clk: qcom: smd-rpm: Add .recalc_rate hook for clk_smd_rpm_branch_ops

As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can
be used by branch clocks to report rate as well, rather than assuming
the rate is always same as parent clock.  This assumption doesn't hold
on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is
19.2MHz.

To get this work, XO buffered clocks need the following updates.

- Assign a correct rate rather than the fake one which is being used to
  generate binary value for clk_smd_rpm_req interface.

- Explicitly handle the clk_smd_rpm_req interface value for XO buffered
  clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).

Namhyung Kim [Fri, 10 Sep 2021 22:46:30 +0000 (15:46 -0700)]
perf tools: Allow build-id with trailing zeros

Currently perf saves a build-id with size but old versions assumes the
size of 20.  In case the build-id is less than 20 (like for MD5), it'd
fill the rest with 0s.

I saw a problem when old version of perf record saved a binary in the
build-id cache and new version of perf reads the data.  The symbols
should be read from the build-id cache (as the path no longer has the
same binary) but it failed due to mismatch in the build-id.

  symsrc__init: build id mismatch for /home/namhyung/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf.

The build-id event in the data has 20 byte build-ids, but it saw a
different size (16) when it reads the build-id of the elf file in the
build-id cache.

  $ readelf -n ~/.debug/.build-id/53/e4c2f42a4c61a2d632d92a72afa08f00000000/elf

      Build ID: 53e4c2f42a4c61a2d632d92a72afa08f

Let's fix this by allowing trailing zeros if the size is different.

3 years agoperf tools: Fix hybrid config terms list corruption
Adrian Hunter [Thu, 9 Sep 2021 12:55:08 +0000 (15:55 +0300)]
perf tools: Fix hybrid config terms list corruption

A config terms list was spliced twice, resulting in a never-ending loop
when the list was traversed. Fix by using list_splice_init() and copying
and freeing the lists as necessary.

This patch also depends on patch "perf tools: Factor out
copy_config_terms() and free_config_terms()"

Example on ADL:

 Before:

  # perf record -e '{intel_pt//,cycles/aux-sample-size=4096/pp}' uname &
  # jobs
  [1]+  Running                    perf record -e "{intel_pt//,cycles/aux-sample-size=4096/pp}" uname
  # perf top -E 10
    PerfTop:    4071 irqs/sec  kernel: 6.9%  exact: 100.0% lost: 0/0 drop: 0/0 [4000Hz cycles],  (all, 24 CPUs)
