| Etnaviv GPU tests |
| =================== |
| |
| This contains various tests for Vivante GPUs based on the Etnaviv DRM driver. |
| |
| Building |
| ----------- |
| |
| ./autogen.sh |
| ./configure |
| make |
| |
| For cross-builds simply pass `--host=<toolchain-tuple>` to `configure`. You may |
| have to override `PKG_CONFIG_PATH` `PKG_CONFIG_SYSROOT_DIR` `PKG_CONFIG_LIBDIR` |
| as well to make it able to find the DRM libraries. |
| |
| Dependencies |
| ------------- |
| |
| This package needs `libdrm` installed with `libdrm_etnaviv` enabled. MESA is |
| not necessary. |
| |
| Tests |
| ------ |
| |
| ### etnaviv_cl_test |
| |
| This is an extremely basic test that writes "Hello World" to memory |
| from a CL shader. |
| |
| ### etnaviv_verifyops |
| |
| The intent of this test is to test the output of various opcodes against |
| putative CPU implementation of the same operation, and thus figure out exactly |
| what the GPU instructions do. |
| |
| This is achieved by using the `CL` (OpenCL) functionality of GC2000 and higher. |
| |
| Example output: |
| |
| $ etnaviv_verifyops /dev/dri/renderD128 |
