[PATCH v1 0/2] selftests/x86: Skip int80 if not supported

From: Slawomir Rosek
Date: Wed Dec 17 2025 - 09:07:09 EST


The IA32 Emulation support can be either removed from the kernel,
disabled by default or disabled at runtime. Some of x86 selftests
are crashing for all of above thus is_32bit_syscall_supported()
helper is added to skip int80 syscalls if they are not supported.

Slawomir Rosek (2):
selftests/x86/ldt_gdt: Skip int80 if not supported
selftests/x86/ptrace_syscall: Skip int80 if not supported
