d7fe639cab hw/nvme: add new command abort case
NVMe command set specification for end-to-end data protection formatted
namespace states:

    o If the Reference Tag Check bit of the PRCHK field is set to ‘1’ and
      the namespace is formatted for Type 3 protection, then the
      controller:
          ▪ should not compare the protection Information Reference Tag
            field to the computed reference tag; and
          ▪ may ignore the ILBRT and EILBRT fields. If a command is
            aborted as a result of the Reference Tag Check bit of the
            PRCHK field being set to ‘1’, then that command should be
            aborted with a status code of Invalid Protection Information,
            but may be aborted with a status code of Invalid Field in
            Command.

Currently qemu compares reftag in the nvme_dif_prchk function whenever
Reference Tag Check bit is set in the command. For type 3 namespaces
however, caller of nvme_dif_prchk - nvme_dif_check does not increment
reftag for each subsequent logical block. That way commands incorporating
more than one logical block for type 3 formatted namespaces with reftag
check bit set, always fail with End-to-end Reference Tag Check Error.
Comply with spec by handling case of set Reference Tag Check
bit in the type 3 formatted namespace.

fbba243bc7 hw/nvme: bump firmware revision
The Linux kernel quirks the QEMU NVMe controller pretty heavily because
of the namespace identifier mess. Since this is now fixed, bump the
firmware revision number to allow the quirk to be disabled for this
revision.

As of now, bump the firmware revision number to be equal to the QEMU
release version number.

bd9f371c6f hw/nvme: do not auto-generate uuid
Do not default to generate an UUID for namespaces if it is not
explicitly specified.

This is a technically a breaking change in behavior. However, since the
UUID changes on every VM launch, it is not spec compliant and is of
little use since the UUID cannot be used reliably anyway and the
behavior prior to this patch must be considered buggy.

36d83272d5 hw/nvme: do not auto-generate eui64
We cannot provide auto-generated unique or persistent namespace
identifiers (EUI64, NGUID, UUID) easily. Since 6.1, namespaces have been
assigned a generated EUI64 of the form "52:54:00:<namespace counter>".
This is will be unique within a QEMU instance, but not globally.

Revert that this is assigned automatically and immediately deprecate the
compatibility parameter. Users can opt-in to this with the
`eui64-default=on` device parameter or set it explicitly with
`eui64=UINT64`.

ec8c293678 hw/s390x/s390-virtio-ccw: Improve the machine description string
The machine name already contains the words "ccw" and "virtio", so
using "VirtIO-ccw" in the description likely does not really help
the average user to get an idea what this machine type is about.
Thus let's switch to "Virtual s390x machine" now, since "virtual
machine" should be a familiar term, and "s390x" signals that this
is about 64-bit guests (unlike S390 which could mean that it is
31-bit only).
Also expand "v" to "version", since this makes it easier to use
this macro also with non-numeric machine names in downstream.

5079892df5 hppa: Fix serial port assignments and pass-through
This fixes the serial ports in the emulation to behave as on original
hardware.

On the real hardware, the LASI UART is serial port #0 and the DINO UART
is serial port #1. This is fixed in SeaBIOS-hppa firmware v6, which is
why at least this firmware version is required.

The serial port addresses in hppa/hppa_hardware.h have to be swapped,
and when creating the virtual serial ports the correct port addresses
are used.

This patch now for example allows to specify on the qemu command line:
     -serial mon:stdio -serial /dev/ttyS4
to use the emulated ttyS0 in the guest for console output, and pass
ttyS4 from the host to ttyS1 in the guest.

We were somehow lucky: the TCTXT registers being touched are
TCTXT_ENx/_SET/_RESET to enable physical threads and the PC registers
at the same offset are either not used by our model or the update was
harmless.

5bb55f3e3b spapr: Use address from elf parser for kernel address
tl;dr: This allows Big Endian zImage booting via -kernel + x-vof=on.

QEMU loads the kernel at 0x400000 by default which works most of
the time as Linux kernels are relocatable, 64bit and compiled with "-pie"
(position independent code). This works for a little endian zImage too.

However a big endian zImage is compiled without -pie, is 32bit, linked to
0x4000000 so current QEMU ends up loading it at
0x4400000 but keeps spapr->kernel_addr unchanged so booting fails.

This uses the kernel address returned from load_elf().
If the default kernel_addr is used, there is no change in behavior (as
translate_kernel_address() takes care of this), which is:
LE/BE vmlinux and LE zImage boot, BE zImage does not.
If the VM created with "-machine kernel-addr=0,x-vof=on", then QEMU
prints a warning and BE zImage boots.

Note #1: SLOF (x-vof=off) still cannot boot a big endian zImage as
SLOF enables MSR_SF for everything loaded by QEMU and this leads to early
crash of 32bit zImage.

Note #2: BE/LE vmlinux images set MSR_SF in early boot so these just work;
a LE zImage restores MSR_SF after every CI call and we are lucky enough
not to crash before the first CI call.

f73eb9484b pseries: allow setting stdout-path even on machines with a VGA
-machine graphics=off is the usual way to tell the firmware or the OS that the
user wants a serial console.  The pseries machine however does not support
this, and never adds the stdout-path node to the device tree if a VGA device
is provided.  This is in addition to the other magic behavior of VGA devices,
which is to add a keyboard and mouse to the default USB bus.

