Subject: [PATCH] MIPS: BCM63XX: sync mips counter during cpu bringup
|
|
|
|
We are using the mips counters as the clock source, so we need to ensure
|
|
they are synced, else e.g. gettimeofday will return different values
|
|
depending on which core it was run.
|
|
|
|
Observed difference was about 8 seconds, causing ~8 seconds ping or time
|
|
running backwards for some programs.
