[PATCH v3 0/9] RISC-V SBI debug console extension support
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 KVM RISC-V and Linux RISC-V. To try these patches with KVM RISC-V, use KVMTOOL from riscv_sbi_dbcn_v1 branch at: https://github.com/avpatel/kvmtool.git These patches can also be found in the riscv_sbi_dbcn_v3 branch at: https://github.com/avpatel/linux.git Changes since v2: - Rebased on Linux-6.6-rc5 - Handled page-crossing in PATCH7 of v2 series - Addressed Drew's comment in PATCH3 of v2 series - Added new PATCH5 to make get-reg-list test aware of SBI DBCN extension Changes since v1: - Remove use of #ifdef from PATCH4 and PATCH5 of the v1 series - Improved commit description of PATCH3 in v1 series - Introduced new PATCH3 in this series to allow some SBI extensions (such as SBI DBCN) do to disabled by default so that older KVM user space work fine and newer KVM user space have to explicitly opt-in for emulating SBI DBCN. - Introduced new PATCH5 in this series which adds inline version of sbi_console_getchar() and sbi_console_putchar() for the case where CONFIG_RISCV_SBI_V01 is disabled.
