from db_stack_trace_cmd() to db_stack_trace_print(),
and add an additional argument, a function pointer for an
output routine (i.e. printf() or db_printf()).
Add db_stack_trace_cmd() in db_command.[ch], calling
db_stack_trace_print() with db_printf() as the printer.
Move count==-1 special handling from db_stack_trace_print() [nee
db_stack_trace_cmd()] to db_stack_trace_cmd() [nascent here].
Again, I'm unable to test compilation on all affected platforms,
so advance apologies for potential brokenness.
kvm_getproc2() -> sysctl(KERN_PROC2)
kvm_getargv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ARGV)
kvm_getenvv2() -> sysctl(KERN_PROC_ARGS, KERN_PROC_ENV)
Add new KVM_NO_FILES flag to kvm_open*() - set up enough state to
use the above calls without having to open any kernel files.
XXX: kvm_getprocs.3 and kvm_open.3 to be updated soon.
errors from ps(1) and some other kernel grovellers, and return some
data that has previously only been accessable with /dev/kmem read
access. The sysctls are:
+ KERN_PROC2 - return an array of fixed sized "struct kinfo_proc2"
structures that contain most of the useful user-level data in
"struct proc" and "struct user". The sysctl also takes the size of
each element, so that if "struct kinfo_proc2" grows over time old
binaries will still be able to request a fixed size amount of data.
+ KERN_PROC_ARGS - return the argv or envv for a particular process id.
envv will only be returned if the process has the same user id as the
requestor or if the requestor is root.
+ KERN_FSCALE - return the current kernel fixpt scale factor.
+ KERN_CCPU - return the scheduler exponential decay value.
+ KERN_CP_TIME - return cpu time state counters.
With input and suggestions from many people on tech-kern.
which indicates that the process is actually running on a
processor. Test against SONPROC as appropriate rather than
combinations of SRUN and curproc. Update all context switch code
to properly set SONPROC when the process becomes the current
process on the CPU.
Lots of the work was done by Adam Ciarcinsky.
Currently, this only supports CyberPPC boards by Phase 5. Blizzard PPC

The kernel is useless but for demonstrating that it starts... especially
interupts, and most of MMU support, is not in yet. Builtin console works,
however, and you can look at the kernel startup messages.
pointer indicating how to print the symbol. This allows db_printsym()
to called in places where db_printf() is not an appropriate output
function.
While straightforward, apologies in advance if I've introduced any minor
syntax errors; I was unable to test compilation this on all the affected
platforms.

This is because ite_filter() is called before init(8) opens the console.
- Add 16 bytes to the stack on entry to _mcount so we don't
overflow it.
- Use inline interrupt {dis,en}abling instead of calling
profiled function in locore.
