- * 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.

- * 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.

- * - 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.

- * IPX->TPX for ISP23xx cards.

- * 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.

- * 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.
