Re: [Announce] kernel-power stable v51 in Extras-Devel
 

wondered if you guys seen this. new patch for zswap (not compcache or zram)

http://www.phoronix.com/scan.php?pag...tem&px=MTI1MDM

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

N900 has 128mb ram only which makes swapping one of most important bottlenecks. It's a bit too low memory for fully using potential of zram, but zswap would be best solve of the problem.
Pali please support this ASAP... Could it come in kp52?

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

256MB of RAM.
Also, this should help a bit, as most of the bottleneck on the N900 comes from slow MMC access and puny CPU, the latter thankfully slightly alleviated by CSSU Thumb.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Actually it is 256MB.

I might look at the code these days, but don't hold your breath, there is more important stuff to come with CSSU, that will make things much better on memory/swap front - fixed severe memory leaks in 3 systemui plugins.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

thank U for reponse.. But it says incomptible package! And i can't install it.. ??

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Who/what says "incompatible package". I don't think I've ever seen such a message on my N900.

Please post the exact output of what happens when you install the packages with dpkg.

You are using dpkg aren't you?

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

It seems he's using a file explorer which is launching HAM.

If there will be no problem, I will push this version to Extras.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

The only thing i noticed was that i had to re-pair N900 with Carkit. No connection was possible otherwise.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

of course i'm using dpkg, don't panic boy! But when i installed via terminal, i couldn't boot my phone and reflashed again. Any of your brillant idea??

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

have u install with the right order?? kernel-power-flasher must be install last.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Please install in this order
kernel-power
kernel-power modules
kernel-power flasher
kernel-power bootimg

correct me if I am wrong

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Here are two oopslogs and the telepathy-ring core dump (can someone please forward it?) which (supposedly) led to them. I was on the street and was gonna receive sms and a phone call. Looks like they came simultaneously, maybe that's the problem. Or maybe it just turned off because it was cold, -10°C at most. But it booted afterwards.

Edit: attaching mtd2 on freemangordon's request.

kernel-config: http://pastebin.com/q8ye84aa

Edit 2: Bug tracker is readonly.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Another two reboots in one day. This time reports extended with the syslog. I hope it doesn't contain any confidential info (looks like it includes GSM CellIDs, but it's just from the first glance, didn't have time to check). The second one is not kernel oops but reboot-32wd_to crash 0_o. Maybe it's hardware failures, after all? :(

At 22:22 I just closed Marble which was the only opened application. And at 00:32 IIRC I was playing with dpkg -S / dpkg -L / fileorphan.sh in terminal + a couple of windows in the background.

Edit: checking syslog, it looks like nothing there:

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

of course. except for the flasher, i tried all the others. but it said shortly ''kernel-power-flasher first'' and i tried to install flasher, but then it said ''incompatible package''. don't understand why but this is the error that i got :(
sorry for my bad english, cause i can speak turkish and french...

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

when the Kernel-power version v51 (r1) push into extras.. :)

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

I am not certain but from what I have read here it won't.
KP52 will be the next "extras" KP after it has past QA.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

So, I reflashed. But after installing part of packages reboots continue. The first and yet only thing that crashed besides system rebooting is drlaunch widget and maybe hildon-desktop with it, but none of this triggered a core-dump creation, thus not really a crash. It just wiped all desktop widgets. It happened right after setting icon size to 60px, grid size to 8x4 and margins to 0. Also, I've changed transitions.ini radically in the same day before. Attached the oopses, dpkg selections, transitions.ini, drlaunch config.

Also, I have -devel enabled and I've done apt-get upgrade...

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Anyone else having sudden reboots?

How much does power consumtion change during WiFi authentication compared to the state right before? I was able to reproduce sudden reboot at will finally. By connecting/disconnecting to WiFi ~6 times in a row. Also it was at ~15% charge, maybe it's the battery failing. Right now I can't reproduce it and it's fully charged.

Also I've uninstalled drlaunch and changed transitions.ini less radically, only decreasing durations to 30.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

I might have observed something similar.... at least three times the device was turned off when it shouldn't. Last time (around 2am) it was fully charged, and in the morning wouldn't turn on again because the battery seemed empty.

Then i charged it to ~64%; maybe 2hrs later percentage already dropped to 48% almost without usage.

I'll see if i can get anything in observations. For now, it seems better...

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Yes, just reproduced it two times after phone was laying connected for several hours and discharged to <50%. I'm using ConnectNow widget to control the connection. AP is hidden, WPA2, dir-300 router.

