2013-06-28cpu: Change qemu_init_vcpu() argument to CPUStateAndreas Färber
This allows to move the call into CPUState's realizefn. Therefore move the stub into libqemustub.a. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-06-28cpu: Guard cpu_{save,load}() definitionsAndreas Färber
A few targets already managed to implement cpu_save() and cpu_load() without defining CPU_SAVE_VERSION that causes them to be registered. Guard the prototypes with CPU_SAVE_VERSION to avoid this happening again until all targets are converted to VMState (or QIDL).

2013-06-14create qemu_openpty_raw() helper function and move it to a separate fileMichael Tokarev
In two places qemu uses openpty() which is very system-dependent, and in both places the pty is switched to raw mode as well. Make a wrapper function which does both steps, and move all the system-dependent complexity into a separate file, together with static/local implementations of openpty() and cfmakeraw() from qemu-char.c. It is in a separate file, not part of oslib-posix.c, because openpty() often resides in -lutil which is not linked to every program qemu builds. This change removes #including of <pty.h>, <termios.h> and other rather specific system headers out of qemu-common.h, which isn't a place for such specific headers really. This version has been verified to build correctly on Linux, OpenBSD, FreeBSD and OpenIndiana. On the latter it lets qemu to be built with gtk gui which were not possible there due to missing openpty() and cfmakeraw().

2013-04-29win32: add readv/writev emulationPaolo Bonzini
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).

2013-04-24ccid-card-passthru, dev-smartcard-reader: add debug environment variablesAlon Levy
Introduces a new utility function: parse_debug_env to avoid code duplication. This overrides whatever debug value is set on the corresponding devices from the command line, and is meant to ease the usage with any management stack. For libvirt you can set environment variables by extending the dom namespace, i.e: <domain type='kvm' id='3' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'> <qemu:commandline> <qemu:env name='QEMU_CCID_PASSTHRU_DEBUG' value='4'/> <qemu:env name='QEMU_CCID_DEBUG' value='4'/> </qemu:commandline> </domain> Signed-off-by: Alon Levy <alevy@redhat.com> Reviewed-by: Marc-André Lureau <mlureau@redhat.com>

2013-03-26cutils: add a function to find non-zero content in a bufferPeter Lieven
this adds buffer_find_nonzero_offset() which is a SSE2/Altivec optimized function that searches for non-zero content in a buffer. the function starts full unrolling only after the first few chunks have been checked one by one. analyzing real memory page data has revealed that non-zero pages are non-zero within the first 256-512 bits in most cases. as this function is also heavily used to check for zero memory pages this tweak has been made to avoid the high setup costs of the fully unrolled check for non-zero pages. due to the optimizations used in the function there are restrictions on buffer address and search length. the function can_use_buffer_find_nonzero_content() can be used to check if the function can be used safely.

Older glib doesn't implement g_poll(). Most notably the glib version in use on SLE11 is on 2.18 which is hit by this. We do want to use g_poll() in the source however. So on older systems, just wrap it with functions that do exist on older versions.

2013-02-04cutils: unsigned int parsing functionsEduardo Habkost
There are lots of duplicate parsing code using strto*() in QEMU, and most of that code is broken in one way or another. Even the visitors code have duplicate integer parsing code[1]. This introduces functions to help parsing unsigned int values: parse_uint() and parse_uint_full(). Parsing functions for signed ints and floats will be submitted later. parse_uint_full() has all the checks made by opts_type_uint64() at opts-visitor.c: - Check for NULL (returns -EINVAL) - Check for negative numbers (returns -EINVAL) - Check for empty string (returns -EINVAL) - Check for overflow or other errno values set by strtoll() (returns -errno) - Check for end of string (reject invalid characters after number) (returns -EINVAL) parse_uint() does everything above except checking for the end of the string, so callers can continue parsing the remainder of string after the number. Unit tests included. [1] string-input-visitor.c:parse_int() could use the same parsing code used by opts-visitor.c:opts_type_int(), instead of duplicating that logic.

2013-01-02iov: add qemu_iovec_concat_iov()Stefan Hajnoczi
The qemu_iovec_concat() function copies a subset of a QEMUIOVector. The new qemu_iovec_concat_iov() function does the same for a iov/cnt pair. It is easy to define qemu_iovec_concat() in terms of qemu_iovec_concat_iov(). The existing code is mostly unchanged, except for the assertion src->size >= soffset, which cannot be efficiently checked upfront on a iov/cnt pair. Instead we assert upon hitting the end of src with an unsatisfied soffset. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