Split spapr->has_graphics in two variables so that the two behaviors can be
separated: the USB devices remains the same, but the stdout-path is added
even with "-device VGA -machine graphics=off".

758c925ee0 ide_ioport_read: Return lower octet of data register instead of 0xFF
Prior to this patch, the pre-GRUB Solaris x86 bootloader would fail to
load on QEMU with the following screen output:

SunOS Secondary Boot version 3.00

prom_panic: Could not mount filesystem.
Entering boot debugger:
[136419]: _

This occurs because the bootloader issues an ATA IDENTIFY DEVICE
command, and then reads the resulting 256 words of parameter
information using inb rather than the correct inw. As the previous
behavior of QEMU was to return 0xFF and not advance the drive's sector
buffer, DRQ would never be cleared and the bootloader would be blocked
from selecting a secondary ATA device, such as an optical drive.

6827ff20b2 hw: aspeed: Init all UART's with serial devices
Background:

AspeedMachineClass.uart_default specifies the serial console UART, which
usually corresponds to the "stdout-path" in the device tree.

The default value is UART5, since most boards use UART5 for this:

    amc->uart_default = ASPEED_DEV_UART5;

Users can override AspeedMachineClass.uart_default in their board's machine
class init to specify something besides UART5. For example, for fuji-bmc:

    amc->uart_default = ASPEED_DEV_UART1;

We only connect this one UART, of the 5 UART's on the AST2400 and AST2500
and the 13 UART's on the AST2600 and AST1030, to a serial device that QEMU
users can use. None of the other UART's are initialized, and the only way
to override this attribute is by creating a specialized board definition,
requiring QEMU source code changes and rebuilding.

The result of this is that if you want to get serial console output on a
board that uses UART3, you need to add a board definition. This was
encountered by Zev in OpenBMC. [1]

Changes:

This commit initializes all of the UART's present on each Aspeed chip with
serial devices and allows the QEMU user to connect as many or few as they
like to serial devices. For example, you can still run QEMU and just connect
stdout to the machine's default UART, without specifying any additional
serial devices:

    qemu-system-arm -machine fuji-bmc \
        -drive file=fuji.mtd,format=raw,if=mtd \
        -nographic

However, if you don't want to add a special machine definition, you can now
manually configure UART1 to connect to stdout and get serial console output,
even if the machine's default is UART5:

    qemu-system-arm -machine ast2600-evb \
        -drive file=fuji.mtd,format=raw,if=mtd \
        -serial null -serial mon:stdio -display none

In the example above, the first "-serial null" argument is connected to
UART5, and "-serial mon:stdio" is connected to UART1.

Another example: you can get serial console output from Wedge100, which uses
UART3, by reusing the palmetto AST2400 machine and rewiring the serial
device arguments:

    qemu-system-arm -machine palmetto-bmc \
        -drive file=wedge100.mtd,format=raw,if=mtd \
        -serial null -serial null -serial null \
        -serial mon:stdio -display none

There is a slight change in behavior introduced with this change: now, each
UART's memory-mapped IO region will have a serial device model connected to
it. Previously, all reads and writes to those regions would be ineffective
and return zero values, but now some values will be nonzero, even when the
user doesn't connect a serial device backend (like a socket, file, etc). For
example, the line status register might indicate that the transmit buffer is
empty now, whereas previously it might have always indicated it was full.

94d10f4210 hw: aspeed: Ensure AST1030 respects uart-default
The AST1030 machine initialization was not respecting the Aspeed SoC
property "uart-default", which specifies which UART should be connected to
the first serial device, it was just always connecting UART5. This doesn't
change any behavior, because the default value for "uart-default" is UART5,
but it makes it possible to override this in new machine definitions using
the AST1030.

91a3387dc4 hw/riscv: Make CPU config error handling generous (sifive_e/u/opentitan)
If specified CPU configuration is not valid, not just it prints error
message, it aborts and generates core dumps (depends on the operating
system).  This kind of error handling should be used only when a serious
runtime error occurs.

This commit makes error handling on CPU configuration more generous on
sifive_e/u and opentitan machines.  It now just prints error message and
quits (without coredumps and aborts).

This is separate from spike/virt because it involves different type
(TYPE_RISCV_HART_ARRAY) on sifive_e/u and opentitan machines.

9598c1bb39 ptimer: Rename PTIMER_POLICY_DEFAULT to PTIMER_POLICY_LEGACY
The traditional ptimer behaviour includes a collection of weird edge
case behaviours.  In 2016 we improved the ptimer implementation to
fix these and generally make the behaviour more flexible, with
ptimers opting in to the new behaviour by passing an appropriate set
of policy flags to ptimer_init().  For backwards-compatibility, we
defined PTIMER_POLICY_DEFAULT (which sets no flags) to give the old
weird behaviour.

This turns out to be a poor choice of name, because people writing
new devices which use ptimers are misled into thinking that the
default is probably a sensible choice of flags, when in fact it is
almost always not what you want.  Rename PTIMER_POLICY_DEFAULT to
PTIMER_POLICY_LEGACY and beef up the comment to more clearly say that
new devices should not be using it.

The code-change part of this commit was produced by
  sed -i -e 's/PTIMER_POLICY_DEFAULT/PTIMER_POLICY_LEGACY/g' $(git grep -l PTIMER_POLICY_DEFAULT)
with the exception of a test name string change in
tests/unit/ptimer-test.c which was added manually.
