joerg d84e0831f3 Revert last commit which added externs that never get defined anywhere. 
At least lapic_get_timecount conflicts with the newly added lapic TC.

elad 5187640465 Don't make root an exception when enforcing rlimits. 
Suggested by yamt@ months ago; okay christos@.

joerg e5784d23f1 Add a CPU local timer based on the LAPIC. This is consistently faster 
than TSC, but doesn't suffer from SpeedStep as TSC does.

The default quality is higher than HPET for UP, but -100 for
MULTIPROCESSOR as it needs CPU local state which doesn't exist yet.

ad 27f20ecf58 Soft interrupts can now take proclist_lock, so there is no need to 
double-lock alllwp or allproc.

riz 3f811928da Cast sf->f_bsize to int to force signed division. Fixes this test 
on amd64, and probably other 64-bit platforms.

ad 9027344d32 For the slow path soft interrupts, arrange to have the priority of a 
borrowed user LWP raised into the 'kernel RT' range if the LWP sleeps
(which is unlikely).

tsutsui bdce6fcc66 Raise hp300_ipl2psl[IPL_VM] in intr_computeipl() accordingly. 
(maybe mac68k has the same problem)

XXX: maybe we could use a possible highest device ipl (5 on hp300?) for IPL_VM.
 2007-12-03 16:18:47 +00:00
ad 4b293a84e1 Interrupt handling changes, in discussion since February: 
- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.

pooka af3b65635e Allow EVFILT_WRITE kqfilters to be registered and map them to 
seltrue_filtops.

pooka 01f5a6d143 Some boys take a beautiful seltrue_filtops and hide her away from 
the rest of the world - but let's not.

rafal 7b4886ba60 Clear interrupts as they are established, rearrange interrupt-mapping code 
to make sure PCI slot 0 interrupt doesn't accidentally match the (unused)
PCI error interrupt.

Fixes kern/25462 at least on my Netra T1 ac200.
From OpenBSD; ok martin@

isaki 5b22b72692 white space fix. 2007-12-03 09:54:24 +00:00
isaki 48e1704028 Use standard error code (EIO) instead of standalone error code 
(ESHORT).  Because loadfile_*() is used with or without
_STANDALONE, therefore, don't use error code in "saerrno.h".
Pointed out by and discussed with he@.

christos 9e2c6405b0 kill a diagnostic for now. 2007-12-03 02:20:24 +00:00
christos 33cb8be1db - add an elf aux vector entry for implementing $ORIGIN. 
- the code to convert from a vnode to a path is commented out now until
  a better solution is implemented. Only absolute paths work for now
  (which is most of the cases).

rumble f06a64e97b Fix two minor bugs: 
1) If ODCM is disabled (ODCM_ENABLE not set), clockmod_getstate() should
    return the maximum level (7), not the lowest (0), as the levels are
    defined as duty cycles where the highest implies no ODCM. Now sysctl
    machdep.clockmod.current doesn't lie upon init.

 2) Make the sysctl handler ensure that no disabled levels are permitted.
    Previously, a level disabled due to errata could be passed to
    clockmod_setstate(), which would search through the state array,
    skipping the unusable value. Consequently our index would be out of
    range and badness could ensue.

Okay'd by xtraeme@.

dsl cd39f2272a Improve the likelyhood of the 'oosyscall' code (ie that for system call entry 
via a call gate for i386 netbsd 1.0 and ibcs2) doing the right thing.
Untested because I've failed to get an a.out netbsd 1.0 binary to load.
