Subject: [PATCH] MIPS: Malta: Fix interupt number of CBUS UART.
|
|
|
|
The CBUS UART's interrupt number was wrong conflicting with the interrupt
|
|
being tied to the Intel PIIX4. Since the PIIX4's interrupt is registered
|
|
before the CBUS UART which is not being used on most systems this would
|
|
not be noticed.
|
|
|
|
Attempts to open the ttyS2 CBUS UART would result in:
|
|
|
|
genirq: Flags mismatch irq 18. 00000000 (serial) vs. 00010000 (XT-PIC cascade)
|
|
serial_link_irq_chain: request failed: -16 for irq: 18
|
|
|
|
Qemu was written to match the kernel so will need to be fixed also.
