drm_helper_probe_single_connector_modes, v4.
mode_valid() called from drm_helper_probe_single_connector_modes()
may need to look at connector->state because what a valid mode is may
depend on connector properties being set. For example some HDMI modes
might be rejected when a connector property forces the connector
into DVI mode.
Some implementations of detect() already lock all state,
so we have to pass an acquire_ctx to them to prevent a deadlock.
This means changing the function signature of detect() slightly,
and passing the acquire_ctx for locking multiple crtc's.
For the callbacks, it will always be non-zero. To allow callers
not to worry about this, drm_helper_probe_detect_ctx is added
which might handle -EDEADLK for you.
Changes since v1:
- Always set ctx parameter.
Changes since v2:
- Always take connection_mutex when probing.
Changes since v3:
- Remove the ctx from intel_dp_long_pulse, and add
WARN_ON(!connection_mutex) (danvet)
- Update docs to clarify the locking situation. (danvet)

When we use virtio-vga with a big-endian guest,
the mouse pointer disappears.
To fix that, on big-endian use DRM_FORMAT_BGRA8888
instead of DRM_FORMAT_ARGB8888.

The goal is to push all the kms locking down into these separate
_atomic and _legacy functions, so that we can correctly pass the
acquire ctx into all atomic drivers. Instead of playing games with
hidden ctx in mode_config.acquire_ctx. All the fbdev state will be
protected by a new fbdev private lock that Thierry is working on.
This here is just prep by creating a clean split between atomic and
legacy paths, which also simplifies the control flow a bit.

I got confused every time I audited what that lock_all is doing in
there until realizing it's for legacy kms only. Make that a notch more
obvious by having 2 entirely different paths.
While at it also move the atomic version of this into
drm_framebuffer.c, there's no reason it needs to be in drm_atomic.c.
That way it becomes a simple static function.

Atomic helpers really want this instead of the hacked-up legacy
backoff trick, which unfortunately prevents drivers from using their
own private drm_modeset_locks.
Aside: There's a few atomic drivers (nv50, vc4, soon vmwgfx) which
don't yet use the new atomic color mgmt/gamma table stuff. Would be
nice if they could switch over and just hook up
drm_atomic_helper_legacy_gamma_set() instead.

It just doesn't work. It probably stopped working way, way before that
(e.g. i915 grabbed random mutexes all over in modeset code at least
since gen6), but with atomic and all the ww_mutex stuff it's indeed
hopeless.
Remove ->mode_set_base_atomic from the 2 atomic drivers (i915 and
nouveau) that still had one (both had dummy implementations already
anyway), and shunt atomic drivers in the helpers debug_enter/leave
functions.
I'll leave the code in for radeon and amdgpu, but I think as soon as
amdgpu is atomic we should think about just ripping it out. Only
having it around for radeon and pre-nv50 is rather pointless. This
would also allow us to nuke all that code from fbdev.
Funny part is that _all_ kms drivers set this hook, despite that no
one else provides the required ->mode_set_base_atomic implementation.
The reason I'm jumping on this is that I want to wire up a full
acquire ctx for the benefit of atomic drivers, everywhere. And the
debug_enter/leave implementations call ->gamma_set. And there's just
no way ever we can create an acquire_ctx in the nmi context of kgdb.

We do set DRIVER_ATOMIC now.
Note that the comment is outdated, the property paths switched over to
checking drm_drv_uses_atomic_modeset() a while ago. Which means this
can't even break if we revert DRIVER_ATOMIC again.

We don't call into drivers at all here, this is enough. Also, we can
reduce the critical section a bit to simplify the code.
crtc->gamma_size is set up once at driver load and then invariant, so
also doesn't need any protection.

Properties, i.e. the struct drm_property specifying the type and value
range of a property, not the instantiation on a given object, are
invariant over the lifetime of a driver.
Hence no locking at all is needed, we can just remove it.
While at it give the function some love and simplify it, to get it
under the 80 char limit:
- Straighten the loops to reduce the nesting.
- use u64_to_user_ptr casting helper
- use put_user for fixed u64 copies.
Note there's a small behavioural change in that we now copy parts of
the values to userspace if the arrays are a bit too small. Since
userspace will immediately retry anyway, this doesn't matter.

If we push the locks down we don't have to take them all at the same
time.
Aside: Making dump_info fully safe should be fairly simple, if we
protect the ->state pointers with rcu. Simply putting a
synchronize_rcu() into the drm_atomic_state free function should be
all that's roughly needed. Well except we shouldn't block in there, so
better to put that into a work_struct. But I've not set out to fix
that little issue.

