[PATCH] drm/i915/psr: Adds psrwake options for all platforms

[PATCH] drm/i915/psr: Adds psrwake options for all platforms

[vathsala nagaraju]

From: Vathsala Nagaraju <vathsala.nagaraju@intel.com>

Adds new psrwake options defined in the below table.
Platform	PSR wake options vbt version
KBL/CFL/WHL	All
SKL		All PV releases (Check for 203+ might help but cannot be foolproof)
BXT		Uses old interpretation.
CNL/ICL+	All
GLK		All

For SKL, we will continue to use older interpretation for the above reason.

v2: Jani
    Keep the bdb version check.

Thanks for the patch and review, pushed to dinq with the checkpatch
warnings fixed while at it.

Let's hope this works for most machines out there.

It'd be easier to distinguish newer updated patches if you use version
numbers.

[PATCH] drm/i915/psr: Adds psrwake options for all platforms

[vathsala nagaraju]

From: Vathsala Nagaraju <vathsala.nagaraju@intel.com>

Adds new psrwake options defined in the below table.
Platform	PSR wake options vbt version
KBL/CFL/WHL	All(205+)
BXT		Uses old interpretation.
CNL/ICL+	All(205+)
GLK		All(205+)
SKL		All PV releases (Check for 205+ might help but cannot be foolproof)

We will continue with newer interpretation for SKL from 205.

v2: Jani
    Keep the bdb version check.
v3:
    Apply newer version for skl from 205+(DK).
    Add (version check && platform list) (Jani).
    Add bdb version for each platform in commit message(DK).

Using the version number as a guard makes sense but this means we need
a version number that's applicable to all platforms.

Vathsala,
Can you please confirm if all platforms that you want to use the new
mapping for have version numbers >= 205?

If that's the case, it should be easy to change the check to

if (version >= 205 && (IS_GEN9_BC() || IS_GEMINILAKE() || INTEL_GEN()
>= 10))

Whatever the version, I want that to be required always. i.e.

	if (version >= N && (bunch of other conditions))

*not*

	if (version >= N || (bunch of other conditions))

Re: [PATCH] drm/i915/psr: Adds psrwake options for all platforms

[Nagaraju, Vathsala]

+ Ashutosh(VBT team)   + maulik

209 is confirmed version on kbl both by vbt team (Maulik) and google, so we had used it.

DK's suggestion is 
if ((bdb->version >= 203 && IS_GEN9_BC(dev_priv)) ||
IS_GEMINILAKE(dev_priv) ||  INTEL_GEN(dev_priv) >= 10) {
/* new mapping */

As per Ashutosh, 203 Is not the right version, 205 is fine , but user can still provide decimal value for SKL.
Jani/Rodrigo, should we use 205 for SKL or  drop SKL from the new mapping?

We are not going to get this right for all combinations, the best we
can do is make sure things work in most cases. I prefer to err on the
side of using the new mapping because when translated incorrectly, 3
out of 4 values lead to >= intended training time. Given the fact that
SKL PV releases also used the new mapping, I suggest you do this

if ((bdb->version >= 203 && IS_GEN9_BC(dev_priv)) ||
IS_GEMINILAKE(dev_priv) ||  INTEL_GEN(dev_priv) >= 10) {
/* new mapping */

}

I don't know what the basis for the current check for version 209 is,
other than it was the version on the KBL you tested.

I did a copy paste of the table provided by vbt team, will edit for skylake
Since VBT team cannot confirm version for SKL ,so skipping for skylake.

Why not change the version check to >= 203, if that's what PV releases
had as per your commit message? With the current code, Linux and
Windows set 500 us and 2.5 ms respectively on my laptop.

That doesn't match your commit message.

Sure. For SKL , shall we use older interpretation for all bdb version as 
vbt team cannot confirm bdb version for SKL?

Please keep the version check.

Please tell anyone who asks, and also those who don't, that *all* of the
VBT changes should be based on the *version*, and *none* of them should
be based on the *platform*.

[PATCH] drm/i915/psr: Adds psrwake options for all platforms

[vathsala nagaraju]

From: Vathsala Nagaraju <vathsala.nagaraju@intel.com>

Adds new psrwake options defined in the below table.
Platform	PSR wake options vbt version
KBL/CFL/WHL	All
SKL		All PV releases (Check for 203+ might help but cannot be foolproof)
BXT		Uses old interpretation.
CNL/ICL+	All
GLK		All

For SKL, we will continue to use older interpretation for the above reason.
