Subject: drm/i915/cnl: Introduce initial Cannonlake Workarounds.

Let's inherit workarounds from previous platforms that
according to wa_database and BSpec are still valid for
Cannonlake.

v2: Add missed workarounds.
v3: Rebase
v4: Remove bad chunk that was added to rc6 disable. (Ander)
    Also remove A0 W/a that are not needed anymore.
v5: Rebase on top of CFL.
v6: Remove empty gen9_init_perctx_bb and gen9_init_indirectctx_bb
    since they don't carry any gen10 related W/a. (by Oscar).
    Also Remove A0 exclusive workaround.
v7: Remove more A0 exclusive workarounds. As pointed out by Oscar
    many workarounds were changed to be A0 only so let's remove
    them.

Subject: drm/i915/cnl: Apply large line width optimization

This bit enables hardware that will change the approximation used for distances
calculations for AA wide lines so that they are rendered more accurately.

The default value for this bit leaves the legacy behavior. There is no good
reason to not enable the new approximation except if comparing to previous GEN
rendered images.

v2: Rebase
v3: Fix author.
    Rebased by Rodrigo who also added  a comment as suggested by Oscar.
    Since it is surrounded by Workarounds let's just add a comment to
    make clear it is not an Wa.

Subject: drm/i915: Boost GPU clocks if we miss the pageflip's vblank

If we miss the current vblank because the gpu was busy, that may cause a
jitter as the frame rate temporarily drops. We try to limit the impact
of this by then boosting the GPU clock to deliver the frame as quickly
as possible. Originally done in commit 6ad790c0f5ac ("drm/i915: Boost GPU
frequency if we detect outstanding pageflips") but was never forward
ported to atomic and finally dropped in commit fd3a40242e87 ("drm/i915:
Rip out legacy page_flip completion/irq handling").

One of the most typical use-cases for this is a mostly idle desktop.
Rendering one frame of the desktop's frontbuffer can easily be
accomplished by the GPU running at low frequency, but often exceeds
the time budget of the desktop compositor. The result is that animations
such as opening the menu, doing a fullscreen switch, or even just trying
to move a window around are slow and jerky. We need to respond within a
frame to give the best impression of a smooth UX, as a compromise we
instead respond if that first frame misses its goal. The result should
be a near-imperceivable initial delay and a smooth animation even
starting from idle. The cost, as ever, is that we spend more power than
is strictly necessary as we overestimate the required GPU frequency and
then try to ramp down.

This of course is reactionary, too little, too late; nevertheless it is
surprisingly effective.

No functional changes.

Our code was only a bit messy with mixed style there so
let's clean up a bit using the short codenames for the platforms.

Subject: drm/i915/cnp: Wa 1181: Fix Backlight issue

This workaround fixes a CNL PCH bug when changing
backlight from a lower frequency to a higher frequency.

During random reboot cycles, display backlight seems to
be off/ dim for 2-3 mins.

The only functional change on this patch is to
set bit 13 of 0xC2020 for CNL PCH.

The rest of patch is organizing identation around
those bits definitions and re-organizing CFL workarounds.

v2: Only add the bit that matters without touching others
    around (Jani).
    Rebase on top of clock gating functions rename.

Subject: drm/i915: Display WA #1133 WaFbcSkipSegments:cnl, glk

Skip compressing 1 segment at the end of the frame,
avoid a pixel count mismatch nuke event when last active
pixel and dummy pixel has same color for Odd Plane
Width / Height.

For both platforms Gemini Lake and Cannon Lake.

v2: Use function-like macro and also use mask to clean
    to make sure bit 11 is 0. (Suggested by Paulo).
v3: Add Display WA notation and also apply for GLK.
    Both Forgotten on v2.
    Using "GLK_" prefix since GLK came before CNL.
v4: Forgot to "|=" when moving directly macro to masked
    val. (Noticed by Paulo.)
v5: Rebased on top of 0a46ddd57c9e ("drm/i915/cnp: Wa 1181:
    Fix Backlight issue")

Subject: drm/i915/skl+: Optimize WM calculation

Plane configuration parameters doesn't change for each WM-level
calculation. Currently we compute same parameters 8 times for each
wm-level.
This patch optimizes it by calculating these parameters in beginning
& reuse during each level-wm calculation.

