The 'check' script will use "#!/usr/bin/env python3" by default
to locate python, but this doesn't work in distros which lack a
bare 'python3' binary like NetBSD.
We need to explicitly invoke 'check' by referring to the 'python'
variable in meson, which resolves to the detected python binary
that QEMU intends to use.
This fixes a regression introduced by

This is a very rough and ready first pass at comparing gcovr's json
output between two different runs. At the moment it will give you a
file level diff between two runs but hopefully it wont be too hard to
extend to give better insight.
After generating the coverage results you run with something like:
./scripts/coverage/compare_gcov_json.py \
-a ./builds/gcov.config1/coverage.json \
-b ./builds/gcov.config2/coverage.json
My hope is we can use this to remove some redundancy from testing as
well as evaluate if new tests are actually providing additional
coverage or just burning our precious CI time.

Nagle's algorithm adds latency in order to reduce network packet
overhead on small packets. But when we are already using corking to
merge smaller packets into transactional requests, the extra delay
from TCP defaults just gets in the way (see recent commit bd2cd4a4).
For reference, qemu as an NBD client already requests TCP_NODELAY (see
nbd_connect() in nbd/client-connection.c); as does libnbd as a client
[1], and nbdkit as a server [2]. Furthermore, the NBD spec recommends
the use of TCP_NODELAY [3].

The problem is that the Linux driver expects the master transaction inhibit
bit(R_SPICR_MTI) to be set during driver initialization so that it can
detect the fifo size but QEMU defaults it to zero out of reset. The
datasheet indicates this bit is active on reset.

In commit 049edada we added some code to handle HSTR_EL2 traps, which
we did as an inline "conditionally branch over a
gen_exception_insn()". Unfortunately this fails to take account of
the fact that gen_exception_insn() will set s->base.is_jmp to
DISAS_NORETURN. That means that at the end of the TB we won't
generate the necessary code to handle the "branched over the trap and
continued normal execution" codepath. The result is that the TCG
main loop thinks that we stopped execution of the TB due to a
situation that only happens when icount is enabled, and hits an
assertion. Explicitly set is_jmp back to DISAS_NEXT so we generate
the correct code for when execution continues past this insn.
Note that this only happens for cpreg reads; writes will call
gen_lookup_tb() which generates a valid end-of-TB.

At this moment, arm_load_dtb() can free machine->fdt when
binfo->dtb_filename is NULL. If there's no 'dtb_filename', 'fdt' will be
retrieved by binfo->get_dtb(). If get_dtb() returns machine->fdt, as is
the case of machvirt_dtb() from hw/arm/virt.c, fdt now has a pointer to
machine->fdt. And, in that case, the existing g_free(fdt) at the end of
arm_load_dtb() will make machine->fdt point to an invalid memory region.
Since monitor command 'dumpdtb' was introduced a couple of releases
ago, running it with any ARM machine that uses arm_load_dtb() will
crash QEMU.
Let's enable all arm_load_dtb() callers to use dumpdtb properly. Instead
of freeing 'fdt', assign it back to ms->fdt.

aarch64_gdb_get_pauth_reg() -- although disabled since commit
5787d17a42 ("target/arm: Don't advertise aarch64-pauth.xml to

located in target/arm/tcg/pauth_helper.c, a TCG specific helper.
To avoid a linking error when TCG is not enabled:

145e2198d749 ("hw/mips/gt64xxx_pci: Endian-swap using PCI_HOST_BRIDGE
MemoryRegionOps") converted CFGADDR/CFGDATA registers to use
PCI_HOST_BRIDGE's accessor facility and enabled byte swap for both
CFGADDR/CFGDATA register.
However CFGADDR as a ISD internal register is not controlled by
MByteSwap bit, it follows endian of all other ISD register, which
means it ties to little endian.
Move mapping of CFGADDR out of gt64120_update_pci_cfgdata_mapping
to disable endian-swapping.

