Tiny Core Base > piCore Test Releases
piCore15.0 Beta
Juanito:
Thanks for the suggestion.
There are a couple of scripts, which produce:
--- Code: ---Section "OutputClass"
Identifier "vc4"
MatchDriver "vc4"
Driver "modesetting"
Option "PrimaryGPU" "true"
EndSection
--- End code ---
..but the xorg log says "Option "PrimaryGPU" is not used"
and one that says "Glamor should not run on platforms prior to Pi 4":
--- Code: ---Section "Device"
Identifier "kms"
Driver "modesetting"
Option "AccelMethod" "msdri3"
Option "UseGammaLUT" "off"
EndSection
--- End code ---
..but as per the xorg log, glamor is not disabled by it.
If I delete libglamoregl.so, it doesn't help :(

not sure, can it be connected with `disable_fw_kms_setup`? In my case with v4+LCD+Xorg there's
--- Code: ---display_auto_detect=1
dtoverlay=vc4-fkms-v3d
disable_fw_kms_setup=1
--- End code ---
in config.txt and I've not touched Xorg.conf at all
Juanito:
dtoverlay=vc4-fkms-v3d is depreciated, what happens if you use dtoverlay=vc4-kms-v3d?

I've not known that, it has been always working there, so I've not thought to change it.
wiil test a bit further with vc4-kms-v3d and let it know...
p.s. meantime just for test checked it out with hdmi monitor, with hdmi it also works

with vc4-kms-v3d it doesn't work in my case, looking at Xorg.log there's difference with fkms:
--- Code: ------ fkms
+++ kms
-(II) xfree86: Adding drm device (/dev/dri/card0)
-(II) Platform probe for /sys/devices/platform/soc/soc:gpu/drm/card0
-(**) OutputClass "vc4" setting /dev/dri/card0 as PrimaryGPU
+(II) no primary bus or device found
...
--- End code ---
despite that I can see /dev/dri/card1 there, no idea why it comes in card1 slot with kms, maybe some kindof race condition (I've not digged into it)
