2For generic kernel features that need architecture support, the
3arch-support.txt file in each feature directory shows the arch
4support matrix, for all upstream Linux architectures.
5
6The meaning of entries in the tables is:
7
8 | ok | # feature supported by the architecture
9 |TODO| # feature not yet supported by the architecture
10 | .. | # feature cannot be supported by the hardware
