2022-01-24gpio: merrifield: check the return value of devm_kstrdup()Xiaoke Wang1-0/+3
devm_kstrdup() returns pointer to allocated string on success, NULL on failure. So it is better to check the return value of it. Before, if devm_kstrdup() fails, pinctrl_dev_name will be NULL, then the retval below will be a negative error-code (inside gpiochip_add_pin_range(), pinctrl_find_and_add_gpio_range()->get_pinctrl_dev_from_devname() will finally check pinctrl_dev_name and return an error), so the failure of devm_kstrdup() can be only implicitly caught after a long call chain. While this patch is to explicitly catch the failure in time. Signed-off-by: Xiaoke Wang <xkernel.wang@foxmail.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
2022-01-24gpio: crystalcove: Set IRQ domain bus token to DOMAIN_BUS_WIREDHans de Goede1-1/+8
For the CRC PMIC we end up with multiple irq-domains with the same fwnode. One for the irqchip which demultiplexes the actual PMIC interrupt into interrupts for the various cells (known as the level 1 interrupts); And 2 more for the irqchips which are part of the crystal_cove_gpio and crystal_cove_charger cells. This leads to the following error being printed when CONFIG_GENERIC_IRQ_DEBUGFS is enabled: debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present! Set the bus token of the main IRQ domain to DOMAIN_BUS_WIRED to avoid this error, this also allows irq_find_matching_fwspec() to find the right domain if necessary. Note all 3 domain registering drivers need to set the IRQ domain bus token. This is necessary because the IRQ domain code defaults to creating the debugfs dir with just the fwnode name and then renames it when the bus token is set. So each one starts with the same default name and all 3 must be given a different name to avoid problems when one of the other drivers loads and starts with the same default name.

The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one. As the ftrace algorithm depends on it being sorted, bad things happen when it is not, and s390 experienced those bad things. Add a new config to tell the boot if the mcount table is sorted or not, and allow s390 to opt out of it" * tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: ftrace: Fix assuming build time sort works for s390
2022-01-23ftrace: Fix assuming build time sort works for s390Steven Rostedt (Google)2-3/+10
To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.

2022-01-22perf script: Fix printing 'phys_addr' failure issueYao Jin1-1/+1
Perf script was failed to print the phys_addr for SPE profiling. One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR attribute set, perf script then exits with error. Now referring to 'addr', use evsel__do_check_stype() to check the type. Before: # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\ store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3 # perf script -F pid,tid,addr,phys_addr Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field. After: # perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\ store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3 # perf script -F pid,tid,addr,phys_addr 4064384/4064384 ffff802f921be0d0 2f921be0d0 4064384/4064384 ffff802f921be0d0 2f921be0d0 Reviewed-by: German Gomez <german.gomez@arm.com> Signed-off-by: Yao Jin <jinyao5@huawei.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Hanjun Guo <guohanjun@huawei.com> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20220121065954.2121900-1-liwei391@huawei.com Signed-off-by: Wei Li <liwei391@huawei.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
