| |
This patchset introduces a testing framework for Hyper-V drivers. This framework allows us to introduce delays in the packet receive path on a per-device basis. While the current code only supports introducing arbitrary delays in the host/guest communication path, we intend to expand this to support error injection in the future.
changes in v3: patch 2: change call to IS_ERR_OR_NULL, to IS_ERR.
patch 3: Align python tool to match Linux coding style.
Changes in v2: Patch 1: As per Vitaly's suggestion, wrapped the test code under an #ifdef and updated the Kconfig file, so that the test code will only be used when the config option is set to true. (default is false).
Updated hyperv_vmbus header to contain new #ifdef with new new functions for the test code.
Patch 2: Moved code from under sysfs to debugfs and wrapped it under the new ifdef.
Updated MAINTAINERS file with new debugfs-hyperv file under the section for hyperv.
Patch 3: Updated testing tool with new debugfs location.
Branden Bonaby (3): drivers: hv: vmbus: Introduce latency testing drivers: hv: vmbus: add fuzz test attributes to debugfs tools: hv: add vmbus testing tool
