2021-05-17mlxsw: Remove Mellanox SwitchX-2 ASIC supportAmit Cohen
Initial support for the Mellanox SwitchX-2 ASIC was added in July 2015. Since then all development efforts shifted towards the Mellanox Spectrum ASICs and development of this driver stopped beside trivial fixes and refactoring. Therefore, the driver does not support any switch offloads and simply traps all traffic to the CPU, rendering it irrelevant for deployment. In addition, support for this ASIC was dropped by Mellanox a few years ago. Given the driver is not used by any users and that there is no intention of investing in its development, remove it from the kernel.

The commit cited below moved firmware flashing functionality from mlxsw_spectrum to mlxsw_core, but did not adjust the Kconfig dependencies. This makes it possible to have mlxsw_core as built-in and mlxfw as a module.

2019-07-01mlxsw: spectrum: PTP: Support timestamping on Spectrum-1Petr Machata
On Spectrum-1, timestamps arrive through a pair of dedicated events: MLXSW_TRAP_ID_PTP_ING_FIFO and _EGR_FIFO. The payload delivered with those traps is contents of the timestamp FIFO at a given port in a given direction. Add a Spectrum-1-specific handler for these two events which decodes the timestamps and forwards them to the PTP module. Add a function that parses a packet, dispatching to ptp_classify_raw(), and decodes PTP message type, domain number, and sequence ID. Add a new mlxsw dependency on the PTP classifier. Add helpers that can store and retrieve unmatched timestamps and SKBs to the hash table added in a preceding patch. Add the matching code itself: upon arrival of a timestamp or a packet, look up the corresponding unmatched entry, and match it up. If there is none, add a new unmatched entry. This logic is the same on ingress as on egress. Packets and timestamps that never matched need to be eventually disposed of. A garbage collector added in a follow-up patch will take care of that. Since currently all this code is turned off, no crud will accumulate in the hash table.

2018-07-25mlxsw: spectrum_acl: Implement common eRP coreIdo Schimmel
When rules are inserted into the A-TCAM they are associated with a mask, which is part of the lookup key: { masked key, mask ID, region ID }. These masks are called rule patterns (RP) and the aggregation of several masks into one (to be introduced in follow-up patch sets) is called an extended RP (eRP). When a packet undergoes a lookup in an ACL region it is masked by the current set of eRPs used by the region, looking for an exact match. Eventually, the rule with the highest priority is picked. These eRPs are stored in several global banks to allow for lookup to occur using several eRPs simultaneously. At first, an ACL region will only require a single mask - upon the insertion of the first rule. In this case, the region can use the "master RP" which is composed by OR-ing all the masks used by the region. This mask is a property of the region and thus there is no need to use the above mentioned banks. At some point, a second mask will be needed. In this case, the region will need to allocate an eRP table from the above mentioned banks and insert its masks there. >From now on, upon lookup, the eRP table used by the region will be fetched from the eRP banks - using {eRP bank, Index within the bank} - and the eRPs present in the table will be used to mask the packet. Note that masks with consecutive indexes are inserted into consecutive banks. When rules are deleted and a region only needs a single mask once again it can free its eRP table and use the master RP. The above logic is implemented in the eRP core and represented using the following state machine: +------------+ create mask - as master RP +---------------+ | +--------------------------------> | | no masks | | single mask | | <--------------------------------+ | +------------+ delete mask +-----+--^------+ | | | | create mask - | | delete mask - create mask transition to use eRP | | transition to +--------+ table | | use master RP | | | | | | | | +----v--------+----+ create mask +----v--+-----+ | <-------------------------------+ | | multiple masks | | two masks | | +-------------------------------> | +------------------+ delete mask - if two +-------------+ remaining The code that actually configures rules in the A-TCAM will interface with the eRP core by getting or putting an eRP based on the required mask used by the rule.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

2018-03-12mlxsw: spectrum: Don't depend on ip_gre and ip6_grePetr Machata
mlxsw_spectrum supports offloading of a tc action mirred egress mirror to a gretap or an ip6gretap netdevice, which necessitates calls to functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about picking which modules are absolutely required, and therefore the better approach is to make mlxsw_spectrum tolerant of absence of one or both of the GRE flavors. Hence rework the NET_IPGRE and IPV6_GRE dependencies to just guard matching modularity, and hide the corresponding code in spectrum_span.c in an #if IS_ENABLED. Mark mlxsw_sp_span_entry_tunnel_parms_common as maybe unused, to muffle warnings if neither GRE flavor is selected, which seems cleaner than introducing a composite #if.

2018-02-27mlxsw: spectrum_span: Support mirror to gretapPetr Machata
When a user requests mirror from a mlxsw physical port (possibly based on an ACL match) to a gretap netdevice, the driver needs to resolve the request to a particular physical port that the mirrored packets will egress through, and a suite of configuration keys (importantly, IP and MAC addresses). That means calling into routing and neighbor kernel code to simulate the decisions made by the system for packets passing through a gretap netdevice.

2017-08-03mlxsw: spectrum_router: Add support for IPv6 routes addition / deletionIdo Schimmel
Allow directly connected and remote unicast IPv6 routes to be programmed to the device's tables. As with IPv4, identical routes - sharing the same destination prefix - are ordered in a FIB node according to their table ID and then the metric. While the kernel doesn't share the same trie for the local and main table, this does happen in the device, so ordering according to table ID is needed. Since individual nexthops can be added and deleted in IPv6, each FIB entry stores a linked list of the rt6_info structs it represents. Upon the addition or deletion of a nexthop, a new nexthop group is allocated according to the new configuration and the old one is destroyed. Identical groups aren't currently consolidated, but will be in a follow-up patchset.

2016-10-28mlxsw: Move PCI id table definitions into driver modulesJiri Pirko
So far, mlxsw_pci.ko is the module that registers PCI table for all drivers (spectrum and switchx2). That is problematic for example with dracut. Since mlxsw_spectrum.ko and mlxsw_switchx2.ko are loaded dynamically from within mlxsw_core.ko, dracut does not have track of them and avoids them from being included in initramfs. So make this in an ordinary way and define the PCI tables in individual driver modules, so it can be properly loaded and included in dracut initramfs image. As a side effect, this patch could remove no longer necessary driver "kind" strings which were used to link PCI ids with individual mlxsw drivers.

2015-07-30mlxsw: Introduce Mellanox SwitchX-2 ASIC supportJiri Pirko
Benefit from the previously introduced Mellanox Switch infrastructure and add driver for SwitchX-2 ASIC. Note that this driver is very simple now. It implements bare minimum for getting device to work on slow-path. Fast-path offload functionality is going to be added soon.

2015-07-30mlxsw: Introduce Mellanox switch driver coreJiri Pirko
Add core components of Mellanox switch driver infrastructure. Core infrastructure is designed so that it can be used by multiple bus drivers (PCI now, I2C and SGMII are planned to be implemented in the future). Multiple switch kind drivers can be registered as well. This core serves as a glue between buses and drivers.
