STRUCT VMW_STDU_DIRTY(9)

Okay bestie, welcome to struct vmw_stdu_dirty(9) — yes, this is the Kernel API Manual, and this page is all about a closure structure for the update functions. It’s giving very specific struct energy, and we’re gonna keep every detail, no cap. 💅✨

💖 NAME 💖

struct vmw_stdu_dirty — closure structure for the update functions. That’s the whole name vibe, and it’s iconic for exactly what it says. 🎀

✨ SYNOPSIS ✨

Here’s the struct in all its curly-brace glory — copy it exactly, bestie:

       struct vmw_stdu_dirty {
           struct vmw_kms_dirty base;
           s32 left, right, top, bottom;
           s32 fb_left, fb_top;
           u32 pitch;
           union {
             struct vmw_bo *buf;
             u32 sid;
           };
        };

🎀 Members 🎀

Member-by-member vibe check, with every detail staying exactly where it belongs:

• base — The base type we derive from. Used by vmw_kms_helper_dirty.
• left — Left side of bounding box.
• right — Right side of bounding box.
• top — Top side of bounding box.
• bottom — Bottom side of bounding box.
• fb_left — Left side of the framebuffer/content bounding box
• fb_top — Top of the framebuffer/content bounding box
• pitch — framebuffer pitch (stride)
• {unnamed_union} — anonymous
• buf — buffer object when DMA-ing between buffer and screen targets.
• sid — Surface ID when copying between surface and screen targets.
