[Report] Hardware Tessellation test on android failed. #9234

xebra · 2017-01-25T01:00:21Z

Just simple report.
I tried auto-built v1.3-321-gce2feb2 but it's failed with Hardware Tessellation.
I hope to fix it but I don't know how to fix and debug with android.

Tested bezier in pspgl on ZenFone 5(Android 4.4.2)

zminhquanz · 2017-01-25T01:25:46Z

you can install aLogCat to view debug logging

xebra · 2017-01-25T01:42:42Z

@zminhquanz Thank you for the information. I'll try it later.

xebra · 2017-01-25T02:17:16Z

Hmm, I don't know how to use this app...
I want to find ppsspp's log of developer mode. Where can I find it?
I don't know about android well...

zminhquanz · 2017-01-25T03:11:08Z

@xebra enable debug logging in tools -> developer

zminhquanz · 2017-01-25T03:21:16Z

i don't know how to tell you to understand , wait @hrydgard going to tell this

LunaMoo · 2017-01-25T05:12:44Z

On android everything(this means other apps as well) logs to one place and there are apps which you can use to read it directly from your phone or it can also be read on pc. Last time I had to check a shader I used "CatLog" app, note you don't have to(nor want to!) change any logging options in ppsspp to debug a shader, debug log will not give you anything more since shader errors are very verbose already and would just spam the log.

Just run ppsspp, run your test app to fail a shader compilation / hardware transform, then pause, press home button and launch the CatLog app to read logs, you can pause logging in it and filter the results for NativeApp which will show you ppsspp logs hiding everything else and hopefully expose some useful errors.

General problems with shaders on android are dumb drivers with very poor compilers. This means 3 things:

your code has to follow exact glsl specs without any shortcuts, it's likely impossible to test on pc since even shaders tested with official glslangValidator can fail on mobiles due to bugs or other weirdness:|,
it also means shaders has to be optimized by hand if you care about optimizing them because mobile compilers will not do that, they'll just literally just eat what you feed it with and produce s... ;]
some older gpu's can just fail to compile shader based on it's size;p.

Checking http://report.ppsspp.org/logs/kind/39 newer errors seems to be related to tesselation. And ugh lots of them, but most seems to be just dumb int/float conversion/overload functions which is exactly something that desktops drivers will interpret correctly, but doesn't really follow glsl specs where you have to cast ints into floats etc. by hand for example if function expects (float, float), something like (1, 2) is incorrect, but interpreted on pc's just fine, for mobiles we have to (float(1), float(2)).

hrydgard · 2017-01-25T09:06:24Z

Or just 1.0, 2.0. Looks nicer than float(1) etc.

LunaMoo · 2017-01-25T09:36:04Z

Yeah, I was giving an example in case of variables.:3

xebra · 2017-01-25T09:55:26Z

@LunaMoo Thank you so much for your explain with details. I understood a little about android system.

General problems with shaders on android are dumb drivers with very poor compilers. This means 3 things:

Hmm, I think it's very hard to fix them. If I could fix it on my device, but others...
Anyway, I appreciate your help :)

BTW, I'm implementing this on DX9 but still something a little buggy...

hrydgard · 2017-01-25T10:42:49Z

If necessary we can just turn off the feature on Android, or whitelist certain devices.

xebra · 2017-01-25T11:13:09Z

Yeah, you right.

LunaMoo · 2017-01-25T11:15:30Z

Would be much easier if there was a tool that simulate the awfulness of mobile gpu drivers on pc.
Khronos reference compiler is so far best tool I tried to debug glsl code aka fails to compile most stuff written for pc's. Can just save a shader to a file and run it through this compiler to catch most problems, but from my experience with post process effects it unfortunately still can pass stuff that doesn't work on smartphones.

And yeah I would be for just disabling it there as well. People are excited by "hardware tesselation" for various reasons primary being the screenshots comparison showing fps difference and missunderstanding caused by it. This isn't free speedup, it shifts heavy work from cpu to a shader - really nice for most typical pc's, gles devices however are nowhere close:].

Edit: I was just checking the vertex shader generator code and shouldn't it check for and enable GL_EXT_gpu_shader4? Most of that code seems to need it, we could also maybe disable it for all devices that doesn't support it. There's also gl_InstanceID which requires minimum gles 3.00.

brujo5 · 2017-01-25T20:09:03Z

Work great in my galaxy S6

LunaMoo · 2017-01-25T20:20:44Z

So you actually checked game which uses this code or the test homebrew?

Meanwhile I found a way to reproduce the problem on pc;p linux under virtualbox - yay for poor gpu/drivers.

Log from test homebrew:

So mod() fails and expects floats since as with my edit above integer math requires GL_EXT_gpu_shader4, so that's one thing we need to check and enable. Not doing that could probably be the reason why it failed for the person with nvidia gpu on win 10 reporting in merge thread. Another problem is gl_InstanceID which requires gles 3.00 or if someone really cares, it could also work on older iOS with some apple stuff, probably not worth.

