2 * QLogic ISP2200 and ISP2300 Linux Driver Revision List File.
3 *
4 ********************************************************************
5 *
6 * Revision History
7 *
8 * Rev 8.00.00b8 December 5, 2003 AV
9 * - Instruct mid-layer to perform initial scan.
10 *
11 * Rev 8.00.00b7 December 5, 2003 AV
12 * - Resync with Linux Kernel 2.6.0-test11.
13 * - Add basic NVRAM parser (extras/qla_nvr).
14 *
15 * Rev 8.00.00b7-pre11 December 3, 2003 AV
16 * - Sanitize the scsi_qla_host structure:
17 * - Purge unused elements.
18 * - Reorganize high-priority members (cache coherency).
19 * - Add support for NVRAM access via a sysfs binary attribute:
20 * - Consolidate semaphore locking access.
21 * - Fix more PCI posting issues.
22 * - Add extras directory for dump/NVRAM tools.
23 * - Remove unused qla_vendor.c file.
24 *
25 * Rev 8.00.00b7-pre11 November 26, 2003 DG/AV
26 * - Merge several patches from Christoph Hellwig [hch@lst.de]:
27 * - in Linux 2.6 both pci and the scsi layer use the generic
28 * dma direction bits, use them directly instead of the scsi
29 * and pci variants and the (noop) conversion routines.
30 * - Fix _IOXX_BAD() usage for external IOCTL interface.
31 * - Use atomic construct for HA loop_state member.
32 * - Add generic model description text for HBA types.
33 *
34 * Rev 8.00.00b7-pre5 November 17, 2003 AV
35 * - Merge several patches from Christoph Hellwig [hch@lst.de]:
36 * - patch to split the driver into a common qla2xxx.ko and a
37 * qla2?00.ko for each HBA type - the latter modules are
38 * only very small wrappers, mostly for the firmware
39 * images, all the meat is in the common qla2xxx.ko.
40 * - make the failover code optional.
41 * - kill useless lock_kernel in dpc thread startup.
42 * - no need for modversions hacks in 2.6 (or 2.4).
43 * - kill qla2x00_register_with_Linux.
44 * - simplify EH code, cmd or it's hostdata can't be NULL, no
45 * need to search whether the host it's ours, the midlayer
46 * makes sure it won't call into a driver for some else
47 * host.
48 * - Merge several patches from Jes Sorensen
49 * [jes@wildopensource.com]:
50 * - Call qla2x00_config_dma_addressing() before performing
51 * any consistent allocations. This is required since the
52 * dma mask settings will affect the memory
53 * pci_alloc_consistent() will return.
54 * - Call pci_set_consistent_dma_mask() to allow for 64 bit
55 * consistent allocations, required on some platforms such
56 * as the SN2.
57 * - Wait 20 usecs (not sure how long is really necessary,
58 * but this seems safe) after setting CSR_ISP_SOFT_RESET in
59 * the ctrl_status register as the card doesn't respond to
60 * PCI reads while in reset state. This causes a machine
61 * check on some architectures.
62 * - Flush PCI writes before calling udelay() to ensure the
63 * write is not sitting idle in-flight for a while before
64 * hitting the hardware.
65 * - Include linux/vmalloc.h in qla_os.c since it uses
66 * vmalloc().
67 * - Use auto-negotiate link speed when using default
68 * parameters rather than NVRAM settings. Disable NVRAM
69 * reading on SN2 since it's not possible to execute the
70 * HBA's BIOS on an SN2. I suggest doing something similar
71 * for all architectures that do not provide x86 BIOS
72 * emulation.
73 * - Clean-up slab-cache allocations:
74 * - locking.
75 * - mempool allocations in case of low-memory situations.
76 * - Fallback to GA_NXT scan if GID_PT call returns more than
77 * MAX_FIBRE_DEVICES.
78 * - Preserve iterating port ID across GA_NXT calls in
79 * qla2x00_find_all_fabric_devs().
80 * - Pre-calculate ASCII firmware dump length as to not incur the
81 * cost-to-calculate at each invocation of a read().
82 *
83 * Rev 8.00.00b6 November 4, 2003 AV
84 * - Add new 2300 TPX firmware (3.02.18).
85 *
86 * Rev 8.00.00b6-pre25 October 20, 2003 RA/AV
87 * - Resync with Linux Kernel 2.6.0-test9.
88 * - Rework firmware dump process:
89 * - Use binary attribute within sysfs tree.
90 * - Add user-space tool (gdump.sh) to retrieve formatted
91 * buffer.
92 * - Add ISP2100 support.
93 * - Use a slab cache for SRB allocations to reduce memory
94 * pressure.
95 * - Initial conversion of driver logging methods to a new
96 * qla_printk() function which uses dev_printk (Daniel
97 * Stekloff, IBM).
98 * - Further reduce stack usage in qla2x00_configure_local_loop()
99 * and qla2x00_find_all_fabric_devs().
100 * - Separate port state used for routing of I/O's from port
101 * mgmt-login retry etc.
102 *
103 * Rev 8.00.00b6-pre19 October 13, 2003 AV
104 * - Resync with Linux Kernel 2.6.0-test7-bk5.
105 * - Add intelligent RSCN event handling:
106 * - reduce scan time during 'port' RSCN events by only
107 * querying specified port ids.
108 * - Available on ISP23xx cards only.
109 * - Increase maximum number of recognizable targets from 256
110 * to 512.
111 * - Backend changes were previously added to support TPX
112 * (2K logins) firmware. Mid-layer can now scan for targets
113 * (H, B, T, L) where 512 < T >= 0.
114 * - Remove IP support from driver.
115 * - Switch firmware types from IP->TP for ISP22xx and
116 * IPX->TPX for ISP23xx cards.
117 * - Remove files qla_ip.[ch].
118 * - Remove type designations from firmware filenames.
119 *

