Subject: [Qemu-devel] How can I exercise the CPU reset code for iMX boards?
Date: Thu, 09 Feb 2017 11:29:49 +0000	[thread overview]
Message-ID: <8760kjy53m.fsf@linaro.org> (raw)


Hi Jean-Christophe,

As part of the MTTCG work I've been tweaking the reset handling code in
imx6_src.c to handle the fact the reset is now asynchronous:

  https://github.com/stsquad/qemu/commit/ef8e78e7adccb8c881a1772ac01cd78c6b436de3

The only image I currently have is from Peter's image zoo which is a
simple kernel and initrd. I can successfully offline/online CPUs but
with printfs I can see this never causes them to be reset. So a couple
of questions:

  - does Linux even exercise the reset bit?
  - if not are there any test OS images that do?

and a follow-up bonus questions:

  - what's the QEMU invocation for the iMX boards with a SD card?
  - are there any full images you suggest with a more complete rootfs?

Regards,

--
