[PATCH v5 4/4] selftests: pci_endpoint: Migrate to Kselftest framework

Manivannan Sadhasivam
2025-01-16T13:51:36Z

Migrate the PCI endpoint test to Kselftest framework. All the tests that
were part of the previous pcitest.sh file were migrated.

Below is the exclusive list of tests:

1. BAR0 Test
2. BAR1 Test
3. BAR2 Test
4. BAR3 Test
5. BAR4 Test
6. BAR5 Test
7. Consecutive BAR Tests
8. Legacy IRQ Tests
9. MSI Interrupt Tests (MSI1 to MSI32)
10. MSI-X Interrupt Tests (MSI-X1 to MSI-X2048)
11. Read Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
12. Write Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
13. Copy Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
14. Read Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
15. Write Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
16. Copy Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)

BAR, DMA and MEMCPY tests are added as fixture variants and can be executed
separately as below:

$ pci_endpoint_test -v BAR0
$ pci_endpoint_test -v dma
$ pci_endpoint_test -v memcpy

+
+Testcase 16 (pci_ep_data_transfer.dma.COPY_TEST) will fail for most of the DMA
+capable endpoint controllers due to the absence of the MEMCPY over DMA. For such
+controllers, it is advisable to skip the forementioned testcase using below
+command::
