So i have finally done it. After long hours of solving problems and such, i have gotten kexec to compile on the ARMv7 arch.
In computing, kexec (kernel execution) is a mechanism of the Linux kernel that allows "live" booting of a new kernel "over" the currently running kernel. kexec skips the bootloader stage (hardware initialization phase by the firmware or BIOS) and directly loads the new kernel into memory, where it starts executing immediately. This avoids the long times associated with a full reboot[1], and can help systems to meet high-availability requirements by minimizing downtime.

Holy crap; you're amazing lolgud. I'm glad i got to watch this happen.
Not kexec
I hate to spoil the party but....
This isn't kexec.
You have compiled kexec-tools, the user space programs used to control kexec.
kexec is a feature of the kernel which allows it to be hot swapped with another kernel. Our kernel doesn't have that feature, it was disabled. Since our kernel doesn't have that feature these tools do absolutely nothing.
I can cross-compile most anything I download off the interwebs. That doesn't mean it's gonna work on my Nook.
We are gonna need to load the kexec functionality via a kernel module, or simulate that functionality with a kernel module.

Here's an idea, maybe something else can contribute or confirm it might works..
the Nook honeycomb image is actually running on top of a 2.6.29-omap kernel, which indicate that only some parts might require 2.6.36.3 functions.
I know that the main problem for me porting it, was the libc.so which uses kernel calls not found in our existing 2.6.32.9 kernel. so it crashed due to some cache functions not implemented.
- could the missing cache functions be implemented into our 2.6.32 kernel?
- can the Nook edition with a working libc.so (hopefully without FPU function compiled) be used to replace our xoom image libc.so which crashes?
So to make an early edition can we merge the ARMv5 libs (i assume it is from the emu) and use this with xoom edition and then keep our libnv* environment which is compatible without our nvrm_daemon (which no one can fix, although a proper kernel work for booting 2.6.36.3)
ideas.. but if its possible to put into "real life" is another story.
and how many can do experiments?
Artem wrote he is on the 2.6.36.3 kernel, but since we might have an option to go around, maybe also worth considering, if display driver lacks nvrm_daemon support.

i tries all this out now.. and got passed some link references between libs but the "libc.so" issue came coming back..
so it did not work..
im closing the idea here :-( not worth spending time on, so only the solution with updating kernel and rewriting drivers must be the way forward.
May be I should wait for ubuntu 11.04 or some other linux OS for folio 100

correct,
we already know it has different resolution . and probably better display now, and no hardware buttons on the side, so no I2C used for this..
i think its very different, as it probably also got 802.11n wifi now, which we dont have and need different ar6000 driver.
i think its a long road downhill for folio100 if the 200 edition should be anything close as source for porting.

Please, I'm no expert in this, so bare with me for asking questions.
Honeycomb uses a different kernel than Froyo ok.
For Froyo we have the source for all (hardware) drivers ?
Can the "android" part of Honeycomb (from for example Xoom) be put on
a kernel with required hardware drivers or are there stuff in the "android"
stuff that is hardware dependant ?
Is it hard to port drivers between kernel versions ?
Just trying to understand the many tasks need to get Honeycomb on Folio.

The problem in this case is there is no honeycomb kernel sources out there.

xoom kernel source is available, koush used it to make his clockworkmod work , and it works fine, and its also used for oc'ing.
but its pretty much the tegra2 source we can get from nvidia. but alot of porting to do.

Why we need more than one ROM?

But if many Developers work on one project together, this project will be good

i think sauron should work on a cm7 port and base his future work on cm7
what wider range then with cm you could have you would profit from much more developers (userspace and some kernel work for sure too) and we would be faster on updates from google and completly independent(well not 100%) from soon stopping asus support
if we want to gain some life for our gen8 this is imo the last chance we have.

@Lennb:
Why are there so many cars when a xyz is doing ok?
Because everyone has other needs, other opinions and other wishes.
So if you want to stay with Uruk, fine.
If someone wants MIUI.11 or CM19 ported it is his wish.
And if he is willing to pay for his wishes, than let him.
@gbohm:
€10 from me
my worry with urukdroid is that it is still based on archos because userspace stuff isn't open sourced, so the experience stays.
with cm you can work on every part of the "rom" the possibilities are a lot bigger.
you can't compare a modded rom with a custom kernel to a full blown aosp implementation.
i think sauron makes a wonderfull job but he is working on a platform with a short life span, cm is here to stay and with any new dev it will get better.

Wrong.
As stated often before we have the sde, which allows us to install another kernel.
If someone would implement one with nandroid features, scriptingsupport and second boot we have the recovery.
There is no need to break anything.
And juts o get CM working that is not even needed.

Yes it got cracked. BUT no developer in his right mind is going to use that crack.
If you apply the crack the possibility of bricking your device is growing exponentially because there is no fallback position available.
Other android devices have fastboot or sd card boot out of the box.
Archos has neither so if you patch the boot0 and avboot and the next time the user wants to install a stock firmware there is a big possibility the device will be bricked if that firmware updates only one of the two boot loaders.

