2006-10-25[SCSI] qla2xxx: Correct QUEUE_FULL handling.Andrew Vasquez
- Drop queue-depths across all luns for a given fcport during TASK_SET_FULL statuses. - Ramp-up I/Os after throttling. - Consolidate completion-status handling of CS_QUEUE_FULL with CS_COMPLETE as ISP24xx firmware no longer reports CS_QUEUE_FULL.

2006-10-25[SCSI] qla2xxx: Workaround D3 power-management issues.Andrew Vasquez
Early ISP2432 parts have a known hardware issue when coming out of a D3 hot state. This issue can result in a hung PCIe link. Recent firmwares contain a workaround whereby the stop-firmware mailbox command prevents the ISP from entering the D3 hot state. In order to ensure that the workaround succeeded the driver must verify that the stop-firmware mailbox command completes successfully. In the event of a failure, the driver attempts a shutdown-retry after resetting the ISP and re-executing firmware.

2006-10-05[PATCH] fix qla{2,4} build errorFrederik Deweerdt
commit 0181944fe647cae18d545ac1167df3d15d393701 adds a 'extended_error_logging' global variable to qla2xxx which is defined by qla4xxx too. Trying to build both drivers results in the following error: LD drivers/scsi/built-in.o drivers/scsi/qla4xxx/built-in.o: In function `qla4xxx_slave_configure': drivers/scsi/qla4xxx/ql4_os.c:1433: multiple definition of `extended_error_logging' drivers/scsi/qla2xxx/built-in.o:drivers/scsi/qla2xxx/qla_os.c:2166: first defined here make[2]: *** [drivers/scsi/built-in.o] Error 1 make[1]: *** [drivers/scsi] Error 2 make: *** [drivers] Error 2 The following patch simply adds a qla2_ (qla4_ respectively) prefix to the variable name.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.

2006-10-03[SCSI] qla2xxx: Add iIDMA support.Andrew Vasquez
iIDMA (Intelligent Interleaved Direct Memory Access) allows for the HBA hardware to send FC frames at the rate at which they can be received by a target device. By taking advantage of the higher link rate, the HBA can maximize bandwidth utilization in a heterogeneous multi-speed SAN. Within a fabric topology, port speed detection is done via a Name Server command (GFPN_ID) followed by a Fabric Management command (GPSC). In an FCAL/N2N topology, port speed is based on the HBA link-rate. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

after relogin. A target can LOGO an initiator at any time (i.e. during I/O, due to a controller hicup, or as a simple authentication mechanism after an initial CDB command), when this occurs, the driver attempts to relogin (PLOGI) to the device via the DPC thread. Add code to make the appropriate upcall to the FC transport layer (fc_remote_port_add()) upon successful completion of the PLOGI.

2006-01-26[SCSI] qla2xxx: Correct synchronization issues during rport addition/deletion.andrew.vasquez@qlogic.com
The driver can typically detect port-loss during an interrupt context (i.e. via interrogation of a status IOCB's completion status [CS_PORT_LOGGED_OUT]. Due to the calling requirements of the fc_rport APIs, the driver would defer removal of the device to the default workqueue. If the work-item was preceded by an event which caused the port to obtain visibility (relogin successful, target re-logged into the topology), deferred removal could inadvertently drop the rport. The code also no longer defers removal via the default workqueue, instead opting for use of the driver's own DPC thread.

2005-10-28[SCSI] qla2xxx: Add support to dynamically enable/disable ZIO.Andrew Vasquez
ISP23xx and ISP24xx chips have support for an adaptive method of posting SCSI command completions for multiple SCSI commands during a single system interrupt. SCSI commands are placed on the system response queue without interrupting the host until 1) a delay timer expires; or 2) a SCSI command completes with an error. As long as the host software (qla2xxx) services the response queue for completions (this polling is done during queuecommand()) within the 'delay timer' period, the firmware will not generate system interrupt.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
