PMSDSFR_EL1

Sampling Data Source Filter Register

Controls sample filtering by Data Source.

Configuration

This register is present only when FEAT_SPE_FDS is implemented. Otherwise, direct accesses to PMSDSFR_EL1 are UNDEFINED.

Attributes

PMSDSFR_EL1 is a 64-bit register.

S<m>, bit [m], for m = 63 to 0:

S[<m>] is the Data Source filter for IMPLEMENTATION DEFINED Data Source <m>.

S<m>Meaning
0b0

If PMSFCR_EL1.FDS is 1, do not record load operations that have bits [5:0] of the Data Source packet set to <m>.

0b1

Load operations with Data Source <m> are unaffected by PMSFCR_EL1.FDS.

The reset behavior of this field is:

When filtering on Data Source <m> is not supported, access to this field is RAZ/WI.

Access Instructions

Accesses to this register use the following encodings in the System register encoding space:
