drm/tegra: Changes for v5.15-rc1
The bulk of these changes is a more modern ABI that can be efficiently
used on newer SoCs as well as older ones. The userspace parts for this
are available here:
- libdrm support: https://gitlab.freedesktop.org/tagr/drm/-/commits/drm-tegra-uabi-v8
- VAAPI driver: https://github.com/cyndis/vaapi-tegra-driver
In addition, existing userspace from the grate reverse-engineering
project has been updated to use this new ABI:
- X11 driver: https://github.com/grate-driver/xf86-video-opentegra
- 3D driver: https://github.com/grate-driver/grate
Other than that, there's also support for display memory bandwidth
management for various generations and a bit of cleanup.

least-significant 2 bits", not "black and white". Rename the field
accordingly. This field is not used anywhere, so just renaming it here

UAPI Changes:
- Add I915_MMAP_OFFSET_FIXED
On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid
type. On devices without local memory, this caching mode is invalid.
As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will
be used, depending on the object placement on creation. WB will be used
when the object can only exist in system memory, WC otherwise.
Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888
- Reinstate the mmap ioctl for (already released) integrated Gen12 platforms
Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is
still to sunset the IOCTL even for integrated and require using mmap_offset.
- Reject caching/set_domain IOCTLs on discrete
Expected to become immutable property of the BO
- Disallow changing context parameters after first use on Gen12 and earlier
- Require setting context parameters at creation on platforms after Gen12
Rationale (for both): Allow less dynamic changes to the context to simplify
the implementation and avoid user shooting theirselves in the foot.
- Drop I915_CONTEXT_PARAM_RINGSIZE
Userspace PR for compute-driver has not been merged
- Drop I915_CONTEXT_PARAM_NO_ZEROMAP
Userspace PR for libdrm / Beignet was never landed
- Drop CONTEXT_CLONE API
Userspace PR for Mesa was never landed
- Drop getparam support for I915_CONTEXT_PARAM_ENGINES
Only existed for symmetry wrt. setparam, never used.
- Disallow bonding of virtual engines
Drop the prep work, no hardware has been released needing it.
- (Implicit) Disable gpu relocations
Media userspace was the last userspace to still use them. They
have converted so performance can be regained with an update.

Add support for inserting syncpoint waits in the CDMA pushbuffer.
These waits need to be done in HOST1X class, while gather submitted
by the application execute in engine class.
Support is added by converting the gather list of job into a command
list that can include both gathers and waits. When the job is
submitted, these commands are pushed as the appropriate opcodes
on the CDMA pushbuffer.
Also supported are waits relative to the start of the job,
which are useful for jobs doing multiple things with an engine
that doesn't natively support pipelining.
While at it, use 32-bit waits on chips that support them.

Add a new property for jobs to enable or disable recovery i.e.
CPU increments of syncpoints to max value on job timeout. This
allows for a more solid model for hanged jobs, where userspace
doesn't need to guess if a syncpoint increment happened because
the job completed, or because job timeout was triggered.
On job timeout, we stop the channel, NOP all future jobs on the
channel using the same syncpoint, mark the syncpoint as locked
and resume the channel from the next job, if any.
The future jobs are NOPed, since because we don't do the CPU
increments, the value of the syncpoint is no longer synchronized,
and any waiters would become confused if a future job incremented
the syncpoint. The syncpoint is marked locked to ensure that any
future jobs cannot increment the syncpoint either, until the
application has recognized the situation and reallocated the
syncpoint.

Add an implementation of dma_fences based on syncpoints. Syncpoint
interrupts are used to signal fences. Additionally, after
software signaling has been enabled, a 30 second timeout is started.
If the syncpoint threshold is not reached within this period,
the fence is signalled with an -ETIMEDOUT error code. This is to
allow fences that would never reach their syncpoint threshold to
be cleaned up. The timeout can potentially be removed in the future
after job tracking code has been refactored.

Currently the SVM get_attr call allows querying, which flags are set
in the entire address range. Add the opposite query, which flags are
clear in the entire address range. Both queries can be combined in a
single get_attr call, which allows answering questions such as, "is
this address range coherent, non-coherent, or a mix of both"?

