Chris Wilson 66df1014ef drm/i915: Keep a small stash of preallocated WC pages ... We use WC pages for coherent writes into the ppGTT on !llc architectures. However, to create a WC page requires a stop_machine(), i.e. is very slow. To compensate we currently keep a per-vm cache of recently freed pages, but we still see the slow startup of new contexts. We can amoritize that cost slightly by allocating WC pages in small batches (PAGEVEC_SIZE == 14) and since creating a WC page implies a stop_machine() there is no penalty for keeping that stash global.
