31  * GFX11 SQ Interrupts
32  *
33  * There are 3 encoding types of interrupts sourced from SQ sent as a 44-bit
34  * packet to the Interrupt Handler:
35  * Auto - Generated by the SQG (various cmd overflows, timestamps etc)
36  * Wave - Generated by S_SENDMSG through a shader program
37  * Error - HW generated errors (Illegal instructions, Memviols, EDC etc)
38  *
39  * The 44-bit packet is mapped as {context_id1[7:0],context_id0[31:0]} plus
40  * 4-bits for VMID (SOC15_VMID_FROM_IH_ENTRY) as such:
41  *
42  * - context_id1[7:6]
43  * Encoding type (0 = Auto, 1 = Wave, 2 = Error)
44  *
45  * - context_id0[26]
46  * PRIV bit indicates that Wave S_SEND or error occurred within trap
47  *
48  * - context_id0[24:0]
49  * 25-bit data with the following layout per encoding type:
50  * Auto - only context_id0[8:0] is used, which reports various interrupts
51  * generated by SQG.  The rest is 0.
52  * Wave - user data sent from m0 via S_SENDMSG (context_id0[23:0])
53  * Error - Error Type (context_id0[24:21]), Error Details (context_id0[20:0])
54  *
55  * The other context_id bits show coordinates (SE/SH/CU/SIMD/WGP) for wave
56  * S_SENDMSG and Errors.  These are 0 for Auto.
