💖 vmw_cmd_readback_gb_image(9) 💖

okay so bestie, you’re on the vmw_cmd_readback_gb_image(9) page in the Kernel API Manual, and it’s giving very specific validation realness ✨. This page is all about validating the SVGA_3D_CMD_READBACK_GB_IMAGE command — that’s the whole vibe, no cap. Let’s go 🫶.

🌸 NAME 🌸

vmw_cmd_readback_gb_image — Validate SVGA_3D_CMD_READBACK_GB_IMAGE command

✨ SYNOPSIS ✨

int vmw_cmd_readback_gb_image (struct vmw_private *dev_priv , struct
       vmw_sw_context *sw_context , SVGA3dCmdHeader *header );

🎀 ARGUMENTS 🎀

• dev_priv — pointer to a device private struct. Your device-private pointer, bestie 💅.
• sw_context — the software context being used for this batch. It’s the software context on batch duty for this call.
• header — pointer to the command header in the command stream. That’s the command header in the command stream, pointed at.
