Currently, unless a (non-default) ioreq server is explicitly disabled before
being destroyed, its gmfns will not be placed back into the p2m but still
released back into the ioreq_gmfn mask. This is somewhat counter-intuitive
and easily remedied by this small patch.
Signed-off-by: Paul Durrant
hvm_free_ioreq_gmfn has the sense of the ioreq_gmfn mask inverted; it
needs to set a bit to release the gmfn, not clear it.

Some parameters can only (validly) be set once. Some cannot be set

the XSM check, in a new hvm_allow_set_param() function for clarity.
Also, introduce hvm_allow_get_param() for similar reasons.

The level of switch nesting in those ops is getting unreadable. Giving

A guest has no need to touch these parameters and reading

The following 3 patches re-structure the code implementing HVMOP_set_param
and HVMOP_get_param.
Patch #1 gives each operation its own function
Patch #2 splits out checks for getting/setting non-reflexive params and
setting params with change-once semantics, as well as the XSM check into
separate
.

This patch re-works the dpci portio intercepts so that they can be unified
with standard portio handling thereby removing a substantial amount of
code duplication.

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 17 patches (which are also available in
all mmio and portio handled within Xen now goes through
process_io_intercept().

The state of in-flight I/O and how its completion will be handled are
logically separate and conflating the two makes the code unnecessarily
confusing.

The implementation of mmio and portio intercepts is unnecessarily different.
This leads to much code duplication. This patch unifies much of the
intercept handling, leaving only distinct handlers for stdvga mmio and dpci
portio. Subsequent patches will unify those handlers.
Signed-off-by: Paul
By removing the HVMIO_dispatched state and making all pending emulations
(i.e. all those not handled by the hypervisor) use HVMIO_awating_completion,
various code-paths can be simplified.
