Backlights controlled by i915.ko and only associated with its connectors and also only associated with the intel_drmfb fbcon, controlled by i915.ko. In this situation, we already handle adjusting the backlight when the fbcon is blanked/unblanked and do not require backlight trying to do the same. Attempting...

Hi, I'm trying to bring devs to support for backlight on nv50 cards for above 1 year, without any success A lot of laptop (from mac, hp, samsung) doesn't have laptop_panel in hal, and therefore no support for acpi/backlight..., and no entry in /proc/acpi/video nor /sys/class/backlight Kernel team is not reacting, hal team won't fix, device...

Currently, every backlight interface created by Nouveau uses the same name, nv_backlight. This leads to a sysfs warning as it tries to create an already existing folder. This patch adds a incremented number to the name, but keeps the initial name as nv_backlight, to avoid possibly breaking userspace; the second interface wil...

Hi I've taken apart a 7960 to fit a backlight to the LCD. Would others on the list be interested in this as a project when I've finished (i.e. should I document and photo all the stages)? Also I can source some 7960's at a very good price but what are the rules about posting this information on the list if others were interested? P

The Apple GMUX is the one managing the backlight, so there is no need for Nouveau to register its own backlight interface.

Remove unnecessary dependencies in the include statements of the header file <linux/fb.h>. Several files throughout the kernel include the fbdev header, so reducing dependencies positively affects other subsystems as well. Also fix up corgi-lcd, nouveau and fbtft, which need backlight.h in some of their source files. v3: * include backlight.h in corgi-lcd (kernel test robot) * grammar fixes in commit messages v2: * include backlight.h in fbtft (kernel test robot) Thomas Zimmermann (9): backlight/corgi-lcd: Include <linux/backlight.h> drm/nouveau: Include <linux...

Several nvidia-based systems don't support backlight control via the standard ACPI control mechanisms. Instead, it's necessary for the driver to modify the backlight control registers directly. This patch adds support for determining whether the registers appear to be in use, and if so registers a kernel backlight device to control them. The...

This series fixes some issues with nouveau's backlight support that were causing kernel panics on module reloads, specifically on systems with nouveau handling the backlight of one of the displays.
