A page is NOT reusable when at least one of the following is true: 1) allocated when system was under some pressure. (page_is_pfmemalloc) 2) belongs to a different NUMA node than pool->p.nid. To update pool->p.nid users should call page_pool_update_nid(). Holding on to such pages in the pool will hurt the consumer performance when the pool migrates to a different numa node. Performance testing: XDP drop/tx rate and TCP single/multi stream, on mlx5 driver while migrating rx ring irq from close to far numa: mlx5 internal page cache was locally disabled to get pure page pool results. CPU: Intel(R) Xeon(R) CPU E5-2603 v4 @ 1.70GHz NIC: Mellanox Technologies MT27700 Family [ConnectX-4] (100G) XDP Drop/TX single core: NUMA | XDP | Before | After --------------------------------------- Close | Drop | 11 Mpps | 10.9 Mpps Far | Drop | 4.4 Mpps | 5.8 Mpps Close | TX | 6.5 Mpps | 6.5 Mpps Far | TX | 3.5 Mpps | 4 Mpps Improvement is about 30% drop packet rate, 15% tx packet rate for numa far test. No degradation for numa close tests. TCP single/multi cpu/stream: NUMA | #cpu | Before | After -------------------------------------- Close | 1 | 18 Gbps | 18 Gbps Far | 1 | 15 Gbps | 18 Gbps Close | 12 | 80 Gbps | 80 Gbps Far | 12 | 68 Gbps | 80 Gbps In all test cases we see improvement for the far numa case, and no impact on the close numa case. The impact of adding a check per page is very negligible, and shows no performance degradation whatsoever, also functionality wise it seems more correct and more robust for page pool to verify when pages should be recycled, since page pool can't guarantee where pages are coming from.

Add page_pool_update_nid() to be called by page pool consumers when they detect numa node changes. It will update the page pool nid value to start allocating from the new effective numa node. This is to mitigate page pool allocating pages from a wrong numa node, where the pool was originally allocated, and holding on to pages that belong to a different numa node, which causes performance degradation. For pages that are already being consumed and could be returned to the pool by the consumer, in next patch we will add a check per page to avoid recycling them back to the pool and return them to the page allocator.

