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. BAR Tests (BAR0 to BAR5) 2. Legacy IRQ Tests 3. MSI Interrupt Tests (MSI1 to MSI32) 4. MSI-X Interrupt Tests (MSI-X1 to MSI-X2048) 5. Read Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes) 6. Write Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes) 7. Copy Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes) 8. Read Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes) 9. Write Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes) 10. Copy Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
DMA and MEMCPY tests are added as fixture variants and can be executed separately as below:
$ pci_endpoint_test -V dma (excluding DMA tests) $ pci_endpoint_test -V memcpy (excluding MEMCPY tests)
