Some machines suffer from non-functional backlight controls if
BLM_PCH_PWM_ENABLE is set, so provide a quirk to avoid doing so.
Apply this quirk to Dell XPS 13 models.

commit 42a21826dc54583cdb79cc8477732e911ac9c376 upstream.
The ProcessAuxChannel table on some rv635 boards assumes
the divmul members are initialized to 0 otherwise we get
an invalid fb offset since it has a bad mask set when
setting the fb base. While here initialize all the
atom interpretor elements to 0.

commit cef1d00cd56f600121ad121875655ad410a001b8 upstream.
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.
For what it is worth:

commit 53d3b4d7778daf15900867336c85d3f8dd70600c

drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC
Egbert Eich fixed a long-standing bug where we simply used a
non-working i2c controller to read the EDID for SDVO-LVDS panels.
Unfortunately some machines seem to not be able to cope with the mode
provided in the EDID. Specifically they seem to not be able to cope
with a 4x pixel mutliplier instead of a 2x one, which seems to have
been worked around by slightly changing the panels native mode in the
VBT so that the dotclock is just barely above 50MHz.
Since it took forever to notice the breakage it's fairly safe to
assume that at least for SDVO-LVDS panels the VBT contains fairly sane
data. So just switch around the order and use VBT modes first.
v2: Also add EDID modes just in case, and spell Egbert correctly.
v3: Elaborate a bit more about what's going on on Chris' machine.

a memory leak where the framebuffer was released but not unpinned

commit cbbd379aa43890f36da934f5af619d2fb8ec3d87 upstream.
By having a higher max resolution we can now set up a virtual
framebuffer that spans several monitors. 4096 should be ok since we're
gen 3 or higher and should be enough for most dual head setups.

commit 45a211d75137b1ac869a8a758a6667f15827a115 upstream.
Last year, a patch was made for the "HP t5740e Thin Client" (see
http://lists.freedesktop.org/archives/dri-devel/2012-May/023245.html).
This device reports an lvds panel, but does not really have one.
The predecessor of this device is the "hp t5740", which also does not have
an lvds panel. This patch will add the same quirk for this device.

commit 53d3b4d7778daf15900867336c85d3f8dd70600c upstream.
In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used
for DDC. Thus the code will always have to rely on a LVDS panel
mode supplied by VBT.
In most cases this succeeds, so this didn't get detected for quite
a while.

commit b7ea85a4fed37835eec78a7be3039c8dc22b8178 upstream.
When GPU acceleration is disabled, drm_vblank_cleanup() will free the
vblank-related data, such as vblank_refcount, vblank_inmodeset, etc.
But we found that drm_vblank_post_modeset() may be called after the
cleanup, which use vblank_refcount and vblank_inmodeset. And this will
cause a kernel panic.
Fix this by return immediately if dev->num_crtcs is zero. This is the
same thing that drm_vblank_pre_modeset() does.

commit e49f3959a96dc279860af7e86e6dbcfda50580a5 upstream.
The current radeon driver initialization routines, when using KMS, are written
so that the IRQ installation routine is called before initializing the WB buffer
and the CP rings. With some ASICs, though, the IRQ routine tries to access the
GFX_INDEX ring causing a call to RREG32 with the value of -1 in
radeon_fence_read. This, in turn causes the system to completely hang with some
cards, requiring a hard reset.
A call stack that can cause such a hang looks like this (using rv515 ASIC for the
example here):
* rv515_init (rv515.c)
* radeon_irq_kms_init (radeon_irq_kms.c)
* drm_irq_install (drm_irq.c)
* radeon_driver_irq_preinstall_kms (radeon_irq_kms.c)
* rs600_irq_process (rs600.c)
* radeon_fence_process - due to SW interrupt (radeon_fence.c)
* radeon_fence_read (radeon_fence.c)
* hang due to RREG32(-1)
The patch moves the IRQ installation to the card startup routine, after the ring
has been initialized, but before the IRQ has been set. This fixes the issue, but
requires a check to see if the IRQ is already installed, as is the case in the
system resume codepath.
I have tested the patch on three machines using the rv515, the rv770 and the
evergreen ASIC. They worked without issues.
This seems to be a known issue and has been reported on several bug tracking
sites by various distributions (see links below). Most of reports recommend
booting the system with KMS disabled and then enabling KMS by reloading the
radeon module. For some reason, this was indeed a usable workaround, however,
UMS is now deprecated and disabled by default.

commit 09fb8bd1a63b0f9f15e655c4fe8d047e5d2bf67a upstream.
Newer asics have variable numbers of crtcs. Use that
rather than the asic family to determine which crtcs
to check. This avoids checking non-existent crtcs or

commit 054430e773c9a1e26f38e30156eff02dedfffc17 upstream.
Okay so Alan's patch handled the case where there was no registered fbcon,
however the other path entered in set_con2fb_map pit.
In there we called fbcon_takeover, but we also took the console lock in a couple
of places. So push the console lock out to the callers of set_con2fb_map,
this means fbmem and switcheroo needed to take the lock around the fb notifier
entry points that lead to this.
This should fix the efifb regression seen by Maarten.

commit 4a35f83b2b7c6aae3fc0d1c4554fdc99dc33ad07 upstream.
Restore crtc->fb to the old framebuffer if queue_flip fails.
While at it, kill the pointless intel_fb temp variable.
v2: Update crtc->fb before queue_flip and restore it back
after a failure.
Backported for 3.4-stable. Adjusted context only.

commit d627b62ff8d4d36761adbcd90ff143d79c94ab22 upstream.
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.

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.

The Intel PRM says the M1 and M2 divisors must be in the range of 10-20 and 5-9.
Since we do all calculations based on them being register values (which are
subtracted by 2) we need to specify them accordingly.

If encoder is switched off by BIOS, but the panel fitter is left on,
we never try to turn off the panel fitter and leave it still attached
to the pipe - which can cause blurry output elsewhere.

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.