Grygorii Strashko says: ==================== net: ethernet: ti: introduce new cpsw switchdev based driver Thank you All for review of v6. There are no significant changes in this version, just fixed comments to v6. --- v6 The major change in this version is DT bindings conversation to json-schema, and fixed other comments to v5. Also added patch to clean up ALE on init and netif restart. --- v5 The major part of work done in this iteration is rebasing on top of net-next with XDP series from Ivan Khoronzhuk [3], and enable XDP support in the new CPSW switchdev driver (it was little bit painful ;(). There are mostly no functional changes in new CPSW driver, just few fixes, sync with old driver and cleanups/optimizations. So, I've kept rest of cover letter unchanged. --- This series originally based on work [1][2] done by Ilias Apalodimas <ilias.apalodimas@linaro.org>. This the RFC v5 which introduces new CPSW switchdev based driver which is operating in dual-emac mode by default, thus working as 2 individual network interfaces. The Switch mode can be enabled by configuring devlink driver parameter "switch_mode" to 1/true: devlink dev param set platform/48484000.switch \ name switch_mode value 1 cmode runtime This can be done regardless of the state of Port's netdev devices - UP/DOWN, but Port's netdev devices have to be in UP before joining the bridge to avoid overwriting of bridge configuration as CPSW switch driver completely reloads its configuration when first Port changes its state to UP. When the both interfaces joined the bridge - CPSW switch driver will start marking packets with offload_fwd_mark flag unless "ale_bypass=0". All configuration is implemented via switchdev API. The previous solution of tracking both Ports joined the bridge (from netdevice_notifier) proved to be not correct as changing CPSW switch driver mode required cleanup of ALE table and CPSW settings which happens while second Port is joined bridge and as result configuration loaded by bridge for the first Port became corrupted. The introduction of the new CPSW switchdev based driver (cpsw_new.c) is split on two parts: Part 1 - basic dual-emac driver; Part 2 switchdev support. Such approach has simplified code development and testing alot. And, I hope, it will help with better review. patches #1 - 5: preparation patches which also moves common code to cpsw_priv.c patches #6 - 9: Introduce TI CPSW switch driver based on switchdev and new DT bindings patch #10: new CPSW switchdev driver documentation patch #11: adds DT nodes for new CPSW switchdev driver added for DRA7 SoC patch #12: adds DT nodes for new cpsw switchdev driver for am571x-idk board patch #13: enables build of TI CPSW driver Most of the contents of the previous cover-letter have been added in new driver documentation, so please refer to that for configuration, testing and future work. These patches can be found at (branch contains some additional patches required for testing on top of net-next): https://github.com/grygoriyS/linux.git branch: lkml-5.4-switch-tbd-v7 changes in v7: - patch 2: added check for devm_kmalloc_array() return value - patch 6: fixed comments changes in v6: https://lkml.org/lkml/2019/11/9/108 - DT bindings converted to json-schema - netdev initialization is split on creation and registration. The netdevs registration happens now at the end of the pobe. - reworked cpsw_set_pauseparam() to use PHYlib APIs. - other comments for v5 fixed v5: https://patchwork.kernel.org/cover/11208785/ - rebase on top of net-next with XDP series from Ivan Khoronzhuk [3], and enable XDP support in the new CPSW switchdev driver cpsw driver (tested XDP_DROP only) - sync with old cpsw driver - implement comments from Ivan Khoronzhuk and Rob Herring - fixed "NETDEV WATCHDOG: .." warning after interface after interface UP/DOWN, missed TX wake in cpsw_adjust_link() v4: https://patchwork.kernel.org/cover/11010523/ - finished split of common CPSW code - added devlink support - changed CPSW mode configuration approach: from netdevice_notifier to devlink parameter - refactor and clean up ALE changes which allows to modify VLANs/MDBs entries - added missed support for port QDISC_CBS and QDISC_MQPRIO - the CPSW is split on two parts: basic dual_mac driver and switchdev support - added missed callback .ndo_get_port_parent_id() - reworked ingress frames marking in switch mode (offload_fwd_mark) - applied comments from Andrew Lunn v3: https://lwn.net/Articles/786677/ Changes in v3: - alot of work done to split properly common code between legacy and switchdev CPSW drivers and clean up code - CPSW switchdev interface updated to the current LKML switchdev interface - actually new CPSW switchdev based driver introduced - optimized dual_mac mode in new driver. Main change is that in promiscuous mode P0_UNI_FLOOD (both ports) is enabled in addition to ALLMULTI (current port) instead of ALE_BYPASS. So, port in non promiscuous mode will keep possibility of mcast and vlan filtering. - changed bridge join sequnce: now switch mode will be enabled only when both ports joined the bridge. CPSW will be switched to dual_mac mode if any port leave bridge. ALE table is completly cleared and then refiled while switching to switch mode - this simplidies code a lot, but introduces some limitation to bridge setup sequence: ip link add name br0 type bridge ip link set dev br0 type bridge ageing_time 1000 ip link set dev br0 type bridge vlan_filtering 0 <- disable echo 0 > /sys/class/net/br0/bridge/default_vlan ip link set dev sw0p1 up <- add ports ip link set dev sw0p2 up ip link set dev sw0p1 master br0 ip link set dev sw0p2 master br0 echo 1 > /sys/class/net/br0/bridge/default_vlan <- enable ip link set dev br0 type bridge vlan_filtering 1 bridge vlan add dev br0 vid 1 pvid untagged self - STP tested with vlan_filtering 1/0. To make STP work I've had to set NO_SA_UPDATE for all slave ports (see comment in code). It also required to statically register STP mcast address {0x01, 0x80, 0xc2, 0x0, 0x0, 0x0}; - allowed build both TI_CPSW and TI_CPSW_SWITCHDEV drivers - PTP can be enabled on both ports in dual_mac mode [1] https://patchwork.ozlabs.org/cover/929367/ [2] https://patches.linaro.org/cover/136709/ [3] https://patchwork.kernel.org/cover/11035813/ ==================== Signed-off-by:

Part 1: Introduce basic CPSW dual_mac driver (cpsw_new.c) which is operating in dual-emac mode by default, thus working as 2 individual network interfaces. Main differences from legacy CPSW driver are: - optimized promiscuous mode: The P0_UNI_FLOOD (both ports) is enabled in addition to ALLMULTI (current port) instead of ALE_BYPASS. So, Ports in promiscuous mode will keep possibility of mcast and vlan filtering, which is provides significant benefits when ports are joined to the same bridge, but without enabling "switch" mode, or to different bridges. - learning disabled on ports as it make not too much sense for segregated ports - no forwarding in HW. - enabled basic support for devlink. devlink dev show platform/48484000.switch devlink dev param show platform/48484000.switch: name ale_bypass type driver-specific values: cmode runtime value false - "ale_bypass" devlink driver parameter allows to enable ALE_CONTROL(4).BYPASS mode for debug purposes. - updated DT bindings.

