From 8a2dfa16917aca821caf1a1d9b53faa3b025656c Mon Sep 17 00:00:00 2001 From: Robert Yang Date: Mon, 25 Jan 2016 00:45:59 -0800 Subject: image.bbclass: check INITRAMFS_MAXSIZE Usually, the initramfs' maxsize can be 1/2 of ram size since modern kernel uses tmpfs as initramfs by dafault, and tmpfs allocates 1/2 of ram by default at boot time, which will be used to locate the initramfs. Set INITRAMFS_MAXSIZE to 131072K (128M) by default (ram 256M), the initramfs is small usually, for example, core-image-minimal-initramfs is about 21M (uncompressed, 17M * 1.3) by default, but if the user add a lot pkgs to initramfs, we can error and stop to let the user know ealier rather than fail to boot (e.g., OOM-killer) at boot time.
