When a coprocessor instruction in an AArch32 guest traps to AArch32
Hyp mode, the syndrome register (HSR) includes Rt and Rt2 fields
which are simply copies of the Rt and Rt2 fields from the trapped
instruction. However, if the instruction is trapped from AArch32 to
an AArch64 higher exception level, the Rt and Rt2 fields in the
syndrome register (ESR_ELx) must be the AArch64 view of the register.
This makes a difference if the AArch32 guest was in a mode other than
User or System and it was using r13 or r14, or if it was in FIQ mode
and using r8-r14.
We don't know at translate time which AArch32 CPU mode we are in, so
we leave the values we generate in our prototype syndrome register
value at translate time as the raw Rt/Rt2 from the instruction, and
instead correct them to the AArch64 view when we find we need to take
an exception from AArch32 to AArch64 with one of these syndrome
values.

When calculating the offset, the result of left shift operation will be promoted
to type int64 automatically because the left operand of + operator is uint64_t.
but the result after integer promotion may be produce an error value for us and
trigger the following asserting error.
For example, consider i=0x2000, cluster_bits=18, the result of left shift
operation will be 0x80000000. Cause argument i is of signed integer type,
the result is automatically promoted to 0xffffffff80000000 which is not
we expected
The way to trigger the assertion error:
qemu-img create -f qcow2 -o preallocation=full,cluster_size=256k tmpdisk 10G
This patch fix it by casting @i to uint64_t before doing left shift operation

In commit 6957fd98dc ("gitlab: add avocado asset caching") we
tried to save the Avocado cache (as in commit c1073e44b4 with
Travis-CI) however it doesn't work as expected. For some reason
Avocado uses /root/avocado_cache/ which we can not select later.
Manually generate a Avocado config to force the use of the
current job's directory.
This patch is based on an earlier version from Philippe Mathieu-Daudé.

We were missing the two new targets avr-softmmu and rx-softmmu in the
gitlab-CI so far, and did not add some of the "other endianess" targets
like sh4eb-softmmu yet.
Since the current build-system-* jobs run already for a very long time,
let's do not add these missing targets there, but introduce two new
additional build jobs, one running with Debian and one running with
CentOS, and add the new targets there. Also move some targets from
the old build-system-* jobs to these new targets, to distribute the
load and reduce the runtime of the CI.

Without python3-venv, I get the following message when trying to
run the acceptance tests within the debian container:
The virtual environment was not created successfully because ensurepip is not

package using the following command.
apt-get install python3-venv
You may need to use sudo with that command. After installing the python3-venv

Let's do it as the message suggests.
And while we're at it, also add netcat here since it is required for

This likely affects other, less popular host architectures as well.
Less common host architectures under linux get QEMU_VMALLOC_ALIGN (from
which VIRTIO_MEM_MIN_BLOCK_SIZE is derived) define to a variable of
type uintptr, which isn't compatible with the format specifier used to
print a user message. Since this particular usage of the underlying data
seems unique to this file, the simple fix is to just cast
QEMU_VMALLOC_ALIGN to uint32_t, which corresponds to the format specifier
used.

CONFIG_XEN is generated by configure and stored in "config-target.h",
which is (obviously) only include for target-specific objects.
This is a problem for target-agnostic objects as CONFIG_XEN is never

Fix by following the KVM schema, defining CONFIG_XEN_IS_POSSIBLE
when we don't know to force the call of the non-inlined function,

The imx_epit device has a software-controllable reset triggered by
setting the SWR bit in the CR register. An error in commit cc2722ec83ad9
means that we will end up assert()ing if the guest does this, because
the code in imx_epit_write() starts ptimer transactions, and then
imx_epit_reset() also starts ptimer transactions, triggering
"ptimer_transaction_begin: Assertion `!s->in_transaction' failed".
The cleanest way to avoid this double-transaction is to move the
start-transaction for the CR write handling down below the check of
the SWR bit.

The nrf51 SoC model wasn't setting the system_clock_scale
global.which meant that if guest code used the systick timer in "use
the processor clock" mode it would hang because time never advances.
Set the global to match the documented CPU clock speed for this SoC.
This SoC in fact doesn't have a SysTick timer (which is the only thing
currently that cares about the system_clock_scale), because it's
a configurable option in the Cortex-M0. However our Cortex-M0 and
thus our nrf51 and our micro:bit board do provide a SysTick, so
we ought to provide a functional one rather than a broken one.

The definition of top_bit used in this function is one higher
than that used in the Arm ARM psuedo-code, which put the error
indication at top_bit - 1 at the wrong place, which meant that
it wasn't visible to Auth.
Fixing the definition of top_bit requires more changes, because
its most common use is for the count of bits in top_bit:bot_bit,
which would then need to be computed as top_bit - bot_bit + 1.
For now, prefer the minimal fix to the error indication alone.

