2020-08-05gitlab-ci: Fix Avocado cache usageThomas Huth1-6/+19
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.

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.

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.

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.

2020-08-03hw/intc/armv7m_nvic: Provide default "reset the system" behaviour for ↵Peter Maydell2-2/+19
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.

2020-08-03qcow2: Release read-only bitmaps when inactivatedMax Reitz1-4/+19
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).

2020-08-03schemas: Add vim modelineAndrea Bolognani35-0/+36
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. Signed-off-by: Andrea Bolognani <abologna@redhat.com> Message-Id: <20200729185024.121766-1-abologna@redhat.com> Reviewed-by: Daniel P.

2020-08-03qapi/machine.json: Fix missing newline in doc commentPeter Maydell1-1/+2
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.

2020-07-30tracetool: carefully define SDT_USE_VARIADICStefan Hajnoczi1-0/+4
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.

We try to go to wakeable sleep, so that, if drain begins it will break the sleep. But what if nbd_client_co_drain_begin() already called and s->drained is already true? We'll go to sleep, and drain will have to wait for the whole timeout. Let's improve it.

2020-07-28block/nbd: on shutdown terminate connection attemptVladimir Sementsov-Ogievskiy1-4/+11
On shutdown nbd driver may be in a connecting state. We should shutdown it as well, otherwise we may hang in nbd_teardown_connection, waiting for conneciton_co to finish in BDRV_POLL_WHILE(bs, s->connection_co) loop if remote server is down. How to reproduce the dead lock: 1. Create nbd-fault-injector.conf with the following contents: [inject-error "mega1"] event=data io=readwrite when=before 2. In one terminal run nbd-fault-injector in a loop, like this: n=1; while true; do echo $n; ((n++)); ./nbd-fault-injector.py 127.0.0.1:10000 nbd-fault-injector.conf; done 3.

Note, that this hang may be triggered by another bug, so the whole case is fixed only together with commit "block/nbd: allow drain during reconnect attempt".

2020-07-28block/nbd: allow drain during reconnect attemptVladimir Sementsov-Ogievskiy1-0/+14
It should be safe to reenter qio_channel_yield() on io/channel read/write path, so it's safe to reduce in_flight and allow attaching new aio context. And no problem to allow drain itself: connection attempt is not a guest request. Moreover, if remote server is down, we can hang in negotiation, blocking drain section and provoking a dead lock. How to reproduce the dead lock: 1. Create nbd-fault-injector.conf with the following contents: [inject-error "mega1"] event=data io=readwrite when=before 2.
