2010-10-05	r300g: fix microtiling for 16-bits-per-channel formats	Marek Olšák
	These texture formats (like R16G16B16A16_UNORM) were untested until now because st/mesa doesn't use them. I am testing this with a hacked st/mesa here.
2010-09-28	r300g: add support for 3D NPOT textures without mipmapping	Marek Olšák
	The driver actually creates a 3D texture aligned to POT and does all the magic with texture coordinates in the fragment shader. It first emulates REPEAT and MIRRORED wrap modes in the fragment shader to get the coordinates into the range [0, 1]. (already done for 2D NPOT) Then it scales them to get the coordinates of the NPOT subtexture. NPOT textures are now less of a lie and we can at least display something meaningful even for the 3D ones. Supported wrap modes: - REPEAT - MIRRORED_REPEAT - CLAMP_TO_EDGE (NEAREST filtering only) - MIRROR_CLAMP_TO_EDGE (NEAREST filtering only) - The behavior of other CLAMP modes is undefined on borders, but they usually give results very close to CLAMP_TO_EDGE with mirroring working perfectly. This fixes: - piglit/fbo-3d - piglit/tex3d-npot
2010-09-26	r300g: fix macrotiling on R350	Marek Olšák
	MACRO_SWITCH on R350 appears to use the RV350 mode by default. Who knew? NOTE: This is a candidate for the 7.9 branch.
2010-09-24	r300g: fix a copy-paste typo for logging	Marek Olšák

2010-09-13	r300g: add new debug options for dumping scissor regs and disabling CBZB clear	Marek Olšák

2010-08-20	gallium: make all checks for PIPE_TEXTURE_2D check for PIPE_TEXTURE_RECT too	Luca Barbieri
	Searched for them with: git grep -E '[!=]=.PIPE_TEXTURE_2D\|PIPE_TEXTURE_2D.[!=]=\|case.*PIPE_TEXTURE_2D' Behavior hasn't been changed.
2010-08-01	r300g: fix microtiling on RS6xx	Marek Olšák
	Getting tiling right has always been tricky. There are so many subtle details...
2010-07-25	r300g: make sure a texture is large enough for the CBZB clear	Marek Olšák
	The number of macrotiles in the Y direction must be even, otherwise memory corruption may happen (e.g. broken fonts). Basically, if we get a buffer in resource_from_handle, we can determine from the buffer size whether it's safe to use the CBZB clear or not.
2010-07-25	r300g: do not use TXPITCH_EN if the width is POT and the height is NPOT	Marek Olšák

2010-07-25	r300g: do not use TXPITCH_EN for power-of-two textures from the DDX	Marek Olšák
	We were using TXPITCH_EN for textures from the DDX since ever, for nothing.
2010-07-25	r300g: cleanup texture creation code	Marek Olšák
	This decouples initializing a texture layout/miptree description from an actual texture creation, it also partially unifies texture_create and texture_from_handle. r300_texture inherits r300_texture_desc, which inherits u_resource. The CBZB clear criteria are moved to r300_texture_desc::cbzb_allowed[level]. And other minor cleanups.
