[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!

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 : /

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)

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

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.

Exynos UI Snappier than S600 or placebo effect?

After seeing dozens of vids i started to notice in Russians vids (Exynos Version) UI transitions seems to be more snappier than vids using S600 version.
In russians vids all in S4 seems pretty smooth and fast (like here and other vids: http://www.youtube.com/watch?v=2ymXQHSxOh4).
In s600 vids seemed to me have seen something clawing here and there.
Someone more have notice this or is just a placebo effect i have.
Thx.
I'm dying to see 2 versions face to face.

Placebo it's probably using the a7s anyway when UI browsing

That may be true, but the GPU is more power full so it could be faster due to that. I don't know, they both look good to me.

Also dont know, as i said after seeing many videos I found myself looking preferably Russians videos because what i saw in their S4 screens looks better to me than no Russians vids, although in beginning didnt associated they use Exynos version.
I hope is placebo effect because here we only have S600 version....arrhhhh SAM.

It's possible. Neither has the final SW out and Samsung has been working on the Exynos version before they realized they'll need the Snapdragon to meet all the demand. How quickly they managed to adapt with all features to a different SoC only means they'll improve it further upon launch and then some, but I can't say I've seen any lag on either version in videos.
The only thing's bothering me is the home button lag cause it waits for double input, can you turn it off?
Also, is there a way to make AirView pop-ups instantaneous like mouse hover instead of waiting a second over the content?

The Adreno 320 should be similar performance to the SGX544MP3 on the Exynos. Both of the chips GPU are clocked higher than stock, we know the SGX544MP3 is at 533Mhz. Plus in theory the Adreno 320 still should perform better due to better intergration in the GPU. The Adreno 320 has more to offer than the SGX544MP3 in the long run such as OpenGL 3.0 and Open CL 1.0, which should make the UI smoother.
Anyways, I won't be surprised in the Exynos version is more optimized, the A7 CPU is a lot slower than the Snapdragon 600, so they'll have to make it optimize for the Exynos chip than the S600.

With 2 GBs of RAM, who knows how many things are running and what is on the priority list. Those are things we don't get to see in these videos.
I wonder if lets say having 5 memory intensive apps open would bog down the CPU priority list and slow the device down a bit.

First comparative says the Octa version delivers 10% better benchmark performance to the Snapdragon 600 variant
......
and better battery life.

Don't bother with battery comparisons on the i9500, the phone is unfinished.

So I got my i9500 and already did some foolery with it.
Fine device, but I hate the raised lip around the screen edge. Something I definitely did not miss on the S3 and something very annoying.
Other than that small design critique:
THE ****ING PHONE ISN'T RUNNING FINAL FIRMWARE!
Basically the CPU is running on the cluster migration driver, meaning it switches all four cores from the LITTLE to the big cluster, as opposed to the core migration driver who does this in an individual core-pair manner.
You can pretty much throw all battery comparisons out of the window: it's completely unfinished and unoptimal.
I already compiled the kernel and flashed it without the cluster migration tidbit, but the phone won't boot. So yea. Current sources also useless.
Cleverly enough: you can't really distinguish between the two drivers apart from one manner: if /sys/devices/system/cpu/cpufreq/iks-cpufreq/max_eagle_count is present, you're running an IKS driver. If it's not, then you're running the sub-optimal IKCS driver.
So yea. We'll see what Samsung does about this, currently the advantages of big.LITTLE are pretty much unused.
Another nail in the coffin on how rushed and unprepared this phone has been.

Wow, this is seriously turning out to be a fiasco.

Question is now: Is this possible to fix in the near future?? So that maybe buying the Exynos will be beneficial if the devs take over. I wont bet on Samsung introducing mind-blowing improvements in that department in upcoming firmwares

The code other driver is there in the kernel, it's just not used. No idea. It's not like we need Samsung for it: I already talked to a developer at Linaro about some incomplete switcher code that's being currently getting the green-light to be made public. But who knows how long that will take.
Whatever the case, I gather that they can't just let it be in the current state.

Any way to just disable cortex a15 altogether yet just to see how well cortex a7 will perform in simple texting, browsing, calling and to see what the battery life will be like on that?? (cause cortex a7 only uses like 200 something mw as opposed to 1000mw for snapdragon). I know u wont be able to game. How often does Cortex A15 hits in? cause I would suspect a much worse battery life with incomplete drivers doing the switching if its very often on. But PocketNow reports very similar battery results to snapdragon variant which I find odd

Use any app to limit the CPU frequency to 600MHz. That'll limit it to the A7 cores running to 1200MHz. Basically you can just use CPU-Spy. Everything <= 600 are A7's mapped at half frequency, everything above it are A15's at 1:1 frequency.
As for PocketNow: irrelevant. The difference is what could be instead of what is, the Snapdragon doesn't play a role in the discussion here.

