@Jarmster

The performance is exactly identical, it's binary: either you run in
GameOS mode (with GameOS permissions), or OtherOS mode.

graf_chokolo is an lv1 master and his Linux booting method is very
useful in many circumstances, there's no doubt about that. I deeply
appreciate his work.

I'm just saying that he's getting overly excited about Linux-as-GameOS
because he's just discovered it himself (since unfortunately he didn't
follow existing work). His method of getting Linux to run with GameOS
permissions is novel, useful, and great, but the end result once you
actually run Linux is identical to what I was doing several months
back. He crafted a new alternative path, but several people have been
taking trips to the destination for a while now ;)

marcan表示他很敬佩graf_chokolo在完全沒有參考他們在C3研討會以及之前所提
出的方案的情況下，走出自己的路，而且這條路不比他們的差。只是殊途同歸，
兩邊最終的結果是一樣：讓Linux 取得GameOS的權限。

marcan把 Linux用檔案的形式安裝在GameOS裡面，透過USB 漏洞啟動 Linux，因
為HV本身就會授予GameOS相對應的權限，經由GameOS啟動的 Linux自然繼承所有
的權限；graf_chokolo則是直接控制HV載入 Linux，並命令HV授予GameOS的權限
，所以兩邊的終點是一樣的。簡單講就是marcan那邊是用騙的，騙到GameOS權限
，graf_chokolo卻是直接用搶的，直接綁架HV搶到GameOS權限，更乾淨俐落。

OTOH, I do believe he can contribute greatly to lv1 integration. For
example, since I know very little about lv1 internals, my plan was to
eventually be able to install Linux to the GameOS partition, as a
loopfile, so you can install Linux without reformatting anything.
However, since I bet he can figure out how to create new HDD storage
regions, that's a great alternative that's closer to what the old
OtherOS did. I'm not even remotely dismissing his work and I think
he has a lot to contribute towards deeper lv1 understanding and how
to make use of its features effectively, as well as booting Linux
straight from the HV.

marcan的方式是把 Linux以應用程式的方式裝在GameOS裡面，要用的時候再啟動
，所以不需要將磁碟重新格式化；graf_chokolo則是重新分配磁碟的分割區，把
Linux以作業系統的方式裝在新的磁區，所以視情況也許需要重新格式化整顆磁
碟。

So pick your poison: the old USB exploit, kmeaw's AsbestOS
installer, or graf_chokolo's lv1 patch. They all get you the same
Linux with the same permissions and performance, it's just a matter
of which booting method you prefer ;)

所以說，想要灌 Linux有兩種選擇：1.kmeaw 的AsbestOS方案或是；2.graf_cho-
kolo的 Lv1破解方案。要比安全性的話第一個當然是很安全，沒有動到太多太底
部的東西，所以變磚的風險很低，但只要$QNY一修補漏洞，就得另覓出路；graf_
chokolo 的方案有阻止$QNY修補漏洞的潛力，但安裝的知識及變磚風險較高。

@moscode

It's probably a mismatch between the kernel and the rootfs that you
used. Since this is all pretty new still, unless you're comfortable
compiling your own kernel, I suggest you wait until I get a chance to
add HDD boot support to asbestos, after which I'll build a nice
Ubuntu image with a patched kernel that should be easy to install.

This is one place where graf's method does have an advantage: since
I assume he knows how to convince the HV to boot with 128MB bootmem,
he can actually run old OtherOS kernels unmodified, including
petitboot. I need some minor kernel patches and some AsbestOS
integration, so you'll need new kernels. My method is also
compatible with 128MB bootmem though, so eventually we'll probably
both end up using the same kernels anyway.

Finally mounted all HDD regions of GameOS on my PS3 Linux :-)

Here is my answer to SONY's threats.

UFS2 mounted on Linux – http://pastie.org/1535218

FAT32 mounted on Linux – http://pastie.org/1535222

Working now on VFLASH and FLASH drivers for Linux :-)

And thanks to Mecenefeaa and his Dad for the help with Linux :-)

@Mark Webber

I will write a driver on Linux for user-space programs to access the
ENCDEC peripheral device soon :-)

這種東西做出來整個$QNY在 PS3主機上的加解密機制要全部垮台了。

Oh no, not SONY agents here again :-)
討厭啦，$QNY又來嚇唬人家了啦！

@SONY

I will not stop my HV hacking and reversing, i cannot, it's like the
air i need to breath, without it i'm dead. I'm not able to stop,
and your threats make me even more motivated :-)
我絕對不會跟你們妥協，因為我得了一種不破解HV就會死的病，$QNY越是嚇唬我
就越有破解的動力。怎樣，$QNY踹共啊！
