I want to understand the mechanism by which linux marks a page as
According to the documentation in "Understanding The Linux Virtual Memory
Manager" Figure 11.6 and Table 3.1, there is a bit PG_referenced that can
be queried to test if the page was accessed.
I want to ask if the CPU can/does set that bit. Also, is this bit set on a
LLC miss or on a TLB access?
Thanks a lot. Please tell me if there are some manuals/other forums I could
refer to for this question.
