profiling, and various protection checks that cause security holes
and system crashes.
* Changed min/max/bcmp/ffs/strlen to be static inline functions
- included from cpufunc.h in via systm.h. This change
improves performance in many parts of the kernel - up to 5% in the
networking layer alone. Note that this requires systm.h to be included
in any file that uses these functions otherwise it won't be able to
find them during the load.
* Fixed incorrect call to splx() in if_is.c
* Fixed bogus variable assignment to splx() in if_ed.c
* them in cpufunc.h. Modified wait loop in reset to look a little better.
* Added read for talley counters to prevent an infinite loop on old
* 8003E's if they (the counters) overflow.
asic register even if the board isn't a 3c503. This caused old 8003E's not
to work because they ignore IO address bits >10bits and the 3c503 asic is
located at +0x400....the offset was ignored by the 8003E and so the
value was written to one of the NIC registers. The bug was discovered by
Wolfgang Solfrank.
8bit or 16bit operation, and a flag to disable transmitter double buffering.
See the updated "ed.relnotes" file for information about how to set
the flags.
This should be considered the first "production" release. It still
needs a manual page, though.
way of doing things. There still remain several drivers that need to
be updated. Also added a compile-time option to pccons to switch the
control and caps-lock keys (REVERSE_CAPS_CTRL) - added for my personal
sanity.
lpt doesn't work here if the printer is not turned on at boot time (this
has been reported for other systems).
lpt has a weird mapping of the flag bits vs printer numbers and MAKEDEV
does not understand this (printer 0 uses minor numbers 0-0x3f, printer 1
uses minors 0x40-0x7f, etc).
The following (simpler) problems are fixed by the patch.
lpt did not check the minor number on open, so if NLPT1 == 1 and you
try to open printer 1 then random memory above the lpt_sc array is
accessed. I thought I had this problem for minors 1 and 2. However,
it does not actually occur until minor 0x40. Does anyone have lpt64?
lpt had several unnecessary && broken ANSIisms and other sloppy
declarations.
