similar to: [Bug 98677] New: [NVAC] iMac9, 1 effective backlight brightness range changes after S3

If have a couple patches I found while looking at a panic I was seeing while unloading the nouveau module. Unloading the nouveau module on my optimus notebook machine causes the system to panic. This started occuring when moving from 4.4 to 4.14. These patches make it such that the system does not panic when unloading the module. 4.14 also requires commit 34112bf4935d ("drm/nouveau/fbcon:

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. While we're at it, let's cleanup nouveau_backlight.c as well Lyude Paul (5): drm/nouveau: Check backlight IDs are >= 0, not > 0 drm/nouveau: Move backlight device into

Patches 1-5 are Reviewed-by: Karol Herbst <kherbst at redhat.com> I think it might be worth to test those patches on a system without any backlight devices just to verify we don't break things, but the code looked good already, so maybe we don't really need to test.

Next version of https://patchwork.freedesktop.org/series/48596/ . Added NV_INFO_ONCE and made "Move backlight device into nouveau_connector" use that instead so we don't print the GMUX warning more then once.

Refactor for Ben, hopefully this time this should apply to his tree. Next version of https://patchwork.freedesktop.org/series/48596/ No changes otherwise.

Hi, I found my LCD screen brightness increase when I use firefox and other white background editors and screen brightness decrease when I use dark background applications, such as terminals with black background .? The change in screen brightness depending on the applications has been annoying. My centos version is ver 5.7 64 bit.? Has anyone seen a similar problem or have a solution for

Hi, When using acceleration with Nouveau on MacBook Pros with an 9400M (NVAC) card, a PFIFO interrupt 0x00400000 is thrown during the initialisation of that card (sometime after PFIFO and PGRAPH initialisation) and the laptop will lockup [1], forcing users to load Nouveau without acceleration. After some investigation, I found that enabling bit 1 of register 100c14 fixes the issue on that card.
