We could use kvmalloc_array instead of the kmalloc and __vmalloc combination. After this we don't need to include linux/vmalloc.h Signed-off-by:

We observed multiple times on our Lustre OSS servers that when the system memory is fragmented, kmalloc() in create_kernel_qp() could fail order 4/5 allocations while we still have many free pages. Switch to kvmalloc_array() to allow the operation to contine. Signed-off-by:

The current timeout logic for Control Queue-Pair (CQP) OPs does not take into account whether CQP makes progress but rather blindly waits for a large timeout value, 100000 jiffies for the completion event. Improve this by setting the timeout based on whether the CQP is making progress or not. If the CQP is hung, the timeout will happen sooner, in 5000 jiffies. Each time the CQP progress is detetcted, the timeout extends by 5000 jiffies. Signed-off-by:

There is a mixture of mutex and spinlocks to protect receive context (rcd/uctxt) information. This is not used consistently. Use the mutex to protect device receive context information only. Use the spinlock to protect sub context information only. Protect access to items in the rcd array with a spinlock and reference count. Remove spinlock around dd->rcd array cleanup. Since interrupts are disabled and cleaned up before this point, this lock is not useful. Reviewed-by:

Michael J. Ruhl authored
The rcd array can be accessed from user context or during interrupts. Protecting this with a mutex isn't a good idea because the mutex should not be used from an IRQ. Protect the allocation and freeing of rcd array elements with a spinlock. Reviewed-by:

When DC is shut down (by e.g. disconnecting the cable), the driver should use host_link_state to get port's current physical state. This is due to the fact that physical state is read from DC's CSRs and when DC is shut down and state is changed, its registers are not impacted. Reviewed-by:

Enables multiple Interrupt vectors. Driver is requesting the max MSIX vectors based on the number of online cpus and creates upto 9 MSIx vectors (1 for control path and 8 for data path). A tasklet is created for each of these vectors. NQs are assigned to CQs in round robin fashion. This patch also adds IRQ affinity hint for the MSIX vector of each NQ. Signed-off-by:
