XSDFEC_ADD_LDPC_CODE_PARAMS(9)

💅 XSDFEC_ADD_LDPC_CODE_PARAMS(9) 💅

okay bestie, welcome to the Kernel API Manual entry for XSDFEC_ADD_LDPC_CODE_PARAMS — yes that's a whole mouthful, no we're not changing it, it's iconic as is ✨

🎀 Parameters 🎀

• struct xsdfec_ldpc_params * — a pointer to the struct xsdfec_ldpc_params that's carrying all the LDPC code parameters you wanna add to the SD-FEC Block 💖 like it's literally the little suitcase of settings, and the kernel is gonna unpack it for you.

🌸 Description 🌸

so this one is an ioctl that adds an LDPC code to the SD-FEC LDPC codes. that's the whole vibe. the way it just… adds the code 🦋

but ngl, it's picky — it does not work unless all of these are true:

• the Driver is in the XSDFEC_STOPPED state 💀 (yeah, stopped, not running, it's giving "closed for business")
• the SD-FEC core is configured as LPDC 👑
• the SD-FEC Code Write Protection is disabled 🔓

lowkey respect the boundaries fr fr, it's just protecting its peace 🫶
