list_for_each_entry binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ iterator I; expression x; statement S,S1,S2; @@ I(x,...) { <... - if (x == NULL && ...)

When transitioning a QP to the error state, in progress RWQEs need to be marked complete. This also involves releasing the reference count to the memory regions referenced in the SGEs. The locking in the receive packet processing wasn't sufficient to prevent qib_error_qp() from modifying the r_sge state at the same time, thus leading to kernel panics.

Up to now, we have set the number of available user contexts based on the number of hardware contexts which is set according to the number of available CPUs. This was fine since most CPUs had a power of two number of cores and the chip supported 4, 8, or 16 user contexts. Now that some systems have 12 cores, the default isn't optimal and should be set to 12 even though 16 hardware contexts need to be enabled.

There exists a race condition where the app disconnects, which initiates an orderly close (via rdma_fini()), concurrently with an ingress abort condition, which initiates an abortive close operation. Since rdma_fini() must be called without IRQs disabled, the fini can be called after the QP has been transitioned to ERROR. This is ok, but we need to protect against qp->ep getting NULLed.

T4 EQ entries are in multiples of 64 bytes. Currently the RDMA SQ and RQ use fixed sized entries composed of 4 EQ entries for the SQ and 2 EQ entries for the RQ. For optimial latency with small IO, we need to change this so the HW only needs to DMA the EQ entries actually used by a given work request. Implementation: - add wq_pidx counter to track where we are in the EQ. cidx/pidx are used for the sw sq/rq tracking and flow control. - the variable part of work requests is the SGL. Add new functions to build the SGL and/or immediate data directly in the EQ memory wrapping when needed. - adjust the min burst size for the EQ contexts to 64B.

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.
