* Removed TIOCMODG and TIOCMODS. They were superseded by TIOCMGET andbde2004-02-041-13/+24
| | | | | | | | | | | | | TIOCMSET before FreeBSD existed and have never been implemented by any FreeBSD serial driver (not even as aliases). Moved the TIOCM bit definitions to be with TIOCMGET. Added more comments gaps between ioctl numbers. There are now a large number of conflicts with ppp, slip, tap and tun ioctls (especially ppp ones) from closing gaps that weren't there. This mainly breaks decoding of ioctl numbers in kdump, but there are some serious conflicts where the interpretation of a tty ioctl depends on the line discipline.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | aic79xx.seq: Convert the COMPLETE_DMA_SCB list to an "stailq". This allows us to safely keep the SCB that is currently being DMA'ed back the host on the head of the list while processing completions off of the bus. The newly completed SCBs are appended to the tail of the queue. In the past, we just dequeued the SCB that was in flight from the list, but this could result in a lost completion should the host perform certain types of error recovery that must cancel all in-flight SCB DMA operations. Switch from using a 16bit completion entry, holding just the tag and the completion valid bit, to a 64bit completion entry that also contains a "status packet valid" indicator. This solves two problems: o The SCB DMA engine on at least Rev B. silicon does not properly deal with a PCI disconnect that occurs at a non-64bit aligned offset in the chips "source buffer". When the transfer is resumed, the DMA engine continues at the correct offset, but may wrap to the head of the buffer causing duplicate completions to be reported to the host. By using a completion buffer in host memory that is 64bit aligned and using 64bit completion entries, such disconnects should only occur at aligned addresses. This assumes that the host bridge will only disconnect on cache-line boundaries and that cache-lines are multpiles of 64bits. o By embedding the status information in the completion entry we can avoid an extra memory reference to the HSCB for commands that complete without error. Use the comparison of a "host freeze count" and a "sequencer freeze count" to allow the host to process most SCBs that complete with non-zero status without having to clear critical sections. Instead the host can just pause the sequencer, performs any necessary cleanup in the waiting for selection list, increments its freeze count on the controller, and unpauses. This is only possible because the sequencer defers completions of SCBs with bad status until after all pending selections have completed. The sequencer then avoids referencing any data structures the host may touch during completion of the SCB until the freeze counts match. aic79xx.c: Change the strategy for allocating our sentinal HSCB for the QINFIFO. In the past, this allocation was tacked onto the QOUTFIFO allocation. Now that the qoutfifo has grown to accomodate larger completion entries, the old approach will result in a 64byte allocation that costs an extra page of coherent memory. We now do this extra allocation via ahd_alloc_scbs() where the "unused space" can be used to allocate "normal" HSCBs. In our packetized busfree handler, use the ENSELO bit to differentiate between packetized and non-packetized unexpected busfree events that occur just after selection, but before the sequencer has had the oportunity to service the selection. When cleaning out the waiting for selection list, use the SCSI mode instead of the command channel mode. The SCB pointer in the command channel mode may be referenced by the SCB dma engine even while the sequencer is paused, whereas the SCSI mode SCB pointer is only accessed by the sequencer. Print the "complete on qfreeze" sequencer SCB completion list in ahd_dump_card_state(). This list holds all SCB completions that are deferred until a pending select-out qfreeze event has taken effect. aic79xx.h: Add definitions and structures to handle the new SCB completion scheme. Add a controller flag that indicates if the controller is in HostRAID mode. aic79xx.reg: Remove macros used for toggling from one data fifo mode to the other. They have not been in use for some time. Add scratch ram fields for our new qfreeze count scheme, converting the complete dma list into an "stailq", and providing for the "complete on qfreeze" SCB completion list. Some other fields were moved to retain proper field alignment (alignment >= field size in bytes). aic79xx.seq: Add code to our idle loop to: o Process deferred completions once a qfreeze event has taken full effect. o Thaw the queue once the sequencer and host qfreeze counts match. Generate 64bit completion entries passing the SCB_SGPTR field as the "good status" indicator. The first bit in this field is only set if we have a valid status packet to send to the host. Convert the COMPLETE_DMA_SCB list to an "stailq". When using "setjmp" to register an idle loop handler, do not combine the "ret" with the block move to pop the stack address in the same instruction. At least on the A, this results in a return to the setjmp caller, not to the new address at the top of the stack. Since we want the latter (we want the newly registered handler to only be invoked from the idle loop), we must use a separate ret instruction. Add a few missing critical sections. Close a race condition that can occur on Rev A. silicon. If both FIFOs happen to be allocated before the sequencer has a chance to service the FIFO that was allocated first, we must take special care to service the FIFO that is not active on the SCSI bus first. This guarantees that a FIFO will be freed to handle any snapshot requests for the FIFO that is still on the bus. Chosing the incorrect FIFO will result in deadlock. Update comments. aic79xx_inline.h Correct the offset calculation for the syncing of our qoutfifo. Update ahd_check_cmdcmpltqueues() for the larger completion entries. aic79xx_pci.c: Attach to HostRAID controllers by default. In the future I may add a sysctl to modify the behavior, but since FreeBSD does not have any HostRAID drivers, failing to attach just results in more email and bug reports for the author.

* Remove pmap_pvo_allocf zone alloc function. It was a way ofgrehan2004-02-043-81/+12
| | | | | | | | | | | | using the direct-mapping of physmem to force PTE data structures to be physically addressable so the interrupt-time real-mode DSI trap handler could perform PTE spills. However, the memory may have been > 256Mb, which would have caused a BAT spill and double-interrupt. The new trap code no longer handles PTE spills, so the requirement that these pages be direct-mapped no longer applies. The irony is UMA_MD_SMALL_ALLOC will return direct mappings for these structs :-)
* Major overhaul of common trap codegrehan2004-02-042-1616/+710
| | | | | | | | | | | | | | | | | | | | | | | | | - remove unused 601 and tlb exception code - remove interrupt-time PTE spill code. The pmap code will now take care of pinning kernel PTEs, and there are no longer issues about physical mapping of PTE data structures - All segment registers are switched on kernel entry/exit, allowing the kernel to have more virtual space and for user virtual space to extend to 4G. - The temporary register save area has been shifted from unused exception vector space to the per-cpu data area. This allows interrupts to be delivered to multiple CPUs - ISI traps no longer spill to BAT tables. It is assumed that all of kernel instruction memory is pinned. - shift from 'ldmw/stmw' instructions to individual register loads/stores when saving context. All PPC manuals indicate this should be much faster. - use '%r' for register names throughout. TODO: need to test if DSI traps were the result of kernel stack guard-page hits. Reworked from: NetBSD

| | | | | | | | | | | Since we have a worker thread now, we can actually do the allocation asynchronously in that thread's context. Also, we need to return a status value: if we're unable to queue up the async allocation, we return NDIS_STATUS_FAILURE, otherwise we return NDIS_STATUS_PENDING to indicate the allocation has been queued and will occur later. This replaces the kludge where we just invoked the callback routine right away in the current context.

* Add the kernel side of network interface renaming support.brooks2004-02-043-23/+64
| | | | | | | | | | | | | | | The basic process is to send a routing socket announcement that the interface has departed, change if_xname, update the sockaddr_dl associated with the interface, and announce the arrival of the interface on the routing socket.
