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);
