- cpuclass should be cpu_class
- CPUCLASS_I386 should be CPUCLASS_386
(^^ those only show up if you compile for i386)
- two missing prototypes on new functions
- one missing static
to 20000 through 30000. These numbers are used for local IP port numbers
when an explicit address is not specified.
The values are sysctl modifiable under: net.inet.ip.port_{first|last}_auto
These numbers do not overlap with any known server addresses, without going
above 32768 which are "negative" on some other implementations.
20000 through 30000 is 2.5 times larger than the old range, but some have
suggested even that may not be enough... (gasp!) Setting a low address
of 10000 should be plenty.. :-)
Speed up for vfs_bio -- addition of a routine bqrelse to greatly diminish
overhead for merged cache.
Efficiency improvement for vfs_cluster. It used to do alot of redundant
calls to cluster_rbuild.
Correct the ordering for vrele of .text and release of credentials.
Use the selective tlb update for 486/586/P6.
Numerous fixes to the size of objects allocated for files. Additionally,
fixes in the various pagers.
Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs.
Fixes in the swap pager for exhausted resources. The pageout code
will not as readily thrash.
Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into
page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE),
thereby improving efficiency of several routines.
Eliminate even more unnecessary vm_page_protect operations.
Significantly speed up process forks.
Make vm_object_page_clean more efficient, thereby eliminating the pause
that happens every 30seconds.
Make sequential clustered writes B_ASYNC instead of B_DELWRI even in the
case of filesystems mounted async.
Fix a panic with busy pages when write clustering is done for non-VMIO
buffers.
left to do (e.g. it doesn't yet run on systems with aliased addresses)
but this should work for simple configurations.
I don't plan to enable the rdisc directory in the sbin/ makefile until
I get feedback on this and add the missing features, so please, if you
have routers that perform router discovery, or if your FreeBSD box is
itself a router, give this a try.
Save 112K for SB, 64K for PAS and 64K for MSS.
Since PAS use SB emulation, 176K normally saved for it.
Few minor optimizations added like in Linux driver.
When you start tracker and produce some heavy disk activity,
output interrupts becomes lost and I don't know how to solve it
finally. Newly added code at least allows recovery after timeout.
from args, e.g. cdplay cd0 "play 1 99" if you just want to feed the
CD a command and exit the cdplay utility. Note that if you want to use
post-play commands like `pause' and `resume', you should still use cdplay
interactively.
1) correct MAX_PID according to system definition.
2) replace fprintf(stderr,...)/perror/exit by 4.4 equivalence.
3) make strings enough larger so they can't overflow: MAXHOSTNAMELEN for
host and MAXPATHLEN for filenames.
4) call execl with correct parameters (compress -> gzip).
Fixed BCD declarations. They didn't match their definitions...
libkern.h, bcd.c:
KNFised. `indent' worked 99% perfectly on bcd.c. It worked 99%
_imperfectly_ on subr_prf.c.
2) Use CURSIG(curproc) in PROCESS_ABORTING instead of junk code was there.
3) Reanimate timeout code in DO_SLEEP by setting WK_TIMEOUT flag
which is never set in old code.
4) DO_SLEEP: set aborting flag on interrupting singnals as supposed, not
on signals which do nothing as in old code.
5) Cleanup WAKE_UP macro, WK_WAKEUP not used.
6) Remove wrong typecasts in sleep/wakeup code.
and suiword(). They are no longer referenced in the machine-independent
code (I think fuiword() and suiword() were only used by old versions of
ptrace(), and copyoutstr() by old versions of exec).
Added `const' where appropriate.
Changed u_int to size_t' where appropriate.
Named last arg of copystr() and copyinstr() better.
This random address can be matched (with some probability) with another
sleep addresses from other drivers, which can cause strange sleep/wakeup
sequence. Rewrite this ugly code to do the right thing.
