similar to: Will Xen support PCI add-on card for serial ports?

hi, I just tried the tip of the xen-unstable branch. It looks that the Xen supports 64bit BARs now?

I think we need this feature at least for debugging purpose, right? Or, do we already have this feature?

hi, I am wondering if anybody is doing Xen or Dom0 debugging with gdb here. If yes, could you show me the procedure of doing that?

Hi, In changeset 19130:c8962b24fb50, when using iommu=1, it goes into the hypervisor debugger. Why is this so? Thanks. -Alex _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I'm having issues connecting Garmin GPS 18 to COM1 on 9.1, I get nothing but silence. Identical setup works absolutely fine with Linux. I've got PPS wire connected to DCD, but that seems to make no difference on Linux, so I presume it shouldn't affect fbsd either. On Linux, I get: $ uname -a Linux ubuntu 3.8.0-19-generic #29-Ubuntu SMP Wed Apr 17 18:16:28 UTC 2013 x86_64 x86_64

I am a 62 year old beginner in Ubuntu. Thanks for any help, guidance, suggestions on this problem! I have used commands like the following to be certain that I have an active com port: dmesg | grep ttyS rm com1 ln -s /dev/ttyS0 com1 So I suspect the solution lies somewhere in WINE. If all else fails I will get a USB to SERIAL converter cable and try that. My wife has an Abbott Labs Freestyle

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the

hi, I am using xen-unstable version and I can use the serial port to debug DomU openSuSE Linux with kgdb very well. But it doesn''t work when I am trying to debug DomU WinXP with windbg. I happened to find this link http://www.evilbitz.com/2006/12/13/howto-debugging-a-remote-windows-hvm-under-xen-using-windbg/, but it still doesn''t work for me. Any suggestions about this?

Hi all, A recent thread inspired me to try getting a proper serial console working on a Supermicro X9SCL motherboard with IPMI. However I find that while I see loader messages and the getty I enabled after boot I don't get any kernel messages which does somewhat limit the utility.. The BMC creates COM3 (/dev/cuau2) which works with getty. I modified /boot/loader.conf like so..

Attached is a patch for shared interrupt between dom0 and HVM domain for vtd. Most of problem is caused by that we should inject interrupt to both domains and the physical interrupt deassertion then may be delayed by the device assigned to the HVM. The patch adds a timer, and the time out value is sufficient large to tolerant the delaying used to wait for the physical interrupt deassertion.

Attached are the patches to support super page with EPT. We only support 2M size. And shadow may still work fine with 4K pages. The patches can be split into 3 parts. Apply order is as attached. tool.diff To allocate 2M physical contiguous memory in guest except the first 2M and the last 2M. The first 2M covers special memory, and Xen use the last few pages in guest memory to do special

Keir, It''s a resending patch for the timeout mechanism to deal with the shared interrupt issue for vt-d enabled hvm guest. We modify the patch following your comments last time and make some other small fix: 1) We don''t touch the locking around the hvm_dpci_eoi(). 2) Remove the HZ from the TIME_OUT_PERIOD macro which may confuse others. 3) Add some

The patch attached is to set effective memory type for EPT according to the VT-d snoop control capability, and also includes some cleansup for EPT & VT-d both enabled.

The patch deals with the situation which guest OS uses unused page table pages as data pages and write data to them. The pages will still be grabbed by Xen as page table pages, and lots of unnecessary page faults occur. The patch will check if the data guest writes to the page table contains valid mfn or not, if not, we believe it is a data page now and then unshadow the page. The patch
