Hello,
I am working on getting HW acceleration working via the talitos
driver for the 8347E.
We are running 2.6.25.4 with the realtime patchset and ubifs.
I have a testbed setup of machines like:
A<->B<->C<->D
I am running a talitos aware kernel on B and C. (I cloned linux-2.6 and
copied talitos.[c|h] and changed Kconfig and Makefile in drivers/crypto.
Unfortunately, I am still seeing only about 20 Mbit/sec from iperf (same
as before I installed the talitos module). I also don't see any talitos
stuff in the drivers:
# cat /proc/crypto | grep -i talitos
#
I do have a /sys/bus/of_platform/drivers/talitos folder with uevent,unbind,bind
though.
dmesg | grep -i talitos also returns nothing.
What is the best way to go about debugging the crypto stuff? Should I jump
in and start printk'ing everything or ? Do I need other changes from
the tree than the taliltos driver?
BTW, here is the relevent entry in the DTS:
crypto@30000 {
device_type = "crypto";
model = "SEC2";
compatible = "talitos";
reg = <30000 10000>;
interrupts = <b 8>;
interrupt-parent = < &ipic >;
num-channels = <4>;
channel-fifo-len = <18>;
exec-units-mask = <0000007e>;
descriptor-types-mask = <01010ebf>;
};
Thanks,
Barry
