drm_mode_create_lease
Creates a lease for a list of drm mode objects, returning an
fd for the new drm_master and a 64-bit identifier for the lessee
drm_mode_list_lesees
List the identifiers of the lessees for a master file
drm_mode_get_lease
List the leased objects for a master file
drm_mode_revoke_lease
Erase the set of objects managed by a lease.
This should suffice to at least create and query leases.
Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>:
* query ioctls only query the master associated with
the provided file.
* 'mask_lease' value has been removed

* Add revoke ioctl.
Changes for v4 suggested by Dave Airlie <airlied@gmail.com>
* Expand on the comment about the magic use of &drm_lease_idr_object
* Pad lease ioctl structures to align on 64-bit boundaries
Changes for v5 suggested by Dave Airlie <airlied@gmail.com>
* Check for non-negative object_id in create_lease to avoid debug
output from the kernel.
Changes for v6 provided by Dave Airlie <airlied@gmail.com>
* For non-universal planes add primary/cursor planes to lease
If we aren't exposing universal planes to this userspace client,
and it requests a lease on a crtc, we should implicitly export the
primary and cursor planes for the crtc.
If the lessee doesn't request universal planes, it will just see
the crtc, but if it does request them it will then see the plane
objects as well.
This also moves the object look ups earlier as a side effect, so
we'd exit the ioctl quicker for non-existant objects.
* Restrict leases to crtc/connector/planes.
This only allows leasing for objects we wish to allow.
Changes for v7 provided by Dave Airlie <airlied@gmail.com>
* Check pad args are 0
* Check create flags and object count are valid.
* Check return from fd allocation
* Refactor lease idr setup and add some simple validation
* Use idr_mutex uniformly (Keith)

This provides new data structures to hold "lease" information about
drm mode setting objects, and provides for creating new drm_masters
which have access to a subset of the available drm resources.
An 'owner' is a drm_master which is not leasing the objects from
another drm_master, and hence 'owns' them.
A 'lessee' is a drm_master which is leasing objects from some other
drm_master. Each lessee holds the set of objects which it is leasing
from the lessor.
A 'lessor' is a drm_master which is leasing objects to another
drm_master. This is the same as the owner in the current code.
The set of objects any drm_master 'controls' is limited to the set of
objects it leases (for lessees) or all objects (for owners).
Objects not controlled by a drm_master cannot be modified through the
various state manipulating ioctls, and any state reported back to user
space will be edited to make them appear idle and/or unusable. For
instance, connectors always report 'disconnected', while encoders
report no possible crtcs or clones.
The full list of lessees leasing objects from an owner (either
directly, or indirectly through another lessee), can be searched from
an idr in the drm_master of the owner.
Changes for v2 as suggested by Daniel Vetter <daniel.vetter@ffwll.ch>:
* Sub-leasing has been disabled.
* BUG_ON for lock checking replaced with lockdep_assert_held
* 'change' ioctl has been removed.
* Leased objects can always be controlled by the lessor; the
'mask_lease' flag has been removed
* Checking for leased status has been simplified, replacing
the drm_lease_check function with drm_lease_held.
Changes in v3, some suggested by Dave Airlie <airlied@gmail.com>
* Add revocation. This allows leases to be effectively revoked by
removing all of the objects they have access to. The lease itself
hangs around as it's hanging off a file.
* Free the leases IDR when the master is destroyed
* _drm_lease_held should look at lessees, not lessor
* Allow non-master files to check for lease status
Changes in v4, suggested by Dave Airlie <airlied@gmail.com>
* Formatting and whitespace changes
Changes in v5 (airlied)
* check DRIVER_MODESET before lease destroy call
* check DRIVER_MODESET for lease revoke (Chris)
* Use idr_mutex uniformly for all lease elements of struct drm_master. (Keith)

These provide crtc-id based functions instead of pipe-number, while
also offering higher resolution time (ns) and wider frame count (64)
as required by the Vulkan API.
v2:
* Check for DRIVER_MODESET in new crtc-based vblank ioctls
Failing to check this will oops the driver.
* Ensure vblank interupt is running in crtc_get_sequence ioctl
The sequence and timing values are not correct while the
interrupt is off, so make sure it's running before asking for
them.
* Short-circuit get_sequence if the counter is enabled and accurate
Steal the idea from the code in wait_vblank to avoid the
expense of drm_vblank_get/put
* Return active state of crtc in crtc_get_sequence ioctl
Might be useful for applications that aren't in charge of
modesetting?
* Use drm_crtc_vblank_get/put in new crtc-based vblank sequence ioctls
Daniel Vetter prefers these over the old drm_vblank_put/get
APIs.

