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