[Mesa-dev] [PATCH 3/6] llvmpipe: allocate regular texture memory upfront

[sroland at vmware.com]

From: Roland Scheidegger <sroland at vmware.com>

The deferred allocation doesn't really make much sense anymore, since we no
longer allocate swizzled/linear memory in chunks and not per level / slice
neither.
This means we could fail resource creation a bit more (could already fail in
theory anyway) but should not fail maps later (right now, callers can't deal
with neither really).
