RISC-V With Linux 6.15 Adds Support For BFloat16 "BF16" Instructions

([RISC-V] 2 Hours Ago Linux 6.15 RISC-V)


Merged on Friday for the nearly-over [1]Linux 6.15 merge window were the RISC-V CPU architecture updates for this next kernel release.

RISC-V with Linux 6.15 brings build improvements thanks to a re-architecting of the Kconfig build system options around RISC-V for selecting sub-architecture features.

For the Linux 6.15 kernel with RISC-V there is also support for building relocatable non-MMU kernels, support for huge PFNMAPS to improve TLB utilization, support for runtime constants, new RISC-V instructions supported, and a variety of fixes.

RISC-V in this next Linux kernel version adds support for a number of newer instructions including bfloat16, Zicbom, Zaamo, Zalrsc, Zicntr, and Zihpm. Yes, RISC-V is finally ready to go with its BFloat16 precision floating-point ISA support. The BF16 extensions were ratified for the RISC-V spec and now prepped for the necessary Linux kernel bits.

The full list of RISC-V architecture changes for the Linux 6.15 merge window can be found via [2]this pull .

Listen, there is no courage or any extra courage that I know of to find out
the right thing to do. Now, it is not only necessary to do the right thing,
but to do it in the right way and the only problem you have is what is the
right thing to do and what is the right way to do it. That is the problem.
But this economy of ours is not so simple that it obeys to the opinion of
bias or the pronouncements of any particular individual, even to the President.
This is an economy that is made up of 173 million people, and it reflects
their desires, they're ready to buy, they're ready to spend, it is a thing
that is too complex and too big to be affected adversely or advantageously
just by a few words or any particular -- say, a little this and that, or even
a panacea so alleged.
-- D. D. Eisenhower, in response to: "Has the government
been lacking in courage and boldness in facing up to
the recession?"