Add bindings for the new TI CPSW switch driver. Comparing to the legacy bindings (net/cpsw.txt): - ports definition follows DSA bindings (net/dsa/dsa.txt) and ports can be marked as "disabled" if not physically wired. - all deprecated properties dropped; - all legacy propertiies dropped which represent constant HW cpapbilities (cpdma_channels, ale_entries, bd_ram_size, mac_control, slaves, active_slave) - TI CPTS DT properties are reused as is, but grouped in "cpts" sub-node - TI Davinci MDIO DT bindings are reused as is, because Davinci MDIO is reused.

A following patches introduce new CPSW switchdev driver which uses common code with legacy CPSW driver. This will introduce build dependency between CPSW switchdev and CPSW legacy drivers related to for_each_slave() and cpsw_slave_index() - they can be compiled both, but only one of them will be not functional depending in Kconfig settings due to duffrences in Slave Ports indexes calculation. To fix this make for_each_slave() local (it's used now only by legacy CPSW driver) and convert cpsw_slave_index() to be a function pointer which is assigned in probe. Driver to probe is defined by DT. Signed-off-by:

geneve RFC (draft-ietf-nvo3-geneve-14) allows a geneve packet to carry multiple geneve opts, so it's necessary for lwtunnel to support adding multiple geneve opts in one lwtunnel route. But vxlan and erspan opts are still only allowed to add one option. With this patch, iproute2 could make it like: # ip r a 1.1.1.0/24 encap ip id 1 geneve_opts 0:0:12121212,1:2:12121212 \ dst 10.1.0.2 dev geneve1 # ip r a 1.1.1.0/24 encap ip id 1 vxlan_opts 456 \ dst 10.1.0.2 dev erspan1 # ip r a 1.1.1.0/24 encap ip id 1 erspan_opts 1:123:0:0 \ dst 10.1.0.2 dev erspan1 Which are pretty much like cls_flower and act_tunnel_key.

On the NXP LS1028A, there are 2 Ethernet links between the Felix switch and the ENETC: - eno2 <-> swp4, at 2.5G - eno3 <-> swp5, at 1G Only one of the above Ethernet port pairs can act as a DSA link for tagging. When adding initial support for the driver, it was tested only on the 1G eno3 <-> swp5 interface, due to the necessity of using PHYLIB initially (which treats fixed-link interfaces as emulated C22 PHYs, so it doesn't support fixed-link speeds higher than 1G). After making PHYLINK work, it appears that swp4 still can't act as CPU port. So it looks like ocelot_set_cpu_port was being called for swp4, but then it was called again for swp5, overwriting the CPU port assigned in the DT. It appears that when you call dsa_upstream_port for a port that is not defined in the device tree (such as swp5 when using swp4 as CPU port), its dp->cpu_dp pointer is not initialized by dsa_tree_setup_default_cpu, and this trips up the following condition in dsa_upstream_port: if (!cpu_dp) return port; So the moral of the story is: don't call dsa_upstream_port for a port that is not defined in the device tree, and therefore its dsa_port structure is not completely initialized (ds->num_ports is still 6).

Ido Schimmel says: ==================== selftests: Add ethtool and scale tests This patch set adds generic ethtool tests and a mlxsw-specific router scale test for Spectrum-2. Patches #1-#2 from Danielle add the router scale test for Spectrum-2. It re-uses the same test as Spectrum-1, but it is invoked with a different scale, according to what it is queried from devlink-resource. Patches #3-#5 from Amit are a re-work of the ethtool tests that were posted in the past [1]. Patches #3-#4 add the necessary library routines, whereas patch #5 adds the test itself. The test checks both good and bad flows with autoneg on and off. The test plan it detailed in the commit message. Last time Andrew and Florian (copied) provided very useful feedback that is incorporated in this set. Namely: * Parse the value of the different link modes from /usr/include/linux/ethtool.h * Differentiate between supported and advertised speeds and use the latter in autoneg tests * Make the test generic and move it to net/forwarding/ instead of being mlxsw-specific [1] https://patchwork.ozlabs.org/cover/1112903/ ==================== Signed-off-by:
