Arm Generic Diagnostic Dump and Reset device enables a maintainer to request OS to perform a diagnostic dump and reset a system via SDEI event or an interrupt. This patchset adds support for the SDEI path. I do have a patch to enable the interrupt path as well but I'm holding it back since AGDI table is missing interrupt configuration fields (trigger type etc.). The recently published specification is available at https://developer.arm.com/documentation/den0093/latest The patchset was tested on Ampere Altra/Mt. Jade. The patchset applies on top of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm master git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git for-next/core What's the process with new ACPI tables? Should I submit a patch to ACPICA at first or is this fine?
