similar to: [PATCH v4] x86: properly handle MSI-X unmask operation from guests

patch revision history ---------------------- v1: Initial patch to handle this issue involving changing the hypercall interface v2:Totally handled inside hypervisor. v3:Change some logics of handling msi-x pending unmask operations. v4:Some changes related to coding style according to Andrew Cooper''s comments v5:Some changes according to Jan''s comments, including a) remove

Guest needs the ability to enable and disable MSI-X interrupts by setting the MSI-X control bit, for a passed-through device. Guest is allowed to write MSI-X mask bit only if Xen *thinks* that mask is clear (interrupts enabled). If the mask is set by Xen (interrupts disabled), writes to mask bit by the guest is ignored. Currently, a write to MSI-X mask bit by the guest is silently ignored. A

Accelerated msix entry is initialized to zero when msixtbl_pt_register is called. This doesn''t match the value from qemu side, although pirq may already be mapped and binded in qemu side. Kernel will get wrong value when reading msix info. Signed-off-by: Zhenzhong Duan <zhenzhong.duan@oracle.com> Tested-by: Yuval Shaia <yuval.shaia@oracle.com> --- tools/libxc/xc_domain.c

This patch fixes size of ttbcr register (TCR_EL1 in case of AArch64) and it''s programming considering size in case of context switch. Currently ttbcr is defined as 32b register but for AArch64 TCR_EL1 size is 64b.

Hi developers, I met some domU issues and the log suggests missing interrupt. Details from here: http://www.gossamer-threads.com/lists/xen/users/263938#263938 In summary, this is the suspicious log: (XEN) vmsi.c:122:d32767 Unsupported delivery mode 3 I''ve checked the code in question and found that mode 3 is an ''reserved_1'' mode. I want to trace down the source of this

I''ve seen a recent report claiming that it works: http://linux-bsd-sharing.blogspot.pt/2012/10/howto-xen-413-windows-8-hvm-domu-with.html However, in my case, with a slightly different HW configuration the story is totally different. :-（ My config: HW: I7-3770 + AsRock H77M-ITX board Dom0: Debian Wheezy stock xen (v4.1.3) + Debian stock kernel (3.2.x / 3.6.x) 64 bit version. Note that

From: Yang Zhang <yang.z.zhang@Intel.com> The follwoing patches are adding the Posted Interrupt supporting to Xen: Posted Interrupt allows vAPIC interrupts to inject into guest directly without any vmexit. - When delivering a interrupt to guest, if target vcpu is running, update Posted-interrupt requests bitmap and send a notification event to the vcpu. Then the vcpu will handle this

Hi, I am curious to know why Xen disallows guest to change the mask bit of MSI-X vector control as show in the comment out section in msixtbl_write(). Our SR-IOV driver got driver reload failure because it cannot enable interrupt. /* Do not allow the mask bit to be changed. */ #if 0 /* XXX * As the mask bit is the only defined bit in the word, and as the * host MSI-X code

Hi- I am trying to pass an LSI SAS2008-based HBA (IBM M1015) through to an HVM Solaris VM, using Xen 4.2 unstable and the qemu-traditional device model.

Yippee, that worked!? I was able to unmask (systemctl unmask samba-ad-dc) and samba started.? wbinfo --ping-dc returns the new DC!? Also get correct groups and users with wbinfo

In <Xen In seterface Manual>, chapter 5 Event Channels, they say that:"Event Notifications can be masked by setting a flag; this is equivalent to disabling interrupts and can be used to ensure atomicity of certain operation in the guest kernel". My question is : I know that we can use ''xc_evtchn_unmask(xcehandle, port)'' to unmask an event channel , but I can not

Aah.. Sorry typo. systemctl unmask samba-ad-dc (umask / unmask ) systemctl enable samba-ad-dc systemctl start samba-ad-dc Im very buzy, so slow in responce atm, but if a service fails to upgrade and starts it gets masked. Unmasking is needed then. To make sure its all enable i also run extra enable. > -----Oorspronkelijk bericht----- > Van: Stefan G. Weichinger [mailto:lists at

I tried the Louis Van Belle's Debian backport of Samba 4.4.5 and I observed one obscure behaviour. I am running it on Debian 8.6.0.  I just run Samba as a NT4 PDC and do simple file sharing.  When my server is rebooted, my PCs cannot see the domain.  Everything seems fine when I checked the status of the Samba using "/etc/init.d/samba status".  However once I restart Samba

Hi, I have a problem while loading the "siar" program in R. When I am loading siar, system does not load convexhull. On the screen I have seen such writings. The following object(s) are masked from ‘package:spatstat’: convexhull How can I load the convexhull, how can I unmask from this package? I will be appreciated if you give advice about this. Best Sukran

Just backported 4.4.5 from debian sid to jessie. samba.service is masked there. If running as an fileserver the services are started via smbd.service,nmbd.service, winbind.service. There is an samba-ad-dc script which is masked by default. To get the ad-dc up and running with systemd one has to unmask samba-ad-dc.service and mask smbd.service,nmbd.service, winbind.service. This is the
