commit 260b3f1291a75a580d22ce8bfb1499c617272716 upstream.
While testing the mgag200 kms driver on the HP ProLiant Gen8, a
bug was seen. Once the bootloader would load the selected kernel,
the screen would go black. At first it was assumed that the
mgag200 kms driver was hanging. But after setting up the grub
serial output, it was seen that the driver was being loaded
properly. After trying serval monitors, one finaly displayed
the message "Frequency Out of Range". By comparing the kms pll
algorithm with the previous mgag200 xorg driver pll algorithm,
discrepencies were found. Once the kms pll algorithm was
modified, the expected pll values were produced. This fix was
tested on several monitors of varying native resolutions.

commit c19b3b0f6eed552952845e4ad908dba2113d67b4 upstream.
When KMS has parsed an EDID "detailed timing", it leaves the frame rate
zeroed. Consecutive (debug-) output of that mode thus yields 0 for
vsync. This simple fix also speeds up future invocations of
drm_mode_vrefresh().
While it is debatable whether this qualifies as a -stable fix I'd apply
it for consistency's sake; drm_helper_probe_single_connector_modes()
does the same thing already for all probed modes.

commit 16dad1d743d31a104a849c8944e6b9eb479f6cd7 upstream.
EDID spreads some values across multiple bytes; bit-fiddling is needed
to retrieve these. The current code to parse "detailed timings" has a
cut&paste error that results in a vsync offset of at most 15 lines
instead of 63.
See
http://en.wikipedia.org/wiki/EDID
and in the "EDID Detailed Timing Descriptor" see bytes 10+11 show why
that needs to be a left shift.

drm/i915: Fix blank panel at reopening lid
fixed a regression in 3.6-rc kernels for which we've never figured out
the exact root cause. But some further inspection of the backlight
code reveals that it's seriously lacking locking. And especially the
asle backlight update is know to get fired (through some smm magic)
when writing specific backlight control registers. So the possibility
of suffering from races is rather real.
Until those races are fixed I don't think it makes sense to try
further hacks. Which sucks a bit, but sometimes that's how it is :(

commit 15239099d7a7a9ecdc1ccb5b187ae4cda5488ff9 upstream.
We need it to restore the ilk rc6 context, since the gpu wait no
requires interrupts. But in general having interrupts around should
help in code sanity, since more and more stuff is interrupt driven.

drm/i915: Rearrange code to only have a single method for waiting upon the ring
Like in the driver load code we need to make sure that hotplug
interrupts don't cause havoc with our modeset state, hence block them
with the existing infrastructure. Again we ignore races where we might
loose hotplug interrupts ...
Note that the driver load part of the regression has already been

commit 52d7ecedac3f96fb562cb482c139015372728638 upstream.
Otherwise the new&shiny irq-driven gmbus and dp aux code won't work that
well. Noticed since the dp aux code doesn't have an automatic fallback
with a timeout (since the hw provides for that already).
v2: Simple move drm_irq_install before intel_modeset_gem_init, as
suggested by Ben Widawsky.
v3: Now that interrupts are enabled before all connectors are fully
set up, we might fall over serving a HPD interrupt while things are
still being set up. Instead of jumping through massive hoops and
complicating the code with a separate hpd irq enable step, simply
block out the hotplug work item from doing anything until things are
in place.
v4: Actually, we can enable hotplug processing only after the fbdev is
fully set up, since we call down into the fbdev from the hotplug work
functions. So stick the hpd enabling right next to the poll helper
initialization.
v5: We need to enable irqs before intel_modeset_init, since that
function sets up the outputs.
v6: Fixup cleanup sequence, too.

commit bc752862170c135d6c09fb22d79eeb451023568e upstream.
We trim the fb to fit the CRTC by computing the offset of that CRTC to
its nearest tile_row origin. This allows us to use framebuffers that are
larger than the CRTC limits without additional work.
However, we failed to compute the offset for a linear framebuffer
correctly as we treated its x-advance in whole tiles (instead of the
linear increment expected), leaving the CRTC misaligned with its
contents.

drm/i915: Fix blank panel at reopening lid
changed the register write sequence for restoring the backlight, which
helped prevent non-working backlights on some machines. Turns out that
the original sequence was the right thing to do for a different set of
machines. Worse, setting the backlight level _after_ enabling it seems
to reset it somehow. So we need to make that one conditional upon the
backlight having been reset to zero, and add the old one back.
Cargo-culting at it's best, but it seems to work.

