Voodooi2c: Laggy trackpad after polling optimisation commit

[marianopela]

Trackpad is laggy after https://github.com/alexandred/VoodooI2C/commit/6087df30dec3fa1dd1e5cf0763c3d8c73822e8b9

@kprinssu @lvs1974

log (3).txt

For comparison, this is with previous kexts

I'm not sure these gifs are showing the difference (they are somehow slower that the original video), so here are the two videos
Archive.zip

[kprinssu]

@lvs1974 can you please take a look at this?

[lvs1974]

@kprinssu: yes, sure!

[lvs1974]

@marianopela, thank you for the videos and log.
It looks quite strange. And there are a few messages in the log.
Could you try attached version, please?
It is compiled for 10.15, if it is not ok, please let me know.
Release.zip

[marianopela]

@lvs1974 you're more than welcome and thanks for your work

It seems much better now and may have a normal behaviour. I can't really tell if it's normal or not, so I assume it's good enough for me

Here is the comparison (where new are these kexts you just provided and old are the ones I had since 2/3 days ago)
new.zip
old.zip

What did you change now?

[Mateo1234454545]

Drag and drop is buggy. Doesn't work all the time.
Also if left click is pressed , cursor freezes for 2-3secs and then behaving erratically.

[lvs1974]

@Mateo1234454545, it is not clear from your log which mode is used: interrupt or polling.
It looks like "log show" skips some log statements.
The most reliable way to get logs:

• add msgbuf=1048576 into boot-args
• in terminal use sudo dmesg | grep -i voodoo > ~/Desktop/log.txt

BTW: did you rebuilt VoodooInput from the latest acidanthera sources, some drag-n-drop issues were fixed there.

[lvs1974]

@marianopela, thank you!
What I actually did:

1. moved updating of last_multi_touch_event from VoodooI2CMultitouchHIDEventDriver::handleDigitizerReport to VoodooI2CMultitouchHIDEventDriver::handleInterruptReport, otherwise it can be skipped,
2. VoodooI2CHIDDevice::simulateInterrupt calls IOSleep(1) and checks whether last_multi_touch_event was changed and if it's the case, sets short timer interval immediately.

[marianopela]

BTW: did you rebuilt VoodooInput from the latest acidanthera sources, some drag-n-drop issues were fixed there.

@Mateo1234454545 I'm on latest VoodooInput (from the last commit 10 days ago) and no problem at all with drag-n-drop nor with left click
Try this
VoodooInput.kext.zip

[marianopela]

@lvs1974 Well done. Let's wait for @Mateo1234454545 to have confirmation

Edit: I asked a friend on 6th gen cpu and elan trackpad to test. It works well for him too
I'll wait a bit for @Mateo1234454545 and close the issue

[lvs1974]

@marianopela, thank you for testing and for asking your friend!

[Mateo1234454545]

@lvs1974 @marianopela , tried but still the same.

Here is the new log :

[lvs1974]

@Mateo1234454545, this issue does not have any common with interrupt mode.

[Mateo1234454545]

@Mateo1234454545, this issue does not have any common with interrupt mode.

Yes ,but somehow it affects it. I didn't have this problem with previous commits.
For example , this is working just fine :
VoodooI2C.Mar.27.zip

[lvs1974]

@Mateo1234454545, very likely it is related to another commit:
https://github.com/alexandred/VoodooI2C/commit/2fdbedb4beeb1583fb911867b648a91d1abd38ee
Please try to update VoodooI2CHID to commit before 2fdbedb4beeb1583fb911867b648a91d1abd38ee, rebuild and check.

[Mateo1234454545]

Thank you, but I don't have the required skills to build voodooi2c. I'm always getting errors.

[lvs1974]

@Mateo1234454545, then replace one kext and test again.
VoodooI2CHID.kext.zip

[Mateo1234454545]

@Mateo1234454545, then replace one kext and test again.
VoodooI2CHID.kext.zip

No , still the same problem.

