If will currently fail because pci-epf-test.c does: if ((reg->flags & FLAG_USE_DMA) && epf_test->dma_private) return -EINVAL; So even if a DMA driver has support for the DMA_MEMCPY cap, if the DMA driver also has the DMA_PRIVATE cap, this test will fail because of the code in pci-epf-test.c. Not sure how to formulate this properly... Perhaps: Testcase 11 (pci_ep_data_transfer.dma.COPY_TEST) will fail for DMA drivers that have the DMA_PRIVATE cap set. For DMA drivers which have the DMA_PRIVATE cap set, it is advisable to skip the forementioned testcase using below command:: > + > + # pci_endpoint_test -f pci_ep_basic -v memcpy -T COPY_TEST -v dma Is this really correct? I would guess that it should be pci_endpoint_test -f pci_ep_data_transfer -v memcpy -T COPY_TEST -v dma (...) > +TEST_F(pci_ep_basic, BAR_TEST) > +{ > + int ret, i; > + > + for (i = 0; i <= 5; i++) { > + pci_ep_ioctl(PCITEST_BAR, i); > + EXPECT_FALSE(ret) TH_LOG("Test failed for BAR%d", i); > + } > +}
