selftests: add headers_install to lib.mk

2018-09-05T14:12:09Z

If the kernel headers aren't installed we can't build all the tests. Add a new make target rule 'khdr' in the file lib.mk to generate the kernel headers and that gets include for every test-dir Makefile that includes lib.mk If the testdir in turn have its own sub-dirs the top_srcdir needs to be set to the linux-rootdir to be able to generate the kernel headers.

selftests/android: initialize heap_type to avoid compiling warning

selftests: android: ion: return Kselftest Skip code for skipped tests

2018-05-30T21:21:52Z

When ion test is skipped because of unmet dependencies and/or unsupported configuration, it returns 0 which is treated as a pass by the Kselftest framework. This leads to false positive result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.

selftests: ion: Add simple test with the vgem driver

2018-03-06T01:56:24Z

Ion is designed to be a framework used by other clients who perform operations on the buffer. Use the DRM vgem client as a simple consumer. In conjunction with the dma-buf sync ioctls, this tests the full attach/map path for the system heap. Signed-off-by: Laura Abbott Reviewed-by: Daniel Vetter Signed-off-by: Shuah Khan

android/ion: userspace test utility for ion buffer sharing

2017-11-15T15:07:53Z

This is a test utility to verify ION buffer sharing in user space between 2 independent processes. It uses unix domain socket (with SCM_RIGHTS) as IPC to transfer an FD to another process to share the same buffer. This utility demonstrates how ION buffer sharing can be implemented between two user space processes, using various heap types. This utility is made to be run as part of kselftest framework in kernel. The utility is verified on Ubuntu-32 bit system with Linux Kernel 4.14, using ION system heap. For more information about the utility please check the README file. Signed-off-by: Pintu Agarwal Signed-off-by: Shuah Khan
