Alternative physmap via memory:physical@<mem type>.
Allows doing what SYS_PHYSMAP
does but using SYS_FMAP
(allows setting PROT_WRITE, same as PHYSMAP_WRITE), and where PHYSMAP_NO_CACHE
and PHYSMAP_WRITE_COMBINE
are replaced by 3 separate "files", i.e. memory:physical@wb
/memory:physical
, memory:physical@uc
, and memory:physical@wc
.
