drm/msm/gpu: Fix a couple memory leaks in debugfs

2018-11-30T16:34:44Z

The msm_gpu_open() function should free "show_priv" on error or it causes static checker warnings. Fixes: 4f776f4511c7 ("drm/msm/gpu: Convert the GPU show function to use the GPU state") Signed-off-by: Dan Carpenter Signed-off-by: Rob Clark Signed-off-by: Sean Paul

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

2018-07-30T12:49:56Z

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. Signed-off-by: Jordan Crouse Signed-off-by: Rob Clark

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

2018-07-30T12:49:48Z

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

2018-05-03T19:26:10Z

It's going away. v2: Try harder to find them all.

drm/msm: add a5xx specific debugfs

2018-02-20T15:41:20Z

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). Signed-off-by: Rob Clark

drm/msm/gpu: use pm-runtime

2017-04-08T10:59:31Z

We need to use pm-runtime properly when IOMMU is using device_link() to control it's own clocks. Signed-off-by: Rob Clark

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

2017-04-08T10:59:31Z

Each of the per-generation callbacks was doing this. Lets just simplify and move it into toplevel show() fxn. Signed-off-by: Rob Clark

drm/msm: Remove msm_debugfs_cleanup()

2017-03-08T10:24:45Z

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

2017-03-01T15:09:52Z

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

2016-12-30T11:08:28Z

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.
