After cache models have topology information, we can use
CPUCacheInfo.share_level to decide which topology level to be encoded
into CPUID[0x801D].EAX[bits 25:14].

The property x-l2-cache-topo will be used to change the L2 cache
topology in CPUID.04H.
Now it allows user to set the L2 cache is shared in core level or
cluster level.
If user passes "-cpu x-l2-cache-topo=[core|cluster]" then older L2 cache
topology will be overrided by the new

In cpu_x86_cpuid(), there are many variables in representing the cpu
topology, e.g., topo_info, cs->nr_cores/cs->nr_threads.
Since the names of cs->nr_cores/cs->nr_threads does not accurately
represent its meaning, the use of cs->nr_cores/cs->nr_threads is prone
to confusion and

For i-cache and d-cache, the maximum IDs for CPUs sharing cache (
CPUID.04H.00H:EAX[bits 25:14] and CPUID.04H.01H:EAX[bits 25:14]) are
both 0, and this means i-cache and d-cache are shared in the SMT level.
This is correct if there's single thread per core, but is wrong for the

Hi list,
This is the our v2 patch series, rebased on the master branch at the
commit ac84b57b4d74 ("Merge tag 'for-upstream' of
https://gitlab.com/bonzini/qemu into staging").
Comparing with v1 [1], v2 mainly reorganizes patches and does some
cleanup.

when returning to lower-privilege mode by MRET/SRET).

This patchset tries to fix some problems in the fields of mstatus, such as make

Hey,
This tiny series changes the tracepoint to include the number of
dirty pages via the vfio_get_dirty_bitmap. I find it useful for
observability in general to understand the number of dirty pages in an
IOVA range. With dirty tracking supported by device or IOMMU it's specially
relevant data to
Include the number of dirty pages on the vfio_get_dirty_bitmap tracepoint.
These are fetched from the newly added return value in

We keep track of translations but can only do so up until the
translation cache is flushed. At that point we really have no idea if
we can re-create a translation because all the active tracking
information has been reset.

To store statistics for each TB, we created a TBStatistics structure
which is linked with the TBs. TBStatistics can stay alive after
tb_flush and be relinked to a regenerated TB. So the statistics can
be accumulated even through flushes.
The goal is to have all

Dump the hottest TBs if -d tb_stats,dump_limit=N is used.
Example of output for the 3 hottest TBs:

-d tb_stats[[,level=(+all+jit+exec+time)][,dump_limit=]]
"dump_limit" is used to limit the number of dumped TBStats in
linux-user mode.
[all+jit+exec+time] control the profilling level used
by the TBStats. Can be used as follow:

Adding tb_stats [start|pause|stop|filter] command to hmp.
This allows controlling the collection of statistics.
It is also possible to set the level of collection:
all, jit, or exec.
tb_stats filter allow to only collect statistics for the TB

TBStats will be introduced to replace CONFIG_PROFILER totally, here
remove all CONFIG_PROFILER related stuffs first.
