Issue: For ISP83XX risc_intr getting clear two times in case of polling mode. risc_intr getting clear from interrupt_service_routine() as well from process_mbox_intr() because of this driver may clear risc_intr without processing interrupt. Fix: Do not clear risc_intr from process_mbox_intr(). Signed-off-by:

If IRQ allocation fails, it means system has run out of interrupt vectors, so fail probe_adapter in case of IRQ allocation failure and dont retry adapter initialization. Signed-off-by:

Camram is reset by FW to default values after reboot/cold boot/pci reset. In case of AER, PCI may need to reset so we need to set correct idc reg value after PCIE error. Signed-off-by:

A quote from SPC-4: "While in the unavailable primary target port asymmetric access state, the device server shall support those of the following commands that it supports while in the active/optimized state: [ ... ] d) SET TARGET PORT GROUPS; [ ... ]". Hence enable sending STPG to a target port group that is in the unavailable state. Signed-off-by:

Don't restart lookup of more stargets in the multi-target case, just arrange to traverse the list once, on the assumption that new targets are always added at the end. There is no guarantee that the target will change state in scsi_target_reap() so we can end up spinning if we restart. Cc: <stable@vger.kernel.org> Acked-by:

Now that the iSeries code is gone the backend abstraction in this driver is no longer necessary, which allows us to consolidate the driver in one file. The side effect is that the module name is now ibmvscsi.ko which matches the driver hotplug name and fixes auto-load issues. [jejb:fix up checkpatch.pl errors] Signed-off-by:

Issue: Device can go to READY state from COLD and skip INITIALIZATION, In this case driver will never set IDC version from function qla4_8xxx_device_bootstrap(). Fix: 1. Set IDC version at start of function qla4_82xx_need_reset_handler(). 2. Set IDC version only if we are 1st driver to load. 3. Added new function qla4_8xxx_update_idc_reg() to set all idc reg at one place. Signed-off-by:

Add "removable" module parameter to set the "removable" attribute of any subsequently created debug block device. It is a writable driver option, so that you can switch between removable and "fixed" media block devices in between the add_host calls. This is useful for being able to test the different behaviour/required privileges in e. g. the udisks test suite. Signed-off-by:

We always assign a dummy task context to a port in order to address a silicon issue. We have 4 ports per controller. So when idle, there are always exactly 4 TCs "active". The adaptive interrupt coalescing code uses number of active TCs to figure out the coalescing values. However, we never hit "0" TCs because of the 4 dummy TCs. Putting in fix so that we calculate this correctly. Reported-by:

This commit fixes a driver bug for SSP tasks that require task management in the target after they complete in the SCU hardware. The problem was manifested in the function "isci_task_abort_task", which tests to see if the sas_task.lldd_task is non-NULL before allowing task management; this bug would always NULL lldd_task in the SCU I/O completion path even if target management was required, which would prevent task / target manangement from happening. Note that in the case of SATA/STP targets, error recovery is provided by the libata error handler which is why SATA/STP device recovery worked correctly even though SSP handling did not.
