[PATCH 0/4] arm64: dts: renesas: r8a779f0: CPU topology improvements

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



	Hi all,

Currently, the R-Car S4-8 DTS describes a single Cortex-A55 CPU core
only.  This patch series completes the description of the Cortex-A55
lusters by describing L3 caches, CPU cores 1-7, CPU map, PSCI for CPU bring up,
CPUIdle, and CPU core clocks.

This has been tested on the Spider development board, where now all 8
Cortex-A55 CPU cores are available after boot.  All but the first CPU
core can be controlled from sysfs (/sys/*/*/cpu/cpu[0-7]/online).
CPU core performance follows the CPU core clocks, when changing the
frequency of the latter.

I plan to queue this in renesas-devel for v5.20.

Thanks for your comments!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
