Querying battery (or temperature) using ACPI takes quite some
resources, which makes the battery discharge faster. It doesn't make
much sense to have it queried as often either. So, when using ACPI:
1) set battery query period to 10s minimum
2) set temperature query period to 5s minimum
When _startbuf is invoked, it would crash on the second invocation
if creating a mux segment failed. This is because the first attempt
would assign the return value -1 to the global mux variable, and
the second attempt would notice that the global mux was not nil,
and would attempt to use it.
This change only assigns to the global variable if the allocation
of the segment was a success.
While we're here, we should also check the return of the rfork call.
When invoking with dd with an invalid size suffix, we
silently accept the suffix. This can lead to confusion,
because lines like:
dd -bs 1K
dd -bs 1m
will silently copy in 1-byte increments. This has caught
people by surprise. While we're at it, megabytes are
convenient, so let's have them too.
Passwd used to produce a very confusing error
about DES not being enabled whenever the password
was mistyped. This happened because we attempted
to guess what authentication method to use, and
preseneted the error from the wrong one on failure.
This puts the legacy mode behind a flag, so that
we don't even try the old method unless it's
explicitly requested.
This adds the new function pointer PCArch.clockinit(),
which is a timer dependent initialization routine.
It also takes over the job of guesscpuhz(). This way, the
architecture ident code can switch between different
timers (i8253, HPET and XEN timer).
Revert the change, as it causes system lockups on bootup
on some systems with USB OHCI controllers, suspected to be
caused by BIOS/SMM accessing the device as BIOS handover
has not been executed yet.
We might bring that back when the problem has is better
understood.
when loading large binaries such as netsurf, with many
symbols, our hash table fills up with collisions and
loading the symbol table gets very slow. Bumping it up
drops the time to lstk() in acid on netsurf from 4 minutes
to 8 seconds.
Call exits(0) instead of returning from main. Also call sysfatal if
writing of image data fails. Previously, qr(1) would exit with
default non-nil status "main" unconditionally as a result of returning
from main.
/$objtype/include/ape/math.h contained an almost
identical copy of math.h for each architecture.
The only difference between them architectures
was that some had an incorrect version of isinf
defined.
This change picks one of the versions of math.h
with a correct definition, moves it to /sys/include,
and removes the redundant versions.
