| | | | | | | | | | | | | The implementation of cpu_mmu_index was split between cpu-common.h and cpu-all.h, depending on CONFIG_USER_ONLY. We already have the plumbing common to user and system mode. Using MMU_USER_IDX requires the cpu.h for a specific target, and so is restricted to when we're compiling per-target. Include the new header only where needed.

* tcg: Widen CPUTLBEntry comparators to 64-bitsRichard Henderson2023-06-051-6/+13
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clang's C11 atomic_fetch_*() functions only take a C11 atomic type pointer argument. QEMU uses direct types (int, etc) and this causes a compiler error when a QEMU code calls these functions in a source file that also included <stdatomic.h> via a system header file: $ CC=clang CXX=clang++ ./configure ... && make ../util/async.c:79:17: error: address argument to atomic operation must be a pointer to _Atomic type ('unsigned int *' invalid) Avoid using atomic_*() names in QEMU's atomic.h since that namespace is used by <stdatomic.h>. Prefix QEMU's APIs with 'q' so that atomic.h and <stdatomic.h> can co-exist. I checked /usr/include on my machine and searched GitHub for existing "qatomic_" users but there seem to be none. This patch was generated using: $ git grep -h -o '\<atomic\(64\)\?_[a-z0-9_]\+' include/qemu/atomic.h | \ sort -u >/tmp/changed_identifiers $ for identifier in $(</tmp/changed_identifiers); do sed -i "s%\<$identifier\>%q$identifier%g" \ $(git grep -I -l "\<$identifier\>") done I manually fixed line-wrap issues and misaligned rST tables.

* accel/tcg: Add endian-specific cpu_{ld, st}* operationsRichard Henderson2020-05-111-65/+206
| | | | | | | | | | | | We currently have target-endian versions of these operations, but no easy way to force a specific endianness. This can be helpful if the target has endian-specific operations, or a mode that swaps endianness.
