[Xen-users] [Xen-Users] Issues Booting Dom0 on ARM Cortex A15

[Brandon Perez <a0225893@xxxxxx>]

Hello All,

   I'm experiencing some issues with booting into a Dom0 Linux Kernel 
on a embedded ARM Cortex A15 processor. Tracing through the code has 
shown me that the code is stuck in the idle_loop() function
(xen/arch/arm/domain.c:41). The function responds to only soft IRQs, and 
there are no scheduled tasklets to run.
   A little about my setup to start. I'm using uBoot to boot Xen, which 
is running a Linux 3.14 kernel. I'm currently on Xen's master branch,
where the Xen version is 4.6-unstable. The commit I'm operating at has 
the id ecdae1cfaa7f6123decaa1b9d7205c3ff726b941.
   After looking through the Xen code, I was unable to find a place 
where it explicitly jumps into the Dom0 kernel, which was what I was 
expecting to see. Is there somewhere in the source code where this is 
the case that I just missed? Or, is the initial jump into the kernel 
scheduled as a tasklet? If the latter is the case, then the kernel is 
never scheduled as a tasklet in the source code.
   Any tips on getting out the idle_loop() would be appreciated. Thanks 
in advance for your assistance.
Regards,

    Brandon Perez
