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. - * -
