Move ivec_dsp from trap.h to scb.h
Add interrupt counting to asc, le, ze, ncr, dz interrupts.
add common support for counting interrupts to cnm_idisp so
it can be done very efficiently.
Add other codes for struct references.
Add softintr framework for IPL_SOFTNET and IPL_SOFTSERIAL.
General cleanup of .s files replacing hardcoded structure offsets with
symbolic ones.
Fix botch on my part and make the IPL_* match reality on VAX.
Redefine spl macro using the symbolic IPL_ instead of being hardcoded.
Move schedsoftnet, schedsoftclock from <machine/cpu.h> to <machine/intr.h>
Add a _setsirr macro for schedsoft*.
Add softintr function and framework.
both uniprocessor and multiprocessor environments. Use the otherwise
unused internal CPU register SSP to store the cpu_info pointer.
The macros curcpu(), curproc, cpu_number() and need_resched() are now the
same in both uniprocessor and multiprocessor environments.
doing a cpu_set_kpc(), just pass the entry point and argument all
the way down the fork path starting with fork1(). In order to
avoid special-casing the normal fork in every cpu_fork(), MI code
passes down child_return() and the child process pointer explicitly.
This fixes a race condition on multiprocessor systems; a CPU could
grab the newly created processes (which has been placed on a run queue)
before cpu_set_kpc() would be performed.
- Change ktrace interface to pass in the current process, rather than
p->p_tracep, since the various ktr* function need curproc anyway.
- Add curproc as a parameter to mi_switch() since all callers had it
handy anyway.
- Add a second proc argument for inferior() since callers all had
curproc handy.
Also, miscellaneous cleanups in ktrace:
- ktrace now always uses file-based, rather than vnode-based I/O
(simplifies, increases type safety); eliminate KTRFLAG_FD & KTRFAC_FD.
Do non-blocking I/O, and yield a finite number of times when receiving
EWOULDBLOCK before giving up.
- move code duplicated between sys_fktrace and sys_ktrace into ktrace_common.
- simplify interface to ktrwrite()
state into global and per-CPU scheduler state:
- Global state: sched_qs (run queues), sched_whichqs (bitmap
of non-empty run queues), sched_slpque (sleep queues).
NOTE: These may collectively move into a struct schedstate
at some point in the future.
- Per-CPU state, struct schedstate_percpu: spc_runtime
(time process on this CPU started running), spc_flags
(replaces struct proc's p_schedflags), and
spc_curpriority (usrpri of processes on this CPU).
- Every platform must now supply a struct cpu_info and
a curcpu() macro. Simplify existing cpu_info declarations
where appropriate.
- All references to per-CPU scheduler state now made through
curcpu(). NOTE: this will likely be adjusted in the future
after further changes to struct proc are made.
Tested on i386 and Alpha. Changes are mostly mechanical, but apologies
in advance if it doesn't compile on a particular platform.
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.
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.
- Set the correct adapter address in RPB for Unibus devices.
- Repair the disk read routines for HP disks. ROM routines do not work
on HP disks, therefore use a small home-written routine.
- Use the RPB for passing boot device info up to kernel, instead of the
old BSD "hack" with an encoded longword (see sys/reboot.h for details)
- Instead of separate drivers for all devices, use the HW-provided ROM
routines as much as possible.
- Add filesystem support for CD9660 also (now when there is space).
- Make everything compile with WARNS=1.
The boot block is now <7K in size and have support for UFS, CD9660 and USTAR.
change these from bp->b_un.b_addr to bp->b_data, as well. This also
allows us more flexibility to experiment with other data buffer types
hung off of struct buf.
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
Ethernet packets so the chances are that if the server was fast enough
this driver would continuously lose one of the fragments. Eventually
causing the kernel load to fail. Add 2 extra for random ARP or other
packets that might be picked up.
