2006-05-20[SCSI] qla2xxx: Use FW calculated residual count for underrun handling.Ravi Anand
With ISP24XX and ISP54XX parts. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-03-12[SCSI] qla2xxx: Add ISP54xx support.andrew.vasquez@qlogic.com
Chip is similar in form to our ISP24xx offering. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2006-03-02[SCSI] qla2xxx: use kthread_ APIChristoph Hellwig
Use the kthread_ API instead of opencoding lots of hairy code for kernel thread creation and teardown. Also switch from semaphore-based thread wakeup to wake_up_process.

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.

2006-01-14[SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine.andrew.vasquez@qlogic.com
Given the semantic changes in both the device-model and fc-transport APIs, the driver's handling of port-type RSCNs via a series of ADISCs and PLOGIs can cause series of badness ranging from unexpectedly device loss to devices not being discovered. In the interim, disable (via a module-parameter) this feature and allow RSCN management to continue to occur within the driver's DPC thread.

2006-01-14[SCSI] qla2xxx: Drop noisy 'UNDERRUN' status message.andrew.vasquez@qlogic.com
There's no point in displaying the message during a valid underrun case. Limit the message to potentially problematic cases. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-12-07[SCSI] qla2xxx: Correct short-WRITE status handling.Andrew Vasquez
Properly check FC_RESID for any non-transfered bytes regardless of firmware completion status. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

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.

2005-07-14[SCSI] qla2xxx: Code scrubbing.Andrew Vasquez
Code scrubbing. - Remove trailing whitespace from driver files. - Remove unused #defines and inlines. - Standardize on C comments (// -> /* */) Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-07-14[SCSI] qla2xxx: Add ISP24xx ISR routines.Andrew Vasquez
Add ISP24xx ISR routines. Add appropriate glue-code for ISP24xx support -- this included generalizing some of the core handling routines (qla2x00_async_event() [pull-up retrieval of mailbox values] and qla2x00_status_entry()]. Fixup 2100/2300 ISRs to handle the new conventions. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-07-14[SCSI] qla2xxx: Add ISP24xx definitions.Andrew Vasquez
Add ISP24xx definitions. Add requisite structure definitions and #define's for ISP24xx support. Also drop volatile modifiers from device_reg_* register layouts as the members are never really accessed, only their offsets within the layout are used during reads and writes.

2005-07-14[SCSI] qla2xxx: Factor-out ISP specific functions to method-based call tables.Andrew Vasquez
Factor-out ISP specific functions to method-based call tables. In anticipation of ISP24xx/ISP25xx support, factor-out ISP specific functions into a method-based call table. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Remove internal lun discovery routines and support structures. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
2005-04-18[PATCH] qla2xxx: remove internal queuing...
Remove internal command queuing from the driver. As is, this driver cannot tolerate cable-pulls as I/Os will begin to fail by the upper layers. o Should be used in conjuction with the 11-fc_rport_adds_2.diff patch. o Removes qla_listops.h file -- no longer needed.

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
