4 years agodrm/nouveau/acr: implement new subdev to replace "secure boot"

drm/nouveau/acr: implement new subdev to replace "secure boot"

ACR is responsible for managing the firmware for LS (Low Secure) falcons,
this was previously handled in the driver by SECBOOT.

This rewrite started from some test code that attempted to replicate the
procedure RM uses in order to debug early Turing ACR firmwares that were
provided by NVIDIA for development.

Compared with SECBOOT, the code is structured into more individual steps,
with the aim of making the process easier to follow/debug, whilst making
it possible to support newer firmware versions that may have a different
binary format or API interface.

The HS (High Secure) binary(s) are now booted earlier in device init, to
match the behaviour of RM, whereas SECBOOT would delay this until we try
to boot the first LS falcon.

There's also additional debugging features available, with the intention
of making it easier to solve issues during FW/HW bring-up in the future.

drm/nouveau/mmu: Add correct turing page kinds

Turing introduced a new simplified page kind
scheme, reducing the number of possible page
kinds from 256 to 16.  It also is the first
NVIDIA GPU in which the highest possible page
kind value is not reserved as an "invalid" page
kind.

To address this, the invalid page kind is made
an explicit property of the MMU HAL, and a new
table of page kinds is added to the tu102 MMU
HAL.

One hardware change not addressed here is that
0x00 is technically no longer a supported page
kind, and pitch surfaces are instead intended to
share the block-linear generic page kind 0x06.
However, because that will be a rather invasive
change to nouveau and 0x00 still works fine in
practice on Turing hardware, addressing this new
behavior is deferred.

that initializing newer GPUs after older GPUs

drm/nouveau/tegra: Avoid pulsing reset twice

When the GPU powergate is controlled by a generic power domain provider,
the reset will automatically be asserted and deasserted as part of the
power-ungating procedure.

On some Jetson TX2 boards, doing an additional assert and deassert of
the GPU outside of the power-ungate procedure can cause the GPU to go
into a bad state where the memory interface can no longer access system
memory.

drm/nouveau/kms/nv50-: Report possible_crtcs incorrectly on mstos, for now

This commit is seperate from the previous one to make it easier to
revert in the future. Basically, while working on making MSTOs per-head
as opposed to per-head-per-connector I discovered these lovely issues:

https://gitlab.freedesktop.org/xorg/xserver/merge_requests/277
https://gitlab.gnome.org/GNOME/mutter/issues/759

Note as well that Intel already has a temporary workaround for this in
their kernel driver. So, unfortunately we need to follow suit to avoid
causing a regression in userspace. Once these issues get fixed, this
commit should be reverted.

4 years agodrm/nouveau/kms/nv50-: Use less encoders by making mstos per-head

drm/nouveau/kms/nv50-: Use less encoders by making mstos per-head

Currently, for every single MST capable DRM connector we create a set of
fake encoders, one for each possible head. Unfortunately this ends up
being a huge waste of encoders. While this currently isn't causing us
any problems, it's extremely close to doing so.

The ThinkPad P71 is a good example of this. Originally when trying to
figure out why nouveau was failing to load on this laptop, I discovered
it was because nouveau was creating too many encoders. This ended up
being because we were mistakenly creating MST encoders for the eDP port,
however we are still extremely close to hitting the encoder limit on
this machine as it exposes 1 eDP port and 5 DP ports, resulting in 31
encoders.

So while this fix didn't end up being necessary to fix the P71, we still
need to implement this so that we avoid hitting the encoder limit for
valid display configurations in the event that some machine with more
connectors then this becomes available. Plus, we don't want to let good
code go to waste :)

So, use less encoders by only creating one MSTO per head. Then, attach
each new MSTC to each MSTO which corresponds to a head that it's parent
DP port is capable of using. This brings the number of encoders we
register on the ThinkPad P71 from 31, down to just 15. Yay!

drm/nouveau/kms/nv50-: Remove nv50_mstc_best_encoder()

When drm_connector_helper_funcs->atomic_best_encoder is defined,
->best_encoder is ignored by the atomic modesetting helpers. That being
said, this hook is completely broken anyway - it always returns the
first msto for a given mstc, despite the fact it might already be in
use.

So, just get rid of it. We'll need this in a moment anyway, when we make
mstos per-head as opposed to per-connector.
