RE: [BUG] Xen build for RCAR failing

Hello Oleksandr Tyshchenko,

Thanks for your quick response. With Xen stable 4.13 branch, the mentioned issue is solved.


Is there any document which I could refer to bring up Xen[DOM0] and have an hands on ? because am currently seeing no output after this


(XEN) *** Serial input to DOM0 (type 'CTRL-a' three times to switch input)

(XEN) Freed 324kB init memory.

(XEN) *** Serial input to Xen (type 'CTRL-a' three times to switch input)


Attaching the complete logs for reference.


Mit freundlichen Grüßen / Best regards

Hello Bertrand,

I succeeded in building the core minimal image with dunfell and its compatible branches [except xen-troops (modified some files to complete the build)].

But I face the following error while booting.

(XEN) ****************************************
(XEN) Panic on CPU 0:
(XEN) Timer: Unable to retrieve IRQ 0 from the device tree
(XEN) ****************************************



The reason for that problem *might* be in the arch timer node in your device tree which contains "interrupts-extended" property instead of just "interrupts". As far as I remember Xen v4.12 doesn't have required support to handle "interrupts-extended".

It went in a bit later [1]. If this is the real reason, I think you should either switch to the new Xen version or modify your arch timer node in a way to use the "interrupts" property [2]. I would suggest using the new Xen version if possible (at least v4.13).
