Hello,
I noticed the addition of the unsigned long *mb parameter in
xc_shadow_control(). If you have time, could you say a word or two
about what this parameter is used for?
Thanks,
Ryan

Subject: [Xen-devel] [RFC] New shadow paging code
We (Michael Fetterman, George Dunlap and I) have been working over the
last while on a full replacement for Xen's shadow pagetable support.
This mail contains some design notes, below; a patch against
xen-unstable, giving a snapshot of the current state of the new shadow
code, is at http://www.cl.cam.ac.uk/~tjd21/shadow2.patch
Comments on both are welcome, although the code is not finished -- in
particular there are both some optimizations and some tidying-up that
need to be done.
Cheers,
Tim.
----
The new shadow code (dubbed 'shadow2'), is designed as a replacement for
the current shadow code. It's been designed from the ground up to
support the following capabilities:
* Work for both paravirtualized and HVM guests. Our focus is on
Windows under HVM, since Linux guests can use paravirtual mechanisms for
faster memory management.
* Xen may be running in 2-, 3-, or 4-level paging mode. While booting,
guests may be in direct-access mode (no paging), or any paging level
less than or equal to Xen's current paging level. This means that we
must support 2-on-2, 2-on-3, 3-on-3, 3-on-4, and 4-on-4 paging modes.
* While bringing up secondary vcpus in an SMP system, the vcpus may all
be in different paging modes. We must support these simultaneously.
* Logdirty mode for live migration.
* We must work with paravirtualized drivers for HVM domains.
* We must work for guest superpages.
With this in mind, we have made several design choices:
* Do away with the "out-of-sync" mechanism to begin with. After a page
is promoted, emulate all writes to it until it is demoted again. This
makes the logic a lot simpler, and also reduces the overhead of demand
paging, which is one of the most common Windows modes. (See below for
more information on demand paging.)
* In the case of a size mismatch between guest pagetable entries and
host pagetable entries (i.e., 2-on-3 or 2-on-4, where guest pagetable
entries are 32 bits and host pagetable entires are 64 bits), a single
guest page may need to be shadowed by multiple shadow pages. In this
case, we always shadow the entire guest pagetable, rather than shadowing
only part at a time. We also keep the multiple backing shadow
pagetables physically contiguous in memory using a "buddy" allocator.
This allows us to use only one mfn value to designate the entire group
of mfns.
* We allocate a fixed amount of shadow memory at domain creation. This
is shared by all vcpus. When we need more shadow pages, we begin to
unshadow pages to free up more memory in approximately an LRU fashion.
* We keep the p2m maps for HVM domains in a pagetable format, so that we
can use them as the pagetables fo HVM guests in paging-disabled mode.
So far, we have had several successes. Demand-paging accesses have been
sped up by doing emulated writes rather than using the out-of-sync
mechanism. The out-of-sync mechanism requires three page faults, two of
which entail relative expensive shadow operations: marking a page out of
sync, and bringing it back into sync. In the case of HVM guests, the
faults also cause three expensive vmexit/vmenter cycles. Our emulated
writes requires only two page faults, and each fault is less expensive.
Also, the overhead of many individual shadow operations is less in the
newer code than in the old code.
We have a number of potential optimizations in mind for the near future:
* Removing writable mappings. As with the old code, when a guest pfn is
promoted to be a pagetable, we need to find and remove all writable
mappings to it, so that we can detect changes. Following the "start
simple, then optimize" principle, our current code does a brute-force
search through the shadows. Our tests indicate that when a page is
promoted to a pagetable, it generally has exactly one writable mapping
