device (un)registration - notification - -Some firmware drivers, ie acpi-video want to get themselves out of the -way (in some cases) when their also is a raw backlight device available. - -Due to module loading ordering being unknown, acpi-video cannot be certain -that the backlight_device_registered(BACKLIGHT_RAW) it does for this is -the final verdict wrt there being a BACKLIGHT_RAW device. - -By adding notification acpi-video can listen for backlight devices showing -up after it has loaded, and unregister its backlight device if desired. - -Signed-off-by: Hans de Goede

before registering backlight - -acpi_video_backlight_support() is supposed to be called by other (vendor -specific) firmware backlight controls, not by native / raw backlight controls -like nv_backlight. - -Userspace will normally prefer firmware interfaces over raw interfaces, so -if acpi_video backlight support is present it will use that even if -nv_backlight is registered as well. - -Except when video.use_native_backlight is present on the kernel cmdline -(or enabled through a dmi based quirk). As the name indicates the goal here -is to make only the raw interface available to userspace so that it will use -that (it only does this when it sees a win8 compliant bios). - -This is done by: -1) Not registering any acpi_video# backlight devices; and -2) Making acpi_video_backlight_support() return true so that other firmware -drivers, ie acer_wmi, thinkpad_acpi, dell_laptop, etc. Don't register their -own vender specific interfaces. - -Currently nouveau breaks this setup, as when acpi_video_backlight_support() -returns true, it does not register itself, resulting in no backlight control -at all. - -This is esp. going to be a problem with 3.16 which will default to -video.use_native_backlight=1, and thus nouveau based laptops with a win8 bios -will get no backlight control at all. - -This also likely explains why the previous attempt to make -video.use_native_backlight=1 the default was not a success, as without this -patch having a default of video.use_native_backlight=1 will cause regressions. - -Note this effectively reverts commit 5bead799 - -Also see: https://bugzilla.redhat.com/show_bug.cgi?id=1093171 - -Signed-off-by: Hans de Goede <hdegoede@redhat.com> ---- - drivers/gpu/drm/nouveau/nouveau_backlight.c | 9 --------- - 1 file changed, 9 deletions(-) - -diff --git a/drivers/gpu/drm/nouveau/nouveau_backlight.c b/drivers/gpu/drm/nouveau/nouveau_backlight.c -index 630f6e84fc01..2c1e4aad7da3 100644 ---- a/drivers/gpu/drm/nouveau/nouveau_backlight.c -+++ b/drivers/gpu/drm/nouveau/nouveau_backlight.c -@@ -31,7 +31,6 @@ - */ - - #include <linux/backlight.h> --#include <linux/acpi.h> - - #include "nouveau_drm.h" - #include "nouveau_reg.h" -@@ -222,14 +221,6 @@ nouveau_backlight_init(struct drm_device *dev) - struct nouveau_device *device = nv_device(drm->device);
