s390/pci: base support Add PCI support for s390, (only 64 bit mode is supported by hardware): - PCI facility tests - PCI instructions: pcilg, pcistg, pcistb, stpcifc, mpcifc, rpcit - map readb/w/l/q and writeb/w/l/q to pcilg and pcistg instructions - pci_iomap implementation - memcpy_fromio/toio - pci_root_ops using special pcilg/pcistg - device, bus and domain allocation Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> 2012-11-29 18:50:30 +07:00			`#`

s390: convert interrupt handling to use generic hardirq With the introduction of PCI it became apparent that s390 should convert to generic hardirqs as too many drivers do not have the correct dependency for GENERIC_HARDIRQS. On the architecture level s390 does not have irq lines. It has external interrupts, I/O interrupts and adapter interrupts. This patch hard-codes all external interrupts as irq #1, all I/O interrupts as irq #2 and all adapter interrupts as irq #3. The additional information from the lowcore associated with the interrupt is stored in the pt_regs of the interrupt frame, where the interrupt handler can pick it up. For PCI/MSI interrupts the adapter interrupt handler scans the relevant bit fields and calls generic_handle_irq with the virtual irq number for the MSI interrupt.

s390/kernel: add system calls for PCI memory access Add the new __NR_s390_pci_mmio_write and __NR_s390_pci_mmio_read system calls to allow user space applications to access device PCI I/O memory pages on s390x platform.
