Error classes other than ERROR_CLASS_GENERIC_ERROR should not be used
in new code. Hiding them in QERR_ macros makes new uses hard to spot.
Fortunately, there's just one such macro left. Eliminate it with this
coccinelle semantic patch:
@@
expression EP, E;
@@
-error_set(EP, QERR_DEVICE_NOT_FOUND, E)
+error_set(EP, ERROR_CLASS_DEVICE_NOT_FOUND, "Device '%s' not found", E)
Backports commit 75158ebbe259f0bd8bf435e8f4827a43ec89c877 from qemu
We require a C99 compiler, so let's use 'bool' instead of 'int'
when dealing with boolean values. There are few enough clients
to fix them all in one pass.
Backports commit fc48ffc39ed1060856475e4320d5896f26c945e8 from qemu
Commit 8074264 (qom: Add description field in ObjectProperty struct)
introduced property descriptions and copied them for alias properties.
Instead of using the caller-supplied property name, use the returned
property name for setting the description. This avoids an Error when
setting a property description for a property with literal "[*]" that
doesn't exist due to automatic property naming in object_property_add().
Backports commit a18bb417e954ceea0a30b46c38b0d58c3a7ca6a1 from qemu
This commit fixes the following issues:
- Any unmapped/free'd memory regions (MemoryRegion instances) are not
removed from the object property linked list of its owner (which is
always qdev_get_machine(uc)). This issue makes adding new memory
mapping by calling mem_map() or mem_map_ptr() slower as more and more
memory pages are mapped and unmapped - yes, even if those memory pages
are unmapped, they still impact the speed of future memory page
mappings due to this issue.
- FlatView is not reconstructed after a memory region is freed during
unmapping, which leads to a use-after-free the next time a new memory
region is mapped in address_space_update_topology().
