RHBZ#: ------ https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=195533 Description: ------------ This patch is to enable NUMA capability on the PAE 32-bit kernel. Upstream Status: ---------------- For some NUMA machines, such as the IBM x460 to take advantage of this, some extra kernel patches need to be applied. They are being worked upstream so I am not yet posting them here. My thought is to first see if turning this build option breaks non-NUMA machines and then follow up with other NUMA boxes and see how they fare (and if they need patches). Test Status: ------------ NUMA: IBM x460 with other patches (BZ 184806) non-NUMA: IBM Netfinity x232, LS-20, IBM ThinkPad T41p, IBM IntelliStation Z Pro, ProLiant DL360 G4p.
