Public bug reported:
My StarFive VisionFive 2 v1.3B board has a SoC with 5 cores:
1 32 bit RISC-V core which is not used by Linux and not reported in
/proc/cpuinfo but only in the device-tree as cpu@0
riscv,isa = “rv64imac_zba_zbb”;
riscv,isa-extensions = “i”, “m”, “a”, “c”, “zba”, “zbb”, “zicntr”, “zicsr”,
“zifencei”, “zihpm”;
4 64 bit RISC-V cores which are sued by Linux and are reported in /proc/cpuinfo.
riscv,isa = “rv64imafdc_zba_zbb”;
riscv,isa-extensions = “i”, “m”, “a”, “f”, “d”, “c”, “zba”, “zbb”, “zicntr”,
“zicsr”, “zifencei”, “zihpm”;
As can be seen from the riscv,isa value all are 64bit.
The hardware information tab shows 7 CPUs with incorrect information
instead of the 4 cores provided by the system. The same is shown both in
the new and old web interface.
