Fix the calculation of the DSC line buffer depth. This is limited both
by the source's and sink's maximum line buffer depth, but the former one
was not taken into account. On all Intel platform's the source's maximum
buffer depth is 13, so the overall limit is simply the minimum of the
source/sink's limit, regardless of the DSC version.
This leaves the DSI DSC line buffer depth calculation as-is, trusting
VBT.
On DSC version 1.2 for sinks reporting a maximum line buffer depth of 16
the line buffer depth was incorrectly programmed as 0, leading to a
corruption in color gradients / lines on the decompressed screen image.

ARL-H uses the same media and display IP as MTL, and a version 12.74
graphics IP (referred to as Xe_LPG+). From a driver point of view, we
should be able to just treat the whole platform as MTL and rely on
GRAPHICS_VERx100 checks to handle any spots where ARL's Xe_LPG+ needs
different handling from MTL's Xe_LPG (i.e., workarounds).

suggested to change the name of the function `drm_panic_gem_get_scanout_buffer`
to `drm_fb_dma_get_scanout_buffer` and this request was applied on version 12,
which is the version that landed [2]. Although the name of the function
changed on the C file, it didn't changed on the header file, leading to a
compilation error as such:
drivers/gpu/drm/imx/ipuv3/ipuv3-plane.c:780:24: error: use of undeclared
identifier 'drm_fb_dma_get_scanout_buffer'; did you mean 'drm_panic_gem_get_scanout_buffer'?

1 error generated.
Fix the compilation error by changing `drm_panic_gem_get_scanout_buffer` to
`drm_fb_dma_get_scanout_buffer` on the header file.

(Thomas Zimmermann)
v9:
* go back to get_scanout_buffer()
* move get_scanout_buffer() to plane helper functions
v12:
* Rename drm_panic_gem_get_scanout_buffer to drm_fb_dma_get_scanout_buffer
(Thomas Zimmermann)
* Remove the #ifdef CONFIG_DRM_PANIC, and build it unconditionnaly, as
it's a small function. (Thomas Zimmermann)

Rough sketch for the locking of drm panic printing code. The upshot of
this approach is that we can pretty much entirely rely on the atomic
commit flow, with the pair of raw_spin_lock/unlock providing any
barriers we need, without having to create really big critical
sections in code.
This also avoids the need that drivers must explicitly update the
panic handler state, which they might forget to do, or not do
consistently, and then we blow up in the worst possible times.
It is somewhat racy against a concurrent atomic update, and we might
write into a buffer which the hardware will never display. But there's
fundamentally no way to avoid that - if we do the panic state update
explicitly after writing to the hardware, we might instead write to an
old buffer that the user will barely ever see.
Note that an rcu protected deference of plane->state would give us the
the same guarantees, but it has the downside that we then need to
protect the plane state freeing functions with call_rcu too. Which
would very widely impact a lot of code and therefore doesn't seem
worth the complexity compared to a raw spinlock with very tiny
critical sections. Plus rcu cannot be used to protect access to
peek/poke registers anyway, so we'd still need it for those cases.
Peek/poke registers for vram access (or a gart pte reserved just for
panic code) are also the reason I've gone with a per-device and not
per-plane spinlock, since usually these things are global for the
entire display. Going with per-plane locks would mean drivers for such
hardware would need additional locks, which we don't want, since it
deviates from the per-console takeoverlocks design.
Longer term it might be useful if the panic notifiers grow a bit more
structure than just the absolute bare
EXPORT_SYMBOL(panic_notifier_list) - somewhat aside, why is that not
EXPORT_SYMBOL_GPL ... If panic notifiers would be more like console
drivers with proper register/unregister interfaces we could perhaps
reuse the very fancy console lock with all it's check and takeover
semantics that John Ogness is developing to fix the console_lock mess.
But for the initial cut of a drm panic printing support I don't think
we need that, because the critical sections are extremely small and
only happen once per display refresh. So generally just 60 tiny locked
sections per second, which is nothing compared to a serial console
running a 115kbaud doing really slow mmio writes for each byte. So for
now the raw spintrylock in drm panic notifier callback should be good
enough.
Another benefit of making panic notifiers more like full blown
consoles (that are used in panics only) would be that we get the two
stage design, where first all the safe outputs are used. And then the
dangerous takeover tricks are deployed (where for display drivers we
also might try to intercept any in-flight display buffer flips, which
if we race and misprogram fifos and watermarks can hang the memory
controller on some hw).
For context the actual implementation on the drm side is by Jocelyn
and this patch is meant to be combined with the overall approach in
v7 (v8 is a bit less flexible, which I think is the wrong direction):
https://lore.kernel.org/dri-devel/20240104160301.185915-1-jfalempe@redhat.com/
Note that the locking is very much not correct there, hence this
separate rfc.
Starting from v10, I (Jocelyn) have included this patch in the drm_panic
series, and done the corresponding changes.
v2:
- fix authorship, this was all my typing
- some typo oopsies
- link to the drm panic work by Jocelyn for context
v10:
- Use spinlock_irqsave/restore (John Ogness)
v11:
- Use macro instead of inline functions for drm_panic_lock/unlock (John Ogness)

