2012-03-30pl031: switch clock base to rtc_clockPaolo Bonzini
This lets the user specify the desired semantics. By default, the RTC will follow adjustments from the host's NTP client, and will remain in sync when the virtual machine is stopped. The previous behavior, which provides determinism with both icount and qtest, remains available with "-rtc clock=vm". pl031 supports migration, so we need to convert the time base from rtc_clock to vm_clock and back for backwards compatibility. (The rtc_clock may not be synchronized on the two machines, especially with savevm/loadvm, so the conversion is needed anyway. And since any time base will do, why not pick the one base that is backwards compatible). Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2012-03-30arm: switch real-time clocks to rtc_clockPaolo Bonzini
This lets the user specify the desired semantics. By default, the RTC will follow adjustments from the host's NTP client. "-rtc clock=vm" will improve determinism with both icount and qtest. Finally, the previous behavior is available with "-rtc clock=rt". Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
2012-03-30omap: switch omap_lpg to vm_clockPaolo Bonzini
The output of the pulse generator needs to be deterministic when running in -icount mode, and to remain constant whenever the VM is stopped. So the right clock to use is vm_clock. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2012-03-30ARM: Permit any ARMv6K CPU to read the MVFR0 and MVFR1 VFP registers.Andrew Towers
This patch replaces the ARM_FEATURE_VFP3 test when reading MVFR registers with a test for a new feature flag ARM_FEATURE_MVFR, and sets this feature for all ARMv6K cores (ARM1156 is not a v6K core, yet supports MVFR; qemu does not support ARM1156 at this time.) MVFR0 and MVFR1 were introduced in ARM1136JF-S r1p0 (ARMv6K, VFPv2) and are present in ARM1156T2F-S (non-v6K), ARM1176JZF-S, ARM11MPCore and newer cores. Reference: ARM DDI 0211H, 0290G, 0301H, 0360E. http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0211h/Ffbefjag.html Without this change, the linux kernel will not boot with VFP support enabled under ARM1176 system emulation, due to the unconditional use of MVFR1 at the end of vfp_init() in arch/arm/vfp/vfpmodule.c: VFP support v0.3: implemetor 41 architecture 1 part 20 variant b rev 5 Internal error: Oops - undefined instruction: 0 [#1] Signed-off-by: Andrew Towers <atowers@gmail.com> Reviewed-by: Andreas Färber <afaerber@suse.de> Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

2012-03-27qapi: add strict mode to input visitorPaolo Bonzini
While QMP in general is designed so that it is possible to ignore unknown arguments, in the case of the QMP server it is better to reject them to detect bad clients. In fact, we're already doing this at the top level in the argument checker. To extend this to complex structures, add a mode to the input visitor where it checks for unvisited keys and raises an error if it finds one.

2012-03-27qapi: place outermost object on qiv stackPaolo Bonzini
This is a slight change in the implementation of QMPInputVisitor that helps when adding strict mode. Const QObjects cannot be inc/decref-ed, and that's why QMPInputVisitor relies heavily on weak references to inner objects. I'm not removing the weak references now, but since refcount+const is a lost battle in C (C++ has "mutable") I think removing const is fine in this case.

2012-03-27qapi: untangle next_listPaolo Bonzini
Right now, the semantics of next_list are complicated. The caller must: * call start_list * call next_list for each element *including the first* * on the first call to next_list, the second argument should point to NULL and the result is the head of the list. On subsequent calls, the second argument should point to the last node (last result of next_list) and next_list itself tacks the element at the tail of the list. This works for both input and output visitor, but having the visitor write memory when it is only reading the list is ugly. Plus, relying on *list to detect the first call is tricky and undocumented. We can initialize so->entry in next_list instead of start_list, leaving it NULL in start_list. This way next_list sees clearly whether it is on the first call---as a bonus, it discriminates the cases based on internal state of the visitor rather than external state. We can also pull the assignment of the list head from generated code up to next_list.

2012-03-27qapi: allow freeing partially-allocated objectsPaolo Bonzini
Objects going through the dealloc visitor can be only partially allocated. Detect the situation and avoid a segfault. This also helps with the input visitor, when there are errors.

2012-03-27qapi: fix double free in qmp_output_visitor_cleanup()Laszlo Ersek
Stack entries in QmpOutputVisitor are navigation links (weak references), except the bottom (ie. least recently added) entry, which owns the root QObject [1]. Make qmp_output_visitor_cleanup() drop the stack entries, then release the QObject tree by the root. Attempting to serialize an invalid enum inside a dictionary is an example for triggering the double free.
