| | | | | | | | | | register our sub-busses in the reversed order. In the future, we may provide a hint to CAM on how to order the scans for multi-function adapters that also set this flag, but trying to do it the "twin channel" way will lead to a panic. Notes: svn path=/head/; revision=72552

* Implement a unified run queue and adjust priority levels accordingly.Jake Burkholder2001-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - All processes go into the same array of queues, with different scheduling classes using different portions of the array. This allows user processes to have their priorities propogated up into interrupt thread range if need be. - I chose 64 run queues as an arbitrary number that is greater than 32. We used to have 4 separate arrays of 32 queues each, so this may not be optimal. The new run queue code was written with this in mind; changing the number of run queues only requires changing constants in runq.h and adjusting the priority levels. - The new run queue code takes the run queue as a parameter. This is intended to be used to create per-cpu run queues. Implement wrappers for compatibility with the old interface which pass in the global run queue structure. - Group the priority level, user priority, native priority (before propogation) and the scheduling class into a struct priority. - Change any hard coded priority levels that I found to use symbolic constants (TTIPRI and TTOPRI). - Remove the curpriority global variable and use that of curproc. This was used to detect when a process' priority had lowered and it should yield. We now effectively yield on every interrupt. - Activate propogate_priority(). It should now have the desired effect without needing to also propogate the scheduling class. - Temporarily comment out the call to vm_page_zero_idle() in the idle loop. It interfered with propogate_priority() because the idle process needed to do a non-blocking acquire of Giant and then other processes would try to propogate their priority onto it. The idle process should not do anything except idle. vm_page_zero_idle() will return in the form of an idle priority kernel thread which is woken up at apprioriate times by the vm system. - Update struct kinfo_proc to the new priority interface. Deliberately change its size by adjusting the spare fields. It remained the same size, but the layout has changed, so userland processes that use it would parse the data incorrectly. The size constraint should really be changed to an arbitrary version number. Also add a debug.sizeof sysctl node for struct kinfo_proc. Notes: svn path=/head/; revision=72376

* Fix:Gerard Roudier2001-02-111-10/+32
| | | | | | | | | | | | | | | | | | | | - Missing cpu_to_scr() added (endian-ness). Improvement (fix|workaroung??): - Blindly firing a PPR can lead to some messy situations due to various causes or misfeatures, for example: * The 53C1010-[33|66] supports offset 62 in DT mode, but only offset 31 in ST mode. As a result, a PPR(DT, offset 62) responded with PPR(ST, any offset > 31) must be rejected. * A device that doesn't know about PPR should reject it, but may also be confused by this message. When a PPR encounters problems, the driver now patches the goal transfer settings for legacy negotiations to be performed later with the offending target. This give a chance for bad situations to be fixed automagically. Notes: svn path=/head/; revision=72361

Make sure we (for our own benefit) mark req_state_flags with RQSF_GOT_SENSE for Fibre Channel if we got sense data- the !*$)!*$)~*$)*$ Qlogic f/w doesn't do so. Add ISPCTL_SCAN_FABRIC, ISPCTL_SCAN_LOOP, ISPCTL_SEND_LIP, and ISPCTL_GET_POSMAP isp_control functions. Correctly send async notifications upstream for changes in the name server, changes in the port database, and f/w crashes. Correctly set topology when we get a ASYNC_PTPMODE event. Major stuff: Quite massively redo how we handle Loop events- we've now added several intermediate states between LOOP_PDB_RCVD and LOOP_READY. This allows us a lot finer control about how we scan fabric, whether we go further than scanning fabric, how we look at the local loop, and whether we merge entries at the level or not. This is the next to last step for moving managing loop state out of the core module entirely (whereupon loop && fabric events will simply freeze the command queue and a thread will run to figure out what's changed and *it* will re-enable the queu). This fine amount of control also gets us closer to having an external policy engine decide which fabric devices we really want to log into. Notes: svn path=/head/; revision=72346

* aic7xxx.c:Justin T. Gibbs2001-02-105-78/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Style nits. Make sure that our selection hardware is disabled as soon as possible after detecting a busfree and even go so far as to disable the selection hardware in advance of an event that will cause a busfree (ABORT or BUS DEVICE RESET message). The concern is that the selection hardware will select a target for which, after processing the bus free, there will be no commands pending. The sequencer idle loop will re-enable the selection should it still be necessary. In ahc_handle_scsiint(), clear SSTAT0 events several PCI transactions (most notably reads) prior to clearing SCSIINT. The newer chips seem to take a bit of time to see the change which can make the clearing of SCSIINT ineffective. Don't bother panicing at the end of ahc_handle_scsiint(). Getting to the final else just means we lost the race with clearing SCSIINT. In ahc_free(), handle init-level 0. This can happen when we fail the attach for RAID devices. While I'm here, also kill the parent dma tag. In ahc_match_scb(), consider initiator ccbs to be any that are not from the target mode group. This fixes a bug where an external target reset CCB was not getting cleaned up by the reset code. Don't bother freezing a ccb in any of our "abort" routines when the status is set to CAM_REQ_CMP. This can happen for a target reset ccb. aic7xxx.reg: Reserve space for a completion queue. This will be used to enhance performance in the near future. aic7xxx.seq: Remove an optimization for the 7890 autoflush bug that turned out to allow, in rare cases, some data to get lost. Implement a simpler, faster, fix for the PCI_2_1 retry bug that hangs the sequencer on an SCB dma for certain chips. Test against SAVED_SCSIID rather than SELID during target reselections. This is how we always did it in the past, but the code was modified while trying to work around an issue with the 7895. SAVED_SCSIID takes into account twin channel adapters such as the 2742T, whereas SELID does not have the channel bit. This caused invalid selection warnings and other strangeness on these cards. aic7xxx_pci.c Use the correct mask for checking the generic aic7892 entry. Notes: svn path=/head/; revision=72325

| | | | | | | | | | | This mistake seems to have been benign until very recently, probably until msmith's PCI code reshuffle which cleaned up a lot of things. Still, my AIC7770 doesn't work again, but it at least probes the EISA bus now. Notes: svn path=/head/; revision=72228
* Change and clean the mutex lock interface.Bosko Milekic2001-02-0921-151/+151
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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) Notes: svn path=/head/; revision=72200