[lvs1974]

This VoodooI2CHID built for revision dd16dd9d10a23580e1aa2572a1b25568ba7a354f, when I actually did not changed anything. It means the issue is not in VoodooI2CHID.
I built VoodooI2C for revision 2c89682d7e207386a84e98d5173c505855e25479, try it.
VoodooI2C.kext.zip

[Mateo1234454545]

No , doesn't solve the problem.

[Mateo1234454545]

I'm guessing it has something to do with voodooGPIO.

With the version working OK for my trackpad I'm getting these errors #264

Still the same

[lvs1974]

@kprinssu, I have no idea what is the problem. I checked out revisions without my fixes, but problem still exists, Could you have a look, please?

[kprinssu]

@lvs1974 @marianopela I suspect it's either of these changes that I merged in from @Erictoby:

• VoodooGPIO (https://github.com/alexandred/VoodooGPIO/commit/3f42a0b99543f04673d7b8b38fe64a0aef2fb30a)

The IOWorkLoop was removed and I suspect the parent IOWorkLoop is getting backed up with the interrupt requests. It's causing a bottleneck when the "interrupt handle" threads are waiting on the loop.

Can you guys try reverting that change and see what happens?

@lvs1974 can we chat via iMessage?

[lvs1974]

@kprinssu, thank you for suggestion.
I took VoodooGPIO: 8507d8ddb0c057d46c111ed20ff4126e5212c017 (1 Nov 2019) and removed getWorkLoop method.
@Mateo1234454545, could you try, please?
VoodooI2C.kext.zip

[Mateo1234454545]

@Mateo1234454545, could you try, please?
VoodooI2C.kext.zip

That's it.
Everything seems fine. I will keep monitoring.

Can I ask something?
Is voodooinput.kext necessary ? My touchpad works the same without it.

[kprinssu]

@Mateo1234454545 you definitely need VoodooInput, otherwise your trackpad won't send the touch events to Apple's MT stack.

@lvs1974 can you please create a PR, I'll merge it in ASAP and close this ticket.

[Mateo1234454545]

@kprinssu , problem with drag and drop solved. But touchpad feels a little less responsive.

[Mateo1234454545]

And I don't think @Erictoby's commits are the problem.
Without them my touchpad was very laggy.

[lvs1974]

@kprinssu > can you please create a PR, I'll merge it in ASAP and close this ticket.

I don't quite follow you. PR for VoodooI2CHID is ready.
VoodooGPIO it is a different repository (where getWorkflowLoop() should be removed).

[lvs1974]

@Mateo1234454545, could you test one more time, please?
And put also the latest build VoodooInput (was attached here previously).
Release.zip

[Mateo1234454545]

Tried but problem with drag and drop is back.

[Mateo1234454545]

And there is problem with 2 finger scrolling (e.g. os safari). Sometimes freezes.

[lvs1974]

Ok, and with this build (latest sources + added getWorkLoop() method):
Release.zip

[Mateo1234454545]

Scrolling working.

Drag and drop works but it seems too sensitive.
For example when you drag and drop a file , it does ,but when you release the touchpad the file is selected for rename , like you double-clicked on it.

[lvs1974]

@Mateo1234454545, could you try this VoodooInput + VoodooI2C + VoodooI2CHID:
VoodooInput-1.0.4-RELEASE.zip
Release.zip

[Mateo1234454545]

@lvs1974 , it is worse than before. Drag and drop almost not usable.

[lvs1974]

So, It proves that VoodooInput also has big influence on that issue.
Try to replace only VoodooInput.
I don't want to use this strange method getWorkLoop(), anyway it is not reliable.
VoodooInput.zip

[Mateo1234454545]

Better than the previous , scrolling is ok.
But drag and drop is buggy.

[lvs1974]

@Mateo1234454545, can you test a polling mode, please?
After I will buil one more Voodooinput.

