2014-08-06backends: Introduce chr-testdevPaolo Bonzini
From: Paolo Bonzini <pbonzini@redhat.com> chr-testdev enables a virtio serial channel to be used for guest initiated qemu exits. hw/misc/debugexit already enables guest initiated qemu exits, but only for PC targets. chr-testdev supports any virtio-capable target. kvm-unit-tests/arm is already making use of this backend. Currently there is a single command implemented, "q". It takes a (prefix) argument for the exit code, thus an exit is implemented by writing, e.g. "1q", to the virtio-serial port. It can be used as: $QEMU ... \ -device virtio-serial-device \ -device virtserialport,chardev=ctd -chardev testdev,id=ctd or, use: $QEMU ... \ -device virtio-serial-device \ -device virtconsole,chardev=ctd -chardev testdev,id=ctd to bind it to virtio-serial port0.

After commit f702e62 (serial: change retry logic to avoid concurrency, 2014-07-11), guest boot hangs if the backend is an unconnected PTY. The reason is that PTYs do not support G_IO_HUP, and serial_xmit is never called. To fix this, simply invoke serial_xmit immediately (via g_idle_source_new) when this happens.

2014-07-22vmstate_xhci_event: fix unterminated field listLaszlo Ersek
"vmstate_xhci_event" was introduced in commit 37352df3 ("xhci: add live migration support"), and first released in v1.6.0. The field list in this VMSD is not terminated with the VMSTATE_END_OF_LIST() macro. During normal use (ie. migration), the issue is practically invisible, because the "vmstate_xhci_event" object (with the unterminated field list) is only ever referenced -- via "vmstate_xhci_intr" -- if xhci_er_full() returns true, for the "ev_buffer" test. Since that field_exists() check (apparently) almost always returns false, we almost never traverse "vmstate_xhci_event" during migration, which hides the bug. However, Amit's vmstate checker forces recursion into this VMSD as well, and the lack of VMSTATE_END_OF_LIST() breaks the field list terminator check (field->name != NULL) in dump_vmstate_vmsd(). The result is undefined behavior, which in my case translates to infinite recursion (because the loop happens to overflow into "vmstate_xhci_intr", which then links back to "vmstate_xhci_event"). Add the missing terminator.

2014-07-22ppc: fix -mem-path failureHu Tao
commit e938ba0c tried to enable -mem-path for ppc but breaked some ppc boards. The problems are: 1. it fails when allocating memory for rom, sram whose sizes are less than huge page size: ./ppc-softmmu/qemu-system-ppc -m 512 -mem-path /hugepages/ \ -kernel /home/hutao/Downloads/vmlinux-ppc -initrd \ /home/hutao/Downloads/initrd-ppc.gz qemu-system-ppc: /mnt/data/projects/qemu/exec.c:1184: qemu_ram_set_idstr: Assertion `new_block' failed. 2. if there is a numa node backed by memory backend object, qemu fails with message: ./ppc-softmmu/qemu-system-ppc -m 512 \ -object memory-backend-file,size=512M,mem-path=/hugepages,id=f0 \ -numa node,nodeid=0,memdev=f0 \ -kernel /home/hutao/Downloads/vmlinux-ppc \ -initrd /home/hutao/Downloads/initrd-ppc.gz qemu-system-ppc: memory backend f0 is used multiple times. Each -numa option must use a different memdev value. This patch does following: 1. replaces memory_region_allocate_system_memory() with memory_region_init_ram() for rom, sram. Then only system memory is backed by hugepages when specifying mem-path. 2. for memory banks, allocates all ram with one memory_region_allocate_system_memory(), and use memory_region_init_alias() to initialize memory banks.

2014-07-22virtio-rng: Add human-readable error message for negative max-bytes parameterJohn Snow
If a negative integer is used for the max_bytes parameter, QEMU currently calls abort() and leaves behind a core dump. This patch replaces the abort with a simple error message to make the reason for the termination clearer. This also ensures device-hotplug with invalid input doesn't cause qemu to quit. There is an underlying insufficiency in the parameter parsing code of QEMU that renders it unable to reject negative values for unsigned properties, thus the error message "a non-negative integer below 2^63" is the most user-friendly and correct message we can give until the underlying insufficiency is corrected.

2014-07-22exec: fix migration with devices that use address_space_rwPaolo Bonzini
Devices that use address_space_rw to write large areas to memory (as opposed to address_space_map/unmap) were broken with respect to migration since fe680d0 (exec: Limit translation limiting in address_space_translate to xen, 2014-05-07). Such devices include IDE CD-ROMs. The reason is that invalidate_and_set_dirty (called by address_space_rw but not address_space_map/unmap) was only setting the dirty bit for the first page in the translation. To fix this, introduce cpu_physical_memory_set_dirty_range_nocode that is the same as cpu_physical_memory_set_dirty_range except it does not muck with the DIRTY_MEMORY_CODE bitmap. This function can be used if the caller invalidates translations with tb_invalidate_phys_page_range. There is another difference between cpu_physical_memory_set_dirty_range and cpu_physical_memory_set_dirty_flag; the former includes a call to xen_modified_memory. This is handled separately in invalidate_and_set_dirty, and is not needed in other callers of cpu_physical_memory_set_dirty_range_nocode, so leave it alone. Just one nit: now that invalidate_and_set_dirty takes care of handling multiple pages, there is no need for address_space_unmap to wrap it in a loop. In fact that loop would now be O(n^2).

2014-07-18module: Don't complain when a module is absentAndreas Färber
The current implementation depends on a configure-time generated list of block modules. When any of them is absent, module_load() emits a warning. This is suboptimal because extracting code to modules was mainly done to allow separate packaging of modules with intrusive dependencies. Absence of optional packages then leads to absence of modules and an error message, which users may recognize as new and report as error.

2014-07-18qemu-iotests: fix 028 failure due to disk image pathStefan Hajnoczi
The disk image path is echoed by QEMU's readline when the "drive_backup disk ${TEST_IMG}.copy" HMP command is issued. Unfortunately it is very hard to filter out the path due to readline's character-by-character output (with terminal escape sequences). Just redirect this command to /dev/null for now.

2014-07-18raw-posix: Fail gracefully if no working alignment is foundKevin Wolf
If qemu couldn't find out what O_DIRECT alignment to use with a given file, it would run into assert(bdrv_opt_mem_align(bs) != 0); in block.c and confuse users. This adds a more descriptive error message for such cases.