Jason Ekstrand requested a more efficient method than userptr+set-domain
to determine if the userptr object was backed by a complete set of pages
upon creation. To be more efficient than simply populating the userptr
using get_user_pages() (as done by the call to set-domain or execbuf),
we can walk the tree of vm_area_struct and check for gaps or vma not
backed by struct page (VM_PFNMAP). The question is how to handle
VM_MIXEDMAP which may be either struct page or pfn backed...
With discrete we are going to drop support for set_domain(), so offering
a way to probe the pages, without having to resort to dummy batches has
been requested.
v2:
- add new query param for the PROBE flag, so userspace can easily
check if the kernel supports it(Jason).
- use mmap_read_{lock, unlock}.
- add some kernel-doc.
v3:
- In the docs also mention that PROBE doesn't guarantee that the pages
will remain valid by the time they are actually used(Tvrtko).
- Add a small comment for the hole finding logic(Jason).
- Move the param next to all the other params which just return true.

https://gitlab.freedesktop.org/drm/msm into drm-next
An early pull for v5.15 (there'll be more coming in a week or two),
consisting of the drm/scheduler conversion and a couple other small
series that one was based one. Mostly sending this now because IIUC
danvet wanted it in drm-next so he could rebase on it. (Daniel, if
you disagree then speak up, and I'll instead include this in the main
pull request once that is ready.)
This also has a core patch to drop drm_gem_object_put_locked() now
that the last use of it is removed.

We make the following changes to the documentation of drm leases to
make it easier to reason about their usage. In particular, we clarify
the lifetime and locking rules of lease fields in drm_master:
1. Make it clear that &drm_device.mode_config.idr_mutex protects the
lease idr and list structures for drm_master. The lessor field itself
doesn't need to be protected as it doesn't change after it's set in
drm_lease_create.
2. Add descriptions for the lifetime of lessors and leases.
3. Add an overview DOC: section in drm-uapi.rst that defines the
terminology for drm leasing, and explains how leases work and why
they're used.

The drm/scheduler provides additional prioritization on top of that
provided by however many number of ringbuffers (each with their own
priority level) is supported on a given generation. Expose the
additional levels of priority to userspace and map the userspace
priority back to ring (first level of priority) and schedular priority
(additional priority levels within the ring).

On all platforms except i.MX and Rockchip, the dw-hdmi DT bindings
require a video output port connected to an HDMI sink (most likely an
HDMI connector, in rare cases another bridges converting HDMI to another
protocol). For those platforms, retrieve the next bridge and attach it
from the dw-hdmi bridge attach handler.

Implement a simple static mapping algorithm of the i915 priority levels
(int, -1k to 1k exposed to user) to the 4 GuC levels. Mapping is as
follows:
i915 level < 0 -> GuC low level (3)
i915 level == 0 -> GuC normal level (2)
i915 level < INT_MAX -> GuC high level (1)
i915 level == INT_MAX -> GuC highest level (0)
We believe this mapping should cover the UMD use cases (3 distinct user
levels + 1 kernel level).
In addition to static mapping, a simple counter system is attached to
each context tracking the number of requests inflight on the context at
each level. This is needed as the GuC levels are per context while in
the i915 levels are per request.
v2:
(Daniele)
- Add BUILD_BUG_ON to enforce ordering of priority levels
- Add missing lockdep to guc_prio_fini
- Check for return before setting context registered flag
- Map DISPLAY priority or higher to highest guc prio
- Update comment for guc_prio

There's two stages of manual upload/invalidate displays:
- just handling dirtyfb and uploading the entire fb all the time
- looking at damage clips
In the latter case we support it through fbdev emulation (with
fb_defio), atomic property, and with the dirtfy clip rects.
Make sure at least the atomic property is set up as the main official
interface for this. Ideally we'd also check that
drm_atomic_helper_dirtyfb() is used and that fbdev defio is set up,
but that's quite a bit harder to do. Ideas very much welcome.
From a cursor audit drivers seem to be getting this right mostly, but
better to make sure. At least no one is bypassing the accessor
function.
v2:
- use drm_warn_once with a meaningful warning string (José)
- don't splat in the atomic check code for everyone (intel-gfx-ci)

It's not used. Drivers should instead use the helpers anyway.
Currently both vbox and i915 hand-roll this and it's not the greatest.
vbox looks buggy, and i915 does a bit much that helpers would take
care of I think.
Also improve the kerneldocs while we're at it.

Many of the DSI flags have names opposite to their actual effects,
e.g. MIPI_DSI_MODE_EOT_PACKET means that EoT packets will actually
be disabled. Fix this by including _NO_ in the flag names, e.g.
MIPI_DSI_MODE_NO_EOT_PACKET.

Commit 71f642833284 ("ACPI: utils: Fix reference counting in
for_each_acpi_dev_match()") started doing "acpi_dev_put()" on a pointer
that was possibly NULL. That fails miserably, because that helper
inline function is not set up to handle that case.
Just make acpi_dev_put() silently accept a NULL pointer, rather than
calling down to put_device() with an invalid offset off that NULL
pointer.

Commit b10d6bca8720 ("arch, drivers: replace for_each_membock() with
for_each_mem_range()") didn't take into account that when there is
movable_node parameter in the kernel command line, for_each_mem_range()
would skip ranges marked with MEMBLOCK_HOTPLUG.
The page table setup code in POWER uses for_each_mem_range() to create
the linear mapping of the physical memory and since the regions marked
as MEMORY_HOTPLUG are skipped, they never make it to the linear map.
A later access to the memory in those ranges will fail:
