Description Mathias Fröhlich 2009-10-17 00:13:00 UTC

Hi,

I have a problem with mesas teximage performance test on my r520.
The in kernel texture check fails because of both bit11 flags being set on 16x16 textures. It tuns out that these bits are still set and not cleared in the pp_txpitch field of the texture.
The attached patch at least helps for this case on my machine. It clears the bit 11 from the pitch field if the texture is smaller and masks out that hight bits on the conventional width and height field.

Not sure if this is the right fix, but that helps here and hopefully gives a clue what to fix.

thanks

Mathias

Thanks for looking into this, but it seems you forgot to actually attach the patch?
