d1e879ec - wifi: iwlwifi: add iwlmld sub-driver

Sun, 16 Feb 2025 09:42:40 +0000

wifi: iwlwifi: add iwlmld sub-driveriwlwifi is the driver of all Intel wifi devices since 2008.Since then, the hardware has changed a lot, but the firmwareAPI has changed even more. The need to keep one driver thatsupports all those different APIs led us to introduce a newarchitecture circa 2012 which allowed us to keep the sameinterface to the hardware (DMAs, Tx queues, etc...) with anew layer to implement the mid-layer between mac80211 andthe firmware. The first component is called the 'transport'and the latter is called 'operation_mode' a.k.a op_mode.In 2013 we took advantage of the new architecture tointroduce iwlmvm which allowed us to implement the, then,new firmware API. This op_mode supports 7260 and up, thosedevices supports support at least VHT.Since then, wifi evolved and so did the firmware. It becamemuch bigger and took a lot of functionality from the driver.It became increasingly hard to keep the same op_mode for thenewest devices and we experienced frequent regressions onolder devices. In order to avoid those regressions and keepthe code maintainable, we decided it was about time to starta new op_mode.iwlmld is a new op_mode that supports BE200 or newer if thefirmware being used is 97.ucode or newer. If the user hasan older devices or BE200 with .96.ucode, iwlmvm will beloaded. Of course, this op_mode selection is seamless.All the features supported in iwlmvm are supported iniwlmld besides a few seldom used use cases: injection andHotspot 2.0. Those are under work.A few points about the implementation: * iwlmld doesn't have any mutexes, it relies on the wiphy_lock * iwlmld is more "resource oriented": stations, links and interfaces are allocated and freed only after all the relevant flows are completed. * Firmware notifications' sizes are validated in a more structured way.We would love to see this new op_mode merged in 6.15. Thefirmware for this new driver (.97.ucode) is not yet publiclyavailable but it'll be sent very soon.People eager to get an early version of this firmware cancontact Emmanuel at:emmanuel.grumbach@intel.comI've listed the people who directly contributedcode, but many others from various teams havecontributed in other ways.Co-developed-by: Johannes Berg Signed-off-by: Johannes Berg Co-developed-by: Avraham Stern Signed-off-by: Avraham Stern Co-developed-by: Daniel Gabay Signed-off-by: Daniel Gabay Co-developed-by: Emmanuel Grumbach Signed-off-by: Emmanuel Grumbach Co-developed-by: Anjaneyulu Signed-off-by: Anjaneyulu Co-developed-by: Yedidya Benshimol Signed-off-by: Yedidya Benshimol Co-developed-by: Benjamin Berg Signed-off-by: Benjamin Berg Co-developed-by: Shaul Triebitz Signed-off-by: Shaul Triebitz Signed-off-by: Miri Korenblit Link: https://lore.kernel.org/linux-wireless/20250216094321.537988-1-miriam.rachel.korenblit@intel.com/[fix Kconfig, fix api/phy.h includes, SPDX tag and coding style issues, duplicated includes per 0-day robot]Signed-off-by: Johannes Berg List of files: /linux-6.15/drivers/net/wireless/intel/iwlwifi/Kconfig

