Bug ID: 119631
Summary: RadeonSI get a huge performance dip with used with the
nine state tracker
Product: Drivers
Version: 2.5
Kernel Version: 4.7-rc1
Hardware: x86-64
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: b747xx@gmail.com
Regression: No
Hi,
I have a Radeon 7970HD and I use the Gallium Nine state tracker to play a
specific game (EVE-Online). I did notice that the performance take a big dip
when used with the kernel 4.7-next and -rc1. I did know about a regretion
affecting some opengl game, that might and might not be related.
Using the kernel 4.7, I lose about 1/3 to 2/3 of the fps depending of the
situation.

Compared to 4.6? Can you bisect?

Compared to 4.6-rc5
There.
c63dd758589b1f7e8398841d1f443f06ebfbcefc is the first bad commit
commit c63dd758589b1f7e8398841d1f443f06ebfbcefc
Author: Michel Dänzer <michel.daenzer@amd.com>
Date: Fri Apr 1 18:51:34 2016 +0900
drm/radeon: Support DRM_MODE_PAGE_FLIP_ASYNC
When this flag is set, we program the hardware to execute the flip
during horizontal blank (i.e. for the next scanline) instead of during
vertical blank (i.e. for the next frame).
Currently this is only supported on ASICs which have a page flip
completion interrupt (>= R600), and only if the use_pflipirq parameter
has value 2 (the default).

Does setting the environment variable thread_submit=true for the EVE-Online
process avoid the problem?

No,thread_submit=true just remove more fps.
Big drop if I run EVE without DRM_MODE_PAGE_FLIP_ASYNC

Hi,
It looks like to be a bug in gallium nine, wine side. (Though I don't get why
thread_submit=true didn't help)
Please try with the following diff:

I will test the patch this night.
Isn't thread_submit just to fix rendering on DRI PRIME or something like that?

--- Comment #12 from Axel Davy <vebveb@hotmail.fr> ---
thread_submit delays submission of buffers to the X server until the moment the
buffer has all rendering finished.
This is useful for DRI PRIME, because the kernel doesn't have yet all the
pieces to have the other card wait for the rendering.
I thought perhaps in your case the issue was that the async flip was taking too
long because it needed to wait for the rendering to finish, but apparently not.

Tested Axel patch.
It making it better. Instead of loosing about half of the fps, I lose about 10
337 -> 331
175 -> 165
But still have a "small" loss, I don't know if it's normal with
DRM_MODE_PAGE_FLIP_ASYNC or no. Note, I did test the patch with
DRM_MODE_PAGE_FLIP_ASYNC disabled too and did get the same exact fps than
without the patch.

The DRM_MODE_PAGE_FLIP_ASYNC change can't have any effect with Axel's patch,
because it explicitly forces the Present operations to be executed as copies
instead of flips. The difference you're seeing must therefore be caused by
something else.

What's the status of this issue? Just wondering, as this issue is listed
in my regression reports for 4.7 and it seems nothing much happened for
more than a week now – which is a bad sign as the 4.7 release seems only
a week or two away.

This isn't a kernel regression. It's a Wine/nine issue.

Looks like it may actually have been a kernel regression.
