Look for firmware files using the legacy ("nouveau/nvxx_fucxxxx") path if they cannot be found in the new, "official" path. User setups were broken by the switch, which is bad. There are only 4 firmware files we may want to look up that way, so hardcode them into the lookup function. All new firmware files should use the standard "nvidia/<chip>/gr/" path.

Hello everyone, GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support for it, based on a rework of the already-supported GK20A. It also introduces support for NVIDIA-provided firmware files, which is why I have added a few NVIDIA people who are relevant to this discussion. The first patch adds support for loading the FECS and GPCCS firmwares from firmware files

Second version of this patchset. Not many changes since first version - I hope this means the changes are not too controversial. Changes since v1: - Removed lookup for previous FW files in "nouveau/" - Went back to using request_firmware() since we only try to load one file Original cover letter follows: GM20B is the GPU of the upcoming Tegra X1 SoC. This series adds initial support

This patchset centralizes the firmware-loading procedure to one set of functions instead of having each engine load its firmware as it pleases. This helps ensure that all firmware comes from the same place, namely nvidia/<chip>/. This changes where the firmware is fetched from for falcon/xtensa/bios, but these locations never seemed to have been official anyway. Also for most (all?) chips

New version of the secure boot code that works with the blobs just merged into linux-firmware. Since the required Mesa patches are also merged, this set is the last piece of the puzzle to get out-of-the-box accelerated Maxwell 2. The basic code remains the same, with a few improvements with respect to how secure falcons are started. Hopefully the patchset is better split too. I have a

I wonder if perhaps we should just replace the mechanism entirely, and remove the support for nouveau/fuc* as we add

The following functions are not declared outside of the file they are in, so make them static to avoid these warnings: drivers/gpu/drm/nouveau/nvkm/engine/gr/gf100.c:745:1: warning: symbol 'gf100_gr_fecs_start_ctxsw' was not declared. Should it be static? drivers/gpu/drm/nouveau/nvkm/engine/gr/gf100.c:760:1: warning: symbol 'gf100_gr_fecs_stop_ctxsw' was not declared. Should it be

This was the first step of the secure boot refactoring - as Ben asked for some fixes, I now submit it as its own series to make it easier to review (and also because rebasing secure boot on top of this takes time and I don't want to do it until this is validated!). This series attempts to factorize the duplicate falcon-related code into a single library, using the existing nvkm_falcon

this series makes use of the load counters we can use to get information about the current load of the gpu. This series includes the needed pmu bits and a debugfs interface to read them out. Currently the values are between 0 and 255, because it is much easier to implement it this way on the pmu. Karol Herbst (4): subdev/pmu/fuc: add gk104 pmu/fuc: add macros for pdaemon pwr counters

these are usually used for dynamic reclocking on gt215 and newer The counters are used to get the load of the core, memory, video and pcie loads currently I expose the loads through a debugfs "current_load" file, but I want to move that to nvif and just add a wrapper around that in debugfs for convenience. Using nvif would have the advantage, that userspace tools can easily get loads

I think I am done reworking the series and getting to a point where I think it is basically finished. The configuration of the slots could be improved later on when working on dynamic reclocking, but for now it's good enough to report the current GPU utilization to userspace. Patches 1-4 imeplement PMU commands to setup and readout the counters. Patches 5-6 lets Nouveau make use of 1-4. Patch

reworked this series quite a lot. Now we want the Host to configure the counters through the PMU. The series isn't complete though because it needs: 1. reordering 2. better commit messages but I felt like sending those out before doing a final version. I also found some weird register overwriting issue on the PMU I have to track down, because it interfers with the counter read out. I am

The code would print a NULL string if no legacy firmware was found.
