vmw_stdu_plane_update_bo(9)

💖 NAME 💖

okay so bestie, welcome to vmw_stdu_plane_update_bo(9) from the Kernel API Manual 💅✨. The tea is literally this: update display unit for bo backed fb. That's the whole name vibe, no cap. It's giving kernel display-unit realness, and if you're poking around vmwgfx, iykyk. This function is main character energy fr.

✨ SYNOPSIS ✨

here's the signature, fr fr — the way that every character has to stay exactly where it is is iconic:

int vmw_stdu_plane_update_bo (struct vmw_private *dev_priv , struct drm_plane *plane , struct drm_plane_state *old_state , struct vmw_framebuffer *vfb , struct vmw_fence_obj **out_fence );

🎀 ARGUMENTS 🎀

okay the cast of characters, one by one, no skipping:

• dev_priv — device private. 💖
• plane — plane state. ✨
• old_state — old plane state. 🎀
• vfb — framebuffer which is blitted to display unit. 🦋
• out_fence — If non-NULL, will return a ref-counted pointer to vmw_fence_obj. The returned fence pointer may be NULL in which case the device has already synchronized. 💅

💅 RETURN 💅

vibe check: 0 on success or a negative error code on failure. periodt. 💀✨
