my two cents,

The riscv build failed on Linux -next 20210426 tag kernel due to below warnings / errors. Following builds failed.

• riscv (tinyconfig) with gcc-8
• riscv (allnoconfig) with gcc-8
• riscv (tinyconfig) with gcc-9
• riscv (allnoconfig) with gcc-9
• riscv (tinyconfig) with gcc-10
• riscv (allnoconfig) with gcc-10

steps to reproduce:

# TuxMake is a command line tool and Python library that provides # portable and repeatable Linux kernel builds across a variety of # architectures, toolchains, kernel configurations, and make targets. # # TuxMake supports the concept of runtimes. # See https://docs.tuxmake.org/runtimes/, for that to work it requires # that you install podman or docker on your system. # # To install tuxmake on your system globally: # sudo pip3 install -U tuxmake # # See https://docs.tuxmake.org/ for complete documentation.

tuxmake --runtime podman --target-arch riscv --toolchain gcc-8 --kconfig allnoconfig

Thank you Naresh for the report, I will fix that today.

Thanks again,

Alex
