drm/nouveau: add missing DCB connector types

2026-01-21T20:47:40Z

* Add missing DCB connectors in conn.h as per the NVIDIA DCB specification. A lot of connector logic was rewritten for Linux v6.5; some display connector types went unaccounted-for which caused kernel warnings on devices with the now-unsupported DCB connectors. This patch adds all of the DCB connectors as defined by NVIDIA to the dcb_connector_type enum to bring back support for these connectors to the new logic.

drm/nouveau/disp: add output class

2022-07-26T23:05:49Z

Will be used to more cleanly implement existing method interfaces that take some confusing (IEDTkey, inherited from VBIOS, which RM no longer uses on Ampere) match values to determine which display path to operate on. Methods will be protected from racing with supervisor, and from being called where they shouldn't be (ie. without an OR assigned). v2: - use ?: (lyude) v3: - fix return code if noacquire() method fails Signed-off-by: Ben Skeggs Signed-off-by: Dave Airlie

drm/nouveau/kms: handle mDP connectors

2021-01-29T06:49:15Z

In some cases we have the handle those explicitly as the fallback connector type detection fails and marks those as eDP connectors. Attempting to use such a connector with mutter leads to a crash of mutter as it ends up with two eDP displays. Information is taken from the official DCB documentation.

drm/nouveau/gpio: check function 76 in the power check as well

2019-08-23T02:55:34Z

Added GPIO is "Power Alert". It's uncertain if this GPIO is set on GPU initialization or only if a change is detected by the GPU at runtime. This GPIO can be found on Tesla and sometimes on Fermi GPUs. Untested, wrote according to documentation. Signed-off-by: Mark Menzynski Signed-off-by: Ben Skeggs

drm/nouveau/gpio: check the gpio function 16 in the power check as well

2019-08-23T02:55:33Z

Added GPIO is "Thermal and External Power Detect". It's uncertain if this GPIO is set on GPU initialization or only if a change is detected by the GPU at runtime. This GPIO can be found in Rankine and Curie and rarely on Tesla GPUs VBIOS. Untested, wrote according to documentation. Signed-off-by: Mark Menzynski Signed-off-by: Ben Skeggs

drm/nouveau/gpio: fail if gpu external power is missing

2019-08-23T02:55:33Z

Currently, nouveau doesn't check if GPU is missing power. This patch makes nouveau fail when this happens on latest GPUs. It checks GPIO function 121 (External Power Emergency), which should detect power problems on GPU initialization. This can be disabled with nouveau.config=NvPowerChecks=1 Tested on TU104, GP106 and GF100. v3: * Add config override for disabling power checks Signed-off-by: Mark Menzynski Signed-off-by: Ben Skeggs

drm/nouveau/therm: skip probing for devices not specified in thermal tables

2019-08-23T02:55:33Z

Saves some time during driver load, as described by the relevant section[1] of the DCB 4.x specification. [1] https://nvidia.github.io/open-gpu-doc/DCB/DCB-4.x-Specification.html#_i2c_device_table Signed-off-by: Ben Skeggs

drm/nouveau: fix bogus GPL-2 license header

2019-07-19T06:26:50Z

The bulk SPDX addition made all these files into GPL-2.0 licensed files. However the remainder of the project is MIT-licensed, these files (primarily header files) were simply missing the boiler plate and got caught up in the global update.