outstanding. This is true both for Windows and for Linux. We plan to
use this fact to keep a back-pointer to the last writable shadow pte of
a page in the page_info struct of a page. The few exceptions to the
rule can still be handled using brute-force search.
* Fast-pathing some faults. By storing the guest present / writable
flags in some of the spare bits of the guest pagetable, we can fast-path
certain operations, such as propagating a fault to the guest or updating
guest dirty and accessed bits, without needing to map the guest
pagetables. This should speed up some common faults, as well as reduce
cache footprint.
* Batch updates. There are times when guests do batch updates to
pagetables. At these times, it makes sense to give the guest write
access to the pagetables. At first this can be done simply by
unshadowing the page entirely. In the future, we can explore whether a a
"mark out of sync"
mechanism would speed things up. We may be able to have a more extreme
optimization for Linux fork(): when we detect Linux doing a fork(), we
can unshadow the entire user portion of the guest address space, to save
having to detect a "batch update" and unshadow each guest pagetable
individually.
* Full emulation of shadow page accesses. Currently, we allow read-only
access to guest pagetables. This requires us to emulate the dirty and
accessed bits of the guest pagetables, in turn requiring us to take page
faults. But how many of these dirty/accessed bits are actually read?
It may be more efficient, in certain circumstances, to emualte reads to
guest page tables as well as writes, taking the dirty and accessed bits
from the shadow pagetables.
* Teardown heuristics. If we can determine when a guest is destroying a
process, we can unshadow the whole address space at once. Failure to
detect when a process is being torn down will cause unnecessary
overhead:
if the guest pagetables of the destroyed process are recycled as data
pages, all writes to the pages will be emulated (in a rather expensive
manner) until the page is unshadowed. Even if the guest pagetables are
re-used for new process pagetables, constructing the address space will
be faster if unshadowed.
**************
Code Structure
**************
Our code must deal differently with all the different combinations of
shadow modes. However, we expect that once a guest reaches its target
paging mode, it will stay in that mode for a long time; and the host
will never change its paging mode. Rather than having a whole string of
ifs in the code based on the current guest and host paging modes, we
compile different code to deal with each pair of modes (2-on-2, 2-on-3,
2-on-4, 3-on-3, 3-on-4, 4-on-4). (Direct mode is implemented as a
special case of m-on-m, where m is the host's current paging level.)
While increasing the size of the hypervisor overall, this should greatly
decrease both the cache footprint of the shadow code and reduce pipeline
flushes from mispredicted branches.
To keep from having to maintain duplicate logic across 6 different bits
of code, we use a single source code file, and compiler directives to
specify mode-specific code. This file is shadow2.c, and is built once
with GUEST_PAGING_LEVELS and SHADOW_PAGING_LEVELS set to the
appropriate combination. The compiler is set to redefine the functions
from
sh2_[function_name]()
to
sh2_[function_name]__shadow_[m]_guest_[n]
for n-on-m mode.
At the end of shadow2.c is a structure containing function pointers for
each of the mode-specific functions; this is called shadow2_entry (and
is expanded by preprocessor directives using the __shadow_[m]_guest_[n]
naming convention). When a guest vcpu is put into a particular shadow
mode, an element of the vcpu struct is pointed to the appropriate
shadow2_entry struct. To call the appropriate function, one generally
calls shadow2_[function_name](v, [args]), which is generally implemented
after the following template:
[rettype] shadow2_[function_name](v, [args]) {
return v->arch.shadow2->[function_name](v, [args]); }

