* cpu: move exec-all.h inclusion out of cpu.hPaolo Bonzini2016-05-196-1/+5
| | | | | | | | | | exec-all.h contains TCG-specific definitions. It is not needed outside TCG-specific files such as translate.c, exec.c or *helper.c. One generic function had snuck into include/exec/exec-all.h; move it to include/qom/cpu.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* target-unicore32: make cpu-qom.h not target specificPaolo Bonzini2016-05-192-29/+31
| | | | | | | | | Make UniCore32CPU an opaque type within cpu-qom.h, and move all definitions of private methods, as well as all type definitions that require knowledge of the layout to cpu.h. This helps making files independent of NEED_CPU_H if they only need to pass around CPU pointers. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* cpu: make cpu-qom.h only include-able from cpu.hPaolo Bonzini2016-05-191-1/+0Star
| | | | | | | | | | | | Make cpu-qom.h so that it is only included from cpu.h. Then there is no need for it to include cpu.h again. Later we will make cpu-qom.h target independent and we will _want_ to include it from elsewhere, but for now reduce the number of cases to handle.

* tcg: Allow goto_tb to any target PC in user modeSergey Fedorov2016-05-131-5/+11
| | | | | | | | | | | | | | In user mode, there's only a static address translation, TBs are always invalidated properly and direct jumps are reset when mapping change. Thus the destination address is always valid for direct jumps and there's no need to restrict it to the pages the TB resides in.

* tb: consistently use uint32_t for tb->flagsEmilio G. Cota2016-05-131-1/+1
| | | | | | | | | | | | | | | | | | We are inconsistent with the type of tb->flags: usage varies loosely between int and uint64_t. Settle to uint32_t everywhere, which is superior to both: at least one target (aarch64) uses the most significant bit in the u32, and uint64_t is wasteful. Compile-tested for all targets.

* include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster2016-03-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* tcg: Add type for vCPU pointersLluís Vilanova2016-03-011-1/+1
| | | | | | | | | | | | | | | | | | | | Adds the 'TCGv_env' type for pointers to 'CPUArchState' objects. The tracing infrastructure later needs to differentiate between regular pointers and pointers to vCPUs. Also changes all targets to use the new 'TCGv_env' type instead of the generic 'TCGv_ptr'. As of now, the change is merely cosmetic ('TCGv_env' translates into 'TCGv_ptr'), but that could change in the future to enforce the difference. Note that a 'TCGv_env' type (for 'CPUState') is not added, since all helpers currently receive the architecture-specific pointer ('CPUArchState').

* qdev: Protect device-list-properties against broken devicesMarkus Armbruster2015-10-091-0/+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.

* target-unicore: Remove unused functionsPeter Maydell2014-06-242-50/+0Star
| | | | | | | | The functions gen_st64, gen_ld64, gen_mulxy, ucf64_itod and ucf64_dtoi are all unused; remove them. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
* softmmu: introduce cpu_ldst.hPaolo Bonzini2014-06-052-2/+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.

* softmmu: commonize helper definitionsPaolo Bonzini2014-06-051-14/+0Star
| | | | | | | | | 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>
* tcg: Invert the inclusion of helper.hRichard Henderson2014-05-285-9/+5Star
| | | | | | | | | | 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>

* cpu: Move breakpoints field from CPU_COMMON to CPUStateAndreas Färber2014-03-131-2/+2
| | | | | | | | 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>

* cpu: Turn cpu_handle_mmu_fault() into a CPUClass hookAndreas Färber2014-03-135-8/+15
| | | | | | | | Note that while such functions may exist both for *-user and softmmu, only *-user uses the CPUState hook, while softmmu reuses the prototype for calling it directly. Signed-off-by: Andreas Färber <afaerber@suse.de>
* cpu: Factor out cpu_generic_init()Andreas Färber2014-03-131-10/+3Star
