Subject: [PATCH] drm/vc4: Don't force new binner overflow allocation per draw.
|
|
|
|
This came from the initial bringup code, which always idled the GPU
|
|
and always reset the overflow. That massively increases the size of
|
|
the working set when you're doing lots of small draws, though, as is
|
|
common on X desktops or piglit.
