2023-10-04tcg: Split out tcg init functions to tcg/startup.hRichard Henderson
The tcg/tcg.h header is a big bucket, containing stuff related to the translators and the JIT backend. The places that initialize tcg or create new threads do not need all of that, so split out these three functions to a new header.

2023-10-04accel/tcg: Make cpu-exec-common.c a target agnostic unitPhilippe Mathieu-Daudé
cpu_in_serial_context() is not target specific, move it declaration to "internal-common.h" (which we include in the 4 source files modified). Remove the unused "exec/exec-all.h" header from cpu-exec-common.c. There is no more target specific code in this file: make it target agnostic.

A large chunk of ld/st functions are moved from cputlb.c and user-exec.c to ldst_common.c.inc as their implementation is the same between both modes. Eventually, ldst_common.c.inc could be compiled into a separate target-specific compilation unit, and be linked in with the targets.

Push computation down into the if statements to the point the data is used. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-09-16plugin: Simplify struct qemu_plugin_hwaddrRichard Henderson
Rather than saving MemoryRegionSection and offset, save phys_addr and MemoryRegion. This matches up much closer with the plugin api. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-09-16accel/tcg: Use CPUTLBEntryFull.phys_addr in io_failedRichard Henderson
Since the introduction of CPUTLBEntryFull, we can recover the full cpu address space physical address without having to examine the MemoryRegionSection. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-09-16accel/tcg: Split out io_prepare and io_failedRichard Henderson
These are common code from io_readx and io_writex. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2023-09-16accel/tcg: Simplify tlb_plugin_lookupRichard Henderson
Now that we defer address space update and tlb_flush until the next async_run_on_cpu, the plugin run at the end of the instruction no longer has to contend with a flushed tlb. Therefore, delete SavedIOTLB entirely. Properly return false from tlb_plugin_lookup when we do not have a tlb match. Fixes a bug in which SavedIOTLB had stale data, because there were multiple i/o accesses within a single insn. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
