Attach_flags

enum L4Re::Rm::F::Attach_flags : l4_uint32_t

Flags for attach operation.

Enumerator
Search_addr	Search for a suitable address range.
In_area	Search only in area, or map into area.
Eager_map	Eagerly map the attached data space in.
No_eager_map	Prevent eager mapping of the attached data space.
Attach_mask	Mask of all attach flags.

Region_flags

enum L4Re::Rm::F::Region_flags : l4_uint16_t

Region flags (permissions, cacheability, special).

Enumerator
Rights_mask	Region rights.
R	Readable region.
W	Writable region.
X	Executable region.
RW	Readable and writable region.
RX	Readable and executable region.
RWX	Readable, writable and executable region.
Kernel	Kernel-provided memory (KUMEM).
Detach_free	Free the portion of the data space after detach.
Pager	Region has a pager.
Reserved	Region is reserved (blocked).
Caching_mask	Mask of all Rm cache bits.
Cache_normal	Cache bits for normal cacheable memory. This is the default if no other cache-related flag was specified.
Cache_buffered	Cache bits for buffered (write combining) memory.
Cache_uncached	Cache bits for uncached memory.
Ds_map_mask	Mask for all bits for cache options and rights.
Region_flags_mask	Mask of all region flags.
