E.g. one panel needs ACPI video backlight control, +where as the other is using native backlight control. Currently in this case +only one of the 2 required backlight devices will get registered, based on +the acpi_video_get_backlight_type() return value. + +If this (theoretical) case ever shows up, then supporting this will need some +work. A possible solution here would be to pass a device and connector-name +to acpi_video_get_backlight_type() so that it can deal with this. + +Note in a way we already have a case where userspace sees 2 panels, +in dual GPU laptop setups with a mux. On those systems we may see +either 2 native backlight devices; or 2 native backlight devices. + +Userspace already has code to deal with this by detecting if the related +panel is active (iow which way the mux between the GPU and the panels +points) and then uses that backlight device. Userspace here very much +assumes a single panel though. It picks only 1 of the 2 backlight devices +and then only uses that one. + +Note that all userspace code (that I know off) is currently hardcoded +to assume a single panel. + +Before the recent changes to not register multiple (e.g. video + native) +/sys/class/backlight devices for a single panel (on a single GPU laptop), +userspace would see multiple backlight devices all controlling the same +backlight. + +To deal with this userspace had to always picks one preferred device under +/sys/class/backlight and will ignore the others. So to support brightness +control on multiple panels userspace will need to be updated too. + +There are plans to allow brightness control through the KMS API by adding +a "display brightness" property to drm_connector objects for panels. This +solves a number of issues with the /sys/class/backlight API, including not +being able to map a sysfs backlight device to a specific connector. Any +userspace changes to add support for brightness control on devices with +multiple panels really should build on top of this new KMS property. + +Contact: Hans de Goede + +Level: Advanced + Outside DRM =========== diff --git a/MAINTAINERS b/MAINTAINERS index 756e1f532e40..502831824c81 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -1027,6 +1027,13 @@ L: platform-driver-x86@vger.kernel.org S: Maintained F: drivers/platform/x86/amd/pmc.c +AMD PMF DRIVER +M: Shyam Sundar S K <Shyam-sundar.S-k@amd.com> +L: platform-driver-x86@vger.kernel.org +S: Maintained +F: Documentation/ABI/testing/sysfs-amd-pmf +F: drivers/platform/x86/amd/pmf/ + AMD HSMP DRIVER M: Naveen Krishna Chatradhi <naveenkrishna.chatradhi@amd.com> R: Carlos Bilbao <carlos.bilbao@amd.com> @@ -14542,6 +14549,7 @@ M: Daniel Dadap <ddadap@nvidia.com> L: platform-driver-x86@vger.kernel.org S: Supported F: drivers/platform/x86/nvidia-wmi-ec-backlight.c +F: include/linux/platform_data/x86/nvidia-wmi-ec-backlight.h NVM EXPRESS DRIVER M: Keith Busch <kbusch@kernel.org> diff --git a/drivers/acpi/Kconfig b/drivers/acpi/Kconfig index bc9ddd2e3b05..473241b5193f 100644 --- a/drivers/acpi/Kconfig +++ b/drivers/acpi/Kconfig @@ -209,6 +209,7 @@ config ACPI_VIDEO tristate "Video" depends on BACKLIGHT_CLASS_DEVICE depends on INPUT + depends on ACPI_WMI || !X86 select THERMAL help This driver implements the ACPI Extensions For Display Adapters diff --git a/drivers/acpi/acpi_video.c b/drivers/acpi/acpi_video.c index 6d209ea68bd8..32953646caeb 100644 --- a/drivers/acpi/acpi_video.c +++ b/drivers/acpi/acpi_video.c @@ -47,9 +47,6 @@ module_param(brightness_switch_enabled, bool, 0644); static bool allow_duplicates; module_param(allow_duplicates, bool, 0644); -static int disable_backlight_sysfs_if = -1; -module_param(disable_backlight_sysfs_if, int, 0444); - #define REPORT_OUTPUT_KEY_EVENTS 0x01 #define REPORT_BRIGHTNESS_KEY_EVENTS 0x02 static int report_key_events = -1; @@ -73,6 +70,16 @@ module_param(device_id_scheme, bool, 0444); static int only_lcd = -1; module_param(only_lcd, int, 0444); +/* + * Display probing is known to take up to 5 seconds, so delay the fallback + * backlight registration by 5 seconds + 3 seconds for some extra margin. + */ +static int register_backlight_delay = 8; +module_param(register_backlight_delay, int, 0444); +MODULE_PARM_DESC(register_backlight_delay, + "Delay in seconds before doing fallback (non GPU driver triggered) " + "backlight registration, set to 0 to disable."); + static bool may_report_brightness_keys; static int register_count; static DEFINE_MUTEX(register_count_mutex); @@ -81,7 +88,9 @@ static LIST_HEAD(video_bus_head); static int acpi_video_bus_add(struct acpi_device *device); static int acpi_video_bus_remove(struct acpi_device *device); static void acpi_video_bus_notify(struct acpi_device *device, u32 event); -void acpi_video_detect_exit(void); +static void acpi_video_bus_register_backlight_work(struct work_struct *ignored); +static DECLARE_DELAYED_WORK(video_bus_register_backlight_work, + acpi_video_bus_register_backlight_work); /* * Indices in the _BCL method response: the first two items are special, @@ -382,14 +391,6 @@ static int video_set_bqc_offset(const struct dmi_system_id *d) return 0; } -static int video_disable_backlight_sysfs_if( - const struct dmi_system_id *d) -{ - if (disable_backlight_sysfs_if == -1) - disable_backlight_sysfs_if = 1; - return 0; -} - static int video_set_device_id_scheme(const struct dmi_system_id *d) { device_id_scheme = true; @@ -463,56 +464,6 @@ static const struct dmi_system_id video_dmi_table[] = { }, /* - * Some machines have a broken acpi-video interface for brightness - * control, but still need an acpi_video_device_lcd_set_level() call - * on resume to turn the backlight power on.
