modesetting difference between 13.2-STABLE and 14.3-RELEASE?

Hello,

Q1. Is there a drop in hardware support specifically for Intel HD Graphics for the xorg driver modesetting between 13.2-STABLE and 14.3-RELEASE?

Q2. As an alternative option - is there any chance of getting hardware acceleration to work with xorg+xf86-video-intel for old hardware?


I dual boot a 10 year old Intel Pentium N3700 Braswell laptop with Intel HD gfx with one 13.2-STABLE and one 14.3-RELEASE.

For the 13.2-STABLE i run xorg+modesetting and here the modesetting enables glamorgl so I have hardware acceleration and all is fine.

For the 14.3-RELEASE it's a different story.

1. Modesetting fails on boot with white cursor top left and mouse pointer middle on a dark screen.
Snippet from /var/log/Xorg.0.log
[ 16.038] (==) modeset(0): DPI set to (96, 96)
[ 16.038] (II) Loading sub module "fb"
[ 16.038] (II) LoadModule: "fb"
[ 16.038] (II) Module "fb" already built-in
[ 16.047] (EE)
Fatal server error:
[ 16.048] (EE) Caught signal 6 (Abort trap). Server aborting​

2a. As a second option I have also looked at xorg+xf86-video-intel and run glxgears without DRI (ie no hardware acceleration) cogwheels spin but I get many lines like below in output.

'-avx512pf' is not a recognized feature for this target (ignoring feature)
'-avx512er' is not a recognized feature for this target (ignoring feature)​

2b. If I run xorg+xf86-video-intel but with DRI set to 3 glxgears SIGABRTs.

glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
fish: Job 1, 'glxgears' terminated by signal SIGABRT (Abort)​

Is there a reason for using the legacy x11-drivers/xf86-video-intel instead of graphics/drm-61-kmod?

Hi Beastie, thanks for replying :)

I came by way of drm-61-kmod - startx gives dark screen with white cursor up left and mousepointer.

Snippet from Xorg.0.log for drm-61-kmod:

[ 18.554] (==) modeset(0): DPI set to (96, 96)
[ 18.554] (II) Loading sub module "fb"
[ 18.554] (II) LoadModule: "fb"

[ 18.555] (II) UnloadModule: "scfb"
[ 18.555] (II) Unloading scfb
[ 18.555] (II) UnloadModule: "vesa"
[ 18.555] (II) Unloading vesa
[ 18.565] (EE)
Fatal server error:
[ 18.565] (EE) Caught signal 6 (Abort trap). Server aborting
​

After drm-61-kmod I tried drm-515-kmod with exactly same result as for drm-61-kmod.

[ 15.783] (==) modeset(0): DPI set to (96, 96)

[ 15.783] (II) Unloading scfb
[ 15.784] (II) UnloadModule: "vesa"
[ 15.784] (II) Unloading vesa
[ 15.792] (EE)

Note that graphics/drm-kmod pulls in graphics/drm-510-kmod on 13.2 and graphics/drm-61-kmod on 14.3.

First of all a sidenote - Thank you again SirDice for keeping fs-uae alive in the ports tree. And also I think you did the same for Mame at some point - thank you for that also!


Following SirDice hint leads to this thread https://forums.freebsd.org/threads/how-to-tell-which-xorg-video-driver-is-in-use.85014/

And these commands for FreeBSD 14.3:

pkg install drm_info

drm_info | grep "Driver\|Device"
drmModeGetPropertyBlob: No such file or directory
drmModeGetPropertyBlob: No such file or directory
drmModeGetPropertyBlob: No such file or directory
drmModeGetPropertyBlob: No such file or directory
drmModeGetPropertyBlob: No such file or directory
├───Driver: i915 (Intel Graphics) version 1.6.0 (20201103)
├───Device: PCI 8086:22b1 Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller


And here's the output from drm_info for FreeBSD 13.2

drm_info | grep "Driver\|Device"
├───Driver: i915 (Intel Graphics) version 1.6.0 (20200917)
├───Device: PCI 8086:22b1 Intel Corporation Atom/Celeron/Pentium Processor x5-E8000/J3xxx/N3xxx Integrated Graphics Controller


It looks like the driver i915 (Intel Graphics) version 1.6.0 (20201103) is missing drmModeGetPropertyBlob:?

Thanks. Need to update it though. But things changed with the latest version and I may need to redo the entire port from scratch. Haven't had the time for that yet.

Are there any .conf file in /etc/X11 or /usr/local/etc/X11/xorg.conf.d/?

If yes, have you tried running Xorg without it?

Yes - I posted the output in #4 above. Xorg defaults to modesetting driver and the dark screen with cursor and pointer is visible while the Xorg.0.log file shows signal 6 abort trap.
