Adding the Kabylake new DMC firmware i915_dmc_info doesn't expose DC3 -> DC5 and DC5 -> DC6 counts.

    drm/i915: Show dmc debug registers on Kabylake

Comment 2 Nathan Ciobanu 2017-05-10 02:28:04 UTC

Thanks for the quick patch Mika, unfortunately the first version of the KBL DMC firmware was 1.1 so CSR_VERSION macro should check for >1.1 in the KBL case.

Comment 3 Mika Kuoppala 2017-05-11 11:52:42 UTC

All the released kbl firmwares support the registers in question. So
the version check is not relevant.

Comment 4 Nathan Ciobanu 2017-05-13 00:52:15 UTC

Sorry, my bad. It works fine. I'm closing this bug fixed by Mika's patch.
