/*
 * GFX9 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_id0[27:26]
 * Encoding type (0 = Auto, 1 = Wave, 2 = Error)
 *
 * - context_id0[13]
 * PRIV bit indicates that Wave S_SEND or error occurred within trap
 *
 * - {context_id1[7:0],context_id0[31:28],context_id0[11:0]}
 * 24-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
 * Error - Error type (context_id1[7:4]), Error Details (rest of bits)
 *
 * The other context_id bits show coordinates (SE/SH/CU/SIMD/WAVE) for wave
 * S_SENDMSG and Errors.  These are 0 for Auto.
