We crash on a benign-looking printk. The code around it got changed in -tip but checking those topic branches individually did not reproduce the bug. Bisection led to this commit: | d5edbc1f75420935b1ec7e65df10c8f81cea82de is first bad commit | commit d5edbc1f75420935b1ec7e65df10c8f81cea82de | Author: Jeremy Fitzhardinge <jeremy@goop.org> | Date: Mon May 26 23:31:22 2008 +0100 | | xen: add p2m mfn_list_list Which is somewhat surprising, as on native hardware Xen client side should have little to no side-effects. After some head scratching, it turns out the following happened: randconfig enabled the following Xen options: CONFIG_XEN=y CONFIG_XEN_MAX_DOMAIN_MEMORY=8 # CONFIG_XEN_BLKDEV_FRONTEND is not set # CONFIG_XEN_NETDEV_FRONTEND is not set CONFIG_HVC_XEN=y # CONFIG_XEN_BALLOON is not set which activated this piece of code in arch/x86/xen/mmu.c: > @@ -69,6 +69,13 @@ > __attribute__((section(".data.page_aligned"))) = > { [ 0 ...

In this case the size of p2m_top_mfn_list is not page aligned: 80b8d000 b p2m_top_mfn 80b8f000 b p2m_top_mfn_list 80b8f008 b softirq_stack 80b97008 b hardirq_stack 80b9f008 b bm_pte So all subsequent variables get unaligned which, depending on luck, breaks the kernel in various funny ways. In this case what killed the kernel first was the misaligned bootmap pte page, resulting in that creative crash above. Anyway, this was a fun bug to track down :-) I think the moral is that .bss.page_aligned is a dangerous construct in its current form, and the symptoms of breakage are very non-trivial, so i think we need build-time checks to make sure all symbols in .bss.page_aligned are truly page aligned. The Xen fix below gets the kernel booting again. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-05-27xen: maintain clock offset over save/restoreJeremy Fitzhardinge
Hook into the device model to make sure that timekeeping's resume handler is called. This deals with our clocksource's non-monotonicity over the save/restore. Explicitly call clock_has_changed() to make sure that all the timers get retriggered properly.

2008-05-27xen: implement save/restoreJeremy Fitzhardinge
This patch implements Xen save/restore and migration. Saving is triggered via xenbus, which is polled in drivers/xen/manage.c. When a suspend request comes in, the kernel prepares itself for saving by: 1 - Freeze all processes. This is primarily to prevent any partially-completed pagetable updates from confusing the suspend process. If CONFIG_PREEMPT isn't defined, then this isn't necessary. 2 - Suspend xenbus and other devices 3 - Stop_machine, to make sure all the other vcpus are quiescent. The Xen tools require the domain to run its save off vcpu0. 4 - Within the stop_machine state, it pins any unpinned pgds (under construction or destruction), performs canonicalizes various other pieces of state (mostly converting mfns to pfns), and finally 5 - Suspend the domain Restore reverses the steps used to save the domain, ending when all the frozen processes are thawed.

2008-05-27xenbus: rebind irq on restoreJeremy Fitzhardinge
When restoring, rebind the existing xenbus irq to the new xenbus event channel. (It turns out in practice that this is always the same, and is never updated on restore. That's a bug, but Xeno-linux has been like this for a long time, so it can't really be fixed.)

2008-05-27xen-console: add save/restoreJeremy Fitzhardinge
Add code to: 1. Deal with the console page being canonicalized. During save, the console's mfn in the start_info structure is canonicalized to a pfn. In order to deal with that, we always use a copy of the pfn and indirect off that all the time. However, we fall back to using the mfn if the pfn hasn't been initialized yet. 2. Restore the console event channel, and rebind it to the existing irq. Signed-off-by: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2008-05-27xen: fix unbind_from_irq()Jeremy Fitzhardinge
Rearrange the tests in unbind_from_irq() so that we can still unbind an irq even if the underlying event channel is bad. This allows a device driver to shuffle its irqs on save/restore before the underlying event channels have been fixed up.

