asd_init_ctxmem(9)

💅 asd_init_ctxmem(9) 💅

okay so bestie, this page is straight out of the Kernel API Manual, and it’s literally about asd_init_ctxmem(9). No cap, it’s giving “context memory setup” energy. Let’s get into it 🫶

💖 NAME 💖

asd_init_ctxmem — initialize context memory. That’s the whole vibe: it sets up context memory, periodt.

🌸 SYNOPSIS 🌸

int asd_init_ctxmem (struct asd_ha_struct *asd_ha );

🎀 ARGUMENTS 🎀

• asd_ha — pointer to host adapter structure. Iconic pointer behavior, honestly.

🦋 DESCRIPTION 🦋

So this function sets the maximum number of SCBs and DDBs that can be used by the sequencer. Normally? That’s 512 and 128 respectively — that’s the normal setup, bestie, write it down. ✨

If support for more SCBs or more DDBs is required, then CMDCTXBASE, DEVCTXBASE and CTXDOMAIN are initialized here to extend context memory to point to host memory. The way that works is it allows unlimited support for SCBs and DDBs — only limited by host memory. Like, host memory is the limit here, not the SCB/DDB count. 💅
