similar to: [patch] IO-APIC in drivers/pci/quirks.c

This patch changes the dom0_ops structures as discussed in the thread "32/64-bit hypercall interface". Keir, I added a struct inside XENIF_PTR() to catch direct users in the general code; it was quite useful to have the compiler identify those spots. I have compiled x86_32 and run it with xm-test[1] under qemu. There are 63 passed tests, so that''s good. I still need to

Unlike x86 and apparently ia64, PowerPC delivers timer interrupts as a different exception than device interrupts. For PowerPC Xen, we emulate this exception rather than delivering timer events as virtual IRQs. This patch introduces no functional changes for x86 and ia64, but is a required change for xen/arch/ppc. Compile-tested on x86-32. Please apply. Signed-off-by: Hollis Blanchard

Hi, it looks like a few users of calloc had their arguments backwards. I checked the other users and they seem fine. Since one of those is in ioemu code, does that mean we (I?) will be submitting that bug to qemu upstream? -- Hollis Blanchard IBM Linux Technology Center Fix swapped calloc() arguments.

I think this is the last of the header fixes I''ve run across. Though it''s sometimes difficult to tell, I believe Xen/ia64 has asm/mm.h, flushtlb.h, page.h, and shadow.h. Please apply. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com> -- Hollis Blanchard IBM Linux Technology Center

On ia64/xen, pointer argument for the hypercall is passed by pseudo physical address (guest physical address.) So it is necessary to convert virtual address into pseudo physical address right before issuing hypercall. The frame work is called xencomm. This patch implements arch specific part.

As mentioned earlier, PowerPC''s atomic ops operate on longs, and we have made our *_bit() prototypes use long* (instead of void*) to warn us of problems at compile time. Here''s one caller that was flagged: test_and_set_bit(nr, &softirq_pending(cpu)) Accordingly, we need __softirq_pending to be long, not int. PowerPC is currently using a few files unmodified from the x86

The IRQ handling code requires pcidevs_lock to be held only for MSI interrupts. As the handling of which was now fully moved into msi.c (i.e. while applying fine without, the patch needs to be applied after the one titled "x86: split MSI IRQ chip"), io_apic.c now also doesn''t need to include PCI headers anymore.

This topic came up months ago (under the thread "make hypercall_preempt_check() a little more sensitive"), but since then, due to a misunderstanding, PPC has been running with a hack instead of a solution. So anyways, I''ve been digging into this again. PowerPC domains are allowed to write to the "interrupts enabled" bit (called External Exceptions, or EE) in the

Hi Ewan, I''m almost ready to integrate some PPC-specific stuff into xend, and I was wondering if you had a plan for how that should work. First example: the device tree data structure we talked about a few weeks ago. We will need to pass the config data to PPC code, probably in XendDomainInfo.initDomain(), and then pass the resulting data structure into libxc''s xc_linux_load()

Hi, Here is the patch fixing crash when apic=debug is used and APIC is not properly initialized. This issue appears during Xen Dom0 kernel boot (git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git, xen/stable-2.6.32.x head), however I think that patch is rather generic and should be applied to mainline kernel (it applies to Linux Kernel Ver. 2.6.35 and Ver. 2.6.32.19 with small fuzz).

Ever since 3.0.2 we''ve been carrying this patch in our products. Since there was no indication that there would be anything wrong with the ''new'' IO-APIC ack method added back then, we finally decided to drop this patch recently from SLE11, to find that the subsequent release candidate failed to work on at least on system without using "ioapic_ack=old".

Last year we had a discussion[1] about how the hypercall ABI unfortunately contains fields that change width between 32- and 64-bit builds. This is a huge problem as we come up on the python management stack for ppc64, since the distributions ship 32-bit python. A 32-bit python/libxc cannot currently manage a 64-bit hypervisor. I had a patch but was unable to test it, and some other things were
