For uart serial drivers it -is the port lock. Other types of console drivers (network, -graphics, USB) will need something as well. - -Provide 2 new mandatory nbcon console callbacks (driver_enter and -driver_exit) to allow the consoles drivers to implement the -appropriate synchronization. The callbacks are also expected to -disable/enable migration. - -Signed-off-by: John Ogness <john.ogness@linutronix.de> -Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> ---- - include/linux/console.h | 4 ++++ - 1 file changed, 4 insertions(+) - ---- a/include/linux/console.h -+++ b/include/linux/console.h -@@ -296,6 +296,8 @@ struct nbcon_write_context { - * @node: hlist node for the console list - * - * @write_atomic: Write callback for atomic context -+ * @driver_enter: Callback to begin synchronization with driver code -+ * @driver_exit: Callback to finish synchronization with driver code - * @nbcon_state: State for nbcon consoles - * @nbcon_seq: Sequence number of the next record for nbcon to print - * @pbufs: Pointer to nbcon private buffer -@@ -323,6 +325,8 @@ struct console { - /* nbcon console specific members */ - bool (*write_atomic)(struct console *con, - struct nbcon_write_context *wctxt); -+ void (*driver_enter)(struct console *con, unsigned long *flags); -+ void (*driver_exit)(struct console *con, unsigned long flags); - atomic_t __private nbcon_state; - atomic_long_t __private nbcon_seq; - struct printk_buffers *pbufs; |
