not necessary to call
drm_debugfs_remove_files(). Additionally it uses
debugfs_remove_recursive() to clean up the debugfs files, so no need
to do that.

drm/mm: Convert to drm_printer

2016-12-30T11:08:28+00:00

Including all drivers. I thought about keeping small compat functions
to avoid having to change all drivers. But I really like the
drm_printer idea, so figured spreading it more widely is a good thing.

v2: Review from Chris:
- Natural argument order and better name for drm_mm_print.
- show_mm() macro in the selftest.
