2024-04-16linux-gen: hash: use unaligned types in _odp_hash_crc32c()Jere Leppänen
Since the data is not necessarily aligned, use unaligned types to read it, in order to avoid undefined behavior. Fixes GCC undefined sanitizer errors: hash_crc32.h:35:24: runtime error: load of misaligned address 0x0000005e12d4 for type 'const uint64_t', which requires 8 byte alignment hash_crc32.h:40:14: runtime error: load of misaligned address 0x0000005ff879 for type 'const uint32_t', which requires 4 byte alignment hash_crc32.h:51:47: runtime error: load of misaligned address 0x0000005e67af for type 'const uint16_t', which requires 2 byte alignment Signed-off-by: Jere Leppänen <jere.leppanen@nokia.com> Reviewed-by: Janne Peltonen <janne.peltonen@nokia.com>
2024-03-18linux-gen: update copyright formatMatias Elo
Update all implementation files to use the new shorter copyright format: /* SPDX-License-Identifier: BSD-3-Clause * Copyright (c) <YEAR> <COPYRIGHT HOLDER> */ Inherited DPDK copyright messages have also been updated to utilize SPDX format and now list the original source files.

2023-07-12linux-gen: sync: implement new memory barriersPetri Savolainen
Implement the new load and store synchronization barriers with x86 and aarch64 instructions. The default implementation falls back to the strongest GCC built-in (__sync_synchronize()), which would be the strong enough on x86 (mfence), but too weak on aarch64 (dmb).

2023-06-21linux-gen: time: refactor implementationMatias Elo
Refactor time codebase to enable more optimized architecture specific implementations. After this commit x86 and aarch64 architectures are assumed to always have support for HW time. The fallback to POSIX time functions has been removed from these architectures for improved performance.

2021-09-30linux-gen: cpu: refactor inlining codeMatias Elo
Refactor CPU ABI and implementation files to follow common project inlining style. odp_cpu_pause() function is now defined only once per architecture. After this clean-up it's simpler for an implementation to add inlined versions of CPU module functions.

2018-05-28linux-gen: cpu: inline cpu cycle functions on x86Petri Savolainen
Moved cpu cycle and pause functions into arch/x86/odp_arch_cpu_inlines.h. Uncommented pause function in spec file and removed it from ABI file. It's safer for ABI compat mode to not have code included into ABI spec files. Other architectures use the default odp_arch_cpu_inlines.h, which does not change the current implementation.