Changes since V1:
 - rebase on top of Rodrigo's series for CNL

Subject: drm/i915/gen10: Calculate and enable transition WM

GEN > 9 require transition WM to be programmed if IPC is enabled.
This patch calculates & enable transition WM for supported platforms.
If transition WM is enabled, Plane read requests are sent at high
priority until filling above the transition watermark, then the
requests are sent at lower priority until dropping below the level-0 WM.
The lower priority requests allow other memory clients to have better
memory access.

transition minimum is the minimum amount needed for trans_wm to work to
ensure  the demote does not happen before enough data has been read to
meet the level 0 watermark requirements.

transition amount is configurable value. Higher values will
tend to cause longer periods of high priority reads followed by longer
periods of lower priority reads. Tuning to lower values will tend to
cause shorter periods of high and lower priority reads.

Keeping transition amount to 10 in this patch, as suggested by HW team.

Changes since V1:
 - Address review comments from Maarten

Subject: drm/i915/glk: IPC linetime watermark workaround for GLK

IF IPC is enabled LINETIME_WM value should be half of calculated value
 line time = ROUNDDOWN(1/2 * Calculated Line Time)

Earlier code was rounding-up the value, But updated Bspec says we should
take the ROUNDDOWN. This patch corrects that as well.

Subject: drm/i915/bxt+: Enable IPC support

This patch adds IPC support. This patch also enables IPC in all supported
platforms based on has_ipc flag.
IPC (Isochronous Priority Control) is the hardware feature, which
dynamically controls the memory read priority of Display.

When IPC is enabled, plane read requests are sent at high priority until
filling above the transition watermark, then the requests are sent at
lower priority until dropping below the level 0 watermark.
The lower priority requests allow other memory clients to have better
memory access. When IPC is disabled, all plane read requests are sent at
high priority.

Changes since V1:
 - Remove commandline parameter to disable ipc
 - Address Paulo's comments
Changes since V2:
 - Address review comments
 - Set ipc_enabled flag
Changes since V3:
 - move ipc_enabled flag assignment inside intel_ipc_enable function
Changes since V4:
 - Re-enable IPC after suspend/resume
Changes since V5:
 - Enable IPC for all gen >=9 except SKL
Changes since V6:
 - fix commit msg
 - after resume program IPC based on SW state.
Changes since V7:
 - Modify IPC support check based on HAS_IPC macro (suggested by Chris)

Subject: drm/i915: Switch over to the LLC/eLLC hotspot avoidance hash mode for
 CCS

Use the LLC/eLLC hotspot avoidance mode for CCS on LLC machines. This is
reported to give better performance.

Testing has indicated that we don't need to enforce any massive 2 or 4
MiB alignment for all compressed resources even though there are still
plenty of stale comments in the spec suggesting that we do.

We do need to make sure every hardware unit that deals with the
compressed data uses the same hash mode.

Subject: drm/i915/cnp: Don't touch other PCH clock gating bits.

Don't touch other bits. My bad.

I haven't seen any case where those other bits appeard to be
set before we touch it, but it is safe to avoid touching
other bits we weren't told to touch.

Subject: drm/i915: Rename global i915 to i915_modparams

Our global struct with params is named exactly the same way
as new preferred name for the drm_i915_private function parameter.
To avoid such name reuse lets use different name for the global.

v5: pure rename
v6: fix

Subject: drm/i915/skl: Fix has_ipc on skl and document WaDisableIPC.

According to Spec for SKL+: "Isochronous Priority Control.
If enabled, Display sends demoted requests once the transition
watermark is reached. If transition watermark is not enabled,
Display sends demoted requests when the display buffer is full."

The commit 'e57f1c02155f ("drm/i915/gen9+: Add has_ipc flag in
device info structure")' introduced that as gen9+ but missing many
SKL Skus.

I believe the reason for that is Spec also mentions workarounds for
SKL-ALL: "IPC (Isoch Priority Control) may cause underflows
WA: Do not enable IPC in register ARB_CTL2"

It seems lame to add the feature and forever disable it,
but it will avoid a mistake of enabling it when we are reorganizing
the feature definitions on i915_pci.c later.

It will also allow us to probably extend that workaround for
other platforms.

Subject: drm/i915: disable GTT cache for 2M pages

When SW enables the use of 2M/1G pages, it must disable the GTT cache.

v2: don't disable for Cherryview which doesn't even support 48b PPGTT!

v3: explicitly check that the system does support 2M/1G pages

v4: split WA and decision logic

Subject: drm/i915: Separate RPS and RC6 handling for BDW

This patch separates RC6 and RPS enabling for BDW.
RC6/RPS Disabling are handled through gen6 functions.
PM Programming guide recommends a sequence within forcewakes to
configure RC6, RPS and ring frequencies in sequence. With this
patch the order is still maintained.

v2: Update sequence numbers in RC6 programming and comment about
intent of reset_rps during gen8_enable_rps. (Radoslaw)

v3: Rebase.

