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.

For cases where we can we can automatically prove that\nthe file offset is always ignored, we use noop_llseek, which maintains\nthe current behavior of not returning an error from a seek.\n\nNew drivers should normally not use noop_llseek but instead use no_llseek\nand call nonseekable_open at open time.

To\nhelp with that, the Linux Xen MMU provides a lookup mechanism to\ntranslate the page frame numbers (PFN) to machine frame numbers (MFN)\nand vice-versa. The MFN are the \"real\" frame numbers. Furthermore\nmemory is not contiguous. Xen hypervisor stitches memory for guests\nfrom different pools, which means there is no guarantee that PFN\u003d\u003dMFN\nand PFN+1\u003d\u003dMFN+1. Lastly with Xen 4.0, pages (in debug mode) are\nallocated in descending order (high to low), meaning the guest might\nnever get any MFN\u0027s under the 4GB mark.\n\nSigned-off-by: Konrad Rzeszutek Wilk \u003ckonrad.wilk@oracle.com\u003e\nAcked-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nCc: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Albert Herranz \u003calbert_herranz@yahoo.es\u003e\nCc: Ian Campbell \u003cIan.Campbell@citrix.com\u003e\n" }, { "commit": "43df95c44e71d009b5a73f104ff183f73af9526f", "tree": "a51441c00ec7ee18d7bd62bc99602fcb0a1d553c", "parents": [ "5915100106b8f14a38053ad6c03a664d208aeaa2" ], "author": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Wed Jul 21 22:51:39 2010 -0700" }, "committer": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Mon Jul 26 23:13:27 2010 -0700" }, "message": "xenfs: enable for HVM domains too\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\n" }, { "commit": "c1c5413ad58cb73267d328e6020268aa2e50d8ca", "tree": "f2c66141ab8d9fdb7b16a13d4d510ad09b2430ed", "parents": [ "409771d258e9dd71c30f3c9520fd2b796ffc40f0" ], "author": { "name": "Stefano Stabellini", "email": "stefano.stabellini@eu.citrix.com", "time": "Fri May 14 12:44:30 2010 +0100" }, "committer": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Mon Jul 26 23:13:25 2010 -0700" }, "message": "x86: Unplug emulated disks and nics.\n\nAdd a xen_emul_unplug command line option to the kernel to unplug\nxen emulated disks and nics.\n\nSet the default value of xen_emul_unplug depending on whether or\nnot the Xen PV frontends and the Xen platform PCI driver have\nbeen compiled for this kernel (modules or built-in are both OK).\n\nThe user can specify xen_emul_unplug\u003dignore to enable PV drivers on HVM\neven if the host platform doesn\u0027t support unplug.\n\nSigned-off-by: Stefano Stabellini \u003cstefano.stabellini@eu.citrix.com\u003e\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\n" }, { "commit": "6280f190da4dd083f14f704be6b3314311a7eacb", "tree": "23b80ccd862117688eafa4c52ae6ad61fda2f082", "parents": [ "4c31a781144c1f556dfcda3277dafecd4e107d95" ], "author": { "name": "Paolo Bonzini", "email": "pbonzini@redhat.com", "time": "Wed Jun 23 18:30:15 2010 +0200" }, "committer": { "name": "Jeremy Fitzhardinge", "email": "jeremy.fitzhardinge@citrix.com", "time": "Mon Jul 26 10:05:05 2010 -0700" }, "message": "implement O_NONBLOCK for /proc/xen/xenbus\n\nThis patch implements O_NONBLOCK for /proc/xen/xenbus.
