deleting (and cleaning up) N pages of #ifdefs in machdep.c. While we're
at it, make the cpu type options generate flags, and check them instead of
kernel Makefile defines.
Fixes profiling for non-underscore-prepending toolchains
(elf, e.g., shared libs), and breaks a.out/ecoff toolchains.
May break mips kernel profiling too. Needs more thought, since the
original intent of __mcount vs ___mcount on mips date back to pre-1.0 days.
21164 + 21172 box, with Yet Another Way of doing interrupts. The
interrupt mapping and handling code hasn't been written yet, and none
of this code has been tested. (Checkpoint of work in progress.)
* handle interpreters with nonzero virtual address of entry-point:
subtract p_vaddr from computed entrypoint, as the mips elf exec did.
* Add #ifdef ELF_INTERP_NON_RELOCATABLE/#endif around the code
that tries to choose a `good' address at which to load an interpreter,
if none was set by the emul probe function.
(the address chosen could be improved to avoid fragmenting the
process virtual address space).
* define ELF_INTERP_NON_RELOCATABLE in machine/elf_machdep.h for mips CPUs,
which currently use a GNU-derived ld.so.
ELF_INTERP_NON_RELOCATABLE is not necessary for native NetBSD/alpha ELF
binaries. It may be required for GNU-derived ELF dynamic loaders (Linux/i386?)
- Add reset attribute sequences for bold, underline, and reverse
- Add insert/delete line sequences
- Recognize but ignore G0/G1 character set sequences
Performance:
- Speed up clear_line() when clearing the entire line
Also, some stylistic changes for checking/setting scroll region bounds
and in putc_getpars().
These changes make the ITE work properly with the 1.2 termcap file.
Keep queue of pending sockets in a double linked list. Previously,
a singly linked list was used, giving O(N) insertion/deletion times,
and was a major time consumer for sockets with large pending queues.
The double linked list give O(C) insertion/deletion times with only
a small cost in complexity.
Since a socket can be on, at most, one queue at a time, both so_q and
so_q0 can safely be used as (forward and backward, respectively) queue
pointers.
Submitted my Matt Thomas <matt@3am-software.com>, a long time ago.
(Geez, I've been running with this patch for _months_, and had completely
forgotten about it!)
- The boundary argument to bus_space_alloc() should be a bus_size_t, not
a bus_addr_t.
- The buffer arguments in the "multiple write" methods should have
const qualifiers.
And one from me:
- Make bus_space_barrier() eat up the arguments passed to it so that
the compiler doesn't needlessly whine.
the variable `dumpsize' (used by savecore(8)) and that the CPU specific data
gets dumped first.
Also, squash a typo that prevented the crash dump to be shifted towards the
end of the swap partition. In fact, the entire dumpconf() routine has been
redone, mostly by pasting large chunks from the alpha port.
have an Apple Sound Chip. Make sure that we have configured the device
before allowing accesses to ASC memory. Among other things, this
prevents the 660AV and 840AV from getting a kernel bus error when trying
to beep on the console.
everything before the beginning of the "a" partition on a disk
is read-only except when accessed via RAW_PART. (a problem if
"a" isn't at the front of the disk). pointed out by pk back
in july.
