Subject: [PATCH v5 0/6] xen/arm: vgic: Support 32-bit access for 64-bit register
Date: Mon, 9 Nov 2015 15:49:35 +0000	[thread overview]
Message-ID: <1447084181-13677-1-git-send-email-julien.grall@citrix.com> (raw)

Hi all,

This series aims to fix the 32-bit access on 64-bit registers. Some guest
OS such as FreeBSD and Linux (ITS and recently 32-bit guest using GICv3)
use 32-bit access and will crash at boot time.

For all the changes see in each patch.

Sincerely yours,

Julien Grall (6):
  xen/arm: vgic-v2: Implement correctly ITARGETSR0 - ITARGETSR7
    read-only
  xen/arm: vgic-v2: Handle correctly byte write in ITARGETSR
  xen/arm: vgic-v2: Don't ignore a write in ITARGETSR if one field is 0
  xen/arm: vgic: Optimize the way to store the target vCPU in the rank
  xen/arm: vgic: Introduce helpers to extract/update/clear/set vGIC
    register ...
  xen/arm: vgic-v3: Support 32-bit access for 64-bit registers
