dfl_fpga_enum_info_add_dfl(9)

hiii bestie!! welcome to dfl_fpga_enum_info_add_dfl(9), straight outta the Kernel API Manual 💅✨

🏷️ NAME

dfl_fpga_enum_info_add_dfl — add info of a device feature list to enum info 🎀

✨ SYNOPSIS

int dfl_fpga_enum_info_add_dfl (struct dfl_fpga_enum_info *info ,
       resource_size_t start , resource_size_t len );

🫶 ARGUMENTS

• info — ptr to dfl_fpga_enum_info 💖
• start — mmio resource address of the device feature list.
• len — mmio resource length of the device feature list.

🌸 DESCRIPTION

okay so bestie, one FPGA device may have one or more Device Feature Lists (DFLs) 👑 use this function to add information of each DFL to the common data structure for the next step enumeration. it's giving "organize the info so enumeration can slay later" ✨

🔥 RETURN

0 on success, negative error code otherwise. periodt 💀