Subject: drm/i915: Name i915_runtime_pm structure in dev_priv as "runtime_pm"

We were using dev_priv->pm for runtime power management related state.
This patch renames it to "runtime_pm" which looks more apt.

From 9f817501bd7facfe2bffacd637f4332e5991e57a Mon Sep 17 00:00:00 2001
From: Sagar Arun Kamble
Date: Tue, 10 Oct 2017 22:30:05 +0100
Subject: drm/i915: Move rps.hw_lock to dev_priv and s/hw_lock/pcu_lock

In order to separate GT PM related functionality into new structure
we are updating rps structure. hw_lock in it is used for display
related PCU communication too hence move it to dev_priv.

From 562d9bae08a10335368bf54ea5cc7e4f6185bccc Mon Sep 17 00:00:00 2001
From: Sagar Arun Kamble
Date: Tue, 10 Oct 2017 22:30:06 +0100
Subject: drm/i915: Name structure in dev_priv that contains RPS/RC6 state as
 "gt_pm"

Prepared substructure rps for RPS related state. autoenable_work is
used for RC6 too hence it is defined outside rps structure. As we do
this lot many functions are refactored to use intel_rps *rps to access
rps related members. Hence renamed intel_rps_client pointer variables
to rps_client in various functions.

v2: Rebase.

v3: s/pm/gt_pm (Chris)
Refactored access to rps structure by declaring struct intel_rps * in
many functions.

Subject: drm/i915: Rename intel_enable_rc6 to intel_rc6_enabled

This function gives the status of RC6, whether disabled or if
enabled then which state. intel_enable_rc6 will be used for
enabling RC6 in the next patch.

v2: Rebase.

v3: Rebase.

Subject: drm/i915: Create generic function to setup LLC ring frequency table

Prepared intel_update_ring_freq function to setup ring frequency
for applicable platforms determined by macro HAS_LLC.

v2: Replaced NEEDS_RING_FREQ_UPDATE with HAS_LLC macro. (Chris)
    Added check while calling from intel_enable_gt_powersave.

v3: s/intel_update_ring_freq/intel_enable_llc_pstate and created
new placeholder function intel_disable_llc_pstate. (Chris)

Subject: drm/i915: Create generic functions to control RC6, RPS

Prepared generic functions intel_enable_rc6, intel_disable_rc6,
intel_enable_rps and intel_disable_rps functions to setup RC6/RPS
based on platforms.

v2: Make intel_enable/disable_rc6/rps static. (Chris)

v3: Added lockdep_assert_held(dev_priv->pcu_lock) in new generic
functions. (Chris)
Removed WARN_ON(&dev_priv->pcu_lock) from lower level functions as generic
function now has lockdep_assert. Rebase.

Subject: drm/i915: Introduce separate status variable for RC6 and LLC ring

Subject: drm/i915/cnl: WaRsUseTimeoutMode

Apparently RC6 residency is lower than expected
with EI mode for most of the cases on CNL A0, B0 and C0.

This Wa doesn't solve our lower residency, but I
believe it is better to have it since EI is not
expected to work by HW engineers anyways.

Subject: drm/i915: Calculate ironlake intermediate watermarks correctly, v2.

The watermarks it should calculate against are the old optimal watermarks.
The currently active crtc watermarks are pure fiction, and are invalid in
case of a nonblocking modeset, page flip enabling/disabling planes or any
other reason.

When the crtc is disabled or during a modeset the intermediate watermarks
don't need to be programmed separately, and could be directly assigned
to the optimal watermarks.

Changes since v1:
- Use intel_atomic_get_old_crtc_state. (ville)

Subject: drm/i915: Move init_clock_gating() back to where it was

Apparently setting up a bunch of GT registers before we've properly
initialized the rest of the GT hardware leads to these setting being
lost. So looks like I broke HSW with commit b7048ea12fbb ("drm/i915:
Do .init_clock_gating() earlier to avoid it clobbering watermarks")
by doing init_clock_gating() too early. This should actually affect
other platforms as well, but apparently not to such a great degree.

What I was ultimately after in that commit was to move the
ilk_init_lp_watermarks() call earlier. So let's undo the damage and
move init_clock_gating() back to where it was, and call
ilk_init_lp_watermarks() just before the watermark state readout.

This highlights how fragile and messed up our init order really is.
I wonder why we even initialize the display before gem. The opposite
order would make much more sense to me...

v2: Keep WaRsPkgCStateDisplayPMReq:hsw early as it really must
    be done before all planes might get disabled.
