2018-11-05drm/amd/display: Retiring set_display_requirements in dm_pp_smu.h - part2Fatemeh Darbehani
[Why] In DCN we want direct DAL to SMU calls, with as little as possible interference by pplib. The reason for each pp_smu interface mapping to 1 SMU message is so we can have the sequencing of different SMU message in dal and shared across different OS. This will also simplify debugging as DAL owns this interaction and there's no confusion about division of ownership.

2018-11-05MIPS: Fix `dma_alloc_coherent' returning a non-coherent allocationMaciej W. Rozycki
Fix a MIPS `dma_alloc_coherent' regression from commit bc3ec75de545 ("dma-mapping: merge direct and noncoherent ops") that causes a cached allocation to be returned on noncoherent cache systems. This is due to an inverted check now used in the MIPS implementation of `arch_dma_alloc' on the result from `dma_direct_alloc_pages' before doing the cached-to-uncached mapping of the allocation address obtained. The mapping has to be done for a non-NULL rather than NULL result, because a NULL result means the allocation has failed. Invert the check for correct operation then. Signed-off-by: Maciej W.

2018-11-05perf top: Display the LBR stats in callchain entryJin Yao
'perf report' has supported the displaying of LBR stats (such as cycles, predicted%) in callchain entry. For example: $ perf report --branch-history --stdio --1.01%--intel_idle mwait.h:29 intel_idle cpufeature.h:164 (cycles:5) intel_idle cpufeature.h:164 (predicted:76.4%) intel_idle mwait.h:102 (cycles:41) intel_idle current.h:15 While 'perf top' doesn't support that. For example: $ perf top -a -b --call-graph branch - 13.86% 0.23% [kernel] [k] __x86_indirect_thunk_rax - 13.65% __x86_indirect_thunk_rax + 1.69% do_syscall_64 + 1.68% do_select + 1.41% ktime_get + 0.70% __schedule + 0.62% do_sys_poll 0.58% __x86_indirect_thunk_rax Actually it's very easy to enable this feature in 'perf top'.

2018-11-05perf stat: Handle different PMU names with common prefixThomas Richter
On s390 the CPU Measurement Facility for counters now supports 2 PMUs named cpum_cf (CPU Measurement Facility for counters) and cpum_cf_diag (CPU Measurement Facility for diagnostic counters) for one and the same CPU. Running command [root@s35lp76 perf]# ./perf stat -e tx_c_tend \ -- ~/mytests/cf-tx-events 1 Measuring transactions TX_C_TABORT_NO_SPECIAL: 0 expected:0 TX_C_TABORT_SPECIAL: 0 expected:0 TX_C_TEND: 1 expected:1 TX_NC_TABORT: 11 expected:11 TX_NC_TEND: 1 expected:1 Performance counter stats for '/root/mytests/cf-tx-events 1': 2 tx_c_tend 0.002120091 seconds time elapsed 0.000121000 seconds user 0.002127000 seconds sys [root@s35lp76 perf]# displays output which is unexpected (and wrong): 2 tx_c_tend The test program definitely triggers only one transaction, as shown in line 'TX_C_TEND: 1 expected:1'. This is caused by the following call sequence: pmu_lookup() scans and installs a PMU. +--> pmu_aliases() parses all aliases in directory .../<pmu-name>/events/* which are file names. +--> pmu_aliases_parse() Read each file in directory and create an new alias entry. This is done with +--> perf_pmu__new_alias() and +--> __perf_pmu__new_alias() which also check for identical alias names. After pmu_aliases() returns, a complete list of event names for this pmu has been created. Now function pmu_add_cpu_aliases() is called to add the events listed in the json | files to the alias list of the cpu. +--> perf_pmu__find_map() Returns a pointer to the json events. Now function pmu_add_cpu_aliases() scans through all events listed in the JSON files for this CPU. Each json event pmu name is compared with the current PMU being built up and if they mismatch, the json event is added to the current PMUs alias list. To avoid duplicate entries the following comparison is done: if (!is_arm_pmu_core(name)) { pname = pe->pmu ? pe->pmu : "cpu"; if (strncmp(pname, name, strlen(pname))) continue; } The culprit is the strncmp() function. Using current s390 PMU naming, the first PMU is 'cpum_cf' and a long list of events is added, among them 'tx_c_tend' When the second PMU named 'cpum_cf_diag' is added, only one event named 'CF_DIAG' is added by the pmu_aliases() function. Now function pmu_add_cpu_aliases() is invoked for PMU 'cpum_cf_diag'. Since the CPUID string is the same for both PMUs, json file events for PMU named 'cpum_cf' are added to the PMU 'cpm_cf_diag' This happens because the strncmp() actually compares: strncmp("cpum_cf", "cpum_cf_diag", 6); The first parameter is the pmu name taken from the event in the json file. The second parameter is the pmu name of the PMU currently being built. They are different, but the length of the compare only tests the common prefix and this returns 0(true) when it should return false. Now all events for PMU cpum_cf are added to the alias list for pmu cpum_cf_diag. Later on in function parse_events_add_pmu() the event 'tx_c_end' is searched in all available PMUs and found twice, adding it two times to the evsel_list global variable which is the root of all events. This results in a counter value of 2 instead of 1.

