[v9,0/5] Add support for Gen 11 pipe color features

Message

Shankar, Uma Feb. 11, 2019, 1:50 p.m. UTC

This patch series adds support for Gen11 pipe degamma, CSC
and gamma hardware blocks.

CRC checks are not working for 10bit gamma but works for 8bit
pallete modes which seems to be due to some rounding errors in
pipe. Also there is a corner case where Lut precision is increased
to 3.16, hence its not possible to accurately represent 1.0 which
will require 17 bits. Support for extending the ABI is already in
discussion in below series:
https://patchwork.freedesktop.org/patch/249771/

ToDo: Support for Multi Segmented Gamma will be added later.

v2: Addressed Maarten's review comments and re-ordered the patch
series.

v3: Addressed Matt's review comments. Removed rmw patterns
as suggested by Matt.

v4: Addressed Matt's review comments.

v5: Addressed Matt's, Ville and Jani Nikula's review comments.

v6: Addressed Matt and Ville's review comments. Extended GLK 
degamma function and merged ICL degamma support to that. Handled
pipe output csc separately along with regular pipe csc. Dropped
gamma_mode removal patch as Ville is using that to refactor the
gamma handling. This series may need a rebase on top of Ville's
below series:
https://patchwork.freedesktop.org/series/55081/. 

v7: Rebased the series on top of Ville's color management
cleanup and state refactoring series. Addressed Matt's review
comments and aligned state handling as per atomic design.

v8: Fixed macro alignment and some checkpatch warnings.

v9: Fix Maarten's review comments and added his RB tag.

This is due to CRC mismatch which happens due to rounding issues in pipe.
So, crc may not match exactly. These tests rely on crc to match which may not happen here.

We are extending and re-using code from GLK. Currently GLK has all this disabled in driver and hence
tests  were skipped. But ideally it should not, since its working fine just the crc mismatch are there.
It is same for ICL.

Pipe output however is correct and I have verified on simulation that we get exact bit wise match.
This is what even we are facing on some of the planar format testing. 

For this series, I believe we can mark these tests as known issues with how current
hardware behaves. We can create a separate task and work within team to come up with different ideas
to test these in CI.

Uma Shankar

At least one problem is that the uapi doesn't allow us to say 1.0
which is what we need for all the interpolated gamma modes. Not sure
if the test is calculating the other entries correctly either for
these interpolated modes.

But not sure if this has anything to do with the crc mismatches.

Anyways series looks all right to me:
Acked-by: Ville Syrjälä <[e-mail]>

A few things we probably would want to do as a followup:
- abstract the output csc vs. pipe csc a bit to avoid
  the code duplication. Maybe parametrize the registers,
  or just add a function for each that takes in the coeffs
  as a parameter.
- readout seems to be missing for the new crtc state stuff

Yes I added as part of plane color series to extend the ABI. This definitely will be needed
not just for 1.0 but even for 3.0 and 7.0 stuff. But lack of userspace support stalled that.
I believe the test is getting values right (except for 1.0) since bmp output is matching on simulation.

>But not sure if this has anything to do with the crc mismatches.

I tried to experiment hardcoding inside driver just to confirm this part, but doesn't seem to help.

Sure, will create some internal task to track these and work on it.

Thanks Ville for review and the ack.
