 		Detect x2APIC and AVX512 for AMD CPUs and update tests 
AVX512 is supported since Zen 4, meaning all Zen 4 CPUs are x86-64-v4.
x2APIC and AVX512 are present in 'Processor Programming Reference (PPR) for AMD Family 19h Model 11h, Revision B1'.

6c87edab5a Remove CPU_ prefix from x86 cpu_feature_level_t enum options 
This makes the option names of cpu_feature_level_t consistent
and it also makes it easier to list options of the cpu_feature_t
enum just by their prefix (because it now doesn't collide with
the prefix of cpu_feature_level_t options).

/home/runner/work/libcpuid/libcpuid/libcpuid/cpuid_main.c:450:44: warning: unused parameter 'logical_cpu' [-Wunused-parameter]

 		Fix scanf() format for 'logical_cpu' in cpuid_deserialize_raw_data_internal() 
logical_cpu is an uint16_t, so SCNu16 is the correct format. It was providing strange values with SCNi16, like with the Intel® Xeon® Platinum 8280 dump.

 		Provide raw for logical CPU 0 in cpuid_get_raw_data_core() even if set_cpu_affinity() is not supported 
On OpenBSD, set_cpu_affinity() is not supported, so cpuid_get_raw_data_core() always returns ERR_INVCNB.
This commit allows to provide raw data for at least one CPU core.

 		Do not set 'with_affinity' in cpu_raw_data_array_t_constructor() when set_cpu_affinity() is not supported 2024-07-27 17:41:58 +02:00

 		Improve set_cpu_affinity() on NetBSD 
By default, running libcpuid as regular user on NetBSD shows nothing: set_cpu_affinity() fails quietly so cpu_identify_all() is not able to get raw data.
This commit display a warning when an unallowed user try to set CPU affinity.

 		Print a warning for unsupported CPU architectures

 		Fix warnings about sscanf() and printf() formats 
I do not have them on GCC (Linux x86_64), but it complains on macOS and Windows according to CI: https://github.com/anrieff/libcpuid/actions/runs/9731746775/job/26856558997
inttypes seems to be a better portable way to handle type like uint64_t.

0b47460256 Rewrite cpu_identify_all() function to support heterogeneous RAW dumps 
For Meteor Lake CPUs, performance and efficiency cores are mixed (unlike previous CPU generations), so the approach needs to be revisited.
