Introduce a new way of specifying how the GSI firmware gets loaded for IPA. Currently, this is indicated by the presence or absence of the Boolean "modem-init" Device Tree property. The new property must have a value--either "self" or "modem"--which indicates whether the AP or modem is the GSI firmware loader, respectively. For legacy systems, the new property will not exist, and the "modem-init" property will be used. For newer systems, the "qcom,gsi-loader" property *must* exist, and must have one of the two prescribed values. It is an error to have both properties defined, and it is an error for the new property to have an unrecognized value. Signed-off-by:

The GSI layer used for IPA requires firmware to be loaded. Currently either the AP or the modem loads the firmware, distinguished by whether the "modem-init" Device Tree property is defined. Some newer systems implement a third option. In preparation for that, encapsulate the code that determines how the GSI firmware gets loaded in a new function, ipa_firmware_loader(). Signed-off-by:

GSI firmware for IPA must be loaded during initialization, either by the AP or by the modem. The loader is currently specified based on whether the Boolean modem-init property is present. Instead, use a new property with an enumerated value to indicate explicitly how GSI firmware gets loaded. With this in place, a third approach can be added in an upcoming patch. The new qcom,gsi-loader property has two defined values: - self: The AP loads GSI firmware - modem: The modem loads GSI firmware The modem-init property must still be supported, but is now marked deprecated. Update the example so it represents the SC7180 SoC, and provide examples for the qcom,gsi-loader, memory-region, and firmware-name properties. Signed-off-by:

Michal Wilczynski says: ==================== Implement devlink-rate API and extend it This patch series implements devlink-rate for ice driver. Unfortunately current API isn't flexible enough for our use case, so there is a need to extend it. Some functions have been introduced to enable the driver to export current Tx scheduling configuration. Pasting justification for this series from commit implementing devlink-rate in ice driver(that is a part of this series): There is a need to support modification of Tx scheduler tree, in the ice driver. This will allow user to control Tx settings of each node in the internal hierarchy of nodes. As a result user will be able to use Hierarchy QoS implemented entirely in the hardware. This patch implemenents devlink-rate API. It also exports initial default hierarchy. It's mostly dictated by the fact that the tree can't be removed entirely, all we can do is enable the user to modify it. For example root node shouldn't ever be removed, also nodes that have children are off-limits. Example initial tree with 2 VF's: [root@fedora ~]# devlink port function rate show pci/0000:4b:00.0/node_27: type node parent node_26 pci/0000:4b:00.0/node_26: type node parent node_0 pci/0000:4b:00.0/node_34: type node parent node_33 pci/0000:4b:00.0/node_33: type node parent node_32 pci/0000:4b:00.0/node_32: type node parent node_16 pci/0000:4b:00.0/node_19: type node parent node_18 pci/0000:4b:00.0/node_18: type node parent node_17 pci/0000:4b:00.0/node_17: type node parent node_16 pci/0000:4b:00.0/node_21: type node parent node_20 pci/0000:4b:00.0/node_20: type node parent node_3 pci/0000:4b:00.0/node_14: type node parent node_5 pci/0000:4b:00.0/node_5: type node parent node_3 pci/0000:4b:00.0/node_13: type node parent node_4 pci/0000:4b:00.0/node_12: type node parent node_4 pci/0000:4b:00.0/node_11: type node parent node_4 pci/0000:4b:00.0/node_10: type node parent node_4 pci/0000:4b:00.0/node_9: type node parent node_4 pci/0000:4b:00.0/node_8: type node parent node_4 pci/0000:4b:00.0/node_7: type node parent node_4 pci/0000:4b:00.0/node_6: type node parent node_4 pci/0000:4b:00.0/node_4: type node parent node_3 pci/0000:4b:00.0/node_3: type node parent node_16 pci/0000:4b:00.0/node_16: type node parent node_15 pci/0000:4b:00.0/node_15: type node parent node_0 pci/0000:4b:00.0/node_2: type node parent node_1 pci/0000:4b:00.0/node_1: type node parent node_0 pci/0000:4b:00.0/node_0: type node pci/0000:4b:00.0/1: type leaf parent node_27 pci/0000:4b:00.0/2: type leaf parent node_27 Let me visualize part of the tree: +---------+ | node_0 | +---------+ | +----v----+ | node_26 | +----+----+ | +----v----+ | node_27 | +----+----+ | |-----------------| +----v----+ +----v----+ | VF 1 | | VF 2 | +----+----+ +----+----+ So at this point there is a couple things that can be done.

Everything auto-loads, and "cat /sys/class/net/eno2/dsa/tagging" shows "ocelot-8021q". Traffic works as well. Furthermore, "echo ocelot-8021q" into the aforementioned sysfs file now auto-loads the driver for it. ==================== Link: https://lore.kernel.org/r/20221115011847.2843127-1-vladimir.oltean@nxp.comSigned-off-by:

Issue a request_module() call when an attempt to change the tagging protocol is made, either by sysfs or by device tree. In the case of ocelot (the only driver for which the default and the alternative tagging protocol are compiled as different modules), the user is now no longer required to insert tag_ocelot_8021q.ko manually. In the particular case of ocelot, this solves a problem where tag_ocelot_8021q.ko is built as module, and this is present in the device tree: &mscc_felix_port4 { dsa-tag-protocol = "ocelot-8021q"; }; &mscc_felix_port5 { dsa-tag-protocol = "ocelot-8021q"; }; Because no one attempts to load the module into the kernel at boot time, the switch driver will fail to probe (actually forever defer) until someone manually inserts tag_ocelot_8021q.ko. This is now no longer necessary and happens automatically. Rename dsa_find_tagger_by_name() to denote the change in functionality: there is now feature parity with dsa_tag_driver_get_by_id(), i.o.w. we also load the module if it's missing.

