Hi,
I decided to try out the recently merged EIP-93 module on my MediaTek
MT7621. Ran into this kernel crash "Unable to handle kernel paging
request", full trace is included below.
I'm happy to dig into this a little, but have no idea what I'm doing in
kernel land so I thought I would post first in case it was super obvious to
skilled eyes.
I enabled the hardware by adding the following block to mt7621.dtsi:
crypto: crypto@1e004000 {
status = "okay";
compatible = "airoha,en7581-eip93",
"inside-secure,safexcel-eip93ies";
reg = <0x1e004000 0x1000>;
interrupt-parent = <&gic>;
interrupts = <GIC_SHARED 19 IRQ_TYPE_LEVEL_HIGH>;
};
Basic testing seemed to show it was working. I ran `cryptsetup benchmark`
without issue and it showed the desired speed increases.
Mounting an encrypted disk caused the displayed crash, this is repeatable.
The drive had been previously set up and encrypted before enabling the
module.
Attempting to rmmod the module also caused a crash, I have included its
trace too.
Thanks for your time,
David
(Sorry for the confusion, first email got bounced for including html format)
