GPU Textures

2015-05-11T22:48:39Z

ILOVEPIE: /* Texture color types */ added name for texture format 0x6

This page describes the [[GPU_Commands|GPU commands]] used for textures.

== General information ==
Individual texels in a texture are laid out in memory as a [http://en.wikipedia.org/wiki/Z-order_curve Z-order curve].

== Texture unit setup: Register 0x80 ==
Register 0x80 is used to enable individual texture units.

{| class="wikitable" border="1"
! Bit
! Description
|-
| 0
| Enable texture unit 0.
|-
| 1
| Enable texture unit 1.
|-
| 2
| Enable texture unit 2.
|}

== Configuration of texture unit 0 ==

! Register ID
! Description
|-
| 0x0081
| Border color (unverified)
|-
| 0x0082
| Bits 16-31 are the texture width. Bits 0-15 are the texture height. The maximum texture size in either direction is 1024.
|-
| 0x0083
| Texture parameters (filtering, wrapping), see below.
|-
| 0x0084
| LOD setup?
|-
| 0x0085
| Physical address of texture data (divided by 8).
|-
| 0x0086
| Physical address of texture data for cube mapping?

| Physical address of texture data for cube mapping?
|-
| 0x0088
| Physical address of texture data for cube mapping?

|-
| 0x008B
| Shadow related?
|-
| 0x008E
| Texture format (see below)
|}

== Configuration of texture units 1 and 2 ==
Texture units 1 and 2 use a configuration block similar to the one of texture unit 0. They are based at registers 0x0091 and 0x0099.

{| class="wikitable" border="1"
! Index word
! Description
|-
| 0-4
| Same as for texture unit 0
|-

| Texture format (see below)
|}

== Configuration of texture unit 3 ==
The configuration block for texture unit 3 seems to be vastly different from the other texture units. Instead, registers 0x00A8 through 0x00B7 are used to configure procedural texturing features.

== Texture parameters ==

Homebrew Applications

ILOVEPIE: /* List */ added the homebrew launcher

==Installing==
Applications are installed by copying the necessary files to the 3ds/ folder in the root of the SD-card. Most applications come with two files:
* boot.3dsx: The executable.
* icon.bin: The icon/metadata.

The [[Homebrew Launcher]] will scan the sdcard for all .3dsx files, but will only display an icon for those who have one according to the format described above.

MVD Services

2014-12-11T22:37:12Z

ILOVEPIE: missed an edit

This is for using the MVD hardware video decoder(unknown whether MVD can do more than decoding) + hardware color-format converter. The [[New_3DS]] [[Internet Browser]] uses mvd:STD for video decoding + YUV2RGB for decoded MJPEG frames.

See [[Internet_Browser|here]] for the supported hardware decoder video codecs.

A maximum of 4 sessions can be opened at a time, for all of these services combined.

|}

This one uses the I/O mapped @ 0x10207000.

This service is used by the [[New_3DS]] [[Internet Browser]].

By default MVD does(?) various post-processing with the output image, this is controlled by the [[MVDSTD:GetConfig|configuration]]. This post-processing isn't done at all in certain cases. By default MVD will align the output frame width to 512, by writing zero-value pixels.

Initialization procedures:
* MJPEG: Use command [[MVDSTD:Initialize]] with bufsize=1, then command 0x00180000.
* H.264: If needed, use [[MVDSTD:CalculateWorkBufSize]]. Then use [[MVDSTD:Initialize]]. Then use commands 0x00050100, 0x00180000, and 0x001B0040. Then use [[MVDSTD:DecodeFrame]] 3 times with unknown input data. Use command 0x000A0000, then use [[MVDSTD:DecodeFrame]] with unknown data.

Shutdown procedures:
* MJPEG: just use command 0x00190000, then [[MVDSTD:Shutdown]].
* H.264: Use command 0x00090042 in a loop, waiting for it to return a retval that isn't 0x00017002. Then use commands 0x001C0000, 0x00190000, and 0x00070000. Then use [[MVDSTD:Shutdown]].

==MVD Service "l2b:u"==
This one uses the I/O mapped @ 0x10130000.

==MVD Service "l2b2:u"==
This uses the same command-handler as "l2b:u".

==MVD Service "y2r2:u"==
This one uses the I/O mapped @ 0x10102000.

MVD Services

2014-12-11T20:21:39Z

ILOVEPIE: added h.264 profile and level compatability chart

This is for using the MVD hardware video decoder(unknown whether MVD can do more than decoding) + hardware color-format converter. The [[New_3DS]] [[Internet Browser]] uses mvd:STD for video decoding + YUV2RGB for decoded MJPEG frames.

See [[Internet_Browser|here]] for the supported hardware decoder video codecs.

A maximum of 4 sessions can be opened at a time, for all of these services combined.

==MVD Service "mvd:STD"==

|
| [[MVDSTD:GetConfig|GetConfig]]
|-
| 0x001E0044
|
| [[MVDSTD:SetConfig|SetConfig]]
|}

This one uses the I/O mapped @ 0x10207000.

This service is used by the [[New_3DS]] [[Internet Browser]].

By default MVD does(?) various post-processing with the output image, this is controlled by the [[MVDSTD:GetConfig|configuration]]. This post-processing isn't done at all in certain cases. By default MVD will align the output frame width to 512, by writing zero-value pixels.

Initialization procedures:
* MJPEG: Use command [[MVDSTD:Initialize]] with bufsize=1, then command 0x00180000.
* H.264: If needed, use [[MVDSTD:CalculateWorkBufSize]]. Then use [[MVDSTD:Initialize]]. Then use commands 0x00050100, 0x00180000, and 0x001B0040. Then use [[MVDSTD:DecodeFrame]] 3 times with unknown input data. Use command 0x000A0000, then use [[MVDSTD:DecodeFrame]] with unknown data.

Shutdown procedures:
* MJPEG: just use command 0x00190000, then [[MVDSTD:Shutdown]].
* H.264: Use command 0x00090042 in a loop, waiting for it to return a retval that isn't 0x00017002. Then use commands 0x001C0000, 0x00190000, and 0x00070000. Then use [[MVDSTD:Shutdown]].

==MVD Service "l2b:u"==
This one uses the I/O mapped @ 0x10130000.

==MVD Service "l2b2:u"==
This uses the same command-handler as "l2b:u".

==MVD Service "y2r2:u"==
This one uses the I/O mapped @ 0x10102000.
