vbetool, mm kernels and mmap

vbetool, mm kernels and mmap

[Norbert Preining]

Hi all!

Playing around with suspend 2 ram I have to use vbetool.
Using kernel 2.6.14-rc4-mm1 (and probably earlier) I get:

program vbetool is using MAP_PRIVATE, PROT_WRITE mmap of VM_RESERVED
memory, which is deprecated. Please report this to linux-kernel@vger.kernel.org

Well, here I report. It is the debian package version 0.3 of vbetool.


Best wishes

Norbert

It's actually coming from lrmi rather than vbetool itself. lrmi seems to
use it to set up a set of memory to mimic the <1MB space, and again to
actually gain access to low memory. Is there documentation about this
deprecation anywhere?
