Subject: [PATCH 0/3] RISC-V: Add kexec/kdump support
Date: Fri, 24 Apr 2020 20:12:11 +0300	[thread overview]
Message-ID: <20200424171214.1515457-1-mick@ics.forth.gr> (raw)

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. The patch is still
a work in progress but a draft version can be found at:

http://riscv.ics.forth.gr/kexec-tools.patch
