Implement raspberry pi tiled texture

[marekkedzierski]

All, This is basic tiled textures support for T-texture type (page 105 from VC4 doc). It supports flags Indy mentioned (D3D10_DDI_USAGE_DEFAULT/ only D3D10_DDI_BIND_SHADER_RESOURCE). It renders both Dolphin and Cube in tests. All comments are welcome.

Cheers, Marek

Thanks Marek for the pull request!

It looks like the MSFT bot didn't automatically add a comment when it added the "cla-required" tag, so I'm adding the comment it would have posted here (you'll only need to do this once):

Hi, Marek:

Please let us know if the "notes" make sense.

@marekkedzierski, Thanks for signing the contribution license agreement so quickly! Actual humans will now validate the agreement and then evaluate the PR.
Thanks, MSBOT;

Indy, I did several fixes after your short review. I've accepted all your comments - they definitely make sense.

There is one place where I tweaked code only slightly - this is RosUmdResource, line 342. The values (32x32) are now hardcoded, but I've removed VC4_BINNING_TILE_PIXELS. I've not done table with precalculated values for various formats, because I don't wan't to make code too complex for basic tiled textures support. I will add 'real' values with handling of new pixel formats (those from issue #25). Or I will add them with handling various pixels format in general? What do you think? All comments are welcome.

Thanks!

Thanks a lot! I've not noticed that! However I've added support for various types of textures (32bpp, 16bpp, 8bpp). I did the commit under the same pull request. I'm sorry, I will move it to another task then. Thanks!