Place drm_event_vblank in a new union that includes that and a bare
drm_event structure. This will allow new members of that union to be
added in the future without changing code related to the existing vbl
event type.
Assignments to the crtc_id field are now done when the event is
allocated, rather than when delievered. This way, delivery doesn't
need to have the crtc ID available.
v2:
* Remove 'dev' argument from create_vblank_event
It wasn't being used anyways, and if we need it in the future,
we can always get it from crtc->dev.
* Check for MODESETTING before looking for crtc in queue_vblank_event
UMS drivers will oops if we try to get a crtc, so make sure
we're modesetting before we try to find a crtc_id to fill into
the event.

(cherry picked from commit dc695b85fde88eca3ef3b03fcd82f15b6bc6e462)
This modifies the datatypes used by the vblank code to provide 64 bits
of vblank count.
The driver interfaces have been left using 32 bits of vblank count;
all of the code necessary to widen that value for the user API was
already included to handle devices returning fewer than 32-bits.
This will provide the necessary datatypes for the Vulkan API.
v2:
* Re-write wait_vblank ioctl to ABSOLUTE sequence
When an application uses the WAIT_VBLANK ioctl with RELATIVE
or NEXTONMISS bits set, the target vblank interval is updated
within the kernel. We need to write that target back to the
ioctl buffer and update the flags bits so that if the wait is
interrupted by a signal, when it is re-started, it will target
precisely the same vblank count as before.
* Leave driver API with 32-bit vblank count
v3:
* Rebase on top of Arnd Bergmann's patch which had
the switch to ktime_t parts.

The drm vblank handling uses 'timeval' to store timestamps in either
monotonic or wall-clock time base. In either case, it reads the current
time as a ktime_t in get_drm_timestamp() and converts it from there.
This is a bit suspicious, as users of 'timeval' often suffer from
the time_t overflow in y2038. I have gone through this code and
found that it is unlikely to cause problems here:
- The user space ABI does not use time_t or timeval, but uses
'u32' and 'long' as the types. This means at least that rebuilding
user programs against a new libc with 64-bit time_t does not
change the ABI.
- As of commit c61eef726a ("drm: add support for monotonic vblank
timestamps") in linux-3.8, the monotonic timestamp is the default
and can only get reverted to wall-clock through a module-parameter.
- With the default monotonic timestamps, there is no problem at all.
- The drm_wait_vblank_ioctl() interface is alway safe on 64-bit
architectures, on 32-bit it might overflow the 'long' timestamps
in 2038 with wall-clock timestamps.
- The event handling uses 'u32' seconds, which overflow in 2106
on both 32-bit and 64-bit machines, when wall-clock timestamps
are used.
- The effect of overflowing either of the two is only temporary
(during the overflow, and is likely to keep working again
afterwards. It is likely the same problem as observing a
'settimeofday()' call, which was the reason for moving to the
monotonic timestamps in the first place.
Overall, this seems good enough, so my patch removes the use of
'timeval' from the vblank handling altogether and uses ktime_t
consistently, except for the part where we copy the data to user
space structures in the existing format.

Initial pull request for DC support. We've completed a substantial amount of
the cleanup and restructuring in our TODO. There are a few additional
cleanups that we are continuing to work on, but I don't think there are any
showstoppers remaining. We've tried to maintain most of the history for bisect
purposes. Harry made sure all the commits build. We've enabled DC for vega10
and Raven. Pre-vega10 parts can be enabled via module parameter (amdgpu.dc=1),
but are not enabled by default at this point until we get further testing
upstream.
This code provides atomic modesetting support for DCE8 (CIK), DCE10 (Tonga,

Commit 669c9215af ("drm/atomic: Make async plane update checks work as
intended, v2.") assumed incorrectly that if only 1 plane is matched in
the loop, the variables will be set to that plane. In reality we reset
them to NULL every time a new plane was iterated. This behavior is
surprising, so fix this by making the for loops only assign the
variables on a match.
When we have not added all the planes/crtc/connector to the state, and
there's a few NULL ones after the last one we iterated, te assumption
is broken that the pointers will hold the values from the last loop
iteration, which holds true for all other for_each macros we're using.
Except of course the iterator pointer itself, but that one really is
entirely internal.

