cfcea0f9d7 esp: remove the buf and buflen parameters from get_cmd()
Now that all SCSI commands are accumulated in cmdbuf, remove the buf and buflen
parameters from get_cmd() since these always reference cmdbuf and ESP_CMDBUF_SZ
respectively.

bb0bc7bbc9 esp: accumulate SCSI commands for PDMA transfers in cmdbuf instead of pdma_buf
ESP SCSI commands are already accumulated in cmdbuf and so there is no need to
keep a separate pdma_buf buffer. Accumulate SCSI commands for PDMA transfers in
cmdbuf instead of pdma_buf so update cmdlen accordingly and change pdma_origin
for PDMA transfers to CMD which allows the PDMA origin to be removed.

This commit also removes a stray memcpy() from get_cmd() which is a no-op because
cmdlen is always zero at the start of a command.

Notionally the removal of pdma_buf from vmstate_esp_pdma also breaks migration
compatibility for the PDMA subsection until its complete removal by the end of
the series.

6cc88d6bf9 esp: remove dma_left from ESPState
The ESP device already keeps track of the remaining bytes left to transfer via
its TC (transfer counter) register which is decremented for each byte that
is transferred across the SCSI bus.

Switch the transfer logic to use the value of TC instead of dma_left and then
remove dma_left completely, adding logic to the vmstate_esp post_load() function
to transfer the old dma_left value to the TC register during migration from
older versions.

0bd005be78 esp: add vmstate_esp version to embedded ESPState
The QOM object representing ESPState is currently embedded within both the
SYSBUS_ESP and PCI_ESP devices with migration state handled by embedding
vmstate_esp within each device using VMSTATE_STRUCT.

Since the vmstate_esp fields are embedded directly within the migration
stream, the incoming vmstate_esp version_id is lost. The only version information
available is that from vmstate_sysbus_esp_scsi and vmstate_esp_pci_scsi, but
those versions represent their respective devices and not that of the underlying
ESPState.

Resolve this by adding a new version-dependent field in vmstate_sysbus_esp_scsi
and vmstate_esp_pci_scsi which stores the vmstate_esp version_id field within
ESPState to be used to allow migration from older QEMU versions.

Finally bump the vmstate_esp version to 5 to cover the upcoming ESPState changes
within this patch series.

19800265d4 hw/riscv: virt: Map high mmio for PCIe
Some peripherals require 64-bit PCI address, so let's map the high
mmio space for PCIe.

For RV32, the address is hardcoded to below 4 GiB from the highest
accessible physical address. For RV64, the base address depends on
top of RAM and is aligned to its size which is using 16 GiB for now.

RV32 supports 34-bit physical address hence the maximum RAM size
should be limited. Limit the RAM size to 10 GiB, which leaves
some room for PCIe high mmio space.

For 32-bit host, this is not needed as machine->ram_size cannot
represent a RAM size that big. Use a #if size test to only do
the size limitation for the 64-bit host.

145b299139 hw/riscv: sifive_u: Add QSPI0 controller and connect a flash
This adds the QSPI0 controller to the SoC, and connects an ISSI
25WP256 flash to it. The generation of corresponding device tree
source fragment is also added.

Since the direct memory-mapped mode is not supported by the SiFive
SPI model, the <reg> property does not populate the second group
which represents the memory mapped address of the SPI flash.

With this commit, upstream U-Boot for the SiFive HiFive Unleashed
board can boot on QEMU 'sifive_u' out of the box. This allows users
to develop and test the recommended RISC-V boot flow with a real
world use case: ZSBL (in QEMU) loads U-Boot SPL from SPI flash to
L2LIM, then U-Boot SPL loads the payload from SPI flash that is
combined with OpenSBI fw_dynamic firmware and U-Boot proper.

Specify machine property `msel` to 6 to allow booting from the SPI
flash. U-Boot spl is directly loaded via `-bios`, and subsequent
payload is stored in the SPI flash image. Example command line:

$ qemu-system-riscv64 -nographic -M sifive_u,msel=6 -smp 5 -m 8G \
    -bios u-boot-spl.bin -drive file=spi-nor.img,if=mtd

10509e1095 hw/block: m25p80: Add ISSI SPI flash support
This adds the ISSI SPI flash support. The number of dummy cycles in
fast read, fast read dual output and fast read quad output commands
is currently using the default 8. Likewise, the same default value
is used for fast read dual/quad I/O command. Per the datasheet [1],
the number of dummy cycles is configurable, but this is not modeled
at present.

