The DSDT ACPI table used for Neoverse reference design platforms include the _LPI control method for the kernel to enter idle states. This patch series fixes bugs in the existing _LPI control method due to which certain high level OS failed to boot on the supported Neoverse reference design platforms. For each platform, the fixes include - clearing level ID value as the platform supports only platform co-ordinated _LPI and removing residency counter frequency as the platform does not implement residency counter. In addition to this, the RD-N2 and RD-N2-Cfg1 platforms are direct connect platforms and so the _LPI control method for cluster is removed.
