user to:
- get entries from a file other than "calendar".
- get entries for a different date than today.
- get entries for a whole week in advance, or only one day.
processing of /etc/ld.so.conf in ld.so itself (rather than in /etc/rc):
- added do_conf function and call to it in main to implement internal
processing of /etc/ld.so.conf
- moved maintenance of dir_list to dodir, with an added argument to
dodir to specify whether dir_list should be updated
- added option '-c' to suppress processing of /etc/ld.so.conf
- added option '-S' to suppress processing of std directories (but not
/etc/ld.so.conf)
- modified option -s to suppress processing of _both_ std directories
and /etc/ld.so.conf (i.e., it is equivalent to -cS)--this was done
so that users and scripts that interpret -s as meaning "process
only directories specified on the command line" would not be
startled
From PR #4031. One change was not committed, since it was unnecessary
(option variables are in the BSS, and do not need to be initialized to
0 explicitly).
Plus one change from me:
- getopt() returns -1 when completed, not EOF.
two DMA channels to do e.g. full-duplex. This allows
a way of specifying the second channel in a sane way.
THIS IS TEMPORARY. The drq2 locator will go away when
the locator system has been changed to allow multiple
values per locator.
* hoist code to deal with fragments of a 16-byte chunk outside
main copy loop.
* over 98% of dynamic calls are 2-byte-algnied but not 4-byte-aligned
(due to 14-byte Ether headers). kernel bcopy is poorly tune for this.
Replace bcopy() with inline code tuned to minimize accesses
to DMA buffers, which aren't uncached on mips.
Tested on 5000/240 (3MAXPLUS) and 3000/700 (sandpiper) (mjacob@feral.com)
device memory mapping cacheable/non-cacheable:
- PG_N doesn't exist on the 386.
- pmap_changebit() only deals with managed pages.
Basically, calling it is unnecessary, and never did anything. Pointed
out by Chuck Cranor, and further discussed with Frank van der Linden.
Also, add a comment about why we don't mark pages non-cacheable in
_bus_dmamem_map().
