14 The old format had two registers A and X, and a hidden frame pointer. The
15 new layout extends this to be 10 internal registers and a read-only frame
50 ABI, thus, there won't be able to use a direct eBPF register to HW register
75 a return value of the function. Since R6 - R9 are callee saved, their state
81 u64 f2(u64 a) { return f3(a + 1, a); }
82 u64 f3(u64 a, u64 b) { return a - b; }
202 program will terminate quickly and will only call a fixed number of kernel
207 its content is defined by a specific use case. For seccomp register R1 points
208 to seccomp_data, for converted BPF filters R1 points to a skb.
218 eBPF is a general purpose RISC instruction set. Not every register and
225 eBPF can be used as a generic assembler for last step performance
233 Just like the original BPF, eBPF runs within a controlled environment,
336 Classic BPF wastes the whole BPF_RET class to represent a single ``ret``
340 value into register R0 before doing a BPF_EXIT. Class 6 in eBPF is used as
