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, devicekit need standardise i/o... I've

Straight port of Matthias Hopf's KMS backlight code for xf86-video-intel, with reformatting and a couple of minor cleanups. Works fine on my MacBookAir2,1.

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 backlight can then be controlled via

Macbook 5,1 with MCP79 lost its backlight control since the recent change for supporting GFP-RM; it rewrote the whole nv50 backlight control code and each display engine is supposed to have an entry for IOR bl callback, but it didn't cover mcp77. This patch adds the missing bl entry initialization for mcp77 display engine to recover the backlight control. Fixes: 2274ce7e3681

Hi, I wrote a patch for nouveau_backlight.c to support the backlight control of the GT 525M. Only the case NV_C0: is needed to get the backlight control with my NVC0 card working. I don't think that it's worth to add new functions for c0 if the old ones still work. This is my first patch for the Linux kernel.

The nouveau code used to call drm_fb_helper_initial_config() from nouveau_fbcon_init() before calling drm_dev_register(). This would probe all connectors so that drm_connector->status could be used during backlight registration which runs from nouveau_connector_late_register(). After commit 4a16dd9d18a0 ("drm/nouveau/kms: switch to drm fbdev helpers") the fbdev emulation code, which

Hi Guys Sorry, I've been away for a few days. As the backlight is an iterative process I thought I'd get some feedback before I move to the next stage:- The colour of the backlight:- I think blue would work best? On/Off Status, I've put some thought into this and think the light should come on in the following circumstances:- Phone Rings Phone handset is picked up Speaker