SYSRESETREQ
The NVIC provides an outbound qemu_irq "SYSRESETREQ" which it signals
when the guest sets the SYSRESETREQ bit in the AIRCR register. This
matches the hardware design (where the CPU has a signal of this name
and it is up to the SoC to connect that up to an actual reset
mechanism), but in QEMU it mostly results in duplicated code in SoC
objects and bugs where SoC model implementors forget to wire up the
SYSRESETREQ line.
Provide a default behaviour for the case where SYSRESETREQ is not
actually connected to anything: use qemu_system_reset_request() to
perform a system reset. This will allow us to remove the
implementations of SYSRESETREQ handling from the boards where that's
exactly what it does, and also fixes the bugs in the board models
which forgot to wire up the signal:
* microbit
* mps2-an385
* mps2-an505
* mps2-an511
* mps2-an521
* musca-a
* musca-b1
* netduino
* netduinoplus2
We still allow the board to wire up the signal if it needs to, in case
we need to model more complicated reset controller logic or to model
buggy SoC hardware which forgot to wire up the line itself. But
defaulting to "reset the system" is more often going to be correct
than defaulting to "do nothing".

Mostly devices don't need to care whether one of their output
qemu_irq lines is connected, because functions like qemu_set_irq()
silently do nothing if there is nothing on the other end. However
sometimes a device might want to implement default behaviour for the
case where the machine hasn't wired the line up to anywhere.
Provide a function qemu_irq_is_connected() that devices can use for
this purpose. (The test is trivial but encapsulating it in a
function makes it easier to see where we're doing it in case we need
to change the implementation later.)

Set the global to match the documented CPU clock speed of these boards.
Judging by the data sheet this is slightly simplistic because the

RCC (reset and clock control) module, but we don't model that.

During migration, we release all bitmaps after storing them on disk, as
long as they are (1) stored on disk, (2) not read-only, and (3)
consistent.
(2) seems arbitrary, though. The reason we do not release them is
because we do not write them, as there is no need to; and then we just
forget about all bitmaps that we have not written to the file. However,
read-only persistent bitmaps are still in the file and in sync with
their in-memory representation, so we may as well release them just like
any R/W bitmap that we have updated.
It leads to actual problems, too: After migration, letting the source
continue may result in an error if there were any bitmaps on read-only
nodes (such as backing images), because those have not been released by
bdrv_inactive_all(), but bdrv_invalidate_cache_all() attempts to reload
them (which fails, because they are still present in memory).

The various schemas included in QEMU use a JSON-based format which
is, however, strictly speaking not valid JSON.
As a consequence, when vim tries to apply syntax highlight rules
for JSON (as guessed from the file name), the result is an unreadable
mess which mostly consist of red markers pointing out supposed errors
in, well, pretty much everything.
Using Python syntax highlighting produces much better results, and
in fact these files already start with specially-formatted comments
that instruct Emacs to process them as if they were Python files.
This commit adds the equivalent special comments for vim.

In commit 176d2cda0dee9f4 we added the @die-id field
to the CpuInstanceProperties struct, but in the process
accidentally removed the newline between the doc-comment
lines for @core-id and @thread-id.
Put the newline back in; this fixes a misformatting in the
generated HTML QMP reference manual.

tracetool: carefully define SDT_USE_VARIADIC
trace/simple: Allow enabling simple traces from command line
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

The dtrace backend defines SDT_USE_VARIADIC as a workaround for a
conflict with a LTTng UST header file, which requires SDT_USE_VARIADIC
to be defined.
LTTng UST <lttng/tracepoint.h> breaks if included after generated dtrace
headers because SDT_USE_VARIADIC will already be defined:
#ifdef LTTNG_UST_HAVE_SDT_INTEGRATION
#define SDT_USE_VARIADIC <-- error, it's already defined
#include <sys/sdt.h>
Be more careful when defining SDT_USE_VARIADIC. This fixes the build
when both the dtrace and ust tracers are enabled at the same time.

As pointed out by Peter, g_memdup(ms->loadparm, sizeof(ms->loadparm) + 1)
reads one past of the end of ms->loadparm, so g_memdup() can not be used
here.
Let's use g_strndup instead!

The simple trace backend is enabled / disabled with a call
to st_set_trace_file_enabled(). When initializing tracing
from the command-line, this must be enabled on startup.
(Prior to db25d56c014aa1a9, command-line initialization of
simple trace worked because every call to st_set_trace_file
enabled tracing.)
