  cutils: work around platform differences in strto{l,ul,ll,ull}

  Linux returns 0 if no conversion was made, while OS X and presumably
  the BSDs return EINVAL.  The OS X convention rejects more invalid
  inputs, so convert to it and adjust the test case.

  Windows returns 1 from strtoul and strtoull (instead of -1) for
  negative out-of-range input; fix it up.

  cpu-exec: fix lock hierarchy for user-mode emulation

  tb_lock has to be taken inside the mmap_lock (example:
  tb_invalidate_phys_range is called by target_mmap), but
  tb_link_page is taking the mmap_lock and it is called
  with the tb_lock held.

  To fix this, take the mmap_lock in tb_find_slow, not
  in tb_link_page.

  exec: make mmap_lock/mmap_unlock globally available

  There is some iffy lock hierarchy going on in translate-all.c.  To
  fix it, we need to take the mmap_lock in cpu-exec.c.  Make the
  functions globally available.

[Xen-devel] [PATCH v2 1/2] x86/msr: Carry on after a non-"safe" MSR access fails without !panic_on_oops

[Andy Lutomirski]

This demotes an OOPS and likely panic due to a failed non-"safe" MSR
access to a WARN_ON_ONCE and a return of zero (in the RDMSR case).
We still write a pr_info entry unconditionally for debugging.

To be clear, this type of failure should *not* happen.  This patch
exists to minimize the chance of nasty undebuggable failures due on
systems that used to work due to a now-fixed CONFIG_PARAVIRT=y bug.

My personal preference is to just not do this at all.  A couple people
disagree.  If we make the unsafe variants not oops, then I think we
want to have the nice loud warning, since these issues are bugs if
they happen.

We could certainly use the exception table for this, but it'll result
in bigger core, since each MSR access will need an exception table
entry and an associated fixup to call some helper that warns and sets
the result to zero.

I'd be happy to implement that, but only if it'll be applied.
Otherwise I'd rather just drop this patch and keep the rest of the
series.

Stefano,

I have two questions,

#1. Which qemu version is this igd stuff going into? 2.6?
#2. Is this igd stuff going into qemu-xen inside xen? Any plan to go 
into xen 4.6?


Thanks
Tiejun

No, this is wrong.

If you really want to do something like this, then just make all MSR
reads safe. So the only difference between "safe" and "unsafe" is that
the unsafe version just doesn't check the return value, and silently
just returns zero for reads (or writes nothing).

To quote Obi-Wan: "Use the exception table, Luke".

Because decoding instructions is just too ugly. We'll do it for CPU
errata where we might have to do it for user space code too (ie the
AMD prefetch mess), but for code that _we_ control? Hell no.

So NAK on this.

Re: [Xen-devel] vTPM ownership problem

[Zhenyang Feng]

Hi Quan,

Thank you in advance.

I have set  XSM_ENABLE ?=y in xen-4.3.0/Config.mk before install XEN.

I remove the vtpmmgr / vtpm disk and build it again. But the problem still
exists.

Here is vtpmmgr  / vtpm  instance log.  (Including executing

  cutils: work around platform differences in strto{l,ul,ll,ull}

  Linux returns 0 if no conversion was made, while OS X and presumably
  the BSDs return EINVAL.  The OS X convention rejects more invalid
  inputs, so convert to it and adjust the test case.

  Windows returns 1 from strtoul and strtoull (instead of -1) for
  negative out-of-range input; fix it up.

  cpu-exec: fix lock hierarchy for user-mode emulation

  tb_lock has to be taken inside the mmap_lock (example:
  tb_invalidate_phys_range is called by target_mmap), but
  tb_link_page is taking the mmap_lock and it is called
  with the tb_lock held.

  To fix this, take the mmap_lock in tb_find_slow, not
  in tb_link_page.

Hey everyone,

So, as a followup of what we were discussing in this thread:

   [Xen-devel] PV-vNUMA issue: topology is misinterpreted by the guest
   http://lists.xenproject.org/archives/html/xen-devel/2015-07/msg03241.html

I started looking in more details at scheduling domains in the Linux
kernel. Now, that thread was about CPUID and vNUMA, and their weird way
of interacting, while this thing I'm proposing here is completely
independent from them both.

In fact, no matter whether vNUMA is supported and enabled, and no matter
whether CPUID is reporting accurate, random, meaningful or completely
misleading information, I think that we should do something about how
scheduling domains are build.

Fact is, unless we use 1:1, and immutable (across all the guest
lifetime) pinning, scheduling domains should not be constructed, in
Linux, by looking at *any* topology information, because that just does
not make any sense, when vcpus move around.

