| * | mesa: Fix uf10_to_f32() scale factor in the E == 0 and M != 0 case. | Kenneth Graunke | 2016-08-17 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GL_EXT_packed_float, 2.1.B Unsigned 10-Bit Floating-Point Numbers: 0.0, if E == 0 and M == 0, 2^-14 * (M / 32), if E == 0 and M != 0, 2^(E-15) * (1 + M/32), if 0 < E < 31, INF, if E == 31 and M == 0, or NaN, if E == 31 and M != 0, In the second case (E == 0 and M != 0), we were multiplying the mantissa by 2^-20, when we should have been multiplying by 2^-19 (which is 2^(-14 + -5), or 2^-14 * 2^-5, or 2^-14 / 32). The previous section defines the formula for 11-bit numbers, which is: 2^-14 * (M / 64), if E == 0 and M != 0, In other words, we had accidentally copy and pasted the 11-bit code to the 10-bit case, and neglected to change the exponent. Fixes dEQP-GLES3.functional.pbo.renderbuffer.r11f_g11f_b10f_triangles when run with surface dimensions of 1536x1152 or 1920x1080.

| * | util/format: Use explicitly sized types | Jason Ekstrand | 2016-08-05 | 1 | -4/+6 |
| | | | | | | | | | | Both the rgb9e5 and r11g11b10 formats are defined based on how they are packed into a 32-bit integer. It makes sense that the functions that manipulate them take an explicitly sized type. Signed-off-by: Jason Ekstrand <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]> | ||||
