movealloc

include/mem/movealloc.h View source View on GitHub

Implements movealloc.

this feature allows us to take a given virtual pointer, and copy its pages over to pages in the correct domain, and change the page tables to point to these correct pages. this is a form of “mini page migration” that we use to move over initial allocations to the right node. this lives entirely separate from our real page migration

Functions

movealloc_full

void movealloc_full(
    domain_id_t domain,
    void *ptr,
    struct vmm_request rq
)

source

this will always panic upon alloc failure - only to be used in init code!

movealloc_exec_all

void movealloc_exec_all(void)
