Fedora 40 and Helios64 => success

by Dan Horák

Hi all, after couple years of sitting under the desk I have thought it's time to try Fedora on Helios64. There was progress in mainline kernel regarding the hardware support in the past year or two, so why not to give it a try. There is no mainline u-boot support for Helios64, thus the idea was to use Armbian's u-boot, which should support EFI boot, combined with Fedora minimal disk image. After some head scratching and resolving 2 issues I got the login prompt. First issue is that Armbian's u-boot is bigger than 1 MB, thus our disk layout, where the first partition (EFI) starts at 9 MB, means it gets overwritten a bit. Solution was to shift all partitions 1 MB further. Perhaps we should default to the 10 MB in the official images too. Second issue was a crash quite late in the boot in cpu_idle() for CPU #5, which seems to be the low-power core. Workaround was to limit the number of cpus to 4 using kernel's maxcpus= parameter. The result is [dan@helios64 ~]$ sudo dmesg | head [ 0.000000] Booting Linux on physical CPU 0x0000000000 [0x410fd034] [ 0.000000] Linux version 6.8.5-301.fc40.aarch64 (mockbuild@5efd934e27f44ed09084502b9de5d773) (gcc (GCC) 14.0.1 20240328 (Red Hat 14.0.1-0), GNU ld version 2.41-34.fc40) #1 SMP PREEMPT_DYNAMIC Thu Apr 11 20:30:05 UTC 2024 [ 0.000000] KASLR disabled due to lack of seed [ 0.000000] Machine model: Helios64 [ 0.000000] efi: EFI v2.9 by Das U-Boot [ 0.000000] efi: RTPROP=0xf4ece040 SMBIOS=0xf4ecd000 MOKvar=0xf4da0000 MEMRESERVE=0xf4d97040 [ 0.000000] NUMA: No NUMA configuration found [ 0.000000] NUMA: Faking a node at [mem 0x0000000000200000-0x00000000f7ffffff] [ 0.000000] NUMA: NODE_DATA [mem 0xf755c2c0-0xf7572fff] [ 0.000000] Zone ranges: With regards, Dan

RPi Kernel memory leak leads to OOM killer running on idle system.

by Barry Scott

A number of us are seeing a reproducible kernel memory leak on RPi. There is a bug https://bugzilla.redhat.com/show_bug.cgi?id=2279327 and a thread in discuss about it with additional details: https://discussion.fedoraproject.org/t/high-memory-usage-in-f40-on-rpi-4-... Kernel 6.5.6 does not have a leak, but current kernels do. Anyone know if this is being looked at? Barry
