similar to: page-fault address in cr2 on stack frame

(Apologies for any duplication, yesterday's e-mail doesn't seem to have made it through moderation) I've had several recent crashes of the nouveau kernel driver over the past month or so. My suspicion is that Firefox is causing it. The screen goes black and then the computer reboots. Nothing much in the syslogs, however I've managed to get netconsole output. I've also run

I've had several recent crashes of the nouveau kernel driver over the past month or so. My suspicion is that Firefox is causing it. The screen goes black and then the computer reboots. Nothing much in the syslogs, however I've managed to get netconsole output. It happens very infrequently and I'm afraid I don't know how to reproduce it, however I'll be more than happy to

Hello, We''re curious about page fault handling in Xen-devel. In particular, during kernel boot-up, the kernel tests if the CPU "honours the WP bit". This causes a page fault with error code 3 (expected behavior). Does Xen still make a copy of the execution stack frame on the guest OS stack, as specified in the original "Xen and the Art of Virtualization" paper?

Package: xen-hypervisor-4.0-i386 Version: 4.0.1-4 This is the same machine referenced in http://bugs.debian.org/665413. It is an HP d530 SFF workstation (model DG784A) with 4GiB of RAM. It has run for years on the lenny xen + linux stack. If my notes are correct, it also ran smoothly for about a year with the lenny hypervisor + kernel and the squeeze userland. Rebooting into squeeze xen +

I would like to know approximately the overall execution flow when the guest O/S page fault - how is the page fault transfer to a page fault in the host O/S?

I''m porting a light weight kernel to run under the Xen hypervisor and have run into a problem while trying to switch to my page tables on x86-64. After a minor problem with switching to the new PML4 table that was cleared up when Mark Williamson suggested mapping everything read-only in the current map before switching, as well as switching the memory management code to use the

Hello. log of the crashing boot process: http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-14-xen331-linux-2.6.29-rc6-crash.txt 2.6.29-rc5 based pv_ops dom0 works on the same computer.. with the same Xen version. I tried with and without pci=nomsi. adding ''noapic'' doesn''t seem to help (I need that with 2.6.29-rc5 to make it work). Any ideas

Hi, I am reading shadow memory code in Xen 3.3.0, and have a question. In HVM guest, if a process writes a non-existing page, what happens: First, page fault occurs, and traps into Xen. Xen finds out that that page doesn''t exist in guest page table, so go back to guest. The guest fixes this fault in its page table, and writes that page again. Because that page doesn''t exist in

Hi, I''ve got a strange problem with XEN: I''m testing a 64-bit HVM-domain (a little OS written by me) with XEN 3.0.4 changeset 13138 on x86_64 (Dom0 and XEN taken from SLES 10 SP1). Always at the same point I get a page fault (which is okay) in PL=3 with strange interrupt data on the stack: the EIP is okay, but the CS saved is the TSS instead of my 64-bit user CS selector. I

Hi all, I''m trying to boot XEN. I get the following error though Panic on CPU 0: Early fatal page fault at e008:ff134570 (cr2=fffdf020, ec=0000) Reboot in five seconds... Unknown interrupt (cr2=fffdf020) My system has 2GB of RAM. Has anyone had the same problem and can give an hint? Thanks. In case anyone had done the same I''m doing, I''m actually downloading XEN

One could even debate whether reserved bit faults are always fatal (and should never be propagated to the guest)...

Hi How do we get the number of page faults done by a guest in a scheduling epoch? Assuming only one VCPU per guest, can I get it from vcpu_info[]? I hope this is not a vey trivial question :) thanks Chintu -- View this message in context: http://xen.1045712.n5.nabble.com/Getting-the-page-fault-count-for-domU-tp4847541p4847541.html Sent from the Xen - Dev mailing list
