Address weird state dependency Need to write *something* to VS input registers before writing shader uniforms and code. Otherwise the whole thing will hang when running this first after boot.
This contains various tests for Vivante GPUs based on the Etnaviv DRM driver.
./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.
This package needs libdrm
installed with libdrm_etnaviv
enabled. MESA is not necessary.
This is an extremely basic test that writes “Hello World” to memory from a CL shader.
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:
