The newly added neoverse-n1 CPU has ID register values which indicate
the presence of the Statistical Profiling Extension, because the real
hardware has this feature. QEMU's TCG emulation does not yet
implement SPE, though (not even as a minimal stub implementation), so
guests will crash if they try to use it because the SPE system
registers don't exist.
Force ID_AA64DFR0_EL1.PMSVer to 0 in CPU realize for TCG, so that
we don't advertise to the guest a feature that doesn't exist.
(We could alternatively do this by editing the value that
aarch64_neoverse_n1_initfn() sets for this ID register, but
suppressing the field in realize means we won't re-introduce this bug
when we add other CPUs that have SPE in hardware, such as the
Neoverse-V1.)
An example of a non-booting guest is current mainline Linux (5.19),
when booting in EL2 on the virt board (ie with -machine
virtualization=on).

The latest glibc 2.36 has extended sys/mount.h so that it
defines the FSCONFIG_* enum constants. These are historically
defined in linux/mount.h, and thus if you include both headers
the compiler complains:
In file included from /usr/include/linux/fs.h:19,
from ../linux-user/syscall.c:98:
/usr/include/linux/mount.h:95:6: error: redeclaration of 'enum fsconfig_command'

In file included from ../linux-user/syscall.c:31:

191 | FSCONFIG_SET_FLAG = 0, /* Set parameter, supplying no value */

...snip...
QEMU doesn't include linux/mount.h, but it does use
linux/fs.h and thus gets linux/mount.h indirectly.
glibc acknowledges this problem but does not appear to
be intending to fix it in the forseeable future, simply
documenting it as a known incompatibility with no
workaround:
https://sourceware.org/glibc/wiki/Release/2.36#Usage_of_.3Clinux.2Fmount.h.3E_and_.3Csys.2Fmount.h.3Ehttps://sourceware.org/glibc/wiki/Synchronizing_Headers
To address this requires either removing use of sys/mount.h
or linux/fs.h, despite QEMU needing declarations from
both.
This patch removes linux/fs.h, meaning we have to define
various FS_IOC constants that are now unavailable.

hw/net/rocker: Avoid undefined shifts with more than 31 ports
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
The function icount_prepare_for_run() is called with the iothread
unlocked, but it can call icount_notify_aio_contexts() which will
run qemu timer handlers. Those are supposed to be run only with
the iothread lock held, so take the lock while we do that.
Since icount mode runs everything on a single thread anyway,
not holding the lock is likely mostly not going to introduce
races, but it can cause us to trip over assertions that we
do hold the lock, such as the one reported in issue 1130.

In rocker_port_phys_link_status() and rocker_port_phys_enable_read()
we construct a 64-bit value with one bit per front-panel port.
However we accidentally do the shift as 32-bit arithmetic, which
means that if there are more than 31 front-panel ports this is
undefined behaviour.
Fix the problem by ensuring we use 64-bit arithmetic for the whole
calculation. (We won't ever shift off the 64-bit value because
ROCKER_FP_PORTS_MAX is 62.)

In real hardware, the APB and AHB PNP data tables can be accessed
with byte and halfword reads as well as word reads. Our
implementation currently only handles word reads. Add support for
the 8 and 16 bit accesses. Note that we only need to handle aligned
accesses -- unaligned accesses should continue to trap, as happens on

QEMU crashes trying to save VMSTATE when only MIPS target are compiled in

Segmentation fault (core dumped)
It happens due to PIIX4_PM trying to parse hotplug vmstate structures
which are valid only for x86 and not for MIPS (as it requires ACPI
tables support which is not existent for ithe later)
Issue was probably exposed by trying to cleanup/compile out unused
ACPI bits from MIPS target (but forgetting about migration bits).
Disable compiled out features using compat properties as the least

The -M memory.* options do not have magic applied to them like the -m
option, namely no "M" (for mebibytes) is tacked at the end of a suffixless
value for "-M memory.size".
This magic is performed by parse_memory_options, and we have to do it for
both "-m" and the [memory] section of a config file. Storing [memory]
sections directly to machine_opts_dict changed the meaning of
[memory]
size = "1024"
in a -readconfig file from 1024MiB to 8KiB (1024 Bytes rounded up to
8KiB silently). To avoid this, the [memory] section has to be changed
back to QemuOpts (combining [memory] and "-m" will work fine thanks to
.merge_lists being true).
Change parse_memory_options() so that, similar to the older function
set_memory_options(), it operates after command line parsing is done;
and also call it where set_memory_options() used to be.
Note, the parsing code uses exit(1) instead of exit(EXIT_FAILURE) to
match neighboring code.

