that name as a variable. Use mtx_owned(&Giant) where appropriate
instead.
- Proc locking.
- P_FOO -> PS_FOO.
- Update comments about enable interrupts during trap and why this may be
bad if we trap while holding a spin mutex.
- Don't bother resetting p to curproc in syscall() in case we are the child
returning from fork. The child hasn't returned from fork through syscall
in a while.
- Remove fork_return() as it has been superseded by the MI version.
the alpha mp_machdep.c.
- Proc locking.
- Catch up to the P_FOO -> PS_FOO proc flags changes.
- Stick ap_init()'s prototype with the other prototypes.
- Remove the Xforwardirq IPI.
- Remove unused simplelocks.
- Don't try to psignal() from forward_statclock(), but set the appropriate
signal pending flag in p_sflag instead.
- Add in KTR_SMP tracepoints for various SMP functions. (Brought over
from the alpha port)
- Setup proc0.p_heldmtx, proc0.contested, and curproc earlier so that we
can use mutexes.
- Initialize sched_lock and Giant earlier and enter Giant during init386.
- Use suser(9) instead of checking cr_uid directly.
and is protected by the proc lock. p_sflag is protected by sched_lock
and holds the following flags: PS_INMEM, PS_OWEUPC, PS_PROFIL, PS_SINTR,
PS_TIMEOUT, PS_ALRMPEND, PS_PROFPEND, PS_CVWAITQ, PS_SWAPINREQ, and
PS_SWAPPING.
- p_klist is definitely locked now by the proc lock.
- p_runtime, p_[usi]u are locked by sched_lock.
- Add a new P_KTHREAD flag set for kernel threads created via
kthread_create(9).
- STOPEVENT() only needs the proc lock, it does not need Giant.
- faultin() already checks PS_INMEM, so simplify the check in PHOLD() so
that we only need to grab the proc lock and let faultin() perform the
PS_INMEM check.
- Add a prototype for zpfind().
- Add prototypes for the new fork_exit() and fork_return() MI functions
that manage the fork return path.
- Add a prototype for the MD function userret() so that it can be called
from fork_return().
- Add needed include of <machine/frame.h> in the kernel.
- Use "OPOST | ONLCR" as a c_oflag in the raw mode instead of 0, which should
make debug output mode readable;
- flush input buffer when switching to/from raw mode. This should prevent
leaking raw scancodes into your shell prompt when program called
VGLKeyboardEnd() w/o processing all scancodes in the buffer.
- remove all occurances of FLAG_XXX values and replace with CARD_TYPEP_XXX
- remove sc_flag from isic softc and replace it with sc_cardtyp
remove some left over redundant definitions from isic and i4b_l1.h
remove left over cvs id from i4b cvs repository
an override as a loader settable variable (fxp_iomap). fxp_iomap is
a bitmap of fxp units that should be configured to use PCI I/O space
in stead of PCI Memory space.
