Greetings,
I've got an RPi3 and am using Michael Stapelberg's preview image [0]. Thanks Michael!
I've looked at the source for building the image and am uncertain of the bootloader. With arm64 architectures, how does one determine the bootloader?
The preview image works well - until I try anything with X. I'm getting errors in the journal, such as:
kernel: [drm:vc4_bo_create [vc4]] *ERROR* Failed to allocate from CMA:
Has anyone else encountered such errors?
I've read about enabling CMA on the kernel command line, but I'd imagine I need to do that through the bootloader. The firmware directory has a subset of what the kernel boots with:
root@rpi3:~# cat /boot/firmware/cmdline.txt
console=tty0 console=ttyS1,115200 root=/dev/mmcblk0p2 rw elevator=deadline fsck.repair=yes net.ifnames=0 rootwait
root@rpi3:~# cat /proc/cmdline
bcm2708_fb.fbwidth=640 bcm2708_fb.fbheight=480 bcm2708_fb.fbswap=1 dma.dmachans=0x7f35 bcm2709.boardrev=0xa02082 bcm2709.serial=0x4e06e63d bcm2709.uart_clock=48000000 smsc95xx.macaddr=B8:27:EB:06:E6:3D vc_mem.mem_base=0x3ec00000 vc_mem.mem_size=0x40000000 console=tty0 console=ttyS1,115200 root=/dev/mmcblk0p2 rw elevator=deadline fsck.repair=yes net.ifnames=0 rootwait
Thanks for any help or hints!
Cheers,
