| | | | | | | Some things needed bits of <i386/include/lock.h> - cy.c now has its own (only) copy of the COM_(UN)LOCK() macros, and IMASK_(UN)LOCK() has been moved to <i386/include/apic.h> (AKA <machine/apic.h>). Reviewed by: jhb

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mtx_enter(lock, type) becomes: mtx_lock(lock) for sleep locks (MTX_DEF-initialized locks) mtx_lock_spin(lock) for spin locks (MTX_SPIN-initialized) similarily, for releasing a lock, we now have: mtx_unlock(lock) for MTX_DEF and mtx_unlock_spin(lock) for MTX_SPIN. We change the caller interface for the two different types of locks because the semantics are entirely different for each case, and this makes it explicitly clear and, at the same time, it rids us of the extra `type' argument. The enter->lock and exit->unlock change has been made with the idea that we're "locking data" and not "entering locked code" in mind. Further, remove all additional "flags" previously passed to the lock acquire/release routines with the exception of two: MTX_QUIET and MTX_NOSWITCH The functionality of these flags is preserved and they can be passed to the lock/unlock routines by calling the corresponding wrappers: mtx_{lock, unlock}_flags(lock, flag(s)) and mtx_{lock, unlock}_spin_flags(lock, flag(s)) for MTX_DEF and MTX_SPIN locks, respectively. Re-inline some lock acq/rel code; in the sleep lock case, we only inline the _obtain_lock()s in order to ensure that the inlined code fits into a cache line. In the spin lock case, we inline recursion and actually only perform a function call if we need to spin. This change has been made with the idea that we generally tend to avoid spin locks and that also the spin locks that we do have and are heavily used (i.e. sched_lock) do recurse, and therefore in an effort to reduce function call overhead for some architectures (such as alpha), we inline recursion for this case. Create a new malloc type for the witness code and retire from using the M_DEV type. The new type is called M_WITNESS and is only declared if WITNESS is enabled. Begin cleaning up some machdep/mutex.h code - specifically updated the "optimized" inlined code in alpha/mutex.h and wrote MTX_LOCK_SPIN and MTX_UNLOCK_SPIN asm macros for the i386/mutex.h as we presently need those. Finally, caught up to the interface changes in all sys code. Contributors: jake, jhb, jasone (in no particular order)

* - Overhaul the software interrupt code to use interrupt threads for eachjhb2000-10-251-11/+15
| | | | | | | | | | | | | | | | | | | type of software interrupt. Roughly, what used to be a bit in spending now maps to a swi thread. Each thread can have multiple handlers, just like a hardware interrupt thread. - Instead of using a bitmask of pending interrupts, we schedule the specific software interrupt thread to run, so spending, NSWI, and the shandlers array are no longer needed. We can now have an arbitrary number of software interrupt threads. When you register a software interrupt thread via sinthand_add(), you get back a struct intrhand that you pass to sched_swi() when you wish to schedule your swi thread to run. - Convert the name of 'struct intrec' to 'struct intrhand' as it is a bit more intuitive. Also, prefix all the members of struct intrhand with 'ih_'. - Make swi_net() a MI function since there is now no point in it being MD. Submitted by: cp

* Fix crashes on card eject for pccard modems. We check for NULL whenimp2000-03-111-12/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | we get the com address. If so, we go ahead and return. Bruce thinks there's a bug in the pccard layer that it terminates devices with extreme prejustice rather than letting them deside for themselves when to terminate (and he's likely right). This fix doesn't change that, but instead works around it by checking for NULL pointers at more places than before. The detach routine still calls functions at interrupt level that aren't reentrant. In theory this could cause a problem, but none showed up in practice. Future versions should correct this problem, likely by making the detach process a thread/process at the pccard level. NEWCARD will do this, and the current pccard layer should likely be modified to that as well, should it live long enough. A few style nits of the same form that were in my original patch sent off to bde were also fixed as part of this process. Mostly use of !ptr and return ENOPARENS. This should prevent a crash on suspend with an active ppp link as well, but that wasn't tested. Reviewed by: bde Approved by: jkh
