plpks_get_ma...geobjectsize(9)

okay so bestie, welcome to the plpks_get_ma...geobjectsize(9) page from the Kernel API Manual ✨ this one is all about the maximum object size for newer PLPKS config structures, and it’s lowkey iconic 💅

💖 NAME 💖

plpks_get_maxlargeobjectsize — get the maximum object size supported for PLPKS config structure version >= 3 🎀

✨ SYNOPSIS ✨

u32 plpks_get_maxlargeobjectsize (void );

🎀 ARGUMENTS 🎀

• void — no arguments, literally none, bestie 🫶

🦋 DESCRIPTION 🦋

okay so here’s the lore: successful execution of the H_PKS_GET_CONFIG HCALL during initialization reads the maximum object size into the local static maxlargeobjectsize variable for PLPKS config structure version >= 3 🌸

this was introduced starting with PLPKS config structure version 3 to allow for objects of size >= 64K 🔥 so yeah, bigger objects got the green light, no cap 🫶

🔥 RETURN 🔥

• if PLPKS config structure version >= 3, then the new maximum object size is returned ✨
• if not, it’s 0 😌
