drm/i915: Include G4X/VLV/CHV in self refresh status

2015-06-04T08:19:38+00:00

Add all missing platforms handled by intel_set_memory_cxsr() to the
i915_sr_status debugfs entry.

v2: Add G4X too. (Ville)
    Clarify the change also affects CHV. (Ander)

drm/i915: Relax RPS contraints to allows setting minfreq on idle

2015-03-20T10:48:13+00:00

When we idle, we set the GPU frequency to the hardware minimum (not user
minimum). We introduce a new variable to distinguish between the
different roles, and to allow easy tuning of the idle frequency without
impacting over aspects of RPS. Setting the minimum frequency should be a
safety blanket as the pcu on the GPU should be power gating itself
anyway. However, in order for us to do set the absolute minimum
frequency, we need to relax a few of our assertions that we do not
exceed the user limits.

v2: Add idle_freq
v3: Init idle_freq for vlv and add a bunch of WARNs

drm/i915: Exit early from psr_status if PSR is not supported by the device

2015-03-17T21:30:10+00:00

Static analysis was complaining that a path existed where we could use
stat[] uninitialized. Fix this by simplifying the logic to exit early if
PSR isn't supported.

drm/i915/chv: Add CHV HW status to SSEU status

2015-03-17T21:30:05+00:00

Collect the currently enabled counts of slice, subslice, and
execution units using the power gate control ack message
registers specific to Cherryview.

Slice/subslice/EU info and hardware status can now be
determined for CHV, so allow the debugfs SSEU status dump
to proceed for CHV devices.

drm/i915: Remove ironlake rc6 support

2015-03-17T21:29:59+00:00

Apparently, this has never worked reliably and is currently disabled. Also, the
gains are not particularly impressive. Thus rather than try to keep unused code
from decaying and having to update it for other driver changes, it was decided
to simply remove it.

drm/i915: Add debugfs entry for DRRS

2015-03-17T21:29:55+00:00

Adding a debugfs entry to determine if DRRS is supported or not

V2: [By Ram]: Following details about the active crtc will be filled
	in seq-file of the debugfs
	1. Encoder output type
	2. DRRS Support on this CRTC
	3. DRRS current state
	4. Current Vrefresh
Format is as follows:
CRTC 1:  Output: eDP, DRRS Supported: Yes (Seamless), DRRS_State: DRRS_HIGH_RR, Vrefresh: 60
CRTC 2:  Output: HDMI, DRRS Supported : No, VBT DRRS_type: Seamless
CRTC 1:  Output: eDP, DRRS Supported: Yes (Seamless), DRRS_State: DRRS_LOW_RR, Vrefresh: 40
CRTC 2:  Output: HDMI, DRRS Supported : No, VBT DRRS_type: Seamless

V3: [By Ram]: Readability is improved.
	Another error case is covered [Daniel]

V4: [By Ram]: Current status of the Idleness DRRS along with
	the Front buffer bits are added to the debugfs. [Rodrigo]

V5: [By Ram]: Rephrased to make it easy to understand.
	And format is modified. [Rodrigo]

V6: [By Ram]: Modeset mutex are acquired for each crtc along with
	renaming the Idleness detection states  [Daniel]

drm/i915: Make for_each_plane() take dev_priv as argument

2015-03-17T21:29:49+00:00

Implicit usage of local variables in macros isn't exactly the greatest
thing in the world, especially when that variable is the drm device and
we want to move towards a broader use of the i915 device structure.

Let's make for_each_plane() take dev_priv as its first argument then.
