uds_prefetch_address(9)

✨ uds_prefetch_address(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is a little function with big main-character energy 🎀

💖 NAME 💖

uds_prefetch_address — the way that this literally minimizes cache-miss latency by attempting to move data into a CPU cache before it gets accessed. it's giving "manifesting your data into the right place ahead of time" 🦋

🌸 SYNOPSIS 🌸

void uds_prefetch_address (const void *address , bool for_write );

🫶 ARGUMENTS 🫶

• address — the address to fetch. and no, bestie, it does not have to be valid — it may be invalid, so like… be aware of that 😭
• for_write — this one has to be constant at compile time, no cap. pass false if you're reading, true if you're writing 💅

🌈 SEE ALSO 🌈

• the Kernel file ./drivers/md/dm-vdo/cpu.h
• uds_prefetch_range(9)

and that's the whole page, periodt 💜 go forth and prefetch responsibly, and remember: compile-time constant means compile-time constant 🙈
