Hello Pranav,
Would it be possible to extend this change to the Juno aswell as the
platform has a Null Residency Counter and doesn't support OS Initiated LPI ?
Another remark is that for RdV1MC, RdN2, RdV1 and RdN2Cfg1 platforms,
CPUs don't need to be encapsulated anymore in cluster objects
Cf:
Device (CL00) { // Cluster 0
Name (_HID, "ACPI0010")
Name (_UID, 0)
...
}
since Clusters don't have any additional information. But keeping them
is correct aswell.
Regards,
Pierre

Idle states for RD platforms

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.
