Hi, all expert,
I run one case on i.MX6q-sabresd board, and found page allocation failure, but the kernel dump show there have free memory, I don't know why does allocate page failed.
Any points or comment are appreciated.
The case:
- Board: imx6q sabresd board: 1G ddr memory
- Kernel version: 3.10.53, with CMA enabled
- After kernel up, nfs mount one streaming server, and then aplay the streaming in loop.
- After 1 hours test, kernel dump page allocation failure, but networking and system is active.
- i.MX6q networking driver: drivers/net/ethernet/freescale/fec_main.c
The dump log:

x800_24fps_1940kbps_a_44.1khz_96.5Kbps_2_Transformers2_h1080p.rmvb -rv9_ra6_1920
playbin is employed!

Starting a new thread is not very much helpful. Just for reference the
original thread was started here:
http://marc.info/?l=linux-mm&m=141777497709236
and CMA (or its configuration) as a potential culprit pointed at
http://marc.info/?l=linux-mm&m=141778416412151
I have suggested to contact CMA people. git log on mm/cma.c suggests:
Joonsoo Kim, Marek Szyprowski and Laurent Pinchart maybe there are
others. I am not familiar with CMA much myself.
So please reopen the original thread and add the relevant people into
the CC list. You can remove cgroups mailing list as this doesn't seem to
be related to the cgroups.

Hi, all expert,
I run one case on i.MX6q-sabresd board, and found page allocation failure, but the kernel dump show there have free memory, I don't know why does allocate page failed.
Any points or comment are appreciated.
The case:
- Kernel version: 3.10.53
- After kernel up, nfs mount one streaming server, and then aplay the streaming in loop.
- After 1 hours test, kernel dump page allocation failure, but networking and system is active.
- i.MX6q networking driver: drivers/net/ethernet/freescale/fec_main.c
The dump log:
root@imx6qdlsolo:/mnt/src/RVDec/1080#
x800_24fps_1940kbps_a_44.1khz_96.5Kbps_2_Transformers2_h1080p.rmvb -rv9_ra6_1920
