I wouldn't say that 1G was too small currently as, for example, the cache for shader heavy DeusEx:MD is ~50M compressed per your commit message. There is the mythical quote of 640K being enough but how many games and applications do you need cached at once? A more relevant issue would then be the random eviction rather than using LRU eviction. However perhaps we could dynamically scale by checking statvfs and quotactl to choose MAX[1G, MIN[10% user home filesystem, 10% user home quota]]? -- Alan. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
