I’m writing some code with printk [i’m printing while in kernel mode] ,
but because dmesg is too small I’m losing the first few printk’s.
How can I increase the size of dmesg ?
thanks in advance for the help!
You need to set
CONFIG_LOG_BUF_SHIFTduring compile time. The size of the buffer can not be modified in run time.The size of the buffer is
2^CONFIG_LOG_BUF_SHIFTbytes
