sparc: drop use of extern for prototypes in arch/sparc/include/asm

2014-05-19T02:01:29+00:00

Drop extern for all prototypes and adjust alignment of parameters as required after the removal. In a few rare cases adjust linelength to conform to maximum 80 chars, and likewise in a few rare cases adjust alignment of parameters to static functions.

sparc32: fix sparse warnings in irq_32.c

2014-04-29T05:12:25+00:00

Fix following warnings: irq_32.c:239:5: warning: symbol 'sparc_floppy_request_irq' was not declared. Should it be static? irq_32.c:294:24: warning: symbol 'fdc_status' was not declared. Should it be static? irq_32.c:297:6: warning: symbol 'pdma_vaddr' was not declared. Should it be static? irq_32.c:300:15: warning: symbol 'pdma_size' was not declared. Should it be static? irq_32.c:303:14: warning: symbol 'doing_pdma' was not declared. Should it be static? irq_32.c:306:6: warning: symbol 'pdma_base' was not declared. Should it be static? irq_32.c:309:15: warning: symbol 'pdma_areasize' was not declared. Should it be static? irq_32.c:317:6: warning: symbol 'sparc_floppy_irq' was not declared. Should it be static? The floppy parts were all added to iasm/setup.h - no other header files looked obvious. floppy_32.h was not an option as this file can only be included once from the floppy driver.

sparc: Kill mmu_{un,}lockarea().

2012-05-13T20:23:16+00:00

These were used on sun4c during floppy data transfers since on that chip we had to lock the cpu mappings into the TLB because we cannot take a TLB miss during the assembler floppy interrupt handler that does the data transfer. That is no longer necessary since we've removed sun4c support, thus this stuff can disappear completely. Signed-off-by: David S. Miller

sparc32: code cleanup in floppy glue

2012-05-12T18:32:02+00:00

Small cleanup to improve readability. Dropped one test for sparc_cpu_model - we already know that only sun4m support floppy. Signed-off-by: Sam Ravnborg Signed-off-by: David S. Miller

sparc32: fix warning in floopy glue

2012-05-12T18:32:01+00:00

Fix following warning: arch/sparc/include/asm/floppy_32.h:342:5: warning: 'op' may be used uninitialized in this function The warning are legitimite and we can end up using op uninitialized. This fixes build with my gcc on UP. Signed-off-by: Sam Ravnborg Signed-off-by: David S. Miller

sparc: Clear out unused asm/machines.h values.

2012-05-12T03:45:18+00:00

Remove sun4 and sun4c machine ID values from asm/machines.h Also kill NUM_SUN_MACHINES, use ARRAY_SIZE instead. Kill asm/machines.h include and sun4c checks from asm/floppy_32.h Remove asm/machines.h include from setup_32.c and time_32.c, unused. Signed-off-by: David S. Miller

sparc32: genirq support

2011-04-20T05:11:40+00:00

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 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 Acked-by: Daniel Hellstrom Tested-by: Daniel Hellstrom Tested-by: Marcel van Nies Cc: Thomas Gleixner Signed-off-by: David S.
