Linux-2.6.12-rc2v2.6.12-rc2
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!

+ * QLogic ISP2200 and ISP2300 Linux Driver Revision List File.
+ *
+ ********************************************************************
+ *
+ * Revision History
+ *
+ * Rev 8.00.00b8 December 5, 2003 AV
+ * - Instruct mid-layer to perform initial scan.
+ *
+ * Rev 8.00.00b7 December 5, 2003 AV
+ * - Resync with Linux Kernel 2.6.0-test11.
+ * - Add basic NVRAM parser (extras/qla_nvr).
+ *
+ * Rev 8.00.00b7-pre11 December 3, 2003 AV
+ * - Sanitize the scsi_qla_host structure:
+ * - Purge unused elements.
+ * - Reorganize high-priority members (cache coherency).
+ * - Add support for NVRAM access via a sysfs binary attribute:
+ * - Consolidate semaphore locking access.
+ * - Fix more PCI posting issues.
+ * - Add extras directory for dump/NVRAM tools.
+ * - Remove unused qla_vendor.c file.
+ *
+ * Rev 8.00.00b7-pre11 November 26, 2003 DG/AV
+ * - Merge several patches from Christoph Hellwig [hch@lst.de]:
+ * - in Linux 2.6 both pci and the scsi layer use the generic
+ * dma direction bits, use them directly instead of the scsi
+ * and pci variants and the (noop) conversion routines.
+ * - Fix _IOXX_BAD() usage for external IOCTL interface.
+ * - Use atomic construct for HA loop_state member.
+ * - Add generic model description text for HBA types.
+ *
+ * Rev 8.00.00b7-pre5 November 17, 2003 AV
+ * - Merge several patches from Christoph Hellwig [hch@lst.de]:
+ * - patch to split the driver into a common qla2xxx.ko and a
+ * qla2?00.ko for each HBA type - the latter modules are
+ * only very small wrappers, mostly for the firmware
+ * images, all the meat is in the common qla2xxx.ko.
+ * - make the failover code optional.
+ * - kill useless lock_kernel in dpc thread startup.
+ * - no need for modversions hacks in 2.6 (or 2.4).
+ * - kill qla2x00_register_with_Linux.
+ * - simplify EH code, cmd or it's hostdata can't be NULL, no
+ * need to search whether the host it's ours, the midlayer
+ * makes sure it won't call into a driver for some else
+ * host.
+ * - Merge several patches from Jes Sorensen
+ * [jes@wildopensource.com]:
+ * - Call qla2x00_config_dma_addressing() before performing
+ * any consistent allocations. This is required since the
+ * dma mask settings will affect the memory
+ * pci_alloc_consistent() will return.
+ * - Call pci_set_consistent_dma_mask() to allow for 64 bit
+ * consistent allocations, required on some platforms such
+ * as the SN2.
+ * - Wait 20 usecs (not sure how long is really necessary,
+ * but this seems safe) after setting CSR_ISP_SOFT_RESET in
+ * the ctrl_status register as the card doesn't respond to
+ * PCI reads while in reset state. This causes a machine
+ * check on some architectures.
+ * - Flush PCI writes before calling udelay() to ensure the
+ * write is not sitting idle in-flight for a while before
+ * hitting the hardware.
+ * - Include linux/vmalloc.h in qla_os.c since it uses
+ * vmalloc().
+ * - Use auto-negotiate link speed when using default
+ * parameters rather than NVRAM settings. Disable NVRAM
+ * reading on SN2 since it's not possible to execute the
+ * HBA's BIOS on an SN2. I suggest doing something similar
+ * for all architectures that do not provide x86 BIOS
+ * emulation.
+ * - Clean-up slab-cache allocations:
+ * - locking.
+ * - mempool allocations in case of low-memory situations.
+ * - Fallback to GA_NXT scan if GID_PT call returns more than
+ * MAX_FIBRE_DEVICES.
+ * - Preserve iterating port ID across GA_NXT calls in
+ * qla2x00_find_all_fabric_devs().
+ * - Pre-calculate ASCII firmware dump length as to not incur the
+ * cost-to-calculate at each invocation of a read().
+ *
+ * Rev 8.00.00b6 November 4, 2003 AV
+ * - Add new 2300 TPX firmware (3.02.18).
+ *
+ * Rev 8.00.00b6-pre25 October 20, 2003 RA/AV
+ * - Resync with Linux Kernel 2.6.0-test9.
+ * - Rework firmware dump process:
+ * - Use binary attribute within sysfs tree.
+ * - Add user-space tool (gdump.sh) to retrieve formatted
+ * buffer.
+ * - Add ISP2100 support.
+ * - Use a slab cache for SRB allocations to reduce memory
+ * pressure.
+ * - Initial conversion of driver logging methods to a new
+ * qla_printk() function which uses dev_printk (Daniel
+ * Stekloff, IBM).
+ * - Further reduce stack usage in qla2x00_configure_local_loop()
+ * and qla2x00_find_all_fabric_devs().
+ * - Separate port state used for routing of I/O's from port
+ * mgmt-login retry etc.
+ *
+ * Rev 8.00.00b6-pre19 October 13, 2003 AV
+ * - Resync with Linux Kernel 2.6.0-test7-bk5.
+ * - Add intelligent RSCN event handling:
+ * - reduce scan time during 'port' RSCN events by only
+ * querying specified port ids.
+ * - Available on ISP23xx cards only.
+ * - Increase maximum number of recognizable targets from 256
+ * to 512.
+ * - Backend changes were previously added to support TPX
+ * (2K logins) firmware. Mid-layer can now scan for targets
+ * (H, B, T, L) where 512 < T >= 0.
+ * - Remove IP support from driver.
+ * - Switch firmware types from IP->TP for ISP22xx and
+ * IPX->TPX for ISP23xx cards.
+ * - Remove files qla_ip.[ch].
+ * - Remove type designations from firmware filenames.

