Hi, I am running R 2.2.0 on the Windows XP x64. The mechanism of error hanlder seems different. It will take a very long time to pop up a error message diaglog box, even when some simple errors happen such as "Syntax error" or "object xxxx not found". Does anybody have the similar experience? Thanks a lot. BTW: everything works fine under 32-bit Windows X...

But for ARM without MSI-X kind mechanism guest can't get the interrupt reason through the only one irq hanlder (with one gsi resource). So I build a shared memory region to provide the interrupt reason instead of ISR regiser by qemu without bothering vhost. Then even there's only one irq with only one irq hanlder, it still can distinguish why irq occur. Li. > >> To get the interrupt reason...

Hm yeah there's a tiny race if your update handler for the pageflip can race with your vblank handler. That's impossible here since it's all done from the same hw irq hanlder, and since that is single-threaded there shouldn't be a problem, as long as vblank handling are pageflip are ordered correctly. Might be worth a note in the kerneldoc though that this function isn't perfectly foolproof. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://...

From: Li Liu <john.liuli at huawei.com> This set of patches try to implemet irqfd support of vhost-net based on virtio-mmio. I had posted a mail to talking about the status of vhost-net on kvm-arm refer to http://www.spinics.net/lists/kvm-arm/msg10804.html. Some dependent patches are listed in the mail too. Basically the vhost-net brings great performance improvements, almost 50%+.

First things first: Hi all! I''ve been sucked into prototype and script.aculo.us develpment thanks (because of?) the Symfony PHP framework... I''d like to implement a feature on some admin pages, but I can''t seem to find the right search term to google it; I want to ask the user to confirm exit of a page, if she has changed anything on the forms displayed on it. I have

This series extends QMP introspection to cover deprecation. Additionally, new option -compat lets you configure what to do when deprecated interfaces get used. This is intended for testing users of the management interfaces. It is experimental. -compat deprecated-input=<in-policy> configures what to do when deprecated input is received. Available policies: * accept: Accept deprecated

Apparently pre-nv50 pageflip events happen before the actual vblank period. Therefore that functionality got semi-disabled in commit af4870e406126b7ac0ae7c7ce5751f25ebe60f28 Author: Mario Kleiner <mario.kleiner.de at gmail.com> Date: Tue May 13 00:42:08 2014 +0200 drm/nouveau/kms/nv04-nv40: fix pageflip events via special case. Unfortunately that hack got uprooted in commit

When I submitted the qcow2 patch for blktap, suggestions came up that the qemu block drivers should be used also for blktap to eliminate the current code duplication in ioemu and blktap. The attached patch adds support for a tap:ioemu pseudo driver. Devices using this driver won''t use tapdisk (containing the code duplication) any more, but will connect to the qemu-dm of the domain.
