Subject: [scsi] areca driver update
Message-id: 4765ACD2.5090206@redhat.com
O-Subject: [RHEL5.2 PATCH] bz363961: Areca driver update 1/2
Bugzilla: 363961
The patch below comes from Areca, and brings the RHEL-5 driver up to
date for 5.2. It also adds support for new hardware.
I have tested it using verify-data (x86_64).
The first part of the patch is accepted upstream,
the patch in the second part was not yet posted, it should help to resolve
the bug with XFS over DM-CRYPT http://lkml.org/lkml/2007/6/26/64
And here is the first part:

** follow Randy.Danlup kindness suggestion cleanup this code
-**************************************************************************
\ No newline at end of file
+** 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.RH 11/06/2007 Erich Chen & Nick Cheng
+** This is the specific version fot RHEL5.2 exclusively.
+** It is the variant of arcmsr.1.20.00.15 11/06/2007.
+** 1. delete pci_error_handler(), which is supported after kernel 2.6.19
+** 2.in arcmsr_build_ccb(), arcmsr_iop_message_xfer()
+** ,arcmsr_pci_unmap_dma and arcmsr_handle_virtual_command,
+** replace to invoke pci_map_sg
+** , scsi_cmnd.use_sg and scsi_cmnd.request_buffer
+** to get the material in scatter-gather list
+** from upper scsi layer .
+** 3.check if the sg list member number
+** exceeds arcmsr default limit in arcmsr_build_ccb()
+** 4.change the returned value type of arcmsr_build_ccb()
+** from "void" to "int"
+** 5.add the conditional check if arcmsr_build_ccb()
+** returns FAILED
+** This is quoted as the methodology in arcmsr.1.20.00.13.
