[Nexus 7 Developer Discussion [Developers Only]] Tasssadar:
I've been looking through the kexec-hardboot patch these last few days, trying to actually understand it instead of just blindly porting it and after several hours of messing with assembler with no means to debug it, I've managed to remove the need for guest kernel to be patched. This is not really useful for grouper, since thanks to multirom and accepting kernel devs, nearly every third-party kernel has the proper patches. But, if I'll port multirom to some other device (hello, flo), it will be very useful :)

To know more see the changes in this commit, but you'll probably need to understand how the patch does things: https://github.com/Tasssadar/androi...mmit/2ce4130061f72430a8ddfde25346c4e528c5c30b

[MENTION=1951402]mkasick[/MENTION]: Could you please look over this? I'm afraid there's some good reason why you didn't do this in the first place, like rewriting some part of memory which shouldn't be rewritten or something like that. Thank you.
[Nexus 7 Developer Discussion [Developers Only]] Thunder07:
Perfect timing, just finished my last exam :)

Edit:

Also, this applies on top of the original patch right??

Edit2:

i can't seem to get it to kexec boot, but i didn't do much testing, maybe 2morrow night!

Edit3:

fixed, it was a problem with min-addr,

changed it to 0x82000000 and it worked :)
[Nexus 7 Developer Discussion [Developers Only]] thewisenerd:
One more question...

TEGRA_PMC_BASE is also device specific, ain't it???

So, for a Qualcomm device, what should I be using? I am guessing it is MSM_RPM_BASE, which I got from here: http://xdaforums.com/showpost.php?p=31127486&postcount=7
[Nexus 7 Developer Discussion [Developers Only]] Tasssadar:
Yes, it is SoC-specific. This is using some special register to reset the chip, I'm not sure if that is available on msm chips - probably yes, but in some different form. Your best chance is to examine restart sequence in arch/arm/mach-msm/restart.c and port it to assembler.
[Nexus 7 Developer Discussion [Developers Only]] Hal9k+1:
The address of 0xA0000000 is not necessarily the best choice going forward. It originally made perfect sense, as it is well above everything else. But now that we can boot unpatched guest kernels, we can hit the interesting situation where the guest decompression may take a full minute. At least it's when I've seen on the Ouya game console that's running the next chip after Grouper.

When I realized what's going on, I changed to 0x8E000000, as it gets me just below the 256 MB limit of cache-enabled memory that's present on a typical guest at that early decompression stage. It's enough to hold a typical 8 MB boot image kernel/ramdisk. Now the guest kernel startup is fast in all cases.

Thank you Tasssadar for continuing your work in this area, especially with finding that way to allow unpatched guests.
[Nexus 7 Developer Discussion [Developers Only]] Tasssadar:
Indeed, that's actually what I'm using in MultiROM for flo and mako (and grouper, but it is useless 'cause not all 3rd-party kernels have been updated), I just kinda "forgot" to update these threads.
[Nexus 7 Developer Discussion [Developers Only]] king960:
Would it work on devices with locked bootloaders (Xperias). I mean :does the idea of this patch would also work on bootloader unlock allowed :no devices?
[Nexus 7 Developer Discussion [Developers Only]] rachanta:
I am trying to build a kexec patched kernel integrated into a ROM. I make sure that the following code is there in the defconfig:

CONFIG_KEXEC=y

CONFIG_KEXEC_HARDBOOT=y

CONFIG_ATAGS_PROC=y

The ROM works well, except that it does not boot my secondary ROMs - kexec hardboot patch missing. I have multi ROM and TWRP recovery installed

What am I missing?
[Nexus 7 Developer Discussion [Developers Only]] Tasssadar:
Logs or it didn't happen.

Show me dmesg from normal boot into android, with MultiROM and your kernel installed.

adb shell
su
dmesg > /data/local/tmp/dmesg.txt
exit
exit
adb pull /data/local/tmp/dmesg.txt

Porting?