WOW , thats sucks
Samsung was too rushed and ruined it :/

Hey thanks, but I don't have the S4 to test it with since i'm still debating on which to get. I live in Canada and so the only version here which I can get a lot cheaper on a contract is LTE snapdragon, but I wont mind getting the Exynos since it got potential. Besides 16GB internal isn't enough for me. So that's why asking if u seen any improvements in battery when only cortex a7 ran? If a7 doesn't do much in power consumption, then no point spending 800 bucks and loosing LTE altogether...

Is it possible that we're having a simpler Exynos 5 system technically closer to Exynis 5 Quad (plus 4 A7 cores) than a real seamless Octa-core system? It was strange reading that "Octa-core manufacturing starts in Q2" (April-June) then see Octa-core versions hitting reviewers early April, that's way too low time frame. Maybe this is a 1st-gen 5410. In any case, performance and current-state battery life beats the Snapdragon version, even if only just.

WHAT THE [email protected]??!!
Actually WTF is a massive understatement here....!!!
Please can you give more info about this matter whenever is possible? This is very serious...
Is it a specific hardware limitation? Something that Samsung specificly did in GS4 (I9500) ?
Because this can't be a generic exynos octa limitation. It makes no sense... Unless everything we've read from Samsung and ARM about exynos octa, are completely misleading...

A hardware limitation..? They advertised the functionality and to then release a device without it, is just plain stupid. Hopefully it is a just a kernel issue and can be resolved quickly.

Probably Samsung will implement it in their Note 3 device? It's a conspiracy so that people buy their next Note phone but this news is sad.

Now what is this all about? Is this a very serious issue?

So its either all A15s or all A7s?
so would the 'octa' really be a better choice than the S600? That should be powerful enough.. and the S600 is pretty power efficient too

What I understood is its either the full cluster of a7 or a15 is used/ functional based on the load, dynamically turning on one or two cores of a15 to work along with a7 may not be possible it seems.
I may be wrong, waiting for an elaborate exp from andrei

I was always under the impression this was the intention of Samsung's particular implementation of it. I thought it was common knowledge that Samsung's version worked on a 4 or 4 (A15) or (A7) basis.
Maybe he was talking about the ability to change that.

Root/Roms for Mode MP1 phone

I got a Mode MP1 phone (Dual Sim) which is supposed to pay for ads and watching videos, etc. I am trying to get rid of the stock ad-filled rom. Searched and couldn't find much for that phone.
Device Name: MP1
Model: MD_G1212U
Build Number: EarnUI_1.4
It appears to be a generic CN phone, looking on google search and finding other different brands that looks identical. Any help is appreciated.

Heap of junk. I saw the ads as well and figured id take it for a spin see what the phone was like and if there was ever a chance any money could be made off it. Ive had it for months now and its collecting dust. Should tell you how much i like it. However I guess im going to go through with learning its chipset though as UNISOC / Spreadstrum chipsets are new to me. I read they are super easy to work with and build for. As for firmware and rom's if i find anything or build something ill let it be known here.
EDIT: The phone is actually a branded Veviview or something like this.. I forget the name. I don't have a diag readout in front of me from Hydra Tools else i could tell you.

Yeah, I tried it and it is loaded with ads. I am hoping I can root to clean most of this at least or a whole rom of someone else has it.

I have the same phone. Had this since July of 2021 and barely made $60 now, but I barely use it besides watching my movies from my plex server...
I was wondering how I would go about pulling the from of the phone for general backup purposes and maybe be able to get a root for the device. I know a lot of china devices are based on other similar devices and was figuring we would be able to get SOMETHING ported to this phone instead of letting it stay an ad-ridden heap of crap. Rather debloat and slim this phone up, maybe port a rom from another device to it.
Besides all that, this is what I have from the device so far through AIDE64 (left a few things out that I figure were non-essential):

From what I have figured, getting into the device would mean we would have to use the SPD Upgrade Tool or SPD Research Tool? Im familiar with MediaTek devices, kinda, but this chipset is raw territory for me. Mediatek allowed you to pull your whole from as a ROM0 backup and then there were tools to be able to unpack it also. SPD seems to NEED the firmware.pac? Not exactly sure.
If someone can point the way, I'm willing to make a 1:1 of the from and post it if possible.
Thanks in advance, and if nothing can be done, at least there is some more info on this phone.

Haven't found anything or had a moment to toy around with the device. It's sitting collecting dust at the moment. Has a strange rebooting issue. Reboots at random and last i checked every 20 seconds after booted up.

Hello guys did any one know if i can do FRP for Mode MP1 and where?

I sold mine as phone is too slow for me. However If I do get it back / buy a new one I will look into working on it. Although during its lifetime here I did get some very cool "access to area" abilities on that SOC.
