memory overflow android5.1 BSP linux 3.14.52

[ifzhao]

Hi all, as you can see here, gfp_mask=0x4d0 order=2 which means 2^2 pages of ___GFP_REPEAT ___GFP_FS ___GFP_IO ___GFP_WAIT is requiredhere. However MMU do not have enough pages, then OOM occurs.

Also, zone of both normal and highmem reserve enough memory, and do not trigger the watermark here.

Hi If

had you tried latest android bsps with L4.15 kernel on

http://www.nxp.com/products/software-and-tools/software-development-tools/i.mx-software-and-tools/i....

Had you tried Demo Images on that link.

Best regards
igor

I tried demo images, it turns out the same problem.
