yamt dbb4e0d985 - move return values info into RETURN VALUES section. 
- note that O_SHLOCK and O_EXLOCK are not portable.
from OpenBSD.

briggs 126f6cf9bc Add a new option EVBARM_BOARDTYPE to differentiate between different 
evbarm ports.  Inline _splraise/_spllower/splx for i80321 and iq80310
for more performance.

chris 725f3ca1a7 correct comment, it's r0, not a0. 2002-08-17 01:23:36 +00:00
chris d8ac0fb3aa pull in ffs.S from libc for arm. 
The main benefit is that ffs always runs in constant time.

briggs d86c947b8c Inline bus_dma_inrange() and bus_dmamap_sync_*(). 2002-08-17 01:15:15 +00:00
thorpej 50fe583069 Must ... micro ... optimize! 
* Save an instruction in the transition from idle to have-process-to-
  switch-to, and eliminate two instructions that cause datadep-stalls
  on StrongARM And XScale (one in each idle block).
* Rearrange some other instructions to avoid datadep-stalls on StrongARM
  and XScale.
* Since cpu_do_powersave == 0 is by far the common case, avoid a
  pipeline flush by reordering the two idle blocks.

chris 1334ab7d1e following Jason's change to _xscale, convert bpl's to bhi's, saves looping more than needed in some cases. 2002-08-17 01:02:38 +00:00

bjh21 72f31d9112 If we're treating the MEMC as a TLB, there's no need to completely reload 
it in pmap_activate().  Instead, let's leave it empty and let pages be
faulted into it on demand.  This improves the context switch latency
somewhat, at least for small processes.

itojun 4005a5250f set h_errno properly if internal string manipulation fails. 2002-08-16 21:54:00 +00:00
mjacob bb6cb67b54 Further fix problems with 23XX ISR handling and correctly initialize the 
23XX to use ZIO in preference to fast posting.

bjh21 4d7743ff17 According to Chuck Silvers, pmap_copy_page() and pmap_zero_page() don't 
need to mess with the referenced and modified flags, since they're only
called when a page is being initialised, and is about to have them cleared.
Make this so.

itojun 2abe377059 defend against malicious line in ut_line, which could cause unwanted 
writes to anything under /dev.  revoke setuid/gid privs earlier.

martin 39acbf03ed Avoid exit(0) to play more nicely with rc_fast_and_loose.

petrov 7de59e9a76 Add tty for sab. 2002-08-16 17:56:56 +00:00
thorpej ebff575bc3 * Add a new machdep.powersave sysctl, which controls the use of 
the CPU's "sleep" function in the idle loop.
* Default all CPUs to not use powersave, except for the PDA processors
  (SA11x0 and PXA2x0).

This significantly reduces inteterrupt latency in high-performance
applications (and was good to squeeze another ~10% out of an XScale
IOP on a Gig-E benchmark).

fredette a3961f4a15 This cleans up interrupts with respect to GSC bus chips and the devices 
they contain.  IRQ information for these has been removed from the
kernel configuration file.  GSC bus chips now choose an available CPU
IRQ for themselves, and know IRQ information for all of the devices
they may contain.  Minor autoconfiguration changes support this.

Renamed the old-style vmstat interrupt counters to say "ipl" and not
"irq", since they've been disconnected from irq numbers.  Also provide
a function to allocate an irq bit from an interrupt register, and a
function to report the next ipl bit that will be allocated.

jdolecek d23ad48af9 use 'pid_t' for pipe_pgid, rather that 'gid_t' 
this fixes the code in pipeselwakeup() to properly send signal to process group

Problem found by Anders Magnusson, using gcc 3.2 with pdp-10 target.
