1e339ab2ac drm/nouveau/kms/tu102-: disable input lut when input is already FP16
On Turing, an input LUT is required to transform inputs in fixed-point
formats to FP16 for the internal display pipe.  We provide an identity
mapping whenever a window is enabled for this reason.

HW has error checks to ensure when the input is already FP16, that the
input LUT is also disabled.

7b97492555 drm/nouveau/mmu: use struct_size() helper
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace the following form:

sizeof(*kind) + sizeof(*kind->data) * mmu->kind_nr;

with:

struct_size(kind, data, mmu->kind_nr)

This code was detected with the help of Coccinelle.

c358ebf596 drm/nouveau: Don't retry infinitely when receiving no data on i2c over AUX
While I had thought I had fixed this issue in:

commit 342406e4fb ("drm/nouveau/i2c: Disable i2c bus access after
->fini()")

It turns out that while I did fix the error messages I was seeing on my
P50 when trying to access i2c busses with the GPU in runtime suspend, I
accidentally had missed one important detail that was mentioned on the
bug report this commit was supposed to fix: that the CPU would only lock
up when trying to access i2c busses _on connected devices_ _while the
GPU is not in runtime suspend_. Whoops. That definitely explains why I
was not able to get my machine to hang with i2c bus interactions until
now, as plugging my P50 into it's dock with an HDMI monitor connected
allowed me to finally reproduce this locally.

Now that I have managed to reproduce this issue properly, it looks like
the problem is much simpler then it looks. It turns out that some
connected devices, such as MST laptop docks, will actually ACK i2c reads
even if no data was actually read:

[  275.063043] nouveau 0000:01:00.0: i2c: aux 000a: 1: 0000004c 1
[  275.063447] nouveau 0000:01:00.0: i2c: aux 000a: 00 01101000 10040000
[  275.063759] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000001
[  275.064024] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
[  275.064285] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000
[  275.064594] nouveau 0000:01:00.0: i2c: aux 000a: rd 00000000

Because we don't handle the situation of i2c ack without any data, we
end up entering an infinite loop in nvkm_i2c_aux_i2c_xfer() since the
value of cnt always remains at 0. This finally properly explains how
this could result in a CPU hang like the ones observed in the
aforementioned commit.

So, fix this by retrying transactions if no data is written or received,
and give up and fail the transaction if we continue to not write or
receive any data after 32 retries.

Jason Gunthorpe says:

====================
This is a collection of general cleanups for ODP to clarify some of the
flows around umem creation and use of the interval tree.
====================

The branch is based on v5.3-rc5 due to dependencies, and is being taken
into hmm.git due to dependencies in the next patches.

* odp_fixes:
  RDMA/mlx5: Use odp instead of mr->umem in pagefault_mr
  RDMA/mlx5: Use ib_umem_start instead of umem.address
  RDMA/core: Make invalidate_range a device operation
  RDMA/odp: Use kvcalloc for the dma_list and page_list
  RDMA/odp: Check for overflow when computing the umem_odp end
  RDMA/odp: Provide ib_umem_odp_release() to undo the allocs
  RDMA/odp: Split creating a umem_odp from ib_umem_get
  RDMA/odp: Make the three ways to create a umem_odp clear
  RMDA/odp: Consolidate umem_odp initialization
  RDMA/odp: Make it clearer when a umem is an implicit ODP umem

019cbd4a4f drm/nouveau: Initialize GEM object before TTM object
TTM assumes that drivers initialize the embedded GEM object before
calling the ttm_bo_init() function. This is not currently the case
in the Nouveau driver. Fix this by splitting up nouveau_bo_new()
into nouveau_bo_alloc() and nouveau_bo_init() so that the GEM can
be initialized before TTM BO initialization when necessary.

There isn't any good reason to pass callbacks to migrate_vma.  Instead
we can just export the three steps done by this function to drivers and
let them sequence the operation without callbacks.  This removes a lot

improve code flow and error handling further on.

c7d8b7824f hmm: use mmu_notifier_get/put for 'struct hmm'
This is a significant simplification, it eliminates all the remaining
'hmm' stuff in mm_struct, eliminates krefing along the critical notifier
paths, and takes away all the ugly locking and abuse of page_table_lock.

mmu_notifier_get() provides the single struct hmm per struct mm which
eliminates mm->hmm.

It also directly guarantees that no mmu_notifier op callback is callable
while concurrent free is possible, this eliminates all the krefs inside
the mmu_notifier callbacks.

The remaining krefs in the range code were overly cautious, drivers are
already not permitted to free the mirror while a range exists.

db1231ddc0 drm/nouveau: Only recalculate PBN/VCPI on mode/connector changes
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
  drm_dp_calc_pbn_mode() - William Lewis

that uses the huge page size instead of having the caller calculate that

412e85b605 drm/nouveau: Only release VCPI slots on mode changes
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.

aa77e7f6d5 drm/nouveau: Fill out gem_object->resv
That way we can ditch our gem_prime_res_obj implementation. Since ttm
absolutely needs the right reservation object all the boilerplate is
already there and we just have to wire it up correctly.

Note that gem/prime doesn't care when we do this, as long as we do it
before the bo is registered and someone can call the handle2fd ioctl
on it.

Aside: ttm_buffer_object.ttm_resv could probably be ditched in favour
of always passing a non-NULL resv to ttm_bo_init(). At least for gem
drivers that would avoid having two of these, on in ttm_buffer_object
and the other in drm_gem_object, one just there for confusion.

1b88b99bdf nouveau: return -EBUSY when hmm_range_wait_until_valid fails
-EAGAIN has a magic meaning for non-blocking faults, so don't overload it.
Given that the caller doesn't check for specific error codes this change
is purely cosmetic.

02712bc325 mm/hmm: move hmm_vma_range_done and hmm_vma_fault to nouveau
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.

09b90e2fe3 drm/nouveau: fix memory leak in nouveau_conn_reset()
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.

7cb95eeea6 drm/nouveau/i2c: Enable i2c pads & busses during preinit
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 342406e4fb ("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.

533f475240 drm/nouveau/disp/nv50-: fix center/aspect-corrected scaling
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.

f8d6211ac7 drm/nouveau/disp/nv50-: force scaler for any non-default LVDS/eDP modes
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.

cc5dfd59e3 Merge branch 'hmm-devmem-cleanup.4' into rdma.git hmm
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

6f3b62781b drm: Convert connector_helper_funcs->atomic_check to accept drm_atomic_state
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

e36acfe6c8 mm/hmm: Use hmm_mirror not mm as an argument for hmm_range_register
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.

" 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."

ab4bec16d4 drm/nouveau/secboot/gp10[2467]: support newer FW to fix SEC2 failures on 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.

c4a52d6696 drm/nouveau: fix duplication of nv50_head_atom struct
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 2ca7fb5c1c ("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().
