d818320e - usb: chipidea: make configs for glue drivers visible with EXPERT

Thu, 08 Sep 2022 10:43:35 +0000

usb: chipidea: make configs for glue drivers visible with EXPERTCommit 6a108a14fa35 ("kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT")introduces CONFIG_EXPERT to carry the previous intent of CONFIG_EMBEDDEDand just gives that intent a much better name. That has been clearly a goodand long overdue renaming, and it is clearly an improvement to the kernelbuild configuration that has shown to help managing the kernel buildconfiguration in the last decade.However, rather than bravely and radically just deleting CONFIG_EMBEDDED,this commit gives CONFIG_EMBEDDED a new intended semantics, but keeps itopen for future contributors to implement that intended semantics: A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc).Since then, this CONFIG_EMBEDDED implicitly had two purposes: - It can make even more options visible beyond what CONFIG_EXPERT makes visible. In other words, it may introduce another level of enabling the visibility of configuration options: always visible, visible with CONFIG_EXPERT and visible with CONFIG_EMBEDDED. - Set certain default values of some configurations differently, following the assumption that configuring a kernel build for an embedded system generally starts with a different set of default values compared to kernel builds for all other kind of systems.Considering the first purpose, at the point in time where CONFIG_EMBEDDEDwas renamed to CONFIG_EXPERT, CONFIG_EXPERT already made 130 more optionsbecome visible throughout all different menus for the kernel configuration.Over the last decade, this has gradually increased, so that currently, withCONFIG_EXPERT, roughly 170 more options become visible throughout alldifferent menus for the kernel configuration. In comparison, currently withCONFIG_EMBEDDED enabled, just seven more options are visible, one in x86,one in arm, and five for the ChipIdea Highspeed Dual Role Controller.As the numbers suggest, these two levels of enabling the visibility of evenmore configuration options---beyond what CONFIG_EXPERT enables---neverevolved to a good solution in the last decade. In other words, thisadditional level of visibility of configuration option with CONFIG_EMBEDDEDcompared to CONFIG_EXPERT has since its introduction never become reallyvaluable. It requires quite some investigation to actually understand whatis additionally visible and it does not differ significantly in complexitycompared to just enabling CONFIG_EXPERT. This CONFIG_EMBEDDED---or anyother config to show more detailed options beyond CONFIG_EXPERT---isunlikely to be valuable unless somebody puts significant effort inidentifying how such visibility options can be properly split and creatingclear criteria, when some config option is visible with CONFIG_EXPERT andwhen some config option is visible only with some further option enabledbeyond CONFIG_EXPERT, such as CONFIG_EMBEDDED attempted to do. For now, itis much more reasonable to simply make those additional seven options thatvisible with CONFIG_EMBEDDED, visible with CONFIG_EXPERT, and then removeCONFIG_EMBEDDED. If anyone spends significant effort in structuring thevisibility of config options, they may re-introduce suitable new configoptions simply as they see fit.Make the configs for usb chipidea glue drivers visible when CONFIG_EXPERTis enabled.Signed-off-by: Lukas Bulwahn Link: https://lore.kernel.org/r/20220908104337.11940-5-lukas.bulwahn@gmail.comSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/usb/chipidea/Kconfig
