This exists due to historical limitations which have long gone obsolete. This persists longer due to hostorical perf issues that have recently gone obsolete on the platforms shipping Venus. Meanwhile, clients like skiavk and ANGLE nowadays do a better job managing suballocations. The tiny perf win from having this giant internal pool has been beaten by the memory waste, longer one-shot jank due to largier alloc, allocations no need to be mapped but only because host-visible is advertised across mem types and varies workarounds and markups needed to make alignment work and make VVL happy. Dropping it also reduces the maintenance cost. Signed-off-by: Yiwei Zhang <zzyiwei@chromium.org> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/29362>
