| I built an etch s390 kernel with some options that I find useful; CIFS support is chief among them, with DIAG support close behind (I also re-added tape support, because I find it useful). It's really intended for use in a VM environment, and if anyone wants it, add the following to sources.list: The signing key is F8B151AC and the key is available from pgp.mit.edu. The usual set of packages created with make-kpkg are up on that repository. There are no source changes from vanilla Etch, just compilation options. I haven't done a real patch to the sysconfig tools, but I added the following to /etc/sysconfig/hwup-dasd if test "$USE_DIAG" -eq "1" ; then echo 1 > $SYSFS$DEVPATH/use_diag fi (just before the online) And then, of course, /etc/sysconfig/hardware/ccw-0.0.0151 (my DASD VDISK) now contains USE_DIAG=1 This *should* speed performance of swap-on-VDISK, but I confess that I have not actually benchmarked it at all. (I've also done a patch to hwup-ccw to not reject tape out of hand, but since in my environment I typically pass the tape device around between guests rather than having it available at boot I haven't tested it yet. 3480/90 support works fine with my emulated 3490, in that I can read and write tar files to the /dev/ntibm0 device) Adam |
