The SBI v2.0 specification is now frozen. The SBI v2.0 specification defines SBI debug console (DBCN) extension which replaces the legacy SBI v0.1 functions sbi_console_putchar() and sbi_console_getchar(). (Refer v2.0-rc5 at https://github.com/riscv-non-isa/riscv-sbi-doc/releases) This series adds support for SBI debug console (DBCN) extension in Linux RISC-V. [...]Here is the summary with links: - [v5,1/5] RISC-V: Add stubs for sbi_console_putchar/getchar() https://git.kernel.org/riscv/c/f503b167b660 - [v5,2/5] RISC-V: Add SBI debug console helper routines https://git.kernel.org/riscv/c/f43fabf444ca - [v5,3/5] tty/serial: Add RISC-V SBI debug console based earlycon https://git.kernel.org/riscv/c/c77bf3607a0f - [v5,4/5] tty: Add SBI debug console support to HVC SBI driver https://git.kernel.org/riscv/c/88ead68e764c - [v5,5/5] RISC-V: Enable SBI based earlycon support https://git.kernel.org/riscv/c/50942ad6ddb5 You are awesome, thank you!
Nathan points out that this has some semantic conflicts with a patch in Greg's TTY tree: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git/commit/?id=f32fcbedbe9290565e4eac3fd7c4c451d5478787 So I think the best bet is to wait on Greg's patch to land in Linus' tree, and then base a v6 of this patch set on that merged patch. I'm going to drop this one from for-next.
