2016-12-20Move target-* CPU file into a target/ folderThomas Huth
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

2016-11-01log: Add locking to large logging blocksRichard Henderson
Reuse the existing locking provided by stdio to keep in_asm, cpu, op, op_opt, op_ind, and out_asm as contiguous blocks. While it isn't possible to interleave e.g. in_asm or op_opt logs because of the TB lock protecting all code generation, it is possible to interleave cpu logs, or to interleave a cpu dump with an out_asm dump. For mingw32, we appear to have no viable solution for this. The locking functions are not properly exported from the system runtime library.

2016-06-20exec: [tcg] Track which vCPU is performing translation and executionLluís Vilanova
Information is tracked inside the TCGContext structure, and later used by tracing events with the 'tcg' and 'vcpu' properties. The 'cpu' field is used to check tracing of translation-time events ("*_trans"). The 'tcg_env' field is used to pass it to execution-time events ("*_exec").

2016-05-12tcg: Allow goto_tb to any target PC in user modeSergey Fedorov
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.

2016-03-01tcg: Add type for vCPU pointersLluís Vilanova
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').

2015-09-11tlb: Add "ifetch" argument to cpu_mmu_index()Benjamin Herrenschmidt
This is set to true when the index is for an instruction fetch translation. The core get_page_addr_code() sets it, as do the SOFTMMU_CODE_ACCESS acessors. All targets ignore it for now, and all other callers pass "false". This will allow targets who wish to split the mmu index between instruction and data accesses to do so. A subsequent patch will do just that for PowerPC.