For accessing single blocks during boot, it's the logical block size that
matters. (Physical block sizes are rather interesting e.g. for creating
file systems with the correct alignment for speed reasons etc.).
So the s390-ccw bios has to use the logical block size for calculating
sector numbers during the boot phase, the "physical_block_exp" shift
value must not be taken into account. This change fixes the boot process
when the guest hast been installed on a disk where the logical block size
differs from the physical one, e.g. if the guest has been installed
like this:
qemu-system-s390x -nographic -accel kvm -m 2G \
-drive if=none,id=d1,file=fedora.iso,format=raw,media=cdrom \
-device virtio-scsi -device scsi-cd,drive=d1 \
-drive if=none,id=d2,file=test.qcow2,format=qcow2
-device virtio-blk,drive=d2,physical_block_size=4096,logical_block_size=512
Linux correctly uses the logical block size of 512 for the installation,
but the s390-ccw bios tries to boot from a disk with 4096 block size so
far, as long as this patch has not been applied yet (well, it used to work
by accident in the past due to the virtio_assume_scsi() hack that used to
enforce 512 byte sectors on all virtio-block disks, but that hack has been
well removed in commit 5447de2619 to fix other scenarios).
Fixes: 5447de2619 ("pc-bios/s390-ccw/virtio-blkdev: Remove virtio_assume_scsi()")

close() is a *nix function. It works on any file descriptor, and
sockets in *nix are an example of a file descriptor.
closesocket() is a Windows-specific function, which works only
specifically with sockets. Sockets on Windows do not use *nix-style
file descriptors, and socket() returns a handle to a kernel object
instead, so it must be closed with closesocket().
In QEMU there is already a logic to handle such platform difference
in os-posix.h and os-win32.h, that:
* closesocket maps to close on POSIX
* closesocket maps to a wrapper that calls the real closesocket()
on Windows
Replace the call to close a socket with closesocket() instead.

For using MSG_ZEROCOPY, there are two steps:
1 - io_writev() the packet, which enqueues the packet for sending, and
2 - io_flush(), which gets confirmation that all packets got correctly sent
Currently, if MSG_ZEROCOPY is used to send packets over IPV6, no error will
be reported in (1), but it will fail in the first time (2) happens.
This happens because (2) currently checks for cmsg_level & cmsg_type
associated with IPV4 only, before reporting any error.
Add checks for cmsg_level & cmsg_type associated with IPV6, and thus enable
support for MSG_ZEROCOPY + IPV6

Since QEMU's platform support policy is based on libvirt's, it
makes sense to mirror these recent changes made to the latter.
The policy is not altered significantly - we're simply spelling

This is not causing problems (as far as we're aware of) at this moment,

hw/ppc: sam460ex.c: store all GPIO lines in mal_irqs[]
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
We're not storing all GPIO lines we're retrieving with
qdev_get_gpio_in() in mal_irqs[]. We're storing just the last one in the
first index:
for (i = 0; i < ARRAY_SIZE(mal_irqs); i++) {
mal_irqs[0] = qdev_get_gpio_in(uic[2], 3 + i);
}
ppc4xx_mal_init(env, 4, 16, mal_irqs);
mal_irqs is used in ppc4xx_mal_init() to assign the IRQs to MAL:
for (i = 0; i < 4; i++) {
mal->irqs[i] = irqs[i];
}
Since only irqs[0] has been initialized, mal->irqs[1,2,3] are being
zeroed.
This doesn´t seem to trigger any apparent issues at this moment, but
Cedric's QOMification of the MAL device [1] is executing a
sysbus_connect_irq() that will fail if we do not store all GPIO lines
properly.

GCC has __builtin_mul_overflow since version 5 already, and Clang 6.0
also provides this built-in function (see its documentation on this page:
