Linux support #10
Description
Hi @jpsdr,
thank you for your good work. I'm wondering, if there are any plans on porting NNEDI3 to AVS+ & Linux. I got it compiling with cmake/make for some parts, but got:
nnedi3/PlanarFrame.cpp: In function ‘int CPUCheckForExtensions()’:
nnedi3/PlanarFrame.cpp:57:3: error: ‘__cpuid’ was not declared in this scope
57 | __cpuid(cpuinfo, 1);
| ^~~~~~~
nnedi3/PlanarFrame.cpp:87:42: error: ‘_XCR_XFEATURE_ENABLED_MASK’ was not declared in this scope
87 | unsigned long long xgetbv0 = _xgetbv(_XCR_XFEATURE_ENABLED_MASK);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
nnedi3/PlanarFrame.cpp:87:34: error: ‘_xgetbv’ was not declared in this scope; did you mean ‘xgetbv0’?
87 | unsigned long long xgetbv0 = _xgetbv(_XCR_XFEATURE_ENABLED_MASK);
| ^~~~~~~
| xgetbv0
After adding #include <x86gprintrin.h> to PlanarFrame.cpp I was left with:
nnedi3/PlanarFrame.cpp: In function ‘int CPUCheckForExtensions()’:
nnedi3/PlanarFrame.cpp:57:3: error: ‘__cpuid’ was not declared in this scope
57 | __cpuid(cpuinfo, 1);
| ^~~~~~~
nnedi3/PlanarFrame.cpp:87:42: error: ‘_XCR_XFEATURE_ENABLED_MASK’ was not declared in this scope
87 | unsigned long long xgetbv0 = _xgetbv(_XCR_XFEATURE_ENABLED_MASK);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
Now finally with
#ifdef __linux__
#include <x86gprintrin.h>
#define _aligned_malloc(size, alignment) aligned_alloc(alignment, size)
#define _aligned_free(ptr) free(ptr)
#define _XCR_XFEATURE_ENABLED_MASK 0
#define __cpuid(out, infoType)\
asm("cpuid": "=a" (out[0]), "=b" (out[1]), "=c" (out[2]), "=d" (out[3]): "a" (infoType));
#endif
I'm "only" left with:
