Change Details

Update pagesizes[] to include the ATTR_CONTIGUOUS L3C page size, which is 64KB when the base page size is 4KB and 2MB when the base page size is 16KB. Add support for L3C pages to shm_create_largepage(). Add support for creating L3C page mappings to pmap_enter(psind=1). Add support for reporting L3C page mappings to mincore(2) and procstat(8). Update vm_fault_soft_fast() and vm_fault_populate() to handle multiple superpage sizes. Declare arm64 as supporting two superpage reservation sizes, and simulate two superpage reservation sizes, updating the vm page's psind field. (The next patch will replace this simulation. This patch is already big enough.) Co-authored-by: Eliot Solomon <ehs3@rice.edu>
