[Qemu-devel] [PATCH for-3.0 0/2] a couple of GICv2 bug fixes

Posted by Peter Maydell 7 years, 3 months ago

These patches fix bugs in our GICv2 implementation that we noticed
in the course of reviewing Luc's patchset to add virtualization
support to it.

Patch 1 is a missing bounds check, effectively. Luckily there
was a mask operation in place that means it's not actually
possible to do anything nasty as a result.

Patch 2 fixes GICD_ITARGETSR for non-11MPCore GICs, which is
necessary to run Jailhouse as a guest.
