2018-07-02s390x/tcg: fix locking problem with tcg_s390_tod_updatedDavid Hildenbrand1-10/+16
tcg_s390_tod_updated() is always called with the iothread being locked (e.g. from S390TODClass->set() e.g. via HELPER(sck) or on incoming migration). The helper we call takes the lock itself - bad. Let's change that by factoring out updating the ckc timer. This now looks much nicer than having to call a helper from another function. While touching it we also make sure that env->ckc is updated even if the new value is -1ULL, for now it would not have been modified in that case.

2018-07-02s390x/kvm: indicate alignment in legacy_s390_alloc()David Hildenbrand1-0/+3
Let's do this for completeness reason, although we don't support e.g. PCDIMM/NVDIMM, which would use the alignment for placing the memory region in guest physical memory. But maybe someday we would want to support something like this - then we don't forget about this if allowing multiple allocations in legacy_s390_alloc(). Use the same alignment as we would set in qemu_anon_ram_alloc(). Our fixed address satisfies this alignment (1MB). This implicitly sets the alignment of the underlying memory region.

We always allocate at a fixed address, a second allocation can therefore of course never work. We would simply overwrite mappings. This can e.g. happen in s390_memory_init(), if trying to allocate more than > 8TB. Let's just bail out, as there is no need for supporting it (legacy handling for z/VM).

2018-07-02s390x/tcg: fix CPU hotplug with single-threaded TCGDavid Hildenbrand1-5/+12
run_on_cpu() doesn't seem to work reliably until the CPU has been fully created if the single-threaded TCG main loop is already running. Therefore, hotplugging a CPU under single-threaded TCG does currently not work. We should use the direct call instead of going via run_on_cpu(). So let's use run_on_cpu() for KVM only - KVM requires it due to the initial CPU reset ioctl. As a nice side effect, we get rid of the ifdef.

2018-07-02s390x/tcg: properly implement the TODDavid Hildenbrand8-34/+109
Right now, each CPU has its own TOD. Especially, the TOD will differ based on creation time of a CPU - e.g. when hotplugging a CPU the times will differ quite a lot, resulting in stall warnings in the guest. Let's use a single TOD by implementing our new TOD device. Prepare it for TOD-clock epoch extension. Most importantly, whenever we set the TOD, we have to update the CKC timer. Introduce "tcg_s390x.h" just like "kvm_s390x.h" for tcg specific function declarations that should not go into cpu.h.

The rom_ptr() function allows direct access to the ROM blobs that we load during startup. However, there are currently no checks for the size of the accesses, so it's currently possible to crash QEMU for example with: $ echo "Insane in the mainframe" > /tmp/test.txt $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -append xyz Segmentation fault (core dumped) $ s390x-softmmu/qemu-system-s390x -kernel /tmp/test.txt -initrd /tmp/test.txt Segmentation fault (core dumped) $ echo -n HdrS > /tmp/hdr.txt $ sparc64-softmmu/qemu-system-sparc64 -kernel /tmp/hdr.txt -initrd /tmp/hdr.txt Segmentation fault (core dumped) We need a possibility to check the size of the ROM area that we want to access, thus let's add a size parameter to the rom_ptr() function to avoid these problems.

With the latest refactoring this is now broken when -no-reboot is used or when libvirt acts on a reboot QMP event, for example a virt-install from iso images.

2018-06-30xtensa: Avoid calling get_page_addr_code() from helper functionPeter Maydell1-1/+5
The xtensa frontend calls get_page_addr_code() from its itlb_hit_test helper function. This function is really part of the TCG core's internals, and calling it from a target helper makes it awkward to make changes to that core code. It also means that we don't pass the correct retaddr to tlb_fill(), so we won't correctly handle the case where an exception is generated. The helper is used for the instructions IHI, IHU and IPFL.

