same command.
Until now the software command checker assumed that commands could
read or write at most a single register per packet. This is not
necessarily the case, MI_LOAD_REGISTER_IMM expects a variable-length
list of offset/value pairs and writes them in sequence. The previous
code would only check whether the first entry was valid, effectively
allowing userspace to write unrestricted registers of the MMIO space
by sending a multi-register write with a legal first register, with
potential security implications on Gen6 and 7 hardware.
Fix it by extending the drm_i915_cmd_descriptor table to represent
multi-register access and making validate_cmd() iterate for all
register offsets present in the command packet.

Switch from using 31 PFI credits to 63 PFI credits when cdclk>=czclk on
CHV. The spec lists both 31 and 63 as "suggested" values, but based on
feedback from hardware folks we should actually be using 63. Originally
I picked the 31 basically by flipping a coin.

This patch fixes the resume from suspend-to-ram on the IBM X30
laptop. The problem is caused by the Bios missing to re-initialize
the iVCH registers, especially the PLL registers.
This patch records the iVCH registers during initialization, and
re-installs this register set when resuming.

Currently we're forgetting to double the port clock when using double
clocked modes with 12bpc on HDMI. We're only accounting for the 1.5x
factor due to the 12bpc. So further double the 1.5x port clock when we
have a double clocked mode.
Unfortunately I don't have any displays that support both 12bpc and
double clocked modes, so I was unable to test this.

Check that the DIP is enabled on the right port on IBX and VLV/CHV as
we're doing on g4x, and also check for all the infoframe enable bits on
all platforms.
Eventually we should track each infoframe type independently, and also
their contents. This is a small step in that direction as .infoframe_enabled()
return value could be easily turned into a bitmask.

Currently we just disable the GCP infoframe when turning off the port.
That means if the same transcoder is used on a DP port next, we might
end up pushing infoframes over DP, which isn't intended. Just disable
all the infoframes when turning off the port.
Also protect against two ports stomping on each other on g4x due to
the single video DIP instance. Now only the first port to enable
gets to send infoframes.

Follow the procedure listed in Bspec to toggle the port enable bit off
and on when enabling HDMI with 12bpc and pixel repeat on IBX. The old
code didn't actually enable the port before "toggling" the bit back off,
so the whole workaround was essentially a nop.
Also take the opportunity to clarify the code by splitting the gmch
platforms to a separate (much more straightforward) function.

When the video timings are suitably aligned so that all different
periods start at phase 0 (ie. none of the periods start mid-pixel)
we can inform the sink about this. Supposedly the sink can then
optimize certain things. Obviously this is only relevant when
outputting >8bpc data since otherwise there are no mid-pixel phases.

GCP infoframes are required to inform the HDMI sink about the color
depth.
Send the GCP infoframe whenever the sink supports any deep color modes
since such sinks must anyway be capable of receiving them. For sinks
that don't support deep color let's skip the GCP in case it might
confuse the sink, although HDMI 1.4 spec does say all sinks must be
capable of reciving them. In theory we could skip the GCP infoframe
for deep color sinks in 8bpc mode as well since sinks must fall back to
8bpc whenever GCP isn't received for some time.
BSpec says we should disable GCP after disabling the port, so do that as
well.

According to bspec the DDI PHY vswing scale value is "don't care" in
case the scale enable bit [27] is clear. But this doesn't seem to be
correct. The scale value seems to also matter if the scale mode bit
[26] is set. So both bit 26 and 27 depend on the value. Setting the
scale value to 0 while either bit is set results in a failed modeset on
HDMI (sink reports no signal).
After reset the scale value is 0x98, but according to the spec we have
to program it to 0x9a. So for consistency program it always to 0x9a
regardless of the scale enable bit.

DPLL0 is off then.
We still have a separate warn at boot if cdclk is disabled (because we

far as I know) where we boot with display not initialized.

Also with IPS enabled the actual pixel rate mustn't exceed 95% of cdclk,
so take that into account when computing the max pixel rate.

Bspec says we shouldn't enable IPS on BDW when the pipe pixel rate
exceeds 95% of the core display clock. Apparently this can cause
underruns.
There's no similar restriction listed for HSW, so leave that one alone
for now.

Keep the cdclk maximum supported frequency around in dev_priv so that we
can verify certain things against it before actually changing the cdclk
frequency.
For now only VLV/CHV have support changing cdclk frequency, so other
plarforms get to assume cdclk is fixed.

The hotplug status is cached in hp_control, and will be passed on to
bottom halves through intel_hpd_irq_handler(), so we can clear the
sticky bits earlier.
While at it, drop the redundant logging of the hotplug status, which
will also be logged by pch_get_hpd_pins().

information about which hpd pins triggered, and if they were long
pulses. The platform agnostic parts do further processing, such as
interrupt storm mitigation and scheduling bottom halves.

Implement cdclk extraction for g33, 965gm and g4x platforms. The details
came from configdb. Sadly there isn't anything there for other gen3/gen4
chipsets.
So far I've tested this on one ELK where it gave me a HPLL VCO of 5333
MHz and cdclk of 444 MHz which seems perfectly sane for this machine.

It seems 852GM/GMV uses a different HPLLCC encoding than the other
85x platforms. For 852GM/GMV cdclk is always 133MHz. Try to detect that
using the PCI revision (sinc the device ID seems useless for that). I'm
not at all sure this is a good idea, but according to the specs it
should work.

Actually read the HPLLCC register insted of assuming it's 0. Fix the
HPLLCC bit definitions and all the missing ones from the 852GME spec.
852GME, 854 and 855 all seem to match the same HPLLC encoding even
though only some of the values are valid is some of the platforms.

Printing it for PPGTT VMAs only adds noise since we have defined
view types are only applicable for GGTT.

The orignal code started by storing the actual central frequency (in Hz,
using a uint64_t) in a uint32_t which codes for the register value. That
can't be right.
