@bdyb I'm not the maintainer anymore, and the upstream actually supports kernel 7.2 already, you can flag this package out-of-date to notify @zen to update this package.

@detian zenergy does not report total socket power (at least on zen3 CPUs).

It would be better to patch the source to make it build for 7.2 For example something like this

prepare() {
    sed -e "s/@CFLGS@//" \
        -e "s/@VERSION@/$pkgver/" \
        -i "$srcdir/$_pkgname/dkms.conf"

    # Patch cpuid_ecx for Kernel 7.2 compatibility
    python3 -c "
path = '$srcdir/$_pkgname/zenpower.c'
with open(path, 'r') as f:
    content = f.read()

target = 'data->nodes_per_cpu = 1 + ((cpuid_ecx(0x8000001E) >> 8) & 0b111);'
replacement = '''unsigned int eax, ebx, ecx, edx;
\t\tasm volatile(\"cpuid\" : \"=a\" (eax), \"=b\" (ebx), \"=c\" (ecx), \"=d\" (edx) : \"0\" (0x8000001E));
\t\tdata->nodes_per_cpu = 1 + ((ecx >> 8) & 0b111);'''

if target in content:
    content = content.replace(target, replacement)
    with open(path, 'w') as f:
        f.write(content)
"
} 

I recommend using zenergy + k10temp as the replacement for zenpower.

@dreieck OK Updated!

Ahoj,

please add
sed -i "s/-Wimplicit-fallthrough=3/-Wimplicit-fallthrough/" "$srcdir/$_pkgname/Makefile"
to prepare(), otherwise build fails for clang compiled kernels with

error: unknown warning option '-Wimplicit-fallthrough=3'; did you mean '-Wimplicit-fallthrough'? [-Werror,-Wunknown-warning-option]

Regards!

Thank you, everything works.

@jongeduard Updated.
