2013-07-09target-alpha: Change gen_intermediate_code_internal() argument to AlphaCPUAndreas Färber
Also use bool argument while at it. Prepares for moving singlestep_enabled field to CPUState. Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-03gen-icount.h: Rename gen_icount_start/end to gen_tb_start/endPeter Maydell
The gen_icount_start/end functions are now somewhat misnamed since they are useful for generic "start/end of TB" code, used for more than just icount. Rename them to gen_tb_start/end.

2013-01-15cpu: Move cpu_index field to CPUStateAndreas Färber
Note that target-alpha accesses this field from TCG, now using a negative offset. Therefore the field is placed last in CPUState. Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change. Move common parts of mips cpu_state_reset() to mips_cpu_reset().

2012-12-19target-alpha: Turn CPU definitions into subclassesAndreas Färber
Make TYPE_ALPHA_CPU abstract and add types <name>-alpha-cpu. Use type inheritence, and turn "2*" models into aliases. Move cpu_alpha_init() to cpu.c and split out CPU realization.

2011-10-08target-alpha: Add high-resolution access to wall clock and an alarm.Richard Henderson
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.

2011-05-31target-alpha: Implement more CALL_PAL values inline.Richard Henderson
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: All ISA checks to use TB->FLAGS.Richard Henderson

2011-05-31target-alpha: Add IPRs to be used by the emulation PALcode.Richard Henderson

2011-05-31target-alpha: Tidy exception constants.Richard Henderson
There's no need to attempt to match EXCP_* values with PALcode entry point offsets. Instead, compress all the values to make for more efficient switch statements within QEMU. We will be doing TLB fill within QEMU proper, not within the PALcode, so all of the ITB/DTB miss, double fault, and access exceptions can be compressed to EXCP_MMFAULT. Compress all of the EXCP_CALL_PAL exceptions into one. Use env->error_code to store the specific entry point. Signed-off-by: Richard Henderson <rth@twiddle.net>
2011-05-31target-alpha: Rationalize internal processor registers.Richard Henderson
Delete all the code that tried to emulate the real IPRs of some unnamed CPU. Replace those with just 3 slots that we can use to communicate trap information between the helper functions that signal exceptions and the OS trap handler. Signed-off-by: Richard Henderson <rth@twiddle.net>
