| /* Read the payload of an Intel PT packet. |
| * |
| * Reads the payload of the packet starting at @pos into @packet. |
| * |
| * For pt_pkt_read_psb(), the @packet parameter is omitted; the function |
| * validates that the payload matches the expected PSB pattern. |
| * |
| * Decoding an unknown packet uses @config's decode callback. If the callback |
| * is NULL, pt_pkt_read_unknown() returns -pte_bad_opc. |
| * |
| * Beware that the packet opcode is not checked. The caller is responsible |
| * for checking the opcode and calling the correct packet read function. |
| * |
| * Returns the packet size on success, a negative error code otherwise. |
| * Returns -pte_bad_packet if the packet payload is corrupt. |
| * Returns -pte_eos if the packet does not fit into the trace buffer. |
| * Returns -pte_internal if @packet, @pos, or @config is NULL. |
