Do a fairly large internal restructuring to accomodate dual-bus host adapters (e.g., the 1240). Include the new 1080/1240 NVRAM layout reading code. Some moderately significant mailbox changes were necessary also to accomodate a second channel.

Locking is now in the outer framework for isp_init/isp_reset- this allows us to call isp_reset/isp_init internally with impunity. Rename isp_phoenix to isp_restart and make it global. Clean it up a tad. If we get an ASYNC_SYSTEM_ERROR code in isp_intr, call isp_restart and return- the f/w is toasted at this point (usually), so we have to bring things back to a known state. In isp_mboxcmd, when we don't see the HOST_INT bit go clear, try and find out if the isp is trying to tell us something and try again. This may avoid a potential deadlock where the previous mailbox command hasn't been cleared by the ISP. In isp_init don't try and get device parameters if we already have them- this typically doesn't work if we're in the middle of an isp_restart.

Hmm- seriously funny and sad bug: you need to directly establish the clock rate for this board on Alpha/PCI systems. Under x86/PCI, the board f/w will correctly tell you "I'm running at 60Mhz", so the code that preserved that across a board reset (which would drop the chip back to 40Mhz) worked fine. On the 8200, the chip was saying "I'm 40Mhz"- which wasn't true. This turned out to be okay as long as you didn't have any FAST or UltraFast targets- In fact, setting the chip to 40Mhz allowed you to run up to 8Mhz SCSI. Unfortunately you die bigtime on the devices that go faster than that. The fix here is to only use what the chip tells you the clock rate is in the cases you don't really know (sbus is the only case where this could be different, although with 66Mhz PCI coming up, this may change).

A) Attempt to get clock rate from ISP chip prior to bashing it over the head in reset. If none there, try and get from the bus/platform specific code. If a nonzero value for either, set the clock rate. This is why the PCI card versions weren't working- they need to be set at 60MHZ, rather than the default 40MHZ (which worked fine for the internal ISP chips on the Alpha 8X00). B) If a isp_poll returns failure (command never completed) to the caller and no error is set in the xs struct, set XS_SELTIMEOUT. And then call... C) Added isp_lostcmd function to try and ask the ISP chip about it's current state as well as the state of commands for a particular target/lun. This is going along to try and figure out why the very first command to the ISP always seems to get swallowed up.

Locking is now in the outer framework for isp_init/isp_reset- this allows us to call isp_reset/isp_init internally with impunity. Rename isp_phoenix to isp_restart and make it global. Clean it up a tad. If we get an ASYNC_SYSTEM_ERROR code in isp_intr, call isp_restart and return- the f/w is toasted at this point (usually), so we have to bring things back to a known state. In isp_mboxcmd, when we don't see the HOST_INT bit go clear, try and find out if the isp is trying to tell us something and try again. This may avoid a potential deadlock where the previous mailbox command hasn't been cleared by the ISP. In isp_init don't try and get device parameters if we already have them- this typically doesn't work if we're in the middle of an isp_restart.

Several changes, including some stub fibre target mode stuff. Establish a slightly different fibre startup (print ALPA now too). Change the way that return values from dma setup is done. Make debug messages out of some queue overflow situations. Turn PORT LOGGED OUT into Selection Timeout equivlaent. On isp_restart actions don't blow off the commands with HBA_BOTCH (XS_DRIVER_STUFFUP) - set them with HBA_BUSRESET (which is defined as XS_DRIVER_STUFFUP until someone decides whether the suggested change to the midlayer NetBSD is worthy of inclusion).

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Locking is now in the outer framework for isp_init/isp_reset- this allows us to call isp_reset/isp_init internally with impunity. Rename isp_phoenix to isp_restart and make it global. Clean it up a tad. If we get an ASYNC_SYSTEM_ERROR code in isp_intr, call isp_restart and return- the f/w is toasted at this point (usually), so we have to bring things back to a known state. In isp_mboxcmd, when we don't see the HOST_INT bit go clear, try and find out if the isp is trying to tell us something and try again. This may avoid a potential deadlock where the previous mailbox command hasn't been cleared by the ISP. In isp_init don't try and get device parameters if we already have them- this typically doesn't work if we're in the middle of an isp_restart.

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

/*

Locking is now in the outer framework for isp_init/isp_reset- this allows us to call isp_reset/isp_init internally with impunity. Rename isp_phoenix to isp_restart and make it global. Clean it up a tad. If we get an ASYNC_SYSTEM_ERROR code in isp_intr, call isp_restart and return- the f/w is toasted at this point (usually), so we have to bring things back to a known state. In isp_mboxcmd, when we don't see the HOST_INT bit go clear, try and find out if the isp is trying to tell us something and try again. This may avoid a potential deadlock where the previous mailbox command hasn't been cleared by the ISP. In isp_init don't try and get device parameters if we already have them- this typically doesn't work if we're in the middle of an isp_restart.

BUS resets not done in isp_init anymore- relegated to OS specific outer layers. Fix a buglet where you can get in a loop for a NULL xs in the completion list in isp_intr.

On isp_restart actions don't blow off the commands with HBA_BOTCH (XS_DRIVER_STUFFUP) - set them with HBA_BUSRESET (which is defined as XS_DRIVER_STUFFUP until someone decides whether the suggested change to the midlayer NetBSD is worthy of inclusion).

Locking is now in the outer framework for isp_init/isp_reset- this allows us to call isp_reset/isp_init internally with impunity. Rename isp_phoenix to isp_restart and make it global. Clean it up a tad. If we get an ASYNC_SYSTEM_ERROR code in isp_intr, call isp_restart and return- the f/w is toasted at this point (usually), so we have to bring things back to a known state. In isp_mboxcmd, when we don't see the HOST_INT bit go clear, try and find out if the isp is trying to tell us something and try again. This may avoid a potential deadlock where the previous mailbox command hasn't been cleared by the ISP. In isp_init don't try and get device parameters if we already have them- this typically doesn't work if we're in the middle of an isp_restart.

If a nonzero value for either, set the clock rate. This is why the PCI card versions weren't working- they need to be set at 60MHZ, rather than the default 40MHZ (which worked fine for the internal ISP chips on the Alpha 8X00).

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.

Make firmware revision a triple. Clean up some FC init stuff for board versions with no BIOS. Separate mailbox interrupts from IOCB interrupts. Read OUTMAILBOX5 while RISC_INT is active- not after you clear it (potential race condition). Clear out older broken BIG_ENDIAN goop. Don't negotiate narrow/async for LVD busses at startup if already in LVD mode. Note usage of presumptive 1040C revision. For all the LIP, PDB Changed, Loop UP/DOWN async events, mark fw state as unknown as well as marking the need to do a getpdb on targets- after a LIP for certain the f/w has to do PRLI/PLOGI for all targets again and marking f/w state as unknown gives us a fighting chance to (start to) hold up for that to complete.
