* audio: Replace static functions in header file by macros, remove GCC_ATTRStefan Weil2013-06-211-3/+0
| | | | | | | | | | | Using macros instead of static functions for dolog and for ldebug simplifies the code and can also reduce the total code size. GCC_ATTR was only used in audio_int.h, so it is now unused and the definition can be removed from compiler.h.

* memory: make section size a 128-bit integerPaolo Bonzini2013-06-201-0/+19
| | | | | | | | | | | So far, the size of all regions passed to listeners could fit in 64 bits, because artificial regions (containers and aliases) are eliminated by the memory core, leaving only device regions which have reasonable sizes An IOMMU however cannot be eliminated by the memory core, and may have an artificial size, hence we may need 65 bits to represent its size.

* win32: add readv/writev emulationPaolo Bonzini2013-04-291-0/+17
| | | | | | | | | | | | | | | 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).

* nbd: Keep hostname and port separateKevin Wolf2013-03-221-0/+1
| | | | | | | | | | | | | | | The NBD block supports an URL syntax, for which a URL parser returns separate hostname and port fields. It also supports the traditional qemu syntax encoded in a filename. Until now, after parsing the URL to get each piece of information, a new string is built to be fed to socket functions. Instead of building a string in the URL case that is immediately parsed again, parse the string in both cases and use the QemuOpts interface to qemu-sockets.c.

* Add a TPM Passthrough backend driver implementationStefan Berger2013-03-121-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based of off version 9 of Stefan Berger's patch series "QEMU Trusted Platform Module (TPM) integration" and adds a new backend driver for it. This patch adds a passthrough backend driver for passing commands sent to the emulated TPM device directly to a TPM device opened on the host machine. Thus it is possible to use a hardware TPM device in a system running on QEMU, providing the ability to access a TPM in a special state (e.g. after a Trusted Boot). This functionality is being used in the acTvSM Trusted Virtualization Platform which is available on [1]. Usage example: qemu-system-x86_64 -tpmdev passthrough,id=tpm0,path=/dev/tpm0 \ -device tpm-tis,tpmdev=tpm0 \ -cdrom test.iso -boot d Some notes about the host TPM: The TPM needs to be enabled and activated. If that's not the case one has to go through the BIOS/UEFI and enable and activate that TPM for TPM commands to work as expected. It may be necessary to boot the kernel using tpm_tis.force=1 in the boot command line or 'modprobe tpm_tis force=1' in case of using it as a module.

* qemu-log: default to stderr for logging outputPeter Maydell2013-02-261-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.

| | | | | | | | | | | | | | | | | Remove the function qemu_log_try_set_file() and its users (which are all in TCG code generation functions for various targets). This function was added to abstract out code which was originally written as "if (!logfile) logfile = stderr;" in order that BUG: case code which did an unguarded "fprintf(logfile, ...)" would not crash if debug logging was not enabled. Since those direct uses of logfile have also been abstracted away into qemu_log() calls which check for a NULL logfile, there is no need for the target-* files to mess with the user's chosen logging settings.