This shadow code allocates a fixed pool of memory per domain for
shadowing pagetables and building the phys-to-machine map (the old
shadow code just allocated pages from domheap as it required them).
The new parameter is used in shadow-control dom0 ops to set or get the
size of this pool, and set to NULL for all other operations.
Cheers,
Tim.

Hi,
A new version of the shadow2 patch is now available at
http://www.cl.cam.ac.uk/~tjd21/shadow2.patch
(md5: 20e56b90a32621ce3d1833a8d9fd769b shadow2.patch)
This version is more complete, and contains some optimizations over the
previous one, as well as various bug fixes. It is known to have
problems on 64bit and AMD systems right now. We also intend to add
support for log-dirty mode (PV migration) very soon, and benchmark to
decide which optimizations to keep.
Any feedback on this patch would be very welcome. Please have a play
with it if you're interested in shadow mode or HVM.
Cheers,
Tim.

Have you considered using binary patching (similar to the paravirt_ops
technique), so that the final shadow mode ops are invoked directly?

I don't think we would get very much benefit from it. In SMP HVM
guests, different vcpus can be in different shadow modes, so there would
still have to be a per-vcpu lookup to choose which mode to use.

Tim.

Tim,
I tried out your patch on a 4-way x86_64 ES7000 with 32GB of RAM. I only
tried it with an x86_64 hypervisor.
I was only able to bring up UP x86_32 HVM domains. I used the following
config.
kernel = "/usr/lib/xen/boot/hvmloader"
builder='hvm'
memory = 256
shadow_memory = 8
name = "winxp"
vif = [ 'type=ioemu, bridge=xenbr0' ]
disk = [ 'file:/mnt/xenlsg/xenimages/winxp.vmg,hda,w' ]
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'
sdl=0
vnc=1
serial='pty'
I tried bringing up as many x86_32 UP WinXP domains as I could. I found
that the qemu-dm process associated with each domain took up 50% cpu. So
when I tried to bring up the 9th domain I go the following error:
Error: Device 768 (vbd) could not be connected. Backend device not
found.
I have attached the output of top and xentop with 8 WinXP domains
running. I also kept seeing a few "(XEN) spurious IRQ irq got=-1
messages."
I was unable to bring up any SMP x86_32 domains. When I tried bringing
up a Win2003 Server with vcpus=2, only one CPU showed up in the domain.
I tried this with various combinations of acpi and apic.
Bringing up a domain with pae=1 crashes the system. I have attached the
output. I tried this with a Win2003 server image.
I could not bring up any x86_64 domains. When I tried a SLES10 x86_64
image I got a message saying "Your CPU does not support long mode. Use a
32-bit distribution"
So in a nutshell:
x86_32 hvm domain boot: pass
x86_32 pae hvm domain boot: fail
x86_64 hvm domain boot: fail
Please let me know if you need any more information.
Thanks,

Are you auto-ballooing memory from dom0 for these domains? One failure
mode of the memory allocation bug is that there is enough memory to
start the domain but not enough for qemu-dm to allocate its video card.
The domain then falls back to the much more cpu-intensive VGA support.

Thanks; this is a known bug but the fix didn't make it into that
patch. :(

I'll look into that; sounds like the results of CPUID are confusing the
linux kernel.
Cheers,
Tim.

I booted the system with dom0_mem=512M. So auto-ballooning does not take
place. I noticed that the same thing happens with xen-unstable without
the shadow2 patch.

Since you were hitting a bug with pae=1, I assume that error happened
with pae=0? In that case it's not surprising: x86_64 linux requires PAE
support (among other things) to boot, and "Your CPU does not support
long mode" is its generic response to not finding a required feature.

Ah yes, I had not set pae=1 when trying the x86_64 boot. I did not
realize that it was required. I thought all that I needed was ACPI=1 and
APIC=1.

A new version of the shadow2 patch is now available at
http://www.cl.cam.ac.uk/~tjd21/shadow2.patch
(md5: 3a094d3eebf328db887f495c022bf651)
This patch applies to version 0e32095a7b46 of -unstable.
It should fix the issues that have been seen with memory allocation and
with 64-bit HVM guests. SMP HVM guests may still have some problems.
Cheers,
Tim.

Tim,
I tried the patch on a 4-way x86_64 ES7000 32GB RAM with an x86_64
hypervisor.
I found that I am still unable to bring up domains with pae=1. I have
attached the error that I am seeing (hvm_pae.txt)
I then tried bringing up as many x86_32 WinXP domains as possible. The
qemu-dm process associated with each domain takes up 50% CPU. So I am
unable to bring up more than 8 (2 * NR_CPUS) domains.
Let me know if you need any more info.
Cheers,
Aravindh

I also found that if I don't bring up vncviewer, qemu-dm does not take
up 50% CPU. But I still fail trying to bring up the 9th domain with the
following error:
Error: Device 768 (vbd) could not be connected. Backend device not

Ooops!!! I realized why I could not bring up more than 8 domains. I was
using loopback devices for the winxp disks and max_loop was by default
set to 8. So once I upped the max_loop number I was able to bring up
more domains.
What I did was, I brought up 20 WinXP x86_32 domains without launching
their respective vncviewers. Once all the domains were up I launched 10
viewers and this caused qemu-dm of the 10 launched domains to hit 40-50%
CPU. All the viewers were sluggish and no real work could be done.

What guest OS were you using? How far through the boot process did it
get?

I am using x86_64 SLES10. It got up to the point of "Booting the kernel"
and then the crash happens. So it is very early in the boot.

