panfrost: Allocate polygon lists on-demand
Rather than alloacting a huge (64MB) polygon list on context creation and sharing it across framebuffers, we instead allocate polygon lists as BOs (which consistently hit the cache) sized appropriately; for about a month, we've known how to calculate the polygon list size so this has only recently become possible. The good news is we can render to truly massive framebuffers without crashing and, more importantly, we eliminate the 64MB upfront overhead. If a list that size isn't actually needed, it's not allocated. Signed-off-by: Alyssa Rosenzweig <[email protected]> Signed-off-by: Boris Brezillon <[email protected]>
