* util/bufferiszero: Add simd acceleration for aarch64Richard Henderson2024-05-031-0/+67
| | | | | | | | | | | | Because non-embedded aarch64 is expected to have AdvSIMD enabled, merely double-check with the compiler flags for __ARM_NEON and don't bother with a runtime check. Otherwise, model the loop after the x86 SSE2 function. Use UMAXV for the vector reduction. This is 3 cycles on cortex-a76 and 2 cycles on neoverse-n1.

* util/bufferiszero: Simplify test_buffer_is_zero_next_accelRichard Henderson2024-05-031-46/+35
| | | | | | | | | | | | Because the three alternatives are monotonic, we don't need to keep a couple of bitmasks, just identify the strongest alternative at startup. Generalize test_buffer_is_zero_next_accel and init_accel by always defining an accel_table array.

| | | | | | | | | Split less-than and greater-than 256 cases. Use unaligned accesses for head and tail. Avoid using out-of-bounds pointers in loop boundary conditions. Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* util/bufferiszero: Optimize SSE2 and AVX2 variantsAlexander Monakov2024-05-031-41/+76
| | | | | | | | | | | | | | | | Increase unroll factor in SIMD loops from 4x to 8x in order to move their bottlenecks from ALU port contention to load issue rate (two loads per cycle on popular x86 implementations). Avoid using out-of-bounds pointers in loop boundary conditions. Follow SSE2 implementation strategy in the AVX2 variant. Avoid use of PTEST, which is not profitable there (like in the removed SSE4 variant).

* util/bufferiszero: Remove useless prefetchesAlexander Monakov2024-05-031-3/+0
| | | | | | | | | | | | | | | | | | Use of prefetching in bufferiszero.c is quite questionable: - prefetches are issued just a few CPU cycles before the corresponding line would be hit by demand loads; - they are done for simple access patterns, i.e. where hardware prefetchers can perform better; - they compete for load ports in loops that should be limited by load port throughput rather than ALU throughput.

* util/bufferiszero: Remove AVX512 variantAlexander Monakov2024-05-031-35/+3
| | | | | | | | | | | | | | | Thanks to early checks in the inline buffer_is_zero wrapper, the SIMD routines are invoked much more rarely in normal use when most buffers are non-zero. This makes use of AVX512 unprofitable, as it incurs extra frequency and voltage transition periods during which the CPU operates at reduced performance, as described in https://travisdowns.github.io/blog/2020/01/17/avxfreq1.html Signed-off-by: Mikhail Romanov <mmromanov@ispras.ru> Signed-off-by: Alexander Monakov <amonakov@ispras.ru> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20240206204809.9859-4-amonakov@ispras.ru> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
* util/bufferiszero: Remove SSE4.1 variantAlexander Monakov2024-05-031-29/+0
| | | | | | | | | | | | | | | | | | | | | | The SSE4.1 variant is virtually identical to the SSE2 variant, except for using 'PTEST+JNZ' in place of 'PCMPEQB+PMOVMSKB+CMP+JNE' for testing if an SSE register is all zeroes. The PTEST instruction decodes to two uops, so it can be handled only by the complex decoder, and since CMP+JNE are macro-fused, both sequences decode to three uops. The uops comprising the PTEST instruction dispatch to p0 and p5 on Intel CPUs, so PCMPEQB+PMOVMSKB is comparatively more flexible from dispatch standpoint. Hence, the use of PTEST brings no benefit from throughput standpoint. Its latency is not important, since it feeds only a conditional jump, which terminates the dependency chain. I never observed PTEST variants to be faster on real hardware.

| * | qga/commands-posix: don't do fork()/exec() when suspending via sysfsAndrey Drobyshev2024-05-011-36/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 246d76eba ("qga: guest_suspend: decoupling pm-utils and sys logic") pm-utils logic is running in a separate child from the sysfs logic. Now when suspending via sysfs we don't really need to do that in a separate process as we only need to perform one write to /sys/power/state. Let's just use g_file_set_contents() to simplify things here. Suggested-by: Daniel P.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When executing guest commands in *nix environment, we repeat the same fork/exec pattern multiple times. Let's just separate it into a single helper which would also be able to feed input data into the launched process' stdin. This way we can avoid code duplication. To keep the history more bisectable, let's replace qmp commands implementations one by one. Also add G_GNUC_UNUSED attribute to the helper and remove it in the next commit.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the commit 25b5ff1a86 ("qga: add mountpoint usage info to GuestFilesystemInfo") we have 2 values reported in guest-get-fsinfo: used = (f_blocks - f_bfree), total = (f_blocks - f_bfree + f_bavail) as returned by statvfs(3). While on Windows guests that's all we can get with GetDiskFreeSpaceExA(), on POSIX guests we might also be interested in total file system size, as it's visible for root user. Let's add an optional field 'total-bytes-privileged' to GuestFilesystemInfo struct, which'd only be reported on POSIX and represent f_blocks value as returned by statvfs(3). While here, also tweak the docs to reflect better where those values come from. Signed-off-by: Andrey Drobyshev <andrey.drobyshev@virtuozzo.com> Reviewed-by: Daniel P.
