[Kernel-packages] [Bug 1878432] Re: rpi3a+ does not boot with core20

@ plars How come you manage to use Bionic classic, Focal classic, UC18 on that Pi 3A+ without adjusting config.txt and believe that this is a UC20 regression? Given that my understanding is that 3A+ needs that manual adjustment on all our other targets. ** Changed in: linux-raspi (Ubuntu)

dtoverlay=vc4-fkms-v3d,cma-256 Telling the kernel to allocate/reserve 256MB of contiguous memory for DMA operations is not a sensible thing to do on a device that only has 512MB of memory available. ** Changed in: linux-raspi (Ubuntu Focal) Status: New => Invalid -- You received this bug

[Kernel-packages] [Bug 1878432] Re: rpi3a+ does not boot with core20

I hadn't realized it at first, but this is actually similar to something we've seen in the past. There's some contiguous memory that is allocated and locked if vc4-fkms-v3d is enabled in the config.txt. This is ok for platforms with more RAM, but the RPI3A+ is too constrained. Removing that line wi

Note that I reproduced this in an amd64 VM with today's beta snaps booted with -m 512 MB, so I think this is just that uc20 currently requires more than 512 MB of RAM to boot at all... -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-
