Subject: [PATCH v1 0/8] xen/arm: vgic: Support 32-bit access for 64-bit register
Date: Fri, 25 Sep 2015 15:51:30 +0100 [thread overview]
Message-ID: <1443192698-16163-1-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 (only in the ITS) use 32-bit access and will
crash at boot time.
I took the opportunity to go further and optimize the way Xen is storing
registers such as GICD_IPRIORITYR, GICD_ITARGETR and GICD_IROUTER.
Major changes in v2:
- Use the helpers in GICv2
- Optimize the assembly input for vgic_regN_* helpers on arm32
- Add support for sign-extension generically
- Store GICD_{IPRIORITYR, ITARGETSR, IROUTER} in a better way
For all the changes see in each patch.
A branch has been pushed based on the lastest staging:
git://xenbits.xen.org/people/julieng/xen-unstable.git branch gicv3-32bit-v1
Sincerely yours,
Julien Grall (8):
xen/arm: io: remove mmio_check_t typedef
xen/arm: io: Extend write/read handler to pass the register in
parameter
xen/arm: Support sign-extension for every read access
xen/arm: vgic: ctlr stores a 32-bit hardware register so use uint32_t
xen/arm: vgic: Optimize the way to store GICD_IPRIORITYR in the rank
xen/arm: vgic: Optimize the way to store the target vCPU in the rank
xen/arm: vgic: Introduce helpers to read/write/clear/set vGIC register
...
xen/arm: vgic-v3: Support 32-bit access for 64-bit registers
