2013-06-14create qemu_openpty_raw() helper function and move it to a separate fileMichael Tokarev2-1/+136
In two places qemu uses openpty() which is very system-dependent, and in both places the pty is switched to raw mode as well. Make a wrapper function which does both steps, and move all the system-dependent complexity into a separate file, together with static/local implementations of openpty() and cfmakeraw() from qemu-char.c. It is in a separate file, not part of oslib-posix.c, because openpty() often resides in -lutil which is not linked to every program qemu builds. This change removes #including of <pty.h>, <termios.h> and other rather specific system headers out of qemu-common.h, which isn't a place for such specific headers really. This version has been verified to build correctly on Linux, OpenBSD, FreeBSD and OpenIndiana. On the latter it lets qemu to be built with gtk gui which were not possible there due to missing openpty() and cfmakeraw().

2013-04-29win32: add readv/writev emulationPaolo Bonzini2-1/+44
Commit e9d8fbf (qemu-file: do not use stdio for qemu_fdopen, 2013-03-27) introduced a usage of writev, which mingw32 does not have. Even though qemu_fdopen itself is not used on mingw32, the future-proof solution is to add an implementation of it. This is simple and similar to how we emulate sendmsg/recvmsg in util/iov.c. Some files include osdep.h without qemu-common.h, so move the definition of iovec to osdep.h too, and include osdep.h from qemu-common.h unconditionally (protection against including files when NEED_CPU_H is defined is not needed since the removal of AREG0).

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.

this adds buffer_find_nonzero_offset() which is a SSE2/Altivec optimized function that searches for non-zero content in a buffer. the function starts full unrolling only after the first few chunks have been checked one by one. analyzing real memory page data has revealed that non-zero pages are non-zero within the first 256-512 bits in most cases. as this function is also heavily used to check for zero memory pages this tweak has been made to avoid the high setup costs of the fully unrolled check for non-zero pages. due to the optimizations used in the function there are restrictions on buffer address and search length. the function can_use_buffer_find_nonzero_content() can be used to check if the function can be used safely.
