Virtual console devices
Hello, I am trying to optimize boot up time for my board. I ran bootchart and observed that virtual console devices are being created in very high number which finally cause the boot up time to increase by 1.5 seconds. I have been researching as to where these are actually being created and have failed to find anything concrete.Is there some way to reduce the count of virtual devices on the kernel side?

Try with gcc 4 you may get it from AUR Em dom, 5 de ago de 2018 23:07, He Huanyu escreveu: > As you know,4.x version is so complex.

Re: Problem of compiling linux2.6.11.12 kernel
As you know,4.x version is so complex. And it‘s difficult to read the source code for newbies like me. Of course one of the most important reasons is that I am reading 《UNDERSTANDING THE LINUX KERNEL》 :) And it’s for 2.6.11 version. I am thinking about build a environment to practice.

Why are you trying to build 2.6.11 if you have 4.16 available? That dates to June 2005, and is only of interest to software archaeologists. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Problem of compiling linux2.6.11.12 kernel
Hi everyone, I try to compile linux kernel of 2.6.11.12 version on my 64bit archlinux. Below is my system information: linux 4.16.9-1-ARCH gcc (GCC) 8.1.1 20180531 GNU ld (GNU Binutils) 2.30 And I get a problem like this, don't know if it is because of the version of gcc or ld: /usr/bin/ld: arch/x86_64/ia32/vsyscall-sysenter.so: Not enough room for program headers, try linking with -N /usr/bin/ld: final link failed: Bad value collect2: error: ld returned 1 exit status make[1]: *** [arch/x86_64/ia32/Makefile:28: arch/x86_64/ia32/vsyscall-sysenter.so] Error 1 make: *** [Makefile:742: arch/x86_64/ia32] Error 2 I've tried to add ld parameter, but didn't know how and where to add this... Have you met this before? And how can I fix it? ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
