drm_clflush_pages(9)

✨ NAME ✨

okay bestie, meet drm_clflush_pages(9) — it’s the Kernel API Manual page that’s literally all about flushing dcache lines of a set of pages. we folded the manual name in right here like a little name tag, because that header line does not need a solo moment. 💅

🌸 SYNOPSIS 🌸

       void drm_clflush_pages (struct page *pages[] , unsigned long num_pages
       );

🎀 ARGUMENTS 🎀

• pages — the list of pages to be flushed. that’s the lineup, bestie. 📋
• num_pages — the number of pages in the array. count ’em, don’t guess. 🔢

🦋 DESCRIPTION 🦋

so what it does: it flushes every data cache line entry that points to an address belonging to a page in the array. every single one that’s repping one of those pages gets the flush treatment. that’s the whole assignment. ✨
