I fixed this by changing the default compression-algo to lzo via etc/config/ system. My intention was not to use an additional kernel-module which will consume additional RAM which I just won by using zram ...

My idea based on the fact, to have an easy way to disable certain kernel- features to reduce teh kernel-size (in flash and RAM). Candidates I see here are: USB-Support, additional filesystems, block-devices, ... Even some devices provide USB-connectors it might be better to have less OOM- crashes and reboots than installing a usb-flashdrive. In our Freifunk-Firmware I've seen much less runtime-problems with a stripped down kernel. With having the 8/32 in tiny it would just be a config-file for the low-RAM boards. Having them in generic subtarget would require to build 2 kernels for the same subtarget. > In it's current state, it will most likely increase low-memory issues as the > squashfs blocksize is 1024kB compared to the regular 256kB. Not that > ath79-tiny has no target-flag for small memory set. > Did you miss an "e" ? "Note that ath79-tiny has ..." gives more sense to me. Reading it this way, you expect the larger blocksize was choosen as tradeoff between using the flash most efficient vs. RAM for the 4/32 boards? I've seen there is a low_mem flag for some 16MB boards defined. It seems that for some config-options SMALL_FLASH and LOW-MEM are conflicting.

Kernel 4.19 support is still present in master (for regression testing), so we should properly implement the switches until it is removed entirely.

You're absolutely right, the lzo-rle is a separate module. Now, what I don't understand is why the crypto layer advertises lzo-rle support without the module being present. Sounds like an upstream bug to me… Thanks, Rui ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
zram-swap: default to lzo instead of lzo-rle compression
Hi, I think commit 419f149e482641ddc520f80a7ab2038f7e2ebc8a is not the proper fix for the described issue. The kernel module lzo-rle is still missing. To solve this, it must be installed on the root-fs: diff --git a/package/kernel/linux/modules/lib.mk b/package/kernel/linux/modules/lib.mk index 1289cc1f25..fade8a5cfd 100644 --- a/package/kernel/linux/modules/lib.mk +++ b/package/kernel/linux/modules/lib.mk @@ -109,9 +109,10 @@ define KernelPackage/lib-lzo HIDDEN:=1 FILES:= \ $(LINUX_DIR)/crypto/lzo.ko \ + $(LINUX_DIR)/crypto/lzo-rle.ko@ge5.1 \ $(LINUX_DIR)/lib/lzo/lzo_compress.ko \ $(LINUX_DIR)/lib/lzo/lzo_decompress.ko - AUTOLOAD:=$(call AutoProbe,lzo lzo_compress lzo_decompress) + AUTOLOAD:=$(call AutoProbe,lzo lzo-rle lzo_compress lzo_decompress) endef define KernelPackage/lib-lzo/description Since kernel 4.19 isn't longer used, @ge5.1 isn't necessary.
