Patch series addresses a shortcoming where we're sending a hot plug event without passing the actual CONNECTOR that caused it. This takes into consideration both the polling path and the HPD (Hot Plug Detect) path.
v4: - removed the "This patch" bit - Dmitry - added a short note when the flag is set and cleared - Dmitry - address double dead-locking detected - kbot: https://lore.kernel.org/dri-devel/[email protected]/ - virtual connectors do not seem have any kind of hotplug - added polling in vkms - as noted by Ian v3: Address comments from Dmitry - guard connector status write with mode_config.mutex - avoid setting up the connector status and immediately unset it. Do the unset in drm_kms_helper_hotplug_event/drm_kms_helper_connector_hotplug_event - v3 is at https://lore.kernel.org/dri-devel/[email protected]/ v2: Address comments from Daniel - split patch into 2, one that introduces a bool to track connector connection status change and a patch that uses that to be able to send hot plug events with the proper CONNECTOR ID to udev and further pass that down to user-space - nuke out mutex when iterating connector list - fix typo - v2 is at https://lore.kernel.org/dri-devel/[email protected]/ Marius Vlad (3): drm: Introduce a new connector status drm: Propagate connector status change drm/vkms: Add polling for HPD drivers/gpu/drm/drm_connector.c | 1 + drivers/gpu/drm/drm_probe_helper.c | 39 ++++++++++++++++++++++++++---- drivers/gpu/drm/drm_sysfs.c | 1 + drivers/gpu/drm/vkms/vkms_drv.c | 4 +++ include/drm/drm_connector.h | 3 +++ 5 files changed, 43 insertions(+), 5 deletions(-) -- 2.47.2
