7e6b5497ea hw/char: Extract serial-mm
hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.

The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:

  # grep -r -e "select SERIAL" | grep -v SERIAL_
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL
  hw/char/Kconfig:    select SERIAL

  # grep -r -e "/serial\\.h"
  include/hw/char/serial-mm.h:#include "hw/char/serial.h"
  hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
  hw/char/serial.c:#include "hw/char/serial.h"
  hw/char/serial-isa.c:#include "hw/char/serial.h"
  hw/char/serial-pci.c:#include "hw/char/serial.h"

37b724cdef hw/char/serial.h: Extract serial-isa.h
The includes where updated based on compile errors. Now, the inclusion of the
header roughly matches Kconfig dependencies:

  # grep -r -e "select SERIAL_ISA"

0701abbf98 target/i386: Expose IBPB-BRTYPE and SBPB CPUID bits to the guest
According to AMD's Speculative Return Stack Overflow whitepaper (link
below), the hypervisor should synthesize the value of IBPB_BRTYPE and
SBPB CPUID bits to the guest.

Support for this is already present in the kernel with commit
e47d86083c66 ("KVM: x86: Add SBPB support") and commit 6f0f23ef76be
("KVM: x86: Add IBPB_BRTYPE support").

Add support in QEMU to expose the bits to the guest OS.

804dfbe3ef kvm: replace fprintf with error_report()/printf() in kvm_init()
error_report() is more appropriate for error situations. Replace fprintf with
error_report() and error_printf() as appropriate. Some improvement in error
reporting also happens as a part of this change. For example:

From:
$ ./qemu-system-x86_64 --accel kvm
Could not access KVM kernel module: No such file or directory

To:
$ ./qemu-system-x86_64 --accel kvm
qemu-system-x86_64: --accel kvm: Could not access KVM kernel module: No such file or directory

87e82951c1 kvm/i386: fix return values of is_host_cpu_intel()
is_host_cpu_intel() should return TRUE if the host cpu in Intel based, otherwise
it should return FALSE. Currently, it returns zero (FALSE) when the host CPU
is INTEL and non-zero otherwise. Fix the function so that it agrees more with
the semantics. Adjust the calling logic accordingly. RAPL needs Intel host cpus.
If the host CPU is not Intel baseed, we should report error.

89d26d34ce tests/unit: remove block layer code from test-nested-aio-poll
GCC is reporting a NULL pointer dereference when compiling aio_wait_kick()
with LTO.

The issue is that test-nested-aio-poll.c does not call qemu_init_main_loop().
It doesn't _need_ to because it never calls AIO_WAIT_WHILE(), but it seems
that LTO does not do enough dead-code elimination to catch that.

Fortunately aio_wait_kick() is only used in few places, and only in block
layer or system emulation code; and this test only needs the core event loop
functionality.  It does not even need iothreads.   So remove everything that
calls aio_wait_kick(), which is nice for coverage compared to adding the call
to qemu_init_main_loop().

Adds support for the controller atomic parameters: AWUN and AWUPF. Atomic
Compare and Write Unit (ACWU) is not currently supported.

Writes that adhere to the ACWU and AWUPF parameters are guaranteed to be atomic.

New NVMe QEMU Parameters (See NVMe Specification for details):
       atomic.dn (default off) - Set the value of Disable Normal.
       atomic.awun=UINT16 (default: 0)
       atomic.awupf=UINT16 (default: 0)

By default (Disable Normal set to zero), the maximum atomic write size is
set to the AWUN value.  If Disable Normal is set, the maximum atomic write
size is set to AWUPF.

6475155d51 block/reqlist: allow adding overlapping requests
Allow overlapping request by removing the assert that made it
impossible. There are only two callers:

1. block_copy_task_create()

It already asserts the very same condition before calling
reqlist_init_req().

2. cbw_snapshot_read_lock()

There is no need to have read requests be non-overlapping in
copy-before-write when used for snapshot-access. In fact, there was no
protection against two callers of cbw_snapshot_read_lock() calling
reqlist_init_req() with overlapping ranges and this could lead to an
assertion failure [1].

In particular, with the reproducer script below [0], two
cbw_co_snapshot_block_status() callers could race, with the second
calling reqlist_init_req() before the first one finishes and removes
its conflicting request.

6252deb244 backup: add minimum cluster size to performance options
In the context of backup fleecing, discarding the source will not work
when the fleecing image has a larger granularity than the one used for
block-copy operations (can happen if the backup target has smaller
cluster size), because cbw_co_pdiscard_snapshot() will align down the
discard requests and thus effectively ignore then.

To make @discard-source work in such a scenario, allow specifying the
minimum cluster size used for block-copy operations and thus in
particular also the granularity for discard requests to the source.

9484ad6c17 copy-before-write: allow specifying minimum cluster size
In the context of backup fleecing, discarding the source will not work
when the fleecing image has a larger granularity than the one used for
block-copy operations (can happen if the backup target has smaller
cluster size), because cbw_co_pdiscard_snapshot() will align down the

To make @discard-source work in such a scenario, allow specifying the
minimum cluster size used for block-copy operations and thus in
particular also the granularity for discard requests to the source.

The type 'size' (corresponding to uint64_t in C) is used in QAPI to
rule out negative inputs and for consistency with already existing
@cluster-size parameters. Since block_copy_calculate_cluster_size()
uses int64_t for its result, a check that the input is not too large
is added in block_copy_state_new() before calling it. The calculation
in block_copy_calculate_cluster_size() is done in the target int64_t
type.

dc05b2628e .gitlab-ci.d: Make separate collapsible log sections for build and test
GitLab lets a CI job create its own collapsible log sections by
emitting special escape codes, as documented here:

https://docs.gitlab.com/ee/ci/yaml/script.html#expand-and-collapse-job-log-sections

Use these to make "configure", "build" and "test" separate
collapsible stages.

As recommended by the GitLab docs, we use some shell which is
sourced in the CI job to define functions to emit the magic
lines that start and end sections, to hide the ugliness of
the printf lines from the log.

1cde10ef01 .gitlab-ci.d: Split build and test in cross build job templates
In the native_build_job_template we have separate steps in the script
for the build and the test steps.  This is helpful because then
gitlab will give separate timestamps in the log view for each, and
you can see how long it took to compile vs how long to test.  In the
templates in crossbuild-template.yml, however, we do both the build
and test in a single 'make' invocation, and so we don't get the
separate timing information.

Split the build and test, in the same way we do in the native build
template.

This will also give us a place to separate out how parallel we want
to do the build by default from how parallel we want to do the tests
by default, which might be helpful in future.
