On GFX8+, there is a bug that affects TC-compatible depth surfaces when the ZRange is not reset after LateZ kills pixels. The workaround is to always set DB_Z_INFO.ZRANGE_PRECISION to match the last fast clear value. Because the value is set to 1 by default, we only need to update it when clearing Z to 0.0. We also need to set the depth clear regs and to update ZRANGE_PRECISION when initializing a TC-compat depth image to 0. Original patch from James Legg. This fixes random CTS fails with dEQP-VK.renderpass.suballocation.formats.d32_sfloat_s8_uint.input.* Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105396 CC: <mesa-stable@lists.freedesktop.org> Signed-off-by: Samuel Pitoiset <samuel.pitoiset@gmail.com> Reviewed-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl>
