https://lore.kernel.org/lkml/[email protected]/
a near half year old adventure in trying to lower perf's dynamic
memory use. Bits like the memory overhead of opendir are on the
sidelines for now, too much fighting over how
distributions/C-libraries present getdents. These changes are more
good old fashioned replace an rb-tree with a sorted array and add
reference count tracking.
The changes migrate dsos code, the collection of dso structs, more
into the dsos.c/dsos.h files. As with maps and threads, this is done
so the internals can be changed - replacing a linked list (for fast
iteration) and an rb-tree (for fast finds) with a lazily sorted
array. The complexity of operations remain roughly the same, although
iterating an array is likely faster than iterating a linked list, the
memory usage is at least reduce by half.
As fixing the memory usage necessitates changing operations like find,
modify these operations so that they increment the reference count to
avoid races like a find in dsos and a remove. Similarly tighten up
lock usage so that operations working on dsos state hold the
appropriate lock.
Here are some questions (with answers) that I am expecting from reviewers:
- Why not refactor dso with accessors first and then do the other things?
My ambition with this change was to lower memory overhead not to
particularly clean up and fix dso. Fixing the memory overhead, by
refactoring and changing the internals, showed that locking discipline
and reference counting discipline was lacking. The later changes try
to fix these as a service to the community while I am changing the
code and to also ensure that code is correct (more correct than it was
wrt locking and reference counting than before the patches).
Reordering the patches to do the refactoring first will be a giant
pain. It will merge conflict with every other patch in the series and
is basically a request to reimplement everything from square 1. The
only thing I'd have in my favor would be how the code should look at
the end of the series, and reordering patches doesn't change the
eventual outcome of applying the patches. Note also, were I to send
the memory saving patches and then a week later send the API clean up
and reference counting fix patches the patches would be merged in the
order they are here. I've done my best, I know you may consider that
I'm adding to your reviewing overhead but I've also got to think about
the overhead to me.
- Please break apart this change...
The first changes are moving things, but when a broken API is spotted
like the missing get on dsos__find I put it in a change to move the
function and to add the missed get. Could this be two changes? Yes, it
could. Does moving code materially change the behavior of the tool?
No. I've done it in one patch to minimize churn and to some extent for
my sanity. Such changes are less than 100 lines of code and all
independently tested.
- The logic in dso around short, long name and id with sorting is weird
Yes, I've tried to make it less weird while retaining the existing
behavior. It would be easy to make a series of patches just cleaning
it up but I came here to save memory not change the dso API.
- Move the fixes in the 12th patch earlier.
This is possible but then impossible to test with reference count
checking. This does mean there are broken reference counts before the
patch is applied, but this is generally already the case. Yes, some
hypothetical person may decide to fork midway through this patch
series and my order would mean they wouldn't have a fix. I've done my
best while working within the bounds of my time and trying to avoid
churn.
v3. Rebases and drops merged "perf dso: Reorder variables to save
space in struct dso"

Move functions from machine and build-id to dsos. Pass dsos struct
rather than internal state. Rename some functions to better represent
which data structure they operate on.

2.44.0.478.gd926399ef9-goog
Move more functionality into dsos.c generally from machine, renaming
functions to match their new usage. The find function is made to
always "get" before returning a dso. Reduce the scope of locks in vdso
to match the locking paradigm.

DSOs were held on a list for fast iteration and in an rbtree for fast
finds. Switch to using a lazily sorted array where iteration is just
iterating through the array and binary searches are the same
complexity as searching the rbtree. The find may need to sort the
array first which does increase the complexity, but add operations
have lower complexity and overall the complexity should remain about
the same.
The set name operations on the dso just records that the array is no
longer sorted, avoiding complexity in rebalancing the rbtree. Tighter
locking discipline is enforced to avoid the array being resorted while
long and short names or ids are changed.
The array is smaller in size, replacing 6 pointers with 2, and so even
with extra allocated space in the array, the array may be 50%
unoccupied, the memory saving should be at least 2x.

written binary search. Const-ify some static functions to avoid

The dso pointer in dso_data is necessary for reference count checking
to account for the dso_data forming a global list of open dso's with
references to the dso. The dso pointer also allows for the indirection
that reference count checking needs. Outside of reference count
checking the indirection isn't needed and container_of is more
efficient and saves space.
The reference count won't be increased by placing items onto the
global list, matching how things were before the reference count
checking change, but we assert the dso is in dsos holding it live (and
that the set of open dsos is a subset of all dsos for the
machine). Update the DSO data tests so that they use a dsos struct to
make the invariant true.

Add reference count checking to struct dso, this can help with
implementing correct reference counting discipline. To avoid
RC_CHK_ACCESS everywhere, add accessor functions for the variables in
struct dso.
The majority of the change is mechanical in nature and not easy to
split up.
