Re: [Xen-devel] [PATCH 0/5] Fix multiple issues with the interrupts on ARM

[Andrii Anisov <andrii.anisov@xxxxxxxxxxxxxxx>]

Hello,

I wonder if this patchset going to be revised and applied?

It appeared pretty useful for us.

We are experimenting with an Android as an only DomU. For sure it was done with giving to Android direct access to iomem and delivering some hw irq's to DomU.

Eventually we had showstopper issue with hw irqs delivery to DomU kernel. At some moment some IRQs was not delivered to DomU. The issue disappeared with applying this patchset. 

Sincerely,

Andrii Anisov.

Hello,

This patch series aims to fix different issues on Xen on ARM with the
arndale and the versatile express:
  - Handle correctly one shot IRQ (fixed by patch 3)
  - Make timers work with heavy load (fixed by patch 2)
  - Make ethernet card works on the TC2 (fixed by patch 5)

Some of these patches (2 and 5) are proof of concept. I would be happy if
someone find a better solution :).

Cheers,

Julien Grall (4):
  xen/arm: Physical IRQ is not always equal to virtual IRQ
  xen/arm: Don't reinject the IRQ if it's already in LRs
  xen/arm: Rename gic_irq_{startup,shutdown} to gic_irq_{mask,unmask}
  xen/arm: Only enable physical IRQs when the guest asks
