i/o is done. Instead, pass an opaque cookie which is then passed to a
new routine, coredump_write, which does the actual i/o. This allows the
method of doing i/o to change without affecting any future MD code.
Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that
core_elf64.c uses core_elf32.c) and eliminate that code duplication.
cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill
the core structure and a second to actually write md parts of the coredump.
All i/o is nolonger random access and is suitable for shipping over a stream.
the information there.
TODO:
1. since timer stuff gets called from an interrupt context, we could
preallocate ksiginfo_t's from the pool, so we don't need a kmem
pool.
2. probably the sa signal delivery syscall can be changed to take
a ksiginfo_t so we can use only one pool.
3. maybe when we add realtime signal support, add a resource limit
on the number of ksiginfo_t's a process can allocate.
be inserted into ktrace records. The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.
Bump the kernel rev up to 1.6V
out the writing of an lwp's registers to a separate function. XXX Although
not really the correct way to do this, make the thread that caused the
coredump has it's register set written first so GDB is happy. (this is a
bridge until TRT is done).
