Since the dmesg buffer exists in kernel space, a kernel build is |
| 16 |
required to change its size. If recollection serves, the setting is |
| 17 |
named CONFIG_LOG_BUF_SHIFT and the value is a power of 2. For example |
| 18 |
|
| 19 |
CONFIG_LOG_BUF_SHIFT=18 |
| 20 |
|
| 21 |
sets the buffer size to 262144 bytes. |
