https://bugs.freedesktop.org/show_bug.cgi?id=105095 --- Comment #2 from Roland Scheidegger --- FWIW this looks very similar to a bug recently fixed for radv. Probably not so coincidentally, radeonsi has workarounds for 2/10/10/10 signed formats, apparently gcn hw before vega (with the exception of stoney ridge) has a bug interpreting the 2bit alpha as unsigned. The output from this test would be consistent with that (alpha 1.0 as 2 bit snorm would be 0x01, whereas that value interpreted as unorm would be 0.333). So maybe the same bug could affect later evergreen hw as well. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=105095 --- Comment #1 from Roland Scheidegger --- Is that BARTS specific? My piglit runs with Juniper (HD 5750) show this test passing (and generally there's no difference in the driver between these two chips). (Albeit I never ran it with this specific mesa version, you could try mesa git.) -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

And i think 2.2 / 2.3 equation isn't causing this bug, because from what i see zero is represented correctly in stk, also some amd devs told me barts switched to use the new formula long time ago. Any idea? -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
