36d83272d5 hw/nvme: do not auto-generate eui64
We cannot provide auto-generated unique or persistent namespace
identifiers (EUI64, NGUID, UUID) easily. Since 6.1, namespaces have been
assigned a generated EUI64 of the form "52:54:00:<namespace counter>".
This is will be unique within a QEMU instance, but not globally.

Revert that this is assigned automatically and immediately deprecate the
compatibility parameter. Users can opt-in to this with the
`eui64-default=on` device parameter or set it explicitly with
`eui64=UINT64`.

a859eb9f8f hw/nvme: enforce common serial per subsystem
The Identify Controller Serial Number (SN) is the serial number for the
NVM subsystem and must be the same across all controller in the NVM
subsystem.

Enforce this.

9235a72a5d hw/nvme: fix smart aen
Pass the right constant to nvme_smart_event(). The NVME_AER* values hold
the bit position in the SMART byte, not the shifted value that we expect
it to be in nvme_smart_event().

2e8f952ae7 hw/nvme: fix copy cmd for pi enabled namespaces
Current implementation have problem in the read part of copy command.
Because there is no metadata mangling before nvme_dif_check invocation,
reftag error could be thrown for blocks of namespace that have not been
previously written to.

51c4532663 hw/nvme: add missing return statement
Since there is no return after nvme_dsm_cb invocation, metadata
associated with non-zero block range is currently zeroed. Also this
behaviour leads to segfault since we schedule iocb->bh two times.
First when entering nvme_dsm_cb with iocb->idx == iocb->nr and
second because of missing return on call stack unwinding by calling
blk_aio_pwrite_zeroes and subsequent nvme_dsm_cb callback.

1e64facc01 hw/nvme: fix narrowing conversion
Since nlbas is of type int, it does not work with large namespace size
values, e.g., 9 TB size of file backing namespace and 8 byte metadata
with 4096 bytes lbasz gives negative nlbas value, which is later
promoted to negative int64_t type value and results in negative
ns->moff which breaks namespace

707d93d4ab ui: Remove deprecated options "-sdl" and "-curses"
We have "-sdl" and "-curses", but no "-gtk" and no "-cocoa" ...
these old-style options are rather confusing than helpful nowadays.
Now that the deprecation period is over, let's remove them, so we
get a cleaner interface (where "-display" is the only way to select
the user interface).

9eafdeeac3 ui: Switch "-display sdl" to use the QAPI parser
The "-display sdl" option still uses a hand-crafted parser for its
parameters since we didn't want to drag an interface we considered
somewhat flawed into the QAPI schema. Since the flaws are gone now,
it's time to QAPIfy.

This introduces the new "DisplaySDL" QAPI struct that is used to hold
the parameters that are unique to the SDL display. The only specific
parameter is currently "grab-mod" that is used to specify the required
modifier keys to escape from the mouse grabbing mode.

54354861d2 target/s390x: kvm: Honor storage keys during emulation
Storage key controlled protection is currently not honored when
emulating instructions.
If available, enable key protection for the MEM_OP ioctl, thereby
enabling it for the s390_cpu_virt_mem_* functions, when using kvm.
As a result, the emulation of the following instructions honors storage
keys:

* CLP
  	The Synch I/O CLP command would need special handling in order
  	to support storage keys, but is currently not supported.
* CHSC
	Performing commands asynchronously would require special
	handling, but commands are currently always synchronous.
* STSI
* TSCH
	Must (and does) not change channel if terminated due to
	protection.
* MSCH
	Suppressed on protection, works because fetching instruction.
* SSCH
	Suppressed on protection, works because fetching instruction.
* STSCH
* STCRW
	Suppressed on protection, this works because no partial store is
	possible, because the operand cannot span multiple pages.
* PCISTB
* MPCIFC
* STPCIFC

ec8c293678 hw/s390x/s390-virtio-ccw: Improve the machine description string
The machine name already contains the words "ccw" and "virtio", so
using "VirtIO-ccw" in the description likely does not really help
the average user to get an idea what this machine type is about.
Thus let's switch to "Virtual s390x machine" now, since "virtual
machine" should be a familiar term, and "s390x" signals that this
is about 64-bit guests (unlike S390 which could mean that it is
31-bit only).
Also expand "v" to "version", since this makes it easier to use
this macro also with non-numeric machine names in downstream.

28357dc525 gitlab: don't run CI jobs in forks by default
To preserve CI shared runner credits we don't want to run
pipelines on every push.

This sets up the config so that pipelines are never created
for contributors by default. To override this the QEMU_CI
variable can be set to a non-zero value. If set to 1, the
pipeline will be created but all jobs will remain manually
started. The contributor can selectively run jobs that they
care about. If set to 2, the pipeline will be created and
all jobs will immediately start.

This behavior can be controlled using push variables

  git push -o ci.variable=QEMU_CI=1

To make this more convenient define an alias

   git config --local alias.push-ci "push -o ci.variable=QEMU_CI=1"
   git config --local alias.push-ci-now "push -o ci.variable=QEMU_CI=2"

Which lets you run

  git push-ci

to create the pipeline, or

  git push-ci-now

to create and run the pipeline

e312d1fdbb gitlab: convert build/container jobs to .base_job_template
This converts the main build and container jobs to use the
base job rules, defining the following new variables

 - QEMU_JOB_SKIPPED - jobs that are known to be currently
   broken and should not be run. Can still be manually
   launched if desired.

 - QEMU_JOB_AVOCADO - jobs that run the Avocado integration
   test harness.

 - QEMU_JOB_PUBLISH - jobs that publish content after the
   branch is merged upstream

As build-tools-and-docs runs on master we declare the requirement of
building amd64-debian-container optional as it should already exits
once we merge.

00125414ba gitlab: convert Cirrus jobs to .base_job_template
This folds the Cirrus job rules into the base job
template, introducing two new variables

  - QEMU_JOB_CIRRUS - identifies the job as making
    use of Cirrus CI via cirrus-run

  - QEMU_JOB_OPTIONAL - identifies the job as one
    that is not run by default, primarily due to
    resource constraints. It can be manually invoked
    by users if they wish to validate that scenario.

6a0e7ea7b8 gitlab: introduce a common base job template
Currently job rules are spread across the various templates
and jobs, making it hard to understand exactly what runs in
what scenario. This leads to inconsistency in the rules and
increased maint burden.

The intent is that we introduce a common '.base_job_template'
which will have a general purpose 'rules:' block. No other
template or job should define 'rules:', but instead they must
rely on the inherited rules. To allow behaviour to be tweaked,
rules will be influenced by a number of variables with the
naming scheme 'QEMU_JOB_nnnn'.

f21db42631 configure: remove unused variables from config-host.mak
The only compiler variable that is still needed is $(CC), for
contrib/plugins/Makefile.  All firmware builds have their own
config-host.mak file.

d695918f7b configure: enable cross compilation of vof
While container-based cross compilers are not supported, this already
makes it possible to build vof on any machine that has an installation
of GCC and binutils for 32- or 64-bit PowerPC.