+ * Rev 8.00.00b6-pre11 September 15, 2003 DG/AV
+ * - Resync with 6.06.00.
+ * - Resync with Linux Kernel 2.6.0-test5-bk3.
+ * - Add new 2300 IPX firmware (3.02.15).
+ *
+ * Rev 8.00.00b5 July 31, 2003 AV
+ * - Always create an fc_lun_t entry for lun 0 - as the mid-
+ * layer requires access to this lun for discovery to occur.
+ * - General sanitizing:
+ * - Add generic firmware option definitions.
+ * - Generalize retrieval/update of firmware options.
+ * - Fix compile errors which occur with extended debug.
+ * - Handle failure cases for scsi_add_host() and
+ * down_interruptible().
+ * - Host template updates:
+ * - Use standard bios_param callback function.
+ * - Disable clustering.
+ * - Remove unchecked_is_dma entry.
+ *
+ * Rev 8.00.00b5-pre5 July 29, 2003 DG/AV
+ * - Resync with 6.06.00b13.
+ * - Resync with Linux Kernel 2.6.0-test2.
+ * - Pass the complete loop_id, not the masked (0xff) value
+ * while issuing mailbox commands (qla_mbx.c/qla_fo.c/
+ * qla_iocb.c/qla_init.c).
+ * - Properly handle zero-length return status for an RLC CDB.
+ * - Create an fclun_t structure for 'disconnected' luns,
+ * peripheral-qualifier of 001b.
+ * - Remove unused LIP-sequence register access during AE 8010.
+ * - Generalize qla2x00_mark_device_lost() to handle forced
+ * login request -- modify all direct/indirect invocations
+ * with proper flag.
+ * - Save RSCN notification (AE 8015h) data in a proper and
+ * consistent format (domain, area, al_pa).

+ * - scsi_qla_host structure member reordering for cache-line
+ * coherency.
+ * - Remove unused SCSI opcodes, endian-swap definitions.
+ * - Remove CMD_* pre-processor defines.
+ * - Remove unused SCSIFCHOTSWAP/GAMAP/MULTIHOST codes.
+ * - Backout patch which added a per-scsi_qla_host scsi host
+ * spinlock, since mid-layer already defines one.
+ * - Add new 2300 IPX firmware (3.02.15).
+ *
+ * Rev 8.00.00b4 July 14, 2003 RA/DG/AV
+ * - Resync with 6.06.00b12.
+ * - Resync with Linux Kernel 2.6.0-test1.
+ * - Remove IOCB throttling code -- originally #if'd.
+ * - Remove apidev_*() routines since proc_mknod() has been
+ * removed -- need alternate IOCTL interface.
+ * - Merge several performance/fix patches from Arjan van de
+ * Ven:
+ * - Undefined operation >> 32.
+ * - No need to acquire mid-layer lock during command
+ * callback.
+ * - Use a per-HBA mid-layer lock.
+ * - Use a non-locked cycle for setting the count of the
+ * newly allocated sp (qla2x00_get_new_sp()).

+ * - Reduce cacheline bouncing by having I/Os submitted
+ * by the IRQ handler.
+ * - Remove extraneous calls to qla2x00_next() during I/O
+ * queuing.
+ * - Use list_splice_init() during qla2x00_done() handling
+ * of commands to reduce list_lock contention.
