2023-09-19drm/nouveau/kms: Add INHERIT ioctl to nvkm/nvif for reading IOR stateLyude Paul
Now that we're supporting things like Ada and the GSP, there's situations where we really need to actually know the display state that we're starting with when loading the driver in order to prevent breaking GSP expectations. The first step in doing this is making it so that we can read the current state of IORs from nvkm in DRM, so that we can fill in said into into the atomic state. We do this by introducing an INHERIT ioctl to nvkm/nvif. This is basically another form of ACQUIRE, except that it will only acquire the given output path for userspace if it's already set up in hardware. This way, we can go through and probe each outp object we have in DRM in order to figure out the current hardware state of each one. If the outp isn't in use, it simply returns -ENODEV. This is also part of the work that will be required for implementing GSP support for display. While the GSP should mostly work without this commit, this commit should fix some edge case bugs that can occur on initial driver load. This also paves the way for some of the initial groundwork for fastboot support.

2023-08-03drm/nouveau/nvkm/dp: Add workaround to fix DP 1.3+ DPCD issuesLyude Paul
Currently we use the drm_dp_dpcd_read_caps() helper in the DRM side of nouveau in order to read the DPCD of a DP connector, which makes sure we do the right thing and also check for extended DPCD caps. However, it turns out we're not currently doing this on the nvkm side since we don't have access to the drm_dp_aux structure there - which means that the DRM side of the driver and the NVKM side can end up with different DPCD capabilities for the same connector. Ideally in order to fix this, we just want to use the drm_dp_read_dpcd_caps() helper in nouveau. That's not currently possible though, and is going to depend on having a bunch of the DP code moved out of nvkm and into the DRM side of things as part of the GSP enablement work. Until then however, let's workaround this problem by porting a copy of drm_dp_read_dpcd_caps() into NVKM - which should fix this issue.

2023-08-03drm/nouveau/gr: enable memory loads on helper invocation on all channelsKarol Herbst
We have a lurking bug where Fragment Shader Helper Invocations can't load from memory. But this is actually required in OpenGL and is causing random hangs or failures in random shaders. It is unknown how widespread this issue is, but shaders hitting this can end up with infinite loops. We enable those only on all Kepler and newer GPUs where we use our own Firmware. Nvidia's firmware provides a way to set a kernelspace controlled list of mmio registers in the gr space from push buffers via MME macros. v2: drop code for gm200 and newer.

2023-07-06drm/nouveau/fifo/ga100-: remove individual runlists rather than failing oneinitBen Skeggs
We're adding better support for the non-stall interrupt, which will need to fetch the interrupt vector from the runlist's primary engine. NVKM doesn't support all target engines (ie. NVDEC etc), and it wouldn't be ideal to completely fail initialisation in this case. Instead. Remove runlists where we can't determine all the needed info.

2023-07-06drm/nouveau/nvkm: fini object children in reverse orderBen Skeggs
Turns out, we're currently tearing down the disp core channel *before* the satellite channels (wndw, etc) during suspend. This makes RM return NV_ERR_NOT_SUPPORTED on attempting to reallocate the core channel on resume for some reason, but we probably shouldn't be doing it on HW either. Tear down children in the reverse of allocation order instead.
