This patch series re-works much of the code involved in emulation of port
and memory mapped I/O for HVM guests.
The code has become very convoluted and, at least by inspection, certain
emulations will apparently malfunction.
The series is broken down into 18 patches (which are also available in
The check is done at the wrong point (since it is irrelevant if the
I/O is to be handled by the hypervisor) and its functionality can be
covered by returning X86EMUL_UNHANDLEABLE from hvm_send_assist_req()
instead.
This patch also removes the domain_crash() call from
hvm_send_assist_req().
...in hvmemul_read/write()
Add hvmemul_phys_mmio_access() and hvmemul_linear_mmio_access() functions
to reduce code duplication.

The struct just contains three methods and no data, so the name
hvm_mmio_ops more accurately reflects its content. A subsequent patch
introduces a new structure which more accurately warrants the name
hvm_mmio_handler so doing the rename in this purely cosmetic patch avoids
conflating functional
When memory mapped I/O is range checked by internal handlers, the length
of the access should be taken into account.

The code in hvmemul_do_io() that tracks large reads or writes, to avoid
re-issue of component I/O, is defeated by accesses across a page boundary
because it uses physical address. The code is also only relevant to memory

This patch re-factors the code and moves it
By removing the calls in hvmemul_do_io() (which is replaced by a single

If memory mapped I/O is 'chunked' then the I/O must be re-emulated,
otherwise only the first chunk will be processed. This patch makes
sure all I/O from a buffer is re-emulated regardless of whether it
is a read or a write.
