Subject: [PATCH v4 0/5] RISC-V: Add kexec/kdump support
Date: Mon, 19 Apr 2021 03:55:34 +0300 [thread overview]
Message-ID: <20210419005539.22729-1-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 (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