Tim,
I can't get an HVM domU to finish booting. dom0 and domU are both running
64-bit SLES 10-beta10 with uniprocessor 2.6.16.13 kernels. The domU gets
as far as running grub and loading the kernel and initrd but then hangs.
xentop shows the domU running at 100% CPU.
For what its worth, I have tried all combinations of the pae, acpi, and
apic options. With pae=1 the domU dies (I assume qemu either exits or
dies). With pae=0 the domU hangs as described regardless of the settings
of acpi and apic.
The machine has four sockets with Intel Xeon 7020 (2.66 GHz dual core with
hyperthreading). Here is the config file for the domain:
(See attached file: hvm1.cfg)
Any other info you need? Anything I should examine or try?

Tim,
I tested this new patch in x86_64 mode, and here is the result for your reference.
(1)pae=0 UP IA32 VMX Pass
(2)pae=1 UP IA32 VMX Pass
(3)pae=0 UP IA32e VMX Complains "Your CPU does not support long mode. Use a 32bit disribution."
(4)pae=1 UP IA32e VMX VMX is destroyed automatically
The VMX's image is RHEL4U1.

In x86_64, when I set "pae=1" to start a x86_64 VMX, system crashed and got a
similar console output like yours. See pae_enable_ia32e.txt
When I set pae=1 to start a SMP x86_32 VMX, and VMX could not be stated,
and see attached console log pae_enable_ia32smp.txt.
To be concluded that in x86_64,
(1)pae=1, x86_64: system crash
(2)pae=1, x86_32 SMP: VMX could not be started with attached console log
(3)pae=0, x86_64: VMX could not be started with " it complains "Your CPU does not support long mode. Use a 32bit distribution"
(4)pae=0, x86_32 SMP: for pae enabled kernel, VMX could not started, while for pae disabled kernel, VMX could be started successfully.

Tim,
I tested your new patch in IA32e, and found that IA32 UP and SMP guest can
be successfully started, while IA32e VMX could not.
When IA32e VMX boots up, it complains "Your CPU does not support long mode. Use a 32bit distribution".
Here is the console log for ia32e VMX.
Ping

Tim, Hi
The following are from the previous version, but you might want to test
at least of them.
Testing Issues
=======================
We observed issues in the testing, especially in SMP VMX.
1. In IA32e platform, UP VMX or SMP VMX could not be started with error
info.
# xm cr -f config.up
Using config file "config.up".
Error: (12, 'Cannot allocate memory')
See attached xend.log
2. In IA32 platform, when starting one SMP VMX and one UP VMX together,
dom0 will reboot.
See attached console log
3. In IA32 platform, when starting 4 UP VMX together, dom0 will reboot
4. In IA32 platform, when starting 2 UP VMX and 2 UP xenU, 2 xenU and
one VMX could be started, and one VMX failed to boot.
5. In IA32pae platform, starting PAE enabled SMP VMX (vcpus=4), dom0
will reboot.
See attached console log.
6. In IA32pae platform, starting PAE disabled SMP VMX (vcpus=4), dom0
will reboot.
See attached console log.
7. In IA32pae platform, testing UP VMX from 128M to 3G with 128M step,
dom0 reboots.
8. In IA32 platform, running "halt -p" in SMP VMX and VMX shows "Badness
in send_IPI_mask_bitmask at arch/i386/kernel/smp.c:167"
9. In IA32pae platform, starting windows VMX cause xen0 reboot
See attached console log

Hi, Jun.
Thanks a lot for the test report; much appreciated.
Issue 1 was an bug in Xend's allocation of shadow memory; it is fixed
now. I'll get a new patch out as soon as I've investigated the
two HVM SPM issues.
Issues 2, 3, 6, 7 and 9 all look like the same issue, which was fixed in
yesterday's patch. Issue 4 I can't reproduce.
Cheers,
Tim.

