💅 zynqmp_pm_fpga_load(9) 💅

okay so bestie, welcome to the Kernel API Manual page for zynqmp_pm_fpga_load(9) — the function that does the fpga load. it's giving "bitstream delivery service" and honestly we're obsessed. 🎀

🌸 NAME 🌸

zynqmp_pm_fpga_load — perform the fpga load.

✨ SYNOPSIS ✨

int zynqmp_pm_fpga_load (const u64 address , const u32 size , const u32
       flags );

🎀 ARGUMENTS 🎀

  • address — address to write to. that's the spot, bestie. ✨
  • size — pl bitstream size. yes, the size of the pl bitstream. 💖
  • flags — Bitstream type. here are your options, and yes you need the exact ones:
    • -XILINX_ZYNQMP_PM_FPGA_FULL: FPGA full reconfiguration
    • -XILINX_ZYNQMP_PM_FPGA_PARTIAL: FPGA partial reconfiguration

so the flags argument is literally the bitstream type, and the two names on the menu are -XILINX_ZYNQMP_PM_FPGA_FULL and -XILINX_ZYNQMP_PM_FPGA_PARTIAL. memorize them, they're iconic. 🫶

🦋 DESCRIPTION 🦋

okay so this function provides access to pmufw. the whole point is to transfer the required bitstream into PL. that's the vibe, that's the job. 🌈

💖 RETURN 💖

it returns a status — either success or error+reason. so yeah, success or error+reason, no cap. 😭
