MIPS: Read CPU IRQ line that FDC to routed to

2015-03-31T10:04:12+00:00

Read the CPU IRQ line reportedly used for the Fast Debug Channel (FDC) interrupt from the IntCtl register and store it in cp0_fdc_irq where platform implementations of the new weak platform function get_c0_fdc_int() can refer to it.

MIPS: Add arch_trigger_all_cpu_backtrace() function

2014-11-24T06:44:49+00:00

Currently, arch_trigger_all_cpu_backtrace() is defined in only x86 and sparc which have an NMI. But in case of softlockup, it could be possible to dump backtrace of all cpus. and this could be helpful for debugging. for example, if system has 2 cpus. CPU 0 CPU 1 acquire read_lock() try to do write_lock() ,,, missing read_unlock() In this case, softlockup will occur becasuse CPU 0 does not call read_unlock(). And dump_stack() print only backtrace for "CPU 0". If CPU1's backtrace is printed it's very helpful.

MIPS: Add common plat_irq_dispatch declaration

2014-08-19T11:30:45+00:00

Add common declaration to get rid of following sparse warning: "symbol 'plat_irq_dispatch' was not declared. Should it be static?" Signed-off-by: Sergey Ryazanov Cc: Linux MIPS Patchwork: https://patchwork.linux-mips.org/patch/7539/ Signed-off-by: Ralf Baechle

MIPS: MT: Remove SMTC support

2014-05-23T22:07:01+00:00

Nobody is maintaining SMTC anymore and there also seems to be no userbase. Which is a pity - the SMTC technology primarily developed by Kevin D. Kissell is an ingenious demonstration for the MT ASE's power and elegance. Based on Markos Chandras patch https://patchwork.linux-mips.org/patch/6719/ which while very similar did no longer apply cleanly when I tried to merge it plus some additional post-SMTC cleanup - SMTC was a feature as tricky to remove as it was to merge once upon a time.

MIPS: Whitespace cleanup.

Having received another series of whitespace patches I decided to do this once and for all rather than dealing with this kind of patches trickling in forever. Signed-off-by: Ralf Baechle

MIPS: Provide a symbol for the legacy performance counter interrupt.

2012-07-06T21:56:00+00:00

Based on https://patchwork.linux-mips.org/patch/3576 - but this really deserves its own patchset and the symbol should also be used :) Signed-off-by: Ralf Baechle

irq_domain/mips: Allow irq_domain on MIPS

2012-02-24T16:47:23+00:00

This patch makes IRQ_DOMAIN usable on MIPS. It uses an ugly workaround to preserve current behaviour so that MIPS has time to add irq_domain registration to the irq controller drivers. The workaround will be removed in Linux v3.6 Signed-off-by: Grant Likely Cc: Ralf Baechle Cc: Rob Herring Cc: Thomas Gleixner Cc: linux-mips@linux-mips.org
