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>

2024-01-25linux-gen: time: improve TSC frequency measurementJanne Peltonen
Speed up TSC frequency measurement and thus ODP startup by reducing the measurement duration. Make the result more accurate despite the decreased duration by using a busyloop instead of nanosleep and by taking the median of several measurements. Using a busyloop instead of nanosleep also fixes the measurement in (old) systems that have constant but not invariant TSC which may stop or change frequency in C-states.

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).

2016-03-31linux-generic: sysinfo: handle missing @ sign in CPU modelJuha-Matti Tilli
Previously, the sysinfo cpuinfo parser assumed that every CPU model has an @ sign, after which comes the maximum CPU frequency. However, many environments such as virtualized KVM environments have CPU models not having @ sign such as "Intel Xeon E312xx (Sandy Bridge)". The result of the missing @ sign was that the ODP program crashed. The fix is to not assume the @ sign is always there. This may leave cpu_hz_max uninitialized, but then again this is already what is done if the string after @ does not conform to the pattern.