commit 7083e05072b88d503d257b6f012ce56367f3ac97 upstream.
The RC6 VIDS has a linear ramp starting at 250mv, which means any values
below 250 are invalid. The old buggy macros tried to adjust for this to
be more flexible, but there is no need. As Dan pointed out the ENCODE
only ever has one value. The only invalid value for decode is an input
of 0 which means something is really wonky, and the cases where DECODE
are used either don't matter (debug values), or would be implicitly
correct (the check for less than 450).
This patch makes simpler, easier to read macros which are actually
correct. Maybe this patch can actually fix some bugs now.
Thanks to Dan for catching this. /me hides

The FDI link has supported link reversal to make the PCB layout

We're trying to take a bit more control over what the BIOS leaves in
various register and with the introduction of DDI, started to program
FDI_RX_CTL fully.
There's a fused bit to indicate DMI link reversal and FDI defaults to
mirroring that configuration. We have a bit to override that behaviour
that we need to preserve from the BIOS.

commit 9f23de52b64f7fb801fd76f3dd8651a0dc89187b upstream.
While looking at plymouth on udl I noticed that plymouth was trying
to use its fb plugin not its drm one, it was trying to drmOpen a driver called
usb not udl, noticed that we actually had out driver pointing at the wrong
device.

commit db3985e5ca8f50fc17606855ba394783d11683a5 upstream.
This reverts commit 6f33814bd4d9cfe76033a31b1c0c76c960cd8e4b.
The quirk cause a regression, and it looks like the original bug was
simply a lack of FIFO bandwidth on the i915G of the reporter. Which
should eventually be fixed as soon as we get around to implemented
DSPARB FIFO reassignment on gen 3.

commit d84f031bd230fdf9c3b7734940c859bf28b90219 upstream.
Support for real RGB332 is a rarity, most hardware only really support
C8. So use C8 instead of RGB332 when determining the format based on
depth/bpp.
This fixes 8bpp fbcon on i915, since i915 will only accept C8 and not
RGB332.

commit 196e077dc165a307efbd9e7569f81bbdbcf18f65 upstream.
If bit 0 of the features byte (0x18) is set to 0, then, according to
the EDID spec, "the display is non-continuous frequency (multi-mode)
and is only specified to accept the video timing formats that are
listed in Base EDID and certain Extension Blocks".
For more information, please see the EDID spec, check the notes of the
table that explains the "Feature Support" byte (18h) and also the
notes on the tables of the section that explains "Display Range Limits
& Additional Timing Description Definition (tag #FDh)".

commit bcb39af4486be07e896fc374a2336bad3104ae0a upstream.
Okay you don't really want to use udl devices as your console, but if
you are unlucky enough to do so, you run into a lot of schedule while atomic
due to printk being called from all sorts of funky places. So check if we
are in an atomic context, and queue the damage for later, the next printk
should cause it to appear. This isn't ideal, but it is simple, and seems to
work okay in my testing here.
(dirty area idea came from xenfb)
fixes a bunch of sleeping while atomic issues running fbcon on udl devices.

git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile into akpm
Pull tile bugfixes from Chris Metcalf:
"This includes a variety of minor bug fixes, mostly to do with testing
"make allyesconfig", "make allmodconfig", "make allnoconfig", inspired
to Tejun Heo's observation about Kconfig.freezer not being included.
The largest changes are just syntax changes removing the tile-specific
use of a macro named INT_MASK, which is way too commonly redefined
throughout driver code"
* 'stable' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile:
tile: tag some code with #ifdef CONFIG_COMPAT
tile: fix memcpy_*io functions for allnoconfig
tile: export a handful of symbols appropriately
drm: fix compile failure by including <linux/swiotlb.h>
tile: avoid defining INT_MASK macro in <arch/interrupts.h>
tile: provide "screen_info" when enabling VT
drivers/input/joystick/analog.c: enable precise timer
tile: include kernel/Kconfig.freezer in tile Kconfig
tile: remove an unused variable in copy_thread()

When ever parsing cmd buffer supplied by userspace we need to use
radeon_get_ib_value rather than directly accessing the ib as the user
cmd might not yet be copied into the ib thus the parser might read
value that does not correspond to what user is sending and possibly
allowing user to send malicious command undected.
