cf8e8658 - arch: Remove Itanium (IA-64) architecture

Thu, 20 Oct 2022 13:54:33 +0000

arch: Remove Itanium (IA-64) architectureThe Itanium architecture is obsolete, and an informal survey [0] revealsthat any residual use of Itanium hardware in production is mostly HP-UXor OpenVMS based. The use of Linux on Itanium appears to be limited toenthusiasts that occasionally boot a fresh Linux kernel to see whetherthings are still working as intended, and perhaps to churn out somedistro packages that are rarely used in practice.None of the original companies behind Itanium still produce or supportany hardware or software for the architecture, and it is listed as'Orphaned' in the MAINTAINERS file, as apparently, none of the engineersthat contributed on behalf of those companies (nor anyone else, for thatmatter) have been willing to support or maintain the architectureupstream or even be responsible for applying the odd fix. The Intelfirmware team removed all IA-64 support from the Tianocore/EDK2reference implementation of EFI in 2018. (Itanium is the originalarchitecture for which EFI was developed, and the way Linux supports itdeviates significantly from other architectures.) Some distros, such asDebian and Gentoo, still maintain [unofficial] ia64 ports, but many havedropped support years ago.While the argument is being made [1] that there is a 'for the commongood' angle to being able to build and run existing projects such as theGrid Community Toolkit [2] on Itanium for interoperability testing, thefact remains that none of those projects are known to be deployed onLinux/ia64, and very few people actually have access to such a system inthe first place. Even if there were ways imaginable in which Linux/ia64could be put to good use today, what matters is whether anyone isactually doing that, and this does not appear to be the case.There are no emulators widely available, and so boot testing Itanium isgenerally infeasible for ordinary contributors. GCC still supports IA-64but its compile farm [3] no longer has any IA-64 machines. GLIBC wouldlike to get rid of IA-64 [4] too because it would permit some overduecode cleanups. In summary, the benefits to the ecosystem of having IA-64be part of it are mostly theoretical, whereas the maintenance overheadof keeping it supported is real.So let's rip off the band aid, and remove the IA-64 arch code entirely.This follows the timeline proposed by the Debian/ia64 maintainer [5],which removes support in a controlled manner, leaving IA-64 in a knowngood state in the most recent LTS release. Other projects will followonce the kernel support is removed.[0] https://lore.kernel.org/all/CAMj1kXFCMh_578jniKpUtx_j8ByHnt=s7S+yQ+vGbKt9ud7+kQ@mail.gmail.com/[1] https://lore.kernel.org/all/0075883c-7c51-00f5-2c2d-5119c1820410@web.de/[2] https://gridcf.org/gct-docs/latest/index.html[3] https://cfarm.tetaneutral.net/machines/list/[4] https://lore.kernel.org/all/87bkiilpc4.fsf@mid.deneb.enyo.de/[5] https://lore.kernel.org/all/ff58a3e76e5102c94bb5946d99187b358def688a.camel@physik.fu-berlin.de/Acked-by: Tony Luck Signed-off-by: Ard Biesheuvel List of files: /linux-6.15/drivers/media/cec/platform/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/media/cec/platform/Kconfig

media: cec: don't select PCI & DMIWhile select would be a great idea for most archs, thiscauses a breakage with s390: "I don't think that's a good idea, as it suddenly enables selecting all PCI drivers on platforms that do not have PCI.

df823a82 - media: cec: rename CEC platform drivers config options

Wed, 15 Apr 2020 10:12:29 +0000

media: cec: rename CEC platform drivers config optionsMost CEC platform drivers are using VIDEO_*_CEC pattern, some withan _HDMI extension too.Well, they're not related to V4L2 support, and we don't reallyneed those big config names. So drop VIDEO_* from them, remove_HDMI (if present) and move CEC to the start.This way, all platform driver options are now CEC_.Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/cec/platform/Kconfig

4be5e864 - media: move CEC platform drivers to a separate directory

media: move CEC platform drivers to a separate directoryAs CEC support doesn't depend on MEDIA_SUPPORT, let'splace the platform drivers outside the media menu.As a side effect, instead of depends on PCI, seco drivercan select it (and DMI).Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab List of files: /linux-6.15/drivers/media/cec/platform/Kconfig
