Move all work to the host_pci_config_copy helper function,
which we can easily reuse when adding q35 support.
Open sysfs file only once for all values. Use pread.
Proper error handling. Fix bugs:

did because val was passed by value no

Hi,
We have some code in our tree to support pci passthrough of intel
graphics devices (igd) on xen, which requires some chipset tweaks
for (a) the host bridge and (b) the lpc/isa-bridge to meat the
expectations of the guest driver. For kvm we need pretty much
the same, also the requirements fo

In general, code running withing a realize() method should not exit() on
error. Instad, errors should be propagated through the realize()
method. Additionally, the realize() method should fail cleanly,
i.e. carefully undo its side effects such as wiring of interrupts,
mapping of memory, and so fo

buffer_find_nonzero_offset() is a hot function during live migration.
Now it use SSE2 intructions for optimization. For platform supports
AVX2 instructions, use the AVX2 instructions for optimization can help
to improve the performance about 30% comparing to SSE2.
