[Q] Question ; Flashing and overclocking Xperia Play - General Questions and Answers

Firstly, I'll apologise if this is in the wrong section.
Secondly, I apologise you've had this question asked dozens of times and I know there's threads right above where I'm typing.
Onto my question.
I'm fairly new to things with mobile phones as I've been stuck on the Symbian SE Satio for the last two years.
I've just rooted my SE Xperia Play (UK Region, so R800i iirc?) and I'd like to flash to the kernel/rom (Don't crucify me) that works correctly ; In that I'm able to use my camera and Wifi (Or at least, have the ability to with further flashing) and allow me to overclock my Snapdragon.
The reason I'm wanting to overclock the phone, is such games like GTA 3 have a stuttering issue, I'd wager it's down to the lowish specs of the phone and hope clocking the CPU could remove that stuttering, as from reading around it seems the snapdragon has quite some headroom (I've seen 2GHZ being branded around, though I'm more than happy with 1.6GHZ, though 2GHZ wouldn't go amiss )
Since I'm new to phones, when I overclock the CPU, would that then overclock the GPU with it? Or is their a way to overclock the GPU? (I've also seen that branded around before)
Now, onto the overclocking, I see kernels/roms such as doomlords, but reading through instructions I'm getting absolutely bamboozled and losing track.
I've done DOS flashing before with GPU's, if it's anything like that at all? (Again, don't crucify me yet!)
Cheers.

[PROJ] Overclocking the Adreno GPU on Snapdragon Devices

I already posted this in the Nexus dev forum, and I hate to clutter the boards, but I know that there are a bunch of talented devs here that may not see it on those forums. If we can bust the 30fps cap for good, and get the GPU overclocked, then we could see some serious gaming performance out of our Snapdragon devices.
I'm sure we all heard about being able to overclock the GPU on some of the old MSM devices, but the Snapdragon handles the graphics chip in a different way. The goal of this thread is to try and overclock the GPU on Snapdragon devices as well.
There is nothing GPU related in acpuclock-scorpion.c (the Snapdragon cpu clock settings) at least for setting gpu clock speed as far as I can tell.
In board-mahimahi.c (Nexus board file) and board-supersonic.c (Evo board file) there is some kgsl init code, but so far as I can tell it isn't setting the clock there, instead it seems to be pointing to PWR_RAIL_GRP_CLK to set the clock in both devices. It defines the variable in each of those files but I'm not sure where that variable is set, since it doesn't seem to be in any of the other board files as far as I can tell. I could be completely off here too though.
In drivers/video/msm/gpu/kgsl/kgsl.c there is a method called kgsl_clk_enable that seems to be called whenever the GPU is enabled. It looks like this:
Code:
/* the hw and clk enable/disable funcs must be either called from softirq or
* with mutex held */
static void kgsl_clk_enable(void)
{
//clk_set_rate(kgsl_driver.ebi1_clk, 128000000);
clk_set_rate(kgsl_driver.ebi1_clk, 245000000); // Looks like it sets the GPU clock, right? Wrong.
clk_enable(kgsl_driver.imem_clk); // Enable the clock
clk_enable(kgsl_driver.grp_clk); // Enable another clock, but why?
}
The line that's been commented out is the original value, I replaced it with my value on the line below it in a failed attempt to overclock it. Probably a stupid effort on my part, I doubt it's that simple, but it was worth a shot. The comments at the end of the line are also my additions.
According to the clk.h files in the standard linux kernel, clk_set_rate is obviously a method to set the clock rate. The first variable is a struct that tells it which clock to set, and the second variable is a long value that is the rate you want it set at. Is it setting the right clock there for Snapdragon chips? Or is it only the clock for older chips?
I'm in way over my head with this source, I'm but a lowly Java dev, but I really wanna solve this. Can anyone with a little more experience than me throw in a little more info? Sorry if it doesn't make much sense, if it isn't clear just ask me & I'll try to explain a little more.
Regards,
Jesse C.
EDIT: Okay I did a little more digging and those kgsl settings should work for QSD8x50 chips. In the config file, under Drivers, Graphics Support, it allows you to enable 3D accelleration for QSD8x50 & MSM7x27 chips. The tag for that is CONFIG_MSM_KGSL_MMU. If you check in kgsl.c it checks to see if that is enabled in the config, and if it is then it compiles and uses kgsl.c & all of the kgsl code. That tells me that the clock is either not being set, or the wrong clock is being set. I'm adding some debug code right now so I can see in dmesg what code is actually being run.
Dude I have no idea how to do this but bump and best of luck

