As with 14.1.1, this version is OK with the latest Linux kernels (tested with 14.6.10 and 14.7-rc6). Robert Gadsdon.   May 22, … Continue reading →

GCC – Update to 8.1.1 – Still Gives Kernel Compile Warnings..

Adventures With Linux ™ Posted on May 7, 2018 by RGMay 7, 2018

Fedora 28 has GCC 8.1.1 available (currently in ‘updates-testing‘ repo), and I tested this with Kernel 4.17-rc4, to see if there was any improvement in the horde of warnings generated with 8.0.1. In short, there is no real difference: ……………………………… CC security/keys/request_key.o arch/x86/kvm/lapic.o: warning: objtool: kvm_lapic_reg_read()+0x126: sibling call from callable instruction with modified stack frame arch/x86/kvm/lapic.o: warning: … Continue reading →

Adventures With Linux ™ Posted on May 2, 2018 by RGMay 2, 2018

Fedora 28 has been released, but this includes GCC 8 (8.0.1) which – currently – is not capable of compiling Kernel 4.16 as-is (tested with 4.16.6): …………………………….
