Thanks, that's fantastic. I've mostly reproduced your work, and have my build of your 5.0 kernel running on an XO-1.75 with an adjusted Fedora 18 user space and a fixed root= argument. > The kernel: > > git pull https://github.com/hackerspace/olpc-xo175-linux/ olpc-5.0 > > Based on vanilla v5.0.8, a few parts taken from olpc-4.8, > olpc-3.0-arm, along with my defconfig and a couple of changes to > support cross-build on Fedora 30.

Pushed as http://dev.laptop.org/git/olpc-kernel/log/?h=olpc-5.0 My dmesg; http://dev.laptop.org/~quozl/z/1hHiN5.txt I used an Ubuntu 18.04 cross-build to make the kernel I'm using at the moment, as our production builder is Fedora 18. I've started to iterate on a Fedora 30 builder, but I'm not sure I've got everything I need. Here's the packages I'm adding; gcc-arm-linux-gnu binutils-arm-linux-gnu rpm-build bison flex m4 make openssl-devel perl > Firmware: > > git pull https://github.com/lkundrak/openfirmware/ lr/olpc-xo175-3 > > A couple more small fixups here and there since lr/olpc-xo175-2.

Pushed as https://github.com/quozl/openfirmware/commits/lr/olpc-xo175-3 Released q4e00ja.rom from this as is; http://dev.laptop.org/~quozl/q4e00ja.rom Removed the dtcompat.fth fload and released q4e01ja.rom; http://dev.laptop.org/~quozl/q4e01ja.rom As the firmware will update on a standard system before the kernel will boot, this seems an okay way to do it.

Thanks, yes, it does work, though I had to recreate the xorg.conf.d symlink, not sure why. Pushed as http://dev.laptop.org/git/projects/olpc-utils/log/?h=v5.1 Packaged as http://dev.laptop.org/~quozl/olpc-utils-5.1.0-0.olpc.armv7hl.rpm http://dev.laptop.org/~quozl/olpc-utils-5.1.0-0.olpc.src.rpm > The patched packages are here: http://v3.sk/~lkundrak/olpc/ > The dracut-modules-olpc package needs to be installed prior to the > kernel. Oops, I should have read all this way before acting. I got caught up in code review. Sorry. I'll do another test using your binaries. By the way, there's an interesting symptom on WiFi, a variable latency on inbound ssh, also shows up as a latency staircase effect in outbound "ping -n -i 0.200". Also, power is not turned off on system halt. I remember fixing that once, so no biggie. -- James Cameron http://quozl.netrek.org/ _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
