Priority: Medium, required for standard compliance (but makes the
code bigger)
o Dynamic Loader
^^^^^^^^^^^^^^
Description: At some point in the future, I intend to port the XFLAT
dynamic loader into NuttX (see http://xflat.sourceforge.net/).
That would allow NuttX to dynamically load and link
external code in a mounted filesystem.
Status: Open
Priority: Low, Nice feature and I might do it someday
o Memory Managment (mm/)
^^^^^^^^^^^^^^^^^^^^^^
@ -289,6 +278,17 @@ o File system / Generic drivers (fs/, drivers/)
Status: Open
Priority: Medium-Low
Description: At present, mmap() only works with file descriptors associated
with a ROMFS file system. Generalize this logic so that if
mmap is not supported by the file system or block driver, it
will allocate memory and copy the file into RAM. This would
need some centralized logic so that the memory region would
be shared on later mmap()'s on the same inode. Reference counting
would be required so that the multiply mmap()'ed region persists
until the last munmap().
