Yes, yes it should, that's what I intended.

Could you paste or email me the results of: "sfdisk -lnd" please? - It's probably just a dodgy regex. The bugtracker link is right there on the package listing though...

You guys should read the thread; SwapSet automatically sets a ramzcache with size=65 mb and searches for swap partitions on your SD, and loads (swapon) these and prioritizes the swap settings.

Keep in mind that devs are still trying to find the best settings for using the swap-to-SD solution. The settings from vi_'s comments are recommended for just ramzcache.

I did a reboot, and now it correctly recognized the swap space in mmcblk1p2 and swapon'ed it as priority -2.

The reason may be, that before I had made "mkswap" on Linux PC, but now I redid "mkswap" on N900. So there may have been some incompatible parameters before and swapset failed to recognize it.

Re: [ANNOUNCE] COMPCACHE on kernel-power (now with notifications)
 

Hi,

i am testing this with different settings and have question about how to be sure if the lag is due to compache reaching its max size or if the lag is related to a CPU bottleneck.

What i mean is, if i set disksize with 64mb, to reach the max size, i have to load few apps, but if i set the disksize to 96 or 128MB, to reach the max size i have to load more apps.
As i usually use video+psx emulator+youtube when testing 131MB, i wonder if the lag is due to CPU overload.

Because, even if i experience some lags, it is very minimal.

Any advice woudl be very appreciated.

And thanks for this, again, awesome improvement.

Okay, so forget my last comment.
After a couple of hours, i faced the real lag/freeze. now i don't wonder anymore about this ;)

Getting the following error in dmesg after certain amount of usage with both 64MB ramzswap and swap on SD enable. Also, happens when using only SD as swap.

UBIFS is the file system on rootfs, isn't it? That should have nothing to do with ramzswap or µSD swapping.

Re: [ANNOUNCE] COMPCACHE on kernel-power (now with notifications)
 

I am well aware, but prior to using compcache, I never faced such an error in 2 years.

Re: [ANNOUNCE] COMPCACHE on kernel-power (now with notifications)
 

1) How much rootfs space have you got available? My first guess was that it might be getting low.
2) Are you quite sure this stops happening when you stop using compcache or µSD?
3) Which way do you start up the use of compcache/µSD now?

Re: [ANNOUNCE] COMPCACHE on kernel-power (now with notifications)
 

It may be related to UBIFS characteristic - remember, UBIFS is very prone to filesystem corruption (basically, undestroyable, at least, when comared to journaling ones), and memory is constantly used for operations on files, before they're written to actual filesystem.

Of course it's just assumption, but I think that patlak might find something useful, to determine why compcache performs so poorly on N900.