So, can anyone else try reconnecting multiple times in a row with a discharged battery? I've also had it rebooted while connecting to GPRS, that's why I'm suggesting a power issue. Also, icd2 crash.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

A failing battery can cause brownouts, and they can eventually cause crashes that make the N900 reboot - try changing batteries to see if it helps.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Are you on kpv52 ?
If yes me experiencing same battery drain
tried powertop but nothing useful
now the only solution I got is to revert back to kpv51rc1
there is no battery drain till now
everything alright

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Hi,
i recently reflashed my rootfs and kernel and installed the cssu.
since then i could not fcam-drivers to work.
The camera works fine without the fcam-drivers.
But after installing fcam-drivers there is no image (its black) and in dmesg i see the line:

isp_mod: disagrees about version of symbol struct_module

when i do "modprobe fcam". I tried the fcam-drivers from extras, devel and the latest from the garage pages download, all with the same result. I also did a reboot after each installtion and took the battery out. Now i am running out of ideas...
Kernel is 2.6.28-10power51r1 and i am careful with reflashes as i lost my usb-port recently, mechanically :-(
Does anyone have a idea where i go wrong as there seems to be users who have the combination working?

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Just tried camera on kernel power v52 and I have the problem, but bless900 is working fine and I prefer bless900 anyway.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

I have a problem with BME Replacement, probably specifically with userspace daemon hald-addon-bme.

If the Kernel-CSSU install, it correctly displays the battery charge (from 0 to 100%), but it does not correct working LED - constantly orange light (not blinking) when charging, and constantly green light when fully charged, on even after disconnecting from the charger. If restart mce - LED work correctly.

If the Kernel-Power52 install, the LED is working correctly, but the total charge is shown from 107 to 112%! And full capacity of battery show less then with Kernel-CSSU (~1200-1250 mAh vs 1348 mAh), but battery charging to the value of Kernel-CSSU, as result - 1348/1224 = 110%.

Battery Widget 0.5 also show this value.

Also one bug with any kernel - sometimes at USB-connection with PC N900 not charging.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

I see there's a new version of the zswap module
http://lkml.indiana.edu/hypermail/li...1.0/02285.html
As ppl already said ...this should be included in kp... and maybe even become default in cssu.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Plz Help I want Remove Kernel Power 52 and Install 51 So plz suggest me how to do.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

From first page:
Uninstalling kernel image is possible only via menu entry "Nokia Kernel".

There is no way to direct downgrade... You need to get stock kernel first and then upgrade to kp51 again.

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

I dig up this thread http://talk.maemo.org/showthread.php?t=70082 about kernel-2.6.37, but didn't fully understand is that (="meego-kernel") booted and used with other Maemo5 components. And why kernel-power is (still) based on 2.6.28?


I'm also thinking what are the reasons today to not use (let say) kernel 3.8-rc3 (2013-01-10) on Maemo5/N900?

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

SGX driver?

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

@saponga
thank you, while uninstalling it showed some error so i manually downloaded those debs and installed, thank for reply :)

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

* maemo specified kernel interfaces
* missing kernel drivers
* changed interface of kernel <--> userpace drivers
* worse power management in some parts

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

Or better said "missing"

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

@freemangordon, @pali: If you think I'm nagging we can stop this, I'm not targeting your ignore-list :)

This is not mandatory. No doubt it is cool to have 3D. And there are little bit ironing left on non-3D hildon-desktop. And [/optimist] couple of years and we will have open source SGX: http://powervr.gnu.org.ve/doku.php [/optimist]

Is there more info about this topic than:
http://talk.maemo.org/showpost.php?p...4&postcount=37
Seems there are work to do, but which is show-stopper?

Seems much of them are merged to the mainline: http://elektranox.org/n900/kernel/status.html
What is still show-stopper?

Why is this? Is newer kernel written poorly?

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

for sgx, is N9 Meego build feasible if appropriate userland (glibc etc) are available?

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

@AapoRantalainen - my ignore list :eek: ? Why is that :)

If we want to make a progress, not regress, there should be 3D acceleration. IMO.

The point is that without drastically modifying the vanilla, we'll hit newer sysfs interfaces, closed parts in fremantle and whatnot.

I wonder what exactly benefit do you expect from 3.8 on n900?

See, don't get me wrong, I'd love fremantle with 3.8. AFAIK I am the only one so far who has successfully booted fremantle with 3.5(including working SGX driver). But I did it just as a POC as I really don't see the benefit.

BTW you may wan't to join #maemo-alternatives on freenode, Skry and co are doing wonders there :)

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

This is pretty impressive!

I'm not hacked enough kernel to really measure how much there would be work. But reimplementing closed source parts would be good thing anyway.

*every time feature is backported it is proof that we should have newer kernel
*rumours that ARM is more supported [e.g. http://www.linaro.org/linaro-blog/20...l-upstreaming/]
*Just to keep maemo up-to-date (but maybe kernel is not top priority)

Re: [Announce] kernel-power stable v51 in Extras-Devel
 

I updated deb packages of kernel-power pre v52 from my git. When autobuilder start working again I will push this final version to extras-devel.
