Hi All, I'm using TI Jacinto 6 based custom board with 1G RAM (similar to dra7-evm), running Android based on TI 6AL.1.0 Release (http://omappedia.org/wiki/6AL.1.0_Release_Notes) and kernel 3.14, with hibernate support based on the following patches: https://git.linaro.org/people/grygorii.strashko/p-ti-linux-3.14.y-android-hib.git branch: p-ti-linux-3.14.y-android-hib-dra7 Swap partition is placed on eMMC, size is 2G Following commands used to run hibernate (hibernate.sh script): swapon /dev/block/platform/44000000.ocp/by-name/swap sync echo 3 > /proc/sys/vm/drop_caches echo 536870912 > /sys/power/image_size echo disk > /sys/power/state swapoff /dev/block/platform/44000000.ocp/by-name/swap The system successfully goes to hibernate state if no apps are runing (MemFree: 603268 kB), but fails to go to hibernate if custom app is runing (MemFree: 437036 kB, see Log 1 below). The problem is in the hibernate_preallocate_memory() (kernel/power/snapshot.c). It calculates free pages count and this count is enough to store hibernate image, but later preallocate_image_pages failes to allocate enough pages. As result swsusp_save() failed later with [ 197.368434] sh: page allocation failure: order:0, mode:0x120 The system with custom app running will go to the hibernation state successfully if hibernate.sh runs 3 times. I found 2 solutions to avoid this issue: 1. call shrink_all_memory() few times if preallocate_image_x() can't allocate requested number of pages (see Diff 1 below). 2. Add __GFP_MOVABLE flag to GFP_IMAGE. Seems it allows to use memory, reserved for CMA memory pools (see Diff 2 and Log 2 below). Could anybody confirm these solutions are reliable? Is there any different/better solutions? Thanks in advance. Log 1 was taken with some additional debug output (see Diff 3 below). size += page_key_additional_pages(saveable); @@ -1368,8 +1379,22 @@ int hibernate_preallocate_memory(void) * the image and we're done. */ if (size >= saveable) { + +printk(KERN_INFO "\n====== mem info 2 begin ======\n"); +show_mem(0); +printk(KERN_INFO "\n====== mem info 2 end ======\n"); + pages = preallocate_image_highmem(save_highmem); + +printk(KERN_INFO "\n====== mem info 3 begin ======\n"); +show_mem(0); +printk(KERN_INFO "\n====== mem info 3 end ======\n"); + pages += preallocate_image_memory(saveable - pages, avail_normal); + +printk(KERN_INFO "\n====== mem info 4 begin ======\n"); +show_mem(0); +printk(KERN_INFO "\n====== mem info 4 end ======\n"); goto out; } === Diff 3 end =============== === Log 1 begin ================ # hibernate.sh [ 193.604814] Adding 2097148k swap on /dev/block/platform/44000000.ocp/by-name/swap.
