<div dir="ltr">Hi,<div><br></div><div>I want to understand the mechanism by which linux marks a page as referenced. </div><div><br></div><div>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. </div><div><br></div><div>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?</div><div><br></div><div>Thanks a lot. Please tell me if there are some manuals/other forums I could refer to for this question. </div><div><br></div><div>-- <br><div>Rakhi Hemani<div>Phd Scholar</div><div>Roll Number PhD1207</div></div>
