+GLINT State Transition Strategy
+
+Direct Rendering requires a coordinated method of state management
+across all drivers accessing this device. This document defines the
+expected behavior of all drivers participating in direct rendering with
+this device.
+
+Currently only the GMX2000 supports direct rendering.
+
+
+Section 1) State Transition Types
+
+The direct rendering document entitled "state-mgmt.txt" gives a device
+independent overview on the different types of state transitions. This
+section gives a more detailed description of GLINT specific hardware state.
+
+No context switch--no state saves or restores will be done for transitions,
+however the device can be busy executing commands from previous accesses to
+the device.
+
+X context switch--the intersection of 2D and 3D state will be saved
+and restored. This is the state marked as DDX/3DClient in Appendix A.
+The device will be synced and idle after this switch.
+
+3D context switch--all 3D state will be saved and restored. 3D state is
+defined as all registered owned by the 3DClient driver. See Appendix A
+for more details. The device will be synced and idle after this switch.
+
+The registers owned by the DRM kernel module and submodules are not
+managed by context switches.
+
+
+Section 2) VT Switching and DGA Access
+
+VT Switching away from the X Server or client access to the device
+framebuffer via DGA require the device to be locked away from 3D direct
+rendering accesses. The X Server will hold the lock on behalf of these
+services until access is restored.
+
+
+Section 3) Potential Optimizations
+
+Lighten the number of registers required for context switches by using a
+mechanism to determine whether stipple or pattern registers need to be
+saved/restored. This optimization has not been done for the initial
+direct rendering infrastructure sample implementation.
+
+
+Appendix A: GMX2000 Register Ownership
+
+driver column contains:
+ DDX - DDX driver manages register
+ DRM - DRM or DRM subdriver manages register
+ 3DClient - 3D Client Driver manges register
+ DDX/3DClient, DDX/DRM, 3DClient/DRM - register access is shared
+
+if the RO (read only) column is marked with a *, then no writes are
+permitted to this register, and thus no drivers own it.
+
+primary and secondary columns contain the default values after
+initialization. primary is the master rasterizer, secondary is the
+slave rasterizer.
+
+
+Name offset primary secondary RO driver
