Guides¶

Tutorial-style walkthroughs for each major subsystem of opengnm. These guides focus on how to use the API in practice, with code examples and explanations of the underlying concepts.

Guide List¶

Guide	Topics
Rendering Pipeline	VideoOut setup, command buffer, draw, submit, flip
Textures & Formats	GnmDataFormat, GnmTexture, tiling, BC compression
Render Targets	Color RT + Depth RT setup, sizing, alignment
Shaders	Shader binary format, stage registers, fetch shaders
Command Buffers	GnmCommandBuffer + DrawCmd building, PM4 packets
Surface Computation	sceGpa* / AddrLib: surface info, tiling, decompression

Prerequisites¶

All guides assume you have built and installed opengnm. See Getting Started for build instructions.

Including the API¶

#include <gnm.h>  // Master include — pulls in everything

Or include individual headers as needed:

#include <gnm_types.h>
#include <gnm_drawcommandbuffer.h>
#include <gnmdriver.h>
#include <gpuaddr.h>
#include <gnm_helpers.h>
