Comment # 8
on bug 907692
from grant k
for 3 different 64-bit CPU cases, all running opensuse 13.2
(1) CASE: @ VM, with flags: +ssse3 +aes
(2) CASE: @ laptop, with flags: +ssse3 -aes
(3) CASE: @ desktop, with flags: -ssse3 -aes
there's different behavior based on available CPU flags, requiring manual
intervention for crypto module insertion; autodetection/insertion of
cpu-specific modules doesn't seem to work
(1) CASE: @ VM, with flags: +ssse3 +aes

echo "alias sha512 sha512_generic" >> /etc/modprobe.d/99-local.conf
modprobe aes
modprobe sha512
but, as there's no 'generic' module alternative for sha256/sha1, still
modprobe sha256
modprobe: ERROR: could not insert 'sha256_ssse3': No such device
modprobe sha1
modprobe: ERROR: could not insert 'sha1_ssse3': No such device
so,
lsmod | egrep "aes|sha|sse" | grep -v sharp
sha512_generic 12942 0
aes_x86_64 17131 0
two questions:
(A) why is this autodetection/insertion failing in the 1st place?
(B) for case (3), where are the 'generic' modules for sha256 & sha1? sha512 is
available ...
