AMCIDR2

This is a collection of Intel®’ IA32® Software Developer's Manuals (URL of the day) and AMD' AMD64 Architecture Programmer's Manual together with the related specifications, application notes, white papers, and change logs. The collection aims to keep all available revisions. It was originally created by Michal Necasek, see OS/2 Museum.

If you have a public document, related to the IA32® specifications and missing from the collection, please mail it to me. The content of this URL and all sub-ULRs is available for convenient bulk download by rsync x86docs password "" (empty).

AMCIDR2, Activity Monitors Component Identification Register 2

Purpose

Configuration

It is IMPLEMENTATION DEFINED whether AMCIDR2 is implemented in the Core power domain or in the Debug power domain.

This register is present only when FEAT_AMUv1 is implemented, an implementation implements AMCIDR2, and FEAT_AMU_EXT is implemented. Otherwise, direct accesses to AMCIDR2 are RES0.

Preamble.

Reads as 0x05.

Access to this field is RO.

Accessing AMCIDR2

Accesses to this register use the following encodings:

Accessible at offset 0xFF8 from AMU

When ImpDefBool("AMU CoreSight management registers ignore access controls"), accesses to this register are RO.
When FEAT_RME is implemented, FEAT_AMU_EXTACR is implemented, an access is Secure, and AMROOTCR().RA IN {'001', '000'}, accesses to this register are RAZ/WI.
When FEAT_RME is implemented, FEAT_AMU_EXTACR is implemented, an access is Realm, and AMROOTCR().RA IN {'010', '000'}, accesses to this register are RAZ/WI.
When FEAT_RME is implemented, FEAT_AMU_EXTACR is implemented, an access is Non-secure, and AMROOTCR().RA != '011', accesses to this register are RAZ/WI.
When FEAT_RME is not implemented, FEAT_AMU_EXTACR is implemented, an access is Non-secure, and AMSCR().NSRA == '0', accesses to this register are RAZ/WI.
Otherwise, accesses to this register are RO.
