I have read http://www.yqcomputer.com/
and other items, but I still have not found the answers to the
1. The rs_init function in ./linux-2.4.21/drivers/char/serial.c
explicitly states "The interrupt of the serial console port can't be
shared." Does this include *ALL* interrupts? The code checks for
sharing only with other serial devices, not *ALL* types of devices
like I2C, RTC, etc.
2. While the presence of the comment about not sharing was nice, it
does not explain "why?" Why can't we share the serial console
interrupt? The serial console seems to work when I alter serial.c to
skip this check for the sharing of interrupts with the serial console.
3. Does the hardware platform matter? We are running Linux 2.4.21 on
an embedded XScale(ARM)-based board.
