…e. (pytorch#15110) Summary: ### Summary This diff improves the overall performance of the linear shader by removing manual unrolling in the `linear_qcsnw_tiled.glsl` file. The changes include: - Removing the `[[unroll]]` directive in the for loop to allow the compiler to automatically unroll the loop, which can lead to better performance. - Changing the type of `mat1` from `VEC4_T[TILE_ROWS]` to `T[TILE_ROWS][4]` to better match the access pattern in the loop.
