[PATCH 3 of 5] Linux pvops: evtchn delivery for legacy interrupts
Hi all, this patch sets the callback to receive evtchns from Xen, using the callback vector delivery mechanism. It also sets up mapping for GSIs to PIRQs, using exactly the same code path as in the dom0 case. This allows the guest to receive evtchns in place of interrupts, avoiding expensive EOIs. Finally this p... 9 Mar 2010 11:11
[PATCH SERIES v2] enhanced PV on Xen HVM
Hi all, this patch series is derived from an earlier version of Shen's "PV extension of HVM" patch series. It tries to achieve two goals: - enable PV devices in Linux running in a Xen HVM domain; - receive evtchns in place of interrupts to avoid expensive EOIs. The main difference between the two patch seri... 9 Mar 2010 11:11
[PATCH 4 of 5] Linux pvops: pci passthrough support
Hi all, this patch makes few changes to the xen pci functions to handle pirq remapping of interrupts belonging to pci passthrough devices: - disable pcifront and MSIs when running on HVM the former is not meant to be used while the latter are not supported yet - change xen_allocate_pirq to take the pirq as a ... 9 Mar 2010 11:11

The compiler can inline the sysrq calls such that they are entirely a NOP if CONFIG_MAGIC_SYSRQ is not set. This is not the best way to do what you want.
