** This issue should share same root cause with 939565 - Gralloc Allocation can take 25ms+ ; BenWa suggested to add a flag - MAP_POPULATE for mmap() calls. My experiments shows that does help for gralloc performance(from 25+ ms to about 19 ms). According BenWa's comment it might dues to mmap sets up the page lazily when the allocation is large. In this case we always memset the entire area so the pages fault-in because they aren't setup. Another reason that I am suspecting is the "write on demand" nature of linux kernel's memory management strategy. Diego just take the ownership of 939565 and will following up that issue. | ** This issue should share same root cause with 939565 - Gralloc Allocation can take 25ms+ ; BenWa suggested to add a flag - MAP_POPULATE for mmap() calls.
