NVMe: Abort timed out commands

2014-01-28T00:27:53Z

Send nvme abort command to io requests that have timed out on an initialized device. If the command is not returned after another timeout, schedule the controller for reset. Signed-off-by: Keith Busch [fix endianness issues] Signed-off-by: Matthew Wilcox

NVMe: Schedule reset for failed controllers

2014-01-28T00:20:02Z

Schedules a controller reset when it indicates it has a failed status. If the device does not become ready after a reset, the pci device will be scheduled for removal. Signed-off-by: Keith Busch [fixed checkpatch issue] Signed-off-by: Matthew Wilcox

NVMe: Device resume error handling

2013-12-16T20:54:39Z

Adds controller error handling on resume power management. If the device fails to initialize, the device is queued for a reset. If the reset fails, a thread is spawned to remove the pci device. If the device resumes as "busy", the device is responding to admin commands but will not create IO queues. In this case, we need to remove the gendisks and free the IO queues since they can't be used and may be holding bios in their lists. From testing, the dma pools require a pci device so this had to change the pci driver 'remove' to release the dma resources in line with that call instead of after all references to the device are released.

NVMe: compat SG_IO ioctl

2013-12-16T20:49:40Z

For 32-bit versions of sg3-utils running on a 64-bit system. This is mostly a copy from the relevent portions of fs/compat_ioctl.c, with slight modifications for going through block_device_operations.

NVMe: Avoid shift operation when writing cq head doorbell

2013-11-18T22:10:51Z

Changes the type of dev->db_stride to unsigned and changes the value stored there to be 1 << the current value. Then there is less calculation to be done at completion time. Signed-off-by: Haiyan Hu Signed-off-by: Matthew Wilcox

NVMe: Use normal shutdown

2013-09-03T20:40:32Z

The NVMe spec recommends using the shutdown normal sequence when safely taking the controller offline instead of hitting CC.EN on the next start-up to reset the controller. The spec recommends a minimum of 1 second for the shutdown complete. This patch waits 2 seconds to be on the safe side. Signed-off-by: Keith Busch Signed-off-by: Matthew Wilcox

NVMe: Namespace IDs are unsigned

2013-09-03T20:32:26Z

The 'Number of Namespaces' read from the device was being treated as signed, which would cause us to not scan any namespaces for a device with more than 2 billion namespaces. That led to noticing that the namespace ID was also being treated as signed, which could lead to the result from NVME_IOCTL_ID being treated as an error code. Signed-off-by: Matthew Wilcox

NVMe: Split header file into user-visible and kernel-visible pieces

2013-09-03T20:32:25Z

To build user programs that call the NVMe ioctls, we need to have a user header file. Catch up to the new way of doing that by splitting the header file into kernel and uapi portions. Signed-off-by: Matthew Wilcox

NVMe: Disk IO statistics

2013-06-20T16:06:35Z

Add io stats accounting for bio requests so nvme block devices show useful disk stats. Signed-off-by: Keith Busch Signed-off-by: Matthew Wilcox

NVMe: Simplify Firmware Activate code slightly

2013-05-08T13:55:05Z

Add definitions for the three Firmware Activate actions, and change the SCSI translation code to construct the command into a temporary variable instead of translating the endianness back-and-forth. Signed-off-by: Matthew Wilcox Reviewed-by: Vishal Verma
