sparc32: genirq support The conversion of sparc32 to genirq is based on original work done by David S. Miller. Daniel Hellstrom has helped in the conversion and implemented the shutdowm functionality. Marcel van Nies <morcles@gmail.com> has tested this on Sparc Station 20 Test status: sun4c - not tested sun4m,pci - not tested sun4m,sbus - tested (Sparc Classic, Sparc Station 5, Sparc Station 20) sun4d - not tested leon - tested on various combinations of leon boards, including SMP variants generic Introduce use of GENERIC_HARDIRQS and GENERIC_IRQ_SHOW Allocate 64 IRQs - which is enough even for SS2000 Use a table of irq_bucket to maintain uses IRQs irq_bucket is also used to chain several irq's that must be called when the same intrrupt is asserted Use irq_link to link a interrupt source to the irq All plafforms must now supply their own build_device_irq method handler_irq rewriten to use generic irq support floppy Read FLOPPY_IRQ from platform device Use generic request_irq to register the floppy interrupt Rewrote sparc_floppy_irq to use the generic irq support pcic: Introduce irq_chip Store mask in chip_data for use in mask/unmask functions Add build_device_irq for pcic Use pcic_build_device_irq in pci_time_init allocate virtual irqs in pcic_fill_irq sun4c: Introduce irq_chip Store mask in chip_data for use in mask/unmask functions Add build_device_irq for sun4c Use sun4c_build_device_irq in sun4c_init_timers sun4m: Introduce irq_chip Introduce dedicated mask/unmask methods Introduce sun4m_handler_data that allow easy access to necessary data in the mask/unmask functions Add a helper method to enable profile_timer (used from smp) Added sun4m_build_device_irq Use sun4m_build_device_irq in sun4m_init_timers TODO: There is no replacement for smp_rotate that always scheduled next CPU as interrupt target upon an interrupt sun4d: Introduce irq_chip Introduce dedicated mask/unmask methods Introduce sun4d_handler_data that allow easy access to necessary data in mask/unmask fuctions Rewrote sun4d_handler_irq to use generic irq support TODO: The original implmentation of enable/disable had: if (irq < NR_IRQS) return; The new implmentation does not distingush between SBUS and cpu interrupts. I am no sure what is right here. I assume we need to do something for the cpu interrupts. I have not succeeded booting my sun4d box (with or without this patch) and my understanding of this platfrom is limited. So I would be a bit suprised if this works. leon: Introduce irq_chip Store mask in chip_data for use in mask/unmask functions Add build_device_irq for leon Use leon_build_device_irq in leon_init_timers Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Daniel Hellstrom <daniel@gaisler.com> Tested-by: Daniel Hellstrom <daniel@gaisler.com> Tested-by: Marcel van Nies <morcles@gmail.com> Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: David S.
