Major modea are channel-wide, and not a per-rank (or dimm or bank) mode.; We group these two modes together so that we can use four counters to track each of the major modes at one time. These major modes are used whenever there is an ISOCH txn in the memory controller. In these mode, only ISOCH transactions are processed.", 246 "PublicDescription": "Counts the total number of cycles spent in a major mode (selected by a filter) on the given channel. Major modea are channel-wide, and not a per-rank (or dimm or bank) mode.; This major mode is used to drain starved underfill reads. Regular reads and writes are blocked and only underfill reads will be processed.", 256 "PublicDescription": "Counts the total number of cycles spent in a major mode (selected by a filter) on the given channel. Major modea are channel-wide, and not a per-rank (or dimm or bank) mode.; Read Major Mode is the default mode for the iMC, as reads are generally more critical to forward progress than writes.", 266 "PublicDescription": "Counts the total number of cycles spent in a major mode (selected by a filter) on the given channel. Major modea are channel-wide, and not a per-rank (or dimm or bank) mode.; This mode is triggered when the WPQ hits high occupancy and causes writes to be higher priority than reads.
