2019-04-08drivers: Remove explicit invocations of mmiowb()Will Deacon1-8/+0
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.

2018-08-09qede: Ingress tc flower offload (drop action) support.Manish Chopra1-1/+1
The main motive of this patch is to lay down driver's tc offload infrastructure in place. With these changes tc can offload various supported flow profiles (4 tuples, src-ip, dst-ip, l4 port) for the drop action. Dropped flows statistic is a global counter for all the offloaded flows for drop action and is populated in ethtool statistics as common "gft_filter_drop". Examples - tc qdisc add dev p4p1 ingress tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto tcp dst_ip 192.168.40.200 action drop tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto udp src_ip 192.168.40.100 action drop tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto tcp src_ip 192.168.40.100 dst_ip 192.168.40.200 \ src_port 453 dst_port 876 action drop tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto tcp dst_port 98 action drop Signed-off-by: Manish Chopra <manish.chopra@cavium.com> Signed-off-by: Ariel Elior <ariel.elior@cavium.com> Signed-off-by: David S.

2018-05-17qede: Add build_skb() support.Manish Chopra1-1/+2
This patch makes use of build_skb() throughout in driver's receieve data path [HW gro flow and non HW gro flow]. With this, driver can build skb directly from the page segments which are already mapped to the hardware instead of allocating new SKB via netdev_alloc_skb() and memcpy the data which is quite costly. This really improves performance (keeping same or slight gain in rx throughput) in terms of CPU utilization which is significantly reduced [almost half] in non HW gro flow where for every incoming MTU sized packet driver had to allocate skb, memcpy headers etc. Additionally in that flow, it also gets rid of bunch of additional overheads [eth_get_headlen() etc.] to split headers and data in the skb.

Add support for forwarding via XDP. Once the eBPF is attached, driver would allocate & configure a designated transmission queue meant solely for forwarding packets. Said queue would share the receive-queue's interrupt line, and would have it's own Tx statistics. Infrastructure changes required for this [spread-out through the code]: - Determine the DMA direction of the receive buffers based on the presence of the eBPF program. - Turn the sw Tx ring into a union, as regular/XDP queues have different needs for releasing resources after completion [regular requires the SKB, XDP requires the transmitted page].

2016-11-30qede: Revise state locking schemeMintz, Yuval1-17/+20
As qede utilizes an internal-reload sequence as result of various configuration changes, the netif state wouldn't always accurately describe the status of the configuration. To compensate, we're storing an internal state of the device, which should only be accessed under the qede_lock. This patch fixes and improves several state/lock interactions: - The internal state should only be checked while locked. - While holding lock, it's preferable to check state rather than the netdevice's state. - The reload sequence is not 'atomic' - unload and subsequent load are not in the same critical section. This also add the 'locked' variant for the reload, which would later be used by XDP - useful in the case where the correct sequence is 'lock, check state and re-configure if good', instead of allowing the reload itself to make the decision regarding the configurability of the device.

2016-10-31qede: Fix statistics' strings for Tx/Rx queuesMintz, Yuval1-9/+16
When an interface is configured to use Tx/Rx-only queues, the length of the statistics would be shortened to accomodate only the statistics required per-each queue, and the values would be provided accordingly. However, the strings provided would still contain both Tx and Rx strings for each one of the queues [regardless of its configuration], which might lead to out-of-bound access when filling the buffers as well as incorrect statistics presented.

2016-10-22qede: Fix incorrrect usage of APIs for un-mapping DMA memoryManish Chopra1-2/+2
Driver uses incorrect APIs to unmap DMA memory which were mapped using dma_map_single(). This patch fixes it to use appropriate APIs for un-mapping DMA memory.

2016-10-22qede: Reconfigure rss indirection direction table when rss count is updatedSudarsana Reddy Kalluru1-0/+7
Rx indirection table entries are in the range [0, (rss_count - 1)]. If user reduces the rss count, the table entries may not be in the ccorrect range. Need to reconfigure the table with new rss_count as a basis.