Yeah I saw that, but that won't work for us, because it is for one of the old MSM7500 chips instead of the new QSD chips we have in Snapdragon devices.
I am working on a few things now and I recommend you check the Nexus forum since that thread is a lot more active.

okey, But as far as I know that code is not standard... Becouse the Vugue msm7500 device is originally WM device.. so the Smart dzo managed this custom code.
I wil follow the nexus form .. This is Damn interesting !
i wish you guys the best of luck..wish i could help..i love xda..lol
I'm going to bump this, would be nice if more people were working on this.
Man... I absolutely love my phone. It really sux that this even needs to be asked. This device is so much more capable and I cannot understand why HTC would cripple it so badly. Look at the Samsung galaxy s or the Droid x. Or even a more similar phone like the nexus or incredible. They all stomp this phone when it comes to anything graphics wise even if it is just swiping home screens. It makes me sad. Lol
I love how it makes you sad, but you still lol. Lol (correctly placed)
This is big but first let's get a true cap fix!

How is there such little interest in this subject? This intergrated gpu will probably overclock like a beast... and maybe we can get actual fps.

I'm thinking this is also one of those things awaiting source. Even the overclocked kernals make my phone reset so I'm waiting for a more stable release myself. Since you're still posting here does that mean you decided to keep your evo?

I don't know, yet I am in deep havoc lol. I activated my phone on the 20th. I have till 13th of July to pay my bill, so don't know.
I mean the locked bootloader of the Droid X is kind of lame. Also on the Evo, I have a 10$ discount because of the IO conference... unlimited texts too, and I bought two batteries for it with a charger(for 10$ lol, and they actually last a long time 1500ma, I put the 2 extras in my wallet)
Also I think I can upgrade my phone right away already if I read things right, so if Sprint gets an awesome phone I can upgrade to that whenever.
Verizon is more expensive, but I like how they let me do a 1 year contract. The Droid X is also nicer, I mean it has a better camera, and the mic quality when taking videos isn't piss, hopefully someone fixes that. It also has a real graphics card.
So yeah, it's hard to decide. A better phone, vs saving me some money. Though I plan to attend the IO conference once again. I'm still porting my distrubuted prime client onto Android, hopefully it will be high performance. So it's not like I just go there for a phone ^^. Hell I didn't even know about the phones till they said "Where do you want the Droid delivered" I lol'd. Though my time is limited, summer classes at UC Berkeley are tough : /

Yep, looks like til we get the kernel in our hands they're tied.
Also what's the point of overclocking if their is still a limit on FPS..
Eventually this will be the next thing on our todo list

There isn't really a fps cap with the novatek kernel hack. It made the display much smoother for me and I am using it on EvolutionX. So beast.
Good news about the drivers, maybe we can actually see some overclocking now.
I want this to happen!
Nova runs pretty well on the Evo. Gameloft updated it recently.
I would just like for iphone ports to run well.
I hear the Palm Pixi has the same GPU. It is clocked at 190mhz. What about the Evo?

The Pixi doesn't have the same GPU, it has one of the low/mid-range MSM7227 (I think thats the model?) chips. It's similar as it's one of Qualcomms latest gen chips, but it is NOT a Snapdragon so it's different.
Also, the Snapdragon GPU's on HTC devices are clocked as follows:
GRP_CLK: The actual graphics clock, 256mhz
IMEM_CLK: The gpu memory clock, 256mhz
EBI1_CLK: As best I can tell, the bus that the GPU is on is EBI1, this is the clock for it, 128mhz
If you want more info, look here: http://forum.xda-developers.com/showthread.php?t=710850 since that thread is a lot more active, but please don't clutter it, there's actual devving going on there
Thanks for the info. I just wonder how they're going to get 3d games to work on the Pixi then... weird.
It was announced that the Pixi would get 3d gaming with the 1.4.5 update.
Much better (Y)

[Q] What makes Android so slow?

