[RFC PATCH 0/3] introduce DVFS for GK20A
Hi,
This is a try to have some simple DVFS (Dynamic Voltage and Frequency Scaling)
support for GK20A. Instead of relying on other existing frequency scaling
framework, we create a simple subdev in Nouveau for the same purpose. That's
because we don't want to make the DVFS implementation for GK20A far more
than enough in the beginning and hinder the implementation for dGPU in the
future.

[PATCH V2 1/4] clk: allow non-blocking for nouveau_clock_astate()
There might be some callers of nouveau_clock_astate(), and they are from
inetrrupt context. So we must ensure that this function can be atomic in
that condition. This patch adds one parameter which is subsequently passed
to nouveau_pstate_calc(). Therefore we can choose whether we want to wait
for the pstate work's completion or not.

[PATCH v2 0/15] Falcon library
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
