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.

While the commit d807ad80d8 ("drm/bridge: add ->edid_read hook and
drm_bridge_edid_read()") and the commit 27b8f91c08 ("drm/bridge:
remove ->get_edid callback") replaced ->get_edid() callback with the
->edid_read(), they failed to update documentation. Fix the drm_bridge
docs to point to edid_read().

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.

when it ever landed in a busy placement since those were considered
compatible.
Rework the whole handling and finally unify the idle and busy handling.
ttm_bo_validate() is now responsible to try idle placement first and then
use the busy placement if that didn't worked.
Drawback is that we now always try the idle placement first for each
validation which might cause some additional CPU overhead on overcommit.

If an eDP panel is not powered on then any attempts to talk to it over
the DP AUX channel will timeout. Unfortunately these attempts may be
quite slow. Userspace can initiate these attempts either via a
/dev/drm_dp_auxN device or via the created i2c device.
Making the DP AUX drivers timeout faster is a difficult proposition.
In theory we could just poll the panel's HPD line in the AUX transfer
function and immediately return an error there. However, this is
easier said than done. For one thing, there's no hard requirement to
hook the HPD line up for eDP panels and it's OK to just delay a fixed
amount. For another thing, the HPD line may not be fast to probe. On
parade-ps8640 we need to wait for the bridge chip's firmware to boot
before we can get the HPD line and this is a slow process.
The fact that the transfers are taking so long to timeout is causing
real problems. The open source fwupd daemon sometimes scans DP busses
looking for devices whose firmware need updating. If it happens to
scan while a panel is turned off this scan can take a long time. The
fwupd daemon could try to be smarter and only scan when eDP panels are
turned on, but we can also improve the behavior in the kernel.
Let's let eDP panels drivers specify that a panel is turned off and
then modify the common AUX transfer code not to attempt a transfer in
this case.

Handle DP tunnel IRQs a sink (or rather a BW management component like

Add support for Display Port tunneling. For now this includes the
support for Bandwidth Allocation Mode (BWA), leaving adding Panel Replay
support for later.
BWA allows using displays that share the same (Thunderbolt) link with
their maximum resolution. Atm, this may not be possible due to the
coarse granularity of partitioning the link BW among the displays on the
link: the BW allocation policy is in a SW/FW/HW component on the link
(on Thunderbolt it's the SW or FW Connection Manager), independent of
the driver. This policy will set the DPRX maximum rate and lane count
DPCD registers the GFX driver will see (0x00000, 0x00001, 0x02200,
0x02201) based on the available link BW.
The granularity of the current BW allocation policy is coarse, based on
the required link rate in the 1.62Gbs..8.1Gbps range and it may prevent
using higher resolutions all together: the display connected first will
get a share of the link BW which corresponds to its full DPRX capability
(regardless of the actual mode it uses). A subsequent display connected
will only get the remaining BW, which could be well below its full
capability.
BWA solves the above coarse granularity (reducing it to a 250Mbs..1Gps
range) and first-come/first-served issues by letting the driver request
the BW for each display on a link which reflects the actual modes the
displays use.
This patch adds the DRM core helper functions, while a follow-up change
in the patchset takes them into use in the i915 driver.
v2:
- Fix prepare_to_wait vs. wake-up cond check order in
allocate_tunnel_bw(). (Ville)

Reformat lines in kernel-doc comments, which make use of the backslash at
the end to suggest it is a multi-line comment. kernel-doc is able to
process e.g. the short description of a function properly, even if it is
across two lines.
No functional change.