For flash whose size is larger than 16 MiB, the sequence of 3-byte
address along with EXTADD bit in the bank address register (BAR) is
not supported. We assume that guest software always uses op codes
with 4-byte address sequence. Fortunately, this is the case for both
U-Boot and Linux spi-nor drivers.

QPI (Quad Peripheral Interface) that supports 2-cycle instruction
has different default values for dummy cycles of fast read family
commands, and is unsupported at the time being.

d6cd66311f vfio-ccw: Do not read region ret_code after write
A pwrite() call returns the number of bytes written (or -1 on error),
and vfio-ccw compares this number with the size of the region to
determine if an error had occurred or not.

If they are not equal, this is a failure and the errno is used to
determine exactly how things failed. An errno of zero is possible
(though unlikely) in this situation and would be translated to a
successful operation.

If they ARE equal, the ret_code field is read from the region to
determine how to proceed. While the kernel sets the ret_code field
as necessary, the region and thus this field is not "written back"
to the user. So the value can only be what it was initialized to,
which is zero.

So, let's convert an unexpected length with errno of zero to a
return code of -EFAULT, and explicitly set an expected length to
a return code of zero. This will be a little safer and clearer.

151fcdfd62 virtio-ccw: commands on revision-less devices
The virtio standard specifies that any non-transitional device must
reject commands prior to revision setting (which we do). Devices
that are transitional need to assume revision 0 (legacy) if the
driver sends a non-revision-setting command first in order to
support legacy drivers. We neglected to do the latter.

Fortunately, nearly everything worked as intended anyway; the only
problem was not properly rejecting revision setting after some other
command had been issued. Easy to fix by setting revision to 0 if
we see a non-revision command on a legacy-capable revision-less
device.

Found by code inspection, not observed in the wild.

Commit  2c44220d05 ("meson: convert hw/arch*"), which migrated the old
Makefile.objs to meson.build  accidentally excluded virtio-ccw-9p.c and
thus the virtio-9p-ccw device from the build (and potentially also
included the file virtio-ccw-blk.c twice in the source set). And since
CONFIG_VIRTFS can't be used the way it was used here (see commit
2c9dce0196 ("meson: do not use CONFIG_VIRTFS")), the preconditions have
to be written differently.

1d8d014e93 vhost: simplify vhost_dev_init() fail_busyloop label
Requiring a conditional for every goto is tedious:

  if (busyloop_timeout) {
      goto fail_busyloop;
  } else {
      goto fail;
  }

Move the conditional to into the fail_busyloop label so that it's safe
to jump to this label unconditionally.

This change makes the migrate_add_blocker() error case more consistent.
It jumped to fail_busyloop unconditionally whereas the memslots limits
error case was conditional.

fb59288239 virtio-net: handle zero mac for a vdpa peer
Some mlx vdpa devices with kernels at least up to 5.11 currently present
0 as their MAC address.  This is because they have not been
  pre-configured with a MAC: they have a learning bridge and only learn
the MAC once guest is up.  Kernel patches and tools to allow programming
the MAC from host are being developed. For now - since these
combinations exist in the field - let's detect zero mac and just try to
proceed with the mac from the qemu command line.

This makes the guest use this MAC to send packets in turn teaching
the MAC to the card, and things work.

TODO:
report the actual MAC from QEMU commad line in the info message.
TODO:
detect that a (non-zero) hardware MAC does not match QEMU command line
and fail init.

782a78c9e9 scsi-disk: pass guest recoverable errors through even for rerror=stop
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).

f63c68bc0f scsi-disk: pass SCSI status to scsi_handle_rw_error
Instead of fishing it from *r->status, just pass the SCSI status
as a positive value of the second parameter and an errno as a
negative value.

d7a84021db scsi: introduce scsi_sense_from_errno()
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.
This allows us to consolidate the errno handling.
