| ** modify PCCB POOL allocated by "dma_alloc_coherent" |
| ** (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 |
| ** 1.20.00.10 9/23/2005 Erich Chen enhance sysfs function for change driver's max tag Q number. |
| ** add DMA_64BIT_MASK for backward compatible with all 2.6.x |
| ** add some useful message for abort command |
| ** add ioctl code 'ARCMSR_IOCTL_FLUSH_ADAPTER_CACHE' |
| ** customer can send this command for sync raid volume data |
| ** 1.20.00.11 9/29/2005 Erich Chen by comment of Arjan van de Ven fix incorrect msleep redefine |
| ** cast off sizeof(dma_addr_t) condition for 64bit pci_set_dma_mask |
| ** 1.20.00.12 9/30/2005 Erich Chen bug fix with 64bit platform's ccbs using if over 4G system memory |
| ** 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() |
