24 ** (Kornel Wieliczek's comment)

26 ** occur segmentation fault,
27 ** if RAID adapter does not on PCI slot
28 ** and modprobe/rmmod this driver twice.
29 ** bug fix enormous stack usage (Adrian Bunk's comment)
30 ** 1.20.00.08 6/23/2005 Erich Chen bug fix with abort command,
31 ** in case of heavy loading when sata cable
32 ** working on low quality connection
33 ** 1.20.00.09 9/12/2005 Erich Chen bug fix with abort command handling, firmware version check
34 ** and firmware update notify for hardware bug fix
35 ** 1.20.00.10 9/23/2005 Erich Chen enhance sysfs function for change driver's max tag Q number.
36 ** add DMA_64BIT_MASK for backward compatible with all 2.6.x

38 ** add ioctl code 'ARCMSR_IOCTL_FLUSH_ADAPTER_CACHE'
39 ** customer can send this command for sync raid volume data

43 ** change 64bit pci_set_consistent_dma_mask into 32bit
44 ** increcct adapter count if adapter initialize fail.
45 ** miss edit at arcmsr_build_ccb....
46 ** psge += sizeof(struct _SG64ENTRY *) =>
47 ** psge += sizeof(struct _SG64ENTRY)
48 ** 64 bits sg entry would be incorrectly calculated
49 ** thanks Kornel Wieliczek give me kindly notify
50 ** and detail description
51 ** 1.20.00.13 11/15/2005 Erich Chen scheduling pending ccb with FIFO
52 ** change the architecture of arcmsr command queue list
53 ** for linux standard list
54 ** enable usage of pci message signal interrupt
55 ** follow Randy.Danlup kindness suggestion cleanup this code
56 ** 1.20.00.14 05/02/2007 Erich Chen & Nick Cheng
57 ** 1.implement PCI-Express error recovery function and AER capability
58 ** 2.implement the selection of ARCMSR_MAX_XFER_SECTORS_B=4096
59 ** if firmware version is newer than 1.42
60 ** 3.modify arcmsr_iop_reset to improve the ability
61 ** 4.modify the ISR, arcmsr_interrupt routine,to prevent the
62 ** inconsistency with sg_mod driver if application directly calls
63 ** the arcmsr driver w/o passing through scsi mid layer
64 ** specially thanks to Yanmin Zhang's openhanded help about AER
65 ** 1.20.00.15 08/30/2007 Erich Chen & Nick Cheng
66 ** 1. support ARC1200/1201/1202 SATA RAID adapter, which is named
67 ** ACB_ADAPTER_TYPE_B
68 ** 2. modify the arcmsr_pci_slot_reset function
69 ** 3. modify the arcmsr_pci_ers_disconnect_forepart function
70 ** 4. modify the arcmsr_pci_ers_need_reset_forepart function
71 ** 1.20.00.15 09/27/2007 Erich Chen & Nick Cheng
72 ** 1. add arcmsr_enable_eoi_mode() on adapter Type B
73 ** 2. add readl(reg->iop2drv_doorbell_reg) in arcmsr_handle_hbb_isr()
74 ** in case of the doorbell interrupt clearance is cached
75 ** 1.20.00.15 10/01/2007 Erich Chen & Nick Cheng
76 ** 1. modify acb->devstate[i][j]
77 ** as ARECA_RAID_GOOD instead of
78 ** ARECA_RAID_GONE in arcmsr_alloc_ccb_pool
79 ** 1.20.00.15 11/06/2007 Erich Chen & Nick Cheng
80 ** 1. add conditional declaration for
81 ** arcmsr_pci_error_detected() and
82 ** arcmsr_pci_slot_reset
83 ** 1.20.00.15 11/23/2007 Erich Chen & Nick Cheng
84 ** 1.check if the sg list member number
85 ** exceeds arcmsr default limit in arcmsr_build_ccb()
86 ** 2.change the returned value type of arcmsr_build_ccb()
87 ** from "void" to "int"
88 ** 3.add the conditional check if arcmsr_build_ccb()
89 ** returns FAILED
90 ** 1.20.00.15 12/04/2007 Erich Chen & Nick Cheng
91 ** 1. modify arcmsr_drain_donequeue() to ignore unknown
92 ** command and let kernel process command timeout.
93 ** This could handle IO request violating max. segments
94 ** while Linux XFS over DM-CRYPT.
95 ** Thanks to Milan Broz's comments <mbroz@redhat.com>
96 ** 1.20.00.15 12/24/2007 Erich Chen & Nick Cheng
97 ** 1.fix the portability problems
98 ** 2.fix type B where we should _not_ iounmap() acb->pmu;
99 ** it's not ioremapped.
100 ** 3.add return -ENOMEM if ioremap() fails
101 ** 4.transfer IS_SG64_ADDR w/ cpu_to_le32()
102 ** in arcmsr_build_ccb
103 ** 5. modify acb->devstate[i][j] as ARECA_RAID_GONE instead of
104 ** ARECA_RAID_GOOD in arcmsr_alloc_ccb_pool()
105 ** 6.fix arcmsr_cdb->Context as (unsigned long)arcmsr_cdb
106 ** 7.add the checking state of
107 ** (outbound_intstatus & ARCMSR_MU_OUTBOUND_HANDLE_INT) == 0
108 ** in arcmsr_handle_hba_isr
109 ** 8.replace pci_alloc_consistent()/pci_free_consistent() with kmalloc()/kfree() in arcmsr_iop_message_xfer()
110 ** 9. fix the release of dma memory for type B in arcmsr_free_ccb_pool()
111 ** 10.fix the arcmsr_polling_hbb_ccbdone()
112 ** 1.20.00.15 02/27/2008 Erich Chen & Nick Cheng
113 ** 1.arcmsr_iop_message_xfer() is called from atomic context under the
114 ** queuecommand scsi_host_template handler. James Bottomley pointed out
115 ** that the current GFP_KERNEL|GFP_DMA flags are wrong: firstly we are in
116 ** atomic context, secondly this memory is not used for DMA.
117 ** Also removed some unneeded casts. Thanks to Daniel Drake <dsd@gentoo.org>
