2010-11-04block: Allow bdrv_flush to return errorsKevin Wolf
This changes bdrv_flush to return 0 on success and -errno in case of failure. It's a requirement for implementing proper error handle in users of bdrv_flush. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
2010-11-04scsi-disk: Implement rerror optionKevin Wolf
This implements the rerror option for SCSI disks. It also includes minor changes to the write path where the same code is used that was criticized in the review for the changes to the read path required for rerror support.

2010-11-03Fold send_all() wrapper unix_write() into one functionJes Sorensen
The current send_all() wrapper for POSIX calls does nothing but call unix_write(). Merge them to simplify the code. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-11-03Remove obsolete 'f' double parameter typeJes Sorensen
'f' double is no longer used, and we should be using floating point variables to store byte sizes. Remove it. Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2010-11-03Switch migrate_set_speed() to take an 'o' argument rather than a float.Jes Sorensen
Clarify default value of MB in migration speed argument in monitor, if no suffix is specified. This differ from previous default of bytes, but is consistent with the rest of the places where we accept a size argument.

2010-11-03Add support for 'o' octet (bytes) format as monitor parameter.Jes Sorensen
Octet format relies on strtosz which supports K/k, M/m, G/g, T/t suffixes and unit support for humans, like 1.3G Signed-off-by: Jes Sorensen <Jes.Sorensen@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
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().

2010-11-01Add Intel HD Audio support to qemu.Gerd Hoffmann
This patch adds three devices to qemu: intel-hda Intel HD Audio Controller, the PCI device. Provides a HDA bus. Emulates ICH6 at the moment. Adding a ICH9 PCIE variant shouldn't be hard. hda-duplex HDA Codec. Attaches to the HDA bus. Supports 16bit stereo, rates 16k -> 96k, playback, recording and volume control (with CONFIG_MIXEMU=y). hda-output HDA Codec without recording support. Subset of the hda-duplex codec. Use this if you don't want your guests access your mic. Usage: add '-device intel-hda -device hda-duplex' to your command line. Tested guests: * Linux works. * Win7 works. * DOS (mpxplay) works. * WinXP doesn't work. [ v2 changes ] * Fixed endianess, big endian hosts work now. * Fixed some emulation bugs. * Added immediate command emulation. * Added vmstate support. * Make it behave like all other sound card drivers: - can be configured via '--audio-card-list=hda' - can be added to a VM using '-soundhw hda' * Code style fixups. * Zapped guest-triggerable asserts. * Handle partial reads/writes of audio data correctly.

fprintf_function uses format checking with GCC_FMT_ATTR. It is declared in qemu-common.h and used in cpu-all.h (which is included from cpu.h), so qemu-common.h must be included earlier.

2010-10-27pci: improve w1c mask handlingMichael S. Tsirkin
- save/restore must not check w1c bits since they are in fact guest controlled - clear w1c bits on reset Note: for express there are different kinds of reset, some leave part of config space alone.

2010-10-27pcie: clean up hot plug notificationMichael S. Tsirkin

2010-10-27qemu-options.def: add to generated header listMichael S. Tsirkin
All files include qemu-options.h which pulls in qemu-options.def from the root directory. Thus generating qemu-options.def from Makefile.objs under the target directory is not effective. Further, people expect .def file to get cleaned with make clean: it does not have state so no reason to defer removing it until distclean. Also add a rule to remove old files that might be around. This fixes the error: ‘QEMU_OPTION_spice’ undeclared (first use in this function) error that some people reported which is really down to an out of date .def file. Signed-off-by: Michael S.

2010-10-27net: properly handle illegal fd/vhostfd from command lineJason Wang

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.
