This workaround is no longer required with the current code and so can be
removed.
[Note: whilst MacOS itself can boot correctly, removing this hack prevents
a bootable EMILE CDROM from working. This is caused by a separate bug which
will be fixed by a subsequent patch]

Following on from the recent changes to when the TC is updated, it is now
possible to remove another set of manual STAT_TC updates so that its state
is now managed within esp_set_tc().

The fifo8_pop_buf() function returns a pointer to the FIFO buffer up to the
specified length. Since the FIFO buffer is modelled as an array then once
the FIFO wraps around, only the continuous portion of the buffer can be
returned.
In future the use of continuous and unaligned accesses will advance the
internal FIFO head pointer, so modify esp_fifo_pop_buf() to ensure that
any wraparound content is also returned up to the requested length.

Load the 64-bit SeaBIOS-hppa firmware by default when running on a 64-bit
machine. This will enable us to later support more than 4GB of RAM and is
required that the OS (or PALO bootloader) will start or install a 64-bit kernel
instead of a 32-bit kernel.
Note that SeaBIOS-hppa v16 provides the "-fw_cfg opt/OS64,string=3" option with
which the user can control what the firmware shall report back to the OS:
Support of 32-bit OS, support of a 64-bit OS, or support for both (default).
Wrap firmware loading inside !qtest_enabled() to avoid this warning with
qtest: "qemu-system-hppa: no firmware provided".

Netbsd isn't able to detect a link on the emulated tulip card. That's
because netbsd reads the Chip Status Register of the Phy (address
0x14). The default phy data in the qemu tulip driver is all zero,
which means no link is established and autonegotation isn't complete.
Therefore set the register to 0x3b40, which means:
Link is up, Autonegotation complete, Full Duplex, 100MBit/s Link
speed.
Also clear the mask because this register is read only.

The Astro/Elroy chip can work in either Hard-Fail or Soft-Fail mode.
Hard fail means the system bus will send an HPMC (=crash) to the
processor, soft fail means the system bus will ignore timeouts of
MMIO-reads or MMIO-writes and return -1ULL.
The HF mode is controlled by a bit in the status register and is usually
programmed by the OS. Return the corresponing values based on the current
value of that bit.

For RISC-V the SMBIOS standard requires specific values of the processor
family value depending on the bitness of the CPU.
Add a processor-family option for SMBIOS table 4.
The value of processor-family may exceed 255 and therefore must be provided
in the Processor Family 2 field. Set the Processor Family field to 0xFE
which signals that the Processor Family 2 is used.

A few months ago I submitted a patch to various lists, deprecating
"riscv,isa" with a lengthy commit message [0] that is now commit
aeb71e42caae ("dt-bindings: riscv: deprecate riscv,isa") in the Linux
kernel tree. Primarily, the goal was to replace "riscv,isa" with a new
set of properties that allowed for strictly defining the meaning of
various extensions, where "riscv,isa" was tied to whatever definitions
inflicted upon us by the ISA manual, which have seen some variance over
time.
Two new properties were introduced: "riscv,isa-base" and
"riscv,isa-extensions". The former is a simple string to communicate the
base ISA implemented by a hart and the latter an array of strings used
to communicate the set of ISA extensions supported, per the definitions
of each substring in extensions.yaml [1]. A beneficial side effect was
also the ability to define vendor extensions in a more "official" way,
as the ISA manual and other RVI specifications only covered the format
for vendor extensions in the ISA string, but not the meaning of vendor
extensions, for obvious reasons.
Add support for setting these two new properties in the devicetrees for
the various devicetree platforms supported by QEMU for RISC-V. The Linux
kernel already supports parsing ISA extensions from these new
properties, and documenting them in the dt-binding is a requirement for
new extension detection being added to the kernel.
A side effect of the implementation is that the meaning for elements in
"riscv,isa" and in "riscv,isa-extensions" are now tied together as they
are constructed from the same source. The same applies to the ISA string
provided in ACPI tables, but there does not appear to be any strict
definitions of meanings in ACPI land either.

