[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH for-next 0/6] Minimal build for RISCV
Hi all, This series introduces a minimal build for RISCV. It is based on Bobby's previous work from last year[0]. I have worked to rebase onto current Xen, as well as update the various header files borrowed from Linux. This series provides the patches necessary to get a minimal build working. The build is "minimal" in the sense that 1) it uses a minimal config and 2) files, functions, and variables are included if and only if they are required for a successful build based on the config. It doesn't run at all, as the functions just have stub implementations. My hope is that this can serve as a useful example for future ports as well as inform the community of exactly what is imposed by common code onto new architectures. The first 4 patches are mods to non-RISCV bits that enable building a config with: !CONFIG_HAS_NS16550 !CONFIG_HAS_PASSTHROUGH NR_CPUS == 1 !CONFIG_GRANT_TABLE respectively. The fifth patch adds the RISCV files, and the last patch adds a docker container for doing the build. To build from the docker container (after creating it locally), you can run the following: $ make XEN_TARGET_ARCH=riscv64 SUBSYSTEMS=xen The sources taken from Linux are documented in arch/riscv/README.sources. There were also some files copied from arm: asm-arm/softirq.h asm-arm/random.h asm-arm/nospec.h asm-arm/numa.h asm-arm/p2m.h asm-arm/delay.h asm-arm/debugger.h asm-arm/desc.h asm-arm/guest_access.h asm-arm/hardirq.h lib/find_next_bit.c I imagine some of these will want some consolidation, but I put them under the respective RISCV directories for now.
