hifn_7955 and Linux

[Andreas Gerlich]

Hello,

I have following hardware:

	net5501 - Board of Soekris with AMD GoedeLX Processor 500 MHz
	vpn1401 - PCI-Card with HIFN 7955 Crypto acceleration chip also
		  from Soekris.

I'am use Debian Lenny/sid on this board. It works fine.
I can also use the geode-aes engine for encryption partiions on the HD.
But I can only use 128 bit keysize with this engine.

So I bougth the vpn1401 card with the HIFN 7955 Chip. I tought that this
Chip is fully supported by the hifn_795x module which is included in the
kernel 2.6.27 of Lenny/sid.
But it doesn't work. I get errors when I try tu use the AES-engine
of the hifn_795x/Chip/Module.

Can you tell me what the parameters are nessesary for cryptsetup to use
the hifn_7955?

I try with cryptsetup: aes-cbc-essiv:sha256, keysize=256 but that
doesn't work.

Regards

Please show the dmesg output for the failed command and optionally (but
very helpful) enable debug and send us its output.
