This patch converts the RX path to use build_skb() for packets larger than copybreak (set to 256 by default). This function makes the first descriptor's page to be the linear part of the sk_buff struct buffer. Also remove the SKB description from the README since most of it no longer relevant and the parts that are left don't add information.

This tweaks several small places to improve the data access in fast path: * Remove duplicates of first_interrupt flag and surround it with WRITE/READ_ONCE macros: The flag is used to detect HW disorders in its interrupt communication with the driver. The flag is set when an interrupt is received and used in the health check function (ena_timer_service()) to help it find irregularities. * Reorder some fields in ena_napi struct to take better advantage of cache access pattern. * Move XDP TX queue number to a variable to save its calculation for every packet. * Use likely in a condition to improve branch prediction The 'first_interrupt' and 'interrupt_masked' flags were moved to reside in the same cache line as the first fields of 'napi' struct. This placement ensures that all memory accessed during upper-half handler reside in the same cacheline (napi_schedule_irqoff() only accesses 'state' and 'poll_list' fields which are at the beginning of napi struct).

Ido Schimmel says: ==================== mlxsw: Various updates This patchset contains various updates for mlxsw. The most significant change is the long overdue removal of the abort mechanism in the first two patches. Patches #1-#2 remove the route abort mechanism. This change is long overdue and explained in detail in the commit message. Patch #3 sets ports down in a few selftests that forgot to do so. Discovered using a BPF tool (WIP) that monitors ASIC resources. Patch #4 fixes an issue introduced by commit 557c4d2f ("selftests: devlink_lib: add check for devlink device existence"). Patches #5-#8 modify the driver to read transceiver module's temperature thresholds using MTMP register (when supported) instead of directly from the module's EEPROM using MCIA register. This is both more reliable and more efficient as now the module's temperature and thresholds are read using one transaction instead of three. ==================== Signed-off-by: David S.

mlxsw_thermal_module_trips_update() is used to update the trip points of the module's thermal zone. Currently, this is done by querying the thresholds from the module's EEPROM via MCIA register. This data does not pass validation and in some cases can be unreliable. For example, due to some problem with transceiver module. Previous patch made it possible to read module's temperature and thresholds via MTMP register. Therefore, extend mlxsw_thermal_module_trips_update() to use the thresholds queried from MTMP, if valid. This is both more reliable and more efficient than current method, as temperature and thresholds are queried in one transaction instead of three. This is significant when working over a slow bus such as I2C.

Provide new function mlxsw_thermal_module_temp_and_thresholds_get() for reading temperature and temperature thresholds by a single operation. The motivation is to reduce the number of transactions with the device which is important when operating over a slow bus such as I2C. Currently, the sole caller of the function is only using it to read the module's temperature. The next patch will also use it to query the module's temperature thresholds.

Currently, module temperature thresholds are obtained from Management Cable Info Access (MCIA) register by specifying the thresholds offsets within module EEPROM layout. This data does not pass validation and in some cases can be unreliable. For example, due to some problem with the module. Add support for a new feature provided by Management Temperature (MTMP) register for sanitization of temperature thresholds values. Extend mlxsw_env_module_temp_thresholds_get() to get temperature thresholds through MTMP field 'max_operational_temperature' - if it is not zero, feature is supported. Otherwise fallback to old method and get the thresholds through MCIA.

In the commit referenced below, a check was added to devlink_lib that asserts the existence of a devlink device referenced by $DEVLINK_DEV. Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that does not exist at the time that devlink_lib is sourced. Thus these tests spuriously fail. Fix this by introducing an override. By setting DEVLINK_DEV to an empty string, the user declares their intention to handle DEVLINK_DEV management on their own. In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it to the correct value right afterwards.

Several tests do not set some ports down as part of their cleanup(), resulting in IPv6 link-local addresses and associated routes not being deleted. These leaks were found using a BPF tool that monitors ASIC resources. Solve this by setting the ports down at the end of the tests.

To check how many routes are installed in hardware, the test runs "ip route" and greps for "offload", which includes routes with state "offload_failed". Till now, this wrong check was not found because after one failure in route insertion, the driver moved to "abort" mode, which means that user cannot try to add more routes. The previous patch removed the abort mechanism and now failed routes are counted as offloaded. Fix this by not considering routes with "offload_failed" flag as offloaded.

