Subject: [PATCH bpf v9 4/8] selftest/bpf: Enable verifier selftest for powerpc64
Date: Tue, 23 Jun 2026 19:14:07 -0400 [thread overview]
Message-ID: <20260623231411.6216-5-adubey@linux.ibm.com> (raw)
In-Reply-To: <20260623231411.6216-1-adubey@linux.ibm.com>
From: Abhishek Dubey <adubey@linux.ibm.com>
This patch enables arch specifier "__powerpc64" in verifier
selftest for ppc64. Power 32-bit would require separate
handling. Changes tested for 64-bit only.
Signed-off-by: Abhishek Dubey <adubey@linux.ibm.com>
