Subject: [PATCH v4 3/3] selftests: pci_endpoint: Migrate to Kselftest framework
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. Consecutive BAR Tests
3. Legacy IRQ Tests
4. MSI Interrupt Tests (MSI1 to MSI32)
5. MSI-X Interrupt Tests (MSI-X1 to MSI-X2048)
6. Read Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
7. Write Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
8. Copy Tests - MEMCPY (For 1, 1024, 1025, 1024000, 1024001 Bytes)
9. Read Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
10. Write Tests - DMA (For 1, 1024, 1025, 1024000, 1024001 Bytes)
11. 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)
