Fedora 25 kernel source
 

Hello,

I'm using Centos 7.2.1511
Under this distribution, is it possible to download the kernel source of Fedora 25 and inspect the default .config ?

Only with this distribution 2 HSUARTs are detected. With vanilla 4.9.23 (April 2017) those UARTS are not detected:

ttyS4 at MMIO ... is a 16550A
ttyS5 at MMIO ... is a 16550A

I wonder what changes were done in the kernel source or is it only configuration.

Thank you,
Zvika

CentOS 7.2.1511 : When / if you can update (# yum update), you will have the latest = 7.3.1611 : $ cat /etc/redhat-release

You can download any package from any other 'Linux OS' / any package version, if you have a link.

Hello,

Thank you for your reply !

Under live fedora I ran: "yum install kernel-devel"

Will this download the kernel source used to compile the running kernel ?

Thank you,

Re #3.
No. 'kernel-devel' is not the complete source.
'kernel-devel' is the headers required to compile a third party kernel module.
(Or e.g. a hello.ko module.)

If you have a liveCD of Fedora, simply look at /boot for the config file(s). Text file, just run grep or maybe diff against the CentOS .config
New functionality is added to the kernel constantly - Fedora is closer to the head of this change cycle. Less likely that it is patched by the Fedora devs.
