💅 flush_dcache_range_chunked(9) 💅

okay so bestie, this page comes from the Kernel API Manual, and it's giving “clean up the data cache, but make it chunked” energy. Let’s get into it 💖

✨ NAME ✨

flush_dcache_range_chunked — write any modified data cache blocks out to memory and invalidate them, in chunks of up to FLUSH_CHUNK_SIZE. Does not invalidate the corresponding instruction cache blocks. periodt.

🦋 SYNOPSIS 🦋

void flush_dcache_range_chunked (unsigned long start , unsigned long stop , unsigned long chunk );

🎀 ARGUMENTS 🎀

• start — the start address. literally where the cache-flushing moment begins ✨
• stop — the stop address (exclusive). so it stops before this one, no sneaky inclusive behavior 💅
• chunk — the max size of the chunks. keeps the whole thing from being one giant main-character flush 🫶
