💅 asd_init_scbs(9) 💅

okay bestie, this page is from the Kernel API Manual — and it's all about manually allocating the first SCB. it's giving "setup era, but make it cute." 🫶

✨ NAME ✨

asd_init_scbs — manually allocate the first SCB.

🎀 SYNOPSIS 🎀

int asd_init_scbs (struct asd_ha_struct *asd_ha );

💖 ARGUMENTS 💖

• asd_ha — pointer to host adapter structure.

🌸 DESCRIPTION 🌸

okay so this one allocates the very first SCB — the one that would be sent to the sequencer for execution. its bus address is written to CSEQ_Q_NEW_POINTER, mode page 2, mode 8. ✨

and here's the why, bestie: the bus address of the next scb to be DMA-ed to the host adapter is read from the last SCB DMA-ed to the host adapter. so we have to always stay one step ahead of the sequencer and keep one SCB already allocated. literally cannot be caught lacking. 💅
