When using JSON syntax for -device, -set option can not find device
specified in JSON by id field. The following commandline is an example:
$ qemu-system-x86_64 -device '{"id":"foo"}' -set device.foo.bar=1
qemu-system-x86_64: -set device.foo.bar=1: there is no device "foo" defined

Just curious: uint_8 can always correctly converted to a int, so the patch

The enablement of postcopy listening has a few steps, add a few tracepoints to
be there ready for some basic measurements for them.

This function calls three functions:
- postcopy_discard_send_init(ms, block->idstr);
- postcopy_chunk_hostpages_pass(ms, block);
- postcopy_discard_send_finish(ms);
However only the 2nd function call is meaningful. It's major role is to make
sure dirty bits are applied in host-page-size
Right now we loop ramblocks for twice, the 1st time chunk the dirty bits with
huge page information; the 2nd time we send the discard ranges. That's not
necessary - we can do them in a single loop.

This patch is to improve the logic of QEMU main thread sleep code in
qemu_chr_write_buffer() where it can be blocked and can't run other
coroutines during COLO IO stress test.
Our approach is to put filter_send() in a coroutine. In this way,
filter_send() will call qemu_coroutine_yield() in
Because sa may be 0,
tcg_gen_deposit_reg(dest, t0, cpu_gr[a->r1], 32 - sa, sa);
may attempt a zero-width deposit at bit 32, which will assert
for TARGET_REGISTER_BITS == 32.
Use the newer extract2 when possible, which itself includes the
rotri special case; otherwise mirror the code from

Hi,
In this version the tedious repetition was taken away from the
code by using a helper that increments the PMCs based on specified
conditions.
As far as Avocado test goes, the performance is the same as the previous
version. All PMU-EBB kernel selftests are also passing. Basically we have
the
pmu_check_overflow() will verify for overflow in the PMC1-5 counters,
firing a performance monitor alert if an overflow happened with the
proper MMCR0 bits set.
The alert is fired by using helper_pmu_overflow().

inc_spr_if_cond() will help deal with this repetition. This patch also

supposed to be
Use inc_spr_if_cond() to count instructions of all other PMCs that are
capable of counting instructions (all PMCs but PMC6).

We're going to add a significant amount of TCG ops code for
instruction counting, eventually getting rid of the 'helper_insn_inc'
helper entirely.
Create a new file to avoid putting even more stuff on the already
crowded target/ppc/translate.c.

This won't work. The hva_tree relies on there being exactly one virtual

Hmm, relying on flush requests sequence doesn't seem reliable..
Maybe, it's better to insert blockdev-add filter after JOB_READY? blockdev-reopen should

Using a physical pc requires to translate address every time next block

Don't do the double-underscore thing.
It's technically a reserved namespace.
Use e.g. ppc_radix_xlate_impl.

We are going to add filtering in _qcow2_dump_header and want all tests
use it.
The patch is generated by commands:
cd tests/qemu-iotests
sed -ie 's/$PYTHON qcow2.py "$TEST_IMG" dump-header\($\|
\)/_qcow2_dump_header\1/' ??? tests/*
(the difficulty is to avoid converting dump-header-exts)
_qcow2_dump_header has filter for compression type, so this change
makes test pass with IMGOPTS='compression_type=zstd'.

We want iotests pass with both the default zlib compression and with
IMGOPTS='compression_type=zstd'.
Actually the only test that is interested in real compression type in
test output is 287 (test for qcow2 compression type), so implement
specific option for it.

We'll use it in tests instead of explicit qcow2.py. Then we are going
to add some filtering in _qcow2_dump_header.
