283e6f5a - net: wwan: make debugfs optional

Tue, 07 Dec 2021 09:21:40 +0000

net: wwan: make debugfs optionalDebugfs interface is optional for the regular modem use. Some distrosand users will want to disable this feature for security or kernelsize reasons. So add a configuration option that allows to completelydisable the debugfs interface of the WWAN devices.A primary considered use case for this option was embedded firmwares.For example, in OpenWrt, you can not completely disable debugfs, as alot of wireless stuff can only be configured and monitored with thedebugfs knobs. At the same time, reducing the size of a kernel andmodules is an essential task in the world of embedded software.Disabling the WWAN and IOSM debugfs interfaces allows us to save 50K(x86-64 build) of space for module storage. Not much, but alreadyconsiderable when you only have 16MB of storage.So it is hard to just disable whole debugfs. Users need some finegrained set of options to control which debugfs interface is importantand should be available and which is not.The new configuration symbol is enabled by default and is hidden underthe EXPERT option. So a regular user would not be bothered by anotherone configuration question. While an embedded distro maintainer will beable to a little more reduce the final image size.Signed-off-by: Sergey Ryazanov Reviewed-by: Leon Romanovsky Reviewed-by: Loic Poulain Acked-by: M Chetan Kumar Signed-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/wwan/iosm/Makefile

cf90098d - net: wwan: iosm: move debugfs knobs into a subdir

Tue, 07 Dec 2021 09:21:39 +0000

net: wwan: iosm: move debugfs knobs into a subdirThe modem traces collection is a device (and so driver) specific option.Therefore, move the related debugfs files into a driver-specificsubdirectory under the common per WWAN device directory.Signed-off-by: Sergey Ryazanov Reviewed-by: Loic Poulain Acked-by: M Chetan Kumar Signed-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/wwan/iosm/Makefile

00ef3256 - net: wwan: iosm: device trace collection using relayfs

Sat, 20 Nov 2021 16:21:55 +0000

net: wwan: iosm: device trace collection using relayfsThis patch brings in support for device trace collection.It implements relayfs interface for pushing device tracefrom kernel space to user space.Driver gets the debugfs base directory associated to WWANDevice and creates trace_control and trace debugfs fordevice tracing. Both trace_control & trace debugfs arecreated under /sys/kernel/debug/wwan/wwan0/.In order to collect device trace on trace0 interface, userneed to write 1 to trace_ctl interface.Signed-off-by: M Chetan Kumar Signed-off-by: David S.

net: wwan: iosm: firmware flashing and coredump collectionThis patch brings-in support for M.2 7560 Device firmware flashing &coredump collection using devlink.- Driver Registers with Devlink framework.- Register devlink params callback for configuring device params required in flashing or coredump flow.- Implements devlink ops flash_update callback that programs modem firmware.- Creates region & snapshot required for device coredump log collection.On early detection of device in boot rom stage. Driver registers withDevlink framework and establish transport channel for PSI (Primary SignedImage) injection. Once PSI is injected to device, the device executionstage details are read to determine whether device is in flash orexception mode. The collected information is reported to devlink userspace application & based on this informationi, application proceeds witheither modem firmware flashing or coredump collection.Signed-off-by: M Chetan Kumar Signed-off-by: David S.
