drm_pagemap_get_devmem_page(9)

🎀 drm_pagemap_get_devmem_page(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for drm_pagemap_get_devmem_page(9). This is the one where we get a reference to a device memory page. Main character energy, lowkey. 💅

💖 NAME 💖

drm_pagemap_get_devmem_page — Get a reference to a device memory page ✨

🌸 SYNOPSIS 🌸

void drm_pagemap_get_devmem_page (struct page *page , unsigned int order
       , struct drm_pagemap_zdd *zdd );

🦋 ARGUMENTS 🦋

• page — Pointer to the page. literally the page we're talking about 🫶
• order — Order. yes bestie, that's the whole description, no cap 😭
• zdd — Pointer to the GPU SVM zone device data. the GPU SVM zone device data in question 💜

💀 DESCRIPTION 💀

okay so here's the vibe: this function associates the given page with the specified GPU SVM zone device data, and initializes it for zone device usage. That's the whole glow-up. ✨
