[Xen-devel] [PATCH] Updated Local APIC Initialization
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. -Natasha Signed-off-by: Natasha Jarymowycz <natasha@us.ibm.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
