Would it be possible for the vmcp kernel driver to have an option to
pre-allocate some fixed size of contiguous memory and hold onto it? This would
prevent fragmentation which can hit you at any time. I remember using vmcp from
a Linux based installer which typically started by downloading large

Well...
Perhaps pawing through /etc/profile _might_ be edifying.
You can cheat by:
cd /etc
find . -type f -print | while read F ; do grep TERM "${F}" && echo "${F}" ;
done
to find out where this can be getting set. It might even be somewhere
under /etc/defaults but don't quote me on that.

Hi,
I'm trying to figure out why TERM is being set to linux instead of dumb on the
GRUB_CMDLINE_LINUX_DEFAULT in the /etc/default/grub line of a system-z guest on
install of SLES 12 SP2. TERM=dumb is set in the parmfile but after the
install it's set to linux. Does anyone know of a way to g
An enhancement to DIAG 8 to use a buffer list like DIAG 250 does for disk
I/O would circumvent the contiguous memory requirement. The Ry register
already contains a flag byte that could be extended to indicate Rx+1 being
a buffer list rather than the buffer.

Yes, this is memory fragmentation.
Heiko recently did some changes that should improve the situation.

Fragmentation. Vmcp needs contiguous real storage. So if there is not a
slab of 1MB in size hanging around then it will complain.

Hello list,
We use vmcp extensively to issue CP commands. More and more I'm seeing
this error:
Error: Could not issue CP command: Cannot allocate memory
I always use the --buffer=1M flag to be able to get the largest output. I've
bumped up the VM size from 2 to 3 to 4GB, but still see it. We ha
