[Intel-gfx] [PATCH v2 0/8] drm/i915: SAGV block time fixes

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Try to fix SAGV block time handling:
- zero means no SAGV
- avoid integer overflows
- slightly better debug logs
- assorted cleanups

v2: reorder to allow stable backport of the zero->no SAGV patch
    Fix/clean some PSF GV stuff as well that caught my eye

Ville Syrjälä (8):
  drm/i915: Treat SAGV block time 0 as SAGV disabled
  drm/i915: Rework SAGV block time probing
  drm/i915: Probe whether SAGV works on pre-icl
  drm/i915: Reject excessive SAGV block time
  drm/i915: Rename pre-icl SAGV enable/disable functions
  drm/i915: Fix PSF GV point mask when SAGV is not possible
  drm/i915: Unconfuses QGV vs. PSF point masks
  drm/i915: Rename QGV request/response bits

For modern platforms the spec explicitly states that a
SAGV block time of zero means that SAGV is not supported.
Let's extend that to all platforms. Supposedly there should
be no systems where this isn't true, and it'll allow us to:
- use the same code regardless of older vs. newer platform
- wm latencies already treat 0 as disabled, so this fits well
  with other related code
- make it a bit more clear when SAGV is used vs. not
- avoid overflows from adding U32_MAX with a u16 wm0 latency value
  which could cause us to miscalculate the SAGV watermarks on tgl+

Should we may be add this to intel_has_sagv? I thought this was supposed to tell,
if SAGV is supported or not. Should we just call it hear as well, may be..
Now we kinda making it less obvious.

We already use intel_has_sagv() to see if we should zero out the
block time. I don't think I want to make it a full circle.

[Intel-gfx] [PATCH v2 2/8] drm/i915: Rework SAGV block time probing

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

I'd like to see the SAGV block time we got from the mailbox
in the logs regardless of whether other factors prevent the
use of SAGV.

So let's adjust the code to always query the SAGV block time,
log it, and then reset it if SAGV is not actually supported.

[Intel-gfx] [PATCH v2 3/8] drm/i915: Probe whether SAGV works on pre-icl

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Instead of leaving the SAGV enable/disable to the first commit
let's try to disable it first thing to see if we can do it or
not (disabling SAGV is a safe thing to at any time). This avoids
running the code in this funny intermediate state where we don't
know if SAGV is available or not.

[Intel-gfx] [PATCH v2 4/8] drm/i915: Reject excessive SAGV block time

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

If the mailbox returns an exceesively large SAGV block time let's just
reject it. This avoids having to worry about overflows when we add the
SAGV block time to the wm0 latency.

We shall put the limit arbitrarily at U16_MAX. >65msec latency
doesn't really make sense to me in any case.

[Intel-gfx] [PATCH v2 5/8] drm/i915: Rename pre-icl SAGV enable/disable functions

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Give the pre-icl SAGV control functions a skl_ prefix instead
of the intel_ prefix to make it a bit more clear that they
are not some kind of universal things that can be called on
any platform. Also make the functions void since we never
use the return value anyway.

[Intel-gfx] [PATCH v2 6/8] drm/i915: Fix PSF GV point mask when SAGV is not possible

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Don't just mask off all the PSF GV points when SAGV gets disabled.
This should in fact cause the Pcode to reject the request since
at least one PSF point must remain enabled at all times.

[PATCH v2 6/8] drm/i915: Fix PSF GV point mask when SAGV is not possible

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Don't just mask off all the PSF GV points when SAGV gets disabled.
This should in fact cause the Pcode to reject the request since
at least one PSF point must remain enabled at all times.

Good point, however I think this is not the full fix:

BSpec says:

"At least one GV point of each type must always remain unmasked."

and

"The GV point of each type providing the highest bandwidth 
 for display must always remain unmasked."

So I guess we should then also choose thr PSF GV point with
the highest bandwidth as well.

The spec says PSF GV is fast enough to now stall the display data
fetch so we don't need to restrict the PSF points here.

But why it asks to ensure that we have the PSF GV of highest bandwidth to
stay always unmasked then?

I presume so you don't lock the memory bandwdith to some lower
performance point and hurt all the other things that need
memory bandwidth. Either that or there is some internal
implementation detail that simply doesn't work if you try to
permanently run at a lower performance point.

[Intel-gfx] [PATCH v2 7/8] drm/i915: Unconfuses QGV vs. PSF point masks

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use separate bitmasks for QGV vs. PSF GV points during
the computation. Makes the whole thing a lot less confusing.

[Intel-gfx] [PATCH v2 8/8] drm/i915: Rename QGV request/response bits

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Name all the ICL_PCODE_SAGV_DE_MEM_SS_CONFIG request/response
bits in a manner that we can actually understand what they're
doing.
