drivers: Remove explicit invocations of mmiowb()

2019-04-08T11:01:02+00:00

mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

qed: Add infrastructure for error detection and recovery

2019-01-28T18:58:41+00:00

This patch adds the detection and handling of a parity error ("process kill event"), including the update of the protocol drivers, and the prevention of any HW access that will lead to device access towards the host while recovery is in progress. It also provides the means for the protocol drivers to trigger a recovery process on their decision.

qed: Expose the doorbell overflow recovery mechanism to the protocol drivers

2018-11-30T21:45:13+00:00

Most of the doorbelling entities are outside of the core module. L2 queues, Roce queues, iscsi and fcoe all need to register. Make the APIs available for these drivers. Signed-off-by: Ariel Elior Signed-off-by: Michal Kalderon Signed-off-by: Tomer Tayar Signed-off-by: David S. Miller

qed: Add doorbell overflow recovery mechanism

2018-11-30T21:45:12+00:00

Add the database used to register doorbelling entities, and APIs for adding and deleting entries, and logic for traversing the database and doorbelling once on behalf of all entities.
