[PATCH v5 0/18] Secure Boot refactoring
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

[PATCH v3 00/15] Secure Boot refactoring
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

[PATCH v4 0/33] Secure Boot refactoring / signed PMU firmware support for GM20B
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,

[PATCH] drm/nouveau/secboot/acr: Remove VLA usage
In the quest to remove all stack VLA usage from the kernel[1], this
allocates the working buffers before starting the writing so it won't
abort in the middle. This needs an initial walk of the lists to figure
out how large the buffer should be.

[PATCH v3 00/11] nouveau: add secure boot support for dGPU and Tegra
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.

[PATCH v2 0/5] nouveau: add secure boot support for dGPU and Tegra
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

[PATCH] secboot/acr352: reset PMU after secboot
This is needed for using Nouveaus PMU image after performing secboot. This will
be helpfull for Maxwell2 reclocking on boards without externally controlled
fans like on most laptops or fanless boards.

This was the first step of the secure boot refactoring - as Ben asked for some

Nouveau: kernel hang on Optimus+Intel+NVidia GeForce 1060m
Hi,
the system fails to initialize your vbios using secureboot (i had a rare
chance to on my system to witness it again), for now i traced it to
acr_boot_falcon() in
"linux/drivers/gpu/drm/nouveau/nvkm/falcon/msgqueue_0148cdec.c" where it
throws -110 which is -ETIMEDOUT. You could try to increase the timeout
and see if it helps something, similar to the following:

[PATCH 0/4] secboot: be more resilient on errors
This series fixes two cases where behavior on secure boot errors could be
improved:
1) Patch 2 propages secure-boot errors from GR init, making sure initialization
fails as it should. Failure to do so results in a black screen during boot,
as reported in FD bug 94990.
2) Patches 3-4 make the absence of required secure firmware files a non-fatal
error. The previous behavior was to give up

[PATCH 00/11] drm/nouveau: Enable GP10B by default
From: Thierry Reding <treding at nvidia.com>
Hi,
the GPU on Jetson TX2 (GP10B) does not work properly on all devices. Why
exactly is not clear, but there are slight differences between the SKUs
that were tested. It turns out that the biggest issue is that on some
devices (e.g. the one that I have), pulsing the GPU reset twice as is
done in the current code (once as part of the power-ungate

[PATCH v3 0/9] drm/nouveau: Various fixes for GP10B
From: Thierry Reding <treding at nvidia.com>
Hi Ben,
here's a revised subset of the patches I had sent out a couple of weeks
ago. I've reworked the BAR2 accesses in the way that you had suggested,
which at least for GP10B turned out to be fairly trivial to do. I have
not looked in detail at this for GV11B yet, but a cursory look showed
that BAR2 is accessed in more places, so the
