* qdev: Introduce DEFINE_PROP_RESERVED_REGIONEric Auger2020-07-031-0/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce a new property defining a reserved region: <low address>:<high address>:<type>. This will be used to encode reserved IOVA regions. For instance, in virtio-iommu use case, reserved IOVA regions will be passed by the machine code to the virtio-iommu-pci device (an array of those). The type of the reserved region will match the virtio_iommu_probe_resv_mem subtype value: - VIRTIO_IOMMU_RESV_MEM_T_RESERVED (0) - VIRTIO_IOMMU_RESV_MEM_T_MSI (1) on PC/Q35 machine, this will be used to inform the virtio-iommu-pci device it should bypass the MSI region. The reserved region will be: 0xfee00000:0xfeefffff:1. On ARM, we can declare the ITS MSI doorbell as an MSI region to prevent MSIs from being mapped on guest side.

This also allows to make them all accept size suffixes, either via DEFINE_PROP_BLOCKSIZE or via DEFINE_PROP_SIZE32.

* qom: Drop parameter @errp of object_property_add() & friendsMarkus Armbruster2020-05-151-7/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only way object_property_add() can fail is when a property with the same name already exists. Since our property names are all hardcoded, failure is a programming error, and the appropriate way to handle it is passing &error_abort. Same for its variants, except for object_property_add_child(), which additionally fails when the child already has a parent. Parentage is also under program control, so this is a programming error, too. We have a bit over 500 callers. Almost half of them pass &error_abort, slightly fewer ignore errors, one test case handles errors, and the remaining few callers pass them to their own callers. The previous few commits demonstrated once again that ignoring programming errors is a bad idea. Of the few ones that pass on errors, several violate the Error API. The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. ich9_pm_add_properties(), sparc32_ledma_realize(), sparc32_dma_realize(), xilinx_axidma_realize(), xilinx_enet_realize() are wrong that way. When the one appropriate choice of argument is &error_abort, letting users pick the argument is a bad idea. Drop parameter @errp and assert the preconditions instead. There's one exception to "duplicate property name is a programming error": the way object_property_add() implements the magic (and undocumented) "automatic arrayification". Don't drop @errp there. Instead, rename object_property_add() to object_property_try_add(), and add the obvious wrapper object_property_add().

| | | | | | | | | | | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/qdev-properties.h triggers a recompile of some 2700 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some of the generated qapi-types-MODULE.h are included all over the place. Changing a QAPI type can trigger massive recompiling. Top scorers recompile more than 1000 out of some 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h): 6300 qapi/qapi-builtin-types.h 5700 qapi/qapi-types-run-state.h 3900 qapi/qapi-types-common.h 3300 qapi/qapi-types-sockets.h 3000 qapi/qapi-types-misc.h 3000 qapi/qapi-types-crypto.h 3000 qapi/qapi-types-job.h 3000 qapi/qapi-types-block-core.h 2800 qapi/qapi-types-block.h 1300 qapi/qapi-types-net.h Clean up headers to include generated QAPI headers only where needed. Impact is negligible except for hw/qdev-properties.h. This header includes qapi/qapi-types-block.h and qapi/qapi-types-misc.h. They are used only in expansions of property definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and DEFINE_PROP_OFF_AUTO(). Moving their inclusion from hw/qdev-properties.h to the users of these macros avoids pointless recompiles. This is how other property definition macros, such as DEFINE_PROP_NETDEV(), already work. Improves things for some of the top scorers: 3600 qapi/qapi-types-common.h 2800 qapi/qapi-types-sockets.h 900 qapi/qapi-types-misc.h 2200 qapi/qapi-types-crypto.h 2100 qapi/qapi-types-job.h 2100 qapi/qapi-types-block-core.h 270 qapi/qapi-types-block.h Signed-off-by: Markus Armbruster <armbru@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Tested-by: Philippe Mathieu-Daudé <philmd@redhat.com> Message-Id: <20190812052359.30071-3-armbru@redhat.com>

| | | | | | | | | | | | | | | | | | | | | A link property can be set during creation, with object_property_add_link() and later with object_property_set_link(). add_link() doesn't add a reference to the target object, while set_link() does. Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link, says whether a reference must be released when the property is destroyed. This can lead to leaks if the property was later set_link(), as the added reference is never released. Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG and use that has an indication on how the link handle reference management in set_link().

* | qdev: fix the order compat and global properties are appliedGreg Kurz2017-07-171-13/+2Star
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code recursively applies global properties from child up to parent types. This can cause properties passed with the -global option to be silently overridden by internal compat properties. This is exactly what happened with virtio-*-pci drivers since commit: "9a4c0e220d8a hw/virtio-pci: fix virtio behaviour" Passing -device virtio-blk-pci.disable-modern=off had no effect on 2.6 machine types because the internal virtio-pci.disable-modern=on compat property always prevailed. A workaround for this was included with commit 0bcba41f ("machine: Convert abstract typename on compat_props to subclass names"). This patch fixes the issue properly by reversing the logic: we now go through the global property list and, for each property, we check if it is applicable to the device. This results in compat properties being applied first, in the order they appear in the HW_COMPAT_* macros, followed by global properties, in the order they appear on the command line.
