This patch reads the memory latency values for all the 8 levels for
SKL. These values are needed for the Watermark computation.
v2: Incorporated the review comments from Damien on register
indentation.
v3: Updated the code to use the sandybridge_pcode_read for reading
memory latencies for GEN9.
v4: Don't put gen 9 in the middle of an ordered list of ifs
(Damien)
v5: take the rps.hw_lock around sandybridge_pcode_read() (Damien)
v6: Use gen >= 9 in the pcode_read() function for data1.
Move the defines near the gen6 ones and prefix them with PCODE.
Remove unused timeout define (the pcode_read() code has a larger
timeout already).

Current chv spec teels we can only use either 16 or 32 bits as precision.
Although in the past VLV went from 16/32 to 32/64 and spec might not be updated,
these precision values brings stability and fixes some issues Wayne was facing.

Avoid to expose RC6 and RC6pp to the platforms that doesn't support it.
So powertop can be changed to show RC6p and RC6pp only on the platforms
they are available.
v2: Simplify by merging RC6p and RC6pp groups and respect the spec that
mentions deep and deepest RC6 on SNB and IVB although they keep disabled
by default.
v3: Remove unecessary space.
v4: RC6p and RC6pp is only for SNB and IVB; unify debug msg and use
has_rc6p() on sanitize options instead of is gen 6 and ivb.
v5: yet another fix on has_rc6p macro. final is_gen6 or is_ivb! To make sure
we are excluding hsw and baytrail.

Double negations just parse harder. Also this allows us to ditch some
init code since clearing to 0 dtrt. Also ditch the assignment in
intel_pm_setup, that's not redundant since we do the assignement now
while setting up interrupts.
While at it do engage in a bit of OCD and wrap up the few lines of
setup/teardown code into little helper functions: intel_irq_fini for
cleanup and intel_irq_init_hw for hw setup.
v2: Use _install/_uninstall for the new wrapper function names as
Paulo suggested.

The sw cache clean on BDW is a tempoorary workaround because we cannot
set cache clean on blt ring with risk of hungs. So we are doing the cache clean on sw.
However we are doing much more than needed. Not only when using blt ring.
So, with this extra w/a we minimize the ammount of cache cleans and call it only
on same cases that it was being called on gen7.
The traditional FBC Cache clean happens over LRI on BLT ring when there is a
frontbuffer touch happening. frontbuffer tracking set fbc_dirty variable
to let BLT flush that it must clean FBC cache.
fbc.need_sw_cache_clean works in the opposite information direction
of ring->fbc_dirty telling software on frontbuffer tracking to perform
the cache clean on sw side.
v2: Clean it a little bit and fully check for Broadwell instead of gen8.
v3: Rebase after frontbuffer organization.
v4: Wiggle confused me. So fixing v3!

Currently, calling intel_fbc_enabled() will trigger a register read.
And we call it a lot of times, even when FBC is disabled, so saving a
few cycles would be a good thing.
Another reason for this patch is because we currently call
intel_fbc_enabled() while the HW is runtime suspended, so the read
makes no sense and triggers a WARN. This happens even if FBC is
disabled by default. Of course one could argue that we just shouldn't
be calling intel_fbc_enabled() while the driver is runtime suspended,
and I agree that's a good argument, but I still think that the reason
explained in the first paragraph already justifies the patch.
This problem can easily be reproduced with many subtests of
igt/pm_rpm, and it is a regression introduced by:

830 is very unhappy of the watermark value is too low (indicating a very
high watermark in fact, ie. memory fetch will occur with an almost full
FIFO). Limit the watermark value to at least 8 cache lines.
That also matches the burst size we use on most platforms. BSpec seems
to indicate we should limit the watermark to 'burst size + 1'. But on
gen4 we already use a hardcoded 8 as the watermark value (as the spec
says we should), so just use 8 as the limit on gen2/3 as well.

My 830 is unhappy with trickle feed enabled. The symptom is that
the image on the screen shifts a bit to right occasionally.
The BIOS initially disables trickle feed, but it gets reset during
suspend, so we need to re-disable it ourselves. Juse disable it
always.
Also disable it for all other gen2/3 platforms since we disable it
for all more recent platforms as well (until HSW that is). At least
my 855 doesn't seem to mind us doing this. I don't have gen3
hardware to test that.