Im on Android since more a year now, starting with T-Mobile Pulse and since summer, going on with my HTC Desire.
My question is, why android needs this power of hardware, in order to run smooth. The old iPhone 2G got nearly same hardware to the pulse (550 MHz, 256 MB RAM etc), but was much faster(smoother). Ive read a lot about hardware optimised code fpr ARM7 or similar, but the performance is still poor, even with overclock on leedroid 2.2...
On my second computer with a intel pentium III Chopperine 933 MHz i could realy good surf the internet, even nowadays, or play games like battlefield 1942 or counterstrike.
Could it be possible, to improve the perfomance by hand otimising the code? Would even spend time on this, able to prog, but at first i want to her your oppinions.
Greets from Germany and sorry for my poor english
The fluid ui that the iPhone has is mostly because they use gpu accelerated support. Android for some reason does not and I think only minor ui features are done on the gpu, some phones might have custom work done and its why it feels more fluid or less slow.
The other thing is a iPhone is standard in hardware. You don't have the issue of a iPhone 4 with or without more memory or less. It's easier to code and optimize when you have only a set of rules.
What are you doing to your phones??
I have a Nexus One (same hardware as the Desire) and i'd willingly challenge any iphone 4 user to a speed contest
GPU accelerated GUIs make sense to me, but die missing feature in Android doesnt really make sense. As we know, there is an AMD Z340 GPU inside, could it be possible to make it boost the graphics in 2D mode?
What iam doing with my desire? whoa, even surfing this page without the xda app isnt really fun, just slowy moving flash sucks performacne in huge numbers, that websites arent rally usable at all when running a video.
Now on Desire, most thinks are running fluently, but there are still lags, even with the custom rom. Using the Pulse was horrible, while it got 550MHz CPU and 192 MB ram. remember, its a mobile!
Here is a german report about software tweaking, which could make software 5 times, if the developers would reconcentrade on the used hardware again, like they have to do on gaming systems like GBA or newer. GBA got abot 3MHz! but runs Pokemon very well. Now imagine what could be possible, if our operating system would be better written.
Question again: it is possible to do some tweaks on a kernel or eveb androiditself without being msater coder?

XT720 Motoroli performance issue

In my opinion, the XT720 is a piece of junk. I'll take the Galaxy S over the XT720 any day. As far as "hacking" goes, you can only root it, overclock it, install app2sd, and install JIT. There are no custom ROMs because of the locked bootloader. The phone isn't smooth at all even when overclocked at 1000 MHz (Unless you have like two homescreens and 1 widget). The only good thing about this phone is that it has a 8MP camera with Xenon flash. Take note on spiderx_mm's post, he has everything covered.
If you'd like, I'll sell you my XT720 if you're in the Toronto or Ottawa area. It's lightly used and has no scuffs or knicks.

u proof me wrong dude!..here my 7 home screen...
The XT720 is quite laggy even at 1000MHz. I absolutely despise this phone.
Hi heat my XT720 all ppl have 2.2 yeah all and my XT720 don't even Moto think to get it out i have post to Moto on facebook and i say to do them i heat Moto and even my friends thy never will buy Moto what ever the do if thy give it for me for free i will not take it i have order Nexus S so bye Moto for ever ...........
This phone is a piece of ****. Im using a motoroi(korean version of Milestone) this phone is slow as hell on 2.1. After waiting for how many months this is what i got? All i got is a hotspot tha i dont use. I expect sonething new or speed boost. Speed boost especially. But its getting worst. F.... This phone. I tried all the tweaks. I even overclocked it to 1.2 ghz. But the phone just reboot randomly. Now im using it just for sms and call. Even during a call its so annoying that the screen was so sensitive the i always touched the mute button accidentally..
That's weird. You say you have Motoroi, but the Motoroi has 2.2 atm. Please explain
I totally love this phone. It's the best phone I had to date (I swear). Especially the camera rocks and unlike others, it works extremely good here and no pixels at all like some suggest
I don't care for 2.1 to be honest. 2.2 is a free update so if they don't wanna give it, then fine, I don't care. I don't need 2.2 anyway. If there would be a reason to have 2.2, then I say it's for the apps 2 SD, 'cause my internal memory is almost full So I leave it to Dexter to make an awesome 2.2 ROM and count me in as a tester for the rom (-hint- MotoBlur is awesome -hint- )
I mean the phone is slow on 2.1. I thought that they fix it on 2.2. Yah its weird that`s what i thought when i got tjis phone. But my korean friend has a galaxy s. And i played with it. Man! My motoroi was way far than this. Anyway maybe im wrong. Maybe the milestone model was more faster than motoroi.

I'm not sure what the issue is. I have my XT720 (NA version) overclocked to 1000mhz on 58 vsel and find it to be quite stable and speedy (I also have JIT installed). My experience that anything over 1000mhz begins to get unstable and you have to jack the vsel way up (more battery usage). Also, replacing the homescreen launcher really helped (Launcher Pro, ADW, etc) because the stock one really kind of sucks.
If my carrier comes out with the Nexus S in March as the rumour is - I might move over to that as I'm sure it will continue to be supported and none of the this 'staying on 2.1' BS will happen. But we'll see if and when my carrier does that...and how much it will cost.

