similar to: [PATCH] Intel VT-d: Dump IOMMU supported page sizes

The iommu is enabled by default when xen is booting and later disabled in iommu_setup() when no iommu is present. But under some circumstances iommu code can be called before iommu_setup() is processed. If there is no iommu available xen crashes. This can happen for example when panic(...) is called as introduced with the patch "x86-64: detect processors subject to AMD erratum #121 and

This fixes a bug in changeset 22526:7a5ee3800417, where the wrong value is read when deciding whether to flush the VTd tables. The effect is minor: in situations where the p2m entry is changed but the mfn is the same, the VTd tables will be unnecessarily flushed. old_entry is left untouched in the second case, since having a present old_entry will cause the an unnecessary check to be taken at

1: IOMMU: properly check whether interrupt remapping is enabled 2: AMD IOMMU: only disable when certain IVRS consistency checks fail 3: VT-d: deal with 5500/5520/X58 errata Patch 1 and 2 are version 2 of a previously submitted, then withdrawn patch following up after XSA-36.

Hello everyone, Reposting with after having applied the (minor) fixes suggested by Wei and Jan. Allen, if you can tell us what you think about this, or suggest someone else to ask some feedback to, if you''re no longer involved with VT-d, that would be great! :-) -- As already discussed here [1], dealing with IOMMU faults in interrupt context may cause nasty things to happen, up to

I wanted to run without 2MB and 1GB EPT pages, so I added "hap_2mb=0 hap_1gb=0" to the Xen grub command line. However I see the following on Xen boot: (XEN) EPT supports 2MB super page. When I bring up a guest I see a non-zero number of 2MB pages in the "xl create" output: xc: info: VIRTUAL MEMORY ARRANGEMENT: Loader: 0000000000100000->000000000017af10 TOTAL:

I recently switched from BroadVoice to VoicePulse Connect on my Asterisk box. Too many Meetme quality complaints (whether real or perceived). I had to make a choice to use IAX2 or SIP with VoicePulse. I first tried to go with SIP because I already had it working and all of our devices are SIP. Problem is that every time I turn my back, the Asterisk registration with the VoicePulse SIP server

Hi My situation: I have two pc''s with public ip''s (192.159.56.206(webserver) and 84.196.123.65(mail-gateway)) in the dmz. The firewall (84.196.123.66) is configures with proxyarp, so nothing is changed on the pc''s from when they were not behind the firewall (i.e. they don''t have the firewall as gateway (and they each have different gateways, only 84.196.123.65

Hi, I''m looking into write scaffold generators that will, amoung other things, scaffold active record associations (eg. generate select boxes for belongs_to where you can choose a parent object) for quicker prototyping. But... My question is: Is there anyway of finding out what associations exist from examining the lodel classes themselves or indeed any other way of finding out this

Up until now, freeing payloads on remote MST hubs that just had ports removed has almost never worked because we've been relying on port validation in order to stop us from accessing ports that have already been freed from memory, but ports which need their payloads released due to being removed will never be a valid part of the topology after they've been removed. Since we've
