2011-07-30exec.h cleanupBlue Swirl1-142/+0
Move softmmu_exec.h include directives from target-*/exec.h to target-*/op_helper.c. Move also various other stuff only used in op_helper.c there. Define global env in dyngen-exec.h. For i386, move wrappers for segment and FPU helpers from user-exec.c to op_helper.c. Implement raise_exception_err_env() to handle dynamic CPUState. Move the function declarations to cpu.h since they can be used outside of op_helper.c context. LM32, s390x, UniCore32: remove unused cpu_halted(), regs_to_env() and env_to_regs(). ARM: make raise_exception() static. Convert #include "exec.h" to #include "cpu.h" #include "dyngen-exec.h" and remove now unused target-*/exec.h. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-06-26Move cpu_has_work and cpu_pc_from_tb to cpu.hBlue Swirl1-46/+0
Move functions cpu_has_work() and cpu_pc_from_tb() from exec.h to cpu.h. This is needed by later patches. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26exec.h: fix coding style and change cpu_has_work to return boolBlue Swirl1-1/+1
Before the next patch, fix coding style of the areas affected. Change the type of the return value from cpu_has_work() and qemu_cpu_has_work() to bool. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-06-26x86: use caller supplied CPUState for interrupt related stuffBlue Swirl1-10/+0
Several x86 specific functions are called from cpu-exec.c with the assumption that global env register is valid. This will be changed later, so make the functions use caller supplied CPUState parameter. It would be cleaner to move the functions to helper.c, but there are quite a lot of dependencies between do_interrupt() and other functions. Add helpers for svm_check_intercept() and cpu_cc_compute_all() instead of calling the helper (which uses global env, AREG0) directly. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2010-02-28target-i386: fix crash on x86 32bit linux host with hw breakpoint exceptionsJason Wessel1-0/+1
If you make use of hw breakpoints on a 32bit x86 linux host, qemu will segmentation fault when processing the exception. The problem is that the value of env is stored in $ebp in the op_helper raise_exception() function, and it can have the wrong value when calling it from non generated code. It is possible to work around the problem by restoring the value of env before calling raise_exception() using a new helper function that takes (CPUState *) as one of the arguments.

2009-06-22Handle init/sipi in a main cpu exec loop. (v2)Gleb Natapov1-0/+2
This should fix compilation problem in case of CONFIG_USER_ONLY. Currently INIT/SIPI is handled in the context of CPU that sends IPI. This patch changes this to handle them like all other events in a main cpu exec loop. When KVM will gain thread per vcpu capability it will be much more clear to handle those event by cpu thread itself and not modify one cpu's state from the context of the other.

2008-12-13x86 cleanupblueswir11-18/+1
Remove some unnecessary includes, add needed includes, move prototypes to cpu.h to suppress missing prototype warnings. Remove unused functions and prototypes (cpu_x86_flush_tlb, cpu_lock, cpu_unlock, restore_native_fp_state, save_native_fp_state). Make some functions and data static (f15rk, parity_table, rclw_table, rclb_table, raise_interrupt, fpu_raise_exception), they are not used outside op_helper.c anymore. Make some x86_64 and user only code conditional to avoid warnings.
