bfb57ef0 - rapidio: remove choice for enumeration

Sat, 11 May 2024 00:09:53 +0000

rapidio: remove choice for enumerationThis is the last use of the tristate choice.This choice was introduced a decade ago by commit a11650e11093("rapidio: make enumeration/discovery configurable"). Since then,RAPIDIO_ENUM_BASIC has always been the sole member.There was no need to have this choice block.Signed-off-by: Masahiro Yamada List of files: /linux-6.15/drivers/rapidio/Kconfig

d2b86100 - rapidio: Replace 'select' DMAENGINES 'with depends on'

Tue, 28 Jul 2020 22:19:40 +0000

rapidio: Replace 'select' DMAENGINES 'with depends on'Enabling a whole subsystem from a single driver 'select' is frownedupon and won't be accepted in new drivers, that need to use 'depends on'instead. Existing selection of DMAENGINES will then cause circulardependencies. Replace them with a dependency.Signed-off-by: Laurent Pinchart Acked-by: Randy Dunlap List of files: /linux-6.15/drivers/rapidio/Kconfig

a7f7f624 - treewide: replace '---help---' in Kconfig files with 'help'

Sat, 13 Jun 2020 16:50:22 +0000

treewide: replace '---help---' in Kconfig files with 'help'Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over'---help---'"), the number of '---help---' has been graduallydecreasing, but there are still more than 2400 instances.This commit finishes the conversion. While I touched the lines,I also fixed the indentation.There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---'In order to convert all of them to 1 tab + 'help', I ran thefollowing commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'Signed-off-by: Masahiro Yamada List of files: /linux-6.15/drivers/rapidio/Kconfig

rapidio: consolidate RAPIDIO config entry in drivers/rapidioThere is no good reason to duplicate the RAPIDIO menu in variousarchitectures.

b6e8d4aa - rapidio: add RapidIO channelized messaging driver

Tue, 02 Aug 2016 21:06:25 +0000

rapidio: add RapidIO channelized messaging driverAdd channelized messaging driver to support native RapidIO messagingexchange between multiple senders/recipients on devices that use kernelRapidIO subsystem services.This device driver is the result of collaboration within the RapidIO.orgSoftware Task Group (STG) between Texas Instruments, ProdriveTechnologies, Nokia Networks, BAE and IDT. Additional input wasreceived from other members of RapidIO.org.The objective was to create a character mode driver interface whichexposes messaging capabilities of RapidIO endpoint devices (mports)directly to applications, in a manner that allows the numerous andvaried RapidIO implementations to interoperate.This char mode device driver allows user-space applications to setupmessaging communication channels using single shared RapidIO messagingmailbox.By default this driver uses RapidIO MBOX_1 (MBOX_0 is reserved for use byRIONET Ethernet emulation driver).[weiyj.lk@gmail.com: rapidio/rio_cm: fix return value check in riocm_init()] Link: http://lkml.kernel.org/r/1469198221-21970-1-git-send-email-alexandre.bounine@idt.comLink: http://lkml.kernel.org/r/1468952862-18056-1-git-send-email-alexandre.bounine@idt.comSigned-off-by: Alexandre Bounine Tested-by: Barry Wood Cc: Matt Porter Cc: Aurelien Jacquiot Cc: Andre van Herk Cc: Barry Wood Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/drivers/rapidio/Kconfig

2ec3ba69 - rapidio: convert switch drivers to modules

Wed, 03 Jul 2013 22:08:50 +0000

rapidio: convert switch drivers to modulesRework RapidIO switch drivers to add an option to build them as loadablekernel modules.This patch removes RapidIO-specific vmlinux section and converts switchdrivers to be compatible with LDM driver registration method. To simplifyregistration of device-specific callback routines this patch introducesrio_switch_ops data structure. The sw_sysfs() callback is removed fromthe list of device-specific operations because under the new structure itsfunctions can be handled by switch driver's probe() and remove() routines.If a specific switch device driver is not loaded the RapidIO subsystemcore will use default standard-based operations to configure a switch.Because the current implementation of RapidIO enumeration/discovery methodrelies on availability of device-specific operations for error management,switch device drivers must be loaded before the RapidIOenumeration/discovery starts.This patch also moves several common routines from enumeration/discoverymodule into the RapidIO core code to make switch-specific operationsaccessible to all components of RapidIO subsystem.Signed-off-by: Alexandre Bounine Cc: Matt Porter Cc: Li Yang Cc: Kumar Gala Cc: Andre van Herk Cc: Micha Nelissen Cc: Stef van Os Cc: Jean Delvare Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/drivers/rapidio/Kconfig

a11650e1 - rapidio: make enumeration/discovery configurable

Fri, 24 May 2013 22:55:05 +0000

rapidio: make enumeration/discovery configurableSystems that use RapidIO fabric may need to implement their ownenumeration and discovery methods which are better suitable for needs ofa target application.The following set of patches is intended to simplify process ofintroduction of new RapidIO fabric enumeration/discovery methods.The first patch offers ability to add new RapidIO enumeration/discoverymethods using kernel configuration options. This new configurationoption mechanism allows to select statically linked or modularenumeration/discovery method(s) from the list of existing methods or useexternal module(s).This patch also updates the currently existing enumeration/discoverycode to be used as a statically linked or modular method.The corresponding configuration option is named "Basicenumeration/discovery" method. This is the only one configurationoption available today but new methods are expected to be introducedafter adoption of provided patches.The second patch address a long time complaint of RapidIO subsystemusers regarding fabric enumeration/discovery start sequence. Existingimplementation offers only a boot-time enumeration/discovery start whichrequires synchronized boot of all endpoints in RapidIO network. Whileit works for small closed configurations with limited number ofendpoints, using this approach in systems with large number of endpointsis quite challenging.To eliminate requirement for synchronized start the second patchintroduces RapidIO enumeration/discovery start from user space.For compatibility with the existing RapidIO subsystem implementation,automatic boot time enumeration/discovery start can be configured in byspecifying "rio-scan.scan=1" command line parameter if statically linkedbasic enumeration method is selected.This patch:Rework to implement RapidIO enumeration/discovery method selectioncombined with ability to use enumeration/discovery as a kernel module.This patch adds ability to introduce new RapidIO enumeration/discoverymethods using kernel configuration options. Configuration optionmechanism allows to select statically linked or modularenumeration/discovery method from the list of existing methods or useexternal modules. If a modular enumeration/discovery is selected eachRapidIO mport device can have its own method attached to it.The existing enumeration/discovery code was updated to be used asstatically linked or modular method. This configuration option is named"Basic enumeration/discovery" method.Several common routines have been moved from rio-scan.c to make themavailable to other enumeration methods and reduce number of exportedsymbols.Signed-off-by: Alexandre Bounine Cc: Matt Porter Cc: Li Yang Cc: Kumar Gala Cc: Andre van Herk Cc: Micha Nelissen Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds List of files: /linux-6.15/drivers/rapidio/Kconfig
