--- Comment #2 from Michel Dänzer <michel@daenzer.net> ---
The messages appear when the AMD GPU is woken up due to userspace using some
functionality of the amdgpu kernel driver.

Does

 amdgpu.runpm=0

on the kernel command line prevent the stuttering? If so, I hope somebody can
help you track down how userspace is causing the AMD GPU to wake up.

(Note that the above will keep the AMD GPU powered on all the time; it's
intended to confirm that the stuttering is related to powering up the AMD GPU,
not as a permanent solution)

Adding

amdgpu.runpm=0

helps big time but I know this means both the AMD and Intel would be running
all the time, this is not ideal. As I said before I would like to have the
Intel GPU running as my main and only activating the AMD GPU when I want to
make use of a better GPU, preferably with PRIME.

I'm not seeing stuttering, but I do see AMDGPU loading up each time I play a
video on MPV or Chromium

The last time I saw this something was using drmGetDevice rather than
drmGetDevice2

My guess they're the most likely candidates for this happening

If this is a library file issue how should I go fixing this?   Does this need a

I'm not sure, I'm hoping I might be pointing the devs in the right direction

I'm not sure if drmGetDeviceNameFromFd vs drmGetDeviceNameFromFd2 could cause
the issue too - I think it might

I found in the xserver:

hw/xfree86/dri2/dri2.c:    if (drmGetDevice(info->fd, &dev) || dev->bustype !=
DRM_BUS_PCI) {
hw/xfree86/drivers/modesetting/dri2.c:    info.deviceName =
drmGetDeviceNameFromFd(ms->fd);

drm/xf86drm.c:int drmGetDevices(drmDevicePtr devices[], int max_devices)

In the AMDGPU DDX:

src/amdgpu_dri2.c:      info->dri2.device_name =
drmGetDeviceNameFromFd(pAMDGPUEnt->fd);

And in libva:

va/drm/va_drm_utils.c:    name = drmGetDeviceNameFromFd(fd);

I notice in the old libva1 code there was no drmGetDevice stuff and it's only
in libva2 I could find the above reference

These are only called during X server startup.


> va/drm/va_drm_utils.c:    name = drmGetDeviceNameFromFd(fd);

This should only be called when a video player using VA-API runs standalone,
not via X (or Wayland), and even then only once.


Try running

 sudo perf record -e rpm:rpm_resume --call-graph=dwarf

in a terminal, then do whatever is needed to reproduce the problem, then
interrupt the perf command with Ctrl-C and attach the output of

 sudo perf report --header

Ransu, please try to get the information from your system the same way Mike
did. Looks like he's running into a different issue which only happens using
the Xorg modesetting driver.

Sorry for the lack of updates, life got in the way and then this week I made a
stupid mistake on where I was sending data with 'dd'. I didn't lose any
important data but it did force me to have to setup my laptop from scratch.

Good news! As of kernel 4.18.16 I no longer see an issue, knock on wood. I'm
going to give it a week and report back but the AMDGPU driver does not seem to
be reloading like mad anymore. 

Linux Y40-80 4.18.16-arch1-1-ARCH #1 SMP PREEMPT Sat Oct 20 22:06:45 UTC 2018
x86_64 GNU/Linux


I get the following two messages whenever I request the AMD GPU with
"PRIME_DRI=1" and only when I request the AMD GPU. When I'm not making use of
the discrete graphics and only the dedicated Intel of my laptop I do not see
the below two messages repeated over and over anymore, nor do I see any
stuttering. 

> [drm] PCIE gen 2 link speeds already enabled
> amdgpu 0000:05:00.0: PCIE GART of 1024M enabled (table at 0x000000F400000000).



One other thing I should note before I set up the system with AMDGPU by putting
the following kernel command line arguments into my grub config
"radeon.si_support=0 amdgpu.si_support=1"    radeon alone would crash my
system. I needed to go into a different TTY before login into XFCE to get
things setup following this page https://wiki.archlinux.org/index.php/AMDGPU

So now that things appear to be working I just have a few more questions.


Does this mean that the discrete GPU should be making use of power saving
features and shouldn't be draining too much power if I'm not making use of it?

and

Does my card support AMDGPU-PRO drivers? If so is there any real advantage of
using the "PRO" extras over the standard open source driver?

Oh I also did add the kernel modules as follows to my mkinitcpio configuration
in case that helped any, first three are for the two GPU my laptop has and the
rest are for the encrypted disk.

MODULES="i915 amdgpu radeon dm_mod dm_crypt ext4 aes_x86_64 sha256 sha512"

You only need the "PRO" driver if you need OpenGL that is certified for
workstation applications or OpenCL.

I'm closing this as fixed. The latest code is working for me. I have now
upgraded to kernel 4.19.2 in Arch Linux and things appear to continue to work
as expected.
