Hi Kevin & Juan,
I found the function bdrv_invalidate_cache_all() in the

with shared storage, which prolong the service down time.

Hi,
sometimes the make fails when one switches between commits without running
"make clean".
This is caused by loading old *.d dependency info files and is harmful for
autogenerated sources with their own includes. This situation may
significantly slow down the process of git bisect.
These two
In rules like "bar/%.o: %.c" there is a difference between $(*D) and
$(@D). It is cleaner to generate *.d next to appropriate *.o, because it
allows precise including of dependency info from .d files.
As a hack, we also touch two sources for generated *.hex files. This is
to ensure *.hex rebuild,
This (partially) divorces counting instructions from basic block
collection so instructions can be counted without the bbv plugin being
enabled.

This patch adds some test cases for the memory limit concerning the
in-memory structures used to detect and prevent accidental metadata
overlaps.

This adds logic to increment PMEVCNTR's based on different event inputs,
implements all remaining CP registers, and triggers an interrupt on

The icount setting specifies how far to shift the instruction
count as a ratio of ns to tie system time to instruction count.
Allow a negative value (i.e. a right shift instead of a left shift)
to be used.

Later, a mechanism to set a limit on how much memory may be used for the
overlap prevention structures will be introduced. If that limit is about
to be exceeded, a QMP event should be emitted. This very event is
specified by this patch.

It is not qemu that hangs.
The u-boot.e500 software falls into an eternal loop at the addresses 0x00f1f964
to 0x00f1f94c
due to the registers r9 and r10 (both) being 0x0 in the newer versions and 0x40
in the working 2.2.1 version.
Howerver, those values ought to have originated from the qemu

The existing qcow2 metadata overlap detection function used existing
structures to determine the location of the image metadata, from plain
fields such as l1_table_offset and l1_size in the BDRVQcowState, over
image structures in memory such as the L1 table for the L2 tables'
positions, or it even
