...reen. I then suspend to ram via the /sys/power/state interface. Upon resuming the backlight appears to be at 100 percent. If I set the brightness to values such as 30 and 60 the screen remains dark. It is barely visible as a flicker at 70. At 100 it is visible. I've observed that the value of NV50_PDISP_SOR_PWM_DIV (0x0061c080) is 0x1 after a boot but is set to 0x84 after a resume. It appears there's an init script in the bios dump which sets it to the value of 0x84. I have confirmed if I use the nouveau option nouveau.config=NvForcePost=1 that the behavior after booting is the same as after a resume. The...

Next version of https://patchwork.freedesktop.org/series/48596/ . Made some important changes to the refactoring patch, but everything else is the same.

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

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. Lyude Paul (5): drm/nouveau: Add NV_PRINTK_ONCE and variants drm/nouveau: Move backlight device into nouveau_connector drm/nouveau:

Forgot to send 6 patches instead of five since there's one new one now, whoops! No actual changes, next version of https://patchwork.freedesktop.org/series/48596/ Lyude Paul (6): drm/nouveau: Check backlight IDs are >= 0, not > 0 drm/nouveau: Add NV_PRINTK_ONCE and variants drm/nouveau: Move backlight device into nouveau_connector drm/nouveau:

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