Add support for legacy boards, ensuring to enable the driver for those boards only when 'hpsa_allow_any' is set. The attribute 'legacy_board' is set to '1' if the device is a legacy board, and '0' otherwise. Signed-off-by:

While the 'state' attribute can (and will) change occasionally, calling 'poll()' or 'select()' on it fails as sysfs is never notified that the state has changed. With this patch calling 'poll()' or 'select()' will work properly. Signed-off-by:

Since switching to blk-mq as the default in commit 5c279bd9 ("scsi: default to scsi-mq"), virtio-scsi LUNs consume about 10x as much kernel memory. qemu currently allocates a fixed 128 entry virtqueue. can_queue currently is set to 1024. But with indirect descriptors, each command in the queue takes 1 virtqueue entry, so the number of commands which can be queued is equal to the length of the virtqueue. Note I intend to send a patch to qemu to allow the virtqueue size to be configured from the qemu command line. Signed-off-by:

If using indirect descriptors, you can make the total_sg as large as you want. If not, BUG is too serious because the function later returns -ENOSPC. Signed-off-by:

[qed_sp_iscsi_func_start:189(host_7-0)]Cannot satisfy CQ amount. Queues requested 8, CQs available 4. Aborting function start Above condition will resolve as management firmware is capable of telling us the number of CQs available for a given PF, qed will communicate the same number to qedi, So that qedi will know how much CQs are allowed.

This patch is a fix related to freeing a device in v2 hw driver. Before, we polled to ITCT CLR interrupt to check if a device is free. This was error prone, as if the interrupt doesn't occur in 10us, we miss processing it. To avoid this situation, service this interrupt and sync the event with a completion. Signed-off-by:

This patch removes some repeated configurations: (1) The device id of the device is already set in the alloc function, so we don't need to modify in free device function. (2) Field dev_type and dev_status are configured in hisi_sas_dev_gone(), so there is no need for repeated config in free_device_v3_hw. Signed-off-by: -

This patch provides fixes for the following issues: 1. Fix issue of controller reset required to send commands. For reset process, it may be required to send commands to the controller, but not during soft reset. So add HISI_SAS_NOT_ACCEPT_CMD_BIT to prevent executing a task during this period. 2. Send a broadcast event in rescan topology to detect any topology changes during reset. 3. Previously it was not ensured that libsas has processed the PHY up and down events after reset. Potentially this could cause an issue that we still process the PHY event after reset. So resolve this by flushing shot workqueue in LLDD reset. 4. Port ID requires refresh after reset. The port ID generated after reset is not guaranteed to be the same as before reset, so it needs to be refreshed for each device's ITCT. Signed-off-by:

Add PQI reset to driver shutdown callback to work around controller bug. During an 1.) OS shutdown or 2.) kexec outside of a kdump, the Linux kernel will clear BME on our controller. If BME is cleared during a controller/host PCIe transfer, the controller will lock up. So we perform a PQI reset in the driver's shutdown callback function to eliminate the possibility of a controller/host PCIe transfer being active when the kernel clears BME immediately after calling the driver's shutdown callback.
