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!

From: Pierre Moreau <pierre.morrow at free.fr> 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 will be named

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

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

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 will be named nv_backlight1, and so on.

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

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:
