Hi Sebastian,

Will these ports work on the RISC-V designs from SiFive (https://www.sifive.com)?

Hello Molock,

we work currently on the SMP support for RISC-V (32-bit and 64-bit). The aim is to run the tests on Qemu and a FPGA Board with two BOOMv2 processors.


My current task is a tool chain update to include a bug fix for:


This fix is necessary to run 64-bit applications in an address rage above 0x80000000 (SDRAM address in some standard chips). We need also specialized GCC multilibs for this.

I would like to merge the riscv32 and riscv64 tool chain into one riscv tool chain. There was some discussion necessary with the RISC-V maintainers to achieve this.

The overall work should be finished in two to three months.