2008-05-27xen: add rebind_evtchn_irqJeremy Fitzhardinge
Add rebind_evtchn_irq(), which will rebind an device driver's existing irq to a new event channel on restore. Since the new event channel will be masked and bound to vcpu0, we update the state accordingly and unmask the irq once everything is set up.

2008-05-27xen: add p2m mfn_list_listJeremy Fitzhardinge
When saving a domain, the Xen tools need to remap all our mfns to portable pfns. In order to remap our p2m table, it needs to know where all its pages are, so maintain the references to the p2m table for it to use.

2008-05-27xen: efficiently support a holey p2m tableJeremy Fitzhardinge
When using sparsemem and memory hotplug, the kernel's pseudo-physical address space can be discontigious. Previously this was dealt with by having the upper parts of the radix tree stubbed off. Unfortunately, this is incompatible with save/restore, which requires a complete p2m table. The solution is to have a special distinguished all-invalid p2m leaf page, which we can point all the hole areas at. This allows the tools to see a complete p2m table, but it only costs a page for all memory holes. It also simplifies the code since it removes a few special cases.

2008-05-27xen: add configurable max domain sizeJeremy Fitzhardinge
Add a config option to set the max size of a Xen domain. This is used to scale the size of the physical-to-machine array; it ends up using around 1 page/GByte, so there's no reason to be very restrictive. For a 32-bit guest, the default value of 8GB is probably sufficient; there's not much point in giving a 32-bit machine much more memory than that.

2008-05-27xen: make phys_to_machine structure dynamicJeremy Fitzhardinge
We now support the use of memory hotplug, so the physical to machine page mapping structure must be dynamic. This is implemented as a two-level radix tree structure, which allows us to efficiently incrementally allocate memory for the p2m table as new pages are added.

2008-05-27xen: make earlyprintk=xen work againJeremy Fitzhardinge
For some perverse reason, if you call add_preferred_console() it prevents setup_early_printk() from successfully enabling the boot console - unless you make it a preferred console too... Also, make xenboot console output distinct from normal console output, since it gets repeated when the console handover happens, and the duplicated output is confusing without disambiguation.

2008-05-27xen pvfb: Dynamic mode support (screen resizing)Markus Armbruster
The pvfb backend indicates dynamic mode support by creating node feature_resize with a non-zero value in its xenstore directory. xen-fbfront sends a resize notification event on mode change. Fully backwards compatible both ways. Framebuffer size and initial resolution can be controlled through kernel parameter xen_fbfront.video. The backend enforces a separate size limit, which it advertises in node videoram in its xenstore directory. xen-kbdfront gets the maximum screen resolution from nodes width and height in the backend's xenstore directory instead of hardcoding it. Additional goodie: support for larger framebuffers (512M on a 64-bit system with 4K pages). Changing the number of bits per pixels dynamically is not supported, yet.

2008-05-27xen: Enable console tty by default in domU if it's not a dummyMarkus Armbruster
Without console= arguments on the kernel command line, the first console to register becomes enabled and the preferred console (the one behind /dev/console). This is normally tty (assuming CONFIG_VT_CONSOLE is enabled, which it commonly is). This is okay as long tty is a useful console. But unless we have the PV framebuffer, and it is enabled for this domain, tty0 in domU is merely a dummy. In that case, we want the preferred console to be the Xen console hvc0, and we want it without having to fiddle with the kernel command line. Commit b8c2d3dfbc117dff26058fbac316b8acfc2cb5f7 did that for us. Since we now have the PV framebuffer, we want to enable and prefer tty again, but only when PVFB is enabled. But even then we still want to enable the Xen console as well. Problem: when tty registers, we can't yet know whether the PVFB is enabled. By the time we can know (xenstore is up), the console setup game is over. Solution: enable console tty by default, but keep hvc as the preferred console. Change the preferred console to tty when PVFB probes successfully, unless we've been given console kernel parameters.
