2012-03-24target-alpha: Make use of fp_status.flush_inputs_to_zero.Richard Henderson5-50/+26
This softfp feature post-dates the last major update to the Alpha fpu translation. We can make use of this to eliminate at least one helper function that was performing this operation by hand. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2012-03-24target-alpha: Move memory helpers to mem_helper.c.Richard Henderson3-37/+26
This completes the transition away from AREG0. This patch must be last because it requires CONFIG_TCG_PASS_AREG0 set too. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-10-08target-alpha: Add high-resolution access to wall clock and an alarm.Richard Henderson4-4/+48
The alarm is a fully general one-shot time comparator, which will be usable under Linux as a hrtimer source. It's much more flexible than the RTC source available on real hardware. The wall clock allows the guest access to the host timekeeping. Much like the KVM wall clock source for other guests. Both are accessed via the PALcode Cserve entry point.

2011-08-07Remove unused is_softmmu parameter from cpu_handle_mmu_faultBlue Swirl3-4/+4
Parameter is_softmmu (and its evil mutant twin brother is_softmuu) is not used in cpu_*_handle_mmu_fault() functions, remove them and adjust callers. Acked-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-30exec.h cleanupBlue Swirl2-40/+6
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>
2011-07-20Fix unassigned memory access handlingBlue Swirl2-4/+7
cea5f9a28faa528b6b1b117c9ab2d8828f473fef exposed bugs in unassigned memory access handling. Fix them by always passing CPUState to the handlers. Reported-by: Hervé Poussineau <hpoussin@reactos.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
2011-07-12target-alpha, target-ppc: Remove unnecessary setjmp.h includePeter Maydell1-2/+0
Remove the include of setjmp.h from the cpu.h of target-alpha and target-ppc. This is unnecessary because cpu-defs.h already includes this header; this change brings these two targets into line with all the rest. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2011-06-26Move cpu_has_work and cpu_pc_from_tb to cpu.hBlue Swirl2-20/+22
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

2011-05-31target-alpha: Use a fixed frequency for the RPCC in system mode.Richard Henderson1-1/+10

2011-05-31target-alpha: Implement cpu_alpha_handle_mmu_fault for system mode.Richard Henderson2-4/+138

2011-05-31target-alpha: Implement more CALL_PAL values inline.Richard Henderson1-32/+108
In particular, SWPIPL is used quite a lot by the Linux kernel. Doing this inline makes it significantly easier to step through without the debugger getting confused by the mode switch. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Disable interrupts properly.Richard Henderson2-1/+16
Interrupts are disabled in PALmode, and when the PS IL is high enough. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: All ISA checks to use TB->FLAGS.Richard Henderson2-181/+229

2011-05-31target-alpha: Use do_restore_state for arithmetic exceptions.Richard Henderson1-19/+30
This gets the PC right after an arithmetic exception. Also tidies the code in the TLB fault handlers to use common code. Signed-off-by: Richard Henderson <rth@twiddle.net>
