[PATCH 2/4] drm/probe-helper: add drm_kms_helper_connector_hotplug_event
by Simon Ser 09 Jun '21

09 Jun '21

This function is the same as drm_kms_helper_hotplug_event, but takes a connector instead of a device.

[PATCH] drm/mcde: Fix off by 10^3 in calculation
by Linus Walleij 09 Jun '21

09 Jun '21

The calclulation of how many bytes we stuff into the DSI pipeline for video mode panels is off by three orders of magnitude because we did not account for the fact that the DRM mode clock is in kilohertz rather than hertz. This used to be: drm_mode_vrefresh(mode) * mode->htotal * mode->vtotal which would become for example for s6e63m0: 60 x 514 x 831 = 25628040 Hz, but mode->clock is 25628 as it is in kHz. This affects only the Samsung GT-I8190 "Golden" phone right now since it is the only MCDE device with a video mode display. Curiously some specimen work with this code and wild settings in the EOL and empty packets at the end of the display, but I have noticed an eeire flicker until now. Others were not so lucky and got black screens.
