trip of kangting

We have been to kangting..yes,kangting,again~but no hiking/biking something.because we only have 7-days vacation that we choose the road trip.There's still bunch of beautiful places out there.You're get involve in a natural environment which in the wonderful creations that it must driving you to do some philosophical think.what's the purpose of your frenk'in life?what the kind of ways you need to pursuit with?freedom or dreams in metaphical, code something in physical? that's a hard issues I dont have figure it out yet.Last year,I almost die in a jungle near(35km) to kangting city.After 13 months the process of event still picturing in my mind,pretty clearly.I as a humanoid walking on the suck but wondering world that have to ask about those 3 questions again:where's my LOVE?where's my HOPE?what's the purpose of my life?7 years of itchs,but it's still hard to answer..........

the first mountain in Ya'an area we need to pass.

country side

shangli town


unfortunately,the Talmud doesnt have a full-version of Chinese translation...it doesnt means that I have to learning hebrew,right?

ya'an city


I was hiking here last year

we were passing through the tunnel

kangting



only the idiot dont drink buttered tea when you're reach the highland in the southwest of China


can you writing code within a hot spring pool on 2700m altitude?

this probabaly is highest altitude airport in the planet.4250 meters high on top of the "zheduo" mountain.


airstrip


flying here dude,it's worth to try~


airport entry

we have been stuck in mountain(3900m altitude) caused by traffic jams.damn,where's the fucking traffic police gone?Thank God,we met a group of army and they helped us to passing through,safely.

thanks,buddy.You guys effort made a smooth traffic.


traffic jams for 15km.

hello,yaks!

Xindu Bridge (新都橋)




the path to danba country

beautiful,ha?

tagong town,see?

getting near to danba





Tibetan Village in danba country

castle in danba country



we were going to cross the jiajin mountain.

hightland lake

This place is great.Im going to hiking this place next year.











go home......

exokernel,can we talk about it?

of course we have to talk about it.Actually we have been trash-talking on OS topics for few months.But we still dont get start to writing the own ones.dont be rush,man.OS is a definitely tough hack in the phenomenon world.It will takes you few years even 10 years get involve with it.sounds hard,right? whatever you think how hard it is,that doenst means we could put it away from our hacking(routines).we still need to keep eyes on it.

You may doubt that how can we keep up with new tech in a fast-food world,while People just focus on things which turning to be rushsss.I dont wanna talk about how people get fucked by this world right now.Just noticed that hardware/software co-hacking are a bunch of logies(ontology,methodology,epistemology) that across the hardcore fields in computer science(and engineering) including OS,compilers,networking.The 3logies is the strongest paradigm which existing for xxxxxx years.It's cames from the most powerful book---The Holy Bible.The 1st time of Jews and Greek's cultural collision happend about 2300 years ago that historical event formed a new way of thinking which Abraham Joshua Heschel was call it "ellipse it revolves" that means we believed something cant to prove it by reasoning but by our pure faith to LORD(religion,theology),and the rest of knowledge we can figure it out by reasoning(philosophy).The interesting is Hebrew(希伯来) and Greek(希腊) are same root in CHinese:-)

Back to the topic.Im a monkey-coder,why do I need to know above?Because you will get different informations on different postions when you hack the kernel(or should I said OS design?).A simple explanation like this:
Ontology->Trying to figure it out what OS it is.
Methodology->trying to stand on different positions look into the paradigm of the OS.
Epistemology->trying to do above 2 again and again that would making a whole organic knowledge system for you.

On the other hand,different languages connected these different world views as same as OS design.Thinking about that,The relationships between the arch of OS itself,scheduler,kernel thread execution just like,you know what,I really wanna saying"Holy Father,Holy Son,Holy Spirit".is there any possibility to reduce those components less than 3?You could try it but it will be sucked.And why does conventional OS(monolithic,even microkernel) has to make a distinction between kernel space and user space?for security issues(sin)?oohh,aha,sinful man living in user space and trying to get some resources from kernel space by scheduler(JC?).pthread is a kind of execution which existing in phenomenon world and...you might know what I want to say,right?...kernel thread is really big stuff do things which sinful man cant go through with "real desert".I cant talk more because I cant give you a clear explanation about Philosophical-Theology Model in english(a world view trouble?).

What's different between conventional OS and exokernel[1]?a lot.really a lot.IMO,exokernel is a better PTM which get closer to "the truth".You'd better take a peek[2] on MIT exo website that provided some documentations(papers)[3].exokernel's model picturing a better world than current one.A meta-kernel has been made,then hackers(not cracker) can customizing their own kernel and build their own app on it.


As a OS amateur,need to keep your mind open and trying to get "a little bit" wisdom from the beautiful creations....wowo,it's been a long bullshit,I think I need to go to bed for reading "Joel on Software"(book)[4].

May Lord's hacking spirit guide us!!!

happy gaming time II

I have a happy gaming time about 2 years ago.The AssassinCreed was a wonderful created by a talented development team,I mean UBI.Thank Lord Im still existing in this suck world and having fun with a great game---AssassinCreedII.The history was occurs in the 15th century when Renaissance getting close to the end.You can see many beautiful architectures in the game world.And even though you can see many corrupts in history of Christianity Church,but (honestly) you still can see the glorious lights from LORD by footprints of history.Im going to share something pictures from snapshots:

That's me.My name is Ezio.One of my great ancestor is altair who has gaming with you in the first edition of the game.

