iotests.py: Add qemu_io_silent

qemu-io: Exit with error when a command failed
Currently, qemu-io basically always returns success when it gets to
interactive mode (so once the whole command line has been parsed; even
before the commands on the command line are interpreted). That is not
very useful.
This patch makes qemu-io return failure when any of the executed
commands failed.

qemu-io: Drop command functions' return values
For qemu-io, a function returns an integer with two possible values: 0
for "qemu-io may continue execution", or 1 for "qemu-io should exit".
However, there is only a single command that returns 1, and that is
"quit".
So let's turn this case into a global variable instead so we can make
better use of the return value in a later patch.

This adds a test for an I/O error during snapshot deletion, and maybe

qcow2: Repair OFLAG_COPIED when fixing leaks
Repairing OFLAG_COPIED is usually safe because it is done after the
refcounts have been repaired. Therefore, it we did not find anyone else
referencing a data or L2 cluster, it makes no sense to not set
OFLAG_COPIED -- and the other direction (clearing OFLAG_COPIED) is
always safe, anyway, it may just induce leaks.
Furthermore, if OFLAG_COPIED is actually consistent with a wrong (leaky)
refcount, we will decrement the refcount with -r leaks, but OFLAG_COPIED
will then be wrong. qemu-img check should not produce images that are
more corrupted afterwards then they were before.

iotests: Rework 113
This test case has been broken since
398e6ad014df261d (roughly half a
year). qemu-img amend requires its output image to be R/W, so it opens
it as such; the node is then turned into an read-only node automatically
which is now accompanied by a warning, however. This warning has not
been part of the reference output.
For one thing, this warning shows that we cannot keep the test case as
it is. We would need a format that has no create_opts but that does
have write support -- we do not have such a format, though.
Another thing is that qemu now actually checks whether an image format
supports amendment instead of whether it has create_opts (since the
former always implies the latter). So we can now use any format that
does not support amendment (even if it supports creation) and thus test
the same code path.
The reason nobody has noticed the breakage until now of course is the
fact that nobody runs the iotests for nbd+bochs. There actually was
never any reason to set the protocol to "nbd" but because that was
technically correct; functionally it made no difference. So that is the
first thing we are going to change: Make the protocol "file" instead so
that people might actually notice breakage here.
Secondly, now that bochs no longer works for the amend test case, we
have to change the format there anyway. Set let us just bend the truth
a bit, declare this test a raw test. In fact, that does not even
concern the bochs test cases, other than the output now reading 'bochs'
instead of 'IMGFMT'.
So with this test now being a raw test, we can rework the amend test
case to use raw instead.

The only users of print_block_option_help() are qemu-img create and

qemu-img: Add print_amend_option_help()
The more generic print_block_option_help() function is not really
suitable for qemu-img amend, for a couple of reasons:
(1) We do not need to append the protocol-level options, as amendment
happens only on one node and does not descend downwards to its
children.
(2) print_block_option_help() says those options are "supported". For
option amendment, we do not really know that. So this new function
explicitly says that those options are the creation options, and not
all of them may be supported.
(3) If the driver does not support option amendment, we should not print
anything (except for an error message that amendment is not
supported).

ahci: move PIO Setup FIS before transfer, fix it for ATAPI commands
The PIO Setup FIS is written in the PIO:Entry state, which comes before
the ATA and ATAPI data transfer states. As a result, the PIO Setup FIS
interrupt is now raised before DMA ends for ATAPI commands, and tests have
to be adjusted.
This is also hinted by the description of the command header in the AHCI
specification, where the "A" bit is described as
When ‘1’, indicates that a PIO setup FIS shall be sent by the device
indicating a transfer for the ATAPI command.
and also by the description of the ACMD (ATAPI command region):
The ATAPI command must be either 12 or 16 bytes in length. The length
transmitted by the HBA is determined by the PIO setup FIS that is sent
by the device requesting the ATAPI command.
QEMU, which conflates the "generator" and the "receiver" of the FIS into
one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.

libqos/ahci: track sector size
It's not always 512, and it does wind up mattering for PIO tranfers,
because this means DRQ blocks are four times as big for ATAPI.
Replace an instance of 2048 with the correct define, too.
This patch by itself winds changing no behavior. fis->count is ignored
for CMD_PACKET, and sect_count only gets used in non-ATAPI cases.

ahci: fix PxCI register race
Fixes: https://bugs.launchpad.net/qemu/+bug/
1769189
AHCI presently signals completion prior to the PxCI register being
cleared to indicate completion. If a guest driver attempts to issue
a new command in its IRQ handler, it might be surprised to learn there
is still a command pending.
In the case of Windows 10's boot driver, it will actually poll the IRQ
register hoping to find out when the command is done running -- which
will never happen, as there isn't a command running.
Fix this: clear PxCI in ahci_cmd_done and not in the asynchronous BH.
Because it now runs synchronously, we don't need to check if the command
is actually done by spying on the ATA registers. We know it's done.

sdcard: Update the Configuration Register (SCR) to Spec Version 1.10
The initial implementation is based on the Specs v1.10 (see
a1bb27b1e98).
However the SCR is anouncing the card being v1.01.
The new chapters added in version 1.10 are:
4.3.10 Switch function command
Switch function command (CMD6) 1 is used to switch or expand
memory card functions. [...]
This is a new feature, introduced in SD physical Layer
Specification Version 1.10. Therefore, cards that are
compatible with earlier versions of the spec do not support
it. The host shall check the "SD_SPEC" field in the SCR
register to recognize what version of the spec the card
complies with before using CMD6. It is mandatory for SD
memory card of Ver1.10 to support CMD6.
4.3.11 High-Speed mode (25MB/sec interface speed)
Though the Rev 1.01 SD memory card supports up to 12.5MB/sec
interface speed, the speed of 25MB/sec is necessary to support
increasing performance needs of the host and because of memory
size which continues to grow.
To achieve 25MB/sec interface speed, clock rate is increased to
50MHz and CLK/CMD/DAT signal timing and circuit conditions are
reconsidered and changed from Physical Layer Specification
Version 1.01.
4.3.12 Command system (This chapter is newly added in version 1.10)
SD commands CMD34-37, CMD50, CMD57 are reserved for SD command
system expansion via the switch command.
[These commands] will be considered as illegal commands (as
defined in revision 1.01 of the SD physical layer specification).
The SWITCH_FUNCTION is implemented since the first commit,
a1bb27b1e98.
The 25MB/sec High-Speed mode was already updated in
d7ecb867529.
The current implementation does not implements CMD34-37, CMD50 and
CMD57, thus these commands already return ILLEGAL.
With this patch, the SCR register now matches the description of the header:
* SD Memory Card emulation as defined in the "SD Memory Card Physical
* layer specification, Version 1.10."

While we skip the GIC_INTERNAL irqs, we don't change the register offset
accordingly. This will overlap the GICR registers value and leave the

Fix this by skipping the registers banked by GICR.
Also for migration compatibility if the migration source (old version
qemu) doesn't send gicd_no_migration_shift_bug = 1 to destination, then
we shift the data of PPI to get the right data for SPI.
