This patch contains several fixes to enable vPMU under TCG mode. It
4
first removes the checking of kvm_enabled() while unsetting
5
ARM_FEATURE_PMU. With it, the .pmu option can be used to turn on/off vPMU
6
under TCG mode. Secondly the PMU node of DT table is now created under TCG.
7
The last fix is to disable the masking of PMUver field of ID_AA64DFR0_EL1.

QEMU emulated hardware is always dma coherent with its guest. We do
4
annotate that correctly on the PCI host controller, but left out
5
virtio-mmio.
6
7
Recent kernels have started to interpret that flag rather than take
8
dma coherency as granted with virtio-mmio. While that is considered
9
a kernel bug, as it breaks previously working systems, it showed that
10
our dt description is incomplete.
11
12
This patch adds the respective marker that allows guest OSs to evaluate
13
that our virtio-mmio devices are indeed cache coherent.
