Hi everyone, Apologies for the big patchset. This is a rework of the secure boot code that moves the building of the blob into its own set of source files (and own hooks), making the code more flexible and (hopefully) easier to understand as well. This rework is needed to support more signed firmware for existing and new chips. Since the firmwares in question are not available yet I cannot send

Sending things in a smaller chunks since it makes their reviewing easier. This part part 2/3 of the secboot refactoring/PMU command support patch series. Part 1 was the new falcon library which should be merged soon now. This series is mainly a refactoring/sanitization of the existing secure boot code. It does not add new features (part 3 will). Secure boot handling is now separated by NVIDIA

This is a highly changed revision of the first patch series that adds secure boot support to Nouveau. This code still depends on NVIDIA releasing official firmware files, but the files released with SHIELD TV and Pixel C can already be used on a Jetson TX1. As you know we are working hard to release the official firmware files, however in the meantime it doesn't hurt to review the code so it

This revision includes initial signed PMU firmware support for GM20B (Tegra X1). This PMU code will also be used as a basis for dGPU signed PMU firmware support. With the PMU code, the refactoring of secure boot should also make more sense. ACR (secure boot) support is now separated by the driver version it originates from. This separation allows to run any version of the ACR on any chip,

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

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
