2007-02-02[SCSI] fusion - serialize target resets in mptsas.cEric Moore2-45/+281
Fusion firmware requires target reset following hotplug removal event, with purpose to flush target outstanding request in fw. Current implementation does the target resets from delayed work tasks, that in heavy load conditions, take too long to be invoked, resulting in command time outs This patch will issue target reset immediately from ISR context, and will queue remaining target resets to be issued after the previous one completes. The delayed work tasks are spawned during the target reset completion. Signed-off-by: Eric Moore <[email protected]> Signed-off-by: James Bottomley <[email protected]>

2007-01-06[SCSI] fusion: fibre channel: return DID_ERROR for ↵Eric Moore1-0/+11
MPI_IOCSTATUS_SCSI_IOC_TERMINATED A repost of a patch forwarded by Mikael Reed from 2006-12-20. The fibre channel IOC may kill a request for a variety of reasons, some of which may be recovered by a retry, some of which are unlikely to be recovered. Return DID_ERROR instead of DID_RESET to permit retry of the command, just not an infinite number of them.

2006-10-25[SCSI] mptfc: stall eh handlers if resetting while rport blockedMichael Reed2-6/+87
Thanks to James Smart for the inspiration. Stall error handler if attempting recovery while an rport is blocked. This avoids device offline scenarios due to errors in the error handler. Also verify that VirtDevice is available before issuing scsi command. VirtDevice is removed when fc transport removes a target. See James Smart's patch of 08/17/2006 for greater detail. http://marc.theaimsgroup.com/?l=linux-scsi&m=115583213624803&w=2 Also bump version number per Eric's request.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-3/+2
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t. Signed-Off-By: David Howells <[email protected]> (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)

2006-08-27[SCSI] scsi_transport_sas: remove local_attached flagJames Bottomley1-3/+8
This flag denotes local attachment of the phy. There are two problems with it: 1) It's actually redundant ... you can get the same information simply by seeing whether a host is the phys parent 2) we condition a lot of phy parameters on it on the false assumption that we can only control local phys. I'm wiring up phy resets in the aic94xx now, and it will be able to reset non-local phys as well. I fixed 2) by moving the local check into the reset and stats function of the mptsas, since that seems to be the only HBA that can't (currently) control non-local phys.

2006-08-06[SCSI] mptfc: correct out of order event processingMichael Reed2-54/+34
This patch corrects a problem in mptfc which can result in targets being removed after executing an "lsiutil 99" reset of the fibre channel ports. The last rescan event was being processed before the setup reset work due to an inappropriate optimization in the event processing logic. Every rescan event is now queued for execution and the setup reset work now executes in the proper sequence.

2006-06-30[SCSI] mptsas: eliminate ghost devicesJames Bottomley2-0/+25
One of the current problems the mptsas driver has is that of "ghost" devices (these are devices the firmware reports as existing, but what they actually represent are the parents of a lower device), so for example in my dual expander configuration, three expanders actually show up, two for the real expanders but a third is created because the firmware reports that the lower expander also has another expander connected (which is simply the port going back to the upper expander). The attached patch eliminates all these ghosts by not allocating any devices for them if the SAS address is the SAS address of the parent. Signed-off-by: James Bottomley <[email protected]>
