It has GPU scope. - "base": This channel is intended to be used for OpenGL SwapBuffers - flipping. There is one base channel per head. - "overlay": This channel is intended to be used for flipping the - overlay. There is one overlay channel per head. - "overlay immediate": This channel is intended to be used to position - the overlay within the raster of the head. There is one - overlay immediate channel per head. Originally, it was - conceived that a display driver would position the overlay - in response to a window move, using the "overlay immediate" - channel, and a video driver would flip buffers using the - overlay channel. - "cursor": This channel is used to position the cursor. There is - one cursor channel per head. The cursor format and buffer - is specified through the core channel. It was originally - conceived that the management of cursor would be distributed - between the core and cursor channels in the same way that - overlay management is distributed between overlay and overlay - immediate channels. The cursor channel allows low-latency - cursor position updates, asynchronously to the core channel. - -The "NVDisplay" Engine is new in Volta, and is a major improvement upon EVO. -The software interface consists of a set of channels as in EVO, but how those -channels can be used is more flexible. - - "core": This channel is similar to EVO's core channel, except it does not - support programming a surface as a base layer. - "window": This channel replaces EVO's base and overlay channels. It is - designed support a superset of the capabilities of the earlier - channels, but in addition supports scaling, alpha blending, and - blend order, among other improvements. Windows are not inherently - bound to a head and must be bound explicitly with core channel - methods. - "window immediate": Like EVO's overlay immediate, this can be used to - position the corresponding window channel on the raster. Unlike - EVO's overlay immediate, this is a DMA channel to support - enqueuing more than one update at a time. - "cursor": This is similar to EVO's cursor channel. There is one cursor - per head. - -There is a per-channel header file that defines the method interface to -each channel. - -There are both a "class name" and a software class number that are -used to describe the combination of channel versions used together. - -The table below describes which class name is used with which GPU, -and which channel header files are used with that class. - -__________________________________________________________________________ - -Class Name: DISP010X -Software Class Number: 5070 -Cursor Channel: cl507a.h -Overlay Immediate Channel: cl507b.h -Base Channel: cl507c.h -Core Channel: cl507d.h -Overlay Channel: cl507e.h -GPUs: nv50 -__________________________________________________________________________ - -Class Name: DISP011X -Software Class Number: 8270 -Cursor Channel: cl827a.h -Overlay Immediate Channel: cl827b.h -Base Channel: cl827c.h -Core Channel: cl827d.h -Overlay Channel: cl827e.h -GPUs: g84, g86, g92 -__________________________________________________________________________ - -Class Name: DISP012X -Software Class Number: 8370 -Cursor Channel: cl827a.h -Overlay Immediate Channel: cl827b.h -Base Channel: cl837c.h -Core Channel: cl837d.h -Overlay Channel: cl837e.h -GPUs: gt200 -__________________________________________________________________________ - -Class Name: DISP014X -Software Class Number: 8870 -Cursor Channel: cl827a.h -Overlay Immediate Channel: cl827b.h -Base Channel: cl837c.h -Core Channel: cl887d.h -Overlay Channel: cl837e.h -GPUs: g94, g96, g98, mcp7x -__________________________________________________________________________ - -Class Name: DISP015X -Software Class Number: 8570 -Cursor Channel: cl857a.h -Overlay Immediate Channel: cl857b.h -Base Channel: cl857c.h -Core Channel: cl857d.h -Overlay Channel: cl857e.h -GPUs: gt215, gt216, gt218, mcp89 - gf100, gf104, gf106, gf114, gf116, gf108 -__________________________________________________________________________ - -Class Name: DISP020X -Software Class Number: 9070 -Cursor Channel: cl907a.h -Overlay Immediate Channel: cl907b.h -Base Channel: cl907c.h -Core Channel: cl907d.h -Overlay Channel: cl907e.h -GPUs: gf119 -__________________________________________________________________________ - -Class Name: DISP021X -Software Class Number: 9170 -Cursor Channel: cl917a.h -Overlay Immediate Channel: cl917b.h -Base Channel: cl917c.h -Core Channel: cl917d.h -Overlay Channel: cl917e.h -GPUs: gk104, gk106, gk107 -__________________________________________________________________________ - -Class Name: DISP022X -Software Class Number: 9270 -Cursor Channel: cl917a.h -Overlay Immediate Channel: cl917b.h -Base Channel: cl927c.h -Core Channel: cl927d.h -Overlay Channel: cl917e.h -GPUs: gk110, gk208 -__________________________________________________________________________ - -Class Name: DISP024X -Software Class Number: 9470 -Cursor Channel: cl917a.h -Overlay Immediate Channel: cl917b.h -Base Channel: cl927c.h -Core Channel: cl947d.h -Overlay Channel: cl917e.h -GPUs: gm107, gm108 -__________________________________________________________________________ - -Class Name: DISP025X -Software Class Number: 9570 -Cursor Channel: cl917a.h -Overlay Immediate Channel: cl917b.h -Base Channel: cl927c.h -Core Channel: cl957d.h -Overlay Channel: cl917e.h -GPUs: gm200, gm204, gm206 -__________________________________________________________________________ - -Class Name: DISP027X -Software Class Number: 9770 -Cursor Channel: cl917a.h -Overlay Immediate Channel: cl917b.h -Base Channel: cl927c.h -Core Channel: cl977d.h -Overlay Channel: cl917e.h -GPUs: gp100 -__________________________________________________________________________ - -Class Name: DISP028X -Software Class Number: 9870 -Cursor Channel: cl917a.h -Overlay Immediate Channel: cl917b.h -Base Channel: cl927c.h -Core Channel: cl987d.h -Overlay Channel: cl917e.h -GPUs: gp102, gp104, gp106, gp107, gp108 -__________________________________________________________________________ - -Class Name: NVD_20 -Software Class Number: C370 -Cursor Channel: clc37a.h -Window Immediate Channel: clc37b.h -Core Channel: clc37d.h -Window Channel: clc37e.h -GPUs: gv100 -__________________________________________________________________________ - |
