Handlers don't need to modify the IDEDMA structure.
Make it const.

From: Pavel Dovgalyuk <pavel.dovgaluk@gmail.com>

Windows guest sometimes makes DMA requests with overlapping
target addresses. This leads to the following structure of iov for
the block driver:

addr size1
addr size2
addr size3

It means that three adjacent disk blocks should be read into the same
memory buffer. Windows does not expects anything from these bytes
(should it be data from the first block, or the last one, or some mix),
but uses them somehow. It leads to non-determinism of the guest execution,
because block driver does not preserve any order of reading.

This situation was discusses in the mailing list at least twice:
https://lists.gnu.org/archive/html/qemu-devel/2010-09/msg01996.html
https://lists.gnu.org/archive/html/qemu-devel/2020-02/msg05185.html

This patch makes such disk reads deterministic in icount mode.
It splits the whole request into several parts. Parts may overlap,
but SGs inside one part do not overlap.
Parts that are processed later overwrite the prior ones in case
of overlapping.

Examples for different SG part sequences:

1)
A1 1000
A2 1000
A1 1000
A3 1000
->
One request is split into two.
A1 1000
A2 1000
--
A1 1000
A3 1000

2)
A1 800
A2 1000
A1 1000
->
A1 800
A2 1000
--
A1 1000

From: Sergio Lopez <slp@redhat.com>

Move the code that processes queued requests from
virtio_blk_dma_restart_bh() to its own, non-static, function. This
will allow us to call it from the virtio_blk_data_plane_start() in a
future patch.

From: Sergio Lopez <slp@redhat.com>

On restart, we were scheduling a BH to process queued requests, which
would run before starting up the data plane, leading to those requests
being assigned and started on coroutines on the main context.

This could cause requests to be wrongly processed in parallel from
different threads (the main thread and the iothread managing the data
plane), potentially leading to multiple issues.

For example, stopping and resuming a VM multiple times while the guest
is generating I/O on a virtio_blk device can trigger a crash with a
stack tracing looking like this one:

Rather than listing block/monitor from the top-level Makefile.objs, we
should instead list monitor from block/Makefile.objs.

For now, we don't have persistent bitmaps in any other formats, but
that might not be true in the future.  Make it obvious that our
incoming parameter is not necessarily a qcow2 image, and therefore is
limited to just the bdrv_dirty_bitmap_* API calls (rather than probing

From: Klaus Jensen <k.jensen@samsung.com>

The size of the BAR is 0x1000 (main registers) + 8 bytes for each
queue. Currently, the size of the BAR is calculated like so:

    n->reg_size = pow2ceil(0x1004 + 2 * (n->num_queues + 1) * 4);

Since the 'num_queues' parameter already accounts for the admin queue,
this should in any case not need to be incremented by one. Also, the
size should be initialized to (0x1000).

    n->reg_size = pow2ceil(0x1000 + 2 * n->num_queues * 4);

This, with the default value of num_queues (64), we will set aside room
for 1 admin queue and 63 I/O queues (4 bytes per doorbell, 2 doorbells
per queue).

Change the prefix of all nvme device related trace events to 'pci_nvme'
to not clash with trace events from the nvme block driver.

Pull the controller memory buffer check to its own function. The check
will be used on its own in later patches.

From: Klaus Jensen <k.jensen@samsung.com>

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")

From: Klaus Jensen <k.jensen@samsung.com>

The num_queues device paramater has a slightly confusing meaning because
it accounts for the admin queue pair which is not really optional.
Secondly, it is really a maximum value of queues allowed.

Add a new max_ioqpairs parameter that only accounts for I/O queue pairs,
but keep num_queues for compatibility.

From: Klaus Jensen <k.jensen@samsung.com>

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.

From: Roman Kagan <rvkagan@yandex-team.ru>

The width of opt_io_size in virtio_blk_config is 32bit.  However, it's
written with virtio_stw_p; this may result in value truncation, and on
big-endian systems with legacy virtio in completely bogus readings in
the guest.

Use the appropriate accessor to store it.

  To: qemu-block; +Cc: kwolf, peter.maydell, qemu-devel

From: Roman Kagan <rvkagan@yandex-team.ru>

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.

Make it easier (more visible) to maintain the limits on the blocksize
properties in sync with the respective description, by using macros both
in the code and in the description.

From: Roman Kagan <rvkagan@yandex-team.ru>

Introduce size32 property type which handles size suffixes (k, m, g)
just like size property, but is uint32_t rather than uint64_t.  It's
going to be useful for properties that are byte sizes but are inherently
32bit, like BlkConf.opt_io_size or .discard_granularity (they are
switched to this new property type in a followup commit).

The getter for size32 is left out for a separate patch as its benefit is
less obvious, and it affects test output; for now the regular uint32
getter is used.

From: Roman Kagan <rvkagan@yandex-team.ru>

It appears convenient to be able to specify physical_block_size and
logical_block_size using common size suffixes.

Teach the blocksize property setter to interpret them.  Also express the
upper and lower limits in the respective units.

From: Roman Kagan <rvkagan@yandex-team.ru>

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.

From: Roman Kagan <rvkagan@yandex-team.ru>

Add getter for size32, and use it for blocksize, too.

In its human-readable branch, it reports approximate size in
human-readable units next to the exact byte value, like the getter for
64bit size does.

Adjust the expected test output accordingly.

From: Roman Kagan <rvkagan@yandex-team.ru>

Logical and physical block sizes in QEMU are limited to 32 KiB.

This appears unnecessarily tight, and we've seen bigger block sizes
handy at times.

Lift the limitation up to 2 MiB which appears to be good enough for
everybody, and matches the qcow2 cluster size limit.

Sometimes, we want to skip some test methods for certain formats.  This

qed does not support shrinking images, so the test_small_target method
should be skipped to keep 041 passing.

The file qcow2.py was originally contributed in 2012 by Kevin Wolf,
but was not given traditional boilerplate headers at the time.  The
missing license was just rectified (commit 16306a7b39) using the
project-default GPLv2+, but as Vladimir is not at Red Hat, he did not
add a Copyright line.  All earlier contributions have come from CC'd
authors, where all but Stefan used a Red Hat address at the time of
the contribution, and that copyright carries over to the split to
qcow2_format.py (d5262c7124).

Kevin, can you add soemthing like the following to the changelog under
"Block devices"?

Emulated NVMe device (hw/block/nvme):

  * Add the max_ioqpairs device parameter. The parameter specifies the
    maximum number of supported I/O queue pairs and should be used
    instead of the num_queues parameter. num_queues is not formally
    deprecated, but the device will issue a warning if used. If neither
    num_queues or max_ioqpairs are specified, device behavior is
    unchanged from the previous default.

  * Add the msix_qsize parameter. The parameter specifies the maximum
    number of msix interrupt vectors supported by the device. If not
    specified, device behavior is unchanged from the previous default.

> Emulated NVMe device (hw/block/nvme):

>   * Add the max_ioqpairs device parameter. The parameter specifies the
>     maximum number of supported I/O queue pairs and should be used
>     instead of the num_queues parameter. num_queues is not formally

> 
>   * Add the msix_qsize parameter. The parameter specifies the maximum
>     number of msix interrupt vectors supported by the device. If not
>     specified, device behavior is unchanged from the previous default.

Sure, I've added this.
