Logs on Librem 13v4 up-to-date report failure to load i915/skl_dmc_ver1_27.bin with error -2. This was diagnosed by mladen in another post entitled “Firmware failed to load” as missing firmware. That seems reasonable and my laptop works fine without the firmware.
Intel web site says DMC “provides additional graphics low-power idle states. It provides capability to save and restore display registers across these low-power states independently from the OS/Kernel.” That explains why it is firmware-related.
I’m curious why this firmware is missing and if it could be related to excessive power consumption on battery that I experience from time to time. Is a PureOS bug report present or deserve to be created?
