-Introduction: -------------- -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. -The following heap types are supported by ION driver. -ION_HEAP_TYPE_SYSTEM (0) -ION_HEAP_TYPE_SYSTEM_CONTIG (1) -ION_HEAP_TYPE_CARVEOUT (2) -ION_HEAP_TYPE_CHUNK (3) -ION_HEAP_TYPE_DMA (4) - -By default only the SYSTEM and SYSTEM_CONTIG heaps are supported. -Each heap is associated with the respective heap id. -This utility is designed in the form of client/server program. -The server part (ionapp_export) is the exporter of the buffer. -It is responsible for creating an ION client, allocating the buffer based on -the heap id, writing some data to this buffer and then exporting the FD -(associated with this buffer) to another process using socket IPC. -This FD is called as buffer FD (which is different than the ION client FD). - -The client part (ionapp_import) is the importer of the buffer. -It retrives the FD from the socket data and installs into its address space. -This new FD internally points to the same kernel buffer. -So first it reads the data that is stored in this buffer and prints it. -Then it writes the different size of data (it could be different data) to the -same buffer. -Finally the buffer FD must be closed by both the exporter and importer. -Thus the same kernel buffer is shared among two user space processes using -ION driver and only one time allocation. - -Prerequisite: -------------- -This utility works only if /dev/ion interface is present. -The following configs needs to be enabled in kernel to include ion driver. -CONFIG_ANDROID=y -CONFIG_STAGING=y -CONFIG_ION=y -CONFIG_ION_SYSTEM_HEAP=y - -This utility requires to be run as root user. - - -Compile and test: ------------------ -This utility is made to be run as part of kselftest framework in kernel. -To compile and run using kselftest you can simply do the following from the -kernel top directory. -linux$ make TARGETS=android kselftest -Or you can also use: -linux$ make -C tools/testing/selftests TARGETS=android run_tests -Using the selftest it can directly execute the ion_test.sh script to test the -buffer sharing using ion system heap. -Currently the heap size is hard coded as just 10 bytes inside this script. -You need to be a root user to run under selftest. - -You can also compile and test manually using the following steps: -ion$ make -These will generate 2 executable: ionapp_export, ionapp_import -Now you can run the export and import manually by specifying the heap type -and the heap size. -You can also directly execute the shell script to run the test automatically. -Simply use the following command to run the test. -ion$ sudo ./ion_test.sh - -Test Results: -------------- -The utility is verified on Ubuntu-32 bit system with Linux Kernel 4.14. -Here is the snapshot of the test result using kselftest. - -linux# make TARGETS=android kselftest -heap_type: 0, heap_size: 10 --------------------------------------- -heap type: 0 -
