Bug Description

=== SRU Justifications ===

[Impact]
Touchpad freezes after a brief usage.

[Fix]
Quote from the commit log:
"The stale cached value written at the final stage undoes the masking.
Fix this by re-reading the register before clearing the interrupt.

I also spotted that the interrupt-clearing code can race against
amd_gpio_irq_mask() / amd_gpio_irq_unmask(), so add locking there.
Presumably this race was leading to the loss of interrupts."

[Test Case]
Touchpad no longer freezes on ideapad 320-15ABR, a new Dell Latitude and
a new Dell Inspiron.

[Regression Potential]
Low. It limits to AMD laptops

=== Original Bug Report ===

I have installed ubuntu bionic on a Lenovo ideapad 320. The touchpad stops working a few seconds after I log in.

Leo,

Can you try kernel in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1727544/comments/35?

I cherry-picked a fix for pinctrl-amd.
If this patch alone works, I'll ask stable kernel guys to include the patch for pinctrl-amd.

Thanks kaihengfeng, the mouse is already working after a couple of minutes. I haven't been this far :)
I'll let you know if it stops working later.

Kai-Heng Feng (kaihengfeng) wrote :

Leo,
If you hysterically move multiple fingers on the touchpad for a while, does the touchpad still work?

Hey, so I upgrade the machine by mistake, and now the touchpad dies again after a few seconds/minutes. I tried reinstalling the debs you linked, but this time it doesn't seem to fix it :(

Kai-Heng Feng (kaihengfeng) wrote :

I'd try cold boot instead of warm boot.

The next artful kernel will have this fix.

In the mean time, can you try mainline kernel?

Leo Arias (elopio) wrote :

On cold boot, the touchpad dies too. I'm on bionic, is the fix going to be released here too?

About the mainline kernel, do you mean this one? http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc2/

Kai-Heng Feng (kaihengfeng) wrote :

commit 6afb10267c1692ada3a2903e31ea339917ad3ac0, is in mainline v4.14+.

It should be fixed once Bionic switches to v4.14 based kernel.

Leo Arias (elopio) wrote :

Alright! I installed v4.14.3, and it seems to work now :)
Fwiw, I tried going crazy with multiple fingers in the touchpad, and it still works.

Thank you! :)

so what does this fix-committed mean, i can download latest daily build of 18.04 and the touchpad will work?
how about 17.04 (i prefer lts but 18.04 is not quite ready right?

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-artful' to 'verification-done-artful'. If the problem still exists, change the tag 'verification-needed-artful' to 'verification-failed-artful'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