Tassadar which things do I need to boot kexec kernel on my device (Motorola Electrify 2) .:confused:
[Nexus 7 Developer Discussion [Developers Only]] Myself5:
[MENTION=3418703]Tasssadar[/MENTION], Sorry for picking up this kinda "old topic" but I'm sadly experiencing some problems while trying to port kexec-hardboot to the Sony Xperia Z2 (aka sirius). I applyed all needed commits (cherry-picked from a apparently working Z1 repo for stock kernel) to my CM based custom kernel (https://github.com/Myself5/android_kernel_sony_msm8974/tree/kexec-cm-12.0) and it does not boot at all. It's stuck on the Sony Logo, and it seems like I can't get any log either. I also tryed the stock cm kernel with the patch (https://github.com/Myself5/android_kernel_sony_msm8974-kexec) cause I tought it might be some incompatibility, but sadly it wasn't. Hope you have any ideas to solve my problems, cause I'm out of ideas ATM. I also checked the kexec commits for other devices (namely the One Plus One) and it seems like I got everything needed.

Thanks in Advance
[Nexus 7 Developer Discussion [Developers Only]] mythos234:
I'm sorry for picking up this older topic as well, but I always played with the thought of merging kexec support into a kernel and I'm doing one right now.. But my secondary device is a LG G2 and since the era of Lollipop began, somehow MultiBoot just stopped working and nobody can figure out why. I think they even started to build some new concept now.. So before I spark a heated debated by Note 4 users I'd love to know if you have any idea if this patch is still applicable? Altough the only way to find out is to probably just try it lol. :D
[Nexus 7 Developer Discussion [Developers Only]] regalstreak:
Bro can you please mention on your wiki that kexec isnt supported for x64 devices? It will be great help and save developers hours! I was porting for oneplus 2 when a dev told me that kexec isnt there for x64. I was shocked :P

Is any alternative available for that? Please reply! Thanks.

All other devs, who cant make multirom to work (lollipop is the x64 era) stop working. Kexec isnt supported for x64. Find an alternative for it.
[Nexus 7 Developer Discussion [Developers Only]] DeadSquirrel01:
Can Anyone help me to port this? Here is my patched kernel (ignore arch/arm64) and this is /proc/iomem.

80000000-854fffff : System RAM
80008000-80fa43ef : Kernel code
81112000-817bf797 : Kernel data
8cb00000-9fefffff : System RAM
9ff00000-9ff3ffff : persistent_ram
9ff40000-9ff7ffff : persistent_ram
9ff80000-9fffffff : persistent_ram
a0000000-ffffefff : System RAM

For kexec_hb_page_addr the value i inseted is 85500000 coz as tasssadar said 884fffff + 1 = 85500000, but I don't know what value add for

#elif defined(CONFIG_ARCH_MSM8916)
/* Restart using the PMIC chip, see mach-msm/restart.c */
ldr	r0, =MSM8916_HARDBOOT
mov	r1, #0
str	r1, [r0, #0]
loop:	b	loop

MSM8916_HARDBOOT, and if I compile the kernel it stucks on samsung logo.
[Nexus 7 Developer Discussion [Developers Only]] TechNyne66:
Someone needs to help rebuild the kexec file for /system/bin with the updated v20 that I read HAS arm64 support. I currently do not have my desktop for access to my linux os but will here by next weekend and will attempt to rebuild kexec. If someone can beat me to it, more power to us!

[Nexus 7 Developer Discussion [Developers Only]] Andrew-J-Larson:
Big question on this before I screw up anything on a Oneplus One...

If I were to have CM14.1 (nightly) as the primary ROM, how would I go about installing the kexec-hardboot patch for it. Or, if this is not possible yet, what is the latest CM version that's MultiROM compatible?

EDIT: I found that CM13 is the highest supported version at the moment :(, when CM14.1 gets the kexec-hardboot patch can someone please PM me so I can get on my phone without having to worry about multirom's "no kexec" mode (it screwed up my last rom, but luckily I know how to flash roms over again so I don't lose any of my saved data lol)

Hi, I write here because I'm a new user and I haven't wrote 10 messages yet. I have some questions for MrTapa. First of all thanks for your work. I have a problem with your rom, Optimax 3.0 on my Ray: it's happened already 2 times that the phone reboots by itself and get stuck on Sony logo. Only way to resolve is to flash stock rom with Flashtools. When it happened for the first time I was installing X-Parts from the market (I have locked bootloader), while the second time I was deleting some desktop pictures from system/etc/customization/content/com/sonyericsson/wallpaperpicker/wallpapers. If it can useful my basic configuration is: GX launcher, NXT framework, T tabbed statusbar, supercharger + zipalign (even if I tried the method for use init.d on stock kernel but with no success), SuperSU, Z theme, NXT contacts and dialer. Are there some incompatibilities with this configuration? However with the old versions of Optimax I never had problems at all.

