drm/debugfs: fix plain echo to connector "force" attribute

2020-08-21T07:48:05+00:00

[ Upstream commit c704b17071c4dc571dca3af4e4151dac51de081a ] Using plain echo to set the "force" connector attribute fails with -EINVAL, because echo appends a newline to the output. Replace strcmp with sysfs_streq to also accept strings that end with a newline. v2: use sysfs_streq instead of stripping trailing whitespace Signed-off-by: Michael Tretter Reviewed-by: Jani Nikula Signed-off-by: Emil Velikov Link: https://patchwork.freedesktop.org/patch/msgid/20170817104307.17124-1-m.tretter@pengutronix.de Signed-off-by: Sasha Levin

drm/atomic: Remove drm_atomic_debugfs_cleanup()

2017-01-27T08:02:03+00:00

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

2017-01-27T07:55:21+00:00

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.

2016-11-21T18:22:08+00:00

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

2016-11-08T21:38:03+00:00

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.
