2023-10-03softmmu: Use async_run_on_cpu in tcg_commitRichard Henderson
After system startup, run the update to memory_dispatch and the tlb_flush on the cpu. This eliminates a race, wherein a running cpu sees the memory_dispatch change but has not yet seen the tlb_flush. Since the update now happens on the cpu, we need not use qatomic_rcu_read to protect the read of memory_dispatch.

2023-10-03accel/tcg: mttcg remove false-negative halted assertionNicholas Piggin
mttcg asserts that an execution ending with EXCP_HALTED must have cpu->halted. However between the event or instruction that sets cpu->halted and requests exit and the assertion here, an asynchronous event could clear cpu->halted. This leads to crashes running AIX on ppc/pseries because it uses H_CEDE/H_PROD hcalls, where H_CEDE sets self->halted = 1 and H_PROD sets other cpu->halted = 0 and kicks it. H_PROD could be turned into an interrupt to wake, but several other places in ppc, sparc, and semihosting follow what looks like a similar pattern setting halted = 0 directly. So remove this assertion.

In bef6f008b981, we mechanically invert all callers while changing to false/true return, preserving the incorrectness of the test. Now that the return sense is sane, it's easy to see that if !write, then the page is not modifiable (i.e. most likely read-only, with PROT_NONE handled via SIGSEGV).

2023-07-17accel/tcg: Zero-pad PC in TCG CPU exec trace linesPeter Maydell
In commit f0a08b0913befbd we changed the type of the PC from target_ulong to vaddr. In doing so we inadvertently dropped the zero-padding on the PC in trace lines (the second item inside the [] in these lines). They used to look like this on AArch64, for instance: Trace 0: 0x7f2260000100 [00000000/0000000040000000/00000061/ff200000] and now they look like this: Trace 0: 0x7f4f50000100 [00000000/40000000/00000061/ff200000] and if the PC happens to be somewhere low like 0x5000 then the field is shown as /5000/. This is because TARGET_FMT_lx is a "%08x" or "%016x" specifier, depending on TARGET_LONG_SIZE, whereas VADDR_PRIx is just PRIx64 with no width specifier. Restore the zero-padding by adding an 016 width specifier to this tracing and a couple of others that were similarly recently changed to use VADDR_PRIx without a width specifier. We can't unfortunately restore the "32-bit guests are padded to 8 hex digits and 64-bit guests to 16 hex digits" behaviour so easily.

2023-07-15tcg: Use HAVE_CMPXCHG128 instead of CONFIG_CMPXCHG128Richard Henderson
We adjust CONFIG_ATOMIC128 and CONFIG_CMPXCHG128 with CONFIG_ATOMIC128_OPT in atomic128.h. It is difficult to tell when those changes have been applied with the ifdef we must use with CONFIG_CMPXCHG128. So instead use HAVE_CMPXCHG128, which triggers -Werror-undef when the proper header has not been included. Improves tcg_gen_atomic_cmpxchg_i128 for s390x host, which requires CONFIG_ATOMIC128_OPT. Without this we fall back to EXCP_ATOMIC to single-step 128-bit atomics, which is slow enough to cause some tests to time out.

2023-07-03plugins: force slow path when plugins instrument memory opsAlex Bennée
The lack of SVE memory instrumentation has been an omission in plugin handling since it was introduced. Fortunately we can utilise the probe_* functions to force all all memory access to follow the slow path. We do this by checking the access type and presence of plugin memory callbacks and if set return the TLB_MMIO flag. We have to jump through a few hoops in user mode to re-use the flag but it was the desired effect: ./qemu-system-aarch64 -display none -serial mon:stdio \ -M virt -cpu max -semihosting-config enable=on \ -kernel ./tests/tcg/aarch64-softmmu/memory-sve \ -plugin ./contrib/plugins/libexeclog.so,ifilter=st1w,afilter=0x40001808 -d plugin gives (disas doesn't currently understand st1w): 0, 0x40001808, 0xe54342a0, ".byte 0xa0, 0x42, 0x43, 0xe5", store, 0x40213010, RAM, store, 0x40213014, RAM, store, 0x40213018, RAM And for user-mode: ./qemu-aarch64 \ -plugin contrib/plugins/libexeclog.so,afilter=0x4007c0 \ -d plugin \ ./tests/tcg/aarch64-linux-user/sha512-sve gives: 1..10 ok 1 - do_test(&tests[i]) 0, 0x4007c0, 0xa4004b80, ".byte 0x80, 0x4b, 0x00, 0xa4", load, 0x5500800370, load, 0x5500800371, load, 0x5500800372, load, 0x5500800373, load, 0x5500800374, load, 0x5500800375, load, 0x5500800376, load, 0x5500800377, load, 0x5500800378, load, 0x5500800379, load, 0x550080037a, load, 0x550080037b, load, 0x550080037c, load, 0x550080037d, load, 0x550080037e, load, 0x550080037f, load, 0x5500800380, load, 0x5500800381, load, 0x5500800382, load, 0x5500800383, load, 0x5500800384, load, 0x5500800385, load, 0x5500800386, lo ad, 0x5500800387, load, 0x5500800388, load, 0x5500800389, load, 0x550080038a, load, 0x550080038b, load, 0x550080038c, load, 0x550080038d, load, 0x550080038e, load, 0x550080038f, load, 0x5500800390, load, 0x5500800391, load, 0x5500800392, load, 0x5500800393, load, 0x5500800394, load, 0x5500800395, load, 0x5500800396, load, 0x5500800397, load, 0x5500800398, load, 0x5500800399, load, 0x550080039a, load, 0x550080039b, load, 0x550080039c, load, 0x550080039d, load, 0x550080039e, load, 0x550080039f, load, 0x55008003a0, load, 0x55008003a1, load, 0x55008003a2, load, 0x55008003a3, load, 0x55008003a4, load, 0x55008003a5, load, 0x55008003a6, load, 0x55008003a7, load, 0x55008003a8, load, 0x55008003a9, load, 0x55008003aa, load, 0x55008003ab, load, 0x55008003ac, load, 0x55008003ad, load, 0x55008003ae, load, 0x55008003af (4007c0 is the ld1b in the sha512-sve) Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Cc: Robert Henry <robhenry@microsoft.com> Cc: Aaron Lindsay <aaron@os.amperecomputing.com> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20230630180423.558337-20-alex.bennee@linaro.org>
