Two trivial PMU-related fixes for Tegra: - Add a dummy func member to GK20A, since nvkm_pmmu_pgob() unconditionally dereferences it - Check whether a PMU actually exists before calling nvkm_pmmu_pgob(). During early bringup we are likely to not have a PMU Alexandre Courbot (2): pmu/gk20a: add dummy func gr/gf100: do not assume a PMU is present drm/nouveau/nvkm/engine/gr/gf100.c | 3 ++-

nvkm_mm_fini() was not called when exiting the driver, resulting in a memory leak. Fix this.

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.

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.

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
