this is the full output:

GT_PERF_STATUS: 0x00000700
RPSTAT1: 0x00048700
Render p-state ratio: 7
Render p-state VID: 0
Render p-state limit: 255
RPNSWREQ: 1050MHz
CAGF: 350MHz
RP CUR UP EI: 685us
RP CUR UP: 56us
RP PREV UP: 0us
RP CUR DOWN EI: 21816us
RP CUR DOWN: 57us
RP PREV DOWN: 0us
Lowest (RPN) frequency: 350MHz
Nominal (RP1) frequency: 350MHz
Max non-overclocked (RP0) frequency: 1050MHz
Max overclocked frequency: 1050MHz

seems like RPNSWREQ changes properly but CAGF doesn't
