PCI_DOMAINS config should be selected for any SoCs
having more than a single PCIe controller. Without PCI_DOMAINS
config, only one PCIe controller gets registered.
Select PCI_DOMAINS in ARCH_MULTIPLATFORM if PCI is selected, since
it doesn't harm even if a platform has a single PCIe port.
Also remove PCI_DOMAINS being selected from other platform
specific configs.

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.
Using the macro makes the code more readable by helping abstract away some

Merge "drop last omap3 board files for v4.8" from Tony Lindgren:
Remove the last two legacy board-*.c files for omap3 for legacy
booting for v4.8 to allow making mach-omap2 device tree only for
v4.9.
We've had Nokia N900 and omap3 LDP board-*.c files remaining
while other omap3 devices have been device tree only for quite
a while now. Also N900 and LDP have had device tree based booting
working for years now, but few drivers for N900 were still only
working in legacy only mode until recently. With the remaining
issues out of the way, we discussed on the mailing lists that
we're finally OK to remove the remaining board-*.c files.
For the timing of this pull request, I wanted to wait until
v4.8-rc1 is out to make sure the legacy booting still works fine
after the merge window before doing it.
And for v4.8, let's not touch any other platform data in case we
still need to revert for some reason. This makes the revert just a
question of adding back the legacy board-*.c files.
Then if no issues, we can remove the unused remaining platform
data later on for v4.9.

Let's drop the last two remaining omap3 legacy boot board files.
Let's only use the device tree based booting known to work for
these two boards.
We still have two omap3 boards booting in legacy mode in addition
to device tree based booting. All the other ten or so omap2+ SoCs
have been booting using device tree mode only for years now. This
has allowed us to get rid of quite a bit of arch/arm/mach-omap2
related platform init code in favor of dts and driver changes.
Pretty much the only remaining known users for omap3 legacy boot
board files are Kevin's and Russell's boot test systems, and N900
kernel tree maintained by Pali and Ivaylo. And all of them are
also supporting the device tree based booting. The legacy booting
mode has been kept around mostly to verify against regressions.
As there is still a slim chance of possible other uses of the
mainline kernel for these boards, let's just drop the board
files for v4.8, and let's not touch the related platform init
code until around v4.9 time if no issues are found. This makes
it trivial for us to add back the board files with a simple revert.

Merge "delete the RealView boardfiles" from Linus Walleij:
This deletes the realview boardfiles, consolidates a bit
around the Kconfig options and leaves the mach-realview
directory nice and tidy, with all boards migrated over to
Device Tree.

This reduces the Kconfig for the RealView by assuming we are
always booting from the device tree, and removing all the uses
of CONFIG_REALVIEW_DT and replacing with CONFIG_ARCH_REALVIEW.
Further:
- Drop REALVIEW_HIGH_PHYS_OFFSET: we don't use this with device
tree.
- Drop the REALVIEW_EB_ARM11MP_REVB option: we now handle this
by simply using another device tree.
- Drop the PB1176 secure flash option: this is defined in the
PB1176 device tree but marked as "disabled", so users who
want to use it can simply enable it in the device tree and
go hacking around.

property updates.
Due to assigning the 'replaced' value instead of or'ing it,
if drm_atomic_crtc_set_property() gets called multiple times,
the last call will define the color_mgmt_changed flag, so
a non-updating call to a property can reset the flag and
prevent actual hw state updates required by preceding
property updates.

DDB values for the pipes that are actually changing; the values for
other pipes remain 0. Thus a blind copy of the entire skl_wm_values
structure will clobber the values for unchanged pipes...we need to be
more selective and only copy over the values for the changing pipes.
This mistake was hidden until recently due to another bug that caused us
to erroneously re-calculate watermarks for all active pipes rather than
changing pipes. Only when that bug was fixed was the impact of this bug
discovered (e.g., modesets failing with "Requested display configuration
exceeds system watermark limitations" messages and leaving watermarks
non-functional, even ones initiated by intel_fbdev_restore_mode).
Changes since v1:
- Add a function for copying a pipe's wm values
(skl_copy_wm_for_pipe()) so we can reuse this later
Fixes: 734fa01f3a17 ("drm/i915/gen9: Calculate watermarks during atomic 'check' (v2)")
Fixes: 9b6130227495 ("drm/i915/gen9: Re-allocate DDB only for changed pipes")

