Hi Ariel,
I'm sorry about the way I handled your patch. I should have spent more time
working with you to develop your patch.
I agree that the Reported-by tag doesn't properly reflect the contribution you
made, I should have realised that at the time.
cheers
(Apologies for the brief reply,
The global static should pre-define the type and the NOP free function can
be now left as NULL.

Continue converting drivers to the new interface. Introduce
ops->blocked_domain to hold the global static BLOCKED domain and convert
all drivers supporting BLOCKED to use it.
This makes it trivial for dart and iommufd to convert over to
domain_alloc_paging().
There are six drivers remaining:
This flag just caches if the IO page size is larger than the CPU
PAGE_SIZE. This only needs to be checked in two places so remove the
confusingly named cache.
dart would like to not support paging domains at all if the IO page size
is larger than the CPU page size. In this case we should ideally
Move the global static blocked domain to the ops and convert the unmanaged
domain to domain_alloc_paging.

In many cases the dev argument will now be !NULL so we should use it to
finalize the domain at allocation.
Make apple_dart_finalize_domain() accept the correct type.

Following the pattern of identity domains, just assign the BLOCKED domain
global statics to a value in ops. Update the core code to use the global
static directly.
Update powerpc to use the new scheme and remove its empty domain_alloc
callback.

Since the IDENTITY and BLOCKED behaviors were moved to global statics all
that remains is the paging domain. Rename to
apple_dart_attach_dev_paging() and remove the left over type check.

Testcase "Parsing of all PMU events from sysfs" parse events for
all PMUs, and not just cpu. In case of powerpc, the PowerVM
environment supports events from hv_24x7 and hv_gpci PMU which
is of example format like below:
- hv_24x7/CPM_ADJUNCT_INST,domain=?,core=?/
- hv_gpci/event,partition_id=?/

The CXL driver plans to use cper_print_aer() for logging restricted CXL

therefore not usable by the CXL drivers built as loadable modules. Export
