Subject: [PATCH 6/6] ply-device-manager: Also ignore SimpleDRM devs in
|
|
coldplug enumeration path
|
|
|
|
Plymouth has 2 hw discovery paths:
|
|
1. Enumerating devices already known by udev at plymouth startup
|
|
2. Devices which are hotplugged after startup
|
|
|
|
At boot we have udevd which is enumerating hw and plymouthd racing
|
|
with each other, which means that plymouthd may discover the new
|
|
SimpleDRM device through either 1. or 2.
|
|
|
|
Before this patch a check for SimpleDRM was missing from path 1, causing
|
|
it to be treated as a normal device instead of being ignored as intended:
|
|
|
|
plymouth-debug.log for the simpledrm being enumerated in path 1:
|
|
|
|
ply-device-manager.c:344: create_devices_for_subsystem:
|
|
found device /sys/devices/platform/simple-framebuffer.0/drm/card0
|
|
ply-device-manager.c:351: create_devices_for_subsystem:
|
|
device is initialized
|
|
ply-device-manager.c:360: create_devices_for_subsystem:
|
|
found node /dev/dri/card0
|
|
ply-device-manager.c:283: create_devices_for_udev_device:
|
|
found DRM device /dev/dri/card0
|
|
ply-device-manager.c:885: create_devices_for_terminal_and_rende:
|
|
creating devices for /dev/dri/card0 (renderer type: 1)
|
|
|
|
plymouth-debug.log for the simpledrm *not* being enumerated in path 1:
|
|
|
|
ply-device-manager.c:344: create_devices_for_subsystem:
|
|
found device /sys/devices/platform/simple-framebuffer.0/drm/card0
|
|
ply-device-manager.c:367: create_devices_for_subsystem:
|
|
it's not initialized
|
|
|
|
followed by path 2 enumerating the device very shortly after this:
|
|
|
|
ply-device-manager.c:532: on_udev_event:
|
|
got add event for device /dev/dri/card0
|
|
ply-device-manager.c:462: verify_add_or_change:
|
|
ignoring since we only handle SimpleDRM devices after timeout
|
|
|
|
Note how path 2 does correctly ignore SimpleDRM devices, where as
|
|
path 1 does not. This commit fixes this by moving the verify_drm_device()
|
|
check in to create_devices_for_udev_device() which runs in both paths.
