[PATCH v2 0/4] Migrate PCI Endpoint Subsystem tests to Kselftest
From: Manivannan Sadhasivam
Date: Fri Nov 29 2024 - 04:25:12 EST
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.
NOTE: Patch 1 is strictly not related to this series, but necessary to execute
Kselftests with Qualcomm Endpoint devices. So this can be merged separately.
