Previously the address space went from 16M to ~0u, but with the refactor one of the 'f's was dropped, limiting us to 256MB. Additionally, the new interface takes a start and size, not start and end, so we can't just copy and paste.
Fixes regressions in dEQP-VK.memory.allocation.random.*
Fixes: ccac7ce373c1 ("drm/msm: Refactor address space initialization") Signed-off-by: Eric Anholt eric@anholt.net
rebased on https://patchwork.freedesktop.org/series/78281/ (which fixed half of the problem) and pushed this and 2/2 to msm-next so it should show up in linux-next shortly..
planning to wait a short time more to see if we find any other issues and then send a -fixes PR
I'll fix up the rest of the flubbed addresses sizes.
