2009-09-12Add #defines needed by OpenSolaris, fix breakage by the #definesBlue Swirl
We need to define _XOPEN_SOURCE and __EXTENSIONS__ macros in order to get CMSG_ and TIOCWIN macros defined. But then _POSIX_C_SOURCE gets defined, which is (incorrectly) used as an indicator for existence of posix_memalign() in osdep.c. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-08-24Unbreak large mem support by removing kqemuAnthony Liguori
kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-05-13Add tool_osdep.cPaul Brook
osdep.c is built in both as a toplevel target independant object, and as a per-target object because of kqemu dependencies. Under some circumstances make picks up the wrong one. Build the former as tool-osdep to avoid this conflict. Signed-off-by: Paul Brook <paul@codesourcery.com>

2008-11-11Fix -linux-user build by reverting r5701aliguori
Unfortunately, -linux-user doesn't use osdep as it replaces some of those functions with specific ones. The code #ifdef code in exec.c needs to remain in place so instead of introducing a qemu_getpagesize() let's just use getpagesize() in the non-Windows implementation of qemu_vmalloc.

2008-09-15Use common objects for qemu-img and qemu-nbdaliguori
Right now, we sprinkle #if defined(QEMU_IMG) && defined(QEMU_NBD) all over the code. It's ugly and causes us to have to build multiple object files for linking against qemu and the tools. This patch introduces a new file, qemu-tool.c which contains enough for qemu-img, qemu-nbd, and QEMU to all share the same objects. This also required getting qemu-nbd to be a bit more Windows friendly. I also changed the Windows block-raw to use normal IO instead of overlapping IO since we don't actually do AIO yet on Windows. I changed the various #if 0's to #if WIN32_AIO to make it easier for someone to eventually fix AIO on Windows. After this patch, there are no longer any #ifdef's related to qemu-img and qemu-nbd.