When we want to make drm_atomic_commit interruptible, there are a lot of
places that call the lock function, which we don't have control over.
Rather than trying to convert every single one, it's easier to toggle
interruptible waiting per acquire_ctx. If drm_modeset_acquire_init is
called with DRM_MODESET_ACQUIRE_INTERRUPTIBLE, then we will perform
interruptible waits in drm_modeset_lock and drm_modeset_backoff.
Changes since v1:
- Fix locking example in drm_modeset_lock.c to be compatible
with interruptible waiting (xexaxo) and make it default.
Uninterruptible waiting shouldn't happen except in corner cases,
but the example will still apply if the flag is removed.
- Add drm_modeset_lock_single_interruptible() to documentation.
- Fix dead link to removed drm_modeset_lock_interruptible() in
drm_modeset_lock().

The POWER_DOWN_PHY and POWER_UP_PHY sideband message transactions allow
the source to reqest any node in a mst path or a whole path to be
powered down or up. This allows drivers to target a specific sink in the
MST topology, an improvement over just power managing the imediate
downstream device. Secondly, since the request-reply protocol waits for an
ACK, we can be sure that a downstream sink has enough time to respond to a
power up/down request.

Allow interval trees to quickly check for overlaps to avoid unnecesary
tree lookups in interval_tree_iter_first().
As of this patch, all interval tree flavors will require using a
'rb_root_cached' such that we can have the leftmost node easily
available. While most users will make use of this feature, those with
special functions (in addition to the generic insert, delete, search
calls) will avoid using the cached option as they can do funky things
with insertions -- for example, vma_interval_tree_insert_after().

By always keeping track of the last commit in plane_state, we know
whether there is an active update on the plane or not. With that
information we can reject the fast update, and force the slowpath
to be used as was originally intended.
We cannot use plane_state->crtc->state here, because this only mentions
the most recent commit for the crtc, but not the planes that were part
of it. We specifically care about what the last commit involving this
plane is, which can only be tracked with a pointer in the plane state.
Changes since v1:
- Clean up the whole function here, instead of partially earlier.
- Add mention in the commit message why we need commit in plane_state.
- Swap plane->state in intel_legacy_cursor_update, instead of
reassigning all variables. With this commit We know that the cursor
is not part of any active commits so this hack can be removed.

[mlankhorst: Amend commit for merge conflicts with drm-intel]
Currently we neatly track the crtc state, but forget to look at
plane/connector state.
When doing a nonblocking modeset, immediately followed by a setprop
before the modeset completes, the setprop will see the modesets new
state as the old state and free it.
This has to be solved by waiting for hw_done on the connector, even
if it's not assigned to a crtc. When a connector is unbound we take
the last crtc commit, and when it stays unbound we create a new
fake crtc commit for that gets signaled on hw_done for all the
planes/connectors.
We wait for it the same way as we do for crtc's, which will make
sure we never run into a use-after-free situation.

- Only create a single disable commit. (danvet)

The atomic exchange operation in drm_syncobj_replace_fence is sufficient
for the case where it races with itself. However, if you have a race
between a replace_fence and dma_fence_get(syncobj->fence), you may end
up with the entire replace_fence happening between the point in time
where the one thread gets the syncobj->fence pointer and when it calls
dma_fence_get() on it. If this happens, then the reference may be
dropped before we get a chance to get a new one. The new helper uses
dma_fence_get_rcu_safe to get rid of the race.
This is also needed because it allows us to do a bit more than just get
a reference in drm_syncobj_fence_get should we wish to do so.

The reason behind the original indirection through the helper
functions was to allow existing drivers to overwrite how they handle
properties. For example when a vendor-specific userspace had
expectations that didn't match atomic. That seemed likely, since
atomic is standardizing a _lot_ more of the behaviour of a kms driver.
But 20 drivers later there's no such need at all. Worse, this forces
all drivers to hook up the default behaviour, breaking userspace if
they forget to do that. And it forces us to export a bunch of core
function just for those helpers.
And finally, these helpers are the last places using
drm_atomic_legacy_backoff() and the implicit acquire_ctx.
This patch here just implements the new behaviour and updates the
docs. Follow-up patches will garbage-collect all the dead code.
v2: Fixup docs even better!
v3: Make it actually work ...
v4: Drop the uses_atomic_modeset() checks from the previous patch
again, since they're now moved up in the callchain.

