2014-03-13cputlb: Change tlb_flush() argument to CPUStateAndreas Färber
Signed-off-by: Andreas Färber <afaerber@suse.de>
2014-03-13cpu: Turn cpu_handle_mmu_fault() into a CPUClass hookAndreas Färber
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>
2014-03-13cpu: Turn cpu_has_work() into a CPUClass hookAndreas Färber
Default to false. Tidy variable naming and inline cast uses while at it. Tested-by: Jia Liu <proljc@gmail.com> (or32) Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-29cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"Andreas Färber
Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code. This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed". The reason for the failure is that CPUClass::kvm_fd is not yet initialized in the following call graph: ->x86_cpu_realizefn ->x86_cpu_apic_realize ->qdev_init ->device_set_realized ->device_reset (hotplugged == 1) ->apic_reset_common ->vapic_base_update ->kvm_apic_vapic_base_update This causes attempted KVM vCPU ioctls to fail. By contrast, in the non-hotplug case the APIC is reset much later, when the vCPU is already initialized. As a quick and safe solution, move the qemu_init_vcpu() call back into the targets' realize functions.

2013-07-23cpu: Turn cpu_get_phys_page_debug() into a CPUClass hookAndreas Färber
Change breakpoint_invalidate() argument to CPUState alongside. Since all targets now assign a softmmu-only field, we can drop helpers cpu_class_set_{do_unassigned_access,vmsd}() and device_class_set_vmsd(). Prepares for changing cpu_memory_rw_debug() argument to CPUState. Acked-by: Max Filippov <jcmvbkbc@gmail.com> (for xtensa) Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-07-23target-unicore32: Implement CPUClass::set_pc()Andreas Färber
This adds support for GDB's c addr (Continue) and s addr (Single Step). Prepares for dropping cpu_pc_from_tb(). Signed-off-by: Andreas Färber <afaerber@suse.de>
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: Turn cpu_dump_{state,statistics}() into CPUState hooksAndreas Färber
Make cpustats monitor command available unconditionally. Prepares for changing kvm_handle_internal_error() and kvm_cpu_exec() arguments to CPUState. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12cpu: Replace do_interrupt() by CPUClass::do_interrupt methodAndreas Färber
This removes a global per-target function and thus takes us one step closer to compiling multiple targets into one executable. It will also allow to override the interrupt handling for certain CPU families. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-16cpu: Add CPUArchState pointer to CPUStateAndreas Färber
The target-specific ENV_GET_CPU() macros have allowed us to navigate from CPUArchState to CPUState. The reverse direction was not supported. Avoid introducing CPU_GET_ENV() macros by initializing an untyped pointer that is initialized in derived instance_init functions. The field may not be called "env" due to it being poisoned.

2013-02-16target-unicore32: Move TCG initialization to UniCore32CPU initfnAndreas Färber
Normalize the "inited" logic and add a tcg_enabled() check to suppress it for qtest. Ensures that a QOM-created UniCore32CPU is usable. Acked-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-16target-unicore32: Introduce QOM realizefn for UniCore32CPUAndreas Färber
Introduce a realizefn and set realized = true in uc32_cpu_init(). Acked-by: Guan Xuetao <gxt@mprc.pku.edu.cn> [AF: Invoke the parent's realizefn] Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-01target-unicore32: Rename CPU subtypesAndreas Färber
In the initial conversion of CPU models to QOM types, model names were mapped 1:1 to type names. As a side effect this gained us a type "any", which is now a device. To avoid "-device any" silliness and to pave the way for compiling multiple targets into one executable, adopt a <name>-<arch>-cpu scheme. No functional changes for -cpu arguments.

2013-02-01target-unicore32: Mark as unmigratableAndreas Färber
CPU_SAVE_VERSION 2 was bogus as both save and load would just throw a hw_error(). Therefore we can without problems suppress registration of "cpu_common" VMState by dropping CPU_SAVE_VERSION define and provide an unmigratable "cpu" VMStateDescription for UniCore32CPU at device level instead, where we can attach this the QOM way.

2013-01-28target-unicore32: Use type_register() instead of type_register_static()Andreas Färber
According to its documentation, type_register_static()'s TypeInfo argument should exist for the life type of the type. Therefore use type_register() when registering the list of CPU subtypes. No functional change with the current implementation. Cf. 918fd0839eeafc83bd4984364321a947d29041fe for arm. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-28target-unicore32: Catch attempt to instantiate abstract type in cpu_init()Andreas Färber
Fixes -cpu unicore32-cpu asserting. Cc: qemu-stable@nongnu.org Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-01-27target-unicore32: Detect attempt to instantiate non-CPU type in cpu_init()Andreas Färber
Consolidate model checking into a new uc32_cpu_class_by_name(). If the name matches an existing type, also check whether that type is actually (a sub-type of) TYPE_UNICORE32_CPU. This fixes, e.g., -cpu puv3_dma asserting. Cc: qemu-stable@nongnu.org Signed-off-by: Andreas Färber <afaerber@suse.de>
2012-10-31cpus: Pass CPUState to [qemu_]cpu_has_work()Andreas Färber
For target-mips also change the return type to bool. Make include paths for cpu-qom.h consistent for alpha and unicore32. Signed-off-by: Andreas Färber <afaerber@suse.de> [AF: Updated new target-openrisc function accordingly] Acked-by: Richard Henderson <rth@twiddle.net> (for alpha)
2012-08-11unicore32-softmmu: Make UniCore32 cpuid & exceptions correct and runableGuan Xuetao
This patch initializes the cpuid to exactly correct value because linux kernel will check it. In addition, the exception types are specified in proper situations. Then it could make exceptions generated correctly and timely. Signed-off-by: Guan Xuetao <gxt@mprc.pku.edu.cn> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
