BKL & latency

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I have read that with each new kernel release, the Big Kernel Lock
(BKL) is gradually being removed from the core kernel code.

Just out of interest, I was wondering if this has an impact on the RT patch?

In particular,
 - does the RT patch have any connection with the BKL?
 - presumably the BKL removal will reduce the average latency of the
unpatched kernel?
 - is the BKL currently a source of considerable latency?
 - will the BKL removal make the RT patch considerably smaller/simpler?
 - has the RT patch effectively been removing the BKL since day 1, or
does it just make the BKL a pre-emptible lock?

Many thanks,
Tony
