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

2018-05-30T21:21:52+00:00

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/android/ion: Makefile: fix build error

2018-03-21T16:40:04+00:00

Fails to build iomap_test.c due to missing include

gcc  -I. -I../../../../../drivers/staging/android/uapi/ -Wall -O2 -g
ionmap_test.c ipcsocket.c ionutils.c   -o ionmap_test
ionmap_test.c:12:27: fatal error: linux/dma-buf.h: No such file or
directory
 #include 
                           ^
compilation terminated.
: recipe for target 'ionmap_test' failed
make[2]: *** [ionmap_test] Error 1

In the current code, we add a new -I ../../../../../usr/include/ to the
INCLUDEDIR variable. Also add ionmap_test to the .gitignore file.

selftests: ion: Add simple test with the vgem driver

2018-03-06T01:56:24+00:00

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.

android/ion: userspace test utility for ion buffer sharing

2017-11-15T15:07:53+00:00

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.