BDW supports GT C0 residency reporting in constant time unit. Driver
calculates GT utilization based on C0 residency and adjusts RP
frequency up/down accordingly. For offscreen workload specificly,
set frequency to RP0.
Offscreen task is not restricted by frame rate, it can be
executed as soon as possible. Transcoding and serilized workload
between CPU and GPU both need high GT performance, RP0 is a good
option in this case. RC6 will kick in to compensate power
consumption when GT is not active.

For BDW workarounds are currently initialized in init_clock_gating() but
they are lost during reset, suspend/resume etc; this patch moves the WAs
that are part of register state context to render ring init fn otherwise
default context ends up with incorrect values as they don't get initialized
until init_clock_gating fn.
v2: Add workarounds to golden render state
This method has its own issues, first of all this is different for
each gen and it is generated using a tool so adding new workaround
and mainitaining them across gens is not a straightforward process.
v3: Use LRIs to emit these workarounds (Ville)

According to spec FBC on BDW and HSW are identical without any gaps.
So let's copy the nuke and let FBC really start compressing stuff.
Without this patch we can verify with false color that nothing is being
compressed. With the nuke in place and false color it is possible
to see false color debugs.
Unfortunatelly on some rings like BCS on BDW we have to avoid Bits 22:18 on
LRIs due to a high risk of hung. So, when using Blt ring for frontbuffer rend
cache would never been cleaned and FBC would stop compressing buffer.
One alternative is to cache clean on software frontbuffer tracking.
v2: Fix rebase conflict.
v3: Do not clean cache on BCS ring. Instead use sw frontbuffer tracking.

"So I heard that proper pull requests have a revert on top ;-) So here
we go with my usual mid-merge-window pile of fixes.
[ Ed. This revert thing had better not become the "in" thing ]
Big fix is the duct-tape for ring init on g4x platforms, we seem to
have found the magic again to make those machines as happy as before
(not perfect though unfortunately, but that was never the case).
Otherwise fixes all over:
- tune down some overzealous debug output
- VDD power sequencing fix after resume
- bunch of dsi fixes for baytrail among them hw state checker
de-noising
- bunch of error state capture fixes for bdw
- misc tiny fixes/workarounds for various platforms
Last minute rebase was to kick out two patches that shouldn't have
been in here - they're for the state checker, so 0 functional code
affected.
Jani's back from vacation, so he'll take over -fixes from here"

Program DDL register as part of sprite watermark programming for CHV and VLV.
v2: Rename DRAIN_LATENCY_MAX by DRAIN_LATENCY_MASK
v3: Addressed review comments by Ville
- Changed Sprite DDL definitions to more generic to avoid multiple if-else
- Changed bit masking to customary form
- Changed to bitwise shorthand operator for sprite_dl assignment

Modify drain latency computation to use it for any plane. Same function can be
used for primary, cursor and sprite planes.
v2: Adressed review comments by Imre and Ville.
- Moved clock round up in separate patch
- Added WARN check for clock and pixel size
- Simplified bit masking
- Use cursor_base instead of reg read
v3: Changed to bitwise shorthand operator for plane_dl assignment.

Replace the semi-funky cmnlane assert/deassert macros with something a
bit more conventional. Also protect the macro arguments properly (also
for PHY_POWERGOOD()).

It looks like frobbing the cmnreset line on pne PHY disturbs the other
PHY on chv. The result is a black screen. On HDMI it's just a flash of
black, but DP usually falls over and can't get back up.
As a workaround set up the power domains so that both common lane
wells power up and down together. I also tried leaving the cmnreset
deasserted even the if the power well goes down but that didn't seem
acceptable to the PHY.

CHV has a third pipe so we need to compute the watermarks for its
planes. Add cherryview_update_wm() to do just that.

Instead of looping through all CRTCs, update DDL for current CRTC for which
watermark is being updated.
CHV is confirmed to have precision of 32/64 which is same as VLV.

The VLV/CHV DDL registers are uniform, and neatly enough the register
offsets are sane so we can easily unify them to a single set of defines
and just pass the pipe as the parameter to compute the register offset.
Note that we now fill out the drain latency for pipe C on CHV which we
didn't do before. The rest of the pipe C watermarks are still untouched
but that will be remedied later by adding a proper cherryview_update_wm()
function.
v2: Add a note about CHV pipe C changes (Paulo)

Add defines for all the watermark registers on modernish gmch platforms.
VLV has increased the number of bits available for certain watermaks so
expand the masks appropriately. Also vlv and chv have added some extra
FW registers.
Not sure what happened on chv because a new register called FW9 is now
at the offset where FW7 was on vlv, while FW7 and FW8 (another new
register) have been moved off somewhere else. Oh well, well just need
two defines for FW7 then.
