* [SCSI] qla2xxx: Explicitly set the execution-throttle with recent ISPs.Andrew Vasquez2009-04-032-4/+9
| | | | | | | | | | | | Firmware semantics changed for 24xx and above ISPs in their handling of the specified execution-throttle passed during firmware initialization. The original codes use of a theoretical maximum (0xffff, as carried over from earlier ISPs) could in fact act as a throttle in some circumstances. Now set the value based of the firmware's own 'resource' (exchange IOCBs) capabilities.

* [SCSI] qla2xxx: Reduce request queue-size overhead with recent ISPs.Andrew Vasquez2009-04-032-64/+6
| | | | | | | | | | | | The original code to 'resize request-queues' based on iocb-counts and employed during early ISP23xx testing was too overly-pessimistic with regards to latencies in the firmware pulling requests. Recent ISPs can easily keep up processing a stream of commands from an abbreviated (effectively, half the original size) queue.

* [SCSI] qla2xxx: Drop use of IRQF_DISABLE.Giridhar Malavali2009-04-031-1/+1
| | | | | | | | | | | | | | | When IRQs are shared by multiple controllers and if the first one to register does not disable the IRQ, then IRQ will be enabled for all other controllers by default, irrespective of their setting. With IRQF_DISABLED registration, the driver interrupt routine was called with interrupt enabled always. Disbaling the registration with IRQF_DISABLED, since driver code is re-entrant safe and all critical sections are guarded with interrupt safe locks.

| | | | | | | | | | | | | Given the low-level interface varies from one flash-part manufacturer to the next, the Flash-Access-Control (FAC) mailbox command makes the specific flash type transparent to the driver by encapsulating a basic set of accessor and update routines.

* [SCSI] qla2xxx: Correct regression in DMA-mask setting prior to allocations.Andrew Vasquez2009-01-251-6/+2
| | | | | | | | | | | | Jeremy Higdon noted (http://marc.info/?l=linux-scsi&m=123262143131788&w=2) that the rework done in commit e315cd28b9ef0d7b71e462ac16e18dbaa2f5adfe was not setting the proper consistent and streaming DMA masks prior to memory allocations. Correct this and remove the unnecessary prototype. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
* [SCSI] qla2xxx: Correct descriptions in flash manipulation routines.Joe Carnuccio2009-01-251-3/+3
| | | | | | | | | | | | | | | | When clearing the flash device's SR, the comment is incorrect... clearing the SR is 2 steps: 1. the SR protect bit is 1, so the first write zero clears only that bit, 2. the SR protect bit is now 0, so the next write zero clears the remaining bits. The sector erase debug print more correctly identifies that the erase failed.

* [SCSI] qla2xxx: Correct regression in EH abort handling.Andrew Vasquez2009-01-251-0/+1
| | | | | | | | | | Commit 73208dfd7ab19f379d73e8a0fbf30f92c203e5e8 (qla2xxx: add support for multi-queue adapter) inadvertently backed-out the fix in 5bff55db3dc4d659f46b4d2fce2f61c1964c2762 (qla2xxx: Return a FAILED status when abort mailbox-command fails.).

* [SCSI] qla2xxx: Correct endianness issue during flash manipulation.Andrew Vasquez2009-01-251-5/+2
| | | | | | | | | The flash data was incorrectly being converted (cpu_to_le32()) when using the bulk-flash-write mailbox command (ISP25xx and above). Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

* [SCSI] qla2xxx: Modify firmware-load order precedence for ISP81XX parts.Andrew Vasquez2009-01-253-7/+46
| | | | | | | | | | | | | | Pre-ISP81XX parts (including ISP24xx and ISP25xx) could contain a firmware image within a segment of flash, driver would fallback to loading this firmware if the request-firmware interface failed (userspace .bin file). Moving forward, all ISP81XX parts will ship with a suggested-to-be-used firmware image within flash which all driver should first attempt to load. If the flash firmware load fails, the driver will then fallback to loading firmware via the request-firmware interface (ql8100_fw.bin).

* [SCSI] qla2xxx: Always serialize mailbox command execution.Andrew Vasquez2009-01-251-10/+6
| | | | | | | | | | | Original code would incorrectly bypass serialization if the DPC thread were performing a big-hammer operation (ISP abort). This short circuit, though rare, would subsequently stomp on a secondary thread's mailbox command execution. Found during ISP81XX testing.
