(pirqs\nthat correspond to physical edge interrupts) to handle_edge_irq.\n\nUse handle_fasteoi_irq for pirqs that need eoi (they generally\ncorrespond to level triggered irqs), no risk in loosing interrupts\nbecause we have to EOI the irq anyway.\n\nThis change has the following benefits:\n\n- it uses the very same handlers that Linux would use on native for the\nsame irqs (handle_edge_irq for edge irqs and msis, and\nhandle_fasteoi_irq for everything else);\n\n- it uses these handlers in the same way native code would use them: it\nlet Linux mask\\unmask and ack the irq when Linux want to mask\\unmask\nand ack the irq;\n\n- it fixes a problem occurring when a driver calls disable_irq() in its\nhandler: the old code was unconditionally unmasking the evtchn even if\nthe irq is disabled when irq_eoi was called.\n\nSee Documentation/DocBook/genericirq.tmpl for more informations.\n\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\n[v1: Fixed space/tab

The potentially interesting case here is PIRQ type\nevent channels associated with passed through PCI devices. However\neven in this case the guest has no direct interaction with the\nphysical GSI since that happens in the PCI backend.\n\nThe PV domain 0 and HVM guest cases are actually the same. In domain 0\ncase the kernel sees the host ACPI and GSIs (although it only sees the\nAPIC indirectly via the hypervisor) and in the HVM guest case it sees\nthe virtualised ACPI and emulated APICs. In these cases we start\nallocating dynamic IRQs at nr_irqs_gsi so that they cannot clash with\nany GSI.\n\nCurrently xen_allocate_irq_dynamic starts at nr_irqs and works\nbackwards looking for a free IRQ in order to (try and) avoid clashing\nwith GSIs used in domain 0 and in HVM guests.

Previous to this patch,\nthe \u0027find_unbound_irq\u0027 started looking at get_nr_hw_irqs() number.\nFor privileged domain where the ACPI information is available that\nreturns the upper-bound of what the GSIs. For non-privileged PV domains,\nwhere ACPI is no-existent the get_nr_hw_irqs() reports the IRQ_LEGACY (16).\nWith PCI passthrough enabled, and with PCI cards that have IRQs pinned\nto a higher number than 16 we collide with previously allocated IRQs.\nSpecifically the PCI IRQs collide with the IPI\u0027s for Xen functions\n(as they are allocated earlier).\nFor example:\n\n00:00.11 USB Controller: ATI Technologies Inc SB700 USB OHCI1 Controller (prog-if 10 [OHCI])\n\t...\n\tInterrupt: pin A routed to IRQ 18\n\n[root@localhost ~]# cat /proc/interrupts | head\n CPU0 CPU1 CPU2\n 16: 38186 0 0 xen-dyn-virq timer0\n 17: 149 0 0 xen-dyn-ipi spinlock0\n 18: 962 0 0 xen-dyn-ipi resched0\n\nand when the USB controller is loaded, the kernel reports:\nIRQ handler type mismatch for IRQ 18\ncurrent handler: resched0\n\nOne way to fix this is to reverse the logic when looking for un-used\nIRQ numbers and start with the highest available number. With that,\nwe would get:\n\n CPU0 CPU1 CPU2\n... snip ..\n292: 35 0 0 xen-dyn-ipi callfunc0\n293: 3992 0 0 xen-dyn-ipi resched0\n294: 224 0 0 xen-dyn-ipi spinlock0\n295: 57183 0 0 xen-dyn-virq timer0\nNMI: 0 0 0 Non-maskable interrupts\n.. snip ..\n\nAnd interrupts for PCI cards are now accessible.\n\nThis patch also includes the fix, found by Ian Campbell, titled\n\"xen: fix off-by-one error in find_unbound_irq.\"\n\n[v2: Added an explanation in the code]\n[v3: Rebased on top of tip/irq/core]\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\n" }, { "commit": "3b32f574a032bb5c93957317bd4ce5c3397d5a7b", "tree": "91cfba0cb671b7bf02a956303da87629ed239225", "parents": [ "1a60d05f40882303dad13f8f0e077e2e49ea8996" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Thu Aug 13 12:50:37 2009 -0700" }, "committer": { "name": "Konrad Rzeszutek Wilk", "email": "konrad.wilk@oracle.com", "time": "Mon Oct 18 10:41:44 2010 -0400" }, "message": "xen: statically initialize cpu_evtchn_mask_p\n\nSometimes cpu_evtchn_mask_p can get used early, before it has been\nallocated.
