Software collection rh-php73 amv7

Hello, Over the past time received an increasing amount of request for the rh-php73 Software Collection on armv7. Mainly to be able to run nextcloud but also zabbix 5.0 requires php7x. For full disclosure: the request come from the Nethserver community, which provides a all-in-one smb server based on CentOS x86_64. And the arm port of this is a small scale community effort. This being out of the way, I have rebuild the bare minimum rh-hph73 packages to install nextcloud without issues.(1) Just pushed the source packages through mock to rebuild them for armv7, first tests are encouraging. So far so good, problem is my build system is me and my keyboard. Which is not a very sustainable way to maintain rh-php73 for armv7. See a lot of nice hardware posted to the list, to be frank a bit above the budget I'm willing to put in this community effort. Are there other people on this list who want to join the effort to provide an unofficial community driven armv7 port of rh-hph7x? Or is this even on the white-board at the CentOS altarch sig? Until now did not find a public build-system for armv7 el7 does this exist? Any suggestions are welcome. 1) development repository with first results: __Note__ this is development do not use it in a real life application! https://vps01.havak.nl/nethserver/7/devel/

Hi, Most unfortunately, my MP30-AR1 board seems to have expired today. It gets stuck in an infinite boot loop: Boot from SPI-NOR American Megatrends Boot firmware (Project MP30-AR1, BIOS Ver F01; built at 15:11:23 on Sep 5 2016) Slimpro FW Ver: 2.4 iPP Ver: 01.15.01.00 Checkpoint 2D Checkpoint 2D Checkpoint 2D Checkpoint 2D So I'm looking for a replacement. Unfortunately, everything I can get in *TX form factor seems to be nowhere nearly as good, despite 6-7 years of advancement, and I can't seem to find a replacement MP30-AR1 board listed anywhere. I am aware of these: https://www.chip1stop.com/USA/en/product/detail?partId=SOCI-0000003&mpn=SC0… Pros: - Can just buy one Cons: - Poor performance despite lots of cores, especially single-thread performance compared to the old MP30-AR1 - Only half the RAM capacity at 64GB https://e.huawei.com/en/products/servers/kunpeng/kunpeng-desktop-board Pros: - Might have half decent single thread performance matching or exceeding the old MP30-AR1 Cons: - Questionable availability, unknown pricing - Only half the RAM capacity at 64GB Is there another offering that I'm missing? I know Gigabyte do a server system, but I need something reasonably quiet and compact rather than something rack mounted making data centre grade noise. Any suggestions gratefully received. Gordan

Did run your test build (5.4.84-v8.1.el7.armhfp) from buildlogs it solved the issue and just saw (as in now) a build of 5.4.88-v8.1.el7.armhfp, wil test that one too > > >>>>> 1) https://github.com/raspberrypi/linux/commit/1bef5f25a69234613b92a0e2456870f… > > >>>>> > > >>>>> > > >>>> Pablo. > > >>>> > > >>>> _______________________________________________ > > >>>> Arm-dev mailing list > > >>>> Arm-dev(a)centos.org > > >>>> https://lists.centos.org/mailman/listinfo/arm-dev > > Pablo. > > >
