OpRegion event on 965G requires legacy BLC event enabled in pipe stat. As LVDS
could be on either pipe now, we should enable BLC event on both pipe. If fail to
do so, we couldn't handle the brightness request triggered from graphics
opregion.

This was brought over from UMS, and used for a while until we decided
that drm_helper_resume_force_mode was easier and more reliable, since
it didn't require duplicating all the code deleted here. We just
forgot to delete all that junk for a while.

This one replaces original param for intel_ddc_get_modes() with
DRM connector and i2c bus adapter instead. With explicit params,
we won't require that a single driver structure must hold connector
and DDC bus reference, which ease the conversion to splitted encoder/
connector model.
It also clears up for some cases that we would steal other DDC bus
for mode probe, like VGA analog DDC probe for DVI-I. Also it fixed
a bug in old DVI-I probe handling, that failed to restore origin
analog GPIO port.

In load detection, connector's encoder assignment must be kept
consistent for proper mode setting, and this makes connector as
explicit parameter for load detect function to not require single
data structure to hold both encoder and connector reference, ease
the transition for splitted encoder/connector model.

detection reliable
The TV detection logic is not reliable on the Cantiga platform.
Sometimes the TV will be misdetected as the following two cases:
- TV is misdetected on some laptops. e.g. There is no TV connector
port or no TV is attached. But the TV is shown as connected.
- TV connector type is misdetected. e.g. the component TV is
attached, but the TV is shown as S-video type.
According to the hardware requirement, the TV sense state bits of TV DAC
register should be cleared to zero on Cantiga platfrom.

RADEON_CNTL_PAINT/BITBLT_MULTI.
* Don't leak memory if drm_buffer_copy_from_user() fails.
* Don't call drm_buffer_unprocessed() unless drm_buffer_alloc() and

In the original code we used "j" as an iterator but we used "i" as an
index.
- for (j = 0; j < i; j++)
- device_remove_file(&connector->kdev,
- &connector_attrs[i]);
Smatch complained about that because "i" was potentially passed the end of
the array. Which makes sense if we should be using "j" there.
I also thought that we should remove the files for &connector_attrs_opt1
but to do that I had to add separate iterators for &connector_attrs and
&connector_attrs_opt1.

Selecting the wrong or no CONFIG_AGP_* chipset can cause a NULL pointer
dereference when combined with CONFIG_DRM_RADEON_KMS and an old system
with a R100 AGP card (should effect other cards too). The agp field
will be set to NULL if no suitable AGP chipset driver is loaded,
drm_agp_acquire already preforms a suitable NULL check so it can be used
directly.

Commit b4fe945405e477cded91772b4fec854705443dd5 ("drm/radeon: Fix
memory allocation failures in the preKMS command stream checking.")
added a regression in that it completely tossed the get_unaligned()
done by r300_scratch() which we added in commit
958a6f8ccb1964adc3eec84cf401c5baeb4fbca0 ("drm: radeon: Fix unaligned
access in r300_scratch().").
Put it back.

When we call drm_vblank_off() at DPMS off time (to wake any clients so
they don't hang) we need to make sure interrupts are actually disabled.
If drm_vblank_off() gets called before the vblank usage timer expires,
it'll prevent the timer from disabling interrupts since it also clears
the vblank_enabled flag for the pipe.

My PIPE_CONTROL fix (just sent via Eric's tree) was buggy; I was
testing a whole set of patches together and missed a conversion to the
new HAS_PIPE_CONTROL macro, which will cause breakage on non-Ironlake
965 class chips. Fortunately, the fix is trivial and has been tested.
Be sure to use the HAS_PIPE_CONTROL macro in i915_get_gem_seqno, or
we'll end up reading the wrong graphics memory, likely causing hangs,
crashes, or worse.

Since 965, the hardware has supported the PIPE_CONTROL command, which
provides fine grained GPU cache flushing control. On recent chipsets,
this instruction is required for reliable interrupt and sequence number
reporting in the driver.
So add support for this instruction, including workarounds, on Ironlake
and Sandy Bridge hardware.

Current code is definitely crap: Largest pitch allowed spills into
the TILING_Y bit of the fence registers ... :(
I've rewritten the limits check under the assumption that 3rd gen hw
has a 3d pitch limit of 8kb (like 2nd gen). This is supported by an
otherwise totally misleading XXX comment.
This bug mostly resulted in tiling-corrupted pixmaps because the kernel
allowed too wide buffers to be tiled. Bug brought to the light by the
xf86-video-intel 2.11 release because that unconditionally enabled
tiling for pixmaps, relying on the kernel to check things. Tiling for
the framebuffer was not affected because the ddx does some additional
checks there ensure the buffer is within hw-limits.
v2: Instead of computing the value that would be written into the
hw fence registers and then checking the limits simply check whether
the stride is above the 8kb limit. To better document the hw, add
some WARN_ONs in i915_write_fence_reg like I've done for the i830
case (using the right limits).

we used to set the DIDL in the output device detected order.
But some BIOSes requires it to be initialized in the ACPI device order.
e.g. the value of the first field in DIDL stands for the first
ACPI video output device in ACPI namespace.
Now we initialize the DIDL using the device id, i.e. _ADR return value,
of each ACPI video device, if it is not 0.

IS_MOBILE() catches 85x, so we'd always try to use the 9xx FIFO sizing;
since there's an explicit 85x version, this seems wrong.
v2: Handle 830m correctly too.
