remove private zpos property and use instead the generic new.
zpos range is now fixed per plane type and normalized before
being using in mixer.

version 8:
- move drm_blend.o from drm-y to drm_kms_helper-y to avoid
EXPORT_SYMBOL(drm_atomic_helper_normalize_zpos)
- remove dead function declarations in drm_crtc.h
version 7:
- remove useless EXPORT_SYMBOL()
- better z-order wording in Documentation
version 6:
- add zpos in gpu documentation file
- merge Ville patch about zpos initial value and API improvement.
I have split Ville patch between zpos core and drivers
version 5:
- remove zpos range check and comeback to 0 to N-1
normalization algorithm
version 4:
- make sure that normalized zpos value is stay
in the defined property range and warn user if not
This patch adds support for generic plane's zpos property property with
well-defined semantics:
- added zpos properties to plane and plane state structures
- added helpers for normalizing zpos properties of given set of planes
- well defined semantics: planes are sorted by zpos values and then plane
id value if zpos equals
Normalized zpos values are calculated automatically when generic
muttable zpos property has been initialized. Drivers can simply use
plane_state->normalized_zpos in their atomic_check and/or plane_update
callbacks without any additional calls to DRM core.
Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>
Compare to Marek's original patch zpos property is now specific to each
plane and no more to the core.
Normalize function take care of the range of per plane defined range
before set normalized_zpos.

Restore the correct behaviour (as in check msg.reply) when aux
->transfer() returns 0. It got removed in
commit 82922da39190 ("drm/dp_helper: Retry aux transactions on all errors")
Now I can actually dump the "entire" DPCD on a Dell UP2314Q with
ddrescue. It has some offsets in the DPCD that can't be read
for some resaon, all you get is defers. Previously ddrescue would
just give up at the first unredable offset on account of
read() returning 0 means EOF. Here's the ddrescue log
for the interested:

This reverts commit 041824ee25cfc535ba2d9a22c217df735ea2471e.
We have latency issues that might impact the performance: #96606.
and hangs and loading issues on resume after S4: #96526.
This is also blocking a platform milestone so let's disable
this for now while we make sure we don't have any more loading
issue, or related basic hangs and it pass BAT for real in all
platofmrs.
In case BAT is wrong let's first fix BAT before re-enable it here.

Setting a write-back cache policy in the MOCS entry definition also
implies snooping, which has a considerable overhead. This is
unexpected for a few reasons:
- From user-space's point of view since it didn't want a coherent
surface (it didn't set the buffer as such via the set caching IOCTL).
- There is a separate MOCS entry field for snooping (which we never
set).
- This MOCS table is about caching in (e)LLC and there is no (e)LLC on
BXT. There is a separate table for L3 cache control.
Considering the above the current behavior of snooping looks like an
unintentional side-effect of the WB setting. Changing it to be LLC-UC
gets rid of the snooping without any ill-effects. For a coherent
surface the application would use a separate MOCS entry at index 1 and
call the set caching IOCTL to setup the PTE entries for the
corresponding buffer to be snooped. In the future we could also add a
new MOCS entry for coherent surfaces.
This resulted in 70% improvement in synthetic texturing benchmarks.
Kudos to Valtteri Rantala, Eero Tamminen and Michael T Frederick and
Ville who helped to narrow the source of problem to the kernel and to
the snooping behaviour in particular.
With a follow-up change to adjust the 3rd entry value
igt/gem_mocs_settings is passing after this change.
v2:
- Rebase on v2 of patch 1/2.
v3:
- Set the entry as LLC uncached instead of PTE-passthrough. This way
we also keep snooping disabled, but we also make the cacheability/
coherency setting indepent of the PTE which is managed by the
kernel. (Chris)

Use named struct initializers for clarity. Also fix the target cache
definition to reflect its role in GEN9 onwards. On GEN8 a TC value of 0
meant ELLC but on GEN9+ it means the TC and LRU controls are taken from
the PTE.
No functional change, igt/gem_mocs_settings still passing after this
change.
v2: (Chris)
- Add back the hexa literals for the entries.
Add note that igt/gem_mocs_settings still passes.

The drm_irq docs want one function from drmP.h, but that one is a
serious mess. Extract it, and while at it improve the docs a bit.
There's a bit a header loop issue since core data structures like
drm_device and drm_driver aren't in their own headers yet, which means
the drm_irq.h include in drmP.h needs to be in just the right spot :(
Also noticed that drm_vblank_crtc->last_wait is entirely unused,
remove it.

This has now been removed from all drivers as it is performed centrally
as a part of device unregistration for modesetting drivers. With the last
user gone, we can unexport it from the DRM module. That requires us to

drm-next
This is an update to the previous drm bridge pull request. The ADV7511
driver's conversion from slave encoder to bridge meant that its users
(the rcar-du kms driver) should use the bridge interface too. This pull
request now also contains a commit that updates the rcar-du's hdmi encoder
interface from slave encoder to bridge.
The other updates are as before:
- Converts the ADV7511 i2c slave encoder driver to a bridge driver.
Adds support for the ADV7533 bridge chip.
- Add bridge driver for TC358767 (DSI/DPI to eDP) encoder chips.

