[PATCH i-g-t 1/7] lib/igt_kms: don't run on unsupported platform

[Kunal Joshi]

kmd exposes debugfs for all the platforms, so add
a check in igt

v2: dsc is required for gen12, so test only
for devid 13 and 13+ (Ankit)

This is not correct, KMD exposes the debugfs if display ver >= 11 and 
the connector type is eDP or DP [*].

Hello Bhanu,

Yes we need this commit as below reason
if output is already assigned to pipe D, then forcing big joiner is not 
having any affect.

How connector_attr_set_debugfs() is different than 
connector_attr_set_sysfs()?

---------------------------------^
This will reset all connectors, Instead of resetting all connectors I'm 
expecting to reset a particular one. Maybe we can take this as a 
separate activity.

AFAIK, igt_display_reset() will clear associated pipe on all outputs. 
And we are associating last pipe (D) to the selected connector. The 
immediate commit will catch the bigjoiner constraint.

Still, I don't see any advantage of having this extra commit, am I 
missing anything?

Thanks bhanu for checking this out,
Will update the commit, but still we need to keep <13 condition,
As DSC is needed for <13.


Hot to know from Ankit

bool intel_dp_joiner_needs_dsc(struct drm_i915_private *i915, bool use_joiner)
{
        /*
         * Pipe joiner needs compression up to display 12 due to bandwidth
         * limitation. DG2 onwards pipe joiner can be enabled without
         * compression.
         */
        return DISPLAY_VER(i915) < 13 && use_joiner;
}

But will edit comment.

Thanks and Regards

Hmm, not sure how could this work still,
Will assign proper value to idx in next revision.

[PATCH i-g-t 1/7] lib/igt_kms: don't run on unsupported platform

[Kunal Joshi]

dipslay <=12 needs dsc enabled for pipe joiner,
add a check in IGT for the same

v2: dsc is required for gen12, so test only
    for devid 13 and 13+ (Ankit)
v3: update comment (Bhanu)

For display 12 joiner needs DSC also. Due to this we cannot force 
bigjoiner on machines that are not connected to DSC sinks.

So perhaps I guess it would be better to test for 13 and above, as we 
will not require DSC for that.

kmd exposes debugfs for all the platforms, so add
a check in igt
