Web1.2 Instruction encoding ¶ eBPF has two instruction encodings: the basic instruction encoding, which uses 64 bits to encode an instruction. the wide instruction encoding, which appends a second 64-bit immediate value (imm64) after the basic instruction for a total of 128 bits. The basic instruction encoding looks as follows:
