2020-09-02hw/block/nvme: add support for the abort commandKlaus Jensen
Required for compliance with NVMe revision 1.3d. See NVM Express 1.3d, Section 5.1 ("Abort command"). The Abort command is a best effort command; for now, the device always fails to abort the given command.

Currently we have a SWIM typedef and a SWIM type checking macro, but OBJECT_DECLARE* would transform the SWIM macro into a function, and the function name would conflict with the SWIM typedef name.

Automatically size the number of virtio-blk-pci request virtqueues to match the number of vCPUs. Other transports continue to default to 1 request virtqueue.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini
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.

2020-07-21qom: Change object_get_canonical_path_component() not to mallocMarkus Armbruster
object_get_canonical_path_component() returns a malloced copy of a property name on success, null on failure. 19 of its 25 callers immediately free the returned copy. Change object_get_canonical_path_component() to return the property name directly. Since modifying the name would be wrong, adjust the return type to const char *. Drop the free from the 19 callers become simpler, add the g_strdup() to the other six.

2020-07-10xen: Use ERRP_GUARD()Vladimir Sementsov-Ogievskiy
If we want to check error after errp-function call, we need to introduce local_err and then propagate it to errp. Instead, use the ERRP_GUARD() macro, benefits are: 1. No need of explicit error_propagate call 2. No need of explicit local_err variable: use errp directly 3. ERRP_GUARD() leaves errp as is if it's not NULL or &error_fatal, this means that we don't break error_abort (we'll abort on error_set, not on error_propagate) If we want to add some info to errp (by error_prepend() or error_append_hint()), we must use the ERRP_GUARD() macro. Otherwise, this info will not be added when errp == &error_fatal (the program will exit prior to the error_append_hint() or error_prepend() call). No such cases are being fixed here.

The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable(). Silently fails to convert hw/arm/armsse.c, because Coccinelle gets confused by ARMSSE being used both as typedef and function-like macro there. Converted manually. Line breaks tidied up manually.

2020-06-23fdc: Reject clash between -drive if=floppy and -global isa-fdcMarkus Armbruster
The floppy controller devices desugar their drive properties into floppy devices (since commit a92bd191a4 "fdc: Move qdev properties to FloppyDrive", v2.8.0). This involves some bad magic in fdctrl_connect_drives(), and exists for backward compatibility. The functions for boards to create floppy controller devices fdctrl_init_isa(), fdctrl_init_sysbus(), and sun4m_fdctrl_init() desugar -drive if=floppy to these floppy controller drive properties. If you use both -drive if=floppy (or its -fda / -fdb sugar) and -global isa-fdc for the same floppy device, -global silently loses the conflict, and both backends involved end up with the floppy device frontend attached, as demonstrated by iotest 172 (see commit before previous). This is wrong. Desugar -drive if=floppy straight to floppy devices instead, with helper fdctrl_init_drives(). The conflict now gets rejected cleanly: first, fdctrl_connect_drives() creates the floppy for the controller's property, then fdctrl_init_drives() attempts to create the floppy for -drive if=floppy, but fails because the unit is already in use. Output of iotest 172 changes in three ways: 1. The clash gets rejected. 2. In one test case, "info qtree" has the floppy devices swapped, and "info block" has their QOM paths swapped. This is because the floppy device for -fda now gets created after the one for -global isa-fdc.driveB. 3. The error message for -global floppy.drive=floppy0 changes. Before the patch, we set isa-fdc.driveA to -fda's block backend, then create the floppy device for it, then move the backend from isa-fdc.driveA to floppy.drive. Floppy creation fails when applying -global floppy.drive=floppy0, because floppy0 is still attached to isa-fdc. After the patch, we create the floppy for -fda, then set its drive property to floppy0. Now floppy creation succeeds, but setting the drive property fails, because -global already set it. Yes, this is exasperatingly complicated.

2020-06-17block: make BlockConf size props 32bit and accept size suffixesRoman Kagan
Convert all size-related properties in BlockConf to 32bit. This will accommodate bigger block sizes (in a followup patch). This also allows to make them all accept size suffixes, either via DEFINE_PROP_BLOCKSIZE or via DEFINE_PROP_SIZE32. Also, since min_io_size is exposed to the guest by scsi and virtio-blk devices as an uint16_t in units of logical blocks, introduce an additional check in blkconf_blocksizes to prevent its silent truncation.

2020-06-17block: consolidate blocksize properties consistency checksRoman Kagan
Several block device properties related to blocksize configuration must be in certain relationship WRT each other: physical block must be no smaller than logical block; min_io_size, opt_io_size, and discard_granularity must be a multiple of a logical block. To ensure these requirements are met, add corresponding consistency checks to blkconf_blocksizes, adjusting its signature to communicate possible error to the caller. Also remove the now redundant consistency checks from the specific devices.

2020-06-17hw/block/nvme: add msix_qsize parameterKlaus Jensen
Decouple the requested maximum number of ioqpairs (param max_ioqpairs) from the number of MSI-X interrupt vectors by introducing a new msix_qsize parameter and initialize MSI-X with that. This allows emulating a device that has fewer vectors than I/O queue pairs and also allows more than 2048 queue pairs. To keep the device behaving as previously, use a msix_qsize default of 65 (default max_ioqpairs + 1). This decoupling was actually suggested by Maxim some time ago in a slightly different context, so adding a Suggested-by.

2020-06-17hw/block/nvme: fix pin-based interrupt behaviorKlaus Jensen
First, since the device only supports MSI-X or pin-based interrupt, if MSI-X is not enabled, it should not accept interrupt vectors different from 0 when creating completion queues. Secondly, the irq_status NvmeCtrl member is meant to be compared to the INTMS register, so it should only be 32 bits wide. And it is really only useful when used with multi-message MSI. Third, since we do not force a 1-to-1 correspondence between cqid and interrupt vector, the irq_status register should not have bits set according to cqid, but according to the associated interrupt vector. Fix these issues, but keep irq_status available so we can easily support multi-message MSI down the line. Fixes: 5e9aa92eb1a5 ("hw/block: Fix pin-based interrupt behaviour of NVMe") Cc: "Michael S.
