/* 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.
