Hi Matthias,
I had vc4-kms-v3d-pi5 enabled in extraconfig (without cma parameter), but I've
updated raspberrypi-firmware(-dt) rpms from experimental repos, iommu nodes are
nowhere to be found in mainline dts anyway, added the reg property, patches
you've linked from Andrea applied to the next, compiled the kernel and overrun
dtb's and v3d works.
Really cool stuff, glmark is running fullscreen in fullhd with 233 score.
Thanks :)

Sway won't run in 4K tho, FullHD only:
DRM_IOCTL_MODE_CREATE_DUMB failed: Cannot allocate memory
00:00:01.114 [ERROR] [wlr] [render/allocator/gbm.c:118] gbm_bo_create failed:
Cannot allocate memory
00:00:01.114 [ERROR] [wlr] [render/swapchain.c:105] Failed to allocate buffer
According to kernel CMA size is 64MB and doesn't respect the cma-256 set
through extraconfig, when I set cma=256M as a kernel parametar and run sway, I
get a black screen with:
