I like it better because I get to see the name of the device as it appears
in the DSDT, which sometimes makes sense and that way it's easier to locate
the relevant code when debugging.
E.g.:
PIC (PNP0000) [AT Interrupt Controller] at acpipcib0 not configured
DMAD (PNP0200) [AT DMA Controller] at acpipcib0 not configured
attimer0 at acpipcib0 (TMR, PNP0100): AT Timer
RTC0 (PNP0B00) [AT Real-Time Clock] at acpipcib0 not configured
pckbc0 at acpipcib0 (PS2K, PNP0303): kbd port
acpibat0 at acpi0 (BAT0, PNP0C0A-0): ACPI Battery (Control Method)
- mark (DIS)CHARGERATE as invalid when (DIS)CHARGING so that envstat
doesn't print some weird stats where the system appears to be doing
both
- handle the case when it's doing neither by marking *RATE as invalid
and setting CHARGING to OFF (because we're not charging, even though
we're not discharging)
- fix print_stats to print correct values in those cases, and a real
percentage (i.e., computed against LFCCAPACITY)
of pending atexit handlers before the structure is reused. This prevents
__cxa_finalize from going into an infinite loop when an atexit handler
register a new atexit handler as in:
#include <stdlib.h>
void two(void) {
}
void one(void) {
atexit(two);
}
int main(void) {
atexit(one);
return 0;
}
hint pointer, but do so in a way that remains compatible with older
pthread libraries. This can be used to wake another thread before the
calling thread goes asleep, saving at least one syscall + involuntary
context switch. This turns out to be a fairly large win on the condvar
benchmarks that I have tried.
1 microsecond into the future, the thread could enter an untimed sleep.
- Change the signature of _lwp_park() to accept an lwpid_t and second
hint pointer, but do so in a way that remains compatible with older
pthread libraries. This can be used to wake another thread before the
calling thread goes asleep, saving at least one syscall + involuntary
context switch. This turns out to be a fairly large win on the condvar
benchmarks that I have tried.
- Mark some more syscalls MP safe.
