For power state residency problems could you please always provide also the
output of the followings, captured at the moment where you expect some non-zero
residency (all ran as root):

lspci -vvk
lsmod

for d in /sys/devices/pci*/0*; do \
  grep . $d/power/{control,runtime_usage,runtime_suspended_time}; \
done

sleep 5

for d in /sys/devices/pci*/0*; do \
  grep . $d/power/{control,runtime_usage,runtime_suspended_time}; \
done

cat /sys/kernel/debug/dri/0/i915_power_domain_info
cat /sys/kernel/debug/dri/0/i915_dmc_info

<linux_src>/tools/power/x86/turbostat --debug sleep 5