Add a new immutable plane property by which a plane can advertise
a handful of recommended plane sizes. This would be mostly exposed
by cursor planes as a slightly more capable replacement for
the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare
a one size fits all limit for the whole device.
Currently eg. amdgpu/i915/nouveau just advertize the max cursor
size via the cursor size caps. But always using the max sized
cursor can waste a surprising amount of power, so a better
strategy is desirable.
Most other drivers don't specify any cursor size at all, in
which case the ioctl code just claims that 64x64 is a great
choice. Whether that is actually true is debatable.
A poll of various compositor developers informs us that
blindly probing with setcursor/atomic ioctl to determine
suitable cursor sizes is not acceptable, thus the
introduction of the new property to supplant the cursor
size caps. The compositor will now be free to select a
more optimal cursor size from the short list of options.
Note that the reported sizes (either via the property or the
caps) make no claims about things such as plane scaling. So
these things should only really be consulted for simple
"cursor like" use cases.
Userspace consumer in the form of mutter seems ready:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3165
v2: Try to add some docs
v3: Specify that value 0 is reserved for future use (basic idea from Jonas)
Drop the note about typical hardware (Pekka)
v4: Update the docs to indicate the list is "in order of preference"
Add a a link to the mutter MR
v5: Limit to cursors only for now (Simon)

Implement polling for VGA and SIL164 connectors. Set the flag
DRM_CONNECTOR_POLL_DISCONNECT for each to detect the removal of the
monitor cable. Implement struct drm_connector_helper_funcs.detect_ctx
for each type of connector by testing for EDID data.
The helper drm_connector_helper_detect_ctx() implements .detect_ctx()
on top of the connector's DDC channel. The function can be used by
other drivers as companion to drm_connector_helper_get_modes().
v6:
- change helper name to drm_connector_helper_detec_from_ddc()
(Maxime, Sui)
v5:
- share implementation in drm_connector_helper_detect_ctx() (Maxime)
- test for DDC presence with drm_probe_ddc() (Maxime, Jani)

As well noted by Pekka[1], the rounding of drm_fixp2int_round is wrong.
To round a number, you need to add 0.5 to the number and floor that,
drm_fixp2int_round() is adding 0.0000076. Make it add 0.5.

The .get_modes() callback is supposed to return the number of modes,
never a negative error code. If a negative value is returned, it'll just
be interpreted as a negative count, and added to previous calculations.
Document the rules, but handle the negative values gracefully with an
error message.

Combining allocation and registration is an anti-pattern that should be
avoided. Add two new functions for allocating and registering an dp-hpd
bridge with a proper 'devm' prefix so that it is clear that these are
device managed interfaces.
devm_drm_dp_hpd_bridge_alloc()
devm_drm_dp_hpd_bridge_add()
The new interface will be used to fix a use-after-free bug in the
Qualcomm PMIC GLINK driver and may prevent similar issues from being
introduced elsewhere.
The existing drm_dp_hpd_bridge_register() is reimplemented using the
above and left in place for now.