Amit Cohen authored
The abort mechanism was introduced in commit 8e05fd71 ("fib: hook IPv4 fib for hardware offload") with the purpose of falling back to software-based routing in case of a route programming error in hardware. The process is irreversible and requires users to reload the offloading driver or reboot the machine. While this approach might make sense in theory, it makes very little sense in practice. In the case of high speed ASICs such as the Spectrum ASIC, the abort mechanism effectively kills the machine upon a non-fatal error such as a route programming error. Such an extreme policy does not belong in the kernel, especially when user space can simply try to reprogram the route following the RTM_NEWROUTE failure notification. Therefore, remove the abort mechanism.

Vladimir Oltean says: ==================== Add NXP SJA1110 support to the sja1105 DSA driver The NXP SJA1110 is an automotive Ethernet switch with an embedded Arm Cortex-M7 microcontroller. The switch has 11 ports (10 external + one for the DSA-style connection to the microcontroller). The microcontroller can be disabled and the switch can be controlled over SPI, a la SJA1105 - this is how this driver handles things. There are some integrated NXP PHYs (100base-T1 and 100base-TX). Their initialization is handled by their own PHY drivers, the switch is only concerned with enabling register accesses to them, by registering two MDIO buses. Changes in v3: - Make sure the VLAN retagging port is enabled and functional - Dropped SGMII PCS from this series Changes in v2: - converted nxp,sja1105 DT bindings to YAML - registered the PCS MDIO bus and forced auto-probing off for all PHY addresses for this bus - changed the container node name for the 2 MDIO buses from "mdio" to "mdios" to avoid matching on the mdio.yaml schema (it's just a container node, not an MDIO bus) - fixed an uninitialized "offset" variable usage in sja1110_pcs_mdio_{read,write} - using the mdiobus_c45_addr macro instead of open-coding that operation ==================== Signed-off-by: David S.

The SJA1110 contains two types of integrated PHYs: one 100base-TX PHY and multiple 100base-T1 PHYs. The access procedure for the 100base-T1 PHYs is also different than it is for the 100base-TX one. So we register 2 MDIO buses, one for the base-TX and the other for the base-T1. Each bus has an OF node which is a child of the "mdio" subnode of the switch, and they are recognized by compatible string.

The SJA1110 is basically an SJA1105 with more ports, some integrated PHYs (100base-T1 and 100base-TX) and an embedded microcontroller which can be disabled, and the switch core can be controlled by a host running Linux, over SPI. This patch contains: - the static and dynamic config packing functions, for the tables that are common with SJA1105 - one more static config tables which is "unique" to the SJA1110 (actually it is a rehash of stuff that was placed somewhere else in SJA1105): the PCP Remapping Table - a reset and clock configuration procedure for the SJA1110 switch. This resets just the switch subsystem, and gates off the clock which powers on the embedded microcontroller. - an RGMII delay configuration procedure for SJA1110, which is very similar to SJA1105, but different enough for us to be unable to reuse it (this is a pattern that repeats itself) - some adaptations to dynamic config table entries which are no longer programmed in the same way. For example, to delete a VLAN, you used to write an entry through the dynamic reconfiguration interface with the desired VLAN ID, and with the VALIDENT bit set to false. Now, the VLAN table entries contain a TYPE_ENTRY field, which must be set to zero (in a backwards-incompatible way) in order for the entry to be deleted, or to some other entry for the VLAN to match "inner tagged" or "outer tagged" packets. - a similar thing for the static config: the xMII Mode Parameters Table encoding for SGMII and MII (the latter just when attached to a 100base-TX PHY) just isn't what it used to be in SJA1105. They are identical, except there is an extra "special" bit which needs to be set. Set it. Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Sergey Ryazanov says: ==================== net: WWAN subsystem improvements While working on WWAN netdev creation support, I notice a few things that could be done to make the wwan subsystem more developer and user friendly. This series implements them. The series begins with a WWAN HW simulator designed simplify testing and make the WWAN subsystem available for a wider audience. The next two patches are intended to make the code a bit more clearer. This is followed by a few patches to make the port device naming more user-friendly. The series is finishes with a set of changes that allow the WWAN AT port to be used with terminal emulation software. All changes were tested with the HW simulator that was introduced in this series, as well as with a Huawei E3372 LTE modem (a CDC-NCM device), which I finally found on my desk. ==================== Signed-off-by: David S.

