[PATCH v2 0/2] drm/i915/intel_dsi: Read back pclk set by GOP and use that as plck

[Hans de Goede]

Hi All,

I've send v1 of this a while ago. Unfortunately I did not have time
to respin this until now.

This version uses intel_encoder_current_mode() as suggested in the
discussion of v1. This allows dropping 2 of the 4 original patches and
makes the remaining patches quite small :)

Regards,

Hans

[PATCH v2 1/2] drm/i915/intel_dsi: Move initialization of encoder variables up a bit

[Hans de Goede]

Move the initialization of encoder variables a bit higher inside the
intel_dsi_init() function. So that can call intel_encoder_current_mode()
from intel_dsi_vbt_init().

This is a preparation patch for reading back the GOP configured pclk
from intel_dsi_vbt_init().

[PATCH v2 2/2] drm/i915/intel_dsi: Read back pclk set by GOP and use that as pclk v2

[Hans de Goede]

On BYT and CHT the GOP sometimes initializes the pclk at a (slightly)
different frequency then the pclk which we've calculated.

This commit makes the DSI code read-back the pclk set by the GOP and
if that is within a reasonable margin of the calculated pclk, uses
that instead.

This fixes the first modeset being a full modeset instead of a
fast modeset on systems where the GOP pclk is different.

Changes in v2:
-Use intel_encoder_current_mode() to get the pclk setup by the GOP

I assume we don't do the fast path because intel_pipe_config_compare()
returns false due to crtc_clock and port_clock mismatch. The dmesg
should tell you the reason with drm.debugs enabled.

Now, the clock checks are already "fuzzy", and should account for slight
variations. I think the goal was the same as here, plus IIUC we may lose
some accuracy on the hardware roundtrip.

Please try adding more tolerance in intel_fuzzy_clock_check() and see if
that helps. The code looks like it allows 5% diff, but it's 2.5%.

Regardless of whether we end up changing the tolerance or adjusting the
state based on the hardware readout or what, I think doing the
adjustment in intel_dsi_vbt.c init is the wrong place. We shouldn't have
anything that depends on accessing the hardware there. I believe that's
what Ville was trying to say in [1].

BR,
Jani.

As I think I mentioned already last time (but that was a while ago,
so I understand you cannot remember the details), the problem is these
checks from intel_pipe_config_compare():

         PIPE_CONF_CHECK_X(dsi_pll.ctrl);
         PIPE_CONF_CHECK_X(dsi_pll.div);

> Now, the clock checks are already "fuzzy", and should account for slight

The check I quoted above are basically doing a non-fuzzy port_clock check,
we already do a fuzzy port_clock check, so maybe we should just drop them?

If you agree with dropping these 2 in essence non-fuzzy port-clock checks:

         PIPE_CONF_CHECK_X(dsi_pll.ctrl);
         PIPE_CONF_CHECK_X(dsi_pll.div);

Then we won't need this state adjustment.

But in case you do want to keep these, then were should the adjustment be done?

Keep in mind that the pclk is initially calculated in intel_dsi_vbt.c
and then immediately used to calculate a bunch of other settings such as
intel_dsi->lp_byte_clk, prepare_cnt, etc. So there really is no other
place were we can reasonably do this.

Regards,

Hans

We still want to do these checks when validating a modeset afterwards, but
for the fuzzy case we need to cut them out indeed. Similar to what we do
for the some of the other fastboot registers already with the if (!adjust)
condition.

I guess the trick here is making sure we pick the right set of registers
... Maybe we want to make all the pll low-level state like that (so both
dsi_pll and dpll_hw_state)?

Cheers, Daniel
