Hi,
This series carries forward the effort to add Kselftest for PCI Endpoint Subsystem started by Aman Gupta [1] a while ago. I reworked the initial version based on another patch that fixes the return values of IOCTLs in pci_endpoint_test driver and did many cleanups. Since the resulting work modified the initial version substantially, I took over the authorship.
This series also incorporates the review comment by Shuah Khan [2] to move the existing tests from 'tools/pci' to 'tools/testing/kselftest/pci_endpoint' before migrating to Kselftest framework. I made sure that the tests are executable in each commit and updated documentation accordingly.

* Incorporated comments from Niklas * Added a patch to fix the DMA MEMCPY check in pci-epf-test driver * Collected tags * Rebased on top of pci/next 0333f56dbbf7ef6bb46d2906766c3e1b2a04a94d
Changes in v4:
* Dropped the BAR fix patches and submitted them separately: https://lore.kernel.org/linux-pci/20241231130224.38206-1-manivannan.sadhasiv... * Rebased on top of pci/next 9e1b45d7a5bc0ad20f6b5267992da422884b916e
Changes in v3:
* Collected tags. * Added a note about failing testcase 10 and command to skip it in documentation. * Removed Aman Gupta and Padmanabhan Rajanbabu from CC as their addresses are bouncing.
Changes in v2:
* Added a patch that fixes return values of IOCTL in pci_endpoint_test driver * Moved the existing tests to new location before migrating * Added a fix for BARs on Qcom devices * Updated documentation and also added fixture variants for memcpy & DMA modes
