Grub not updating boot configs
by Mike Calderwood 27 Jun '17

27 Jun '17

Hey guys. This is probably going to be a really dumb question, but a) I only have limited familiarity with Grub2 and b) I really don't want to have to rebuild my SD card image from scratch...again. I have a Pine64 running 7.3.1611 aarch64, and it started out on kernel 3.10.101. I've issued yum update after yum update, and it finally dawned on me that it wasn't ever booting into the new kernels I was installing. I have 5 of the 4.x kernels installed, but it's never even attempted to boot into them. I've dug around a little bit, and here's what I can see so far: 1) By RPM list, I don't even have a 3.x kernel installed anywhere. It was installed during the initial system image in some way outside of RPM/yum, and it hasn't been removed in the time since. 2) I don't have a grub2.cfg file like my x86_64 systems have. I have a symlink at /etc/grub2-efi.cfg that is supposed to point to ../boot/efi/EFI/centos/grub.cfg, but that doesn't exist either. 3) If I run grub2-mkconfig, I can get a seemingly-valid grub2.cfg file that only references the 4.x kernels I have installed. I put that file at the symlink target from #2 and rebooted, but it apparently had zero impact. It rebooted just fine...into 3.10.101. So my question boils down to this: what exactly am I missing here that's preventing this from updating kernels correctly? Thanks for the help. Mike

This will also enable mpt3sas driver to support these chipsets. This patch was partially backport for Centos 7.3 to enable those pciids and we don't need other code. (Ref: b130b0d mpt3sas: Added support for high port count HBA variants) + 1039-misc-fix-pca955x-pm80xx-mpt3sas.patch This is a roll up of the following upstreamed patch for adding miscellaneous fix for pca955x, pm80xx, mpt3sas. aace34c leds: pca955x: Correct I2C Functionality. e83596b pm80xx: Remove bogus address masking in pm8001_ioremap(). 83c3d34 mpt3sas: Fix panic when aer correct error occurred.

Thanks for the new armv7hl kernel
by Robert Moskowitz 18 Jun '17

18 Jun '17

Anything to note about the new kernelll? Trivial question, why is it 4.9.30-203 and not 4.9.30-204, replacing 4.9.13-203? Also how do people claim to have the linux box up for 6 mo or more when kernel updates come out more frequently than that? Not that I mind having to install a new kernel... thanks Bob

CONFIG_HZ for arm64
by Phong Vo 14 Jun '17

14 Jun '17

Hi Jim and all, I notice that CONFIG_HZ_1000=y in config-generic, and CONFIG_HZ=100 in config-generic. This will result in a final .config for arm64 with CONFIG_HZ_1000=y CONFIG_HZ=1000 instead of 100 as intended. config-arm64 needs to be changed to specify CONFIG_HZ_100=y instead of CONFIG_HZ=100, so the final dotconfig will be CONFIG_HZ_100=y CONFIG_HZ=100 Please comment. -Phong

Missing xhci-platform.ko in initramfs
by Phong Vo 08 Jun '17

08 Jun '17

Hi Jim, We are working on our next-gen SATA IP and it no longer requires xhci-xgene driver but instead would work with just the standard ahci-platform driver. On testing this, we just realize that ahci-platform.ko is present in CentOS installer initrd, but on installation completion, it is missing from initramfs. We would appreciate if you can take care of this for the next build. -Phong
