We don't use piglet on android. Piglet does not know about adb. Piglet expects to be running on the system under test not on a separate host.
The main aim of this is because on android we are not testing a driver which is drm-nightly. The kernel / display driver used on android will not have all the features that are in the latest linux kernel. We keep hitting problems where new subtests get added to IGT to test features that are not yet in the android kernel. We run and report tests at a binary level as that is what the project managers expect. We wish to be able to run the latest versions of IGT to pick up bug fixes and useful test changes, but want a way of being able to exclude subtests that are not currently appropriate on android without having to exclude complete test binaries. The specific subtests which need to be excluded will differ depending on the HW (CHV vs BXT for example) and specific driver version in the build under test so we need a simple mechanism to specify the subtests to run or exclude (depending on which is more appropriate) for each test.