[Mateo1234454545]

I used geni2c to generate polling mode , but my tuchpad didn't work
Don't know how to do it.
Here are my files if you you have the time to try.
files.zip

[lvs1974]

@Mateo1234454545, could you try this one:
VoodooInput-1.0.4-RELEASE.zip

[lvs1974]

@Mateo1234454545, I also have a question regarding your version VoodooI2C Mar 27 (you attached it before in this topic).
Did you build it yourself? On 27 March, from master? With all current (for that moment ) submodules?
It seems very strange for me that it can work without VoodooInput.kext: on 22 Mar VoodooI2CMT2SimulatorDevice.cpp was deleted, so all versions built from master after 22 Mar cannot work without VoodooInput.kext.
We need to find some point, where I can build VoodooI2C with Satellites, and this build will work stable on your machine. For example, what if I get sources from master for Mar 24, 2020 and build version. Will it work without any lags on you laptop?

[Mateo1234454545]

No drag and drop still very buggy. Also , three-fingers swipe doesn't work.

The build of 27March I found it on daliansky's repo.
Even the files you are sending me are working without voodooinput.kext

For your last question , my touchpad worked ok until release 2.1 (if I rememer correctly). All the releases after made my touchpad freeze for about 2-3secs. I had to use @Erictoby's release which worked very well.
Untill @daliansky's 27Mar release which is also working very well. But I don't know what commits are on there.

[lvs1974]

@Mateo1234454545, in that case this is a wrong way to find a root cause.
Since release 2.1 related to this master branch there were a huge amount of commits, and it is useless - try to find something with the latest sources.
I think you need to contact to @daliansky in order to find out a branch and exact date (or even better exact revision) of sources used to build this version. It can be something completely different, with specific set of patches.

[williambj1]

@Mateo1234454545

Could you please clarify which repo did you use to get the files? I've sent several versions of VoodooI2C to Daliansky I built recently and I can track the version.

P.S. People in Daliansky's chat group didn't have the proper skills and environment to build the kext.

[Mateo1234454545]

https://github.com/daliansky/XiaoMi-Pro-Hackintosh/issues/362#issuecomment-605099261

[lvs1974]

@Mateo1234454545, if your touchpad works even without VoodooInput, it means it supports PS2 interface, and probably kexts from VoodooPS2Controller.kext (VoodooPS2Trackpad.kext) are working in this case.
My touchpad does not support PS2 interface and does not work without VoodooInput kext.

[williambj1]

Ok, this was compiled by steve, I thought you used the version from the XiaoXin repo, I'll contact him ASAP.
CC @stevezhengshiqi

[Mateo1234454545]

Great.
@lvs1974 @williambj1 , if you want please help me try polling mode at gitter.

[lvs1974]

@Mateo1234454545, it seems your touchpad is configured improperly for interrupt mode.
What is your hexadecimal APIC pin number, 0x33 or something different?
You did not change gpio pin number also.
Your _CRS method returns something unknown, it depends on variable SDM0, but for interrupt mode it should always return Return (ConcatenateResTemplate (SBFB, SBFG)).
May be you should try to do setup of your touchpad from scratch?
Perform GPIO pinning - find out pin number and so on...
https://github.com/alexandred/VoodooI2C/blob/master/Documentation/GPIO%20Pinning.md

[stevezhengshiqi]

@williambj1 I believe I use VoodooI2C v2.3 + https://github.com/alexandred/VoodooI2C/pull/254 and the VoodooI2CHID until commit https://github.com/alexandred/VoodooI2CHID/commit/2f6537709c51743fde943804eee0e65642762277. I am not so sure about that. Some latest commits also break my trackpad so I reverse back a lot of commits.

[lvs1974]

@Mateo1234454545, from your config I also found out:
Your proper device name is TPD0 (according to ioreg), and you set OSYS to 0x07DC in SSDT-TPD0.aml, but what about SDM0 value? Who knows what is stored in this variable?

I do not have IOInterruptSpecifiers so I procceded on installing the kext.
My gpio pin is 0x1b
Screen Shot 2020-04-04 at 17.13.07.pdf

[lvs1974]

@Mateo1234454545, but what if you boot without VoodooI2C and check ioreg? IOService, TPD0?
Is there IOInterruptSpecifiers?

