PowerMac serial console confusion
Hi,
On Apple Xserve G5, the device tree looks like this with Linux v3.12:
/proc/device-tree/ht@0,f200/pci@3/mac-io@7/escc@13000/ch-b@13000
/proc/device-tree/ht@0,f200/pci@3/mac-io@7/escc@13000/ch-a@13020
Linux picks the ch-a as the first serial port:
[2.288585] 0.00013020:ch-a: ttyS0 at MMIO 0x80013020 [...]
Also in Open Firmware the primary serial port seems to be ch-a (there
is only one port in the box anyway). However, that won't work in GRUB
and I need to say "serial escc-ch-b --speed=57600" to get the serial
console working.
It would seem that GRUB 2.00 has ch-a and ch-b the other way round:
add_device (macio_addr[2] + escc_addr[0] + 32, 1);
add_device (macio_addr[2] + escc_addr[0], 0);
[...]
add_device (grub_addr_t addr, int channel)
[...]
port->name = grub_xasprintf ("escc-ch-%c", channel + 'a');
Is this a bug or maybe I have missed something?
A.

2 quick questions
Is it possible to pass a command to a Linux based OS? So for instance I select Ubuntu or Fedora and I tell it to run some script as soon as it boots and I can put this comand in the menuentry. My second question is that is it possible to control navigation within GRUB using a joystick? I know it's possible to treat a joystick as a keyboard in several OSes, but at the boot menu I don't if it's possible for that to happen. ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
