I -thought- I had fixed this entirely, but it looks like that I didn't
test this thoroughly enough as we apparently still make one big mistake
with nv50_msto_atomic_check() - we don't handle the following scenario:
* CRTC #1 has n VCPI allocated to it, is attached to connector DP-4
which is attached to encoder #1. enabled=y active=n
* CRTC #1 is changed from DP-4 to DP-5, causing:
* DP-4 crtc=#1→NULL (VCPI n→0)
* DP-5 crtc=NULL→#1
* CRTC #1 steals encoder #1 back from DP-4 and gives it to DP-5
* CRTC #1 maintains the same mode as before, just with a different
connector
* mode_changed=n connectors_changed=y
(we _SHOULD_ do VCPI 0→n here, but don't)
Once the above scenario is repeated once, we'll attempt freeing VCPI
from the connector that we didn't allocate due to the connectors
changing, but the mode staying the same. Sigh.
Since nv50_msto_atomic_check() has broken a few times now, let's rethink
things a bit to be more careful: limit both VCPI/PBN allocations to
mode_changed || connectors_changed, since neither VCPI or PBN should
ever need to change outside of routing and mode changes.
Changes since v1:
* Fix accidental reversal of clock and bpp arguments in

Looks like a regression got introduced into nv50_mstc_atomic_check()
that somehow didn't get found until now. If userspace changes
crtc_state->active to false but leaves the CRTC enabled, we end up
calling drm_dp_atomic_find_vcpi_slots() using the PBN calculated in
asyh->dp.pbn. However, if the display is inactive we end up calculating
a PBN of 0, which inadvertently causes us to have an allocation of 0.
>From there, if userspace then disables the CRTC afterwards we end up
accidentally attempting to free the VCPI twice:

So, fix this by doing what we probably should have done from the start: only
call drm_dp_atomic_find_vcpi_slots() when crtc_state->mode_changed is set, so
that VCPI allocations remain for as long as the CRTC is enabled.

Currently nouveau_svm_fault expects nouveau_range_fault to never unlock
mmap_sem, but the latter unlocks it for a random selection of error
codes. Fix this up by always unlocking mmap_sem for non-zero return values
in nouveau_range_fault, and only unlocking it in the caller for successful
returns.

The parameter is always false, so remove it as well as the -EAGAIN

These two functions are marked as a legacy APIs to get rid of, but seem to
suit the current nouveau flow. Move it to the only user in preparation
for fixing a locking bug involving caller and callee. All comments
referring to the old API have been removed as this now is a driver private
helper.

Pull drm fixes from Daniel Vetter:
"Dave is back in shape, but now family got it so I'm doing the pull.
Two things worthy of note:
- nouveau feature pull was way too late, Dave&me decided to not take
that, so Ben spun up a pull with just the fixes.
- after some chatting with the arm display maintainers we decided to
change a bit how that's maintained, for more oversight/review and
cross vendor collab.
More details below:
nouveau:
- bugfixes
- TU116 enabling (minor iteration) :w
amdgpu:
- large pile of fixes for new hw support this release (navi, vega20)
- audio hotplug fix
- bunch of corner cases and small fixes all over for amdgpu/kfd
komeda:
- back out some new properties (from this merge window) that needs
more pondering.
bochs:
- fb pitch setup
core:
- a new panel quirk
- misc fixes"

In nouveau_conn_reset(), if connector->state is true,
__drm_atomic_helper_connector_destroy_state() will be called,
but the memory pointed by asyc isn't freed. Memory leak happens
in the following function __drm_atomic_helper_connector_reset(),
where newly allocated asyc->state will be assigned to connector->state.
So using nouveau_conn_atomic_destroy_state() instead of
__drm_atomic_helper_connector_destroy_state to free the "old" asyc.
Here the is the log showing memory leak.

It turns out that while disabling i2c bus access from software when the
GPU is suspended was a step in the right direction with:
commit 342406e4fbba ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")
We also ended up accidentally breaking the vbios init scripts on some
older Tesla GPUs, as apparently said scripts can actually use the i2c
bus. Since these scripts are executed before initializing any
subdevices, we end up failing to acquire access to the i2c bus which has
left a number of cards with their fan controllers uninitialized. Luckily
this doesn't break hardware - it just means the fan gets stuck at 100%.
This also means that we've always been using our i2c busses before
initializing them during the init scripts for older GPUs, we just didn't
notice it until we started preventing them from being used until init.
It's pretty impressive this never caused us any issues before!
So, fix this by initializing our i2c pad and busses during subdev
pre-init. We skip initializing aux busses during pre-init, as those are
guaranteed to only ever be used by nouveau for DP aux transactions.

Modesetting only, still waiting on ACR/GR firmware from NVIDIA for Turing
graphics/compute bring-up.
Each subsystem was compared with traces, along with various tests to check
that things generally work as they should, and appears compatible enough
with the current TU117 code to enable support.