The i915 driver is now using atomic properties and atomic commit
to handle the legacy set gamma IOCTL. However, if the driver is
configured without atomic (nuclear_pageflip = false), it won't
update the legacy properties for degamma_lut, gamma_lut and ctm
leaving them out of sync with the atomic version of the properties.
Until the driver is full atomic, make sure we update the non-atomic
version of the properties.
v2: Update the comment with a FIXME. (Daniel)
v3: Update arguments of the gamma_set vfunc (Lionel)
v4: Fixed vfunc prototype (Lionel)

Unfortunately, there's two situations where we lose hpd right now:
- Runtime suspend
- When we've shut off all of the power wells on Valleyview/Cherryview
While it would be nice if this didn't cause issues, this has the
ability to get us in some awkward states where a user won't be able to
get their display to turn on. For instance; if we boot a Valleyview
system without any monitors connected, it won't need any of it's power
wells and thus shut them off. Since this causes us to lose HPD, this
means that unless the user knows how to ssh into their machine and do a
manual reprobe for monitors, none of the monitors they connect after
booting will actually work.
Eventually we should come up with a better fix then having to enable
polling for this, since this makes rpm a lot less useful, but for now
the infrastructure in i915 just isn't there yet to get hpd in these
situations.
Changes since v1:
- Add comment explaining the addition of the if
(!mode_config->poll_running) in intel_hpd_init()
- Remove unneeded if (!dev->mode_config.poll_enabled) in
i915_hpd_poll_init_work()
- Call to drm_helper_hpd_irq_event() after we disable polling
- Add cancel_work_sync() call to intel_hpd_cancel_work()
Changes since v2:
- Apparently dev->mode_config.poll_running doesn't actually reflect
whether or not a poll is currently in progress, and is actually used
for dynamic module paramter enabling/disabling. So now we instead
keep track of our own poll_running variable in dev_priv->hotplug
- Clean i915_hpd_poll_init_work() a little bit
Changes since v3:
- Remove the now-redundant connector loop in intel_hpd_init(), just
rely on intel_hpd_poll_enable() for setting connector->polled
correctly on each connector
- Get rid of poll_running
- Don't assign enabled in i915_hpd_poll_init_work before we actually
lock dev->mode_config.mutex
- Wrap enabled assignment in i915_hpd_poll_init_work() in READ_ONCE()
for doc purposes
- Do the same for dev_priv->hotplug.poll_enabled with WRITE_ONCE in
intel_hpd_poll_enable()
- Add some comments about racing not mattering in intel_hpd_poll_enable
Changes since v4:
- Rename intel_hpd_poll_enable() to intel_hpd_poll_init()
- Drop the bool argument from intel_hpd_poll_init()
- Remove redundant calls to intel_hpd_poll_init()
- Rename poll_enable_work to poll_init_work
- Add some kerneldoc for intel_hpd_poll_init()
- Cross-reference intel_hpd_poll_init() in intel_hpd_init()
- Just copy the loop from intel_hpd_init() in intel_hpd_poll_init()
Changes since v5:
- Minor kerneldoc nitpicks

One of the things preventing us from using polling is the fact that
calling valleyview_crt_detect_hotplug() when there's a VGA cable
connected results in sending another hotplug. With polling enabled when
HPD is disabled, this results in a scenario like this:
- We enable power wells and reset the ADPA
- output_poll_exec does force probe on VGA, triggering a hpd
- HPD handler waits for poll to unlock dev->mode_config.mutex
- output_poll_exec shuts off the ADPA, unlocks dev->mode_config.mutex
- HPD handler runs, resets ADPA and brings us back to the start
This results in an endless irq storm getting sent from the ADPA
whenever a VGA connector gets detected in the middle of polling.
Somewhat based off of the "drm/i915: Disable CRT HPD around force
trigger" patch Ville Syrjälä sent a while back

While VGA hotplugging worked(ish) before, it looks like that was mainly
because we'd unintentionally enable it in
valleyview_crt_detect_hotplug() when we did a force trigger. This
doesn't work reliably enough because whenever the display powerwell on
vlv gets disabled, the values set in VLV_ADPA get cleared and
consequently VGA hotplugging gets disabled. This causes bugs such as one
we found on an Intel NUC, where doing the following sequence of
hotplugs:
- Disconnect all monitors
- Connect VGA
- Disconnect VGA
- Connect HDMI
Would result in VGA hotplugging becoming disabled, due to the powerwells
getting toggled in the process of connecting HDMI.
Changes since v3:
- Expose intel_crt_reset() through intel_drv.h and call that in
vlv_display_power_well_init() instead of
encoder->base.funcs->reset(&encoder->base);
Changes since v2:
- Use intel_encoder structs instead of drm_encoder structs
Changes since v1:
- Instead of handling the register writes ourself, we just reuse
intel_crt_detect()
- Instead of resetting the ADPA during display IRQ installation, we now
reset them in vlv_display_power_well_init()

When the input color format is YUV, we need to do some external scale
for CBCR. Like,
* In YUV420 data format:
cbcr_xscale = dst_w / src_w * 2;
cbcr_yscale = dst_h / src_h * 2;
* In YUV422 data format:
cbcr_xscale = dst_w / src_w * 2;
cbcr_yscale = dst_h / src_h;
* In YUV444 data format
cbcr_xscale = dst_w / src_w;
cbcr_yscale = dst_h / src_h;
