[gem5-dev] Change in gem5/gem5[master]: sim-se: support lazy physical page allocs
Brandon Potter has uploaded a new patch set (#8). ( https://gem5-review.googlesource.com/c/public/gem5/+/12307 ) Change subject: sim-se: support lazy physical page allocs .. sim-se: support lazy physical page allocs This patch introduces Virtual Memory Areas (VMAs) to the Process class. Instead of binding virtual pages to physical pages during mmap/remap, we instead create a VMA that covers the region. Physical pages are allocated only if the virtual page is actually touched by the program. The binding occurs in fixupStackFault, renamed to fixupFault. Delaying the binding allows SE mode to support sparse usages of mmap.
