2011-07-21Introduce compiler.h header fileLuiz Capitulino1-24/+1
This moves compiler related macros from qemu-common.h to compiler.h. The reason for this change is that there are simple header files that depend only on the compiler macros, so including qemu-common.h is overkill. Besides, qemu-common.h is bloated and will benefit from some splitting. Please, also note that the QEMU_BUILD_BUG_ON() macro is being fixed to not use double underscores as a prefix and the license text was added by Vassili Karpov (malc), who is one of the authors of the new file.

2011-07-12Remove unneeded setjmp.h (fix compilation on Debian "lenny")Stefan Weil1-1/+0
Some versions of png.h cannot be included after setjmp.h, even when PNG_SKIP_SETJMP_CHECK was defined. setjmp.h was included from qemu-common.h and is not needed there.

2011-06-24w32: Remove redundant definitions of PRI*64Stefan Weil1-5/+0
The PRI*64 macros are defined in MinGW's inttypes.h since 2002, so they are not needed in qemu-common.h (which includes inttypes.h). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2011-06-14cocoa: Provide central qemu_main() prototypeAndreas Färber1-0/+5
This fixes a missing prototype warning in vl.c and obsoletes the prototype in cocoa.m. Adjust callers in cocoa.m to supply third argument, which is currently only used on Linux/ppc. The prototype is designed so that it could be shared with SDL and other frontends, if desired. Cc: Alexandre Raymond <cerbere@gmail.com> Signed-off-by: Andreas Färber <andreas.faerber@web.de>

2011-05-15w32: Fix missing declaration of ffs()Stefan Weil1-5/+0
target-ppc/cpu.h now needs ffs(), too, so ffs() must be declared before this file is included. Moving the declaration from qemu-common.h to qemu-os-win32.h (which is included in qemu-common.h early) fixes the compiler warning for w32.

2011-04-15enable vm_clock to "warp" in the iothread+icount casePaolo Bonzini1-0/+1
The previous patch however is not enough, because if the virtual CPU goes to sleep waiting for a future timer interrupt to wake it up, qemu deadlocks. The timer interrupt never comes because time is driven by icount, but the vCPU doesn't run any insns. You could say that VCPUs should never go to sleep in icount mode if there is a pending vm_clock timer; rather time should just warp to the next vm_clock event with no sleep ever taking place. Even better, you can sleep for some time related to the time left until the next event, to avoid that the warps are too visible externally; for example, you could be sending network packets continously instead of every 100ms. This is what this patch implements. qemu_clock_warp is called: 1) whenever a vm_clock timer is adjusted, to ensure the warp_timer is synchronized; 2) at strategic points in the CPU thread, to make sure the insn counter is synchronized before the CPU starts running. In any case, the warp_timer is disabled while the CPU is running, because the insn counter will then be making progress on its own.

2011-03-29add a service to reap zombies, use it in SLIRPPaolo Bonzini1-0/+1
SLIRP -smb support wants to fork a process and forget about reaping it. To please it, add a generic service to register a process id and let QEMU reap it. In the future it could be enhanced to pass a status, but this would be unused. With this in place, the SIGCHLD signal handler would not stomp on pclose anymore.

2011-02-10QCOW2: bug fix - read base image beyond its sizeChunqiang Tang1-0/+2
This patch fixes the following bug in QCOW2. For a QCOW2 image that is larger than its base image, when handling a read request straddling over the end of the base image, the QCOW2 driver attempts to read beyond the end of the base image and the request would fail. This bug was found by Fast Virtual Disk (FVD)'s fully automated testing tool. The following test triggered the bug. dd if=/dev/zero of=/var/ramdisk/truth.raw count=0 bs=1 seek=1098561536 dd if=/dev/zero of=/var/ramdisk/zero-500M.raw count=0 bs=1 seek=593099264 ./qemu-img create -f qcow2 -ocluster_size=65536,backing_fmt=blksim -b /var/ramdisk/zero-500M.raw /var/ramdisk/test.qcow2 1098561536 ./qemu-io --auto --seed=30477694 --truth=/var/ramdisk/truth.raw --format=qcow2 --test=blksim:/var/ramdisk/test.qcow2 --verify_write=true --compare_before=false --compare_after=true --round=100000 --parallel=100 --io_size=10485760 --fail_prob=0 --cancel_prob=0 --instant_qemubh=true Signed-off-by: Chunqiang Tang <ctang@us.ibm.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

Move timer init functions to a new file, qemu-timer-common.c.

2010-10-03Replace most gcc format attributes by macro GCC_FMT_ATTR (format checking)Stefan Weil1-2/+1
Since version 4.4.x, gcc supports additional format attributes. __attribute__ ((format (gnu_printf, 1, 2))) should be used instead of __attribute__ ((format (printf, 1, 2)) because QEMU always uses standard format strings (even with mingw32). The patch replaces format attribute printf / __printf__ by macro GCC_FMT_ATTR which uses gnu_printf if supported. It also removes an #ifdef __GNUC__ (not needed any longer).

2010-06-15cow: stop using mmapChristoph Hellwig1-3/+0
We don't have an equivalent to mmap in the qemu block API, so read and write the bitmap directly. At least in the dumb implementation added in this patch this is a lot less efficient, but it means cow can also work on windows, and over nbd or curl.
