Subject: [PATCH v5] Spread boot time scrubbing across available CPUs.
Date: Wed, 4 Jun 2014 09:29:35 -0400 [thread overview]
Message-ID: <1401888576-30027-1-git-send-email-konrad.wilk@oracle.com> (raw)
Please see v5 of this patchset. It should have all review comments addressed.
I did change the algorithm for the NUMA-node-but-no-CPUs code. It now
picks the closest NUMA node CPUs to do the scrubbing. If that node
does not have any CPUs it will continue on until it finds something - or
it falls back on the first node. And if the first node has no CPUs either
- it will just pick the BSP and call it a day. That hopefully should take
care of it running on broken hardware.
I've also cross compiled it on ARM but hadn't yet run the emulator to
make sure it works right. I figured I would do that once the x86 folks
are comfortable with the patch.
Thank you everybody for reviewing the patch over and over.