Some drivers require the mapped tt pages to be decrypted. In an ideal
world this would have been handled by the dma layer, but the TTM page
fault handling would have to be rewritten to able to do that.
A side-effect of the TTM page fault handling is using a dma allocation
per order (via ttm_pool_alloc_page) which makes it impossible to just
trivially use dma_mmap_attrs. As a result ttm has to be very careful
about trying to make its pgprot for the mapped tt pages match what
the dma layer thinks it is. At the ttm layer it's possible to
deduce the requirement to have tt pages decrypted by checking
whether coherent dma allocations have been requested and the system
is running with confidential computing technologies.
This approach isn't ideal but keeping TTM matching DMAs expectations
for the page properties is in general fragile, unfortunately proper
fix would require a rewrite of TTM's page fault handling.
Fixes vmwgfx with SEV enabled.
v2: Explicitly include cc_platform.h
v3: Use CC_ATTR_GUEST_MEM_ENCRYPT instead of CC_ATTR_MEM_ENCRYPT to
limit the scope to guests and log when memory decryption is enabled.

Pull drm updates from Dave Airlie:
"This contains two major new drivers:
- imagination is a first driver for Imagination Technologies devices,
it only covers very specific devices, but there is hope to grow it
- xe is a reboot of the i915 GPU (shares display) side using a more
upstream focused development model, and trying to maximise code
sharing. It's not enabled for any hw by default, and will hopefully
get switched on for Intel's Lunarlake.
This also drops a bunch of the old UMS ioctls. It's been dead long
enough.
amdgpu has a bunch of new color management code that is being used in
the Steam Deck.
amdgpu also has a new ACPI WBRF interaction to help avoid radio
interference.

The helper is generic, it doesn't use the opaque EDID type struct drm_edid
and is also used by drivers that only support non-probeable displays such
as fixed panels.
These drivers add a list of modes using drm_mode_probed_add() and then set
a preferred mode using the drm_set_preferred_mode() helper.
It seems more logical to have the helper definition in drm_modes.o instead
of drm_edid.o, since the former contains modes helper while the latter has
helpers to manage the EDID information.
Since both drm_edid.o and drm_modes.o object files are built-in the drm.o
object, there are no functional changes. But besides being a more logical
place for this helper, it could also allow to eventually make drm_edid.o
optional and not included in drm.o if only fixed panels must be supported
in a given system.

For Xe1 platforms, it's better to follow the way i915 adds the PCI IDs
to the header, so it's easier to catch up when there is an update. This
brings the same logic applied in commit 2e3c369f23 ("drm/i915/mtl:
Eliminate subplatforms") to the equivalent xe header.
The end result of this header for Xe1 platforms is now in sync with i915
as of commit 5032c607e8 ("drm/i915: ATS-M device ID update"). This can
be seen by
$ git show 5032c607e886:include/drm/i915_pciids.h > a.h
$ git diff --color-words --no-index a.h include/drm/xe_pciids.h

The current documentation of drm_atomic_state says that it's the "global
state object". This is confusing since, while it does contain all the
objects affected by an update and their respective states, if an object
isn't affected by this update it won't be part of it.
Thus, it's not truly a "global state", unlike object state structures
that do contain the entire state of a given object.

Commits 63e83c1dba ("drm: Consolidate connector arrays in
drm_atomic_state"), b8b5342b69 ("drm: Consolidate plane arrays in
drm_atomic_state") and 5d943aa6c0 ("drm: Consolidate crtc arrays in
drm_atomic_state") moved the object pointer and their state pointer to
an intermediate structure storing both.
The CRTC commit didn't update the doc of the crtcs field to reflect
that, and the doc for the planes and connectors fields mention that they
are pointers to an array of structures with per-$OBJECT data.
The private_objs field was added later on by commit b430c27a7d ("drm:
Add driver-private objects to atomic state") reusing the same sentence
than the crtcs field, probably due to copy and paste.
While these fields are indeed pointers to an array, each item of that
array contain a pointer to the object structure affected by the update,
and its old and new state. There's no per-object data there, and there's
more than just a pointer to the objects.
Let's rephrase those fields a bit to better match the current situation.

Commit 63e83c1dba ("drm: Consolidate connector arrays in
drm_atomic_state") removed the connector_states field but didn't remove
its mention in the num_connectors documentation.
