Hi,
Valgrind is not happy with how we're using KVM functions that receives a

complaints about uninitialized values when using these functions
because, as default, Valgrind doesn't know that the variable is being
initialized in the fu

When rebuilding the refcount structures (when qemu-img check -r found
errors with refcount = 0, but reference count > 0), the new refcount
table defaults to being put at the image file end[1]. There is no good

Instead of fprint()-ing error messages in rebuild_refcount_structure()

There are still some files in the QEMU PPC code base that use TABs for
indentation instead of using spaces.
The TABs should be replaced so that we have a consistent coding style.
If this patch is applied, issue:

v2:
- Add BDRV_REQ_REGISTERED_BUF to bs.supported_write_flags [Stefano]
- Use new blkioq_get_num_completions() API
- Implement .bdrv_refresh_limits()
This patch series adds a QEMU BlockDriver for libblkio
(https://gitlab.com/libblkio/libblkio/), a library for high-performance block
device I/O. Cur
The only implementor of bdrv_register_buf() is block/nvme.c, where the
size is not needed when unregistering a buffer. This is because
util/vfio-helpers.c can look up mappings by address.
Future block drivers that implement bdrv_register_buf() may not be able
to do their job given only the buffer
libblkio (https://gitlab.com/libblkio/libblkio/) is a library for
high-performance disk I/O. It currently supports io_uring with
additional drivers planned.
One of the reasons for developing libblkio is that other applications
besides QEMU can use it. This will be particularly useful for
vhost-use
Block drivers may optimize I/O requests accessing buffers previously
registered with bdrv_register_buf(). Checking whether all elements of a
request's QEMUIOVector are within previously registered buffers is
expensive, so we need a hint from the user to avoid costly checks.
Add a BDRV_REQ_REGISTER
The blkio block driver will need to look up the file descriptor for a
given pointer. This is possible in softmmu builds where the memory API
is available for querying guest RAM.
Add stubs so tools like qemu-img that link the block layer still build
successfully. In this case there is no guest RAM
When a RAMBlockNotifier is added, ->ram_block_added() is called with all
existing RAMBlocks. There is no equivalent ->ram_block_removed() call
when a RAMBlockNotifier is removed.
The util/vfio-helpers.c code (the sole user of RAMBlockNotifier) is fine
with this asymmetry because it does not rely o
Emulated devices and other BlockBackend users wishing to take advantage
of blk_register_buf() all have the same repetitive job: register
RAMBlocks with the BlockBackend using RAMBlockNotifier.
Add a BlockRAMRegistrar API to do this. A later commit will use this
from hw/block/virtio-blk.c.
Signed-
Register guest RAM using BlockRAMRegistrar and set the
BDRV_REQ_REGISTERED_BUF flag so block drivers can optimize memory
accesses in I/O requests.
This is for vdpa-blk, vhost-user-blk, and other I/O interfaces that rely
on DMA mapping/unmapping.

Avoid bounce buffers when QEMUIOVector elements are within previously
registered bdrv_register_buf() buffers.
The idea is that emulated storage controllers will register guest RAM
using bdrv_register_buf() and set the BDRV_REQ_REGISTERED_BUF on I/O
requests. Therefore no blkio_add_mem_region() cal

Recommendation for comment?
/* vri-d encoding matches vrr for 4b imm.
.insn does not handle this encoding variant.
*/
Christian: I will push another patch version as soon as that's decided.