We have a lot of cases where a char or an uint32_t pointer is used once
to alloc a string/array, read/written during the function, and then
g_free() at the end. There's no pointer re-use - a single alloc, a
single g_free().
Use 'g_autofree' to avoid the g_free() calls.

Requests that complete in an IOThread use irqfd to notify the guest
while requests that complete in the main loop thread use the traditional
qdev irq code path. The reason for this conditional is that the irq code
path requires the BQL:
if (s->ioeventfd_started && !s->ioeventfd_disabled) {
virtio_notify_irqfd(vdev, req->vq);
} else {
virtio_notify(vdev, req->vq);
}
There is a corner case where the conditional invokes the irq code path
instead of the irqfd code path:
static void virtio_blk_stop_ioeventfd(VirtIODevice *vdev)
{
...
/*
* Set ->ioeventfd_started to false before draining so that host notifiers
* are not detached/attached anymore.
*/
s->ioeventfd_started = false;
/* Wait for virtio_blk_dma_restart_bh() and in flight I/O to complete */
blk_drain(s->conf.conf.blk);
During blk_drain() the conditional produces the wrong result because
ioeventfd_started is false.
Use qemu_in_iothread() instead of checking the ioeventfd state.

Commit d3f6f294aeadd5f88caf0155e4360808c95b3146 ("virtio-blk: always set
ioeventfd during startup") has made virtio_blk_start_ioeventfd() always
kick the virtqueue (set the ioeventfd), regardless of whether the BB is
drained. That is no longer necessary, because attaching the host
notifier will now set the ioeventfd, too; this happens either
immediately right here in virtio_blk_start_ioeventfd(), or later when
the drain ends, in virtio_blk_ioeventfd_attach().
With event_notifier_set() removed, the code becomes the same as the one
in virtio_blk_ioeventfd_attach(), so we can reuse that function.

During drain, we do not care about virtqueue notifications, which is why
we remove the handlers on it. When removing those handlers, whether vq
notifications are enabled or not depends on whether we were in polling
mode or not; if not, they are enabled (by default); if so, they have
been disabled by the io_poll_start callback.
Because we do not care about those notifications after removing the
handlers, this is fine. However, we have to explicitly ensure they are
enabled when re-attaching the handlers, so we will resume receiving
notifications. We do this in virtio_queue_aio_attach_host_notifier*().
If such a function is called while we are in a polling section,
attaching the notifiers will then invoke the io_poll_start callback,
re-disabling notifications.
Because we will always miss virtqueue updates in the drained section, we
also need to poll the virtqueue once after attaching the notifiers.

As of commit 38738f7dbbda90fbc161757b7f4be35b52205552 ("virtio-scsi:
don't waste CPU polling the event virtqueue"), we only attach an io_read
notifier for the virtio-scsi event virtqueue instead, and no polling
notifiers. During operation, the event virtqueue is typically
non-empty, but none of the buffers are intended to be used immediately.
Instead, they only get used when certain events occur. Therefore, it
makes no sense to continuously poll it when non-empty, because it is
supposed to be and stay non-empty.
We do this by using virtio_queue_aio_attach_host_notifier_no_poll()
instead of virtio_queue_aio_attach_host_notifier() for the event
virtqueue.
Commit 766aa2de0f29b657148e04599320d771c36fd126 ("virtio-scsi: implement
BlockDevOps->drained_begin()") however has virtio_scsi_drained_end() use
virtio_queue_aio_attach_host_notifier() for all virtqueues, including
the event virtqueue. This can lead to it being polled again, undoing
the benefit of commit 38738f7dbbda90fbc161757b7f4be35b52205552.
Fix it by using virtio_queue_aio_attach_host_notifier_no_poll() for the
event virtqueue.

usb-storage is for the most part just a wrapper around an internally
created scsi-disk device. It uses DEFINE_BLOCK_PROPERTIES() to offer all
of the usual block device properties to the user, but then only forwards
a few select properties to the internal device while the rest is
silently ignored.
This changes scsi_bus_legacy_add_drive() to accept a whole BlockConf
instead of some individual values inside of it so that usb-storage can
now pass the whole configuration to the internal scsi-disk. This enables
the remaining block device properties, e.g. logical/physical_block_size
or discard_granularity.
