2023-08-31target/arm: Support more GM blocksizesRichard Henderson
Support all of the easy GM block sizes. Use direct memory operations, since the pointers are aligned. While BS=2 (16 bytes, 1 tag) is a legal setting, that requires an atomic store of one nibble. This is not difficult, but there is also no point in supporting it until required. Note that cortex-a710 sets GM blocksize to match its cacheline size of 64 bytes. I expect many implementations will also match the cacheline, which makes 16 bytes very unlikely.

2023-07-31target/arm/tcg: Don't build AArch64 decodetree files for qemu-system-armPeter Maydell
Currently we list all the Arm decodetree files together and add them unconditionally to arm_ss. This means we build them for both qemu-system-aarch64 and qemu-system-arm. However, some of them are AArch64-specific, so there is no need to build them for qemu-system-arm. (Meson is smart enough to notice that the generated .c.inc file is not used by any objects that go into qemu-system-arm, so we only unnecessarily run decodetree, not anything more heavyweight like a recompile or relink, but it's still unnecessary work.)

2023-07-31target/arm: Avoid writing to constant TCGv in trans_CSEL()Peter Maydell
In commit 0b188ea05acb5 we changed the implementation of trans_CSEL() to use tcg_constant_i32(). However, this change was incorrect, because the implementation of the function sets up the TCGv_i32 rn and rm to be either zero or else a TCG temp created in load_reg(), and these TCG temps are then in both cases written to by the emitted TCG ops. The result is that we hit a TCG assertion: qemu-system-arm: ../../tcg/tcg.c:4455: tcg_reg_alloc_mov: Assertion `!temp_readonly(ots)' failed. (or on a non-debug build, just produce a garbage result) Adjust the code so that rn and rm are always writeable temporaries whether the instruction is using the special case "0" or a normal register as input.

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>

2023-06-20meson: Replace softmmu_ss -> system_ssPhilippe Mathieu-Daudé
We use the user_ss[] array to hold the user emulation sources, and the softmmu_ss[] array to hold the system emulation ones. Hold the latter in the 'system_ss[]' array for parity with user emulation. Mechanical change doing: $ sed -i -e s/softmmu_ss/system_ss/g $(git grep -l softmmu_ss) Signed-off-by: Philippe Mathieu-Daudé <philmd@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20230613133347.82210-10-philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
