* scsi: drop 'result' argument from command_complete callbackHannes Reinecke2021-02-259-28/+24Star
| | | | | | | | | | The command complete callback has a SCSIRequest as the first argument, and the status field of that structure is identical to the 'status' argument. So drop the argument from the callback. Signed-off-by: Hannes Reinecke <hare@suse.de> Message-Id: <20201116184041.60465-3-hare@suse.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* scsi-disk: pass guest recoverable errors through even for rerror=stopPaolo Bonzini2021-02-251-23/+28
| | | | | | | | | | Right now, recoverable sense values are only passed directly to the guest only for rerror=report. However, when rerror/werror are 'stop' we still don't want the host to be involved on every UNIT ATTENTION (especially considered that the QMP event will not have enough information to act on the report).

* scsi: introduce scsi_sense_from_errno()Paolo Bonzini2021-02-251-37/+8Star
| | | | | | | | | | The new function is an extension of the switch statement in scsi-disk.c which also includes the errno cases only found in sg_io_sense_from_errno.

* virtio-scsi: don't process IO on fenced dataplaneMaxim Levitsky2021-02-251-9/+15
| | | | | | | | | | | | | If virtio_scsi_dataplane_start fails, there is a small window when it drops the aio lock (in aio_wait_bh_oneshot) and the dataplane's AIO handler can still run during that window. This is done after the dataplane was marked as fenced, thus we use this flag to avoid it doing any IO.

* block: Separate blk_is_writable() and blk_supports_write_perm()Kevin Wolf2021-01-272-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, blk_is_read_only() tells whether a given BlockBackend can only be used in read-only mode because its root node is read-only. Some callers actually try to answer a slightly different question: Is the BlockBackend configured to be writable, by taking write permissions on the root node? This can differ, for example, for CD-ROM devices which don't take write permissions, but may be backed by a writable image file. scsi-cd allows write requests to the drive if blk_is_read_only() returns false. However, the write request will immediately run into an assertion failure because the write permission is missing. This patch introduces separate functions for both questions. blk_supports_write_perm() answers the question whether the block node/image file can support writable devices, whereas blk_is_writable() tells whether the BlockBackend is currently configured to be writable. All calls of blk_is_read_only() are converted to one of the two new functions.

* | migration: Replace migration's JSON writer by the general oneMarkus Armbruster2020-12-191-1/+1
|/ | | | | | | | | | | | | | | | | | | Commit 8118f0950f "migration: Append JSON description of migration stream" needs a JSON writer. The existing qobject_to_json() wasn't a good fit, because it requires building a QObject to convert. Instead, migration got its very own JSON writer, in commit 190c882ce2 "QJSON: Add JSON writer". It tacitly limits numbers to int64_t, and strings contents to characters that don't need escaping, unlike qobject_to_json(). The previous commit factored the JSON writer out of qobject_to_json(). Replace migration's JSON writer by it.

* scsi-generic: Fix HM-zoned device scanDmitry Fomichev2020-09-301-4/+6
| | | | | | | | | | | | | | | | | | | | | | Several important steps during device scan depend on SCSI type of the device. For example, max_transfer property is only determined and assigned if the device has the type of TYPE_DISK. Host-managed ZBC disks retain most of the properties of regular SCSI drives, but they have their own SCSI device type, 0x14. This prevents the proper assignment of max_transfer property for HM-zoned devices in scsi-generic driver leading to I/O errors if the maximum i/o size calculated at the guest exceeds the host value. To fix this, define TYPE_ZBC to have the standard value from SCSI ZBC standard spec. Several scan steps that were previously done only for TYPE_DISK devices, are now performed for the SCSI devices having TYPE_ZBC too.

* qom: simplify object_find_property / object_class_find_propertyDaniel P. Berrangé2020-09-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | When debugging QEMU it is often useful to put a breakpoint on the error_setg_internal method impl. Unfortunately the object_property_add / object_class_property_add methods call object_property_find / object_class_property_find methods to check if a property exists already before adding the new property. As a result there are a huge number of calls to error_setg_internal on startup of most QEMU commands, making it very painful to set a breakpoint on this method. Most callers of object_find_property and object_class_find_property, however, pass in a NULL for the Error parameter. This simplifies the methods to remove the Error parameter entirely, and then adds some new wrapper methods that are able to raise an Error when needed. Signed-off-by: Daniel P.

* spapr_vscsi: do not allow device hotplugDaniel Henrique Barboza2020-09-081-0/+3
| | | | | | | | | | | | | | | | | We do not implement hotplug in the vscsi bus, but we forgot to tell qdev about it. The result is that users are able to hotplug devices in the vscsi bus, the devices appear in qdev, but they aren't usable by the guest OS unless the user reboots it first. Setting qbus hotplug_handler to NULL will tell qdev-monitor, via qbus_is_hotpluggable(), that we do not support hotplug operations in spapr_vscsi.

Other transports continue to default to 1 request virtqueue. A 1:1 virtqueue:vCPU mapping ensures that completion interrupts are handled on the same vCPU that submitted the request. No IPI is necessary to complete an I/O request and performance is improved. The maximum number of MSI-X vectors and virtqueues limit are respected.

* trace: switch position of headers to what Meson requiresPaolo Bonzini2020-08-211-0/+1
| | | | | | | | | | | | | | | | | Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.
