      perf inject: Lazily allocate guest_event event_buf · 892d00fb
      Ian Rogers authored 
      The event_buf is 64kb (PERF_SAMPLE_SIZE_MAX) and stack allocated in
struct perf_inject. It is used for guest events that may not exist in
a file. Make the array allocation lazy to cut down on the stack usage.

      perf script: Remove some large stack allocations · e590e46b
      Ian Rogers authored 
      Some char buffers are stack allocated but in total they come to
24kb. Avoid Wstack-usage warnings by moving the arrays to being

      perf sched: Avoid large stack allocations · 232418a0
      Ian Rogers authored 
      Commit 5ded57ac ("perf inject: Remove static variables") moved
static variables to local, however, in this case 3 MAX_CPUS (4096)
sized arrays were moved onto the stack making the stack frame quite
large. Avoid the stack usage by dynamically allocating the arrays.

      perf cs-etm: Track exception level · 8d3031d3
      James Clark authored 
      Currently we assume all trace belongs to the host machine so when
the decoder should be looking at the guest kernel maps it can crash
because it looks at the host ones instead.

Avoid one scenario (guest kernel running at EL1) by assigning the
default guest machine to this trace. For userspace trace it's still not
possible to determine guest vs host, but the PIDs should help in this
case.

      perf cs-etm: Use previous thread for branch sample source IP · d67d8c87
      James Clark authored 
      Branch samples currently use the IP of the previous packet as the from
IP, and the IP of the current packet as the to IP. But it incorrectly
uses the current thread. In some cases like a jump into a different
exception level this will attribute to the incorrect process.

Fix it by tracking the previous thread in the same way the previous
packet is tracked.

      perf cs-etm: Only track threads instead of PID and TIDs · 951ccccd
      James Clark authored 
      PIDs and TIDs are already contained within the thread struct, so to
avoid inconsistencies drop the extra members on the etm queue and only
use the thread struct.

At the same time stop using the 'unknown' thread. In a later commit
we will be making samples from multiple machines so it will be better
to use the idle thread of each machine rather than overlapping unknown
threads. Using the idle thread is also better because kernel addresses
with a previously unknown thread will now be assigned to a real kernel
thread.

      perf map: Fix double 'struct map' reference free found with -DREFCNT_CHECKING=1 · 0d98a7af
      James Clark authored 
      When quitting after running a 'perf report', the refcount checker finds
some double frees. The issue is that map__put() is called on a function
argument so it removes the refcount wrapper that someone else was using.

Fix it by only calling map__put() on a reference that is owned by this
function.

Committer notes:

Narrowed the map_ref scope as suggested by Ian, removed the symbol-elf
part as it was already fixed by another patch, from Ian.

      perf srcline: Optimize comparision against SRCLINE_UNKNOWN · 922db21d
      Arnaldo Carvalho de Melo authored 
      This is a string constant that gets returned and then strcmp() around,
we can instead just do a pointer comparision.

That requires a new global variable to comply with these warnings from
some versions of clang and gcc:

  41    68.95 fedora:rawhide                : FAIL clang version 16.0.4 (Fedora 16.0.4-1.fc39)
    result of comparison against a string literal is unspecified (use an explicit string comparison function instead) [-Werror,-Wstring-compare]
            if (start_line != SRCLINE_UNKNOWN &&
                           ^  ~~~~~~~~~~~~~~~  41

Ack comments:

Agreed, the strcmps make me nervous as they won't distinguish heap from
a global meaning we could end up with things like pointers to freed
memory. The comparison with the global is always going to be same imo.