With the atomic API, it is possible that a single commit affects
multiple crtcs. If the user requests an event with that commit, one
event will be sent for each CRTC, but it is not possible to distinguish
which crtc an event is for in user space. To solve this, the reserved
field in struct drm_vblank_event is repurposed to include the crtc_id
which the event is for.
The DRM_CAP_CRTC_IN_VBLANK_EVENT is added to allow userspace to query if
the crtc field will be set properly.

Also unify/merge with the existing stuff.
I was a bit torn where to put this, but in the end I decided to put
all the ioctl/sysfs/debugfs stuff into drm-uapi.rst. That means we
have a bit a split with the other uapi related stuff used internally,
like drm_file.[hc], but I think overall this makes more sense.
If it's too confusing we can always add more cross-links to make it
more discoverable. But the auto-sprinkling of links kernel-doc already
does seems sufficient.
Also for prettier docs and more cross-links, switch the internal
defines over to an enum, as usual.
v2: Update kerneldoc fro drm_compat_ioctl too (caught by 0day), plus a
bit more drive-by polish.
v3: Fix typo, spotted by xerpi on irc (Sergi).

The HDMI TX controller support HPD and RXSENSE signaling from the PHY
via it's STAT0 PHY interface, but some vendor PHYs can manage these
signals independently from the controller, thus these STAT0 handling
should be moved to PHY specific operations and become optional.
The existing STAT0 HPD and RXSENSE handling code is refactored into
a supplementaty set of default PHY operations that are used automatically
when the platform glue doesn't provide its own operations.

The code responsible for splitting periods into chunks that
can be handled by the DMA controller missed to update total_len,
the number of bytes processed in the current period, when there
are more chunks to follow.
Therefore total_len was stuck at 0 and the code didn't work at all.
This resulted in a wrong control block layout and audio issues because
the cyclic DMA callback wasn't executing on period boundaries.
Fix this by adding the missing total_len update.

Pull scheduler fixes from Thomas Gleixner:
"This update provides:
- make the scheduler clock switch to unstable mode smooth so the
timestamps stay at microseconds granularity instead of switching to
tick granularity.
- unbreak perf test tsc by taking the new offset into account which
was added in order to proveide better sched clock continuity
- switching sched clock to unstable mode runs all clock related
computations which affect the sched clock output itself from a work
queue. In case of preemption sched clock uses half updated data and
provides wrong timestamps. Keep the math in the protected context
and delegate only the static key switch to workqueue context.
- remove a duplicate header include"

The Intel Compute Stick STCK1A8LFC and Weibu F3C platforms both
log 2 error messages during boot:
efi: requested map not found.
esrt: ESRT header is not in the memory map.
Searching the web, this seems to affect many other platforms too.
Since these messages are logged as errors, they appear on-screen during
the boot process even when using the "quiet" boot parameter used by
distros.
Demote the ESRT error to a warning so that it does not appear on-screen,
and delete the error logging from efi_mem_desc_lookup; both callsites
of that function log more specific messages upon failure.
Out of curiosity I looked closer at the Weibu F3C. There is no entry in
the UEFI-provided memory map which corresponds to the ESRT pointer, but
hacking the code to map it anyway, the ESRT does appear to be valid with
2 entries.

Commit 4cfffcfa5106 ("irqchip/mips-gic: Fix local interrupts") added
mapping of several local interrupts during initialisation of the gic
driver. This associates virq numbers with these interrupts.
Unfortunately, as not all of the interrupts are mapped in hardware
order, when drivers subsequently request these interrupts they conflict
with the mappings that have already been set up. For example, this
manifests itself in the gic clocksource driver, which fails to probe
with the message:
clocksource: GIC: mask: 0xffffffffffffffff max_cycles: 0x7350c9738,
max_idle_ns: 440795203769 ns
GIC timer IRQ 25 setup failed: -22
This is because virq 25 (the correct IRQ number specified via device
tree) was allocated to the PERFCTR interrupt (and 24 to the timer, 26 to
the FDC). To fix this, map all of these local interrupts in the hardware
order so as to associate their virq numbers with the correct hw
interrupts.

This driver uses the MSI domain but has no strict dependency on PCI_MSI, so we
may run into a build failure when CONFIG_GENERIC_MSI_IRQ_DOMAIN is disabled:

Selecting the option from this driver seems to solve this nicely, though I could
not find any other instance of this in irqchip drivers.

There are same conditions for checking whether supporting clkscaling or
not. When ufshcd is supporting clkscaling, active_reqs should be
decreased by one.
