CC'ing linux-numa. I emailed it to linux-kernel but forgot to 'CC' linux-numa. Please CC 'linux-kernel' while replying.
Hello,
On a NUMA host, if a driver calls __get_free_pages() then
it will eventually invoke ->alloc_pages_current(..). The comment
above/within alloc_pages_current() says 'current->mempolicy' will be
used.So what memory policy will kick-in if the driver is trying to
allocate some memory blocks during driver load time(say from probe_one)? System-wide default policy,correct?
What if the driver wishes to i) stay confined to a 'cpulist' OR ii) use a different mem-policy? How
do I achieve this?
I will choose the 'cpulist' after I am successfuly able to affinitize the MSI-X vectors.
regards
Rick