[Mateo1234454545]

Without it my APIC pin is 0x33.
I tried to follow the guide but I'm very confussed.
My dsdt if very messy.
Any help would be appreciated.

[lvs1974]

@Mateo1234454545, if you APIC is 0x33, it means your GPIO pin 0x1B (default in DSDT) is wrong.
And your interrupt mode works incorrectly.

For hexadecimal APIC 0x33 us can use my calculations (I also have 0x33):
hexadecimal APIC pin number = 0x33

GPP_B3_IRQ = 0x33 https://github.com/coreboot/coreboot/blob/master/src/soc/intel/cannonlake/include/soc/gpio_defs_cnp_h.h#L42
GPP_B3 = 28 https://github.com/coreboot/coreboot/blob/master/src/soc/intel/cannonlake/include/soc/gpio_soc_defs_cnp_h.h#L74
GPP identifier = B

CNL_GPP(1, 25, 50, 32),             /* GPP_B */    https://github.com/coolstar/VoodooGPIO/blob/master/VoodooGPIO/CannonLake-H/VoodooGPIOCannonLakeH.hpp#L416
num, base, end, gpio_base

28 - 25 (base) + 32 (gpio_base) = 35 = 0x23

GPP_F3_IRQ = 0x33
GPP_F3 = 219
GPP identifier = F

CNL_GPP(3, 216, 239, 288),

219 - 216 (base) + 288 = 291 = 0x123

GPP_J3_IRQ = 0x33
GPP_J3 = 290
GPP identifier = J

CNL_GPP(3, 287, 298, 352)

290 - 287 (base) + 352 = 0x163

you also can try some of the common values such as 0x17, 0x1B, 0x34 and 0x55.

Everything is described in documentation for VoodooI2C.
Please read it!

[Mateo1234454545]

@lvs1974 , thank you again.
I really tried but I cannot manage it.

[lvs1974]

@Mateo1234454545, you should add a following ssdt:
SSDT-I2C.dsl.zip

You also need to remove SSDT-TPD0.aml from config.plist.

But you also need to patch your DSDT:
GPIO: change _STA to XSTA in device GPI0 (TouchPad I2C), pair with SSDT-I2C.aml

A4 52 42 55 46 14 1D 5F 53 54 41 00

A4 52 42 55 46 14 1D 58 53 54 41 00

I2C0: _SB.PCI0.I2C0._CRS to XCRS, pair with SSDT-I2C.aml -> Touchpad fix

5F 43 52 53 00 A0 0E 95 4F 53 59 53 0B DC 07 A4 53 42 46 49

58 43 52 53 00 A0 0E 95 4F 53 59 53 0B DC 07 A4 53 42 46 49

After applying all of these fixes, reboot and run MaciASL.
You should be able to find method XSTA in GPI0, and method XCRS in I2C0.
If you can find them - patch worked and new methods from SSDT-I2C.aml replaced them.
Then run IORegistryExplorer, find TPD0 and check whether gpioPin is 0x23.

[Mateo1234454545]

First , I had to change i2c1 value to i2c0 and tpd1 to tpd0 in ssdt-i2c.aml , since these are the correct values from my trackpad. Right?

Geni2c shows touchpad in interrupt mode with pin 0x23 , but touchpad not working at all

Sending system dsdt with maciasl and ioreg.

@Mateo1234454545, yes that is right - you need fix names.
Please get logs with dmesg (sudo dmesg | grep -i voodoo), and size of msgbuf into boot-arg (see in this topic). You will see much more info:

I don't understand what the problem is. Tried all other pins but nothing worked.
In settings touchpad settings appear correctly.

Tried with opencore , too.

@Mateo1234454545, I have read manual one more time, and I have found a difference:
you have Sunrise Point, and I have Cannon Point-H. For Cannon Point calculations are different.
So, your right pin numbers: 0x1B and 0x7B. You can also try 0x17, 0x34 and 0x55.
So, 0x1B was correct value, sorry.

