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.
