This is a half-width, single-socket Epyc server board with an AST2500 BMC. This device tree is sufficient for basic OpenBMC functionality, but we'll need to add a few more devices (as driver support becomes available) before it's fully usable.

2022-02-21ARM: dts: aspeed: tacoma: Remove CFAM reset GPIOEddie James
witherspoon hardware and p9 chips have very sensitive requirements for the cfam-reset. We're seeing power faults with the kernel based cfam reset due to this. Could adapt the power application to use the new kernel based cfam reset interface but there's not a lot to be gained there since the power application is going away with p10 and this limitation is not present in p10.

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)
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.

2022-01-22perf evsel: Override attr->sample_period for non-libpfm4 eventsGerman Gomez
A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. 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 Jin
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>
