| ** (Kornel Wieliczek's comment) | |
| ** 1.20.00.07 3/23/2005 Erich Chen bug fix with arcmsr_scsi_host_template_init | |
| ** occur segmentation fault, | |
| ** if RAID adapter does not on PCI slot | |
| ** and modprobe/rmmod this driver twice. | |
| ** bug fix enormous stack usage (Adrian Bunk's comment) | |
| ** 1.20.00.08 6/23/2005 Erich Chen bug fix with abort command, | |
| ** in case of heavy loading when sata cable | |
| ** working on low quality connection | |
| ** 1.20.00.09 9/12/2005 Erich Chen bug fix with abort command handling, firmware version check | |
| ** and firmware update notify for hardware bug fix | |

| ** add DMA_64BIT_MASK for backward compatible with all 2.6.x | |

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