Per the release 6.06 revision history:
5.03 August 21, 2013
• ABS2008 and NAN2008 fields of Table 5.7 “FCSR RegisterField
Descriptions” were optional in release 3 and could be R/W,
but as of release 5 are required, read-only, and preset by
hardware.
The P5600 core implements the release 5, and has the ABS2008
and NAN2008 bits set in CP1_fcr31. Therefore it is able to run
ELF binaries compiled with EF_MIPS_NAN2008, such the CIP United
Debian NaN2008 distribution:
http://repo.oss.cipunited.com/mipsel-nan2008/README.txt
In order to run such compiled binaries, select by default the
P5600 core when the ELF 'MIPS_NAN2008' flag is set.

CPU watchpoints can be use by non-TCG accelerators.
KVM uses them:
$ git grep CPUWatchpoint|fgrep kvm
target/arm/kvm64.c:1558: CPUWatchpoint *wp = find_hw_watchpoint(cs, debug_exit->far);
target/i386/kvm/kvm.c:5216:static CPUWatchpoint hw_watchpoint;
target/ppc/kvm.c:443:static CPUWatchpoint hw_watchpoint;
target/s390x/kvm/kvm.c:139:static CPUWatchpoint hw_watchpoint;
See for example commit e4482ab7e3 ("target-arm: kvm - add support
for HW assisted debug"):
This adds basic support for HW assisted debug. The ioctl interface
to KVM allows us to pass an implementation defined number of break
and watch point registers. [...]
This partially reverts commit 2609ec2868e6c286e755a73b4504714a0296a.

cpu_watchpoint_insert() calls error_report() which is declared
in "qemu/error-report.h". When moving this code in commit 2609ec2868
("softmmu: Extract watchpoint API from physmem.c") we neglected to
include this header. This works so far because it is indirectly
included by TCG headers -> "qemu/plugin.h" -> "qemu/error-report.h".
Currently cpu_watchpoint_insert() is only built with the TCG
accelerator. When building it with other ones (or without TCG)
we get:
softmmu/watchpoint.c:38:9: error: implicit declaration of function 'error_report' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
error_report("tried to set invalid watchpoint at %"
^
Include "qemu/error-report.h" in order to fix this for non-TCG
builds.

qemu-user can hang in a multi-threaded fork. One common
reason is that when creating a TB, between fork and exec
we manipulate a GTree whose memory allocator (GSlice) is
not fork-safe.
Although POSIX does not mandate it, the system's allocator
(e.g. tcmalloc, libc malloc) is probably fork-safe.
Fix some of these hangs by using QTree, which uses the system's
allocator regardless of the Glib version that we used at
configuration time.
Tested with the test program in the original bug report, i.e.:
```
void garble() {
int pid = fork();
if (pid == 0) {
exit(0);
} else {
int wstatus;
waitpid(pid, &wstatus, 0);
}
}
void supragarble(unsigned depth) {
if (depth == 0)
return ;
std::thread a(supragarble, depth-1);
std::thread b(supragarble, depth-1);
garble();
a.join();
b.join();
}
int main() {
supragarble(10);
}
```

The only reason to add this implementation is to control the memory allocator
used. Some users (e.g. TCG) cannot work reliably in multi-threaded
environments (e.g. forking in user-mode) with GTree's allocator, GSlice.
See https://gitlab.com/qemu-project/qemu/-/issues/285 for details.
Importing GTree is a temporary workaround until GTree migrates away
from GSlice.
This implementation is identical to that in glib v2.75.0, except that
we don't import recent additions to the API nor deprecated API calls,
none of which are used in QEMU.
I've imported tests from glib and added a benchmark just to
make sure that performance is similar. Note: it cannot be identical
because (1) we are not using GSlice, (2) we use different compilation flags
(e.g. -fPIC) and (3) we're linking statically.

Cortex-M profile is only emulable from TCG accelerator. Restrict
the GDBstub features to its availability in order to avoid a link
error when TCG is not enabled:
Undefined symbols for architecture arm64:
"_arm_v7m_get_sp_ptr", referenced from:
_m_sysreg_get in target_arm_gdbstub.c.o
"_arm_v7m_mrs_control", referenced from:
_arm_gdb_get_m_systemreg in target_arm_gdbstub.c.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Add support for stripping/inserting VLAN for VFs.
Had to move CSUM calculation back into the for loop, since packet data
is pulled inside the loop based on strip VLAN decision for every VF.
net_rx_pkt_fix_l4_csum should be extended to accept a buffer instead for
igb. Work for a future patch.