$700 to $800 CDN
$699.99 at best
now back on topic, the XT720 at 1000 Mhz runs really nice, even on stock 720 Mhz runs good with Launcher PRO or Go Launcher EX
heavy 3D games runs fast, everything else runs great
so i really have no idea of those 3 people that have complained about the phone.
they might have not configured something right
Indeed AllGamer.
The phone is really fast here when overclocked to 800 Mhz or 1000 Mhz. Angry Birds lags somewhat at 800, but at 1000 is runs great. Also HD Video Recording runs the best at 1000 Mhz, but I don't care. Also, I noticed that when HD Video Recording at 1000, the battery doesn't use more than at stock. And 800 also doesn't use more overall.
I really love this phone and I won't be selling it for a long time (and my next one will also be a Motorola, I'm a Motorola-fan for years now, although I had a few other phones though between my previous Motorola and this one).
So people: please configure it right, 'cause this thing is really speedy when overclocked
I have to admit, that my xt720 runs absolutely fine..angry birds and any other game i've tested are totally smooth - only hd-video recording becomes a bit stuttering ( is this correct english? ^^) sometimes. And until now no JIT or apps2sd is installed
Sent from my Milestone XT720 using XDA App
wat nid to imporved in xt720 froyo is:
- camera software (increase img quality)
- custom kernel (enable swap space, prepare for future games)
- greater space for cache (enable installation of battle bears -1.apk)
- stock oc to 1.1ghz (battery life can extended by setcpu)
- DEfy's stock music player
- xda xt720 special bootscreen (required a talented graphic designer)
xt720 ll be perfect..
wrong thread...sorry.
It's possible that the Motoroi is not as stable as the XT720 at 1GHz. The XT720 has a TI OMAP3440 (officially rated 800MHz) and the Motoroi has an TI OMAP3430 (officially rated 600MHz).
Stay away from this phone. The small memoy 256MB is really laggy when you have more than 1 widgets and/or running multiple applications (running overclock at 1000 already). Also, 2.1.... who would want a smartphone that doesnt keep up? Not exactly smart is i?

Trolling?
Seriously, the memormy may be small, but you're exaggerating here. It's not laggy at all with more than 1 widget and multiple apps open (even w/o overclock). And 2.1, alright, but Dexter is working on the 2.2 port and he's gonna throw out a bèta one of these days. So 2.2 is on it's way and if the kexec crack starts to work good, then we could also have newer android versions later this year. So updates are not a problem for now.
To the TS I'd say: throw away that Wave and get yourself the XT720 It's a really good Android-phone and like AllGamer says: not the top of the line, but it sure can keep up and the camera is really good, hardware too and it just does what it does and that's what a phone needs to do IMHO: do what it does.
But indeed, check the MHz to see if it's compatible.
With JIT, we beat stock Samsung Galaxy. It is unfortunate to be cheated by Motorola, but this phone is a good piece of hardware and sure a head-turner. I have done what Link2SD did, move apks to an "ext3" partition of SD card, and with 1GHz OC, it feels snappy all the way.
I won't recommend someone to buy it new (just because of Moto's stupidity), but if happen to have it, do not regret.
i've been using xt720 for almost 4 months and before that i used milestone, galaxy s and some of LG and sony devices from friends... i can tell u the best touch-screen is in Moto(after apple ofcourse), the hardware is awsome, screen is a REAL scratchresist, the cover is strong and the backside cover is stable + looks classy. software is android as u know and always getting improved(we're about to have froyo from dexter-thnx to him-with all other functions). the speed? it workes so fine withOUT oc. for HD record or even faster actions u can OC it to 1ghz without any problem and even with oc battery life is almost same! besides that, if u turn off all wifi-3g and other web connections and 3d games stop showing ads inside nothing has lags at all!!
if u dont know how to use a new device, dont say bad things about it!
i have samsung galaxy spica (i5700) which has only 168mb of ram and 800mhz processor clock,with several widget its still running well,still has a smooth scrolling,compare with xt720,xt720 device is fastest than samsung spica although its has only 50mb of free ram on system

Dual Core Dual Channel but only running on 1 core??