The page is still included in the response, so the response contains a page of bogus data. We need to adjust the page_ptr backwards to ensure we encode the next page into the correct place. We saw this triggered when concurrent directory modifications caused nfsd4_encode_direct_fattr() to return nfserr_noent, and the resulting call to xdr_truncate_encode() corrupted the READDIR reply.

2018-11-05compiler: remove __no_sanitize_address_or_inline againMartin Schwidefsky
The __no_sanitize_address_or_inline and __no_kasan_or_inline defines are almost identical. The only difference is that __no_kasan_or_inline does not have the 'notrace' attribute. To be able to replace __no_sanitize_address_or_inline with the older definition, add 'notrace' to __no_kasan_or_inline and change to two users of __no_sanitize_address_or_inline in the s390 code. The 'notrace' option is necessary for e.g. the __load_psw_mask function in arch/s390/include/asm/processor.h. Without the option it is possible to trace __load_psw_mask which leads to kernel stack overflow.

2018-11-05x86/build: Remove -pipe from KBUILD_CFLAGSNathan Chancellor
Commit 77b0bf55bc67 ("kbuild/Makefile: Prepare for using macros in inline assembly code to work around asm() related GCC inlining bugs") added -Wa,- to KBUILD_CFLAGS, which breaks compiling with Clang (hangs indefinitely at compiling init/main.o). This happens because while Clang accepts -pipe (and has it documented in its list of supported flags), it silently ignores it after this 2010 commit (thanks to Nick Desaulniers for tracking this down), meaning that gas just infinitely waits for stdin and never receives it. https://github.com/llvm-mirror/clang/commit/c19a12dc3d441bec62eed55e312b76c12d6d9022 Initially, I had suggested just add -Wa,- to KBUILD_CFLAGS when GCC was being used but that was before realizing it is because Clang doesn't do anything with -pipe. H. Peter Anvin suggested checking to see if -pipe gives us any gains out of GCC. Turns out it might actually be hurting: With -pipe: real 3m40.813s real 3m44.449s real 3m39.648s Without -pipe: real 3m38.492s real 3m38.335s real 3m38.975s The issue of -Wa,- being passed along to gas without -pipe being supported should still probably be fixed on the LLVM side (open issue: https://bugs.llvm.org/show_bug.cgi?id=39410) but this is not as much of a workaround anymore since it helps both GCC and Clang.

2018-11-05perf augmented_syscalls: Start collecting pathnames in the BPF programArnaldo Carvalho de Melo
This is the start of having the raw_syscalls:sys_enter BPF handler collecting pointer arguments, namely pathnames, and with two syscalls that have that pointer in different arguments, "open" as it as its first argument, "openat" as the second. With this in place the existing beautifiers in 'perf trace' works, those args are shown instead of just the pointer that comes with the syscalls tracepoints. This also serves to show and document pitfalls in the process of using just that place in the kernel (raw_syscalls:sys_enter) plus tables provided by userspace to collect syscall pointer arguments. One is the need to use a barrier, as suggested by Edward, to avoid clang optimizations that make the kernel BPF verifier to refuse loading our pointer contents collector. The end result should be a generic eBPF program that works in all architectures, with the differences amongst archs resolved by the userspace component, 'perf trace', that should get all its tables created automatically from the kernel components where they are defined, via string table constructors for things not expressed in BTF/DWARF (enums, structs, etc), and otherwise using those observability files (BTF).