Let me state this again (hoping to make myself as clear as possible): no
matter in  how much good shape we put CPUID support, no matter how
beautifully and consistently that will interact with both vNUMA,
licensing requirements and whatever else. It will be always possible for
vCPU #0 and vCPU #3 to be scheduled on two SMT threads at time t1, and
on two different NUMA nodes at time t2. Hence, the Linux scheduler
should really not skew his load balancing logic toward any of those two
situations, as neither of them could be considered correct (since
nothing is!).

For now, this only covers the PV case. HVM case shouldn't be any
different, but I haven't looked at how to make the same thing happen in
there as well.

OVERALL DESCRIPTION
===
What this RFC patch does is, in the Xen PV case, configure scheduling
domains in such a way that there is only one of them, spanning all the
pCPUs of the guest.

Note that the patch deals directly with scheduling domains, and there is
no need to alter the masks that will then be used for building and
reporting the topology (via CPUID, /proc/cpuinfo, /sysfs, etc.). That is
the main difference between it and the patch proposed by Juergen here:
http://lists.xenproject.org/archives/html/xen-devel/2015-07/msg05088.html

This means that when, in future, we will fix CPUID handling and make it
comply with whatever logic or requirements we want, that won't have  any
unexpected side effects on scheduling domains.

Information about how the scheduling domains are being constructed
during boot are available in `dmesg', if the kernel is booted with the
'sched_debug' parameter. It is also possible to look
at /proc/sys/kernel/sched_domain/cpu*, and at /proc/schedstat.

With the patch applied, only one scheduling domain is created, called
the 'VCPU' domain, spanning all the guest's (or Dom0's) vCPUs. You can
tell that from the fact that every cpu* folder
in /proc/sys/kernel/sched_domain/ only have one subdirectory
('domain0'), with all the tweaks and the tunables for our scheduling
domain.

EVALUATION
==
I've tested this with UnixBench, and by looking at Xen build time, on a
16, 24 and 48 pCPUs hosts. I've run the benchmarks in Dom0 only, for
now, but I plan to re-run them in DomUs soon (Juergen may be doing
something similar to this in DomU already, AFAUI).

I've run the benchmarks with and without the patch applied ('patched'
and 'vanilla', respectively, in the tables below), and with different
number of build jobs (in case of the Xen build) or of parallel copy of
the benchmarks (in the case of UnixBench).

What I get from the numbers is that the patch almost always brings
benefits, in some cases even huge ones. There are a couple of cases
where we regress, but always only slightly so, especially if comparing
that to the magnitude of some of the improvement that we get.

Bear also in mind that these results are gathered from Dom0, and without
any overcommitment at the vCPU level (i.e., nr. vCPUs == nr pCPUs). If
we move things in DomU and do overcommit at the Xen scheduler level, I
am expecting even better results.

REQUEST FOR COMMENTS

Basically, the kind of feedback I'd be really glad to hear is:
   - what you guys thing of the approach,


Yesterday at the end of the developer meeting we (Andrew, Elena and
myself) discussed this topic again.


Hey,

Sorry for replying so late, I've been on vacation from right after
XenSummit up until yesterday. :-)


Regarding a possible future scenario with credit2 eventually supporting
gang scheduling on hyperthreads (which is desirable due to security
reasons [side channel attack] and fairness) my patch seems to be more
suited for that direction than yours.


Ok. Just let me mention that 'Credit2 + gang scheduling' might not be
exactly around the corner (although, we can prioritize working on it if
we want).

Hi George / Dario,

Could you please confirm the above understanding is correct? (In fact, it is
Related to lazy context switch, right?) if so I can continue with the
pi_context_switch() way George suggested.

Thanks,
Feng

I just tried it.  rdmsrl_safe and friends definitely work fine in that
code.  I think that Linux's Xen startup code is buggy and fails to set
up early exception handling.

Try this (horribly whitespace damaged):

 static void __init early_identify_cpu(struct cpuinfo_x86 *c)
 {
+   u64 tmp;
 #ifdef CONFIG_X86_64
c->x86_clflush_size = 64;
c->x86_phys_bits = 36;
@@ -752,6 +753,9 @@ static void __init early_identify_cpu(struct cpuinfo_x86 *c)
c->cpu_index = 0;
filter_cpuid_features(c, false);

+   pr_err("trying to crash\n");
+   rdmsrl_safe(0x12345678, );
+

It works fine.  I bet it crashes on a Xen guest, though.  I assume
that Xen just works in most cases by luck.

Sorry for the late response, I was on leave last Friday.

Thanks for your discussions and suggestions. I have one question about option 1.
I find that there are two places where '_VPF_blocked' can get set: vcpu_block()
and do_poll(). After putting the logic in vcpu_block(), do we need to care about
do_poll(). I don't know the purpose of do_poll() and the usage case of it.
Dario/George, could you please share some knowledge about it? Thanks a lot!

Thanks,
Feng