While most display helpers Kconfig symbols have the DRM_DISPLAY prefix,
the DisplayPort CEC tunnelling implementation uses CONFIG_DRM_DISPLAY_DP_AUX_CEC.
Since the number of users is limited, we can easily rename it to make it
consistent.

In response to my patch removing the "wait for HPD" logic at the
beginning of the MSM DP transfer() callback [1], we had some debate
about what the "This is an optional function" meant in the
documentation of the wait_hpd_asserted() callback. Let's clarify.
As talked about in the MSM DP patch [1], before wait_hpd_asserted()
was introduced there was no great way for panel drivers to wait for
HPD in the case that the "built-in" HPD signal was used. Panel drivers
could only wait for HPD if a GPIO was used. At the time, we ended up
just saying that if we were using the "built-in" HPD signal that DP
AUX controllers needed to wait for HPD themselves at the beginning of
their transfer() callback. The fact that the wait for HPD at the
beginning of transfer() was awkward/problematic was the whole reason
wait_hpd_asserted() was added.
Let's make it obvious that if a DP AUX controller implements
wait_hpd_asserted() that they don't need a loop waiting for HPD at the
start of their transfer() function. We'll still allow DP controllers
to work the old way but mark it as deprecated.

Create a type drm_edid_ident as the identity of an EDID. Currently it
contains panel id and monitor name.
Create a function that can match a given EDID and an identity:
1. Reject if the panel id doesn't match.
2. If name is not null in identity, try to match it in the detailed timing
blocks. Note that some panel vendors put the monitor name after
EDID_DETAIL_MONITOR_STRING.

It's found that some panels have variants that they share the same panel id
although their EDID and names are different. Besides panel id, now we need
more information from the EDID base block to distinguish these panel
variants.
Add drm_edid_read_base_block() to return the EDID base block, which is
wrapped in struct drm_edid.
Caller can further use it to get panel id or check if the block contains
certain strings, such as panel name.
Merge drm_edid_get_panel_id() and edid_extract_panel_id() into one
function.

Temporarily lock the fbdev buffer object during updates to prevent
memory managers from evicting/moving the buffer. Moving a buffer
object while update its content results in undefined behaviour.
Fbdev-generic updates its buffer object from a shadow buffer. Gem-shmem
and gem-dma helpers do not move buffer objects, so they are safe to be
used with fbdev-generic. Gem-vram and qxl are based on TTM, but pin
buffer objects are part of the vmap operation. So both are also safe
to be used with fbdev-generic.
Amdgpu and nouveau do not pin or lock the buffer object during an
update. Their TTM-based memory management could move the buffer object
while the update is ongoing.
The new vmap_local and vunmap_local helpers hold the buffer object's
reservation lock during the buffer update. This prevents moving the
buffer object on all memory managers.

Acquire the buffer object's reservation lock in drm_gem_pin() and
remove locking the drivers' GEM callbacks where necessary. Same for
unpin().
DRM drivers and memory managers modified by this patch will now have
correct dma-buf locking semantics: the caller is responsible for
holding the reservation lock when calling the pin or unpin callback.
DRM drivers and memory managers that are not modified will now be
protected against concurent invocation of their pin and unpin callbacks.
PRIME does not implement struct dma_buf_ops.pin, which requires
the caller to hold the reservation lock. It does implement struct
dma_buf_ops.attach, which requires to callee to acquire the
reservation lock. The PRIME code uses drm_gem_pin(), so locks
are now taken as specified. Same for unpin and detach.
The patch harmonizes GEM pin and unpin to have non-interruptible
reservation locking across all drivers, as is already the case for
vmap and vunmap. This affects gem-shmem, gem-vram, loongson, qxl and
radeon.