We (Michael Fetterman, George Dunlap and I) have been working over the
last while on a full replacement for Xen's shadow pagetable support.
This mail contains some design notes, below; a patch against
xen-unstable, giving a snapshot of the current state of the new shadow
code, is at http://www.cl.cam.ac.uk/~tjd21/shadow2.patch
Comments on both are welcome, although the code is not finished -- in
particular there are both some optimizations and some tidying-up that
need to be done.
Cheers,
Tim.
----
The new shadow code (dubbed 'shadow2'), is designed as a replacement for
the current shadow code. It's been designed from the ground up to support
the following capabilities:
* Work for both paravirtualized and HVM guests. Our focus is on Windows
under HVM, since Linux guests can use paravirtual mechanisms for faster
memory management.
* Xen may be running in 2-, 3-, or 4-level paging mode. While booting,
guests may be in direct-access mode (no paging), or any paging level less
than or equal to Xen's current paging level. This means that we must
support 2-on-2, 2-on-3, 3-on-3, 3-on-4, and 4-on-4 paging modes.
* While bringing up secondary vcpus in an SMP system, the vcpus may all be
in different paging modes. We must support these simultaneously.
* Logdirty mode for live migration.
* We must work with paravirtualized drivers for HVM domains.
* We must work for guest superpages.
With this in mind, we have made several design choices:
* Do away with the "out-of-sync" mechanism to begin with. After a page is
promoted, emulate all writes to it until it is demoted again. This makes the
logic a lot simpler, and also reduces the overhead of demand paging, which
is one of the most common Windows modes. (See below for more information
on demand paging.)
* In the case of a size mismatch between guest pagetable entries and host
pagetable entries (i.e., 2-on-3 or 2-on-4, where guest pagetable entries
are 32 bits and host pagetable entires are 64 bits), a single guest page
may need to be shadowed by multiple shadow pages. In this case, we always
shadow the entire guest pagetable, rather than shadowing only part at a
time. We also keep the multiple backing shadow pagetables physically
contiguous in memory using a "buddy" allocator. This allows us to use only
one mfn value to designate the entire group of mfns.
* We allocate a fixed amount of shadow memory at domain creation. This is
shared by all vcpus. When we need more shadow pages, we begin to unshadow
pages to free up more memory in approximately an LRU fashion.
* We keep the p2m maps for HVM domains in a pagetable format, so that we
can use them as the pagetables fo HVM guests in paging-disabled mode.
So far, we have had several successes. Demand-paging accesses have been
sped up by doing emulated writes rather than using the out-of-sync
mechanism. The out-of-sync mechanism requires three page faults, two of
which entail relative expensive shadow operations: marking a page out of
sync, and bringing it back into sync. In the case of HVM guests, the
faults also cause three expensive vmexit/vmenter cycles. Our emulated
writes requires only two page faults, and each fault is less expensive.
Also, the overhead of many individual shadow operations is less in the newer
code than in the old code.
We have a number of potential optimizations in mind for the near future:
* Removing writable mappings. As with the old code, when a
guest pfn is promoted to be a pagetable, we need to find and remove all
writable mappings to it, so that we can detect changes. Following the
"start simple, then optimize" principle, our current code does a
brute-force search through the shadows. Our tests indicate that when a
page is promoted to a pagetable, it generally has exactly one writable
mapping outstanding. This is true both for Windows and for Linux. We plan
to use this fact to keep a back-pointer to the last writable shadow pte of
a page in the page_info struct of a page. The few exceptions to the rule
can still be handled using brute-force search.
* Fast-pathing some faults. By storing the guest present / writable flags
in some of the spare bits of the guest pagetable, we can fast-path certain
operations, such as propagating a fault to the guest or updating guest
dirty and accessed bits, without needing to map the guest pagetables. This
should speed up some common faults, as well as reduce cache footprint.
* Batch updates. There are times when guests do batch updates to
pagetables. At these times, it makes sense to give the guest write access
to the pagetables. At first this can be done simply by unshadowing the
page entirely. In the future, we can explore whether a a "mark out of sync"
mechanism would speed things up. We may be able to have a more extreme
optimization for Linux fork(): when we detect Linux doing a fork(), we can
unshadow the entire user portion of the guest address space, to save having
to detect a "batch update" and unshadow each guest pagetable individually.
* Full emulation of shadow page accesses. Currently, we allow read-only
access to guest pagetables. This requires us to emulate the dirty and
accessed bits of the guest pagetables, in turn requiring us to take page
faults. But how many of these dirty/accessed bits are actually read? It
may be more efficient, in certain circumstances, to emualte reads to guest
page tables as well as writes, taking the dirty and accessed bits from the
shadow pagetables.
* Teardown heuristics. If we can determine when a guest is destroying a
process, we can unshadow the whole address space at once. Failure to
detect when a process is being torn down will cause unnecessary overhead:
if the guest pagetables of the destroyed process are recycled as data
pages, all writes to the pages will be emulated (in a rather expensive
manner) until the page is unshadowed. Even if the guest pagetables are
re-used for new process pagetables, constructing the address space will be
faster if unshadowed.
**************
Code Structure
**************
Our code must deal differently with all the different combinations of
shadow modes. However, we expect that once a guest reaches its target
paging mode, it will stay in that mode for a long time; and the host will
never change its paging mode. Rather than having a whole string of ifs in
the code based on the current guest and host paging modes, we compile
different code to deal with each pair of modes (2-on-2, 2-on-3, 2-on-4,
3-on-3, 3-on-4, 4-on-4). (Direct mode is implemented as a special case of
m-on-m, where m is the host's current paging level.) While increasing the
size of the hypervisor overall, this should greatly decrease both the cache
footprint of the shadow code and reduce pipeline flushes from mispredicted
branches.
To keep from having to maintain duplicate logic across 6 different bits of
code, we use a single source code file, and compiler directives to specify
mode-specific code. This file is shadow2.c, and is built once with
GUEST_PAGING_LEVELS and SHADOW_PAGING_LEVELS set to the appropriate
combination. The compiler is set to redefine the functions from
sh2_[function_name]()
to
sh2_[function_name]__shadow_[m]_guest_[n]
for n-on-m mode.
At the end of shadow2.c is a structure containing function pointers for
each of the mode-specific functions; this is called shadow2_entry (and is
expanded by preprocessor directives using the __shadow_[m]_guest_[n] naming
convention). When a guest vcpu is put into a particular shadow mode, an
element of the vcpu struct is pointed to the appropriate shadow2_entry
struct. To call the appropriate function, one generally calls
shadow2_[function_name](v, [args]), which is generally implemented after
the following template:
[rettype] shadow2_[function_name](v, [args]) {
return v->arch.shadow2->[function_name](v, [args]);
}

