[DEV] [WIP] Kexec Hardboot Patch - Kindle Fire HDX 7" & 8.9" Original Android Develop

- I have implemented a first cut of kexec hardboot patch for the Apollo and Thor Devices
- @Tasssadar created the excellent MultiROM
- I am working to provide support for our devices (Apollo and Thor) and as such this is first step
- The commit in my SlimLP kernel is here.
- This is the patch:

Should the atags used to boot the kernel be exported in an "atags"
file in procfs. Useful with kexec.
+config KEXEC_HARDBOOT
+ bool "Support hard booting to a kexec kernel"
+ depends on KEXEC
+ help
+ Allows hard booting (i.e., with a full hardware reboot) to a kernel
+ previously loaded in memory by kexec. This works around the problem of
+ soft-booted kernel hangs due to improper device shutdown and/or
+ reinitialization. Support is comprised of two components:
+
+ First, a "hardboot" flag is added to the kexec syscall to force a hard
+ reboot in relocate_new_kernel() (which requires machine-specific assembly
+ code). This also requires the kexec userspace tool to load the kexec'd
+ kernel in memory region left untouched by the bootloader (i.e., not
+ explicitly cleared and not overwritten by the boot kernel). Just prior
+ to reboot, the kexec kernel arguments are stashed in a machine-specific
+ memory page that must also be preserved. Note that this hardboot page
+ need not be reserved during regular kernel execution.
+
+ Second, the zImage decompresor of the boot (bootloader-loaded) kernel is
+ modified to check the hardboot page for fresh kexec arguments, and if
+ present, attempts to jump to the kexec'd kernel preserved in memory.
+
+ Note that hardboot support is only required in the boot kernel and any
+ kernel capable of performing a hardboot kexec. It is _not_ required by a
+ kexec'd kernel.

MultiROM Recovery Image Running
- See attached screenshot
- The recovery.img output was exceeding the recovery partition size
- I resolved this by compressing the kernel with xz reducing the output size by ~300KB...
- and have switched the recovery ramdisk to be compressed with lzma further reducing the output size by ~2MB
- That's one more step further

Strace for Android

Everybody loves strace !
So am I, thats why I compiled a static one you can use on any Android or even.. any ARM Linux system
It's unmodified, compiled with buildroot.

PS: Sorry if this was done before, i didn't found one easily.
Thanks! strace is a usefull debug tool!
bwt, i compiled strace (4.6) too

Hello, the link is now dead, do you recent version 4.6 or 4.7 statically linked?

[UTILITY] STrace 4.8 - Ultimate debugging utility now ported to Android !

about Strace
Android provides Logcat for tracing and debugging Apps , Logcat provides too short information and limited apps also programs has to support logcat or there wo'nt be any log ! this makes Android logcar be completely un-useful in large/advanced programs .
strace is a debugging utility to monitor a program system calls or signals it receives . strace is used while we want to find the reason a program crashes or finding out what causes a process not to work as expected .
strace is much more powerful than Android Logcat . unlike logcat , any process may be monitored by strace also there is no need to rewrite a program for support of strace
usage & downloading
I have ported strace to Android and it works without any bugs
download the lastest binary from this post , move it to /system/bin and set permissions to 755 .
strace has a lot of options you can find by running it using :
Code:
strace --help
most common functions are :
1- using strace to monitor a command :
Code:
strace echo hello
2- using strace to monitor an App/process :
Code:
strace -p 123
(123 is a example , use any other PID you wish )
here is an example of running strace with hello command :
Code:
ALIREZA | strace echo hello

Download Strace 4.8 from here
license
strace is a free software, you may download source of strace from here
Only 4 downloads ?!
Segfault any attemp to use it!
Running on LG P500 (ARMv6) cm-10.2
OK, guess what? Already have it on /system/xbin and that does work.
Very nice tool/utility man.....
will try it to solve issues on my roms...
thanks man :good:

Would like to try it, but the download link requires me to sign up for an account. Can't you make this available some other way?
you dont need an account to download. Between the 2 ads is the download button

You must use the a valid PID , 123 is an example .
For getting PID of an APP/Process , use the this command in terminal :
Code:
ps | grep "abc"
instead of abc , write the process name you want ! for example :
Code:
ps | grep "com.android.acore"
then search for PID in the output and use it with strace !

You need to be root to attach to already running processes.
I also find the "-f" option useful for more complex executables (which fork new processes). "-o" to write the output to a file can be useful if there is much output.

Sweet!
Huh? It's a well-known, standard unix utility, being a part of Android distribution since Android 1.6 (although, only in debug builds)...
See https://android.googlesource.com/platform/external/strace/ (note all the branches on the left)
It's good to make people aware of it, though, as it's a very useful tool for debugging some kinds of issues.

I haven't seen it, but its just in android sources and only in debug builds for debugging the android but This is a standalone build of latest STrace suitable for developers to debug their APPs . Developers will not download and compile whole android for just having a dynamicly linked strace .
Another thing , why most of you are saying its a well-known/popular linux utility ... , did I say it is not ????

But that's something that's popular to do here, a lot of people download the sources and compile the ROMs they run from source. Additionally, this is probably included in every custom ROM out there. My CM10.2 install has the utility built in.
There's no need to be defensive, the RD that's replying to you is just providing links for more reading. The better informed the users of this site are, the more cool stuff we'll see in the future.
Thanks for your strace build!

This does not work on X86 based platforms.
There're quite a few blog posts on the net about compiling strace from source.
Eg. http://discuz-android.blogspot.com/2008/01/create-google-android-strace-tool.html
I've created a precompiled tgz package that you can extract into the root of your filesystem and it'll put strace into /data/local (i.e. /data/local/bin/strace).

I prefer my utilities in /data/local.

[Q] Compiling CM 12.1 Error

Hi,
I tried to build my own rom with the tutorial for the 1+1 of cynogenmod.
The first built was fine, so I wanted to change the toolchain for compiling the new built with SABERMOD.
This is what I done so far :

Looks like an kernel compiling error, but I dont know how to fix it .
Maybe someone can help me out of this.

Click to expand...

Try another toolchain for the right CPU for you ..its solved your Problem ?
Have you setup the toolchain for the kernel correctly before you Start the compile?