121 * - Resync with 6.06.00.
122 * - Resync with Linux Kernel 2.6.0-test5-bk3.
123 * - Add new 2300 IPX firmware (3.02.15).
124 *
125 * Rev 8.00.00b5 July 31, 2003 AV
126 * - Always create an fc_lun_t entry for lun 0 - as the mid-
127 * layer requires access to this lun for discovery to occur.
128 * - General sanitizing:
129 * - Add generic firmware option definitions.
130 * - Generalize retrieval/update of firmware options.
131 * - Fix compile errors which occur with extended debug.
132 * - Handle failure cases for scsi_add_host() and
133 * down_interruptible().
134 * - Host template updates:

141 * - Resync with Linux Kernel 2.6.0-test2.
142 * - Pass the complete loop_id, not the masked (0xff) value
143 * while issuing mailbox commands (qla_mbx.c/qla_fo.c/
144 * qla_iocb.c/qla_init.c).
145 * - Properly handle zero-length return status for an RLC CDB.

147 * peripheral-qualifier of 001b.
148 * - Remove unused LIP-sequence register access during AE 8010.

153 * consistent format (domain, area, al_pa).

156 * coherency.
157 * - Remove unused SCSI opcodes, endian-swap definitions.
158 * - Remove CMD_* pre-processor defines.
159 * - Remove unused SCSIFCHOTSWAP/GAMAP/MULTIHOST codes.
160 * - Backout patch which added a per-scsi_qla_host scsi host
161 * spinlock, since mid-layer already defines one.
162 * - Add new 2300 IPX firmware (3.02.15).

170 * - Merge several performance/fix patches from Arjan van de
171 * Ven:
172 * - Undefined operation >> 32.
173 * - No need to acquire mid-layer lock during command
174 * callback.
175 * - Use a per-HBA mid-layer lock.
176 * - Use a non-locked cycle for setting the count of the
177 * newly allocated sp (qla2x00_get_new_sp()).
178 * - Modify semantic behavior of qla2x00_queuecommand():

400 * an increase in startup time when running against slow
401 * (JBOD) devices.
