Hi all, Short status update regarding this series.
Currently I am debugging booting NetBSD 9.0-RC2, which is recently released [1] The problem is that, apparently, RC2 can't mount the rootfs properly: [ 3.1871510] vfs_mountroot: can't open root device [ 3.2141370] cannot mount root, error = 6 This only happens using the RC2 filesystem image. However, the RC2 kernel can properly load & boot the RC1 filesystem image, and the RC1 kernel gives the same error on the RC2 filesystem. But I dont think its a NetBSD-RC2 issue, because on a real Orange Pi PC hardware board, this problem does not show. I'm comparing traces and adding more low-level debug output to NetBSD and QEMU to find the issue. Also I processed the review remarks which were send so far. Kind regards, Niek [1] https://www.netbsd.org/releases/formal-9/NetBSD-9.0.html On Sun, Jan 19, 2020 at 1:51 AM Niek Linnenbank <nieklinnenb...@gmail.com> wrote: > Dear QEMU developers, > > Hereby I would like to contribute the following set of patches to QEMU > which add support for the Allwinner H3 System on Chip and the > Orange Pi PC machine.
