Maybe 3.4.4 if there is some developer interest in cherry-picking the patches, and sufficient testing effort. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Ah, well if it already works then great. I thought there had been a previous report of it not working, and no subsequent fix. -- Keir On 16/05/2010 19:14, "Boris Derzhavets" <bderzhavets@yahoo.com> wrote:> However, my current environment just been built today via xen-3.4-testing.hg > :- > > root@ServerKoala:~# xm info > host : ServerKoala > release : 2.6.32.12 > version : #16 SMP Sun May 16 20:17:58 MSD 2010 > machine : x86_64 > nr_cpus : 4 > nr_nodes : 1 > cores_per_socket : 4 > threads_per_core : 1 > cpu_mhz : 2833 > hw_caps : > bfebfbff:20100800:00000000:00000140:0408e3fd:00000000:00000001:00000000 > virt_caps : hvm > total_memory : 8190 > free_memory : 2056 > node_to_cpu : node0:0-3 > node_to_memory : node0:2056 > xen_major : 3 > xen_minor : 4 > xen_extra : .3-rc7-pre > xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 > hvm-3.0-x86_32p hvm-3.0-x86_64 > xen_scheduler : credit > xen_pagesize : 4096 > platform_params : virt_start=0xffff800000000000 > xen_changeset : Thu May 13 10:40:19 2010 +0100 19967:d11bdc25b36d > cc_compiler : gcc version 4.4.1 (Ubuntu 4.4.1-4ubuntu9) > cc_compile_by : root > cc_compile_domain : > cc_compile_date : Sun May 16 19:40:04 MSD 2010 > xend_config_format : 4 > > Boris. > > > --- On Sun, 5/16/10, Keir Fraser <keir.fraser@eu.citrix.com> wrote: >> >> From: Keir Fraser <keir.fraser@eu.citrix.com> >> Subject: Re: Does Xen 3.4.3 support pvops kernel 2.6.32.12 ? >> To: "Boris Derzhavets" <bderzhavets@yahoo.com> >> Cc: "Xen-devel" <xen-devel@lists.xensource.com> >> Date: Sunday, May 16, 2010, 7:09 AM >> >> On 16/05/2010 11:54, "Boris Derzhavets" <bderzhavets@yahoo.com >> </mc/compose?to=bderzhavets@yahoo.com> > wrote: >> >>> Sorry, if i missed something in previous discussion (threads) . >>> But it sounds for me that answer is "NO" due to 3.4.3 >>> doesn''t have all required CSs for IOAPIC (2.6.32.X) back ported. >> >> Yeah, I think it misses the boat.

And they were for a device which was under IRQ 16 and was level low, while Xen assumed that all devices under IRQ 16 were edge high. The patch was to make it possible for hypercall to set IOAPIC pins below IRQ 16.