FB helper code falls back to a 1024x768 mode if no outputs are connected
or don't report back any modes upon initialization. This can be annoying
because outputs that are added to FB helper later on can't be used with
FB helper if they don't support a matching mode.
The fallback is in place because VGA connectors can happen to report an
unknown connection status even when they are in fact connected.
Some drivers have custom solutions in place to defer FB helper setup
until at least one output is connected. But the logic behind these
solutions is always the same and there is nothing driver-specific about
it, so a better alterative is to fix the FB helper core and add support
for all drivers automatically.
This patch adds support for deferred FB helper setup. It checks all the
connectors for their connection status, and if all of them report to be
disconnected marks the FB helper as needing deferred setup. Whet setup
is deferred, the FB helper core will automatically retry setup after a
hotplug event, and it will keep trying until it succeeds.
v2: Rebase onto my entirely reworked fbdev helper locking. One big
difference is that this version again drops&reacquires the fbdev lock
(which is now fb_helper->lock, but before this patch series it was
mode_config->mutex), because register_framebuffer must be able to
recurse back into fbdev helper code for the initial screen setup.
v3: __drm_fb_helper_initial_config must hold fb_helper->lock upon
return, I've fumbled that in the deferred setup case (Liviu).
v4: I was blind, redo this all. __drm_fb_helper_initial_config
shouldn't need to reacquire fb_helper->lock, that just confuses
callers. I myself got confused by kernel_fb_helper_lock and somehow
thought it's the same as fb_helper->lock. Tsk.
Also simplify the logic a bit (we don't need two functions to probe
connectors), we can stick much closer to the existing code. And update
some comments I've spotted that are outdated.
v5: Don't pass -EAGAIN to drivers, it's just an internal error code
(Liviu).
v6: Add _and_unlock suffix to clarify locking (Maarten)

HDMI 2.0 spec adds support for YCBCR420 sub-sampled output.
CEA-861-F adds two new blocks in EDID's CEA extension blocks,
to provide information about sink's YCBCR420 output capabilities.
These blocks are:
- YCBCR420vdb(YCBCR 420 video data block):
This block contains VICs of video modes, which can be sopported only
in YCBCR420 output mode (Not in RGB/YCBCR444/422. Its like a normal
SVD block, valid for YCBCR420 modes only.
- YCBCR420cmdb(YCBCR 420 capability map data block):
This block gives information about video modes which can support
YCBCR420 output mode also (along with RGB,YCBCR444/422 etc) This
block contains a bitmap index of normal svd videomodes, which can
support YCBCR420 output too.
So if bit 0 from first vcb byte is set, first video mode in the svd
list can support YCBCR420 output too. Bit 1 means second video mode
from svd list can support YCBCR420 output too, and so on.
This patch adds two bitmaps in display's hdmi_info structure, one each
for VCB and VDB modes. If the source is HDMI 2.0 capable, this patch
adds:
- VDB modes (YCBCR 420 only modes) in connector's mode list, also makes
an entry in the vdb_bitmap per vic.
- VCB modes (YCBCR 420 also modes) only entry in the vcb_bitmap.

Review comments from Emil:
- Use 1ULL<<i instead of 1<<i to make sure the output is 64bit.
- Use the suggested method for updating dbmap.
- Add documentation for YCBCR420_vcb_map to fix kbuild warning.
Review comments from Ville:
- Do not expose the YCBCR420 flags in uabi layer, keep it internal.
- Save a map of YCBCR420 modes for future reference.
- Check db length before trying to parse extended tag.
- Add a warning if there are > 64 modes in capability map block.
- Use y420cmdb in function names and macros while dealing with vcb
to be aligned with spec.
- Move the display information parsing block ahead of mode parsing
blocks.
V3: Addressed design/review comments from Ville
- Do not add flags in video modes, else we have to expose them to user
- There should not be a UABI change, and kernel should detect the
choice of the output based on type of mode, and the bitmaps.
- Use standard bitops from kernel bitmap header, instead of calculating
bit positions manually.

