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