* include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster2016-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* scsi: Clean up duplicated error in legacy if=scsi codeMarkus Armbruster2015-03-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit a818a4b changed scsi_bus_legacy_handle_cmdline() to report errors from scsi_bus_legacy_add_drive() with error_report() in addition to returning them. That's inappropriate. Two kinds of callers: 1. realize methods (devices "esp", "virtio-scsi-device" and "spapr-vscsi") The error object gets passed up the call chain until it gets reported again and freed. Example: $ qemu-system-arm -M virt -S -display none \ > -drive if=scsi,id=foo,bus=1,file=tmp.qcow2 \ > -device nec-usb-xhci -device usb-storage,drive=foo \ > -device virtio-scsi-pci qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Property 'scsi-disk.drive' can't take value 'foo', it's in use qemu-system-arm: -drive if=scsi,id=foo,bus=1,file=tmp.qcow2: Setting drive property failed qemu-system-arm: -device virtio-scsi-pci: Setting drive property failed qemu-system-arm: -device virtio-scsi-pci: Device initialization failed qemu-system-arm: -device virtio-scsi-pci: Device 'virtio-scsi-pci' could not be initialized The second message in this error cascade comes from scsi_bus_legacy_handle_cmdline(). The error object then gets passed up to the qdev_init() called from virtio_scsi_pci_init_pci(), which reports it again. 2. init methods (devices "am53c974", "dc390", "lsi53c895a", "lsi53c810", "megasas", "megasas-gen2") init methods need to report their errors with qerror_report(). These don't. The inappropriate error_report() papers over the bug. error_report() isn't the same as qerror_report() in QMP context, but this can't actually happen: QMP can still only hot-plug, and callers call scsi_bus_legacy_handle_cmdline() only on cold-plug. Except for sysbus_esp_realize(), but that can't be hot-plugged at all, as far as I can tell. Fix the init methods and drop the inappropriate error_report() in scsi_bus_legacy_handle_cmdline().

| | | | | | | | | | | | | | | | | | | | After previous Peter patch, they are redundant. This way we don't assign them except when needed. Once there, there were lots of case where the ".fields" indentation was wrong: .fields = (VMStateField []) { and .fields = (VMStateField []) { Change all the combinations to: .fields = (VMStateField[]){ The biggest problem (appart from aesthetics) was that checkpatch complained when we copy&pasted the code from one place to another.
