[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
I fail to come up with a use-case that just wants to add CPU/RAM without onlining it sooner or later. For virtual environments, you add CPU/RAM to use it and therefore want to online it once it appears. In a cloud environment (like ProfitBricks), it makes no sense to add CPU/RAM without using it, because you have to pay for it. Hot-add is supposed to work on recent kernels (>= 3.10). Kernel 3.2 had an issue, but I can't remember if adding CPU/RAM or onlining it causes the issue.

[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
Maintaining an ever-growing list of vendors is error-prone and TBH quite silly. Are there any CPUs where we *don't* want hot-add? If not, why can't the kernel just default to enabling this, instead of userspace unconditionally turning this on? But if hot-add is supposed to work everywhere, then for SRUs at least the udev rule could be simplified to drop the vendor check. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1233466 Title: Hot-Add Memory failing for lack of udev rule Status in linux package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Fix Released Bug description: It appears that the Hot-Add mechanism is not working because of lack of a udev rule.

[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
Hi Martin, Thanks for accommodating the request for the udev rule. The rule needs to live in the guest as Hyper-V does not understand udev rules. Yes, we did test with Andy's udev rule from comment 14 and it seems to work. Only issue we saw was that it seemed to suppress some of our other drivers such as: 1. hyperv-fb 2. hv_utils 3. hv_balloon It would be really helpful if you guys could do some unit testing to ensure that our drivers are loaded even after adding the udev rule then that would be great.

[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
Hi guys,
We went the alternate route of trying to convince kernel folks of fixing
this problem through a patch. Unfortunately, the patch was rejected. The
discussion involved is quoted below. Please also note that in the above
patch we can remove the CPU hotadd request command as that is
extraneous:
# CPU hotadd request
SUBSYSTEM==cpu, ACTION==add, DEVPATH==/devices/system/cpu/cpu*[0-9],
TEST==online, ATTR{online}=1
Please include the memory hotadd patch as not including it may lead to
kernel panics related to memory management.
Thanks,
Abhishek

Complexity, well, it's just a bit of code which belongs in the kernel.
The mentioned unconditional hotplug loop through userspace is
absolutely pointless. Such defaults never belong in userspace tools if
they do not involve data that is only available in userspace and
something would make a decision about that. Saying hello to
userspace and usrspace has a hardcoded yes in return makes no sense
at all. The kernel can just go ahead and do its job, like it does for
all other devices it finds too.
Sorry, but memory is different than all other devices. You never need a
mouse in order to add another mouse to the kernel.
I'll repaste something I said earlier in this thread:
A system under memory pressure is going to have troubles doing a
hot-add. You need memory to add memory. Of the two operations (add
and online), add is the one vastly more likely to fail. It has to
allocate several large swaths of contiguous physical memory. For that
reason, the system was designed so that you could add and online
separately. The intention was that you could add far in advance and
then online under memory pressure, with the online having *VASTLY*
smaller memory requirements and being much more likely to succeed.
So, no, it makes no sense to just have userspace always unconditionally
online all the memory that the kernel adds. But, the way it's set up,
we _have_ a method that can work under lots memory pressure, and it is
available for users that want it. It was designed 10 years ago, and
maybe it's outdated, or history has proved that nobody is going to use
it the way it was designed.
If I had it to do over again, I'd probably set up configurable per-node
sets of spare kernel metadata. That way, you could say make sure we
have enough memory reserved to add $FOO sections to node $BAR. Use
that for the largest allocations, then depend on PF_MEMALLOC to get us
enough for the other little bits along the way.
Also, if this is a problem, it's going to be a problem for *EVERY* user
of memory hotplug, not just hyperv. So, let's see it fixed generically
for *EVERY* user. Something along the lines of:
1. Come up with an interface that specifies a default policy for
newly-added memory sections. Currently, added memory gets added,
but not onlined, and the default should stay doing that.
2. Make sure that we at least WARN_ONCE() if someone tries to online an
already-kernel-onlined memory section. That way, if someone trips
over this new policy, we have a _chance_ of explaining to them what
is going on.
3. Think about what we do in the failure case where we are able to
add, but fail to online in the kernel. Do we tear the
newly-added structures down and back out of the operation, or do
we leave the memory added, but offline (what happens in the normal
case now)?

[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
Abhishek Gupta, did you really quote the right mails? Because those mails are just proving my point, it makes no sense to have an unconditional userspace rule which is just there to always enable new memory. To the contrary, as this is always going to involve more memory allocation (like it might spawn a new udev worker), it's much more prone to fail in userspace than in kernel space. This would make more sense if, as the thread suggests, you want to pre-add memory without activating it yet (I have no idea why this would be useful, but I don't claim to have a full understanding of all the use cases here), but then we shouldn't have that udev rule. Please include the memory hotadd patch That's another kernel patch not yet covered by the initial set of three (which should already be in precise)? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1233466 Title: Hot-Add Memory failing for lack of udev rule Status in “linux” package in Ubuntu: Fix Released Status in “systemd” package in Ubuntu: In Progress Bug description: It appears that the Hot-Add mechanism is not working because of lack of a udev rule.

Hi Martin, I will circle back with KY and reply by tomorrow morning on this.

We will be more than happy to work with you to provide an alternate solution.

[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
Ok I have built a test kernel containing the missing patch above which is here: http://people.canonical.com/~apw/hyperv-saucy/ I have also attempted to add the required rule to udev which is here: http://people.canonical.com/~apw/hyperv-saucy/udev/ If you could test those and confirm that this combination works as expected. Please note I have made some changes to the udev rule to firstly make it use modern ATTR manipulation, and secondly to only apply it for hyper-v guests.

[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
I am still testing the fix. It appears that the udev rule installs correctly but I see two issues: a) Memory demand from Ubuntu 13.10 is extraordinarily high on Hyper-V. It is likely to be a bug on our side and we will work on it. b) After applying all the packages under udev, our mouse driver is disabled for some reason. Please hold until tomorrow for more results.

[Kernel-packages] [Bug 1233466] Re: Hot-Add Memory failing for lack of udev rule
Please don't apply this udev rule as it is:
* It can be made *much* more efficient and avoid an extra shell with
SUBSYSTEM==memory, ACTION==add,
DEVPATH==/devices/system/memory/memory*[0-9], ATTR{online}=1
(same for the other rule)
* In this generic way they don't look plausible. If we *always* want
hotplugged CPUs and memory to be online (which sounds plausible), then
the kernel should do just that. It shouldn't require lots of extra
userspace overhead to always set a driver attribute to a constant value.
It is certainly ok as a workaround until the kernel gets fixed properly,
though.
* If this applies to Hyper-V only, it would be better to surround these
rules with some check if the system is actually running on this
hypervisor. This might happen via DMI data (like
ATTR{[dmi/id]product_version}==hyper-v), the presence of a Hyper-V
specific device/subsystem in sysfs, and so on. This
ATTR{[subsystem/device]attribute} syntax works generically by the way,
so that you can look at a device different than the one you are
currently selecting.
