Source: linux Version: 5.9.11-1 Severity: wishlist Dear Maintainer, From 5.10, Linux vc4 driver starts supporting Raspberry Pi GPU as https://www.phoronix.com/scan.php?page=news_item&px=RPi4-Display-Linux-5.10-Coming From Ubuntu kernel experience, CONFIG_DRM_V3D seems necessary to fully use its hardware acceleration, as https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1850876 Could you consider to enable CONFIG_DRM_V3D for arm64 and possibly for armhf?

Control: tags -1 + patch
Just adding CONFIG_DRM_V3D=m is not enough,
as reported at
https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1876862/comments/5
The following patch seems necessary, which has been introduced in
the Ubuntu kernel.
change
linux/drivers/gpu/drm/v3d/kconfig
- depends on ARCH_BCM || ARCH_BCMSTB || COMPILE_TEST
+ depends on ARCH_BCM || ARCH_BCMSTB || ARCH_BCM2835 || COMPILE_TEST
Best regards, Ryutaroh Matsumoto

Control: retitle 968181 GPU/DRM acceleration unavailable on Raspberry Pi I modprobe'ed v3d.ko on vanilla Linux kernel 5.10.1, but /dev/dri/render* does not appear like https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/1880125/comments/14 https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1850876/comments/33 Simply compiling and loading v3d do not seem to enable DRM/GPU acceleration on RPi4... We may need some work for enabling GPU acceleration on Raspberry Pi series... Ryutaroh
