HI all,
I would appreciate your feedback on the following issue I am having.
I have an OpenCL platform that is composed of a microblaze processor as the
host, and device(s) that are connected to the microblaze processor. The
platform is an embedded system (all these elements are on a single die).
The host runs linux, and has a toolchain built for it
(microblazeel-xilinx-linux-gnu-).
The microblaze (host) is connected to the device using a special peripheral
that requires the use of a special instruction (processor instruction). As
a result, I would need to modify the OpenCL library source to use this
special instruction. So, my first question is: where can I download the
OpenCL library source? Is it incorporated into pocl? If so, where?
Once I have modified the OpenCL library source to use the special
instruction and conform to my platform specifications, I would need to
compile this library using the toolchain (microblazeel-xilinx-linux-gnu-).
When the OpenCL library is complete, I would need to build the OpenCL
framework, so I can execute kernels on the device(s), which I assume that
is the main contribution of pocl. When I attempt to build pocl using the
following command: "./configure --host=microblazeel-xilinx-linux-gnu-", I
get the following error:
"checking host system type... Invalid configuration
`microblazeel-xilinx-linux-gnu-': machine `microblazeel-xilinx-linux-gnu'
not recognized
configure: error: /bin/sh config/config.sub microblazeel-xilinx-linux-gnu-
failed"
Effectively, I am cross-compiling pocl with the build machine as my
workstation, and the target machine as the opencl platform I previously
described. What am I doing wrong when building pocl? Another question that
I have is: are my steps correct? Is my logic for solving the issue correct?
My final question is: does the above reasoning/explanation make any sense?
Thank you in advance,

Vince
