Subject: [PATCH v4 0/5] xen/arm: vgic: Support 32-bit access for 64-bit register
Date: Mon, 12 Oct 2015 15:22:35 +0100 [thread overview]
Message-ID: <1444659760-24123-1-git-send-email-julien.grall@citrix.com> (raw)
Hi all,
This series aims to fix the 32-bit access on 64-bit register. 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.
Major changes in v4:
- Patch #1-#6 of the previous version has been applied
- Split "Optimize the way to store the target vCPU in the rank" in 3
patchs to avoiding fixing a bug (byte access), changing behavior
(handle zero write), and the actual optimizing in a single patch.
Sincerely yours,
Julien Grall (5):
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