Another question is about the battery: I noticed that with your roms the charge time is reduced compared to the stock rom, about 2 hours instead of 3 hours. Also the battery life is very short, only 1,30-2 hours with screen on (just used with system apps, with no other apps installed). Have you changed some files configuration concerning the battery?

Thanks in advance.
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] ctragas:
From my experience with st15i (Mini) and after evaluating ALL available kernels and MOST of available ROMs I can suggest:

1. About bootloop it can happen if you missed some critical step ( e.g format system ). If developer suggests to format system, DO it. You will loose your data but there is NO other option. (You can use Titanium Backup to backup your apps+data before ROM installation and restore them after). If it is a ROM bug search ROM's thread for someone with similar problem. It's statistically extremely rare to be the first to face the particular problem. Maybe your problem is all ready fixed (after other member's question to developer).

2. Battery drain: the most important factor is kernel. Usuall, ROM plays minor part in battery drain. With the right kernel and adjustments (governor - I/O scheduler) you can even double your battery's life. In my device it was 20-24 h to 48-60 h after flashing a custom kernel. You can also use a battery saver app (like Ultimate Juice, Battery Saver DU etc).;)
[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] XDynamite:
Thanks for reply. About first point I actually done every steps that the developer has suggested: wipe user data, format system, data, cache, dalvik cache, battery stats.

About the battery I don't know why, but the difference between original rom and Optimax rom is clear. I have reflashed the modified rom just few hours ago, the battery drain has been about 20% in two hours with phone simply in standby. I don't think this is a normal behavior. With original firmware it doesn't happen. The condition battery is good. I have stock kernel because I have locked bootloader.

Maybe this problem is about root: or the root process has not gone totally succesful, or the cause of the problem is SuperSU, wich I have never used before but in my opinion it is not very stable. It's better Superuser.

I wanted write on Optimax thread but I can't because I'm a new user, I would be grateful if someone can contatc the developer (MrTapa) about my problem.

Hi, my device is also showing these strange vertical bars, one of them is exact in the middle of the screen. It looks like banding and is mostly visible on grey or darker backgrounds (for example during the loading screen on play store). Today I compared it with a nexus 4 from my local store, which showed the exact same vertical lines. Increasing the brightness makes it even more visible. Is this a common issue due to the design of the display? I've never seen anything like this before on ips panels, my 4xhd was perfectly fine.

Should I RMA?

im using one of the color configurations posted on xda that makes it a little better i barely notice it now or maybe im just used to it already
[Nexus 4 Q&A, Help & Troubleshooting] 666fff:
I read somewhere that these faint lines are due to the gamma values being set incorrectly on displays. So LG have screwed it up in the factory.

All displays don't have this as some people are saying. My old HTC Hero didn't have it, my ipad 3 doesn't have it, iPhone 4, iPhone 5, iPhone 4S, SGS2. All perfect displays. I don't think there's much you can do apart from messing about with colour control but you have to root to do that and it probably won't really make a difference.

My problem is three or four faint wide lines visible on grey or white backgrounds, gonna call Google and ask them what it is.
[HTC One S] Roundtableprez:
OK don't flame me for being a noon about this but would it be possible to port gingerbread to the one s? Maybe like cm7.1? I know this sounds really dumb and alot of people are probably going to be like "why would you want gingerbread?

Possible? Of course it is, its open source.

Will anyone in their right mind do it? Very much doubt it.

A friend and I are working on a thought project and I realized it could be made into a reality with the use of some cell phone hardware.

Here's what our idea is:

Goal:

Build an autonomous RC quad rotor helicopter

Use phone camera for live camera Feed,

Use the phone's accelerometer for flight control,

Use phone GPS for navigation

Use wifi for piloted control and camera feed transmission

I realize we would need to use a high end phone's hardware with a good processor.. And that a TON of code would need to written.. But is this even possible??

Thanks for any help.. My friend has experience building RC planes and cars and quads.. But integrating a cellphone for autonomous flight was my idea, and I dunno much about how it could potentially work.