[kprinssu]

@Mateo1234454545 please use VoodooI2C's Gitter channel for general setup and help. I am going to close this ticket as the original problem has been addressed.

So , you mean that my touchpad is correctly configured for interrupt after all?

[lvs1974]

@Mateo1234454545: pin was correct, but code in DSDT probably not.
Now, in SSDT-I2C.dsl you can try another pins.
And you definitely can try polling mode, since you can easily change SSDT-I2C.dsl for polling mode: https://github.com/alexandred/VoodooI2C/blob/master/Documentation/Polling%20Mode.md
In _CRS must be Return (ConcatenateResTemplate (SBFB, SBFI)) or Return (SBFB).
BTW: I prefer polling mode since CPU usage is less than in interrupt mode.

[Mateo1234454545]

Will try.

I think I found the problem with the buggy touchpad with latest commits.
If I use @daliansky's version of 27Mar , voodooinput.kext doesn't load and my touchpad works great.
With latest commits without voodooinput touchpad is not recognised at all. With voodooinput is is recognised but is buggy as described.
So, problem is with voodooinput.kext. It needs optimisation or it is not needed at all for my touchpad.

I feel like I'm late to the party, but I've been trying to get interrupts mode working for a long time, and after all today trying, I finally got to something similar to what @Mateo1234454545 was getting
log.txt

I tried several pins and 0x0108 is the only one with this behaviour. I'm also quite sure it's the right one. Has this ever happened to any of you?

It should be fixed after merging https://github.com/alexandred/VoodooGPIO/pull/3

[marianopela]

It should be fixed after merging alexandred/VoodooGPIO#3

Yep, confirmed. Unfortunately my trackpad is still not working in interrupts mode, but at least it's simpler to debug. Thanks again

Thats strange. In documentation I found, exactly oposite information:

However you can consider polling as software-driven and interrupts as hardware-driven. Naturally, polling uses more system resources (such as CPU and RAM) so the optimal mode that VoodooI2C should run in is interrupt mode.

[marianopela]

Thats strange. In documentation I found, exactly oposite information:

They also say this

If you find that you cannot get your trackpad to work in interrupts mode or that interrupts mode leads to high CPU usage then it is likely you have a system with a buggy implementation of GPIO. In this case you will have to switch back to polling mode

That was true before optimisation for polling mode was done, and it is not true for modern CPUs. If I press one finger and keep it - I have 14-15% CPU usage, and it I press and keep two - I have 28-30% CPU usage.
In polling mode I have 7-8% CPU usage in any touchpad usage scenario, and ~1% if touchpad is idle (0.5% in interrupt mode).

[kecinzer]

Thank you for explanation. I will need to do more investigation about it. I'm using this SSDT patches - https://github.com/RehabMan/HP-ProBook-4x30s-DSDT-Patch/commit/b7b95d740092a14b65cbf7c7bc198918789ccdc3

But I assuming this changes will come in future release of VoodooI2C.

[Mateo1234454545]

For me is opposite.
Polling mode doesn't work well , cursor movement is buggy (my APIC pin is 0x33).
In Interrupts mode when press one or two fingers , cpu usage is 1-3%.

[kecinzer]

I know, that this is off topic, but there is my SSDT patches:
https://drive.google.com/open?id=1TeT5X3_3yPOWOt4vwsoE3WzdxAGtytGb

Can someone explain me, why my VoodooI2C kext working? I can see nothing related to I2C.

[kecinzer]

@Mateo1234454545 can you please tell me how you switch between polling and interrupt mode? I tried my own SSDT patch, but it seems not working.

[kprinssu]

@kecinzer please go to the VoodooI2C Gitter channel for help.

[Mateo1234454545]

Problem solved with https://github.com/alexandred/VoodooI2C/pull/287 (also problem with drag and drop and 2 finger scroling) with EnableForceTouchEmulation set to False.
