On my Thinkpad laptop I am seeing this error every time after the boot in the dmesg output:
"Error parsing PCC subspaces from PCCT"
The attached log files should reveal more. I have no idea what it means but seems serious. Hope you can solve this for once and all?

[Impact]
A scary-looking message appears in dmesg in several places during boot:
"Error parsing PCC subspaces from PCCT"
[Test Case]
dmesg | grep "Error parsing PCC subspaces"
[Fix]
Resolved in upstream commit that cleanly cherry-picks back to bionic:
8f8027c5f935 mailbox: PCC: erroneous error message when parsing ACPI PCCT
[Regression Risk]
PCC is a generic ACPI-defined mechanism for the OS and firmware to communicate. Since the fix does change how the tables are parsed, regression scenarios could include breakages in PCC clients (things that use this layer to communicate to firmware). The only Kconfig option I see in bionic's source that depends on CONFIG_PCC is the CPPC library, which provides ACPI CPU performance management used by the cppc-cpufreq driver and is used by the scaling driver/governor for Sandy bridge processors.
Tested on an Nvidia DGX system. This is an upstream fix, so any regressions will have upstream support. |
