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

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

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.

This patch moves the IO-APIC include inside #ifdef CONFIG_X86_IO_APIC , which is how Linux 2.6 has it. This is needed for architectures without asm/io_apic.h.

Hi, it looks like a few users of calloc had their arguments backwards. I checked the other users and they seem fine.

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

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

Attached and below are a patch that unifies the shutdown code paths in Xen, including those from EARLY_FAIL. This will facilitate the use of Intel(R) TXT for measured launch by ensuring that all shutdowns will call the necessary hook to tear down the measured environment. It also centralizes any future shutdown-related changes. The patch also postpones clearing the online status APs in

There was a patch committed the other day that should, at least, work around some of the behavior you describe. Optimized debug info is an area that's being worked on in ToT and previous releases are particularly bad. I'd use that. -eric On Mon, Apr 29, 2013 at 7:02 AM, Pankaj Gode <godepankaj at yahoo.com> wrote: > Hi All, > > Due to 'LowerDbgDeclare' call ( as

Hi All,   Due to 'LowerDbgDeclare' call ( as part of 'instruction combining' optimization), a local variable gets declared and initialized inside the basic blocks it is used in. Is there anyway I can avoid this ?   This is with reference with my previous question. http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-April/061644.html     Regards, Pankaj -------------- next part

Hi Eric,   Thanks for patch information. I have checked the patch with my code and I see that it works. But when I extract the variable and check the metadata information to retrieve the scope information, I do not get exact scope, after optimization. As you said that this is a work in progress, so can we expect full version on this in llvm3.3 release ?   Regards, Pankaj

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
