drm/atomic: Remove drm_atomic_debugfs_cleanup()

2017-01-27T08:02:03Z

drm_debugfs_cleanup() now removes all minor->debugfs_list entries automatically, so no need to call drm_debugfs_remove_files(). Signed-off-by: Noralf Trønnes Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170126225621.12314-4-noralf@tronnes.org

drm: debugfs: Remove all files automatically on cleanup

2017-01-27T07:55:21Z

Instead of having the drivers call drm_debugfs_remove_files() in their drm_driver->debugfs_cleanup hook, do it automatically by traversing minor->debugfs_list. Also use debugfs_remove_recursive() so drivers who add their own debugfs files don't have to keep track of them for removal.

drm/atomic: cleanup debugfs entries on un-registering the driver.

2016-11-21T18:22:08Z

Cleanup the debugfs entries created by commit 6559c901cb48: drm/atomic: add debugfs file to dump out atomic state when the driver's minor gets un-registered. Without it, DRM drivers compiled as modules cannot be rmmod-ed and modprobed again.

drm/atomic: add debugfs file to dump out atomic state

2016-11-08T21:38:03Z

Useful to dump current state from debugfs, if turning on the drm.debug bit is too much overhead. The drm_state_dump() can also be used by drivers, for example to implement a module param that dumps state on error irqs.

drm: Add API for capturing frame CRCs

2016-10-17T14:44:34Z

Adds files and directories to debugfs for controlling and reading frame CRCs, per CRTC: dri/0/crtc-0/crc dri/0/crtc-0/crc/control dri/0/crtc-0/crc/data Drivers can implement the set_crc_source callback() in drm_crtc_funcs to start and stop generating frame CRCs and can add entries to the output by calling drm_crtc_add_crc_entry. v2: - Lots of good fixes suggested by Thierry. - Added documentation. - Changed the debugfs layout. - Moved to allocate the entries circular queue once when frame generation gets enabled for the first time. v3: - Use the control file just to select the source, and start and stop capture when the data file is opened and closed, respectively. - Make variable the number of CRC values per entry, per source. - Allocate entries queue each time we start capturing as now there isn't a fixed number of CRC values per entry. - Store the frame counter in the data file as a 8-digit hex number. - For sources that cannot provide useful frame numbers, place XXXXXXXX in the frame field. v4: - Build only if CONFIG_DEBUG_FS is enabled. - Use memdup_user_nul. - Consolidate calculation of the size of an entry in a helper. - Add 0x prefix to hex numbers in the data file. - Remove unnecessary snprintf and strlen usage in read callback. v5: - Made the crcs array in drm_crtc_crc_entry fixed-size - Lots of other smaller improvements suggested by Emil Velikov v7: - Move definition of drm_debugfs_crtc_crc_add to drm_internal.h v8: - Call debugfs_remove_recursive when we fail to create the minor device v9: - Register the debugfs directory for a crtc from drm_crtc_register_all() v10: - Don't let debugfs failures interrupt CRTC registration (Emil Velikov) v11: - Remove extra brace that broke compilation.

drm: Move piles of functions from drmP.h to drm_internal.h

This way drivers can't grow crazy ideas any more, and it also helps a bit in reviewing EXPORT_SYMBOLS. v2: Even more stuff. Unfortunately we can't move drm_vm_open_locked because exynos does some horrible stuff with it. Signed-off-by: Daniel Vetter