Purge the rx queue as soon as a user closes the port, just after the port stop callback invocation. This is to prevent feeding a user that will open the port next time with outdated and possibly unrelated data. While at it also remove the odd skb_queue_purge() call in the port device destroy callback. The queue will be purged just before the callback is ivoncated in the wwan_remove_port() function.

It is not unreasonable to assume that users will use terminal emulation software to communicate directly with a WWAN device over the AT port. But terminal emulators will refuse to work with a device that does not support terminal IOCTLs (e.g. TCGETS, TCSETS, TIOCMSET, etc.). To make it possible to interact with the WWAN AT port using a terminal emulator, implement a minimal set of terminal IOCTLs. The implementation is rather stub, no passed data are actually used to control a port behaviour. An obtained configuration is kept inside the port structure and returned back by a request. The latter is done to fool a program that will test the configuration status by comparing the readed back data from the device with earlier configured ones. Tested with fresh versions of minicom and picocom terminal apps. MBIM, QMI and other ports for binary protocols can hardly be considered a terminal device, so terminal IOCTLs are only implemented for the AT port.

It is quite common for a userpace program to fetch the buffered amount of data in the rx queue to avoid the read block. Implement the TIOCINQ ioctl to make the migration to the WWAN port usage smooth. Despite the fact that the read call will return no more data than the size of a first skb in the queue, TIOCINQ returns the entire amount of buffered data (sum of all queued skbs). This is done to prevent the breaking of programs that optimize reading, avoiding it if the buffered amount of data is too small.

Currently, we limit the total ports number to 256. It is quite common for PBX or SMS gateway to be equipped with a lot of modems. In now days, a modem could have 2-4 control ports or even more, what only accelerates the ports exhausing rate. To avoid facing the port number limitation issue reports, increase the limit up the maximum number of minors (i.e. up to 1 << MINORBITS).

At the moment, the port name is allocated based on the parent device name, port id and the port type. Where the port id specifies nothing but the ports registration order and is only used to make the port name unique. Most likely, to configure a WWAN device, the user will look for a port of a specific type (e.g. AT port or MBIM port, etc.). The current naming scheme can make it difficult to find a port of a specific type. Consider a WWAN device that has 3 ports: AT port, MBIM port, and another one AT port. With the global port index, the port names will be: * wwan0p1at * wwan0p2mbim * wwan0p3at To find the MBIM port, user should know in advance the device ports composition (i.e. the user should know that the MBIM port is the 2nd one) or carefully examine the whole ports list. It is not unusual for USB modems to have a different composition, even if they are build on a same chipset. Moreover, some modems able to change the ports composition based on the user's configuration. All this makes port names fully unpredictable. To make naming more user-friendly, remove the global port id and enumerate ports by its type. E.g.: * wwan0p1at -> wwan0at0 * wwan0p2mbim -> wwan0mbim0 * wwan0p3at -> wwan0at1 With this naming scheme, the first AT port name will always be wwanXat0, the first MBIM port name will always be wwanXmbim0, etc. Signed-off-by: Sergey Ryazanov <ryazanov.s.a@gmail.com> Signed-off-by: David S.

Usually a device name is spelled in lowercase, let us follow this practice in the WWAN subsystem as well. The bottom line is that such name is easier to type. To keep the device type attribute contents more natural (i.e., spell abbreviations in uppercase), while making the device name lowercase, turn the port type strings array to an array of structure that contains both the port type name and the device name suffix.

It would be helpful to be able to create/remove devices and ports at run-time to trigger wwan port (un-)register actions without module reloading.

In this mode, the serdes/PHY operates at a serial baud rate of 3.125 Gbps and the PCS data path and GMII interface of the MAC operate at 312.5 MHz instead of 125 MHz. For Intel mGbE, the overclocking of 2.5 times clock rate to support 2.5G is only able to be configured in the BIOS during boot time. Kernel driver has no access to modify the clock rate for 1Gbps/2.5G mode. The way to determined the current 1G/2.5G mode is by reading a dedicated adhoc register through mdio bus. In short, after the system boot up, it is either in 1G mode or 2.5G mode which not able to be changed on the fly. Compared to 1G mode, the 2.5G mode selects the 2500BASEX as PHY interface and disables the xpcs_an_inband. This is to cater for some PHYs that only supports 2500BASEX PHY interface with no autonegotiation. v2: remove MAC supported link speed masking v3: Restructure to introduce intel_speed_mode_2500() to read serdes registers for max speed supported and select the appropritate configuration.
