Documentation/features: Update feature lists for 6.17-rc7

2025-09-25T17:17:56+00:00

It seems that ./Documentation/features/scripts/features-refresh.sh was most recently used in December 2022, with the latest kernel release v6.1-rc7 at that time (see commit 7f2e60ff51ca ("Documentation/features: Update feature lists for 6.1") to update the feature lists in this subdirectory. All further changes to Documentation/features/ since then have probably been done manually, without checking for changes in other architectures and features, that missed to update this part of the documentation. Running ./Documentation/features/scripts/features-refresh.sh now showed seven changes of supported features in various architectures (one in arc, two in parisc, one in riscv, one in openrisc, and two in um), which were not reflected yet in the current documentation. To confirm the sanity of this script's suggested changes, I checked if the commit messages confirm that the features have in fact been added in the following commits: - commit f122668ddcce ("ARC: Add eBPF JIT support") - commit 4800a6215e33 ("parisc: Wire up eBPF JIT compiler") - commit a869b8c29f86 ("riscv: enable mseal sysmap for RV64") - commit 2f681ba4b352 ("um: move thread info into task") - commit 3f17fed21491 ("um: switch to regset API and depend on XSTATE") - commit 7ce8716e2769 ("openrisc: Add HAVE_REGS_AND_STACK_ACCESS_API support") - commit b5ff52be8913 ("parisc: Convert to generic clockevents") So, update all documents to the current state with features-refresh.sh.

Documentation/features: Use loongarch instead of loong

2022-12-05T09:50:12+00:00

The official arch name is LoongArch [1], we should use small letter loongarch instead of loong in Documentation/features, just use the features-refresh.sh to refresh all the related files.

Documentation/features: Update the arch support status files

2022-06-09T15:35:57+00:00

The arch support status files don't match reality as of v5.19-rc1, use the features-refresh.sh to refresh all the arch-support.txt files in place. The main effect is to add entries for the new loong architecture.

Merge branch 'remove-h8300' of git://git.infradead.org/users/hch/misc into asm-generic

2022-04-04T12:42:49+00:00

* 'remove-h8300' of git://git.infradead.org/users/hch/misc: remove the h8300 architecture This is clearly the least actively maintained architecture we have at the moment, and probably the least useful. It is now the only one that does not support MMUs at all, and most of the boards only support 4MB of RAM, out of which the defconfig kernel needs more than half just for .text/.data. Guenter Roeck did the original patch to remove the architecture in 2013 after it had already been obsolete for a while, and Yoshinori Sato brought it back in a much more modern form in 2015. Looking at the git history since the reinstantiation, it's clear that almost all commits in the tree are build fixes or cross-architecture cleanups: $ git log --no-merges --format=%an v4.5.. arch/h8300/ | sort | uniq -c | sort -rn | head -n 12 25 Masahiro Yamada 18 Christoph Hellwig 14 Mike Rapoport 9 Arnd Bergmann 8 Mark Rutland 7 Peter Zijlstra 6 Kees Cook 6 Ingo Molnar 6 Al Viro 5 Randy Dunlap 4 Yury Norov Signed-off-by: Arnd Bergmann

nds32: Remove the architecture

2022-03-07T12:54:59+00:00

The nds32 architecture, also known as AndeStar V3, is a custom 32-bit RISC target designed by Andes Technologies. Support was added to the kernel in 2016 as the replacement RISC-V based V5 processors were already announced, and maintained by (current or former) Andes employees. As explained by Alan Kao, new customers are now all using RISC-V, and all known nds32 users are already on longterm stable kernels provided by Andes, with no development work going into mainline support any more. While the port is still in a reasonably good shape, it only gets worse over time without active maintainers, so it seems best to remove it before it becomes unusable. As always, if it turns out that there are mainline users after all, and they volunteer to maintain the port in the future, the removal can be reverted.

arch: remove unicore32 port

2020-07-01T09:09:13+00:00

The unicore32 port do not seem maintained for a long time now, there is no upstream toolchain that can create unicore32 binaries and all the links to prebuilt toolchains for unicore32 are dead. Even compilers that were available are not supported by the kernel anymore. Guenter Roeck says: I have stopped building unicore32 images since v4.19 since there is no available compiler that is still supported by the kernel. I am surprised that support for it has not been removed from the kernel. Remove unicore32 port. Signed-off-by: Mike Rapoport Acked-by: Arnd Bergmann Acked-by: Guenter Roeck
