Faithful Phoronix readers should recall POCL as the Portable Computing Language project working to provide an open-source OpenCL implementation that can be run on CPUs and other targets. One of the initiatives being worked on more recently by POCL developers is an HSA driver.

The Portable Computing Language project has been working on a POCL HSA driver for supporting the Heterogeneous System Architecture and so far this code is supporting AMD Kaveri APUs. Last month POCL developers posted a progress report on their HSA driver. I hadn't seen the report mentioned anywhere else and only stumbled across it this weekend when having some GPGPU benchmarking fun.

The POCL HSA driver report can be found via their documentation. As of the middle of May, the HSA support included global/local/private memory, barriers, most of the OpenCL 1.2 kernel built-ins, OpenCL 2.0 Shared Virtual Machine, and OpenCL 2.0 Atomics. But notable items missing include GPU device support aside from AMD Kaveri APUs, support for 32-bit HSA devices, image support, and various built-ins that are still missing. There also isn't yet a proper printf() function wired in.

Those curious about this POCL HSA work can visit the POCL.org documentation.
