Hi, my new computer reports at boot time that some graphics firmware is missing:
[ 1.158505] i915 0000:00:02.0: firmware: failed to load i915/kbl_dmc_ver1_04.bin (-2) [ 1.158507] firmware_class: See https://wiki.debian.org/Firmware for information about missing firmware [ 1.158508] i915 0000:00:02.0: Direct firmware load for i915/kbl_dmc_ver1_04.bin failed with error -2 [ 1.158509] i915 0000:00:02.0: Failed to load DMC firmware i915/kbl_dmc_ver1_04.bin. Disabling runtime power management. [ 1.158510] i915 0000:00:02.0: DMC firmware homepage: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915 LXDE works despite these messages. The web says that DMC is about power saving in Intel graphics. https://01.org/linuxgraphics/downloads/firmware "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." The desired firmware file seems to be indeed available at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915/kbl_dmc_ver1_04.bin but the given Debian wiki page is refering to Debian 8 as newest and also i cannot find a tangible hint how to install such firmware after the initial installation was already done (from netinst). My questions: - How desirable or undesirable is to install this particular firmware ? - If i decide to do it: how to proceed ? Have a nice day :) Thomas
