ACPI will manage WiFi chip's power state during suspend/resume process on some tablet platforms(such as ASUS T100TA). This is not supported by brcmfmac driver now, and the context of WiFi chip will be damaged after resume. This patch informs ACPI not to manage WiFi chip's power state. Signed-off-by:

This patch implements sendpage support for AF_UNIX SOCK_STREAM sockets. This is also required for a complete splice implementation. The implementation is a bit tricky because we append to already existing skbs and so have to hold unix_sk->readlock to protect the reading side from either advancing UNIXCB.consumed or freeing the skb at the socket receive tail.

Or Gerlitz says: ==================== mlx4: Enable single ported VFs over IB ports This series further enhances the support for mlx4 single ported VFs introduced in 3.15 to work over IB ports too. Just as quick reminder, the ConnectX3 device family exposes one PCI device which serves both ports. This can be non-optimal under virtualization schemes where the admin would like the VF to expose one interface to the VM, etc. Since all the VF interaction with the firmware passes through the PF driver, we can emulate to the VF they have one port, and further create a set of the VFs which act on port1 of the device and another set which acts on port2. ==================== Signed-off-by: -

It's legal for drivers to provide the QP port through the QPC schedule-queue field on the reset-to-init QP state change. Add adjusting of the schedule queue port in the SRIOV wrapper for that operation too. Signed-off-by:

Or Gerlitz authored
Some VF drivers flow set the schedule queue in the QP context but without setting none of OPTPAR_SCHED_QUEUE or OPTPAR_PRIMARY_ADDR_PATH. To allow for such non-modified drivers to function as single ported IB VFs, we must adjust the schedule queue port whenever being set, e.g as currently done for single ported Eth VFs. Signed-off-by:

Or Gerlitz authored
As part of enabling single ported VFs over IB ports we need to handle some of the flows for generting EQ events for VFs which don't come into play under Eth ports. This mainly includes port management events derived from changes of the phyiscal port (lid change, client re-register, down/up, etc), VF pkey table changes and VF guid changes initiated by the IB driver. (1) make sure that events are generated only for VFs sitting on the relevant physical port (under the ALL_SLAVES flow). (2) before generating the event, convert from physical (one or two) to VF port (always equals one). Signed-off-by: -
Or Gerlitz authored
When multiplexling a MAD sent from VF, we should convert the port used by the guest to send the packet to the actual physical port which will be used to transmit the packet, before building the relevant address-handle (AH). This is needed under VPI for single ported VFs, since the code that builds the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we use the port number provided by the guest, it might have different protocol vs. the one this packat has to go from, and hence the result could be wrong. So far, the conversion was done after the AH was built and it worked for single ported Eth VFs which were not enabled under VPI. When adding support for single ported IB VFs and VPI, we hit that.

Single port VFs always provide port = 1 (even if the actual physical port used is port 2). As such, we need to convert the port provided by the VF to the physical port before calling into the firmware. It turns out that the Linux mlx4 VF RoCE driver maintains a copy of the GID table and hence this change became critical only for single ported IB VFs, but it could be needed for other RoCE VF drivers too.

Jesper Dangaard Brouer says: ==================== pktgen: cleanups and introducing new samples/pktgen scripts v3: - Aborted v2 send due it was not generating diff stat (this is a bug in stg-mail, if not in the root directory) v2: address nitpicks from Cong Wang - Remove useless cat's, but keep them for old pgset() - Comment on: Due to pgctrl, cannot use exit code $? from grep - Use arithmetic compare in pktgen_sample03_burst_single_flow.sh This patchset is focused on making pktgen easier to use and better documented. It contains a number of documentation updates and minor changes to pktgen. The major contribution is introduction of common helper function for sample scripts. Instead of the old pgset() function, three new shell functions for configuring the different components of pktgen are introduced: pg_ctrl(), pg_thread() and pg_set(). The new functions correspond to pktgens different components. * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl) * pg_thread() control the kernel threads and binding to devices * pg_set() control setup of individual devices Helpers also provide consistent parameter parsing across the sample scripts. Usage example: ./pktgen_sample01_simple.sh -i eth41 -m 00:12:C0:02:AC:5A -d 192.168.41.2 Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX -i : ($DEV) output interface/device (required) -s : ($PKT_SIZE) packet size -d : ($DEST_IP) destination IP -m : ($DST_MAC) destination MAC-addr -t : ($THREADS) threads to start -c : ($SKB_CLONE) SKB clones send before alloc new SKB -b : ($BURST) HW level bursting of SKBs -v : ($VERBOSE) verbose -x : ($DEBUG) debug These scripts are borrowed from: https://github.com/netoptimizer/network-testing/tree/master/pktgen ==================== Signed-off-by:

