This fixes maybe_unused warnings/errors.
According to a comment during device tree removal, only ACPI is supported,
thus let's actually require it.

Commit 16ce101db85d ("mm/memory.c: fix race when faulting a device private
page") changed the migrate_to_ram() callback to take a reference on the
device page to ensure it can't be freed while handling the fault.
Unfortunately the corresponding update to Nouveau to accommodate this
change was inadvertently dropped from that patch causing GPU to CPU
migration to fail so add it here.

Since a7c01fa93aeb ("signal: break out of wait loops on kthread_stop()")
kthread_stop() started asserting a pending signal which wreaks havoc with
a few of our selftests. Mainly because they are not fully expecting to
handle signals, but also cutting the intended test runtimes short due
signal_pending() now returning true (via __igt_timeout), which therefore
breaks both the patterns of:
kthread_run()
..sleep for igt_timeout_ms to allow test to exercise stuff..
kthread_stop()
And check for errors recorded in the thread.
And also:
Main thread | Test thread
---------------+------------------------------
kthread_run() |
kthread_stop() | do stuff until __igt_timeout
| -- exits early due signal --
Where this kthread_stop() was assume would have a "join" semantics, which
it would have had if not the new signal assertion issue.
To recap, threads are now likely to catch a previously impossible
ERESTARTSYS or EINTR, marking the test as failed, or have a pointlessly
short run time.
To work around this start using kthread_work(er) API which provides
an explicit way of waiting for threads to exit. And for cases where
parent controls the test duration we add explicit signaling which threads
will now use instead of relying on kthread_should_stop().

We use all kinds of weird names for our base address registers.
Take the names from the spec and stick to them to avoid confusing
everyone.
The only exceptions are IOBAR and LMEMBAR since naming them
IOBAR_BAR and LMEMBAR_BAR looks too funny, and yet I think
that adding the _BAR to GTTMMADR & co. (which don't have one
in the spec name) does make it more clear what they are.
And IOBAR vs. GTTMMADR_BAR also looks a bit too inconsistent
for my taste.

Commit 8795e182b02d ("PCI/portdrv: Don't disable AER reporting in get_port_device_capability()")
uncovered a bug in amdgpu that required a reordering of the driver
init sequence to avoid accessing a special register on the GPU
before it was properly set up leading to an PCI AER error. This
reordering uncovered a different hw programming ordering dependency
in some APUs where the SDMA doorbells need to be programmed before
the GFX doorbells. To fix this, move the SDMA doorbell programming
back into the soc15 common code, but use the actual doorbell range
values directly rather than the values stored in the ring structure
since those will not be initialized at this point.
This is a partial revert, but with the doorbell assignment
fixed so the proper doorbell index is set before it's used.

Commit c347a787e34cb (drbd: set ->bi_bdev in drbd_req_new) moved a
bio_set_dev call (which has since been removed) to "earlier", from
drbd_request_prepare to drbd_req_new.
The problem is that this accesses device->ldev->backing_bdev, which is
not NULL-checked at this point. When we don't have an ldev (i.e. when
the DRBD device is diskless), this leads to a null pointer deref.
So, only allocate the private_bio if we actually have a disk. This is
also a small optimization, since we don't clone the bio to only to
immediately free it again in the diskless case.

multiple conditions, calling the function that is tested multiple times
with different arguments.
This usually means that it can be easily converted into multiple test
cases.

drm_check_plane_state and drm_check_invalid_plane_state.

__le32 and __le64 types aren't portable and are not available on
FreeBSD (which uses the same uAPI).
Instead of attempting to always output little endian, just use native
endianness in the dumps. Tools can detect the endianness in use by
looking at the 'magic' field, but equally we don't expect big-endian to
be used with Mali (there are no known implementations out there).

Commit 35a3b82f1bdd ("drm/connector: Introduce drmm_connector_init")
introduced the function drmm_connector_init() with a parameter for an
optional ddc pointer to the i2c controller used to access the DDC bus.
However, the underlying call to __drm_connector_init() was always
setting it to NULL instead of passing the ddc argument around.
This resulted in unexpected null pointer dereference on platforms
expecting to get a DDC controller.

The xrgb2101010 format conversion test (unlike for other formats) does
an endianness conversion on the results. However, it always converts
TEST_BUF_SIZE 32-bit integers, which results in reading from (and
writing to) more memory than in present in the result buffer. Instead,
use the buffer size, divided by sizeof(u32).
The issue could be reproduced with KASAN:

--kconfig_add CONFIG_KASAN=y --kconfig_add CONFIG_KASAN_VMALLOC=y \

If the cable is disconnected the PHY seems to toggle between MDI and

roughly 10 interrupts per second.
As the crossover status isn't checked by the driver, the interrupt can
be disabled to reduce the interrupt load.

The fb_base in struct drm_mode_config has been unused for a long time.
Some drivers set it and some don't leading to a very confusing state
where the variable can't be relied upon, because there's no indication
as to which driver sets it and which doesn't.
The only usage of fb_base is internal to two drivers so instead of trying
to force it into all the drivers to get it into a coherent state
completely remove it.

allocated in dev_set_name() is leaked. Fix this by calling

When we compile-in the CCI along with the imx412 driver and run on the RB5
we see that i2c_add_adapter() causes the probe of the imx412 driver to
happen.
This probe tries to perform an i2c xfer() and the xfer() in i2c-qcom-cci.c
fails on pm_runtime_get() because the i2c-qcom-cci.c::probe() function has
not completed to pm_runtime_enable(dev).
Fix this sequence by ensuring pm_runtime_xxx() calls happen prior to adding
the i2c adapter.

Assigning the device's dma_range_map from the iterator variable after
the loop means it always points to the empty terminator at the end of
the map, which is not what we want. Similarly, freeing the iterator on
error when it points to somwhere in the middle of the allocated array
won't work either. Fix this.

Add partial live video support, with a single video input that bypasses
blending. Skip registration of the DRM device in that case, but register
the DRM bridge instead. The DRM device will be created by the driver for
the display controller in the PL.
Full live video mode with concurrent usage of the video and gfx inputs,
and blending in the DPSUB video pipeline, is currently unsupported.

To complete the decoupling of the DRM device from the zynqmp_dpsub,
group all DRM-related structures in a zynqmp_dpsub_drm structure and
allocate it separately from the zynqmp_dpsub. The DRM managed allocation
of the drm_device now doesn't cover the zynqmp_dpsub anymore, so we need
to register a cleanup action to release the zynqmp_dpsub when the
drm_device is released.
The will allow usage of the DisplayPort encoder as a standalone bridge,
without registering a DRM device in this driver.

The zynqmp_disp and zynqmp_dp structures are allocated with
drmm_kzalloc(). While this simplifies management of memory, it requires
a DRM device, which will not be available at probe time when the DP
bridge will be used standalone, with a DRM device in the PL. To prepare
for this, switch to manual allocation for zynqmp_disp and zynqmp_dp. The
cleanup still uses the DRM managed infrastructure, but one level up, at
the top level. This will be addressed separately.
