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). + * - General sanitizing: + * - 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()). + * -
