[PATCH 8/8] platform/x86/amd: pmc: update metrics table info for Pink Sardine

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Starting from Pink Sardine, number of IP blocks were added to the
SoC and the PMFW has the ability to give debug stats on each the IP blocks
after a S0ix cycle within part of the SMU metrics table. Add this new
capability to the driver.
