31 | ** in case of heavy loading when sata cable |
32 | ** working on low quality connection |

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> |