You can't tell people what they want.
You can only listen to them. They're willing to PAY money to get a CM7 port. That means that they're pretty set on one.
I would like a port too and I'm willing to put up $20 for someone to port over clockworkmod and another $20 for a stable CM7 build.
CM7 would be WAYYYYY faster than Uruk or any other manufacturer firmware. Have you SEEN how slow the Archos Gen 8 tablets can be? Something OBVIOUSLY doesn't work the way it's supposed to. Nothing with a 1GHZ snapdragon processor that runs Android 2.2 should fall so behind in nearly every task it takes on.
Not to mention that 256 mb of ram should be more than enough.
20$ from my side too, for stable CM7+ on archos 101
thank you i hope that we will raise some money to attract a dev who could buy himself an archos and get it paid from us after he build cm

Wait, does that make me bi-curious??
Opening a thread for Webtop Mod, I wanna know what do you expect from it prior giving it to you, so I can set it as you all want.
is possible to have a dump of original webtop!?
some one have try the hack for Atrix/photon?
If you want a dump of the original webtop, download the Fastboot ROM in the ROMs thread.
The WebTopMODs for ATRIX/Photon shouldn't work as expected as they're meant to be used with Tegra2 (VFP), not with OMAP4. They're different.
Mine is meant to be used on OMAP4, its binaries are compiled with full OMAP4 support.
Chromium on Razr Webtop?
I've gone through your Netty enhancement (very impressive results, I might add!) and am thrilled with the results so far... BUT, upon installing Chromium using the apt-get functionality, I'm running into errors - something along the line of the application not properly reporting the timestamp back to the system. End result is that the application runs perfect for about a minute or two - then the system kills the app.
Have you had any success in getting Chromium running? That's by far my #1 want at the moment.
(And note - I'd post this in your development thread for the mod, but the system won't let me do so until I reach 10 posts... I think that's a feature.)

Well everyone my phone is giving up the ghost. There are some unknown hardware failures that are causing massive power draw. Making the phone run hot with minimal processor use and the battery life has plummeted to going from full charge to empty in an hour or so. Charging is almost impossible because of this.

I figured that with cheese, but hell "sun shines on dogs ass once n a while". lol
The manuals are an interesting read, sometimes boring or stressful. Have held onto mine for awhile and its still in like new condition. Just think it could be a killer phone! Read a new article mentioning a NEW law passed allowing cell unlocking and the tools behind it. (Reversal of Library of Congress)
But I wish you good luck!
just a odd idea I thought I would share
I wonder if its possible to patch a kernel on load using safestrap
I am wondering if maby we can hex-patch the DVFS table at execute to at least gain some overclocking
I read the kexec thread but the consensus there is that development is stalled waiting for a breakthrough
thoughts :fingers-crossed:

You can overclock via module sure, hex patch prob not needed.

hrmmm.... you talking about patching the dvfs kernel module or writing a custom module ...
if so I am surprised nobody has done that yet ..
is hex-patching from safestrap at all feasible ... it would grant you the 'keys' to all manner of "doors"
I used to fiddle with it on my cheap mk808 tv stick before we had kernel sources
I am surprised nobody has used kmodule's as a "attack vector" people seem to be chipping away and the Mountain that is kexec instead of just focusing on patching the issues we have with the stock kernel .. . a few years ago somebody was doing hex patches to implement kernel changes on the first generation of rockchip powered "tv sticks" the same logic should apply here
then again maby I have just been out of the game for way to long ....
*continues pondering*

I have dabbled with this, using a custom module based on the 8660 overclock module I found source for somewhere. The reason kexec is so much more desired then fixing the current kernel is because patching the current kernel might give us more io schedulers, overclock, custom governors etc, but at the end of the day all that crap isn't worth much on the poor excuse for android ui known as touchwiz.
Idk about you but I can tell you I for sure would not want to post a thread on overclocking or modifying cpu via modules in this day and age of 'the entitled xda user'. Maybe that's why you don't see any threads.
You bring up a good point about how people don't understand the various uses kernel modules can provide including but not limited to being attack vectors (though to some degree this is being done with kexec).

ill be the first one to admit I haven't keept up on this stuff simply because the effort started outweighing the gain
it just seems to me that people are chasing clouds ... with kexec the possibility of getting it working is basically nill due to lack of debugging information so why not attack something you can debug such as a kernel module hell in theory it should be possible to add io schedulers and governors via a module hell with a properly 'crafted' module we may even get kexec(kgraft?) as a result if you could create a exploit you could use to the proper effect ..
I agree that touchwizz is utter poo and should be stabbed with white hot knives and buried under 12ft of cement but the phrase "if life gives you lemons ... make lemonade" rings to mind ...
I am sure somebody will give me the usual speech about "if you are so smart do it your self" but sometimes people just need to step back and look at it another way .. + I am fighting insomnia and am on my third shot of jack ...
wow did I really write all that jesus ... no more jack for me at 12 am...

Lol. At least your question is a good topic of debate. Most questions and posts in our forum are boring to me but this isn't, so there's that I guess.

realistically you probably could't alter to much but adding overclocking a variety of minor tweaks could be done in hex
on a personal note I would be content with figuring out how to get some overclocking/undervolting done
