[Xen-devel] [PATCH][HVM] fix multiplication overflow in hvm/pmtimer.c
Hi, Too many ACPI events (SCI) are raised on hvm because of multiplication overflow. FREQUENCE_PMTIMER=3579545 (1000000000ULL << 32) / FREQUENCE_PMTIMER = 0xae9a7b1663a pmt_cycles_until_flip =~ 0x80000000 0xae9a7b1663a*0x80000000 = overflow!!!
