2015-10-09qdev: Protect device-list-properties against broken devicesMarkus Armbruster1-0/+7
Several devices don't survive object_unref(object_new(T)): they crash or hang during cleanup, or they leave dangling pointers behind. This breaks at least device-list-properties, because qmp_device_list_properties() needs to create a device to find its properties. Broken in commit f4eb32b "qmp: show QOM properties in device-list-properties", v2.1. Example reproducer: $ qemu-system-aarch64 -nodefaults -display none -machine none -S -qmp stdio {"QMP": {"version": {"qemu": {"micro": 50, "minor": 4, "major": 2}, "package": ""}, "capabilities": []}} { "execute": "qmp_capabilities" } {"return": {}} { "execute": "device-list-properties", "arguments": { "typename": "pxa2xx-pcmcia" } } qemu-system-aarch64: /home/armbru/work/qemu/memory.c:1307: memory_region_finalize: Assertion `((&mr->subregions)->tqh_first == ((void *)0))' failed. Aborted (core dumped) [Exit 134 (SIGABRT)] Unfortunately, I can't fix the problems in these devices right now. Instead, add DeviceClass member cannot_destroy_with_object_finalize_yet to mark them: * Hang during cleanup (didn't debug, so I can't say why): "realview_pci", "versatile_pci". * Dangling pointer in cpus: most CPUs, plus "allwinner-a10", "digic", "fsl,imx25", "fsl,imx31", "xlnx,zynqmp", because they create such CPUs * Assert kvm_enabled(): "host-x86_64-cpu", host-i386-cpu", "host-powerpc64-cpu", "host-embedded-powerpc-cpu", "host-powerpc-cpu" (the powerpc ones can't currently reach the assertion, because the CPUs are only registered when KVM is enabled, but the assertion is arguably in the wrong place all the same) Make qmp_device_list_properties() fail cleanly when the device is so marked. This improves device-list-properties from "crashes, hangs or leaves dangling pointers behind" to "fails". Not a complete fix, just a better-than-nothing work-around. In the above reproducer, device-list-properties now fails with "Can't list properties of device 'pxa2xx-pcmcia'". This also protects -device FOO,help, which uses the same machinery since commit ef52358 "qdev-monitor: include QOM properties in -device FOO, help output", v2.2.

With the new enumeration logic, cpu_exec_init() can fail if cpu_index values corresponding to max_cpus have already been handed out.

2015-06-22m68k: fix usp processing on interrupt entry and exception exitGreg Ungerer1-4/+3
The action to potentially switch sp register is not occurring at the correct point in the interrupt entry or exception exit sequences. For the interrupt entry case the sp on entry is used to create the stack exception frame - but this may well be the user stack pointer, since we haven't done the switch yet. Re-order the flow to switch the sp regs then use the current sp to create the exception frame. For the return from exception case the code is unwinding the sp after switching sp registers. But it should always unwind the supervisor sp first, then carry out any required sp switch. Note that these problems don't effect operation unless the user sp bit is set in the CACR register. Only a single sp is used in the default power up state. Previously Linux only used this single sp mode. But modern versions of Linux use the user sp mode now, so we need correct behavior for Linux to work.

2014-06-05softmmu: introduce cpu_ldst.hPaolo Bonzini2-2/+2
This will collect all load and store helpers soon. For now it is just a replacement for softmmu_exec.h, which this patch stops including directly, but we also include it where this will be necessary in order to simplify the next patch.

2014-06-05softmmu: commonize helper definitionsPaolo Bonzini1-14/+0
They do not need to be in op_helper.c. Because cputlb.c now includes softmmu_template.h twice for each size, io_readX must be elided the second time through. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-05-28tcg: Invert the inclusion of helper.hRichard Henderson4-9/+4
Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

2014-03-13cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber3-3/+4
Most targets were using offsetof(CPUFooState, breakpoints) to determine how much of CPUFooState to clear on reset. Use the next field after CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise. Signed-off-by: Andreas Färber <afaerber@suse.de>
