[PATCH v2 4/4] selftests: pci_endpoint: Migrate to Kselftest framework

Manivannan Sadhasivam
2024-11-29T09:27:23Z

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)
