🌸 qla4xxx_mem_alloc — Kernel API Manual energy ✨

okay so bestie, we're in the qla4xxx_mem_alloc(9) page today — it's a Kernel API Manual situation, very kernel, very driver, and honestly? it's giving "the setup before the main character enters." let's get into it 💅

🎀 NAME

qla4xxx_mem_alloc — it allocates memory for use by adapter. that's the whole vibe. memory goes in, adapter gets to breathe. 💖

✨ SYNOPSIS

int qla4xxx_mem_alloc (struct scsi_qla_host *ha );

that's it. one function, one argument, returns an int. clean. iconic. no notes. 🫶

🦋 ARGUMENTS

  • ha — Pointer to host adapter structure. literally the adapter in question, the one getting all this lovely memory. she's the main character here. 👑

💜 DESCRIPTION

okay so picture this: qla4xxx_mem_alloc allocates DMA memory for the request and response queues. yes, DMA memory, the fancy kind. 🔥

and that's not all — it also allocates memory for srbs. so queues get their DMA memory, srbs get their memory, everyone's fed, everyone's hydrated, slay. 🌈

⭐ SEE ALSO

buckle up bestie, this list is LONG but we're not skipping a single one, because every single cross-reference is a whole person and they all deserve to be named. 👑

Kernel file ./drivers/scsi/qla4xxx/ql4_os.c — she's the home base, the source file, the place where it all lives. 💖

and then the whole friend group, fr fr:

like I said. the whole group chat. go say hi to all of them. 🫶💖

ngl, if you're reading this at 3am in a kernel tree, drink some water and go to bed after. the adapter will still be there. 💀🌸

mwah, that's the page! this little gem lives over in <mint>./drivers/scsi/qla4xxx</mint>, and it's dated October 2026 — so yeah, she's from the future, and she ate. 👑✨🎀
