Date: Mon, 19 Apr 2021 03:55:34 +0300 From: Nick Kossifidis <mick@....forth.gr> To: linux-riscv@...ts.infradead.org, palmer@...belt.com Cc: paul.walmsley@...ive.com, linux-kernel@...r.kernel.org, Nick Kossifidis <mick@....forth.gr> Subject: [PATCH v4 0/5] RISC-V: Add kexec/kdump support This patch series adds kexec/kdump and crash kernel support on RISC-V. For testing the patches a patched version of kexec-tools is needed (still a work in progress) which can be found at: https://riscv.ics.forth.gr/kexec-tools-patched.tar.xz v4: * Rebase on top of "fixes" branch * Resolve Alex's comments v3: * Rebase on newer kernel tree * Minor cleanups * Split UAPI changes to a separate patch * Improve / cleanup init_resources * Resolve Palmer's comments v2: * Rebase on newer kernel tree * Minor cleanups * Properly populate the ioresources tre, so that it can be used later on for implementing strict /dev/mem * Use linux,usable-memory on /memory instead of a new binding * USe a reserved-memory node for ELF core header Nick Kossifidis (5): RISC-V: Add EM_RISCV to kexec UAPI header RISC-V: Add kexec support RISC-V: Improve init_resources RISC-V: Add kdump support RISC-V: Add crash kernel support arch/riscv/Kconfig | 25 ++++ arch/riscv/include/asm/elf.h | 6 + arch/riscv/include/asm/kexec.h | 56 +++++++ arch/riscv/kernel/Makefile | 6 + arch/riscv/kernel/crash_dump.c | 46 ++++++ arch/riscv/kernel/crash_save_regs.S | 56 +++++++ arch/riscv/kernel/kexec_relocate.S | 223 ++++++++++++++++++++++++++++ arch/riscv/kernel/machine_kexec.c | 193 ++++++++++++++++++++++++ arch/riscv/kernel/setup.c | 114 ++++++++------ arch/riscv/mm/init.c | 104 +++++++++++++ include/uapi/linux/kexec.h | 1 + 11 files changed, 784 insertions(+), 46 deletions(-) create mode 100644 arch/riscv/include/asm/kexec.h create mode 100644 arch/riscv/kernel/crash_dump.c create mode 100644 arch/riscv/kernel/crash_save_regs.S create mode 100644 arch/riscv/kernel/kexec_relocate.S create mode 100644 arch/riscv/kernel/machine_kexec.c -- 2.26.2
