Alex Elder says: ==================== net: ipa: more configuration data updates This series starts with two patches that should have been included in an earlier series. With these in place, QSB settings are programmed from information found in the data files rather than being embedded in code. Support is then added for reprenting another QSB property (supported for IPA v4.0+). The third patch updates the definition of the sequencer type used for an endpoint. Previously a set of 2-byte symbols with fairly long names defined the sequencer type, but now those are broken into 1-byte halves whose names are a little more informative. The fourth patch moves the sequencer type definition so it only applies to TX endpoints (they aren't valid for RX endpoints). And the last makes some minor documentation updates. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

We only program the sequencer type for TX endpoints. So move the definition of the sequencer type fields into the TX-specific portion of the endpoint configuration data. There's no need to maintain this in the IPA structure; we can extract it from the configuration data it points to in the one spot it's needed. We previously specified the sequencer type for RX endpoints with INVALID values. These are no longer needed, so get rid of them. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

An IPA endpoint has a sequencer that must be configured based on how the endpoint is to be used. Currently the IPA code programs the sequencer type by splitting a value into four 4-bit nibbles. Doing that doesn't really add much value, and regardless, a better way of splitting the sequencer type is into two halves--the lower byte describing how normal packet processing is handled, and the next byte describing information about processing replicas. So split the sequencer type into two sub-parts: the sequencer type and the replication sequencer type. Define the values supported for the "main" sequencer type, and define the values supported for the replication part separately. In addition, the sequencer type names are quite verbose, encoding what the type includes, but also what it *excludes*. Rename the sequencer types in a way that mainly describes the number of passes that a packet takes through the IPA processing pipeline, and how many of those passes end by supplying the processed packet to the microprocessor. The result expands the supported types beyond what is required for now, but simplifies the way these are defined. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

Starting with IPA v4.0, a limit is placed on the number of bytes outstanding in a transaction, to reduce latency. The limit is imposed only if this value is non-zero. We don't use a non-zero value for SC7180, but newer versions of IPA do. Prepare for that by allowing a programmed value to be specified in the platform configuration data.

I was working on a syzbot issue, claiming one device could not be dismantled because its refcount was -1 unregister_netdevice: waiting for sit0 to become free. Usage count = -1 It would be nice if syzbot could trigger a warning at the time this reference count became negative. This patch adds CONFIG_PCPU_DEV_REFCNT options which defaults to per cpu variables (as before this patch) on SMP builds. v2: free_dev label in alloc_netdev_mqs() is moved to avoid a compiler warning (-Wunused-label), as reported by kernel test robot <lkp@intel.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

Alex Elder says: ==================== net: ipa: update configuration data Each IPA version has a "data" file defining how various things are configured. This series gathers a few updates to this information: - The first patch makes all configuration data constant - The second fixes an incorrect (but seemingly harmless) value - The third simplifies things a bit by using implicit zero initialization for memory regions that are empty - The fourth adds definitions for memory regions that exist but are not yet used - The fifth use configuration data rather than conditional code to set some bus parameters ====================

There are several memory regions that are defined starting with IPA v4.0, but which were not used for the SC7180 SoC (IPA v4.2). Even though they're not used (yet), define them so they are ready to be used for SoCs when they become supported. There are two QUOTA statistics memory regions, one for the modem and one for the AP. Define distinct names for these regions, and get rid of the definition of IPA_MEM_STATS_QUOTA. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>

The AP_HEADER memory region for both the SDM845 and SC7180 SoCs has zero size, and has no canaries. Defining an offset for such a zero-length region is not meaningful, so it's better not to define it at all. The size of this region is used in the code, but its value will still be zero because the memory regions are defined in statically initialized memory. For the SC7180, the STATS_DROP memory region has a zero size and no canaries as well. These regions are the only place where a zero-sized region is defined despite having no canaries. Remove them.

Here is what Vladimir says about it: at803x_aneg_done() keeps the aneg reporting as "not done" even when the copper-side link was reported as up, but the in-band autoneg has not finished. That was the _intended_ behavior when that code was introduced, and Heiner have said about it [1]: | That's not nice from the PHY: | It signals "link up", and if the system asks the PHY for link details, | then it sheepishly says "well, link is *almost* up". If the specification of phy_aneg_done behavior does not include in-band autoneg (and it doesn't), then this piece of code does not belong here. The fact that we can no longer trigger this code from phylib is yet another reason why it fails at its intended (and wrong) purpose and should be removed. Removing the SGMII link check, would just keep the call to genphy_aneg_done(), which is also the fallback. Thus we can just remove at803x_aneg_done() altogether.

When using short intervals e.g. below one millisecond, large packets won't be transmitted at all. The software implementations checks whether the packet can be fit into the remaining interval. Therefore, it takes the packet length and the transmission speed into account. That is correct. However, for large packets it may be that the transmission time exceeds the interval resulting in no packet transmission. The same situation works fine with hardware offloading applied. The problem has been observed with the following schedule and iperf3: |tc qdisc replace dev lan1 parent root handle 100 taprio \ | num_tc 8 \ | map 0 1 2 3 4 5 6 7 0 1 2 3 4 5 6 7 \ | queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 \ | base-time $base \ | sched-entry S 0x40 500000 \ | sched-entry S 0xbf 500000 \ | clockid CLOCK_TAI \ | flags 0x00 [...] |root@tsn:~# iperf3 -c 192.168.2.105 |Connecting to host 192.168.2.105, port 5201 |[ 5] local 192.168.2.121 port 52610 connected to 192.168.2.105 port 5201 |[ ID] Interval Transfer Bitrate Retr Cwnd |[ 5] 0.00-1.00 sec 45.2 KBytes 370 Kbits/sec 0 1.41 KBytes |[ 5] 1.00-2.00 sec 0.00 Bytes 0.00 bits/sec 0 1.41 KBytes After debugging, it seems that the packet length stored in the SKB is about 7000-8000 bytes. Using a 100 Mbit/s link the transmission time is about 600us which larger than the interval of 500us. Therefore, segment the SKB into smaller chunks if the packet is too big. This yields similar results than the hardware offload: |root@tsn:~# iperf3 -c 192.168.2.105 |Connecting to host 192.168.2.105, port 5201 |- - - - - - - - - - - - - - - - - - - - - - - - - |[ ID] Interval Transfer Bitrate Retr |[ 5] 0.00-10.00 sec 48.9 MBytes 41.0 Mbits/sec 0 sender |[ 5] 0.00-10.02 sec 48.7 MBytes 40.7 Mbits/sec receiver Furthermore, the segmentation can be skipped for the full offload case, as the driver or the hardware is expected to handle this.
