Author: cherry Date: Tue Oct 30 21:04:16 2012 New Revision: 242376 URL: http://svn.freebsd.org/changeset/base/242376 Log: - Add a temporary MI shim for do_div(). This is suboptimal but functions and allows boot to proceed. - While processing system time, update timestamp from local vcpu instead of vcpu0 Approved by: gibbs (implicit) Modified: projects/amd64_xen_pv/sys/amd64/xen/clock.c Modified: projects/amd64_xen_pv/sys/amd64/xen/clock.c ============================================================================== --- projects/amd64_xen_pv/sys/amd64/xen/clock.c Tue Oct 30 21:04:12 2012 (r242375) +++ projects/amd64_xen_pv/sys/amd64/xen/clock.c Tue Oct 30 21:04:16 2012 (r242376) @@ -160,7 +160,7 @@ SYSCTL_INT(_machdep, OID_AUTO, xen_disab __asm__ __volatile__("rdtsc" : "=A" (val)) #else /* !__amd64__ */ -#define do_div(n,base) do {} while(0); /* XXX: TODO */ +#define do_div(n,base) (n) = (n)/(base) /* XXX: TODO - assembler optimise */ #define NS_PER_TICK (1000000000ULL/hz) #endif /* !__amd64__ */ @@ -516,7 +516,7 @@ startrtclock() /* initialize xen values */ __get_time_values_from_xen(); - processed_system_time = per_cpu(shadow_time, 0).system_timestamp; + processed_system_time = per_cpu(shadow_time, smp_processor_id()).system_timestamp; __cpu_khz = 1000000ULL << 32; info = &HYPERVISOR_shared_info->vcpu_info[0].time;
