Memory management

Functions allow managing process address spaces.

syscalls_memMap (syscalls_mmap)

GETFROMSTACK(ustack, void *, vaddr, 0);
GETFROMSTACK(ustack, size_t, size, 1);
GETFROMSTACK(ustack, int, prot, 2);
GETFROMSTACK(ustack, int, flags, 3);
GETFROMSTACK(ustack, oid_t *, oid, 4);
GETFROMSTACK(ustack, offs_t, offs, 5);

Maps part of object given by oid, offs and size at vaddr with protection attributes given by prot using mapping mode defined by flags.

syscalls_memUnmap (syscalls_munmap)

GETFROMSTACK(ustack, void *, vaddr, 0);
GETFROMSTACK(ustack, size_t, size, 1);

Unmaps part of address space defined by vaddr and size.

syscalls_memDump (syscalls_mmdump)

Returns memory map entries associated with calling process.

syscalls_memGetInfo (syscalls_meminfo)

GETFROMSTACK(ustack, meminfo_t *, info, 0);

syscalls_memGetPhysAddr (syscalls_va2pa)

GETFROMSTACK(ustack, void *, va, 0);
