From: Bradley Grove During hibernation, the HBA firmware may lose power and forget the device id info. This causes the HBA to reject IO upon resume. The fix is to call the libsas power management routines to make the domain device forgetful. This patch also changes the value of pm8001_flags during resume to allow completions to work.

Re: [PATCH 0/2] pm80xx: Fix ATTO pm8001 based HBA support
James, There were a couple of patches that I expected to be added during the 3.14-rc1 merge window that weren't. Specifically: http://marc.info/?l=linux-scsi&m=138753665607127&w=2 http://marc.info/?l=linux-scsi&m=138738970431549&w=2 Can you explain why they weren't included?

ATTO 6G SAS/SATA HBA Driver
James, Now that we are finishing up development for our esas2r driver, we are planning to start work on a kernel driver for our PM8001 based 6G SAS/SATA HBA product. We have some questions about the best way to proceed. While we haven't done thorough testing, our hardware appears to work with the existing PM8001 kernel driver. The problem is that the existing kernel driver doesn't support all the features of the hardware or match the feature set of the current closed source driver. For example, our closed source driver supports SES emulation over I2C and SGPIO. Our closed source driver also has custom PHY settings to support longer cable lengths. We also have a set of propriety management tools we'd like to work with the open source driver, though it looks like the PM8001's sysfs interface provides most of the functionality we need. What are our options for supporting these features? I see that Adaptec had an out-of-tree driver for their PM8001 card that supports additional features. We'd prefer to have a kernel driver that fully supports our hardware, either based on the existing PM8001 driver or our closed source code base. Is that possible? -- Bradley Grove System Software Engineer ATTO Technology, Inc.

[PATCH v4 00/10] SCSI: esas2r: ATTO Technology ExpressSAS 6G SAS/SATA RAID Adapter Driver
This is a new driver for ATTO Technology's ExpressSAS series of hardware RAID adapters. It supports the following adapters: - ExpressSAS R60F - ExpressSAS R680 - ExpressSAS R608 - ExpressSAS R644 This patch is split into ten parts, all of which need to be applied to build the driver. Changes Since V3: - Addressed some warnings reported by checkpatch script, mostly whitespace Changes since V2: - Fix spurious ioctl error logging and memory corruption occuring with non-IO VDA requests - Use kernel's schedule_timeout_interruptable() rather than our own own stall function - Removed a UDP socket based interface used by our closed source configuration tool Changes since V1: - We now use the kernel's list structs and alignment macros rather than our own implementations - Fix to PCIe address size declaration when compiling on 32-bit architectures - Use memcpy() instead opf memmove() where appropriate - Fixes for big-endian architectures - Removed unneeded MSI configuration code - Simplified memory allocation during init - Code formatting cleanup Bradley Grove (10): SCSI: esas2r: Add main header file SCSI: esas2r: Add main file SCSI: esas2r: Add initialization functions SCSI: esas2r: Add device discovery and logging functions SCSI: esas2r: Add interrupt and IO functions SCSI: esas2r: Add flash and target database functions SCSI: esas2r: Add IOCTL header file SCSI: esas2r: Add IOCTL functions SCSI: esas2r: Add ATTO VDA Firmware API headers and functions.

James, Do you have any comments on this last patch post? I probably shouldn't have posted it as an RFC. We've completed our internal testing of the driver, and I think it's probably ready to submit.

[PATCH v3 00/10] [RFC] SCSI: esas2r: ATTO Technology ExpressSAS 6G SAS/SATA RAID Adapter Driver
This is a new driver for ATTO Technology's ExpressSAS series of hardware RAID adapters. It supports the following adapters: - ExpressSAS R60F - ExpressSAS R680 - ExpressSAS R608 - ExpressSAS R644 This patch is split into ten parts, all of which need to be applied to build the driver. Changes since V2: - Fix spurious ioctl error logging and memory corruption occuring with non-IO VDA requests - Use kernel's schedule_timeout_interruptable() rather than our own own stall function - Removed a UDP socket based interface used by our closed source configuration tool Changes since V1: - We now use the kernel's list structs and alignment macros rather than our own implementations - Fix to PCIe address size declaration when compiling on 32-bit architectures - Use memcpy() instead opf memmove() where appropriate - Fixes for big-endian architectures - Removed unneeded MSI configuration code - Simplified memory allocation during init - Code formatting cleanup Bradley Grove (10): [RFC] SCSI: esas2r: Add main header file [RFC] SCSI: esas2r: Add main file [RFC] SCSI: esas2r: Add initialization functions [RFC] SCSI: esas2r: Add device discovery and logging functions [RFC] SCSI: esas2r: Add interrupt and IO functions [RFC] SCSI: esas2r: Add flash and target database functions [RFC] SCSI: esas2r: Add IOCTL header file [RFC] SCSI: esas2r: Add IOCTL functions [RFC] SCSI: esas2r: Add ATTO VDA Firmware API headers and functions.

[PATCH v2 00/10] [RFC] SCSI: esas2r: ATTO Technology ExpressSAS 6G SAS/SATA RAID Adapter Driver
This is a new driver for ATTO Technology's ExpressSAS series of hardware RAID adapters. It supports the following adapters: - ExpressSAS R60F - ExpressSAS R680 - ExpressSAS R608 - ExpressSAS R644 This patch is split into ten parts, all of which need to be applied to build the driver. Changes since V1: - We now use the kernel's list structs and alignment macros rather than our own implementations - Fix to PCIe address size declaration when compiling on 32-bit architectures - Use memcpy() instead opf memmove() where appropriate - Fixes for big-endian architectures - Removed unneeded MSI configuration code - Simplified memory allocation during init - Code formatting cleanup Bradley Grove (10): [RFC] SCSI: esas2r: Add main header file [RFC] SCSI: esas2r: Add main file [RFC] SCSI: esas2r: Add initialization functions [RFC] SCSI: esas2r: Add device discovery and logging functions [RFC] SCSI: esas2r: Add interrupt and IO functions [RFC] SCSI: esas2r: Add flash and target database functions [RFC] SCSI: esas2r: Add IOCTL header file [RFC] SCSI: esas2r: Add IOCTL functions [RFC] SCSI: esas2r: Add ATTO VDA Firmware API headers and functions.

[PATCH 00/10] [RFC] SCSI: esas2r: ATTO Technology ExpressSAS 6G SAS/SATA RAID Adapter Driver
This is a new driver for ATTO Technology's ExpressSAS series of hardware RAID adapters. It supports the following adapters: - ExpressSAS R60F - ExpressSAS R680 - ExpressSAS R608 - ExpressSAS R644 This patch is split into ten parts to make reviewing easier. You'll need to apply all of them to get the complete patch. We have done some testing under x86 and x64 architectures, but the code is still under development and we expect to find additional issues. We appreciate any review comments.
