Intel HD Graphics I915 video driver (OS108 NetBSD 9.1)

wlfaws

Hello, guys from UnitedBSD

Good afternoon

All right with you?

I would like a help from you regarding the video driver below:

Device: intelfb0
Chipset: Intel i915 (DRM)
S.O Name: OS108
System base: NetBSD 9.1
Graphical environment: MATE Desktop Environment 1.24.0

Because if you use the driver "xf86-video-intel-2.99.917.20200515 Modular Xorg Intel video driver" it does not work. The only one that worked now for the configuration mode indicated by OS108's @Jay. Below is a configuration of /etc/X11/xorg.conf.

Section "Device"
Identifier "Card0"
Driver "modesetting"
Option "TearFree" "True"
Option "AccelMethod" "sna"
EndSection

NOTE: I also tried with the wsfb driver, but the performance is lower than modesetting. I have already done tests with both the configuration mode and wsfb with the "uxa" option, but also without success.

I am grateful for the help.

wlfaws Can you tell me what exactly the problem is? As far as I can see, there're no serious errors with the graphics here: Your card (a Valleyview Gen7) is supported and detected correctly, and the standard Xorg server (not the modular one) is running fine--if at a lower screen resolution.

It is not exactly an error, and loss of performance in some applications. When I used Fedora Linux I ran some applications with better performance, which is why I believe it is something related to the driver. But that is not something that prevents me from using the system. But if you hear a way to improve this performance, I would like to improve it. My hardware is not faster to use the Intel driver I believe it would work better. Below is my hardware data.

CPU: Celeron dual core "Intel (R) Celeron (R) CPU N2830 @ 2.16GHz"

Memory: 4GB of ram.

Shared ram video: 512MB

@wlfaws I've cleaned-up your posts. Please don't post dmesgand Xorg logs directly into the forum, use an external service for these.

pin Hello, Pin
good night
How are you?
Sorry I didn't know that. As soon as I saw the link https://pastebin.com I created an account afterwards.
Thanks for the tip and sorry for the inconvenience.

wlfaws It is not exactly an error, and loss of performance in some applications.

Not being a graphics guy, I'm not sure what to suggest here, except general things like:

Reduce shared mem. allocated to graphics (just use the BIOS default: usually 64 MB)
For the modesetting driver, turn ShadowFB off.
Play with the other settings. (TearFree and AccelMethod "SNA" are only for the intel driver.)
Use the intel driver--just replace modesetting with intel
Play with the Intel driver options.

rvp Thank you very much, I will make the changes.

rvp Hello, RVP
Good afternoon
How are you?
I was looking at this manual https://man.netbsd.org/NetBSD-9.1-STABLE/amd64/intel.4, and I didn't find the i915 / Valleyview gen7 Chipset. At the time, I had still talked to @Jay, because the graphical environment went up, but when it was time to log in, the lyrics were all buggy. Then he said that he could use the modesetting driver. In some internet searches last week, I saw that there were some people with this problem, but there was no solution until then. But I will continue to use the modesetting driver for now, and I will try @Jay's tips on improving the computer's performance. Gratitude to all for the help.

Jay Gratitude, I will look at this post.

wlfaws I was looking at this manual https://man.netbsd.org/NetBSD-9.1-STABLE/amd64/intel.4, and I didn't find the i915 / Valleyview gen7 Chipset.

Defined here (line 242)
Used here (lines 245,378)

Valleyview (Baytrail) cards show up as Intel(R) HD Graphics in the man-page.
Try using Option "AccelMethod" "UXA" with the intel driver.

Hello everyone,
good night
All right with you? I tried this way with these settings, but in applications that require 3D acceleration, the screen is flashing. I continued searching on the internet and found an option called "DRI" in option "3", but without success. I tried "DRI" "2", also without success. Only with the option "DRI" "1" it worked without flashing the screen, however it is slow. But I noticed that in "DRI" "3" the applications run fast, but the screen flashes and immediately afterwards they crash. In short, using the configuration below:

#Intel
Section "Device"
Identifier "intelfb0"
Driver "Intel"
Option "Accel" "True"
Option "AccelMethod" "uxa"
Option "DRI" "1"
EndSection

I have pretty much the same thing as using modesetting in the settings below:

#Modesetting
Section "Device"
Identifier "intelfb0"
Driver "modesetting"
Option "SWcursor" "False"
Option "kmsdev" "/ dev / dri / card0"
Option "ShadowFB" "True"
Option "DoubleShadow" "False"
Option "AccelMethod" "glamor"
Option "PageFlip" "True"
EndSection

NOTE: I tested other options of these drivers, but without success.

Is there anything else I can do?

I'm waiting

Thank you very much.

wlfaws But I noticed that in "DRI" "3" the applications run fast, but the screen flashes and immediately afterwards they crash.

Have you tried enabling a compositor like the wiki recommends?

rvp Hi, RVP
good night
How are you?
I'll run some tests here.
Thank you very much
