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 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 the code to manage then, but hopefully the

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,

Hi, I've been checking out NUT with an OpenUPS board over the last couple of weekends, and have noticed that it doesn't seem to report sensible values. This lead me to investigate usbhid-ups and delve into various issues. As mentioned in a github issue, one of the problems is with the report descriptor - dumping this from the usbhid-ups debug output and picking through it reveals that

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

XDP socket(AF_XDP) is an excellent bypass kernel network framework. The zero copy feature of xsk (XDP socket) needs to be supported by the driver. The performance of zero copy is very good.

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

Hi Vinod, Bjorn, Patrice, This patchset adds support for the Flexible Direct Memory Access (FDMA) core found on STi chipsets from STMicroelectronics. The FDMA is a slim core CPU with a dedicated firmware. It is a general purpose DMA controller supporting 16 independent channels and data can be moved from memory to memory or between memory and paced latency critical real time targets. After quite
