When we configure the litmus-rt kernel first time, we can change the size of the buffer under the 'menuconfig'. The default number is 9, and the max valid number is 13. So my question is, is there any possible to increace this buffer size more than 13 for a redundancy reason, or that maximun number is hardware releated?

You can adjust the maximum permitted value in the file litmus/Kconfig.
