Happy to have now a clone of our server board (supermicro H8SGL-F) for a
workstation, naturally with latest optéron:
$ psrinfo -v -p 1
The physical processor has 12 virtual processors (0-11)
x86 (AuthenticAMD 600F20 family 21 model 2 step 0 clock 2300 MHz)
AMD Opteron(tm) Processor 6338P
It is a 12 core processor and I notice the following new message:
drmach_acpi: [ID 779328 kern.warning] WARNING: drmach_init: number of logical
CPUs (12) in physical processor is not power of 2.
not [yet] too familiar with dynamic reconfigure issues, is this
[already] an issue or a rather a noop?
static int
drmach_init(void)
{
DRMACH_HANDLE hdl;
drmachid_t id;
uint_t bnum;
if (MAX_BOARDS > SHRT_MAX) {
cmn_err(CE_WARN, "!drmach_init: system has too many (%d) "
"hotplug capable boards.", MAX_BOARDS);
return (ENXIO);
} else if (MAX_CMP_UNITS_PER_BOARD > 1) {
cmn_err(CE_WARN, "!drmach_init: DR doesn't support multiple "
"(%d) physical processors on one board.",
MAX_CMP_UNITS_PER_BOARD);
return (ENXIO);
} else if (MAX_CORES_PER_CMP & (MAX_CORES_PER_CMP - 1)) {
cmn_err(CE_WARN, "!drmach_init: number of logical CPUs (%d) in "
"physical processor is not power of 2.",
MAX_CORES_PER_CMP);
return (ENXIO);
} else if (MAX_CPU_UNITS_PER_BOARD > DEVSET_CPU_NUMBER ||
MAX_MEM_UNITS_PER_BOARD > DEVSET_MEM_NUMBER ||
MAX_IO_UNITS_PER_BOARD > DEVSET_IO_NUMBER) {
cmn_err(CE_WARN, "!drmach_init: system has more CPU/memory/IO "
"units than the DR driver can handle.");
return (ENXIO);
}
rw_init(&drmach_cpr_rwlock, NULL, RW_DEFAULT, NULL);
drmach_cpr_cid = callb_add(drmach_cpr_callb, NULL,
CB_CL_CPR_PM, "drmach");
It appears to simply turn off dynamic reconfiguration.
Am I missing anything?