Guess both of those could be supported on new higher end smartphones like mentioned GS6.

mrcmunir · 2017-01-25T20:31:14Z

Not working also in mesa3d 17.0 intel driver Opengl es 3.0

ghost · 2017-01-25T20:46:30Z

New build (1.3-388) tested, break some textures in NFS MW and bornout legend.
hardware:
Armv7 neon
Mali-400

mrcmunir · 2017-01-26T02:54:15Z

In mesa3d intel driver under linux Workaround fix needed Force Compatibility core because by default run 130 GLSL unsuported for gl_instanceID

https://www.opengl.org/sdk/docs/man/html/gl_InstanceID.xhtml

export MESA_GL_VERSION_OVERRIDE=3.3COMPAT

That function only avaible GLSL 140 and higher in the Opengl Desktop

@LunaMoo Your cooperation is really appreciated.

Can just save a shader to a file and run it through this compiler to catch most problems, but from my experience with post process effects it unfortunately still can pass stuff that doesn't work on smartphones.

I didn't know that, I'll try to check it out.

Ah, yes, I forgot it.

Meanwhile I found a way to reproduce the problem on pc;p linux under virtualbox - yay for poor gpu/drivers.

I was thinking similar situation like Android emulation on Android Studio or something but I didn't realize that. Linux on Virtualbox seems good solution.

Log from test homebrew:

It's very useful infomation! thanks :)

xebra · 2017-01-26T03:05:22Z

@brujo5 I'm glad to hear your report :) Thanks!

@mrcmunir Thank you for the log and information, it's very helpful for me.

@Ar37 Thank you for testing and reporting.

zminhquanz · 2017-01-26T04:14:20Z

because hardware on mobile is different ( GPU like Mali , Powervr , Adreno , Nvidia ) , and is having problem graphic

mrcmunir · 2017-01-26T04:54:12Z

@xebra you're welcome and also with llvmpipe driver like virtualbox/vmware too work
I think mesa3d based drivers are implemented GLSL 130 you can force Opengl 3.3 with that command 👍

xebra · 2017-01-26T09:07:23Z

I pushed DX9 version(still incomplete).
So I'll try to fix again about GLES.
@zminhquanz @mrcmunir Thanks again for the infomation :)

DonelBueno · 2017-01-27T12:07:51Z

Is it fixed? I don't have a device to test.

mrcmunir · 2017-01-27T12:27:21Z

In my Adreno 305 GPU compile shader no see any error in the log but has flickering and glitches errors.

Later try with Mesa3d Opengl es 3.0 if working ok.

Edit : Yes With mesa3d drivers working very well

LunaMoo · 2017-01-27T13:55:19Z

It still can fail to compile due to gl_InstanceID.

For GLES it requires shader version 3.00, for OGL it's 1.40 version. On lower versions the feature should be completely disabled.

hrydgard · 2017-01-27T14:04:27Z

Qualcoom (Adreno) is not known for good drivers...

mrcmunir · 2017-01-27T14:17:07Z

Ok well if I wait 30 seconds avg crash libsc-a3xx.so and libGLESv2_adreno.so driver fault
Let's see if I can capture the log and Upload it..

edit : ok The log is here :)

ghost · 2017-01-27T20:10:20Z

@hrydgard i thought newer adrenos are better?

xebra · 2017-01-28T02:34:02Z

Thank you all :)
@mrcmunir I have same gpu but it crashes when loading pspgl bezier.
However, PuzzleBobble worked fine, but second time run the game, it does not draw nothing about bezier. Maybe, it's shader cache issue, I think.

@LunaMoo Thank you for detailed information for fix this.

hrydgard · 2017-01-28T08:42:08Z

@abz1 They are, but from what I understand their shader compiler is still not exactly the best.

hrydgard · 2017-01-29T08:15:32Z

Now that #9249 is solved, did any of this start to work? :)

xebra · 2017-01-29T09:46:38Z

@hrydgard In my zenfone5, it can run only PuzzleBobble. Bezier in pspgl can not run because it crashes the app when starting.
Anyway, building issue and shader cache issue fixed, closing this thread.

mrcmunir · 2017-01-29T12:05:46Z

@hrydgard with Adreno device not work anywat is driver fault maybe need disable in Adreno 3xx series? In blacklist series v84 driver .

brujo5 · 2017-01-31T16:52:56Z

Why Tessellation is disabled in my galaxy s6?

I didn't experience any issue before.

Some user have problem with old mali400 but my device have mali t760 mp8 with sles 3.1

hrydgard · 2017-01-31T18:18:33Z

@brujo5 Sorry about that, the compatibility check simply needs to be refined. @xebra ? :)

mrcmunir · 2017-01-31T19:16:56Z

Also happen in mesa3d driver too not are avaible now with Opengl 3.3 GLSL .

@brujo5 did the v1.3-450-g052660b worked for you? (the last build before compatibility check)

I think it shouldn't, but instead being disabled it would probably break since Mali t720 doesn't have(?) OES_texture_float and it became a new requirement from some earlier changes. At least that's the only thing listed as required which seems to be missing on SGS6.

@brujo5 @mrcmunir Thank you for reporting, I tried fix the issue.

@hrydgard @LunaMoo Thank you for supporting me :)

xebra · 2017-02-01T11:23:46Z

I tried to fix it but it's not fixed yet.
So reopen this.

@xebra yep , I found for mesa3d drivers the fault is check for EXT_gpu_shader4 never can't supported and working without that function with GLSL compatible

@mrcmunir Oh, I just found same issue when I checked all extensions in my zenfone5.
I'll fix it soon.
