[parisc-linux] ttyS00 reported twice
Wed, 31 May 2000 16:41:02 +0100
There was some discussion on irc yesterday about bootup messages reporting
Found serial #0 at 0xf0823000, IRQ 538
ttyS00 at iomem 0xf0823800 (irq = 538) is a 16550A
Found serial #1 at 0xf0822000, IRQ 537
ttyS00 at iomem 0xf0822800 (irq = 537) is a 16550A
i.e. both ports reported as ttyS00. This seems to be a consequence of us
calling register_serial() before rs_init() is called. In addition there
is a chunk of initialisation in rs_init() that is #ifndef CONFIG_GSC;
that would need to be enabled so that rs_table.line is initialised,
before we would report ttyS01.
The solution might be to make register_serial() aware of whether rs_init()
has yet been called. If it hasn't, register_serial() just queues the
struct_serial that was passed in and returns success. At the end of
rs_init() we call register_serial() again for each item in the queue.
This is similar to what happens with the net devices.
