2013-01-19tci: Fix broken build (regression)Stefan Weil
s390x-linux-user now also uses GETPC. Instead of adding it to the list of targets which use GETPC, the macro is now defined unconditionally. This avoids future build regressions like this one: CC s390x-linux-user/target-s390x/int_helper.o cc1: warnings being treated as errors qemu/target-s390x/int_helper.c: In function ‘helper_divs32’: qemu/target-s390x/int_helper.c:47: error: implicit declaration of function ‘GETPC’ qemu/target-s390x/int_helper.c:47: error: nested extern declaration of ‘GETPC’ Signed-off-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2013-01-12fdt: Use bswapN instead of bswap_NRichard Henderson
Fixes the libfdt enabled build for hosts that have <machine/bswap.h>. The code at the beginning of qemu/bswap.h is attempting to standardize on bswapN. In the case of CONFIG_MACHINE_BSWAP_H, this is all we get. In the case of CONFIG_BYTESWAP_H, we get bswap_N from the system header and then wrap these with inline functions to get bswapN.

2013-01-10Make all static TypeInfos constAndreas Färber
Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all types natively through QEMU Object Model), TypeInfo as used in the common, non-iterative pattern is no longer amended with information and should therefore be const. Fix the documented QOM examples: sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h Since frequently the wrong examples are being copied by contributors of new devices, fix all types in the tree: sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c This also avoids to piggy-back these changes onto real functional changes or other refactorings.

2013-01-02iov: add qemu_iovec_concat_iov()Stefan Hajnoczi
The qemu_iovec_concat() function copies a subset of a QEMUIOVector. The new qemu_iovec_concat_iov() function does the same for a iov/cnt pair. It is easy to define qemu_iovec_concat() in terms of qemu_iovec_concat_iov(). The existing code is mostly unchanged, except for the assertion src->size >= soffset, which cannot be efficiently checked upfront on a iov/cnt pair. Instead we assert upon hitting the end of src with an unsatisfied soffset. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
2013-01-02iov: add iov_discard_front/back() to remove dataStefan Hajnoczi

2013-01-02raw-posix: add raw_get_aio_fd() for virtio-blk-data-planeStefan Hajnoczi
The raw_get_aio_fd() function allows virtio-blk-data-plane to get the file descriptor of a raw image file with Linux AIO enabled. This interface is really a layering violation that can be resolved once the block layer is able to run outside the global mutex - at that point virtio-blk-data-plane will switch from custom Linux AIO code to using the block layer.

2012-12-20savevm: New save live migration method: pendingJuan Quintela
Code just now does (simplified for clarity) if (qemu_savevm_state_iterate(s->file) == 1) { vm_stop_force_state(RUN_STATE_FINISH_MIGRATE); qemu_savevm_state_complete(s->file); } Problem here is that qemu_savevm_state_iterate() returns 1 when it knows that remaining memory to sent takes less than max downtime. But this means that we could end spending 2x max_downtime, one downtime in qemu_savevm_iterate, and the other in qemu_savevm_state_complete. Changed code to: pending_size = qemu_savevm_state_pending(s->file, max_size); DPRINTF("pending size %lu max %lu\n", pending_size, max_size); if (pending_size >= max_size) { ret = qemu_savevm_state_iterate(s->file); } else { vm_stop_force_state(RUN_STATE_FINISH_MIGRATE); qemu_savevm_state_complete(s->file); } So what we do is: at current network speed, we calculate the maximum number of bytes we can sent: max_size. Then we ask every save_live section how much they have pending. If they are less than max_size, we move to complete phase, otherwise we do an iterate one. This makes things much simpler, because now individual sections don't have to caluclate the bandwidth (it was implossible to do right from there).
