+Subject: [PATCH v2] MIPS: perf: ath79: Fix perfcount IRQ assignment
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Currently it's not possible to use perf on ath79 due to genirq flags
+mismatch happening on static virtual IRQ 13 which is used for
+performance counters hardware IRQ 5.
+
+On TP-Link Archer C7v5:
+
+ CPU0
+ 2: 0 MIPS 2 ath9k
+ 4: 318 MIPS 4 19000000.eth
+ 7: 55034 MIPS 7 timer
+ 8: 1236 MISC 3 ttyS0
+ 12: 0 INTC 1 ehci_hcd:usb1
+ 13: 0 gpio-ath79 2 keys
+ 14: 0 gpio-ath79 5 keys
+ 15: 31 AR724X PCI 1 ath10k_pci
+
+ $ perf top
+ genirq: Flags mismatch irq 13. 00014c83 (mips_perf_pmu) vs. 00002003 (keys)
+
+On TP-Link Archer C7v4:
+
+ CPU0
+ 4: 0 MIPS 4 19000000.eth
+ 5: 7135 MIPS 5 1a000000.eth
+ 7: 98379 MIPS 7 timer
+ 8: 30 MISC 3 ttyS0
+ 12: 90028 INTC 0 ath9k
+ 13: 5520 INTC 1 ehci_hcd:usb1
+ 14: 4623 INTC 2 ehci_hcd:usb2
+ 15: 32844 AR724X PCI 1 ath10k_pci
+ 16: 0 gpio-ath79 16 keys
+ 23: 0 gpio-ath79 23 keys
+
+ $ perf top
+ genirq: Flags mismatch irq 13. 00014c80 (mips_perf_pmu) vs. 00000080 (ehci_hcd:usb1)
+
+This problem is happening, because currently statically assigned virtual
+IRQ 13 for performance counters is not claimed during the initialization
+of MIPS PMU during the bootup, so the IRQ subsystem doesn't know, that
+this interrupt isn't available for further use.
+
+So this patch fixes the issue by simply booking hardware IRQ 5 for MIPS PMU.

+
+Changes since v1:
+
+ I've incorporated two comments which I've received on IRC from blogic and
+ I've also reworded the commit message to match the changes in v2 of this
+ patch.
+
+ * use actual hardware perfcount IRQ 5 instead of the virtual IRQ 13
+ * dropped the CONFIG_PERF_EVENTS ifdef around irq_create_mapping