This script pktgen_bench_xmit_mode_netif_receive.sh is a benchmark script, which can be used for benchmarking part of the network stack. This can be used for performance improving or catching regression in that area. The script is developed for benchmarking ingress qdisc path, original idea by Alexei Starovoitov. This script don't really need any hardware. This is achieved via the recently introduced stack inject feature "xmit_mode netif_receive".

Add the pktgen samples script pktgen_sample03_burst_single_flow.sh that demonstrates how to acheive maximum performance. If correctly tuned[1] single CPU 10Gbit/s wirespeed small pkts is possible[2] which is 14.88Mpps. The trick is to take advantage of the "burst" feature introduced in commit 38b2cf29 ("net: pktgen: packet bursting via skb->xmit_more").

Add the pktgen samples script pktgen_sample02_multiqueue.sh that demonstrates generating packets on multiqueue NICs. Specifically notice the options "-t" that specifies how many kernel threads to activate. Also notice the flag QUEUE_MAP_CPU, which cause the SKB TX queue to be mapped to the CPU running the kernel thread. For best scalability people are also encourage to map NIC IRQ /proc/irq/*/smp_affinity to CPU number. Usage example with "-t" 4 threads and help: ./pktgen_sample02_multiqueue.sh -i eth4 -m 00:1B:21:3C:9D:F8 -t 4 Usage: ./pktgen_sample02_multiqueue.sh [-vx] -i ethX -i : ($DEV) output interface/device (required) -s : ($PKT_SIZE) packet size -d : ($DEST_IP) destination IP -m : ($DST_MAC) destination MAC-addr -t : ($THREADS) threads to start -c : ($SKB_CLONE) SKB clones send before alloc new SKB -b : ($BURST) HW level bursting of SKBs -v : ($VERBOSE) verbose -x : ($DEBUG) debug Removing pktgen.conf-2-1 and pktgen.conf-2-2 as these examples should be covered now.

Add the first basic pktgen samples script pktgen_sample01_simple.sh, which demonstrates the a simple use of the helper functions. Removing pktgen.conf-1-1 as that example should be covered now.

Preparing for removing existing samples/pktgen/ scripts, and replacing these with easier to use samples. This commit provides two helper shell files, that can be "included" by shell source'ing. Namely "functions.sh" and "parameters.sh". The parameters.sh file support easy and consistant parameter parsing across the sample scripts. Usage example is printed on errors. The functions.sh file provides, three new shell functions for configuring the different components of pktgen: pg_ctrl(), pg_thread() and pg_set(). A slightly improved version of the old pgset() function is also provided for backwards compat. The new functions correspond to pktgens different components. * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl) * pg_thread() control the kernel threads and binding to devices * pg_set() control setup of individual devices These changes are borrowed from: https://github.com/netoptimizer/network-testing/tree/master/pktgenSigned-off-by:

Giving /proc/net/pktgen/pgctrl an invalid command just returns shell success and prints a warning in dmesg. This is not very useful for shell scripting, as it can only detect the error by parsing dmesg. Instead return -EINVAL when the command is unknown, as this provides userspace shell scripting a way of detecting this. Also bump version tag to 2.75, because (1) reading /proc/net/pktgen/pgctrl output this version number which would allow to detect this small semantic change, and (2) because the pktgen version tag have not been updated since 2010.
