Try to decypher detection failures is a little tricker at the moment as
the only indicator of progress is when output_poll_execute() tells us
the result after the connector->detect() has run. This patch adds a
telltale to the start of each detect function so that we can track
progress and associate activity more clearly with each connector.

The recent addition of lockdep support to reservations and their subsequent
use by TTM showed up a number of potential problems with the way qxl was using
TTM objects.
a) it was allocating objects, and reserving them later without validating
underneath the reservation, which meant in extreme conditions the objects could
be evicted before the reservation ever used them.
b) it was reserving objects straight after allocating them, but with no
ability to back off should the reservations fail. It now allocates the necessary
objects then does a complete reservation pass on them to avoid deadlocks.
c) it had two lists per release tracking objects, unnecessary complicating
the reservation process.
This patch removes the dual object tracking, adds reservations ticket support
to the release and fence object handling. It then ports the internal fb
drawing code and the userspace facing ioctl to use the new interfaces properly,
along with cleanup up the error path handling in some codepaths.

In order to fix an issue with reservations we need to create the releases
as pre-pinned objects, this changes the placement interface and bo creation
interface to allow creating pinned objects to save nested reservations later.
This is just a stepping stone to main fix which follows to actually fix how
qxl deals with reservations.

Due to the nature of qxl hw we cannot queue operations while in an irq
context, so we queue these operations as best we can until atomic allocations
fail, and dequeue them later in a work queue.
Daniel looked over the locking on the list and agrees it should be sufficent.
The atomic allocs use no warn, as the last thing we want if we haven't memory
to allocate space for a printk in an irq context is more printks.

drm_gem_object_init() and drm_gem_private_object_init() do exactly the
same (except for shmem alloc) so make the first use the latter to reduce
code duplication.
Also drop the return code from drm_gem_private_object_init(). It seems
unlikely that we will extend it any time soon so no reason to keep it
around. This simplifies code paths in drivers, too.
Last but not least, fix gma500 to call drm_gem_object_release() before
freeing objects that were allocated via drm_gem_private_object_init().
That isn't actually necessary for now, but might be in the future.

drm/i915: fixup 12bpc hdmi dotclock handling
I've errornously claimed that we don't yet support the hdmi 1.4
dotclocks > 225 MHz on Haswell. But a bug report and a closer look at
the wrpll table showed that we've supported port clocks up to 300MHz.
With the new code to dynamically compute wrpll limits we should have
no issues going up to the full 340 MHz range of hdmi 1.4, so let's
just use that to fix this regression. That'll allow 4k over hdmi for
free!
v2: Drop the random hunk that somehow slipped in.
v3: Cantiga has the original HDMI dotclock limit of 165MHz. And also
patch up the mode filtering. To do so extract the dotclock limits into
a little helper function.
v4: Use 300MHz (from Bspec) instead of 340MHz (upper limit for hdmi
1.3), apparently hw is not required to be able to drive the highest
dotclocks. Suggested by Damien.

Noticed that my old Radeon 7500 hung after printing
drm: GPU not posted. posting now...
when it wasn't selected as the primary card the BIOS. Some digging
revealed that it was hanging in combios_parse_mmio_table() while
parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card,
it becomes obvious that there is no ASIC INIT 3 table in the BIOS.
The code is just processing random garbage. No surprise it hangs!
Why do I say that there is no ASIC INIT 3 table is the BIOS? This
table is found through the MISC INFO table. The MISC INFO table can
be found at offset 0x5e in the COMBIOS header. But the header is
smaller than that. The COMBIOS header starts at offset 0x126. The
standard PCI Data Structure (the bit that starts with 'PCIR') lives at
offset 0x180. That means that the COMBIOS header can not be larger
than 0x5a bytes and therefore cannot contain a MISC INFO table.
I looked at a dozen or so BIOS images, some my own, some downloaded from:
<http://www.techpowerup.com/vgabios/index.php?manufacturer=ATI&page=1>
It is fairly obvious that the size of the COMBIOS header can be found
at offset 0x6 of the header. Not sure if it is a 16-bit number or
just an 8-bit number, but that doesn't really matter since the tables
seems to be always smaller than 256 bytes.
So I think combios_get_table_offset() should check if the requested
table is present. This can be done by checking the offset against the
size of the header. See the diff below. The diff is against the WIP
OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this
point. But I don't think this bit of the code changed much since
then.

Atm the crtc helper implementation of set_config has really

drm/i915: force full modeset if the connector is in DPMS OFF mode

The history of this dpms forcing is pretty interesting. This patch

drm: Only set DPMS ON when actually configuring a mode

Author: Keith Packard <keithp@keithp.com>
Date: Fri Nov 26 10:45:58 2010 -0800
drm: Set connector DPMS status to ON in drm_crtc_helper_set_config
And if you'd dig around in the i915 driver code there's even more fun
around forcing dpms on and losing our heads and temper of the
resulting inconsistencies. Especially the DP re-training code had tons
of funny stuff in it.
v2: So v1 totally blew up on resume on my radeon system here. After
much head-scraching I've figured out that the radeon resume functions
resumes the console system _before_ it actually restores all the
modeset state. And resuming the console systems means that fbdev doeas
an immediate ->set_par call.
Now up to this patch that ->set_par did absolutely nothing: All the
old sw state from pre-suspend was still around (since the modeset
reset wasn't done yet), which means that the set_config calls done as
a result of the ->set_par where all treated as no-ops (despite that
the real hw state was obviously something completely different).
Since v1 of this patch just added a bunch of ->dpms calls if the crtc
was enabled, those set_config calls suddenly stopped being no-ops. But
because the hw state wasn't restored the ->dpms callbacks resulted in
decent amounts of hilarity and eventual full hangs.
Since I can't review all kms drivers for such tricky ordering
constraints v2 opts for a different approach and forces a full modeset
if the connector dpms state isnt' DPMS_ON. Since the ->dpms callbacks
implemented by the modeset helpers update the connector->dpms property
we have the same effect of ensuring that the pipe is ultimately turned
on, even if we just end up updating the fb. This is the same approac
we ended up using in the intel driver.
Note that besides i915.ko only all other drivers eventually call
drm_helper_connector_dpms with the exception of vmwgfx, which does not
support dmps at all.

