2023-01-20include/hw/ppc: Supply a few missing includesMarkus Armbruster
A few headers neglect to include headers they need. They compile only if something else includes the required header(s) first. Fix that.

2022-04-20ppc/pnv: Remove PnvOCC::psi linkCédric Le Goater

2020-09-18qom: Remove module_obj_name parameter from OBJECT_DECLARE* macrosEduardo Habkost
One of the goals of having less boilerplate on QOM declarations is to avoid human error. Requiring an extra argument that is never used is an opportunity for mistakes. Remove the unused argument from OBJECT_DECLARE_TYPE and OBJECT_DECLARE_SIMPLE_TYPE. Coccinelle patch used to convert all users of the macros: @@ declarer name OBJECT_DECLARE_TYPE; identifier InstanceType, ClassType, lowercase, UPPERCASE; @@ OBJECT_DECLARE_TYPE(InstanceType, ClassType, - lowercase, UPPERCASE); @@ declarer name OBJECT_DECLARE_SIMPLE_TYPE; identifier InstanceType, lowercase, UPPERCASE; @@ OBJECT_DECLARE_SIMPLE_TYPE(InstanceType, - lowercase, UPPERCASE); Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Cédric Le Goater <clg@kaod.org> Acked-by: Cornelia Huck <cohuck@redhat.com> Acked-by: Igor Mammedov <imammedo@redhat.com> Acked-by: Paul Durrant <paul@xen.org> Acked-by: Thomas Huth <thuth@redhat.com> Message-Id: <20200916182519.415636-4-ehabkost@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

2020-09-09Move QOM typedefs and add missing includesEduardo Habkost
Some typedefs and macros are defined after the type check macros. This makes it difficult to automatically replace their definitions with OBJECT_DECLARE_TYPE. Patch generated using: $ ./scripts/codeconverter/converter.py -i \ --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]') which will split "typdef struct { ... } TypedefName" declarations. Followed by: $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \ $(git grep -l '' -- '*.[ch]') which will: - move the typedefs and #defines above the type check macros - add missing #include "qom/object.h" lines if necessary Reviewed-by: Daniel P.

2019-12-17ppc/pnv: Fix OCC common area region mappingCédric Le Goater
The OCC common area is mapped at a unique address on the system and each OCC is assigned a segment to expose its sensor data : ------------------------------------------------------------------------- | Start (Offset from | End | Size |Description | | BAR2 base address) | | | | ------------------------------------------------------------------------- | 0x00580000 | 0x005A57FF |150kB |OCC 0 Sensor Data Block| | 0x005A5800 | 0x005CAFFF |150kB |OCC 1 Sensor Data Block| | : | : | : | : | | 0x00686800 | 0x006ABFFF |150kB |OCC 7 Sensor Data Block| | 0x006AC000 | 0x006FFFFF |336kB |Reserved | ------------------------------------------------------------------------- Maximum size is 1.5MB. We could define a "OCC common area" memory region at the machine level and sub regions for each OCC. But it adds some extra complexity to the models. Fix the current layout with a simpler model.

2017-04-26ppc/pnv: Add OCC model stub with interrupt supportBenjamin Herrenschmidt
The OCC is an on-chip microcontroller based on a ppc405 core used for various power management tasks. It comes with a pile of additional hardware sitting on the PIB (aka XSCOM bus). At this point we don't emulate it (nor plan to do so). However there is one facility which is provided by the surrounding hardware that we do need, which is the interrupt generation facility. OPAL uses it to send itself interrupts under some circumstances and there are other uses around the corner. So this implement just enough to support this.
