Then, the "entry" sounds like a physical (v.s. "logical") table entry, e.g. a PTE that we usually say?
I choose entry because it is related to PTE and in most cases you want to work on the entries. The replication of entry to item is somewhat hidden.
From a HW perspective the TLB should be loading entries.
In that case, "entry" should be a single "physical" element v.s. "logical", right? Because that's what HW/TLB physically loads.
I would say HW/TLB loads logical entries when it supports contiguity. It read a single table item and expand it to the larger TLB "entry".