Pull ACPI video support fixes from Rafael Wysocki:
"I'm sending a separate pull request for this as it may be somewhat
controversial. The breakage addressed here is not really new and the
fixes may not satisfy all users of the affected systems, but we've had
so much back and forth dance in this area over the last several weeks
that I think it's time to actually make some progress.
The source of the problem is that about a year ago we started to tell
BIOSes that we're compatible with Windows 8, which we really need to
do, because some systems shipping with Windows 8 are tested with it
and nothing else, so if we tell their BIOSes that we aren't compatible
with Windows 8, we expose our users to untested BIOS/AML code paths.
However, as it turns out, some Windows 8-specific AML code paths are
not tested either, because Windows 8 actually doesn't use the ACPI
methods containing them, so if we declare Windows 8 compatibility and
attempt to use those ACPI methods, things break. That occurs mostly
in the backlight support area where in particular the _BCM and _BQC
methods are plain unusable on some systems if the OS declares Windows
8 compatibility.
[ The additional twist is that they actually become usable if the OS
says it is not compatible with Windows 8, but that may cause
problems to show up elsewhere ]
Investigation carried out by Matthew Garrett indicates that what
Windows 8 does about backlight is to leave backlight control up to
individual graphics drivers. At least there's evidence that it does
that if the Intel graphics driver is used, so we've decided to follow
Windows 8 in that respect and allow i915 to control backlight (Daniel
likes that part).
The first commit from Aaron Lu makes ACPICA export the variable from
which we can infer whether or not the BIOS believes that we are
compatible with Windows 8.
The second commit from Matthew Garrett prepares the ACPI video driver
by making it initialize the ACPI backlight even if it is not going to
be used afterward (that is needed for backlight control to work on
Thinkpads).
The third commit implements the actual workaround making i915 take
over backlight control if the firmware thinks it's dealing with
Windows 8 and is based on the work of multiple developers, including
Matthew Garrett, Chun-Yi Lee, Seth Forshee, and Aaron Lu.
The final commit from Aaron Lu makes us follow Windows 8 by informing
the firmware through the _DOS method that it should not carry out
automatic brightness changes, so that brightness can be controlled by
GUI.
Hopefully, this approach will allow us to avoid using blacklists of
systems that should not declare Windows 8 compatibility just to avoid
backlight control problems in the future.

initialized (which isn't the case here) call it sanitze instead.
While at it also block out the rps disable introduced by the above
commit on ilk: We don't have any knowledge of ilk rps being broken in
similar ways. And the disable functions uses the default hw state
which is only read out when we're enabling rps. So essentially we've
been writing random grabage into that register.

In theory, the different register blocks were meant to be only ever
touched when holding either the struct_mutex, mode_config.lock or even a
specific localised lock. This does not seem to be the case, and the
hardware reacts extremely badly if we attempt to concurrently access two
registers within the same cacheline.
The HSD suggests that we only need to do this workaround for display
range registers. However, upon review we need to serialize the multiple
stages in our register write functions - if only for preemption
protection.
Irrespective of the hardware requirements, the current io functions are
a little too loose with respect to the combination of pre- and
post-condition testing that we do in conjunction with the actual io. As
a result, we may be pre-empted and generate both false-postive and
false-negative errors.
Note well that this is a "90%" solution, there remains a few direct
users of ioread/iowrite which will be fixed up in the next few patches.
Since they are more invasive and that this simple change will prevent
almost all lockups on Haswell, we kept this patch simple to facilitate
backporting to stable.

It was very similar to ironlake_irq_postinstall, so IMHO merging both
functions results in a code that is easier to maintain.
With this change, all the irq handler vfuncs between ironlake and
ivybridge are now unified.

The IVB funtions are exactly the same as the ILK ones, with the
exception of the bit register. So add IVB/HSW support to
ironlake_enable_vblank and ironlake_disable_vblank, then kill the
ivybridge functions.

And then rename it to ironlake_irq_handler. Also move
ilk_gt_irq_handler up to avoid forward declarations.
In the previous patches I did small modifications to both
ironlake_irq_handler an ivybridge_irq_handler so they became very
similar functions. Now it should be very easy to verify that all we
need to add ILK/SNB support is to call ilk_gt_irq_handler, call
ilk_display_irq_handler and avoid reading pm_iir on gen 5.
v2: - Rebase due to changes on the previous patches
- Move pm_iir to a tighter scope (Chris)
- Change some Gen checks for readability

We have this POSTING_READ inside ironlake_irq_handler. I suppose we
also want it on IVB because we want to stop the IRQ handler as soon as
possible at this point.

The ironlake_irq_handler and ivybridge_irq_handler functions do
basically the same thing, but they have different implementation
styles. With this patch we reorganize ironlake_irq_handler in a way
that makes it look very similar to ivybridge_irq_handler.
One of the advantages of this new function style is that we don't
write 0 to the IIR registers anymore.
