I only get pieces in my inbox which is mildly annoying on my end. Looks like we are getting close here. One procedural question I have, do you have commit permissions to drm-misc? I applied the series to drm-misc-next and tried to build.

The command is simple: make -j20 The system details, incase it somehow matters: Ubuntu 22.04 w/ 5.15 kernel $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 22.04.3 LTS Release: 22.04 Codename: jammy $ uname -a Linux jhugo-lnx 5.15.0-89-generic #99-Ubuntu SMP Mon Oct 30 20:42:41 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux The kernel config is probably the relevant piece. When I first built after applying the series, I was asked to choose what to do with the new config item.

I beleive the comments in the checkpatch.pl script are fairly straightforward. I use a copy of the database from the github that is rather recent. The Ubuntu distro package is really out of date and I don't think I looked to see if there is a pythong pip version. Grabbing the one file from the github repo seemed simple emough. -Jeff
This patchset introduces a new Linux Kernel Driver, amdxdna for AMD NPUs. The driver is based on Linux accel subsystem. NPU (Neural Processing Unit) is an AI inference accelerator integrated into AMD client CPUs. NPU enables efficient execution of Machine Learning applications like CNNs, LLMs, etc. NPU is based on AMD XDNA architecture [1]. AMD NPU consists of the following components: - Tiled array of AMD AI Engine processors. - Micro Controller which runs the NPU Firmware responsible for command processing, AIE array configuration, and execution management. - PCI EP for host control of the NPU device. - Interconnect for connecting the NPU components together. - SRAM for use by the NPU Firmware. - Address translation hardware for protected host memory access by the NPU. NPU supports multiple concurrent fully isolated contexts. Concurrent contexts may be bound to AI Engine array spatially and or temporarily. The driver is licensed under GPL-2.0 except for UAPI header which is licensed GPL-2.0 WITH Linux-syscall-note. User mode driver stack consists of XRT [2] and AMD AIE Plugin for IREE [3]. The firmware for the NPU is distributed as a closed source binary, and has already been pushed to the DRM firmware repository [4].
