2015-11-10Rename save_live_complete to save_live_complete_precopyDr. David Alan Gilbert
In postcopy we're going to need to perform the complete phase for postcopiable devices at a different point, start out by renaming all of the 'complete's to make the difference obvious.

2015-11-10Add wrapper for setting blocking status on a QEMUFileDr. David Alan Gilbert
Add a wrapper to change the blocking status on a QEMUFile rather than having to use qemu_set_block(qemu_get_fd(f)); it seems best to avoid exposing the fd since not all QEMUFile's really have one. With this wrapper we could move the implementation down to be different on different transports.

2015-11-10Add qemu_get_buffer_in_place to avoid copies some of the timeDr. David Alan Gilbert
qemu_get_buffer always copies the data it reads to a users buffer, however in many cases the file buffer inside qemu_file could be given back to the caller, avoiding the copy. This isn't always possible depending on the size and alignment of the data. Thus 'qemu_get_buffer_in_place' either copies the data to a supplied buffer or updates a pointer to the internal buffer if convenient.

2015-11-10qemu_ram_block_from_hostDr. David Alan Gilbert
Postcopy sends RAMBlock names and offsets over the wire (since it can't rely on the order of ramaddr being the same), and it starts out with HVA fault addresses from the kernel. qemu_ram_block_from_host translates a HVA into a RAMBlock, an offset in the RAMBlock and the global ram_addr_t value. Rewrite qemu_ram_addr_from_host to use qemu_ram_block_from_host. Provide qemu_ram_get_idstr since its the actual name text sent on the wire.

2015-11-10qapi: Simplify error cleanup in test-qmp-*Eric Blake
We have several tests that perform multiple sub-actions that are expected to fail. Asserting that an error occurred, then clearing it up to prepare for the next action, turned into enough boilerplate that it was sometimes forgotten (for example, a number of tests added to test-qmp-input-visitor.c in d88f5fd leaked err). Worse, if an error is not reset to NULL, we risk invalidating later use of that error (passing a non-NULL err into a function is generally a bad idea). Encapsulate the boilerplate into a single helper function error_free_or_abort(), and consistently use it. The new function is added into error.c for use everywhere, although it is anticipated that testsuites will be the main client.

2015-11-09aio: Introduce aio-epoll.cFam Zheng
To minimize code duplication, epoll is hooked into aio-posix's aio_poll() instead of rolling its own. This approach also has both compile-time and run-time switchability. 1) When QEMU starts with a small number of fds in the event loop, ppoll is used. 2) When QEMU starts with a big number of fds, or when more devices are hot plugged, epoll kicks in when the number of fds hits the threshold. 3) Some fds may not support epoll, such as tty based stdio. In this case, it falls back to ppoll. A rough benchmark with scsi-disk on virtio-scsi dataplane (epoll gets enabled from 64 onward). Numbers are in MB/s. =============================================== | master | epoll | | scsi disks # | read randrw | read randrw -------------|----------------|---------------- 1 | 86 36 | 92 45 8 | 87 43 | 86 41 64 | 71 32 | 70 38 128 | 48 24 | 58 31 256 | 37 19 | 57 28 =============================================== To comply with aio_{disable,enable}_external, we always use ppoll when aio_external_disabled() is true.

2015-11-06replay: recording and replaying clock ticksPavel Dovgalyuk
Clock ticks are considered as the sources of non-deterministic data for virtual machine. This patch implements saving the clock values when they are acquired (virtual, host clock). When replaying the execution corresponding values are read from log and transfered to the module, which wants to read the values. Such a design required the clock polling to be synchronized. Sometimes it is not true - e.g. when timeouts for timer lists are checked. In this case we use a cached value of the clock, passing it to the client code.

The default CPU model (qemu64) have some issues today: it enables some features (ABM and SSE4a) that are not present in many host CPUs. That means many hosts (but not all of them) had those features silently disabled in the default configuration in QEMU 2.4 and older. With the new "check=on" default, this causes warnings to be printed in the default configuration, because of the lack of SSE4A on all Intel hosts, and the lack of ABM on Sandy Bridge and older hosts: $ qemu-system-x86_64 -machine pc,accel=kvm warning: host doesn't support requested feature: CPUID.80000001H:ECX.abm [bit 5] warning: host doesn't support requested feature: CPUID.80000001H:ECX.sse4a [bit 6] Those issues will be fixed in pc-*-2.5 and newer.

2015-11-03armv7-m: Return DeviceState* from armv7m_init()Michael Davidsaver
Change armv7m_init to return the DeviceState* for the NVIC. This allows access to all GPIO blocks, not just the IRQ inputs. Move qdev_get_gpio_in() calls out of armv7m_init() into board code for stellaris and stm32f205 boards.

2015-11-03arm: boot: Add board specific setup code APIPeter Crosthwaite
Add an API for boards to inject their own preboot software (or firmware) sequence. The software then returns to the bootloader via the link register. This allows boards to do their own little bits of firmware setup without needed to replace the bootloader completely (which is the requirement for existing firmware support). The blob is loaded by a callback if and only if doing a linux boot (similar to the existing write_secondary support). Rewrite the comment for the primary boot blob.
