INFRASTRUCTURE CALLS(9)

💅 Infrastructure calls(9) — Kernel API Manual 💅

Okay so bestie, this is the Infrastructure calls(9) page from the Kernel API Manual, and it's giving backstage-access energy. 💖 Here's the whole SDMA infrastructure squad, no cap, nothing skipped. ✨

• sdma_init — used to initialize data structures and CSRs for the desired number of SDMA engines. Setup era, literally. 🛠️
• sdma_start — used to kick the SDMA engines initialized with sdma_init. Interrupts must be enabled at this point since aspects of the state machine are interrupt driven. 🚨
• sdma_engine_error — an entrance for interrupts. 🚪
• sdma_engine_interrupt — also an entrance for interrupts. 🚪✨
• sdma_map_init — for the management of the mapping table when the number of vls is changed. 🗺️
