It's a completely separate accelerator code, though there's possibility of maybe using it in combined fashion with HIP/ROCm OpenCL (I think there's OpenCL compiler for AIE and AIE-ML, but I'm not sure at how well it works yet)
- sva_ 3y agoAh, I wasn't really aware that there is a separate accelerator in the 7040 series, other than rdna3's wmma.
- p_l 3y agoYeah, it's Xilinx AIE, stuff that was already supported on Linux - but it was differently connected on 7040: the AIE module being connected direct to Infinity Fabric, masquerading as PCIE device, instead of existing PCIE driver which assumed mediation done by on-fpga CPU etc. At least that's how it looked from what I've read in XRT docs so far. This driver both provides necessary interface in place of an ARM core talking direct over AXI buses, and the glue logic to enable use of XRT.
