All callers only care about boolean outcome. For this there's no point
in allocating a duplicate of the respective DRHD structure; a simple
boolean suffices (which eventually may want to become a count, such that
the "any ATS devices assigned state" can also clear again). With that
boolean, remove
When the flag is set, permit Dom0 to control the device (no worse than
what we had before and in line with other "best effort" behavior we use
when it comes to Dom0), but suppress passing through to DomU-s unless
ATS can actually be enabled for such devices (and was explicitly enabled
on the comman
Make the variable a tristate, with (as done elsewhere) a negative value
meaning "default". Since all use sites need looking at, also rename it
to match our usual "opt_*" pattern. While touching it, also move it to
.data.ro_after_init.
The only place it retains boolean nature is pci_ats_device(), f
The same set of conditions is used in three places, requiring to be kept
in sync. Introduce a helper to centralize these checks.
To allow all parameters of the new helper be pointer-to-const,
iommu_has_cap() also needs its 1st parameter to be constified. Beyond
that further "modernize" that functi
This is a prereq to us, in particular, respecting the "ATC required"
flag.
Note that ACPI_SATC_ATC_REQUIRED has its #define put in dmar.h, as we
try to keep actbl*.h in sync what Linux (who in turn inherit from ACPI
CA) has.

It's acpi_parse_one_rmrr() where the allocation is coming from (by way
of invoking acpi_parse_dev_scope()), or in add_one_user_rmrr()'s case
allocation is even open-coded there, so freeing would better also happen
there. Care needs to be taken to preserve acpi_parse_one_rmrr()'s

On a Sapphire Rapids system I noticed a line in the serial log
indicating a DMAR entry type we're not recognizing. While arranging
for it to be both recognized and respected, I noticed some further
potential for cleaning up.

When doing a rebuild with an xen/include/config/auto.conf already present in
the tree, failures from Kconfig are ignored since the target is present:

I didn't suggest adding anything right here; there may want/need to be new