Can you explain how this works? It is not obvious to me from the patch.
In shadow2.c there is in fact a whole string of #ifs. What mechanism
causes the file to be multiply compiled? Or do I misunderstand how this
works?
Also, can you comment on the differences and similarities with the
shadow code contributed by Ben Thomas?
thanks,
Mike Day

It's handled by the makefile runes that go into in xen/arch/x86/Makefile.
For each type of host, a number of shadow2_gX_on_sY.o files are
required, and the rule for shadow2_%.o compiles shadow2.c with the
appropriate definitions for GUEST_PAGING_LEVELS and SHADOW_PAGING_LEVELS.

There are some similarities: for example both patches allocate a pool of
shadow memory for each domain, rather than allocating from domheap on
the fly. Also, we're currently working on incorporating the idea of
storing guest present/writable bits in the shadow pte for fast-path of
"genuine" faults.
The major difference in structure is that the XI patch keeps the
"out-of-sync" algorithm of the old shadow code, letting guests write to
their pagetables and re-syncing the shadow on a fault. This works well
for linux's fork()/exit() behaviour, but for Windows, which mostly does
demand paging, it makes the cycle of fault-install-retry rather
expensive. Instead, the shadow2 patch emulates all writes to
pagetables, without ever letting the guest write to a shadowed page
directly.
XI also has a reverse-mapping mechanism for recording where all the
pagetable entries are that reference each page; this doubles the memory
cost of shadow mode, and adds some book-keeping, but avoids having to
search through all the shadows when revoking write access to a guest
page. We believe it's possible to use heuristics to speed up the
remove-all-writable-mappings process, without the memory overhead. For
example, just looking in the kernel's linear map works in 99.8% of cases
for Windows 2003 Server.
As for features, XI supports only HVM guests on 64-bit Xen; shadow2
supports 32-bit and PAE Xen as well, and PV guests. As I understand it,
there is no plan to make XI support any other modes. XI supports
shadowing superpages directly with superpages, which shadow2 does not
(yet).
Cheers,
Tim.