2da4366f - iwlwifi: mei: add the driver to allow cooperation with CSME

Fri, 12 Nov 2021 06:28:10 +0000

iwlwifi: mei: add the driver to allow cooperation with CSMECSME in two words-----------------CSME stands for Converged Security and Management Engine. It isa CPU on the chipset and runs a dedicated firmware.AMT (Active Management Technology) is one of the applicationsthat run on that CPU. AMT allows to control the platform remotely.Here is a partial list of the use cases:* View the screen of the plaform, with keyboard and mouse (KVM)* Attach a remote IDE device* Have a serial console to the device* Query the state of the platform* Reset / shut down / boot the platformNetworking in CSME------------------For those uses cases, CSME's firmware has an embedded networkstack and is able to use the network devices of the system: LANand WLAN. This is thanks to the CSME's firmware WLAN driver.One can add a profile (SSID / key / certificate) to the CSME's OSand CSME will connect to that profile. Then, one can use the WLANlink to access the applications that run on CSME (AMT is one ofthem). Note that CSME is active during power state and power statetransitions. For example, it is possible to have a KVM sessionopen to the system while the system is rebooting and actuallyconfigure the BIOS remotely over WLAN thanks to AMT.How all this is related to Linux--------------------------------In Linux, there is a driver that allows the OS to talk to theCSME firmware, this driver is drivers/misc/mei. This driveradvertises a bus that allows other kernel drivers or even userspace) to talk to components inside the CSME firmware.In practice, the system advertises a PCI device that allowsto send / receive data to / from the CSME firmware. The meibus drivers in drivers/misc/mei is an abstration on top ofthis PCI device.The driver being added here is called iwlmei and talks to theWLAN driver inside the CSME firmware through the mei bus driver.Note that the mei bus driver only gives bus services, it doesn'tdefine the content of the communication.Why do we need this driver?--------------------------CSME uses the same WLAN device that the OS is expecting to seehence we need an arbitration mechanism. This is what iwlmei isin charge of. iwlmei maintains the communication with the CSMEfirmware's WLAN driver. The language / protocol that is usedbetween the CSME's firmware WLAN driver and iwlmei is OS agnosticand is called SAP which stands for Software Abritration Protocol.With SAP, iwlmei will be able to tell the CSME firmware's WLANdriver:1) Please give me the device.2) Please note that the SW/HW rfkill state change.3) Please note that I am now associated to X.4) Please note that I received this packet.etc...There are messages that go the opposite direction as well:1) Please note that AMT is en/disable.2) Please note that I believe the OS is broken and hence I'll take the device *now*, whether you like it or not, to make sure that connectivity is preserved.3) Please note that I am willing to give the device if the OS needs it.4) Please give me any packet that is sent on UDP / TCP on IP address XX.XX.XX.XX and an port ZZ.5) Please send this packet.etc...Please check drivers/net/wireless/intel/iwlwifi/mei/sap.h for thefull protocol specification.Arbitration is not the only purpose of iwlmei and SAP. SAP alsoallows to maintain the AMT's functionality even when the OS ownsthe device. To connect to AMT, one needs to initiate an HTTPconnection to port 16992. iwlmei will listen to the Rx path andforward (through SAP) to the CSME firmware the data it got. Then,the embedded HTTP server in the chipset will reply to the requestand send a SAP notification to ask iwlmei to send the reply.This way, AMT running on the CSME can still work.In practice this means that all the use cases quoted above (KVM,remote IDE device, etc...) will work even when the OS uses theWLAN device.How to disable all this?---------------------------iwlmei won't be able to do anything if the CSME's networking stackis not enabled. By default, CSME's networking stack is disabled (thisis a BIOS setting).In case the CSME's networking stack is disabled, iwlwifi will justget access to the device because there is no contention with any otheractor and, hence, no arbitration is needed.In this patch, I only add the iwlmei driver. Integration withiwlwifi will be implemented in the next one.Co-Developed-by: Ayala Beker Signed-off-by: Ayala Beker Signed-off-by: Emmanuel Grumbach v2: fix a few warnings raised by the different botsv3: rewrite the commit messagev4: put the debugfs content in a different patchv5: fix a NULL pointer dereference upon DHCP TX if SAP is connected since we now have the required cfg80211 bits in wl-drv-next, add the RFKILL handling patch to this series.v6: change the SAP API to inherit the values from iwl-mei.h removing the need to ensure the values are equal with a BUILD_BUG_ON. This was suggested by Arendv7: * fix a locking issue in case of CSME firmware reset: When the CSME firmware resets, we need to unregister the netdev, first take the mutex, and only then, rely on it being taken. * Add a comment to explain why it is ok to have static variables (iwlmei can't have more than a single instance). * Add a define for 26 + 8 + 8 * Add a define SEND_SAP_MAX_WAIT_ITERATION * make struct const * Reword a bit the Kconfig help message * Ayala added her Signed-off * fixed an RCU annotationv8: do not require ownership upfront, use NIC_OWNER instead.
