Or current render target cache setting is to key on the binding table index, meaning the HW associates a number in the range [0, 7] to a RENDER_SURFACE_STATE description. If you want change the render target 0 between 2 draw calls, you need to insert a PIPE_CONTROL in between the 2 draw calls with pb-stall + rt-flush in order to flush an writes to a previous RENDER_SURFACE_STATE that has now becomed disassociated with the [0, 7] number. This PIPE_CONTROL taking care of the flush is dealt with in cmd_buffer_maybe_flush_rt_writes(). This function diffs the current BTI setup for render targets (first 0 to 7 BTIs) with what the next fragment shader wants. The issue here is we might have a render pass with 0 color attachments and yet in |

`Mesa <https://mesa3d.org>`_ - The 3D Graphics Library ====================================================== Source ------ This repository lives at https://gitlab.freedesktop.org/mesa/mesa. Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://docs.mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_): .. code-block:: sh $ meson setup build $ ninja -C build/ $ sudo ninja -C build/ install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary.