2018-06-30monitor: flush qmp responses when CLOSEDPeter Xu1-3/+29
Previously we clean up the queues when we got CLOSED event. It was used to make sure we won't send leftover replies/events of a old client to a new client which makes perfect sense. However this will also drop the replies/events even if the output port of the previous chardev backend is still open, which can lead to missing of the last replies/events. Now this patch does an extra operation to flush the response queue before cleaning up. In most cases, a QMP session will be based on a bidirectional channel (a TCP port, for example, we read/write to the same socket handle), so in port and out port of the backend chardev are fundamentally the same port. In these cases, it does not really matter much on whether we'll flush the response queue since flushing will fail anyway. However there can be cases where in & out ports of the QMP monitor's backend chardev are separated. Here is an example: cat $QMP_COMMANDS | qemu -qmp stdio ... | filter_commands In this case, the backend is fd-typed, and it is connected to stdio where in port is stdin and out port is stdout. Now if we drop all the events on the response queue then filter_command process might miss some events that it might expect. The thing is that, when stdin closes, stdout might still be there alive! In practice, I encountered SHUTDOWN event missing when running test with iotest 087 with Out-Of-Band enabled. Here is one of the ways that this can happen (after "quit" command is executed and QEMU quits the main loop): 1. [main thread] QEMU queues a SHUTDOWN event into response queue. 2. "cat" terminates (to distinguish it from the animal, I quote it). 3. [monitor iothread] QEMU's monitor iothread reads EOF from stdin. 4. [monitor iothread] QEMU's monitor iothread calls the CLOSED event hook for the monitor, which will destroy the response queue of the monitor, then the SHUTDOWN event is dropped. 5. [main thread] QEMU's main thread cleans up the monitors in monitor_cleanup(). When trying to flush pending responses, it sees nothing. SHUTDOWN is lost forever. Note that before the monitor iothread was introduced, step [4]/[5] could never happen since the main loop was the only place to detect the EOF event of stdin and run the CLOSED event hooks. Now things can happen in parallel in the iothread. Without this patch, iotest 087 will have ~10% chance to miss the SHUTDOWN event and fail when with Out-Of-Band enabled: --- /home/peterx/git/qemu/tests/qemu-iotests/087.out +++ /home/peterx/git/qemu/bin/tests/qemu-iotests/087.out.bad @@ -8,7 +8,6 @@ {"return": {}} {"error": {"class": "GenericError", "desc": "'node-name' must be specified for the root node"}} {"return": {}} -{"timestamp": {"seconds": TIMESTAMP, "microseconds": TIMESTAMP}, "event": "SHUTDOWN", "data": {"guest": false}} === Duplicate ID === @@ -53,7 +52,6 @@ {"return": {}} {"return": {}} {"return": {}} -{"timestamp": {"seconds": TIMESTAMP, "microseconds": TIMESTAMP}, "event": "SHUTDOWN", "data": {"guest": false}} This patch fixes the problem.

2018-06-30monitor: rename *_pop_one to *_pop_anyPeter Xu1-11/+9
The old names are confusing since both of the old functions are popping an item from multiple queues rather than a single queue. In that sense, *_pop_any() suites better than *_pop_one(). Since at it, touch up the function monitor_qmp_response_pop_any() a bit to let the callers pass in a QMPResponse struct instead of returning a struct. Change the return value to boolean to mark whether we have popped a valid response instead.

2018-06-29sd: Don't trace SDRequest crc fieldPeter Maydell2-2/+2
We don't actually implement SD command CRC checking, because for almost all of our SD controllers the CRC generation is done in hardware, and so modelling CRC generation and checking would be a bit pointless. (The exception is that milkymist-memcard makes the guest software compute the CRC.) As a result almost all of our SD controller models don't bother to set the SDRequest crc field, and the SD card model doesn't check it. So the tracing of it in sdbus_do_command() provokes Coverity warnings about use of uninitialized data. Drop the CRC field from the trace; we can always add it back if and when we do anything useful with the CRC. Fixes Coverity issues 1386072, 1386074, 1386076, 1390571.
