IB/qib: Use request_firmware() to load SD7220 firmware

2010-07-08T20:27:05+00:00

Extract the microcode for the QLogic QLE7220 series IB HCA and use the
kernel microcode request facility to load the microcode.  This
supports Debian Linux's requirements to separate microcode which
doesn't have open source code available from the device driver.

IB/qib: Clean up properly if qib_init() fails

2010-07-06T21:14:04+00:00

If qib_init() fails, the driver fails to free memory, unregister
device files, and unregister with the PCIe framework. The driver will
unload without error but a subsequent driver load will cause the
system to panic.  This was found by changing the 7220 code to load the
serdes microcode separately and not installing the microcode file.

IB/qib: Completion queue callback needs to be single threaded

2010-07-06T21:13:58+00:00

Workqueues aren't exactly equivalent to tasklets since the callback
function may be called from multiple CPUs before the callback returns.
This causes completion notification callbacks to have MT bugs since
they weren't expecting this behavior. The fix is to use a single
threaded work queue.

IB/qib: Clear 6120 hardware error register

2010-07-06T21:13:40+00:00

The hardware error register needs to be cleared or another interrupt
will be generated, thus causing an infinite loop.  This is a
regression introduced when removing debug output.

IB/qib: Clear eager buffer memory for each new process

2010-07-06T21:13:21+00:00

The eager buffers are not being cleared before being mmapped into a
new user address space.  This is a potential security risk and should
be fixed.  Note that the eager header queue is already being cleared.

IB/qib: Mask hardware error during link reset

2010-07-06T21:13:20+00:00

The HCA checks for certain hardware errors which can be falsely
triggered when the IB link is reset. The fix is to mask them rather
than report them.

IB/qib: Don't mark VL15 bufs as WC to avoid a rare 7322 chip problem

2010-07-06T21:13:20+00:00

Don't set write combining via PAT on the VL15 buffers to avoid a rare
problem with unaligned writes from interrupt-flushed store buffers.
