Dear coreboot folks,
please make sure to rebuild the utility cbmem with commit 08e920e5 (util/cbmem: Scale time stamp values correctly) [1]. There was a regression present for some months, causing the resulting time stamps to be in milliseconds instead of microseconds.
FYI: This regression was only observed on x86 platforms which don't provide tsc_freq_mhz(). Because of that, the cbmem utility fell back to using /sysfs on linux which had a unit issue from the commit Paul referenced.
Most of us probably didn’t notice, because cbmem is rarely rebuild. For the others, they were happy, seeing their boot time was a thousand times faster. ;-)
Big thanks to Aaron and Martin helping (doing) the fix.
Thanks,
Paul
