[RFC-v2 0/9] Add support for mipi dsi cmd mode

[RFC-v2 0/9] Add support for mipi dsi cmd mode

[Vandita Kulkarni]

Fixed the comments on version1 RFC, basically fixing the
challenge on getting access to mipi dsi attributes like
is command mode enabled, and what should be the port for
reading TE and doing a frame update.
Thanks to Jani and Ville for their inputs on this.

Vandita Kulkarni (9):
  drm/i915/dsi: Define command mode registers
  drm/i915/dsi: Configure transcoder operation for command mode.
  drm/i915/dsi: Add vblank calculation for command mode
  drm/i915/dsi: Add cmd mode flags in display mode private flags
  drm/i915/dsi: Add check for periodic command mode
  drm/i915/dsi: Use private flags to indicate TE in cmd mode
  drm/i915/dsi: Configure TE interrupt for cmd mode
  drm/i915/dsi: Add TE handler for dsi cmd mode.
  drm/i915/dsi: Initiate fame request in cmd mode

There may have been a few naming nitpicks I could've had, but meh.

Pushed to dinq, thanks for the patch.

[RFC-v2 2/9] drm/i915/dsi: Configure transcoder operation for command mode.

[Vandita Kulkarni]

Configure the transcoder to operate in TE GATE command mode
and  take TE events from GPIO.
Also disable the periodic command mode, that GOP would have
programmed.

Do we have TE source specified in VBT or somewhere? I can live with this
*for now* but it does freak me out a bit that we might also be using the
utility pin for backlight PWM output. That would conflict magnificently.

Maybe at least add a FIXME comment about that?

You'll also need to disable the utility pin somewhere, else you'll get
warnings from assert_can_enable_dc6().

Do we have TE source specified in VBT or somewhere? I can live with this
*for now* but it does freak me out a bit that we might also be using the
utility pin for backlight PWM output. That would conflict magnificently.

Maybe at least add a FIXME comment about that?

You'll also need to disable the utility pin somewhere, else you'll get
warnings from assert_can_enable_dc6().

Adding TE flags and periodic command mode flags

we would be getting instead of vblanks in case of mipi dsi
command mode.

Might be useful to comment that one or the other is set if the crtc has
a DSI encoder that's operating in command mode, and both are unset
otherwise.

[Intel-gfx] [RFC-v2 5/9] drm/i915/dsi: Add check for periodic command mode

[Vandita Kulkarni]

If the GOP has programmed periodic command mode,
we need to disable that which would need a
deconfigure and configure sequence.

[RFC-v2 6/9] drm/i915/dsi: Use private flags to indicate TE in cmd mode

[Vandita Kulkarni]

On dsi cmd mode we do not receive vblanks instead
we would get TE and these flags indicate TE is expected on
which port.

I'd hide this more inside gen11_dsi_configure_te():

	if (gen11_dsi_configure_te(crtc))
		return 0;

and make that function early return false if neither TE flag is set. It
also doesn't have to check for gen, because you can trust those flags
are only set where it matters.

Not really happy about this one, but perhaps acceptable for now.

[RFC-v2 8/9] drm/i915/dsi: Add TE handler for dsi cmd mode.

[Vandita Kulkarni]

In case of dual link, we get the TE on slave.
So clear the TE on slave DSI IIR.

Please follow the same style as nearby:

        if (gen11) {
                tmp_mask = iir & (DSI0_TE | DSI1_TE);
                if (tmp_mask) {
                        gen11_dsi_te_interrupt_handler(dev_priv, tmp_mask);
                        found = true;
                }
        }

Even if that's functionally the same, I think it's cleaner to only pass
the relevant masked bits to the handler.

Please follow the same style as nearby:

        if (gen11) {
                tmp_mask = iir & (DSI0_TE | DSI1_TE);
                if (tmp_mask) {
                        gen11_dsi_te_interrupt_handler(dev_priv, tmp_mask);
                        found = true;
                }
        }

Even if that's functionally the same, I think it's cleaner to only pass
the relevant masked bits to the handler.

[RFC-v2 9/9] drm/i915/dsi: Initiate fame request in cmd mode

[Vandita Kulkarni]

In TE Gate mode, on every flip we need to set the
frame update request bit. After this  bit is set
transcoder hardware will automatically send the
frame data to the panel when it receives the TE event.