Vladimir Oltean authored
Currently, dsa_find_tagger_by_name() uses sysfs_streq() which works both with strings that contain \n at the end (echo ocelot > .../dsa/tagging) and with strings that don't (printf ocelot > .../dsa/tagging). There will be a problem once we'll want to construct the modalias string based on which we auto-load the protocol kernel module. If the sysfs buffer ends in a newline, we need to strip it first. This is a preparatory patch specifically for that. Signed-off-by:

Currently, tagging protocol drivers have a modalias of "dsa_tag:id-<number>", where the number is one of DSA_TAG_PROTO_*_VALUE. This modalias makes it possible for the request_module() call in dsa_tag_driver_get() to work, given the input it has - an integer returned by ds->ops->get_tag_protocol(). It is also possible to change tagging protocols at (pseudo-)runtime, via sysfs or via device tree, and this works via the name string of the tagging protocol rather than via its id (DSA_TAG_PROTO_*_VALUE). In the latter case, there is no request_module() call, because there is no association that the DSA core has between the string name and the ID, to construct the modalias. The module is simply assumed to have been inserted. This is actually slightly problematic when the tagging protocol change should take place at probe time, since it's expected that the dependency module should get autoloaded. For this purpose, let's introduce a second modalias, so that the DSA core can call request_module() by name. There is no reason to make the modalias by name optional, so just modify the MODULE_ALIAS_DSA_TAG_DRIVER() macro to take both the ID and the name as arguments, and generate two modaliases behind the scenes.

It's autumn cleanup time, and today's target are modaliases. Michael says that for users of modinfo, "dsa_tag-20" is not the most suggestive name, and recommends a change to "dsa_tag-id-20". Andrew points out that other modaliases have a prefix delimited by colons, so he recommends "dsa_tag:20" instead of "dsa_tag-20". To satisfy both proposals, Florian recommends "dsa_tag:id-20". The modaliases are not stable ABI, and the essential information (protocol ID) is still conveyed in the new string, which request_module() must be adapted to form.

The DSA tagging protocol driver macros are in the public include/net/dsa.h probably because that's also where the DSA_TAG_PROTO_*_VALUE macros are (MODULE_ALIAS_DSA_TAG_DRIVER hinges on those macro definitions). But there is no reason to expose these helpers to <net/dsa.h>. That header is shared between switch drivers (drivers/net/dsa/), tagging protocol drivers (net/dsa/tag_*.c), the DSA core (net/dsa/ sans tag_*.c), and the rest of the world (DSA master drivers, network stack, etc). Too much exposure. On the other hand, net/dsa/dsa_priv.h is included only by the DSA core and by DSA tagging protocol drivers (or IOW, "friend" modules). Also a bit too much exposure - I've contemplated creating a new header which is only included by tagging protocol drivers, but completely separating a new dsa_tag_proto.h from dsa_priv.h is not immediately trivial - for example dsa_slave_to_port() is used both from the fast path and from the control path. So for now, move these definitions to dsa_priv.h which at least hides them from the world. Signed-off-by:

Rasmus Villemoes says: ==================== net: dsa: use more appropriate NET_NAME_* constants for user ports The intention of commit 685343fc ("net: add name_assign_type netdev attribute") was clearly that drivers be switched over one by one to select appropriate NET_NAME_* constants instead of NET_NAME_UNKNOWN. This small series attempts to do that for DSA user ports. This is obviously and intentionally user-visible changes, so there's a small chance that it could lead to a regression. To make it easy to revert either of the "label in DT" and "fallback to eth%d" changes, this is done as a refactoring which shouldn't introduce any functional change (but by itself adds code which looks a little odd, with the two identical assignments in the two branches), followed by changing the constant used in each case in two different patches. ==================== Link: https://lore.kernel.org/r/20221116105205.1127843-1-linux@rasmusvillemoes.dkSigned-off-by:

Many of the drivers which implement ethtool_ops::get_drvinfo() will prints the .driver, .version or .bus_info of struct ethtool_drvinfo. To have a glance of current state, do: $ git grep -W "get_drvinfo(struct" Printing in those three fields is useless because: - since [1], the driver version should be the kernel version (at least for upstream drivers). Arguably, out of tree drivers might still want to set a custom version, but out of tree is not our focus. - since [2], the core is able to provide default values for .driver and .bus_info. In summary, drivers may provide .fw_version and .erom_version, the rest is expected to be done by the core. In struct ethtool_ops doc from linux/ethtool: rephrase field get_drvinfo() doc to discourage developers from implementing this callback. In struct ethtool_drvinfo doc from uapi/linux/ethtool.h: remove the paragraph mentioning what drivers should do. Rationale: no need to repeat what is already written in struct ethtool_ops doc. But add a note that .fw_version and .erom_version are driver defined. Also update the dummy driver and simply remove the callback in order not to confuse the newcomers: most of the drivers will not need this callback function any more.

The rswitch_etha_wait_link_verification() is supposed to return zero on success or negative error codes. Unfortunately it is declared as a bool so the caller treats everything as success. Fixes: 3590918b ("net: ethernet: renesas: Add support for "Ethernet Switch"") Signed-off-by:

The current virtual nci driver is great for testing and fuzzing. But it allows to create at most one "global" device which does not allow to run parallel tests and harms fuzzing isolation and reproducibility. Restructure the driver to allow creation of multiple independent devices. This should be backwards compatible for existing tests. Signed-off-by:

Variable cnt is just being incremented and it's never used anywhere else. The variable and the increment are redundant so remove it. Signed-off-by:
