2023-06-05tcg: Split helper-gen.hRichard Henderson
Create helper-gen-common.h without the target specific portion. Use that in tcg-op-common.h. Reorg headers in target/arm to ensure that helper-gen.h is included before helper-info.c.inc. All other targets are already correct in this regard. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

Make tcg_gen_callN a static function. Create tcg_gen_call[0-7] functions for use by helper-gen.h.inc. Removes a multiplicty of calls to __stack_chk_fail, saving up to 143kiB of .text space as measured on an x86_64 host.

2023-06-05tcg: Pass TCGHelperInfo to tcg_gen_callNRichard Henderson
In preparation for compiling tcg/ only once, eliminate the all_helpers array. Instantiate the info structs for the generic helpers in accel/tcg/, and the structs for the target-specific helpers in each translate.c. Since we don't see all of the info structs at startup, initialize at first use, using g_once_init_* to make sure we don't race while doing so.

2023-06-05tcg: Widen CPUTLBEntry comparators to 64-bitsRichard Henderson
This makes CPUTLBEntry agnostic to the address size of the guest. When 32-bit addresses are in effect, we can simply read the low 32 bits of the 64-bit field. Similarly when we need to update the field for setting TLB_NOTDIRTY. For TCG backends that could in theory be big-endian, but in practice are not (arm, loongarch, riscv), use QEMU_BUILD_BUG_ON to document and ensure this is not accidentally missed. For s390x, which is always big-endian, use HOST_BIG_ENDIAN anyway, to document the reason for the adjustment. For sparc64 and ppc64, always perform a 64-bit load, and rely on the following 32-bit comparison to ignore the high bits. Rearrange mips and ppc if ladders for clarity.

In particular, it's useful to map guest memory directly into /dev/mem for experimentation. To make this work consistently, also fix up all places in QEMU that expect fd offsets to be 0.

2023-05-18migration: Add last stage indicator to global dirty logGavin Shan
The global dirty log synchronization is used when KVM and dirty ring are enabled. There is a particularity for ARM64 where the backup bitmap is used to track dirty pages in non-running-vcpu situations. It means the dirty ring works with the combination of ring buffer and backup bitmap. The dirty bits in the backup bitmap needs to collected in the last stage of live migration. In order to identify the last stage of live migration and pass it down, an extra parameter is added to the relevant functions and callbacks. This last stage indicator isn't used until the dirty ring is enabled in the subsequent patches. No functional change intended.

2023-05-16include/exec/memop: Add MO_ATOM_*Richard Henderson
This field may be used to describe the precise atomicity requirements of the guest, which may then be used to constrain the methods by which it may be emulated by the host. For instance, the AArch64 LDP (32-bit) instruction changes semantics with ARMv8.4 LSE2, from MO_64 | MO_ATOM_IFALIGN_PAIR (64-bits, single-copy atomic only on 4 byte units, nonatomic if not aligned by 4), to MO_64 | MO_ATOM_WITHIN16 (64-bits, single-copy atomic within a 16 byte block) The former may be implemented with two 4 byte loads, or a single 8 byte load if that happens to be efficient on the host. The latter may not be implemented with two 4 byte loads and may also require a helper when misaligned.

2023-05-02accel/tcg: Use one_insn_per_tb global instead of old singlestep globalPeter Maydell

Replace the old global with a new 'one_insn_per_tb' which is defined in tcg-all.c and declared in accel/tcg/internal.h. This keeps it restricted to the TCG code, unlike 'singlestep' which was available to every file in the system and defined in multiple different places for softmmu vs linux-user vs bsd-user. While we're making this change, use qatomic_read() and qatomic_set() on the accesses to the new global, because TCG will read it without holding a lock.

Add a flag to the DeviceState, when a device is engaged in PIO/MMIO/DMA. This flag is set/checked prior to calling a device's MemoryRegion handlers, and set when device code initiates DMA. The purpose of this flag is to prevent two types of DMA-based reentrancy issues: 1.) mmio -> dma -> mmio case 2.) bh -> dma write -> mmio case These issues have led to problems such as stack-exhaustion and use-after-frees.
