vcc_3v3_reg and vcc_mmc1_reg are fixed regulators and don't need a reg property. Remove their unit-address. Solves: Warning (unit_address_vs_reg): Node /fixedregulator@0 has a unit name, but no reg property Warning (unit_address_vs_reg): Node /fixedregulator@1 has a unit name, but no reg

[PATCH 63/66] perf python: Add struct evsel into struct pyrf_event

From: Jiri Olsa To be able to find out event configuration info during sample parsing. Signed-off-by: Jiri Olsa Cc: David Ahern Cc: Namhyung Kim Cc: Peter Zijlstra Link:

[PATCH net-next 0/3] BPF event output helper improvements

This set adds improvements to the BPF event output helper to support non-linear data sampling, here specifically, for skb context. For details please see individual patches. The set is based against net-next tree. Thanks a lot! Daniel Borkmann (3): perf, events: add non-linear data support for

[PATCH 06/66] perf report: Introduce --stdio-color to setup the color output mode selection

From: Arnaldo Carvalho de Melo 'perf report --stdio' will colorize entries with most hits and possibly some other aspects of its output, but those colors gets suppressed if we redirect the output to a non-tty, allow keeping the colors by adding a new option, --stdio-color, now

[PATCH 21/66] perf quote: Disentangle headers

From: Arnaldo Carvalho de Melo No need to include stdio.h from quote.h, also forward declare strbuf. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim Cc: Wang Nan

[PATCH 12/66] perf trace beauty open_flags: Add more conditional defines

From: Arnaldo Carvalho de Melo Don't handle some flags only if they have its defines in headers at time of building, define what is missing. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung Kim

[PATCH 14/66] perf bench: Add missing pthread.h include for CPU_*() macros

[PATCH 13/66] tools: Introduce str_error_r()

From: Arnaldo Carvalho de Melo The tools so far have been using the strerror_r() GNU variant, that returns a string, be it the buffer passed or something else. But that, besides being tricky in cases where we expect that the function using strerror_r() returns the error

[PATCH 51/66] tools: Copy the bitsperlong.h files from the kernel

From: Arnaldo Carvalho de Melo We use it in bitops/__ffs.h and bitops/atomic.h, that we also got from the kernel, but were getting it from either newer systems that carry it in /usr/include, or from the kernel sources, that we decided not to touch from tools/ code. Fix it. Cc:

[PATCH 19/66] perf tools: Move syscall number fallbacks from perf-sys.h to tools/arch/x86/include/asm/

From: Arnaldo Carvalho de Melo And remove the empty tools/arch/x86/include/asm/unistd_{32,64}.h files introduced by eae7a755ee81 ("perf tools, x86: Build perf on older user-space as well"). This way we get closer to mirroring the kernel for cases where __NR_ can't be found for

[PATCH 56/66] perf symbols: Add Rust demangling

From: David Tolnay Rust demangling is another step after bfd demangling. Add a diagnosis to identify mangled Rust symbols based on the hash that the Rust mangler appends as the last path component, as well as other characteristics. Add a demangler to reconstruct the original

[PATCH net-next 2/3] bpf, perf: split bpf_perf_event_output

Split the bpf_perf_event_output() helper as a preparation into two parts. The newly bpf_perf_event_output() will prepare the raw record itself and test for unknown flags from BPF trace context, where the __bpf_perf_event_output() does the core work and will be reused later as well. Signed-off-by:

[PATCH net-next 3/3] bpf: avoid stack copy and use skb ctx for event output

This work improves bpf_skb_event_output() helper in two ways, i) it avoids that users need to unnecessary extract sampled skb data to stack first via bpf_skb_load_bytes() and then copy once again into the ring buffer slot, and ii) it avoids that only portions can be sampled with

[PATCH 4/4] ARM: dts: at91: sama5d4_ma5d4evk: fix regulator names

[PATCH 17/66] perf tests openat-syscall-tp-fields: Add some conditional defines

From: Arnaldo Carvalho de Melo These were only defined if _GNU_SOURCE was set in older glibc versions, check that and provide the defines in such cases. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa Cc: Namhyung

[PATCH 16/66] perf trace: Add conditional define for AT_FDCWD

[PATCH 29/66] tools lib traceevent: Use str_error_r()

From: Arnaldo Carvalho de Melo To make it portable to non-glibc systems, that follow the XSI variant instead of the GNU specific one that gets in place when _GNU_SOURCE is defined. Cc: Adrian Hunter Cc: David Ahern Cc: Jiri Olsa
