[Xen-devel] [PATCH 0/9] xen/arm: Bunch of fixes for the vGIC emulation

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hi all,

The main point of this series is to fix the access to any register when the
user doesn't write at the base offset of the registers.

At the same, I took the opportunity to re-arrange the emulation and dropping
any registers which doesn't exists or not required by the spec.

This series is based on "xen/arm: vgic: Support 32-bit access for 64-bit
register" [1]. I've provided a branch with the 2 series applied:

git://xenbits.xen.org/people/julieng/xen-unstable.git branch gic-emulation-v1

Sincerely yours,

  xen/arm: vgic-v3: Use the correct offset GICR_IGRPMODR0
  xen/arm: vgic-v3: Only emulate identification registers requested by
    the spec
  xen/arm: vgic: Properly emulate the full register
  xen/arm: vgic-v3: Remove GICR_MOVALLR and GICR_MOVLPIR
  xen/arm: vgic: Re-order the register emulations to match the memory
    map
  xen/arm: vgic-v3: Emulate read to GICD_ICACTIVER<n>
  xen/arm: vgic-v3: Remove spurious return in GICR_INVALLR
  xen/arm: vgic-v3: Don't implement write-only register read as zero
  xen/arm: vgic-v3: Make clear that GICD_*SPI_* registers are reserved
