Just minor stuff really, on vlv dp fix and two patches to tune down some
opregion sanity check. Plus MAINTAINERS update for the new git repo, which
is the only reason I've really bothered with this pull request.
* tag 'drm-intel-fixes-2014-02-06' of ssh://git.freedesktop.org/git/drm-intel:
drm/i915: demote opregion excessive timeout WARN_ONCE to DRM_INFO_ONCE
drm: add DRM_INFO_ONCE() to print a one-time DRM_INFO() message
MAINTAINERS: Update drm/i915 git repo
drm/i915: vlv: fix DP PHY lockup due to invalid PP sequencer setup
|
|
The WARN_ONCE is a bit too verbose, make it a DRM_INFO_ONCE.
While at it, add a #define for MAX_DSLP and make the message a bit more
informative.
v2: use DRM_INFO_ONCE, add MAX_DSLP, pimp the message.

My 855gm doesn't register the intel backlight but it still ends up
calling the backlight code to enable/disable the backlight via the
LVDS code. This leads to some WARNs due to backlight.max being 0.
Let's have intel_panel_enable_backlight() and intel_panel_disable_backlight()
check whether there's a backlight present or not.
Also move the backlight.present check from asle_set_backlight() into
intel_panel_set_backlight() for some extra symmetry.

Linux 3.13-rc3
I need a backmerge for two reasons:
- For merging the ppgtt patches from Ben I need to pull in the bdw
support.
- We now have duplicated calls to intel_uncore_forcewake_reset in the
setup code to due 2 different patches merged into -next and 3.13.
The conflict is silen so I need the merge to be able to apply

To avoid build problems and breaking dependencies between ACPI header
files, <acpi/acpi.h> should not be included directly by code outside
of the ACPI core subsystem. However, that is possible if
<linux/acpi_io.h> is included, because that file contains
a direct inclusion of <acpi/acpi.h>.
For this reason, remove the direct <acpi/acpi.h> inclusion from
<linux/acpi_io.h>, move that file from include/linux/ to include/acpi/
and make <linux/acpi.h> include it for CONFIG_ACPI set along with the
other ACPI header files. Accordingly, Remove the inclusions of
<linux/acpi_io.h> from everywhere.
Of course, that causes the contents of the new <acpi/acpi_io.h> file
to be available for CONFIG_ACPI set only, so intel_opregion.o that
depends on it should also depend on CONFIG_ACPI (and it really should
not be compiled for CONFIG_ACPI unset anyway).

Merge the bdw changes into the backlight rework branch so that we can
adapt the new code for bdw, too. This is a bit a mess, but doing this
another way would have delayed the merging of the backlight

enable function.

v2: Don't enable the PWM too early for bdw (Jani).
v3: Create new bdw_ functions for setup and enable - the rules change

The spec says the default timeout should be 2ms, but on my machine
this doesn't seem to be enough. Sometimes it works, sometimes I get
these messages when booting:
- SWSCI request timed out
- SWSCI request already in progress
And my guess is that the "already in progress" message is because the
first one is still happening.
I did some experiments on my machine (that has CONFIG_HZ=1000) and the
wait_for function usually takes 4-6 jiffies to finish, but I've seen
up to 9. So increase the timeout to 50ms. We only expect to wait for
the actual amount of time the operation takes, so even a huge timeout
shouldn't delay us more than what the hardware actually requires.

But I still see the "non asle set request??" message on my machine :(

ACPI has _BCM and _BQC methods to set and query the backlight
brightness, respectively. The ACPI opregion has variables BCLP and CBLV
to hold the requested and current backlight brightness, respectively.
The BCLP variable has range 0..255 while the others have range
0..100. This means the _BCM method has to scale the brightness for BCLP,
and the gfx driver has to scale the requested value back for CBLV. If
the _BQC method uses the CBLV variable (apparently some implementations
do, some don't) for current backlight level reporting, there's room for
rounding errors.
Use DIV_ROUND_UP for scaling back to CBLV to get back to the same values
that were passed to _BCM, presuming the _BCM simply uses bclp = (in *
255) / 100 for scaling to BCLP.

The bios interface seems messy, and it's hard to tell what the bios
really wants. At first, only add support for DDI based machines (hsw+),
and see how it turns out.
The spec says to notify prior to power down and after power up. It is
unclear whether it makes a difference.
v2:
- squash notification function and callers patches together (Daniel)
- move callers to haswell_crtc_{enable,disable} (Daniel)
- rename notification function (Chris)
v3:
- separate notification function and callers again, as it's not clear
whether the display power state notification is the right thing to do
after all

Stop calling intel_opregion_enable_asle() and consequently
intel_enable_asle() on opregion init. It should not be necessary for
these reasons:
1) On PCH split platforms, it only enables GSE interrupt, which is
enabled in irq postinstall anyway. Moreover, the irq enable uses the
wrong bit on IVB+.
2) On gen 2, it would enable a reserved pipestat bit. If there were gen
2 systems with opregion asle support, that is. And the gen 2 irq
handler won't handle it anyway.
3) On gen 3-4, the irq postinstall will call
intel_opregion_enable_asle() to enable the pipestat.
In short, move the asle irq/pipestat enable responsibility to irq
postinstall, which already happens to be in place.
This should not cause any functional changes, but only do the one line
change here for easier bisectability, just in case, and leave all the
cleanups this allows to followup patches.

combined pte writing, ilk rc6 support,
- nouveau: major driver rework into a hw core driver, makes features
like SLI a lot saner to implement,
- psb: add eDP/DP support for Cedarview
- radeon: 2 layer page tables, async VM pte updates, better PLL
selection for > 2 screens, better ACPI interactions
The rest is general grab bag of fixes.
So why part 1? well I have the exynos pull req which came in a bit
late but was waiting for me to do something they shouldn't have and it
looks fairly safe, and David Howells has some more header cleanups
he'd like me to pull, that seem like a good idea, but I'd like to get
this merge out of the way so -next dosen't get blocked."
Tons of conflicts mostly due to silly include line changes, but mostly
mindless. A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

Make it easier to track backlight set requests coming through ASLE instead
of the driver's own backlight sysfs interface. We've had enough of
backlight issues to warrant some extra debug logs in the area.

This is rather a hack to fix brightness hotkeys on a Clevo laptop. CADL is not
used anywhere in the driver code at the moment, but it could be used in BIOS as
is the case with the Clevo laptop.
The Clevo B7130 requires the CADL field to contain at least the ID of
the LCD device. If this field is empty, the ACPI methods that are called
on pressing brightness / display switching hotkeys will not trigger a
notification. As a result, it appears as no hotkey has been pressed.

Almost all of the errors related __iomem problems.
Most of the changes here are trivial, however there is plenty of chance
for yank/paste errors.

opregion-based platforms will send ACPI video event 0x80 for a range of
notification types for legacy compatibility. This is interpreted as a
display switch event, which may not be appropriate in the circumstances.
When we receive such an event we should make sure that the platform is
genuinely requesting a display switch before passing that event through
to userspace.

The opregion is a shared memory region between ACPI and the graphics
driver. As the ACPI mapping has been changed to cachable in commit
6d5bbf00d251cc73223a71422d69e069dc2e0b8d, mapping the intel opregion
non-cachable now fails. As no bus-master hardware is involved in the
opregion, cachable map should do no harm.
Tested on a Fujitsu Lifebook P8010.

Admittedly, trusting ACPI or the BIOS at all to be correct is littered
with numerous examples where it is wrong. Maybe, just maybe, we will
have better luck using the ACPI OpRegion lid status...