The fallthrough cases (pre-Fermi) would accidentally allow dual-link pixel
clocks even where they shouldn't be. This leads to a high resolution HDMI
displays, connected via a DVI->HDMI adapter, to fail on the original NV50.

Previously center scaling would get scaling applied to it (when it was
only supposed to center the image), and aspect-corrected scaling did not
always correctly pick whether to reduce width or height for a particular
combination of inputs/outputs.

Higher layers tend to add a lot of modes not actually in the EDID, such
as the standard DMT modes. Changing this would be extremely intrusive to
everyone, so just force the scaler more often. There are no practical
cases we're aware of where a LVDS/eDP panel has multiple resolutions
exposed, and i915 already does it this way.

Everyone who implements connector_helper_funcs->atomic_check reaches
into the connector state to get the atomic state. Instead of continuing
this pattern, change the callback signature to just give atomic state
and let the driver determine what it does and does not need from it.
Eventually all atomic functions should do this, but that's just too much
busy work for me.
Changes in v3:
- Added to the set
Changes in v4:
- None
Changes in v5:
- intel_digital_connector_atomic_check declaration moved to i915_atomic.h

__drm_atomic_helper_plane_reset(), extend this to crtc as well.
This will allow us to set default values in the crtc_state, without
having to do it in each driver separately.
Of all drivers that need conversion, only nouveau is done in this
commit, because it wrote its own __drm_atomic_helper_crtc_reset(),
clashing with the drm core.

Christoph Hellwig says:
====================
Below is a series that cleans up the dev_pagemap interface so that it is
more easily usable, which removes the need to wrap it in hmm and thus
allowing to kill a lot of code
Changes since v3:
- pull in "mm/swap: Fix release_pages() when releasing devmap pages" and
rebase the other patches on top of that
- fold the hmm_devmem_add_resource into the DEVICE_PUBLIC memory removal
patch
- remove _vm_normal_page as it isn't needed without DEVICE_PUBLIC memory
- pick up various ACKs
Changes since v2:
- fix nvdimm kunit build
- add a new memory type for device dax
- fix a few issues in intermediate patches that didn't show up in the end
result
- incorporate feedback from Michal Hocko, including killing of
the DEVICE_PUBLIC memory type entirely
Changes since v1:
- rebase
- also switch p2pdma to the internal refcount
- add type checking for pgmap->type
- rename the migrate method to migrate_to_ram
- cleanup the altmap_valid flag
- various tidbits from the reviews
====================
Conflicts resolved by:
- Keeping Ira's version of the code in swap.c
- Using the delete for the section in hmm.rst
- Using the delete for the devmap code in hmm.c and .h
* branch 'hmm-devmem-cleanup.4': (24 commits)

All the mm/hmm.c code is better keyed off HMM_MIRROR. Also let nouveau
depend on it instead of the mix of a dummy dependency symbol plus the
actually selected one. Drop various odd dependencies, as the code is

" This is a bit more than I'd like to be pushing at this point in a
cycle, but it's a fairly important issue. There's been numerous
reports of more recent GP10[2467] boards failing to load, and I've
worked with NVIDIA FW engineers and tracked this down to the FW we've
been using not properly supporting the boards in question.
I've pushed an update to linux-firmware with the new FW version, which
unfortunately contains API changes vs the older firmware.
This series teaches the ACR subsystem inside nouveau enough to be able
to deal with supporting multiple incompatible FW revisions, and adds
support to the relevant chipsets for loading the newer FW revision, if
it's available."

some boards
Some newer boards with these chipsets aren't compatible with the prior
version of the SEC2 FW, and fail to load as a result.
This newer FW is actually the one we already use on >=GP108.
Unfortunately, there are interface differences in GP108's FW, making it
impossible to simply move files around in linux-firmware to solve this.
We need to be able to keep compatibility with all linux-firmware/kernel
combinations, which means supporting both firmwares.

Ralph observes that hmm_range_register() can only be called by a driver
while a mirror is registered. Make this clear in the API by passing in the
mirror structure as a parameter.
This also simplifies understanding the lifetime model for struct hmm, as
the hmm pointer must be valid as part of a registered mirror so all we
need in hmm_register_range() is a simple kref_get.

nv50_head_atomic_duplicate_state() makes a copy of nv50_head_atom
struct. This patch adds copying of struct member named "or", which
previously was left uninitialized in the duplicated structure.
Due to this bug, incorrect nhsync and nvsync values were sometimes used.
In my particular case, that lead to a mismatch between the output
resolution of the graphics device (GeForce GT 630 OEM) and the reported
input signal resolution on the display. xrandr reported 1680x1050, but
the display reported 1280x1024. As a result of this mismatch, the output
on the display looked like it was cropped (only part of the output was
actually visible on the display).
git bisect pointed to commit 2ca7fb5c1cc6 ("drm/nouveau/kms/nv50: handle
SetControlOutputResource from head"), which added the member "or" to
nv50_head_atom structure, but forgot to copy it in
nv50_head_atomic_duplicate_state().
