* drm/i915/display: Increase Fast Wake Sync length as a quirkJouni Högander2024-09-031-0/+17
| | | | | | | | | | | | | | | | | | | | In commit "drm/i915/display: Increase number of fast wake precharge pulses" we were increasing Fast Wake sync pulse length to fix problems observed on Dell Precision 5490 laptop with AUO panel. Later we have observed this is causing problems on other panels. Fix these problems by increasing Fast Wake sync pulse length as a quirk applied for Dell Precision 5490 with problematic panel.

* drm/i915/display: Add mechanism to use sink model when applying quirkJouni Högander2024-09-031-0/+51
| | | | | | | | | | | | | | | | | | | Currently there is no way to apply quirk on device only if certain panel model is installed. This patch implements such mechanism by adding new quirk type intel_dpcd_quirk which contains also sink_oui and sink_device_id fields and using also them to figure out if applying quirk is needed. New intel_init_dpcd_quirks is added and called after drm_dp_read_desc with proper sink device identity read from dpcdc. v3: - !mem_is_zero fixed to mem_is_zero v2: - instead of using struct intel_quirk add new struct intel_dpcd_quirk Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240902064241.1020965-2-jouni.hogander@intel.com

* drm/i915: keep backlight_enable on until turn eDP display offLee Shawn C2021-06-241-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This workaround is specific for a particular panel on Google chromebook project. When user space daemon enter idle state. It request adjust brightness to 0, turn backlight_enable signal off and keep eDP main link active. On general LCD, this behavior might not be a problem. But on this panel, its tcon would expect source to execute full eDP power off sequence after drop backlight_enable signal. Without eDP power off sequence. Even source try to turn backlight_enable signal on and restore proper brightness level. This panel is not able to light on again. This WA ignored the request from user space daemon to disable backlight_enable signal and keep it on always. When user space request kernel to turn eDP display off, kernel driver still can control backlight_enable signal properly. It would not impact standard eDP power off sequence. v2: 1. modify the quirk name and debug messages. 2. unregister backlight.power callback for specific device. v3: 1. modify debug output messages. 2. use DMI_EXACT_MATCH instead of DMI_MATCH.

* drm/i915: Add invert-brightness quirk for Thundersoft TST178 tabletHans de Goede2020-03-041-0/+10
| | | | | | | | | | | | | | | | | | The Thundersoft TST178 tablet uses a DSI panel with an external PWM controller (as all DSI panels do). But unlike other DSI panels a duty-cycle of 100% turns the backlight off and 0% sets it to maximum brightness. I've checked the VBT and there is a BDB_LVDS_BACKLIGHT section, but it does not set the active_low_pwm flag. This tablet re-uses the main PCI vendor and product ids for the subsystem ids, so I see no other option then to add a DMI based quirk to fix this. Note that the PWM backlight code in intel_panel.c currently does not honor the vbt.active_low_pwm flag, but that does not matter in this case.
