I think thanks to previous patches regarding sysfs, this should be
very easy to review. The XML snippet that shows how the capablity XML
looks like can be seen in the second to last patch which adds test
for it.
Again, first few patches are trivial because I couldn't be bothered to
split the branch in two and writing two cover letters and moreover
those are patches for trivialities I stumbled upon during the work on
this series.
Also, this series is based upon Peter's news.xml validation against
RNG schema:

Previous discussion threads on the XML design and patches touching
this topic can be found here (not meant to be a complete list):

New subject: [libvirt] [PATCH 01/16] conf: Fix possible memleak in capabilities
If formatting NUMA topology fails, the function returns immediatelly,
but the buffer structure allocated on the stack references lot of
heap-allocated memory and that would get lost in such case.

what if I need another util function like:

do another copy and just modify path as:
if (virAsprintf(&path, "%s/%s", sysfs_resctrl_path, file) < 0)
is that okay for you to duplicated code like this?
This is not so common a way to adding utils functions.
If I need another `sysfs_system_path`, for /sys/fs/resctrl
I need to add a new variable sysfs_resctrl_path, then do a copy

Yeah, well, it's not nice to duplicate that much stuff. But for now I
can't think of any better way. Anyway, Erik started the discussion in
another thread, so we can think of something there.
Do you have a better idea?

New subject: [libvirt] [PATCH 09/16] util: Unify behaviour of the functions in sysfs.c
Make virSysfsGet*ValueString() functions use virSysfsGetValueString()
then we have one more allocation, but the code is cleaner and it's
easier to make sure the behaviour (e.g. return -2 on missing file)
isn't changed by mistake.

It will be helpful that we describe what cache, file looks like
even it’s straight enough to reading code.
What do you mean? The files look just like they look in the system.
It's a copy of what actually is under /sys/devices/system. The
description is in the kernel.

Can we add notes here to tell the value is in unite KiB ?
Well what if you want to use this for another file in the future? This
function will be able to read it even if the file has "1M" in it. Or
did you mean something else?

My mistake, it’s should B (not KiB), It’s okay.

This’s really good that you have work this out by expose all these out to capabilities,
and it will be much easy to let resctrl keep focus on cache allocation.
So if util/virresctrl.c would like to access some cache abilities, it will first get
virCapsPtr.host.caches,
right?
but I am not sure if that’s be okay to expose all cache information which we can not
do the allocation yet.
How can a user/admin to know from capabilities?

It looks like it's per cache level/type unique. But it's precisely just
what the kernel exposes to us. I'm not doing anything on top of that.

Well yeah, it'll probably extend the CacheBank struct.
but I am not sure if that’s be okay to expose all cache information
which we can not
do the allocation yet.
What's the harm?
How can a user/admin to know from capabilities?
Easily. The XML you see above just says what cache is on the host. If
any of the banks are allocatable, then it will have a sub-element. Is
there any problem with that?

think about I have a host has 2 Socket 22 core and 2 thread per core, I will have 88 cpus
so the cache bank will be a large list
2 for l3 , 44 for l2, 44 for l1d and 44 for l1c, not all of them are useful to users, and
the capabilities XML are boring.
Even though I am Okay to expose all of them.
I remember that Daniel has some comments for this in the RFC to not expose all caches of
the host if no cache allocation support yet.
Any way, no harm.

No problem, +1 to extend a sub-element .
Any suggestions for what’s it should be?
How about for l3:

think about I have a host has 2 Socket 22 core and 2 thread per core, I will have 88 cpus
so the cache bank will be a large list
2 for l3 , 44 for l2, 44 for l1d and 44 for l1c, not all of them are useful to users, and
the capabilities XML are boring.
You will have as many <bank/> elements as you have different caches. So
probably 1 for l3, 44 for l2 and 44 for each l1 (88).
Anyway, you are right, that's still 133 lines of stuff not everyone
cares about. And the capability XML is already pretty long.
Even though I am Okay to expose all of them.
I remember that Daniel has some comments for this in the RFC to not expose all caches of
the host if no cache allocation support yet.
I remember him saying that it's not necessary to expose all of it, but
for it to be able to be extendable, and in the future, able to expose
more caches. So now we see how the XML looks like, I'll change it in
next version to just report l3 in a way that we can switch it later on
by changing no more than one line of code.
Any way, no harm.
Yeah, there's no *real* harm, but you have a very good point that on
bigger systems the capability XML will be ridiculously gross to read =)

No problem, +1 to extend a sub-element .
Any suggestions for what’s it should be?
How about for l3:
<control min="2816" avail=“56320” cbm_len=“20” scope=‘both’
reserved=“2816"/>
Well, yes, kind of what you had in your patches. Wasn't it without the
'cbm_len' and 'avail'? The 'cbm_len' is avail/min, so it's
redundant
and avail is the same as the size of the whole cache, right? Also
'reserved' should not be there as that would have to be refreshed every
time the info is gathered and that's not what capabilities are for.
Also, if we say 'unified' instead of 'both', it sounds little more
consistent.
So basically, I'm thinking we were somewhere along the lines of:
<control min='2816' unit='B' scope=‘unified’/>
Or do I remember it wrong?

oh yeah, right!
for scope, it’s okay to use 'unified' to instead of ‘both’
for CDP enabled case would it be ?
1)
<control min='2816' unit='B' scope=‘data’/>
<control min='2816' unit='B' scope=‘instruction’/>
or
2)
<control min='2816' unit='B' scope=‘data+instruction’/>
or
3)
<control min='2816' unit='B' scope=‘cdp’/>
?
A correction, that would be <control min=‘2816 * 1024' unit='B'
scope=‘unified’/>
the unit B is kinds of small for l3 cache.
Thx Eli.

1)
<control min='2816' unit='B' scope=‘data’/>
<control min='2816' unit='B' scope=‘instruction’/>
I like this ^^.
or
2)
<control min='2816' unit='B' scope=‘data+instruction’/>
or
3)
<control min='2816' unit='B' scope=‘cdp’/>
?
A correction, that would be <control min=‘2816 * 1024' unit='B'
scope=‘unified’/>
the unit B is kinds of small for l3 cache.
Well, in that case just use unit='KiB' in case it's divisible.
Thx Eli.
