Manivannan, the patch link you have provided cannot be directly applies on the latest kernel and hence it requires some re work .I can rework these patches along with the kselftest patch if not please allow me to go ahead and post the kselftest patch till then. > > > > Looks like we might end up removing the tests under tools/pci and just use > this one. I will CC you on the v3 of PCI test cleanup series. Please rebase this > patch on top of that and post after incorporating the review comments. Okay, I will rebase the patches after v3 clean up gets posted. > > Thanks, > Mani > > > Thanks, > > Mani > > > > > + TH_LOG("TEST FAILED FOR BAR %d\n", i); > > > + final++; > > > + } > > > + } > > > + > > > + ASSERT_EQ(0, final); > > > +} > > > + > > > +TEST_F(device, MSI_TEST) > > > +{ > > > + int ret = -EINVAL; > > > + int final = 0; > > > + > > > + ret = ioctl(self->fd, PCITEST_SET_IRQTYPE, 1); > > > + ASSERT_EQ(1, ret); > > > + > > > + for (int i = 1; i <= 32; i++) { > > > + ret = ioctl(self->fd, PCITEST_MSI, i); > > > + EXPECT_EQ(1, ret) { > > > + TH_LOG("TEST FAILED FOR MSI%d\n", i); > > > + final++; > > > + } > > > + } > > > + > > > + ASSERT_EQ(0, final); > > > +} > > > + > > > +TEST_F(device, READ_TEST) > > > +{ > > > + int final = 0; > > > + int ret = -EINVAL; > > > + unsigned long SIZE[5] = {1, 1024, 1025, 1024000, 1024001}; > > > + > > > + ret = ioctl(self->fd, PCITEST_SET_IRQTYPE, 1); > > > + ASSERT_EQ(1, ret); > > > + > > > + struct xfer_param param; > > > + > > > + param.flag = 0; > > > + for (int i = 0; i < 5; i++) { > > > + param.size = SIZE[i]; > > > + ret = ioctl(self->fd, PCITEST_READ, ¶m); > > > + EXPECT_EQ(1, ret) { > > > + TH_LOG("TEST FAILED FOR size =%ld.\n", SIZE[i]); > > > + final++; > > > + } > > > + } > > > + > > > + ASSERT_EQ(0, final); > > > +} > > > + > > > +TEST_F(device, WRITE_TEST) > > > +{ > > > + int final = 0; > > > + int ret = -EINVAL; > > > + unsigned long SIZE[5] = {1, 1024, 1025, 1024000, 1024001}; > > > + > > > + ret = ioctl(self->fd, PCITEST_SET_IRQTYPE, 1); > > > + ASSERT_EQ(1, ret); > > > + > > > + struct xfer_param param; > > > + > > > + param.flag = 0; > > > + > > > + for (int i = 0; i < 5; i++) { > > > + param.size = SIZE[i]; > > > + ret = ioctl(self->fd, PCITEST_WRITE, ¶m); > > > + EXPECT_EQ(1, ret) { > > > + TH_LOG("TEST FAILED FOR size =%ld.\n", SIZE[i]); > > > + final++; > > > + } > > > + } > > > + > > > + ASSERT_EQ(0, final); > > > +} > > > + > > > +TEST_F(device, COPY_TEST) > > > +{ > > > + int final = 0; > > > + int ret = -EINVAL; > > > + unsigned long SIZE[5] = {1, 1024, 1025, 1024000, 1024001}; > > > + > > > + ret = ioctl(self->fd, PCITEST_SET_IRQTYPE, 1); > > > + ASSERT_EQ(1, ret); > > > + > > > + struct xfer_param param; > > > + > > > + param.flag = 0; > > > + > > > + for (int i = 0; i < 5; i++) { > > > + param.size = SIZE[i]; > > > + ret = ioctl(self->fd, PCITEST_COPY, ¶m); > > > + EXPECT_EQ(1, ret) { > > > + TH_LOG("TEST FAILED FOR size =%ld.\n", SIZE[i]); > > > + final++; > > > + } > > > + } > > > + > > > + ASSERT_EQ(0, final); > > > +} > > > +TEST_HARNESS_MAIN > > > -- > > > 2.17.1 > > > > > > > -- > > மணிவண்ணன் சதாசிவம் > > -- > மணிவண்ணன் சதாசிவம் Thank you for reviewing the patch.
