this is odd.  it indicates that a skylake cpu (
https://ark.intel.com/content/www/us/en/ark/products/88184/intel-core-i5-6500-processor-6m-cache-up-to-3-60-ghz.html)
but the GPU is calling itself kabylake generation.

i wonder if there's something fixed in newer drm that
handles this situation.  might be worth looking at
the upstream code around this part now.  does it add
additional types for skylake vs kabylake?  when i
patched in the kabylake support in 2018, i had made it
mostly match the upstream version from then.
