LinuxLists.cc - [RFC PATCH v2 0/6] Documentation/features: Provide and apply 'features-refresh.sh'

Subject: [RFC PATCH v2 0/6] Documentation/features: Provide and apply 'features-refresh.sh'

Hi,

This series provides the script 'features-refresh.sh', which operates on
the arch support status files, and it applies this script to refresh the
status files in place; previous discussions about this series are at [1].

The series is organized as follows.

- Patch 1/6 adds the script to 'Documentation/features/scripts/'.

- Patch 2/6 presents the results of running the script; this run
also printed the messages

WARNING: 'HAVE_BPF_JIT' is not a valid Kconfig
WARNING: '__HAVE_ARCH_STRNCASECMP' is not a valid Kconfig
WARNING: 'Optimized asm/rwsem.h' is not a valid Kconfig
WARNING: '__HAVE_ARCH_PTE_SPECIAL' is not a valid Kconfig

to standard output.

- Patches 3-6/6 fix each of these warnings.

(Applies on today's mainline.)

Cheers,
Andrea

https://marc.info/?l=linux-kernel&m=152277458614862&w=2

Changes in v2:
- support negation operators in Kconfig (suggested by Ingo Molnar)
- reorder patches 2/6 and 3/6 (suggested by Ingo Molnar)
- add patches 4-6/6 (suggested by Ingo Molnar)

Subject: [RFC PATCH v2 4/6] Documentation/features/locking: Use '!RWSEM_GENERIC_SPINLOCK' as Kconfig for 'rwsem-optimized'

Uses '!RWSEM_GENERIC_SPINLOCK' in place of 'Optimized asm/rwsem.h' as
Kconfig for 'rwsem-optimized': the new Kconfig expresses this feature
equivalently, while also enabling the script 'features-refresh.sh' to
operate on the corresponding arch support status file. Also refreshes
the status matrix by using the script 'features-refresh.sh'.

Subject: [RFC PATCH v2 3/6] Documentation/features/core: Add arch support status files for 'cBPF-JIT' and 'eBPF-JIT'

Commit 6077776b5908e split 'HAVE_BPF_JIT' into cBPF and eBPF variant.
Adds arch support status files for the new variants, and removes the
status file corresponding to 'HAVE_BPT_JIT'. The new status matrices
were auto-generated using the script 'features-refresh.sh'.

Subject: [RFC PATCH v2 1/6] Documentation/features: Add script that refreshes the arch support status files in place

Provides the script:

Documentation/features/scripts/features-refresh.sh

which operates on the arch-support.txt files and refreshes them in place.

This way [1],

"[...] we soft- decouple the refreshing of the entries from the
introduction of the features, while still making it all easy to
keep sync and to extend."
