+// Navi3 : Clear SGPRs, VGPRs and LDS
+// Launch 32 waves per CU (16 per SIMD) as a workgroup (threadgroup) to fill every wave slot
+// Waves are "wave32" and have 64 VGPRs each, which uses all 1024 VGPRs per SIMD
+// Waves are launched in "CU" mode, and the workgroup shares 64KB of LDS (half of the WGP's LDS)
+// It takes 2 workgroups to use all of LDS: one on each CU of the WGP
+// Each wave clears SGPRs 0 - 107
+// Each wave clears VGPRs 0 - 63
+// The first wave of the workgroup clears its 64KB of LDS
+// The shader starts with "S_BARRIER" to ensure SPI has launched all waves of the workgroup
+// before any wave in the workgroup could end. Without this, it is possible not all SGPRs get cleared.