Howdy everyone,
i happened to come across an app on the market called CPU Gauge and this demonstrates to you exactly what each core on your phone is doing at all times, even in your notification bar at all times. Now i have noticed no matter what i do there only ever seems to be 1 core running which is pretty pants i reckon. how can i enable it to run dual cores all of the time? i dont understand it personally, why have a dual channel architecture if its hardly ever used? and surely it having to decide whether to use one core over two and to send data down both channels or just the one is probably a reason why we get lag? i am probably completely wrong but id rather the cpus always be on and drain battery if it improves overall performance

Though a mod will move this thread please post questions in the general section this is for development purposes only..
But if what you say is true i will have to look into this. What rom are you currently running?
Just a rooted/overclocked LG stock gingerbread rom.
For me it shows 2 Cores working ,but second is ON only when needed (as it should be) So its OK. Lags are because of poor ram managment on LG software, I recommend Rushdroid ROM.
What I know, Android 2.3 and below does not provide a support for multi cores. However, ICS does support it. So, I think the phone will run much better when the ICS update comes.

nope. thasts only an urban legend But it can improve performance at some points, but I would be rather sceptic. Custom roms must be always better (what they are doing making software, making it slower on purpose? go Samsung way and hire cm team members)
In games it uses both cores but im dissapointed that when testing swapping between different apps and web browsing seemed to all be using just the one core, and that was with lags inbetween swapping from for instance gallery to browser. I love this phone great specs but it annoys me more and more to think LG really did have no clue when it came down to putting it all into action. is there any way to have 2 cores on at all times or atleast change the values that decide when to use second core/channel.
If anything it makes for an interesting discussion

It has a partial support, not 100%, and the proof is that all dual core phones which received ICD update, got a huge improvement in the performance, as their users said.

The processor works as it should be, all cores when needed. Check System Panel app. Ram is the issue here. On stock it will be always laggy. On rushdroid and samba there is good ram management. Almost 250mb for the user. On stock i doubt if there is 130mb free available.
@up: there is no evidence that GB supports 1 core only and ICS multiple cores. A better performance on ICS can be due to the bigger optimizations, and hw support (that can be buggy) like gpu enabled scrolling etc.
But Ive heard that ics supports fully multicores, and that is an urban legend for me (no evidence) Ics can be just more optimized than gingerbread (and more like honeycomb which was quite fast)

you are correct cores are working as they should be not a problem here at... Gingerbread supports multicore and does use the cpu to the max when needed, you don't need to run both your cores all the time if that was the case you would need to charge your phone every 3 hours....
The issue with our optimus 3d is it needs ram tweaks to keep it smooth, 512mb ram is good i am not complaining because it's dual channel and so on so the ram speed is amazing just to free up ram we have tweaks...
Also the cpu is used to the max when needed, when you make a call you do not need both cores working at the same time that would be pointless. But when you play games, browse the net and bench your device all cores are used at the same time...
if you want to try it (see the difference) with both cores enabled ,(and cpu speed at max) try system tuner app , in cpu setting put governor to "performance" the first core will go to max speed , then go to active tweak and there is an option to force all cpu on , try it , it will be hard for the battery... when you put governor back to hotplug , the second core will return on demand (on/off) . if you want to do it again after you have to redo all step and turn the force all cpu on off and on again...
i'm on v21D on rushdroid 3.6.3. Both cores show up as working. 1 core ususally hits 1.4ghz and 2nd one upto 1ghz during regular processing. Great app btw tnx for letting us know
Which kernel you use on rushdroid @1,4ghz?

Its not neccessary to use dual core all the times ,using dual core for small task degrade the performance that increasing. Since our phone have dual memory the cache plays an important role in deciding which core should be used.

[Q] Benchmark and over-clocking

so I just ran a benchmark and recieved a score of 6193. Is this pretty normal to what you guys are seeing? Im running setcpu, but also had a quesion about these over-clocking apps.....being that the 10.1 sch-i925 lte is a quadcore, are the normal over-clocking apps still as efficient and can handle a quadcore?
Just asking....have a major in computer science, but that was 2 decades ago and now I dont work in ther industry, but I do play with my pc and smartphones and now my new tablet, so I am still kindof litterate.....but as far as coding these things, Im clueless, and not sure how these apps are written and if they take into acount a quad core vs dual cores or single.
I alos have a speed card reader app, dont know if this effects benchmark results, but just thought Id put that out there. So what kindof numbers are you guys seeing? Or anyone that can help educate me better about what Im talking about feel free to help me out.
Thanks guys
