- NONE: The fan is never touched (default)
- MANUAL: The fan is set to the user-defined fan speed (pwm1)
This patch introduces a distinction between ptherm internal fan management

while the first can still select the speed it wants unless the NONE mode
is selected. This is important for automatic fan management.

drm/nouveau/core: pull in most of the new core infrastructure
This commit provides most of the infrastructure to support a major overhaul
of Nouveau's internals coming in the following commits. This work aims to
take all the things we've learned over the last several years, and turn that
into a cleaner architecture that's more maintainable going forward.
RAMHT and MM bits of the new core have been left out for the moment, and
will be pulled in as I go through the process of porting the code to
become either subdev or engine modules.
There are several main goals I wanted to achieve through this work:
-- Reduce complexity
The goal here was to make each component of the driver as independent as
possible, which will ease maintainability and readability, and provide a
good base for resetting locked up GPU units in the future.
-- Better tracking of GPU units that are required at any given time
This is for future PM work, we'll be able to tell exactly what parts of the
GPU we need powered at any given point (etc).
-- Expose all available NVIDIA GPUs to the client
In order to support things such as multi-GPU channels, we want to be able
to expose all the NVIDIA GPUs to the client over a single file descriptor
so it can send a single push buffer to multiple GPUs.
-- Untangle the core hardware support code from the DRM implementation
This happened initially as an unexpected side-effect of developing the
initial core infrastructure in userspace, but it turned into a goal of
the whole project. Initial benefits will be the availablility of a
number of userspace tools and tests using the same code as the driver
itself, but will also be important as I look into some virtualisation
ideas.
