| | | | | | | | | | | | | | | | | | | | | | | | xen-platform-pci fails to load w/ undefined symbols for some of the sched_op hypercalls in machine_reboot.c. This adds them to xencomm mini to allow them to be called from modules. Signed-off-by: Alex Williamson <alex.williamson@hp.com>

* | [IA64] Skip MCA setup on domUAlex Williamson2007-04-111-0/+4
| | | | | | | | | | | | | | | | | | This effectively automates passing the nomca flag to domUs, preventing them from setting up CMC/CPE interrupts. This saves 3 dynamic IRQs per processor and allows us to get domUs up to 64 vCPUs without increasing the number of dynamic IRQs available. Signed-off-by: Alex Williamson <alex.williamson@hp.com>

* linux: improve x86 page table handling performancekfraser@localhost.localdomain2007-04-054-134/+218
| | | | | | | | | | | | | | | Where possible, - use hypercalls instead of writing to read-only pages - fold TLB flushes into page table update hypercalls - on PAE, use single-access updates instead of two-access ones The single change to PAE pte_clear() yields a 25-30% boost for kernel builds on a 4x2x2 CPUs, 8Gb box; the other changes together yield improvements of 2-5%. Also, adjust backward compatibility handling in a few more places. Signed-off-by: Jan Beulich <jbeulich@novell.com>