Venice

Florence,the first place you will see in the game world

a monastery.I came here for kick 2 guys ass and get some important infos from a monk

aha,beautiful woman."hello,mamdama"latin or french?

memory is........

Cross making me fear.....fear God,but fear no man!

..............

stealth to the castle

Venice

May Cross's lights guide us!

Santa Maria del Fiore.I wanna trip here(I mean in relative to real world)

it's a kind of Byzantine style architecture

man have a dream to fly...

And,jump dude!

one assassin show can change the world,isnt is?

world cant be changed by 2 man dies.but the 2 man themselves

btw:if you are a hacker(not cracker),I advice you spend 24 hours for gaming the AssassinCreedII.It's worth to try.

port GNU/Linux kernel 2.6.28.9 to ixp435

I have port (by a company Im working for) to ixp420 last month. That would not be fit in your kernel.A standard kernel 2.6.28.9 has been successful to port on kixrp435(ixp435 reference platform) dev-board recently. Im gonna share with you guys about it. There are few stuffs you need to get before you start the hack.

1,Download the files that you will use

2,try to get a cross-compiler(I have been using a customized GNU toolchains by timesys).My armv5b-linux-gcc version is 3.4.1-7

3,Of course you need a kernel-2.6.28.9

4(optional), you can use the rootfs I created.

I totally agree with Ken Thompson said"This is a consequence rather than a goal. I abhor a system designed for the "user", if that word is a coded pejorative meaning "stupid and unsophisticated". That's a good reason dont be expected the doc(or is called "log") might be readable as a literature. I'm writting this for hackers but not as users. Hope can helps.

happy hacking!
May Lord's hacking spirit guide us!

decompress files:
#tar jxvf linux-2.6.28.9
#unzip BSD_ixp400AccessLibrary-3_0.zip
#unzip IPL_ixp400NpeLibrary-3_0.zip
#unzip BSD_ixp400PMU-3_0.zip
#cp -r linux-2.6.28.9/arch/arm/mach-ixp4xx/include/mach linux-2.6.28.9/include
#cp linux-2.6.28.9/arch/arm/include/asm/* linux-2.6.28.9/include/asm/

do "source ixp400_xscale_sw/buildUtils/environment.linux.sh" after you have already set the right path in: ixp400_xscale_sw/buildUtils/environment.linux.sh

Copy the Makefile and Kconfig to your kernel directory that may be:linux-2.6.28.9/driver/net

#cp ixp400_eth.c IxLinuxEDDIoctl.h linux-2.6.28/driver/net
#cp config.bak linux-2.6.28.9/
#cp semaphore.c linux-2.6.28.9/kernel
#cp semaphore.h linux-2.6.28.9/include/linux

edit ixp_osal/platforms/ixp43X/os/linux/include/IxOsalOsOem.h:
replace:
#include "asm/hardware.h"
#include "asm/arch/irqs.h"

with:
#include "mach/hardware.h"
#include "mach/irqs.h"

edit ixp_osal/common/os/linux/include/core/IxOsalOsTypes.h
replace:
#include "asm/semaphore.h"

with:
#include "linux/semaphore.h"

edit ixp_osal/common/os/linux/include/core/IxOsalOs.h
replace "consistent_sync" with "dma_cache_maint"

edit ixp400_xscale_sw/src/oslinux/IxLinuxInit.c
1,add #include "linux/fs.h"
2,comment these 3 lines:
/* if (unregister_chrdev(DEV_IXNPE_MAJOR_NUMBER, "ixNpe"))
{
printk (KERN_ERR "Failed to unregister driver for

/dev/ixNpe\n");
}*/
And,add a line above it:
unregister_chrdev(DEV_IXNPE_MAJOR_NUMBER, "ixNpe")

edit

ixp400_xscale_sw/ixp_osal/common/os/linux/src/modules/ddk/IxOsalOsDdkIrq.c
replace "SA_SHIRQ" with "IRQF_SHARED"


check your kernel config
# make $IX_KBUILD_CROSSCOMPILE menuconfig

compile kernel
# make $IX_KBUILD_CROSSCOMPILE

compile npe driver
# cd ixp400_xscale_sw
# make all

then you will get 3 files(ixp400.ko,IxNpeMicrocode.dat,ixp400_eth.ko)

that's all your ixp435 platform needs.

# insmod ixp400.ko
ixp400: module license 'unspecified' taints kernel.
# cat IxNpeMicrocode.dat > /dev/ixNpe
# insmod ixp400_eth.ko

ixp400_eth: ixp1 is using NPEC and the PHY at address 1
ixp400_eth: ixp2 is using NPEA and the PHY at address 2

ixp400_eth: Use default MAC address 00:02:b3:03:03:03 for port 2

see,it works!

btw:I found a community the named openixp provided many FOSS solutions on ixp platform.unfortunately, it seems it was not update for a "while"
