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.

drm/nouveau/kms/nv50-: determine MST support from DP Info Table

GV100 doesn't support MST, use the information provided in VBIOS tables to detect its presence instead. Signed-off-by: Ben Skeggs
