Title:
[18.04] GLK hang after a while
Status in intel:
Triaged
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Bionic:
In Progress
Bug description:
SRU Justification
Impact: i915 lacks information about the glk_dmc_ver1_04.bin firmware
file in modinfo, so it is not included in the initrd along with the
i915 driver. Thus the firmware does not get loaded. Loading the
firmware is said to prevent a hang.
Fix: Add a MODULE_FIRMWARE statement for the firmware.
Test Case: Without the firmware there will be a "Direct firmware load
for i915/glk_dmc_ver1_04.bin failed with error -2" line in dmesg. With
the firmware there is no such message.
Regression Potential: Minimal. Will only be loaded by i915 for
specific hardware, and loading the firmware is known to fix a hang.
