The profile utility can set the sprofiling mode
...
- profile --nmi | --rtc sets the profiling mode
- --rtc is default, uses BIOS RTC, cannot profile kernel the presetted
frequency values apply
- --nmi is only available in APIC mode as it uses the NMI watchdog, -f
allows any frequency in Hz
- both modes use compatible data structures

SMP - can boot even if some cpus fail to boot
...
- EBADCPU is returned is scheduler tries to run a process on a CPU
that either does not exist or isn't booted
- this change was originally meant to deal with stupid cpuid
instruction which provides totally useless information about
hyper-threading and MPS which does not deal with ht at all. ACPI
provides correct information. If ht is turned off it looks like some
CPUs failed to boot. Nevertheless this patch may be handy for
testing/benchmarking in the future.

SMP - Process is stopped when VM modifies the page tables
...
- RTS_VMINHIBIT flag is used to stop process while VM is fiddling with
its pagetables
- more generic way of sending synchronous scheduling events among cpus
- do the x-cpu smp sched calls only if the target process is runnable.
If it is not, it cannot be running and it cannot become runnable
this CPU holds the BKL

SMP - Changed prototype of sys_schedule()
...
- sys_schedule can change only selected values, -1 means that the
current value should be kept unchanged. For instance we mostly want
to change the scheduling quantum and priority but we want to keep
the process at the current cpu
- RS can hand off its processes to scheduler
- service can read the destination cpu from system.conf
- RS can pass the information farther

SMP - Scheduler can assign process to a cpu
...
- machine information contains the number of cpus and the bsp id
- a dummy SMP scheduler which keeps all system processes on BSP and
all other process on APs. The scheduler remembers how many processes
are assigned to each CPU and always picks the one with the least
processes for a new process.
