The attached patch apic.patch updates xen/arch/x86/apic.c so that
it is based on linux 2.6.10 code. A few changes made to linux
required reworking functions in other files as well so I held off
on those changes. For example, setup_APIC_timer(void *) changed
to setup_APIC_timer(unsigned int). The change has no real bearing
on the Xen code -- it's just a question of how close to
linux one wants to be. However, that change goes with a change to
smp_call_function which would affect quite a few other files/functions
so I left it as is. Most of the other changes are trivial.
xen/ac_timer.h was included but not needed by apic.c so I removed
it from the list of #includes.
The new apic.c includes two new files: asm/io_ports.h and
asm/mach_apic.h. Patches to create those files are included as well.
I tested the changes by booting xen on my machine. "xm dmesg" showed
a trivial change to the cpu speed detected:
< (XEN) Detected 2992.616 MHz processor.
(XEN) Detected 2992.596 MHz processor.
< (XEN) ..... CPU clock speed is 2992.5438 MHz.
(XEN) ..... CPU speed is 2992.5282 MHz.
I also created a second domain where I created a large file with dd
and copied it over the "network" to domain 0. There were no interrupt
error messages and nothing out of the ordinary occurred.
