           Summary: gallium: transfers should not use z/depth and not
                    y/height for 1d array textures as layer parameter
           Product: Mesa
           Version: git
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
        AssignedTo: mesa-dev at lists.freedesktop.org
        ReportedBy: sroland at vmware.com


Currently, gallium is using gl-style y/height for the layer parameter for 1d
array textures in pipe transfers (that is, it is using the next "unused"
parameter, which is y for 1d array, and z for 2d array textures).
This was never meant to be that way but not properly documented. It should
always use z/depth for layer parameter, regardless if it's a 1d or 2d array
texture.
Conceptually, it is a different parameter, which is just basically merged with
z/depth since 3d arrays don't exist.
