Hello all,
the subject line basically says it all. I was trying to offload IPsec
encryption to the hardware encryption engine on my Geode LX800. The exact
same setkey command works fine with software aes.
In case it matters: this is with a MSEP800/A board from DIGITAL-LOGIC AG
(see
http://www.digitallogic.com/english/products/catalog07/epic_detail.asp?id=MSEP800_L).
Did anybody ever succeed with Geode hardware accelerated IPsec? Did you
have to do anything special?
Please enable as much kernel debugging options as possible and rerun the
test - our mind readers are currently on vacations, so we fail to
find a problem.
If there will not be any signs of the problem, try to add several printk
into main geode crypto functions (there are not that many of them) or
press various sysrq combinations to determine where stall happens.
As additional debug patch: try this one:
diff --git a/drivers/crypto/geode-aes.c b/drivers/crypto/geode-aes.c