- Do not add print about YCBCR 420 modes
- Fix indentation in few places
- Move ycbcr420_dc_modes in next patch, where its used

V5: Addressed review comments from Ville:
- Add the patch which cleans up the current EXTENDED_TAG usage
- Make y420_cmdb_map u64

YCBCR420 modes are supported only on HDMI 2.0 capable sources.
This patch adds:
- A drm helper to validate YCBCR420-only mode on a particular
connector. This function will help pruning the YCBCR420-only
modes from the connector's modelist.
- A bool variable (ycbcr_420_allowed) in the drm connector structure.
While handling the EDID from HDMI 2.0 sinks, its important to know
if the source is capable of handling YCBCR420 output, so that no
YCBCR 420 modes will be listed for sources which can't handle it.
A driver should set this variable if it wants to see YCBCR420 modes
in the modedb.
V5: Introduced the patch in series.
V6: Squashed two patches (validate YCBCR420 and add YCBCR420
identifier)
V7: Addressed review comments from Vile:
- Move this patch before we add 420 modes from EDID.
- No need for drm_valid_cea_vic() check, function back to non-static.
- Update MODE_STATUS with NO_420 condition.
- Introduce y420_vdb_modes variable in this patch

HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64).
For any other mode, the VIC filed in AVI infoframes should be 0.
HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is
extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected
sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a
HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function
drm_hdmi_avi_infoframe_from_display_mode but to make sure there is
no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch:
- checks if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
- VIC for 4K modes for HDMI 1.4 sinks
- S3D information for S3D modes
As CEA-861-F has already defined VICs for 4K videomodes, this
patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
until the mode is 3D.

The function has little to do with atomic, it's just where it has so
far been needed. So, rename it to drm_property_replace_blob, move it
to drm_property.c and export it.
Change the semantics to return whether the blob was replaced instead
of using an extra argument for that.

Introduce a new top-level lock for the FB helper code. This will allow
better locking granularity and avoid the need to abuse modeset locking
for this purpose instead.
This patch just adds the new lock everywhere we currently grab
mode_config->mutex (explicitly, or through drm_modeset_lock_all).
Follow-up patches will push the kms locking down into only the places
that need it.
v2:
- use lockdep_assert_held
- use drm_fb_helper_for_each_connector where possible
- use the new top-level lock consistently, i.e. in all the places
we're currently acquiring mode_config.mutex.
- small polish to the kerneldoc

In some cases, like cursor updates, it is interesting to update the
plane in an asynchronous fashion to avoid big delays. The current queued
update could be still waiting for a fence to signal and thus block any
subsequent update until its scan out. In cases like this if we update the
cursor synchronously through the atomic API it will cause significant
delays that would even be noticed by the final user.
This patch creates a fast path to jump ahead the current queued state and
do single planes updates without going through all atomic steps in
drm_atomic_helper_commit(). We take this path for legacy cursor updates.
For now only single plane updates are supported, but we plan to support
multiple planes updates and async PageFlips through this interface as well
in the near future.

The old state is useful for drivers that need to perform operations at
enable time that depend on the transition between the old and new
states.
While at it, rename the operation to .atomic_enable() to be consistent
with .atomic_disable(), as the .enable() operation is used by atomic
helpers only.

There's no reason for drivers to call this, and all the ones I've
removed looked very fishy:
- Proper quiescenting of the vblank machinery should be done by
calling drm_crtc_vblank_off(), which is best done by shutting down
the entire display engine with drm_atomic_helper_shutdown.
- Releasing of allocated memory is done by the core already, it calls
drm_vblank_cleanup as a fallback.
- drm_vblank_cleanup also has checks for drivers which forget to clean
up vblank interrupts.
This essentially reverts

drm/radeon/kms: Don't try to enable IRQ if we have no handler installed
Afaict from digging around in old code, this was needed to avoid
blowing up in the ums fallback, and has stopped serving it's purpose
long ago - if irq init fails, the driver fails to load, and there's
really no way to blow up anymore.
Long story short, this was most likely a small ums compat/fallback
hack that became a thing of it's own and got cargo-cult duplicated all
over the drm codebase for essentially no gain at all.
v2: Mention that for drivers with a ->release callback cleanup is
handled by drm_dev_fini() (Thierry).

Face the fact, there are Display Port sink and branch devices out there
in the wild that don't follow the Display Port specifications, or they
have bugs, or just otherwise require special treatment. Start a common
quirk database the drivers can query based on the DP device
identification. At least for now, we leave the workarounds for the
drivers to implement as they see fit.
For starters, add a branch device that can't handle full 24-bit main
link Mdiv and Ndiv main link attributes properly. Naturally, the
workaround of reducing main link attributes for all devices ended up in
regressions for other devices. So here we are.
