I'd prefer to implement that enhancement on top of this
series (and may be on top of follow up PCI conversion)
if we have to do it (as the enhancement would be a bit
of off-topic churn, i.e. solving another issue that we
already have).

Promoting the ISADeviceClass::build_aml idea to a more general approach
certainly makes sense.  ISA update is fine.  Skimmed the other updates
too, looks all sane to me.

I like this. Have one further enhancement idea before
applying this, sent on list.

[PATCH 00/35] pc/q35: refactor ISA and SMBUS AML generation

2022-05-16 Thread Igor Mammedov


Series is excerpt form larger refactoring that does
the same for PCI devices, but it's too large at this
point, so I've split off a relatively self-contained
ISA/SMBUS patches into a smaller separate series, and
PCI refactoring will follow up on top of this series
using the same AcpiDevAmlIf interface.

Series consolidates and unifies how pc/q35 machine
generates AML for ISA and SMBUS devices. It adds
a new more generic interface 'AcpiDevAmlIf' that
replaces ISA specific ISADeviceClass::build_aml
hook and should allow to use the same approach
(i.e. ask a device to provide its own AML) but
not limited to ISA bus.
Series applies AcpiDevAmlIf interface to a few
ISA devices that were already using
ISADeviceClass::build_aml and to devices /tpm,
applesmc,pvpanic,ipmi/ that were generated in
custom way. The AML generation for the later
class is normalized to behave like any other
ISA device that were using ISADeviceClass::build_aml
and converted to interface 'AcpiDevAmlIf'.
It simplifies process of building DSDT and
eliminates custom probing/wiring for those devices
as AML for them is generated at the time ISA/SMBUS
is enumerated.

Changes to DSDT tables QEMU generates are mostly
contextual where devices scattered across DSDT
are consolidated under respective device that
hosts bus they are attached to.

PS:
 + series adds several ACPI tests for devices
   that were missing them.
