Add arch support matrices for more than 40 generic kernel features
that need per architecture support.
Each feature has its own directory under Documentation/features/feature_name/,
and the arch-support.txt file shows its current arch porting status.
For example, lockdep support is shown the following way:
triton:~/tip> cat Documentation/features/lockdep/arch-support.txt
#
# Feature name: lockdep
# Kconfig: LOCKDEP_SUPPORT
# description: arch supports the runtime locking correctness debug facility
#
-----------------------
| arch |status|
-----------------------
| alpha: | TODO |
| arc: | ok |
| arm: | ok |
| arm64: | ok |
| avr32: | ok |
| blackfin: | ok |
| c6x: | TODO |
| cris: | TODO |
| frv: | TODO |
| hexagon: | ok |
| ia64: | TODO |
| m32r: | TODO |
| m68k: | TODO |
| metag: | ok |
| microblaze: | ok |
| mips: | ok |
| mn10300: | TODO |
| nios2: | TODO |
| openrisc: | TODO |
| parisc: | TODO |
| powerpc: | ok |
| s390: | ok |
| score: | ok |
| sh: | ok |
| sparc: | ok |
| tile: | ok |
| um: | ok |
| unicore32: | ok |
| x86: | ok |
| xtensa: | ok |
-----------------------
For generic kernel features that need architecture support, the
arch-support.txt file in each feature directory shows the arch
support matrix, for all upstream Linux architectures.
The meaning of entries in the tables is:
| ok | # feature supported by the architecture
|TODO| # feature not yet supported by the architecture
| .. | # feature cannot be supported by the hardware
This directory structure can be used in the future to add other
files - such as porting guides, testing description, etc.
The Documentation/features/ hierarchy may also include generic
kernel features that works on every architecture, in that case
the arch-support.txt file will list every architecture as
supported.
To list an architecture's unsupported features, just do something
like:
$ git grep -lE 'x86.*TODO' Documentation/features/*/arch-support.txt
Documentation/features/arch-tick-broadcast/arch-support.txt
Documentation/features/strncasecmp/arch-support.txt
which prints the list of features not yet supported by the
architecture.
