I would drop the link, it does not really add any value. > Signed-off-by: Christian Bruel <[email protected]> > --- > tools/testing/selftests/pci_endpoint/pci_endpoint_test.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/tools/testing/selftests/pci_endpoint/pci_endpoint_test.c > b/tools/testing/selftests/pci_endpoint/pci_endpoint_test.c > index > c417fb3a198b2d92c3060938c23807cc8bea5573..8ea2fda4539d11eb22b22800a7cb8bbaa99c91ba > 100644 > --- a/tools/testing/selftests/pci_endpoint/pci_endpoint_test.c > +++ b/tools/testing/selftests/pci_endpoint/pci_endpoint_test.c > @@ -88,6 +88,8 @@ TEST_F(pci_ep_bar, BAR_SUBRANGE_TEST) > SKIP(return, "Subrange map is not supported"); > if (ret == -ENOBUFS) > SKIP(return, "BAR is reserved"); > + if (ret == -ENOSPC) > + SKIP(return, "Not enough ATU entries to allocate subrange"); ATU is a DWC specific term. I would use "inbound windows" instead. E.g. "Not enough inbound windows to allocate subrange" Considering that the selftests is highest up the stack, I would put this patch as 3/3 and not 1/3.
