[Ubuntu-x-swat] [Bug 1990089] Re: Screen freeze when performing memory stress in Wayland mode

2023-05-15 Thread Kai-Heng Feng
I can verify the issue is fixed following the steps:
1) Enable -proposed pocket, and upgrade mesa
2) Run `stress-ng --stack 0 --mmap 0 --aggressive --timeout 300`
3) See if GNOME is frozen
4) Use top to observe CPU usage

With the new mesa, GNOME is no longer hung and there's no high CPU usage
anymore.

[Ubuntu-x-swat] [Bug 1987038] Re: Fix slow refresh rate when AMD GPU screen in reverse prime mode

2022-09-12 Thread Kai-Heng Feng
Basically the same as Jammy.

I enabled focal-proposed and upgrade xserver-xorg-video-amdgpu. Made
sure Wayland was not selected in GDM as Xorg is the default, then
connected an external monitor which routes to AMDGPU instead of Intel.
Close the lid to make the external monitor the single display, the
refresh rate is smooth so the issue is resolved.

I also boot up an AMD APU laptop to test the package and no regression
was found.

[Ubuntu-x-swat] [Bug 1987038] [NEW] Fix slow refresh rate when AMD GPU screen in reverse prime mode

2022-08-19 Thread Kai-Heng Feng
Public bug reported:

[Impact]
When AMD GPU is a GPU screen using reverse prime and its the only display, the 
fresh rate is very slow.

[Fix]
Enable present extension for GPU screen so it can be a viable CRTC to be 
selected.

[Test]
On a I+A laptop and external displays are routed to AMDGPU, disable internal 
display like closing lid can observe the issue.

With the fix applied, the external display becomes very smooth.

[Where problems could occur]
I personally don't see why GPU screen can't use present extension, but this is 
Xorg so there might be some arcane reasons I didn't think of.

2021-08-09 Thread Kai-Heng Feng
Can you please run `watch -n0 cat /proc/interrupts` and check whether
"i2c_designware" or "SYNA8009:00" number is increasing without touching
the touchpad?

[Ubuntu-x-swat] [Bug 1918855] Re: Xorg xserver got signal 6 to abort

2021-07-06 Thread Kai-Heng Feng
I enable -proposed and do a dist-upgrade, made sure
21.0.3-0ubuntu0.1~20.04.1 is installed, then reboot and run stress-ng:

$ stress-ng --stack 0 --timeout 300
stress-ng: info:  [1782] dispatching hogs: 16 stack
stress-ng: info:  [1782] successful run completed in 300.47s (5 mins, 0.47 secs)

The desktop session didn't crash so it's still alive.

I think it's another bug. The log from original bug report shows that
the system has 32G ram, so the abort() is less likely triggered by OOM.

I found that `find /sys | grep edid$ | xargs file -i` will always report
the file is empty.

Please use `find /sys | grep edid$ | xargs cat` to find out which one is
non-empty and attach the EDID here.

Yes, the EDID needs to be read from DRM drivers, then userspace will use
the EDID exported from DRM.

Do you mean long press or a short press? I think this is expected

It doesn't look like a power management issue, somehow the trackpad just
stop responding during a short usage.

Can you please boot with kernel parameter "dyndbg='file drivers/usb/*

2020-04-23 Thread Kai-Heng Feng
** Description changed:

+ === SRU Justification ===
+ [Impact]
+ PMIC_OPREGION is required to make GFX works on Bay Trail and Cherry
+ Trial based tablets.
+ 
+ [Fix]
+ Enable CONFIG_PMIC_OPREGION.
+ CONFIG_GPIO_CRYSTAL_COVE needs to be loaded before i915 to control
+ panel, so change it to builtin.
+ 
+ These configs are aligned with Fedora kernel.
+ 
+ [Test]
+ The i915 can now kinda work albeit hitting another bug. That's a
+ different issue though.
+ 
+ [Regression Potential]
+ Low. These configs only affects Intel-based budget tablets, GFX never
+ worked.
+ It's a bit late for Focal so only enable configs in Unstable.
+ 
+ === Original Bug Report ===
+

Thank you, Hans.

The difference is CONFIG_GPIO_CRYSTAL_COVE=m, so we need to make it
builtin or make it load before i915 in initramfs.

I'll build another kernel for testing.

[Ubuntu-x-swat] [Bug 1840592] Re: systemd-backlight does not save and restore brightness for nvidia display

2019-11-07 Thread Kai-Heng Feng
The backlight device only gets registered after it's opened by graphical
session.

And the backlight gets unregistered when graphical session stops, hence
when systemd-backight@.service's "Conflicts=shutdown.target" triggers,
the backlight is already gone so the brightness wasn't saved.

Since it's not saved, the backlight won't be restored for next boot.

The easiest approach is to let nvidia driver always registers the
backlight device.

[Ubuntu-x-swat] [Bug 1848741] Re: [amdgpu] Ubuntu 19.10 horizontal graphics corruption on AMD Ryzen 2500u (Raven Ridge)

2019-10-31 Thread Kai-Heng Feng
I guess this patch fixes the issue:
commit b05f65d7720b172b6fde3abfa49ed66837071d45
Author: Alex Deucher 
Date:   Thu Aug 15 08:27:09 2019 -0500

drm/amdgpu/gfx9: update pg_flags after determining if gfx off is
possible

We need to set certain power gating flags after we determine
if the firmware version is sufficient to support gfxoff.
Previously we set the pg flags in early init, but we later
we might have disabled gfxoff if the firmware versions didn't
support it.  Move adding the additional pg flags after we
determine whether or not to support gfxoff.

Fixes: 005440066f92 ("drm/amdgpu: enable gfxoff again on raven series (v2)")
