2010-12-17Introduce strtosz_suffix()Jes Sorensen
This introduces strtosz_suffix() which allows the caller to specify a default suffix in case the non default of MB is wanted. strtosz() is kept as a wrapper for strtosz_suffix() which keeps it's current default of MB.

2010-11-03Introduce strtosz() library function to convert a string to a byte count.Jes Sorensen
strtosz() returns -1 on error. It now supports human unit formats in eg. 1.0G, with better error handling. The following suffixes are supported: B/b = bytes K/k = KB M/m = MB G/g = GB T/t = TB This patch changes -numa and -m input to use strtosz().

2010-10-30Add fprintf_function for function pointers to fprintf-like functionsStefan Weil

2010-10-23qemu-timer: move commonly used timer code to qemu-timer-commonBlue Swirl
Move timer init functions to a new file, qemu-timer-common.c. Make other critical timer functions inlined to preserve performance in qemu-timer.c, also move muldiv64() (used by the inline functions) to qemu-timer.h. Adjust block/raw-posix.c and simpletrace.c to use get_clock() directly. Remove a similar/duplicate definition in qemu-tool.c. Adjust hw/omap_clk.c to include qemu-timer.h because muldiv64() is used there. After this change, tracing can be used also for user code and simpletrace on Win32.

2010-10-22Remove special handling of system include files (no longer needed)Stefan Weil
The formerly used dyngen code did not work with system include files like stdio.h. Tests with Linux, OSX and Win32 show that this restriction is no longer needed. So we hopefully can remove that special piece of code. This results in cleaner code and allows better use of the new GCC_FMT_ATTR macro.

2010-10-03Replace most gcc format attributes by macro GCC_FMT_ATTR (format checking)Stefan Weil
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).

2010-09-22Move macros GCC_ATTR and GCC_FMT_ATTR to common header fileStefan Weil
By moving the definition of GCC_ATTR and GCC_FMT_ATTR from audio_int.h to qemu-common.h these macros are now generally available for further patches which add the gcc format attribute. Newer gcc versions support format gnu_printf which is better suited for use in QEMU than format printf (QEMU always uses standard format strings (even with mingw32)).

2010-06-15cow: stop using mmapChristoph Hellwig
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. And it fixes qemu-iotests testcase 012 which did not work properly due to issues with read-only mmap access. In addition we can also get rid of the now unused get_mmap_addr function.

2010-04-01notifier: event notifier implementationMichael S. Tsirkin
event notifiers are slightly generalized eventfd descriptors. Current implementation depends on eventfd because vhost is the only user, and vhost depends on eventfd anyway, but a stub is provided for non-eventfd case. We'll be able to further generalize this when another user comes along and we see how to best do this. Signed-off-by: Michael S.

2010-01-26block: avoid creating too large iovecs in multiwrite_mergeChristoph Hellwig
If we go over the maximum number of iovecs support by syscall we get back EINVAL from the kernel which translate to I/O errors for the guest. Add a MAX_IOV defintion for platforms that don't have it. For now we use the same 1024 define that's used on Linux and various other platforms, but until the windows block backend implements some kind of vectored I/O it doesn't matter.

2010-01-19Fix QEMU_WARN_UNUSED_RESULTKevin Wolf
Since commit 747bbdf7 QEMU_WARN_UNUSED_RESULT is never defined as it is conditional on a define from config-host.h which is included only later. Include that file earlier to get the warnings back. Reactivating it unfortunately leads to some warnings about unused qdev_init results. These calls are changed to qdev_init_nofail to avoid build failures.

2009-09-11block: use fdatasync instead of fsync if possibleChristoph Hellwig
If we are flushing the caches for our image files we only care about the data (including the metadata required for accessing it) but not things like timestamp updates. So try to use fdatasync instead of fsync to implement the flush operations. Unfortunately many operating systems still do not support fdatasync, so we add a qemu_fdatasync wrapper that uses fdatasync if available as per the _POSIX_SYNCHRONIZED_IO feature macro or fsync otherwise.

2009-09-11Add bdrv_aio_multiwriteKevin Wolf
One performance problem of qcow2 during the initial image growth are sequential writes that are not cluster aligned. In this case, when a first requests requires to allocate a new cluster but writes only to the first couple of sectors in that cluster, the rest of the cluster is zeroed - just to be overwritten by the following second request that fills up the cluster. Let's try to merge sequential write requests to the same cluster, so we can avoid to write the zero padding to the disk in the first place. As a nice side effect, also other formats take advantage of dealing with less and larger requests. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
