2013-04-17libqos: add malloc supportAnthony Liguori4-0/+130
This is a very simple allocator for the PC platform. It should be possible to add backends for other platforms. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-id: 1366123521-4330-5-git-send-email-aliguori@us.ibm.com

2013-04-16migration: initialize RAM to zeroPaolo Bonzini1-17/+18
Using qemu_memalign only leaves the RAM zero by chance, because libc will usually use mmap to satisfy our huge requests. But memory will not be zero when using MALLOC_PERTURB_ with a nonzero value. In the case of incoming migration, this breaks a recently-introduced invariant (commit f1c7279, migration: do not sent zero pages in bulk stage, 2013-03-26). To fix this, use mmap ourselves to get a well-aligned, always zero block for the RAM. Mmap-ed memory is easy to "trim" at the sides. This also removes the need to do something special on valgrind (see commit c2a8238a, Support running QEMU on Valgrind, 2011-10-31), thus effectively reverts that patch.

2013-04-16use libusb for usb-hostGerd Hoffmann4-2/+1501
Reimplement usb-host on top of libusb. Reasons to do this: (1) Largely rewritten from scratch, nice opportunity to kill historical cruft. (2) Offload usbfs handling to libusb. (3) Have a single portable code base instead of bsd + linux variants. (4) Bring usb-host support to any platform supported by libusbx. For now this goes side-by-side to the existing code. That is only to simplify regression testing though, at the end of the day I want remove the old code and support libusb exclusively. Merge early in 1.5 cycle, remove the old code after 1.5 release or something like this. Thanks to qdev the old and new code can coexist nicely on linux. Just use "-device usb-host-linux" to use the old linux driver instead of the libusb one (which takes over the "usb-host" name). The bsd driver isn't qdev'ified so it isn't that easy for bsd. I didn't bother making it runtime switchable, so you have to rebuild qemu with --disable-libusb to get back the old code. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2013-04-16spice-qemu-char: vmc_write: Don't write more bytes then we're asked tooHans de Goede1-1/+2
This one took me eons to debug, but I've finally found it now, oh well. The usage of the MIN macro in this line: last_out = MIN(len, qemu_chr_be_can_write(scd->chr)); Causes qemu_chr_be_can_write to be called *twice*, since the MIN macro evaluates its arguments twice (bad MIN macro, bad!). And the result of the call can change between the 2 calls since the guest may have consumed some data from the virtio ringbuffer between the calls! When this happens it is possible for qemu_chr_be_can_write to return less then len in the call made for the comparision, and then to return more then len in the actual call for the return-value of MIN, after which we will end up writing len data + some extra garbage, not good.

2013-04-16spice-qemu-char: Remove intermediate bufferAlon Levy1-9/+3

Then vmc_read is called back, we return 0 (not accessing the buffer) and set the timer to unthrottle. Also make datalen int and not ssize_t (to fit spice_chr_write signature).
