CAAM backlog support for 4.19 kernel?

jimbrooke-l3 — Fri, 04 Oct 2019 13:39:29 GMT

Hi,

I'm just starting to play with the LS1046ARDB devel board. Is there a currently working caam driver that has backlog support? The kernel included with the NXP SDK hangs as soon as you try to do IO to an encrypted disk due to lacking backlog support.

Thanks

CAAM driver does not have backlog support, but there is another disk
encryption solution. Please check this document. It is for i.MX product
family, but the idea is applicable for LS1046 as well.

Hope this helps,
Platon

I just have discovered that the document is in a restricted area, sorry for providing a non-working link,

I will contact you by e-Mail to discuss how the document can be provided to your company.
