* [S390] irqstats: split IPI interrupt accountingHeiko Carstens2011-10-30
| | | | | | | | | We use both the external call and emergency call IPIs to signal remote cpus. Therefore it makes sense to account them differently withing /proc/irqstats so we actually know what happened.

* [S390] fix mismatch in summation of I/O IRQ statisticsPeter Oberparleiter2011-10-30
| | | | | | | | | | | | | | | | | | | | | | | | | | Current IRQ statistics support does not show detail counts for I/O interrupts which are processed internally only. The result is a summation count which is way off such as this one: CPU0 CPU1 CPU2 I/O: 1331 710 442 [...] QAI: 15 16 16 [I/O] QDIO Adapter Interrupt QDI: 1 0 0 [I/O] QDIO Interrupt DAS: 706 645 381 [I/O] DASD C15: 26 10 0 [I/O] 3215 C70: 0 0 0 [I/O] 3270 TAP: 0 0 0 [I/O] Tape VMR: 0 0 0 [I/O] Unit Record Devices LCS: 0 0 0 [I/O] LCS CLW: 0 0 0 [I/O] CLAW CTC: 0 0 0 [I/O] CTC APB: 0 0 0 [I/O] AP Bus Fix this by moving I/O interrupt accounting into the common I/O layer.

* [S390] irq: have detailed statistics for interrupt typesHeiko Carstens2011-01-05
| | | | | | | | | | | | | | | | | | | | | | Up to now /proc/interrupts only has statistics for external and i/o interrupts but doesn't split up them any further. This patch adds a line for every single interrupt source so that it is possible to easier tell what the machine is/was doing. Part of the output now looks like this; CPU0 CPU2 CPU4 EXT: 3898 4232 2305 I/O: 782 315 245 CLK: 1029 1964 727 [EXT] Clock Comparator IPI: 2868 2267 1577 [EXT] Signal Processor TMR: 0 0 0 [EXT] CPU Timer TAL: 0 0 0 [EXT] Timing Alert PFL: 0 0 0 [EXT] Pseudo Page Fault [...] NMI: 0 1 1 [NMI] Machine Checks Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
