Subject: [PATCH 9/9] selftests: pci_endpoint: Skip reserved BARs
Date: Tue, 17 Feb 2026 22:27:15 +0100 [thread overview]
Message-ID: <20260217212707.2450423-20-cassel@kernel.org> (raw)
In-Reply-To: <20260217212707.2450423-11-cassel@kernel.org>
Running a test against a reserved BAR will result in the pci-epf-test
driver returning -ENOBUFS.
Make sure that the pci_endpoint_test selftest will return skip instead of
failure or success for reserved BARs.
