Add the WRITEBACK_OUT_FENCE_PTR property to writeback connectors, to
enable userspace to get a fence which will signal once the writeback is
complete. It is not allowed to request an out-fence without a
framebuffer attached to the connector.
A timeline is added to drm_writeback_connector for use by the writeback
out-fences.
In the case of a commit failure or DRM_MODE_ATOMIC_TEST_ONLY, the fence
is set to -1.
Changes from v2:
- Rebase onto Gustavo Padovan's v9 explicit sync series
- Change out_fence_ptr type to s32 __user *
- Set *out_fence_ptr to -1 in drm_atomic_connector_set_property
- Store fence in drm_writeback_job
Gustavo Padovan:
- Move out_fence_ptr out of connector_state
- Signal fence from drm_writeback_signal_completion instead of
in driver directly
Changes from v3:
- Rebase onto commit 7e9081c5aa ("drm/fence: fix memory overwrite

for real this time.)

Writeback connectors represent writeback engines which can write the
CRTC output to a memory framebuffer. Add a writeback connector type and
related support functions.
Drivers should initialize a writeback connector with
drm_writeback_connector_init() which takes care of setting up all the
writeback-specific details on top of the normal functionality of
drm_connector_init().
Writeback connectors have a WRITEBACK_FB_ID property, used to set the
output framebuffer, and a WRITEBACK_PIXEL_FORMATS blob used to expose the
supported writeback formats to userspace.
When a framebuffer is attached to a writeback connector with the
WRITEBACK_FB_ID property, it is used only once (for the commit in which
it was included), and userspace can never read back the value of
WRITEBACK_FB_ID. WRITEBACK_FB_ID can only be set if the connector is
attached to a CRTC.
Changes since v1:
- Added drm_writeback.c + documentation
- Added helper to initialize writeback connector in one go
- Added core checks
- Squashed into a single commit
- Dropped the client cap
- Writeback framebuffers are no longer persistent
Changes since v2:
Daniel Vetter:
- Subclass drm_connector to drm_writeback_connector
- Relax check to allow CRTC to be set without an FB
- Add some writeback_ prefixes
- Drop PIXEL_FORMATS_SIZE property, as it was unnecessary
Gustavo Padovan:
- Add drm_writeback_job to handle writeback signalling centrally
Changes since v3:
- Rebased
- Rename PIXEL_FORMATS -> WRITEBACK_PIXEL_FORMATS
Chances since v4:
- Embed a drm_encoder inside the drm_writeback_connector to
reduce the amount of boilerplate code required from the drivers
that are using it.
Changes since v5:
- Added Rob Clark's atomic_commit() vfunc to connector helper
funcs, so that writeback jobs are committed from atomic helpers
- Updated create_writeback_properties() signature to return an
error code rather than a boolean false for failure.
- Free writeback job with the connector state rather than when
doing the cleanup_work()
Changes since v7:
- fix extraneous use of out_fence that is only introduced in a
subsequent patch.
Changes since v8:
- whitespace changes pull from subsequent patch
Changes since v9:
- Revert the v6 changes that free the writeback job in the connector
state cleanup and return to doing it in the cleanup_work() function

I've done a lot of history digging. The first signs of this
optimization was introduced in i915:
commit 25067bfc06
Author: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
Date: Wed Sep 10 12:03:17 2014 -0300
drm/i915: pin sprite fb only if it changed
without much justification. Pinning already pinned stuff is real cheap
(it's just obj->pin_count++ really), and the missing implicit sync was
entirely forgotten about it seems. It's at least not mentioned
anywhere it the commit message.
It was also promptly removed shortly afterwards in
commit ea2c67bb4a
Author: Matt Roper <matthew.d.roper@intel.com>
Date: Tue Dec 23 10:41:52 2014 -0800
drm/i915: Move to atomic plane helpers (v9)
again without really mentioning the side-effect that plane updates
with the same fb now again obey implicit syncing.
Note that this only ever applied to the plane_update hook, all other
legacy entry points (set_base, page_flip) always obeyed implicit sync
in the drm/i915 driver.
The real source of this code here seems to be msm, copied to vc4, then
copied to tinydrm. I've also tried to dig around in all available msm
sources, but the corresponding check for fb != old_fb is present ever
since the initial merge in
commit cf3a7e4ce0
Author: Rob Clark <robdclark@gmail.com>
Date: Sat Nov 8 13:21:06 2014 -0500
drm/msm: atomic core bits
The only older version I've found of msm atomic code predates the
atomic helpers, and so didn't even use any of this. It also does not
have a corresponding check (because it simply did no implicit sync at
all).
I've chatted with Rob on irc, and he didn't remember the reason for
this either.
Note we had epic amounts of fun with too much syncing against
_vblank_, especially around cursor updates. But I don't ever
discussing a need for less syncing against implicit fences.
Also note that explicit fencing allows you to sidetrack all of this,
at least for all the drivers correctly implemented using
drm_atomic_set_fence_for_plane().
Given that it seems to be an accident of history, and that big drivers
like i915 (and also nouveau it seems, I didn't follow the
amdgpu/radeon sync code to figure this out properly there) never have
done it, let's remove this.

The vop irq is shared between vop and iommu and irq probing in the
iommu driver moved to the probe function recently. This can in some
cases lead to a stall if the irq is triggered while the vop driver
still has it disabled, but the vop irq handler gets called.
But there is no real need to disable the irq, as the vop can simply
also track its enabled state and ignore irqs in that case.
For this we can simply check the power-domain state of the vop,
similar to how the iommu driver does it.
So remove the enable/disable handling and add appropriate condition
to the irq handler.
changes in v2:
- move to just check the power-domain state
- add clock handling
changes in v3:
- clarify comment to speak of runtime-pm not power-domain
changes in v4:
- address Marc's comments (clk-enable WARN_ON and style improvement)

The device node iterators perform an of_node_get on each iteration, so a
jump out of the loop requires an of_node_put.

This tag contains some small RISC-V updates I'd like to target for 4.18.
They are all fairly small this time. Here's a short summary, there's
more info in the commits/merges.
* A fix to __clear_user to respect the passed arguments.
* Enough support for the perf subsystem to work with RISC-V's ISA
defined performance counters.
* Support for sparse and cleanups suggested by it.
* Support for R_RISCV_32 (a relocation, not the 32-bit ISA).
* Some MAINTAINERS cleanups.
* The addition of CONFIG_HVC_RISCV_SBI to our defconfig, as it's always
present.
I've given these a simple build+boot test.
