  30  *
  31  * There are 3 encoding types of interrupts sourced from SQ sent as a 44-bit
  32  * packet to the Interrupt Handler:
  33  * Auto - Generated by the SQG (various cmd overflows, timestamps etc)
  34  * Wave - Generated by S_SENDMSG through a shader program
  35  * Error - HW generated errors (Illegal instructions, Memviols, EDC etc)
  36  *
  37  * The 44-bit packet is mapped as {context_id1[7:0],context_id0[31:0]} plus
  38  * 4-bits for VMID (SOC15_VMID_FROM_IH_ENTRY) as such:
  39  *
  40  * - context_id1[7:6]
  41  * Encoding type (0 = Auto, 1 = Wave, 2 = Error)
  42  *
  43  * - context_id0[24]
  44  * PRIV bit indicates that Wave S_SEND or error occurred within trap
  45  *
  46  * - context_id0[22:0]
  47  * 23-bit data with the following layout per encoding type:
  48  * Auto - only context_id0[8:0] is used, which reports various interrupts
  49  * generated by SQG.  The rest is 0.
  50  * Wave - user data sent from m0 via S_SENDMSG
  51  * Error - Error type (context_id0[22:19]), Error Details (rest of bits)
  52  *
  53  * The other context_id bits show coordinates (SE/SH/CU/SIMD/WGP) for wave
  54  * S_SENDMSG and Errors.  These are 0 for Auto.
