Hacking (vWii) - Tri-Core Linux

just checked

Hello,
I tried with a 2Gb sdhc (the one I usually use...) but not enough space !
Works with a sandisk 8Gb
I successfully launched "trinux" but my keyboard is not supported (Microsoft wireless 1000)
Try to change USB port but still doesn't work, but keyboard recognised when plugged.
Can't go further, I have no other keyboard

I am so outta the loop Much has happened.

something (somewhat unrelated) that catches my eye there, the pvr = 0x00087200 ...
I've noticed that the code on the fail0verflow blog checks for a pvr that ENDS in 0101 and the 1-512 title checks for a pvr that STARTS with 7001, neither of which happen to match what's shown here.

I would have assumed that all Wii U's should have the same pvr value but just out of curiosity, I was wondering if I could get the results of a few more people running that "cat /proc/cpuinfo" command to check it out (this would include both on a Wii U AND a normal Wii to compare) ?

I ran "cat /proc/cpuinfo" using my 3.1 (WIP) kernel on my Wii console and got the same output with the exception of model but that's expected as the MIKEp5 patch isn't consistent with the mainline naming (nintendo,wii). Also, I ran lscpu and got the following:

Architecture: ppc
Byte Order: Big Endian
CPU(s): 1
On-line CPU(s) list: 0
Model: nintendo,wii
BogoMIPS: 121.50
L1d cache: 32k
L1i cache: 32k

Until the locations of the other CPUs on WiiU consoles are determined, I would expect the same output as above from them too (except Model). I revisited the commits between 2.6.32 and 3.0 as well as the MIKEp5 patch and didn't find anything that prevents SMP on PPC. From what I can tell, we'll eventually need to alter the wii.dts and starlet-mipc.c at minimal to add the missing hardware registers for the remaining CPUs and a function for initializing them. I don't understand how the extra CPUs being disable in vWii differs from how the wireless card in the Wii was disable in GameCube mode. From what I understand, 3 cores should be just as impossible as I don't think that they are controlled directly by the same hardware. As for the CPU frequencies, would I be correct in saying that we're stuck with the current Wii CPU frequency in vWii and that overclocking it to the WiiU frequency isn't going to be possible as the frequencies are fixed?

Maybe works the same as between Wii et GC mode in wiis ?
Crediar and tuedj managed to switch to "gc mode" without rebooting the Wii.
The also managed to run GC games, maybe by using another mode of Wii U proc ?
But, I wonder if eMMC would be accessible via linux ? Drivers exist in BSD, but it must be for "regular use" not for raw dump...
I also saw that there was a mistake in the driver one year ago.

Don't know if it can be use in any way....

I need someone to test a new kernel for me. Based off of DeltaResero's 3.0.86 build. This includes some minor patches to the kernel source in hopes of supporting the WiFi chipset(s) on the vWii.

http://vwii.idfbest.com/upload/zImage-3.0.86-CARVER .elf

backup your bootmii/ppcboot.elf, rename this file to ppcboot.elf and place in the bootmii/ folder of your sd card.

Please report back. Thanks

do you have the ability to mount linux filesystem?

 

[Deletedmember331810]

[Ninja_Carver]

On the virtual wii or in general?

in general- i'm going to have to find a way for users to update their filesystems without an internet connection in the meantime. It's much easier if you can somehow mount the linux partition either inside a linux LIVE CD (on your desktop) or natively in windows with some special drivers.

However, please give this kernel a test, its 3.0.86 based off of Delta's git repo. I tested this last night and appeared to work well. Please confirm.

Doing this now. Give me a few...

EDIT:
Doesn't recognize my keyboard anymore. Using the same one since your very first test.

Gets to the trinux login but will not load my keyboard.

i have nothing else inserted except for a 2gb sd card.

EDIT:
It used to recognize ANY device upon plugging into the USB receptacle, now, nothing.

Tried and failed 4 different times now... Will not load any of my USB devices now while in your application.

This is likely likely due to the USB driver being unfinished and lacking proper DMA support. Someone recently sent me a link to a repository with the fix for 2.6.35, so hopefully sometime this Fall I should have some time to forward port it too and add it back in if no else does. For now, only keyboards and mice work with certain configurations. For now, I find the cheaper keyboards/mice generally have a better success rate.

Testing now, Ninja and yes, with a little help, I can test anything you want me to test, whether it be in vWii or a pc.

I have been using the same GM321AA corded HP keyboard for every test he has asked to be performed.

I will let you know.

EDIT:

Don't know what to say... None of my keyboards or any USB device for that matter is even recognized anymore with the last two kernels that you have asked me to test.

I went back and tested a previous version and it seems to to recognize all of my stuff. If only you could re-implement whatever is now broken... If something, in fact, is broken...

Hmm... unplug and replug the keyboard in a few times, testing it after each plug/unplug... let me know if that does anything for you. Your "working" kernel version was 2.6.32. This kernel is 3.0.86. A big jump. This is a monumental leap in our development as in all likelihood we will need an updated kernel/userspace in order to build a sustainable platform from which homebrew can be based off of. Developing on a 3 year old system is meh.

no, if you could, do the following:

mount /dev/mmcblk0p1 /mnt
zcat /proc/config.gz > /mnt/kernel.config

shut down the system with "halt" command, and place the sd card in your pc and upload that kernel.config file for me.
also, the output of the 'lsusb' command would be helpful in diagnosing your issue.

thanks

Tried every character on the keyboard with shift and without shift and cannot get the ">" symbol to come up. Any certain key combination? I notice that the only keys that work correctly in this application are the number and letter keys. For example, I have to press shift + 7 to get the "/" symbol. Clicking on the actual symbol on the keyboard gets me a colon sign or a period, depending on if I am pressing the shift button. Sorry for even asking. I have no idea why it is doing this... Has since day one of testing...

I CAN get it to mount though, if that means anything...

basically the linux distribution you are using right now is the whiite release, which is ancient, and uses the spanish keyboard mapping. if you type:

swapon /dev/mmcblk0p3
dpkg-reconfigure console-data and select ONLY en_US and en_US.UTF8, your keyboard mappings should change to english.

I chose pc / qwerty / US american / Standard / Standard and everything works fine now. Thanks for clearing that up for me!

HERE is the file that you requested.

uhh this website is terrible, it won't let me download the file, http://vwii.idfbest.com -- upload it here please, thanks