Since the watermark calculations for Skylake are still broken, we're apt
to hitting underruns very easily under multi-monitor configurations.
While it would be lovely if this was fixed, it's not. Another problem
that's been coming from this however, is the mysterious issue of
underruns causing full system hangs. An easy way to reproduce this with
a skylake system:
- Get a laptop with a skylake GPU, and hook up two external monitors to
it
- Move the cursor from the built-in LCD to one of the external displays
as quickly as you can
- You'll get a few pipe underruns, and eventually the entire system will
just freeze.
After doing a lot of investigation and reading through the bspec, I
found the existence of the SAGV, which is responsible for adjusting the
system agent voltage and clock frequencies depending on how much power
we need. According to the bspec:
"The display engine access to system memory is blocked during the
adjustment time. SAGV defaults to enabled. Software must use the
GT-driver pcode mailbox to disable SAGV when the display engine is not
able to tolerate the blocking time."
The rest of the bspec goes on to explain that software can simply leave
the SAGV enabled, and disable it when we use interlaced pipes/have more
then one pipe active.
Sure enough, with this patchset the system hangs resulting from pipe
underruns on Skylake have completely vanished on my T460s. Additionally,
the bspec mentions turning off the SAGV with more then one pipe enabled
as a workaround for display underruns. While this patch doesn't entirely
fix that, it looks like it does improve the situation a little bit so
it's likely this is going to be required to make watermarks on Skylake
fully functional.
This will still need additional work in the future: we shouldn't be
enabling the SAGV if any of the currently enabled planes can't enable WM
levels that introduce latencies >= 30 µs.
Changes since v11:
- Add skl_can_enable_sagv()
- Make sure we don't enable SAGV when not all planes can enable
watermarks >= the SAGV engine block time. I was originally going to
save this for later, but I recently managed to run into a machine
that was having problems with a single pipe configuration + SAGV.
- Make comparisons to I915_SKL_SAGV_NOT_CONTROLLED explicit
- Change I915_SAGV_DYNAMIC_FREQ to I915_SAGV_ENABLE
- Move printks outside of mutexes
- Don't print error messages twice
Changes since v10:
- Apparently sandybridge_pcode_read actually writes values and reads
them back, despite it's misleading function name. This means we've
been doing this mostly wrong and have been writing garbage to the
SAGV control. Because of this, we no longer attempt to read the SAGV
status during initialization (since there are no helpers for this).
- mlankhorst noticed that this patch was breaking on some very early
pre-release Skylake machines, which apparently don't allow you to
disable the SAGV. To prevent machines from failing tests due to SAGV
errors, if the first time we try to control the SAGV results in the
mailbox indicating an invalid command, we just disable future attempts
to control the SAGV state by setting dev_priv->skl_sagv_status to
I915_SKL_SAGV_NOT_CONTROLLED and make a note of it in dmesg.
- Move mutex_unlock() a little higher in skl_enable_sagv(). This
doesn't actually fix anything, but lets us release the lock a little
sooner since we're finished with it.
Changes since v9:
- Only enable/disable sagv on Skylake
Changes since v8:
- Add intel_state->modeset guard to the conditional for
skl_enable_sagv()
Changes since v7:
- Remove GEN9_SAGV_LOW_FREQ, replace with GEN9_SAGV_IS_ENABLED (that's
all we use it for anyway)
- Use GEN9_SAGV_IS_ENABLED instead of 0x1 for clarification
- Fix a styling error that snuck past me
Changes since v6:
- Protect skl_enable_sagv() with intel_state->modeset conditional in
intel_atomic_commit_tail()
Changes since v5:
- Don't use is_power_of_2. Makes things confusing
- Don't use the old state to figure out whether or not to
enable/disable the sagv, use the new one
- Split the loop in skl_disable_sagv into it's own function
- Move skl_sagv_enable/disable() calls into intel_atomic_commit_tail()
Changes since v4:
- Use is_power_of_2 against active_crtcs to check whether we have > 1
pipe enabled
- Fix skl_sagv_get_hw_state(): (temp & 0x1) indicates disabled, 0x0
enabled
- Call skl_sagv_enable/disable() from pre/post-plane updates
Changes since v3:
- Use time_before() to compare timeout to jiffies
Changes since v2:
- Really apply minor style nitpicks to patch this time
Changes since v1:
- Added comments about this probably being one of the requirements to
fixing Skylake's watermark issues
- Minor style nitpicks from Matt Roper
- Disable these functions on Broxton, since it doesn't have an SAGV

In order to add proper support for the SAGV, we need to be able to know
what the cause of a failure to change the SAGV through the pcode mailbox
was. The reasoning for this is that some very early pre-release Skylake
machines don't actually allow you to control the SAGV on them, and
indicate an invalid mailbox command was sent.
This also might come in handy in the future for debugging.
Changes since v1:
- Add functions for interpreting gen6 mailbox error codes along with
gen7+ error codes, and actually interpret those codes properly
- Renamed patch to reflect new behavior

In the recent patch
bc3d674 drm/i915: Allow userspace to request no-error-capture upon ...
the final version moved the flags and the associated #defines around
so they were adjacent; unfortunately, they ended up between a comment
and the thing (hw_id) to which the comment applies :(
So this patch reshuffles the comment and subject back together.
Also, as we're touching 'hw_id', let's change it from just 'unsigned'
to a fully-specified 'unsigned int', because some code checking tools
(including checkpatch) object to plain 'unsigned'.

If userspace is asynchronously streaming into the batch or other
execobjects, we may not flush those writes along with a change in cache
domain (as there is no change). Therefore those writes may end up in
internal chipset buffers and not visible to the GPU upon execution. We
must issue a flush command or otherwise we encounter incoherency in the
batchbuffers and the GPU executing invalid commands (i.e. hanging) quite
regularly.
v2: Throw a paranoid wmb() into the general flush so that we remain
consistent with before.

It's possible to have a non-zero plane mask and still wind up with a
total data rate of zero. There are two cases where this can happen:
* planes are active (from the KMS point of view), but are
all fully clipped (positioned offscreen)
* the only active plane on a CRTC is the cursor (which is handled
independently and not counted into the general data rate computations
These are both valid display setups (although unusual), so we need to
drop the WARN().

intel_state->active_crtcs is usually only initialized when doing a
modeset. During our first atomic commit after boot, we're effectively
faking a modeset to sanitize the DDB/wm setup, so ensure that this field
gets initialized before use.

- Don't clobber active_crtcs if our first commit really is a modeset
(Maarten)
- Grab connection_mutex when faking a modeset during sanitization

For reasons that entirely elude me fb.h exposes all the structures,
even when it is not enabled. Except for special stuff like fb_defio.
Which means all the drivers which haven't yet switched over to the
defio support in the helpers and still roll their own, will fail
to compile when fbdev emulation is disabled. Protect just those
bits, as a gnarly reminder that conversion to the core defio helpers
would be good.
