Date: Tue, 16 Dec 2003 11:53:13 -0500 [thread overview]
Message-ID: <200312161653.hBGGrDkS002312@ccure.user-mode-linux.org> (raw)
This is another sizable set of changes. The major items in it are
Sapan's real-time clock patch - this allows UML to sleep accurately,
assuming enough idle cycles on the host
highmem support is back - it seems to work, but I haven't banged on
it to much. One caveat is that using highmem in skas mode is very slow because
of the need to do kmapping in the copy_user routines.
the start of SMP support in skas mode - it's not totally there, but
it now compiles and runs with one processor
it will now use /dev/anon if it's present on the host, which it won't
be until I release that patch, which will be fairly soon. In conjunction with
ubd-mmap, I'm seeing ~25% host memory use reduction.
There are also a number of smaller fixes, code cleanup, improved error
messages, etc.
Jeff
