Since qemu 8.2, the combination of NBD + TLS + iothread crashes on an
assertion failure:
qemu-kvm: ../io/channel.c:534: void qio_channel_restart_read(void *): Assertion `qemu_get_current_aio_context() == qemu_coroutine_get_aio_context(co)' failed.
It turns out that when we removed AioContext locking, we did so by
having NBD tell its qio channels that it wanted to opt in to
qio_channel_set_follow_coroutine_ctx(); but while we opted in on the
main channel, we did not opt in on the TLS wrapper channel.
qemu-iotests has coverage of NBD+iothread and NBD+TLS, but apparently
no coverage of NBD+TLS+iothread, or we would have noticed this
regression sooner. (I'll add that in the next patch)
But while we could manually opt in to the TLS channel in nbd/server.c
(a one-line change), it is more generic if all qio channels that wrap
other channels inherit the follow status, in the same way that they
inherit feature bits.

In gic_cpu_read() and gic_cpu_write(), we delegate the handling of
reading and writing the Non-Secure view of the GICC_APR<n> registers
to functions gic_apr_ns_view() and gic_apr_write_ns_view().
Unfortunately we got the order of the arguments wrong, swapping the
CPU number and the register number (which the compiler doesn't catch
because they're both integers).
Most guests probably didn't notice this bug because directly
accessing the APR registers is typically something only done by
firmware when it is doing state save for going into a sleep mode.
Correct the mismatched call arguments.
Found by Linux Verification Center (linuxtesting.org) with SVACE.

We wrongly encoded ID_AA64PFR1_EL1 using {3,0,0,4,2} in hvf_sreg_match[] so
we fail to get the expected ARMCPRegInfo from cp_regs hash table with the
wrong key.
Fix it with the correct encoding {3,0,0,4,1}. With that fixed, the Linux
guest can properly detect FEAT_SSBS2 on my M1 HW.
All DBG{B,W}{V,C}R_EL1 registers are also wrongly encoded with op0 == 14.
It happens to work because HVF_SYSREG(CRn, CRm, 14, op1, op2) equals to
HVF_SYSREG(CRn, CRm, 2, op1, op2), by definition. But we shouldn't rely on
it.

The TSAN job started failing when gitlab rolled out their latest
release. The root cause is a change in the Google COS version used
on shared runners. This brings a kernel running with
vm.mmap_rnd_bits = 31
which is incompatible with TSAN in LLVM < 18, which only supports
upto '28'. LLVM 18 can support upto '30', and failing that will
re-exec itself to turn off VA randomization.
Our LLVM is too old for now, but we can run with 'setarch -R make ..'
to turn off VA randomization ourselves.

This bug fix addresses the incorrect return value of kvm_hv_handle_exit for
KVM_EXIT_HYPERV_SYNIC, which should be EXCP_INTERRUPT.
Handling of KVM_EXIT_HYPERV_SYNIC in QEMU needs to be synchronous.
This means that async_synic_update should run in the current QEMU vCPU
thread before returning to KVM, returning EXCP_INTERRUPT to guarantee this.
Returning 0 can cause async_synic_update to run asynchronously.
One problem (kvm-unit-tests's hyperv_synic test fails with timeout error)
caused by this bug:
When a guest VM writes to the HV_X64_MSR_SCONTROL MSR to enable Hyper-V SynIC,
a VM exit is triggered and processed by the kvm_hv_handle_exit function of the
QEMU vCPU. This function then calls the async_synic_update function to set
synic->sctl_enabled to true. A true value of synic->sctl_enabled is required
before creating SINT routes using the hyperv_sint_route_new() function.
If kvm_hv_handle_exit returns 0 for KVM_EXIT_HYPERV_SYNIC, the current QEMU
vCPU thread may return to KVM and enter the guest VM before running
async_synic_update. In such case, the hyperv_synic test’s subsequent call to
synic_ctl(HV_TEST_DEV_SINT_ROUTE_CREATE, ...) immediately after writing to
HV_X64_MSR_SCONTROL can cause QEMU’s hyperv_sint_route_new() function to return
prematurely (because synic->sctl_enabled is false).
If the SINT route is not created successfully, the SINT interrupt will not be
fired, resulting in a timeout error in the hyperv_synic test.

Remove gtk_widget_get_scale_factor() usage from the calculation of
the motion events in the GTK backend to make it work correctly on
environments that have `gtk_widget_get_scale_factor() != 1`.
This scale factor usage had been introduced in the commit f14aab420c and
at that time the window size was used for calculating the things and it
was working correctly. However, in the commit 2f31663ed4 the logic
switched to use the widget size instead of window size and because of
the change the usage of scale factor becomes invalid (since widgets use
`vc->gfx.scale_{x, y}` for scaling).
Tested on Crostini on ChromeOS (15823.51.0) with an external display.

If you try to run the configure script on a system without a working

ERROR: Unrecognized host OS (uname -s reports 'Linux')
Some people already opened bug tickets because of this problem:
https://gitlab.com/qemu-project/qemu/-/issues/2057
https://gitlab.com/qemu-project/qemu/-/issues/2288
We should rather tell the user that we were not able to use the C
compiler instead, otherwise they will have a hard time to figure
out what was going wrong.
While we're at it, let's also suppress the "unrecognized host CPU"
message in this case since it is rather misleading than helpful.

