Kconfig set default macro bug?

Hi all, I'm just playing with the early printk macros of the low level printk. The address of the UART port is set to a default value [1]. So if you save the config and then enter again in menuconfig, you are not able to change the value to a different default value (I suppose because Kconfig see

Re: What is the benefit of running CONFIG_SMP on single core device?

I am running an ARM cpu and linux kernel during kernel init on SMP enabled (running with single core in DT) sends SGI to itself while SMP disabled does not. Am puzzled why it does that? AFAIK there is no hyper threading on ARM On Wed, Apr 9, 2014 at 4:51 PM, Kristofer Hallin wrote: > Using SMP w

Re: What is the benefit of running CONFIG_SMP on single core device?

Using SMP would let your system take advantage of HyperThreading. If you have a fairly decent CPU there is a good chance that your single core have support for HyperThreading which will improve parallelization. On Wed, Apr 9, 2014 at 1:05 PM, Mj Embd wrote: > -- > -mj > >

Cannot use USB device after compiling new kernel.

I am using 3.14.0 kernel version. I compiled using localmodconfig. I am using Ubuntu in my Lenovo U410 Ultrabook. I can use USB mouse, keyboard, pendrives with the distro kernel 3.11.0-18-generic. I can use USB mouse in distro kernel, but cannot use the same in compiled kernel. I can plug in new