Ensure that they go through unmodified, instead of removing one layer
of quoting.
-D is a pretty specialized option and most options that can have spaces
do not need it (for example, c_args is covered by --extra-cflags).
Therefore it's unlikely that this causes actual trouble. However,
a somewhat realistic failure case would be with -Dpkg_config_path
and a pkg-config directory that contains spaces.

According to the manual, 32-bit vs 64-bit is governed by REX.W
and REX ignores the 0x66 prefix. This can be confirmed with this
program:
#include <stdio.h>
int main()
{
int x = 0x12340000;
int y;
asm("popcntl %1, %0" : "=r" (y) : "r" (x)); printf("%x\n", y);
asm("mov $-1, %0; .byte 0x66; popcntl %1, %0" : "+r" (y) : "r" (x)); printf("%x\n", y);
asm("mov $-1, %0; .byte 0x66; popcntq %q1, %q0" : "+r" (y) : "r" (x)); printf("%x\n", y);
}
which prints 5/ffff0000/5 on real hardware and 5/ffff0000/ffff0000
on QEMU.

When emulated with QEMU, interrupts will never come in the following
loop. However, if the NOP instruction is uncommented, interrupts will
fire as normal.
loop:
cli
call do_sti
jmp loop
do_sti:
sti
# nop
ret
This behavior is different from that of a real processor. For example,
if KVM is enabled, interrupts will always fire regardless of whether the
NOP instruction is commented or not. Also, the Intel Software Developer
Manual states that after the STI instruction is executed, the interrupt
inhibit should end as soon as the next instruction (e.g., the RET
instruction if the NOP instruction is commented) is executed.
This problem is caused because the previous code may choose not to end
the TB even if the HF_INHIBIT_IRQ_MASK has just been reset (e.g., in the
case where the STI instruction is immediately followed by the RET
instruction), so that IRQs may not have a change to trigger. This commit
fixes the problem by always terminating the current TB to give IRQs a
chance to trigger when HF_INHIBIT_IRQ_MASK is reset.

The documentation says:
SUBV Rm, Rn Rn - Rm -> Rn, underflow -> T
The overflow / underflow can be calculated as:
T = ((Rn ^ Rm) & (Result ^ Rn)) >> 31
However we were using the incorrect:
T = ((Rn ^ Rm) & (Result ^ Rm)) >> 31
Fix by using the Rn register instead of Rm.

The DMA descriptor structures for this device have
a set of "address extension" fields which extend the 32
bit source addresses with an extra 16 bits to give a
48 bit address:
https://docs.amd.com/r/en-US/ug1085-zynq-ultrascale-trm/ADDR_EXT-Field
However, we misimplemented this address extension in several ways:
* we only extracted 12 bits of the extension fields, not 16
* we didn't shift the extension field up far enough
* we accidentally did the shift as 32-bit arithmetic, which
meant that we would have an overflow instead of setting
bits [47:32] of the resulting 64-bit address
Add a type cast and use extract64() instead of extract32()
to avoid integer overflow on addition. Fix bit fields
extraction according to documentation.

Cirrus-CI introduced limitations to the free CI minutes. To avoid that
we are consuming them too fast, let's drop the usual targets that are
not that important since they are either a subset of another target
(like i386 or ppc being a subset of x86_64 or ppc64 respectively), or
since there is still a similar target with the opposite endianness
(like xtensa/xtensael, microblaze/microblazeel etc.).

nbd_negotiate() is already marked coroutine_fn. And given the fix in
the previous patch to have nbd_negotiate_handle_starttls not create

Coroutines are not supposed to block. Instead, they should yield.
The client performs TLS upgrade outside of an AIOContext, during
synchronous handshake; this still requires g_main_loop. But the
server responds to TLS upgrade inside a coroutine, so a nested
g_main_loop is wrong. Since the two callbacks no longer share more
than the setting of data.complete and data.error, it's just as easy to
use static helpers instead of trying to share a common code path. It
is also possible to add assertions that no other code is interfering
with the eventual path to qio reaching the callback, whether or not it
required a yield or main loop.

During the booting process of the non-standard image, the behavior of the
called function in qemu is as follows:
1. vhost_net_stop() was triggered by guest image. This will call the function
virtio_pci_set_guest_notifiers() with assgin= false,
virtio_pci_set_guest_notifiers(） will release the irqfd for vector 0
2. virtio_reset() was triggered, this will set configure vector to VIRTIO_NO_VECTOR
3.vhost_net_start() was called (at this time, the configure vector is
still VIRTIO_NO_VECTOR) and then call virtio_pci_set_guest_notifiers() with
assgin=true, so the irqfd for vector 0 is still not "init" during this process
4. The system continues to boot and sets the vector back to 0. After that
msix_fire_vector_notifier() was triggered to unmask the vector 0 and meet the crash
To fix the issue, we need to support changing the vector after VIRTIO_CONFIG_S_DRIVER_OK is set.
