This is not only neat in terms of semantics but also avoids grabbing the global cgroup_threadgroup_rwsem for migration. - Daniel added !root xattr support to cgroupfs. Userland already uses xattrs on cgroupfs for bookkeeping. This will allow delegated cgroups to support such usages. - Prateek tried to make cpuset hotplug handling synchronous but that led to possible deadlock scenarios.

Add support for the Kendryte K210 RISC-V SoC. For now, this support only provides a simple sysctl driver allowing to setup the CPU and uart clock. This support is enabled through the new Kconfig option SOC_KENDRYTE and defines the config option CONFIG_K210_SYSCTL to enable the K210 SoC sysctl driver compilation. The sysctl driver also registers an early SoC initialization function allowing enabling the general purpose use of the 2MB of SRAM normally reserved for the SoC AI engine. This initialization function is automatically called before the dt early initialization using the flat dt root node compatible property matching the value "kendryte,k210".

2020-04-03riscv: Add SOC early init supportDamien Le Moal
Add a mechanism for early SoC initialization for platforms that need additional hardware initialization not possible through the regular device tree and drivers mechanism. With this, a SoC specific initialization function can be called very early, before DTB parsing is done by parse_dtb() in Linux RISC-V kernel setup code. This can be very useful for early hardware initialization for No-MMU kernels booted directly in M-mode because it is quite likely that no other booting stage exist prior to the No-MMU kernel. Example use of a SoC early initialization is as follows: static void vendor_abc_early_init(const void *fdt) { /* * some early init code here that can use simple matches * against the flat device tree file. */ } SOC_EARLY_INIT_DECLARE("vendor,abc", abc_early_init); This early initialization function is executed only if the flat device tree for the board has a 'compatible = "vendor,abc"' entry; Signed-off-by: Damien Le Moal <damien.lemoal@wdc.com> Signed-off-by: Anup Patel <anup.patel@wdc.com> Signed-off-by: Palmer Dabbelt <palmerdabbelt@google.com>

2020-04-03Revert "dm: always call blk_queue_split() in dm_process_bio()"Mike Snitzer
This reverts commit effd58c95f277744f75d6e08819ac859dbcbd351. blk_queue_split() is causing excessive IO splitting -- because blk_max_size_offset() depends on 'chunk_sectors' limit being set and if it isn't (as is the case for DM targets!) it falls back to splitting on a 'max_sectors' boundary regardless of offset. "Fix" this by reverting back to _not_ using blk_queue_split() in dm_process_bio() for normal IO (reads and writes). Long-term fix is still TBD but it should focus on training blk_max_size_offset() to call into a DM provided hook (to call DM's max_io_len()).

2020-04-03tracing: Do not allocate buffer in trace_find_next_entry() in atomicSteven Rostedt (VMware)
When dumping out the trace data in latency format, a check is made to peek at the next event to compare its timestamp to the current one, and if the delta is of a greater size, it will add a marker showing so. But to do this, it needs to save the current event otherwise peeking at the next event will remove the current event. To save the event, a temp buffer is used, and if the event is bigger than the temp buffer, the temp buffer is freed and a bigger buffer is allocated. This allocation is a problem when called in atomic context. The only way this gets called via atomic context is via ftrace_dump(). Thus, use a static buffer of 128 bytes (which covers most events), and if the event is bigger than that, simply return NULL. The callers of trace_find_next_entry() need to handle a NULL case, as that's what would happen if the allocation failed. Link: https://lore.kernel.org/r/20200326091256.GR11705@shao2-debian Fixes: ff895103a84ab ("tracing: Save off entry when peeking at next entry") Reported-by: kernel test robot <rong.a.chen@intel.com> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
2020-04-03KVM: SVM: Split svm_vcpu_run inline assembly to separate fileUros Bizjak
The compiler (GCC) does not like the situation, where there is inline assembly block that clobbers all available machine registers in the middle of the function. This situation can be found in function svm_vcpu_run in file kvm/svm.c and results in many register spills and fills to/from stack frame. This patch fixes the issue with the same approach as was done for VMX some time ago. The big inline assembly is moved to a separate assembly .S file, taking into account all ABI requirements. There are two main benefits of the above approach: * elimination of several register spills and fills to/from stack frame, and consequently smaller function .text size. The binary size of svm_vcpu_run is lowered from 2019 to 1626 bytes. * more efficient access to a register save array. Currently, register save array is accessed as: 7b00: 48 8b 98 28 02 00 00 mov 0x228(%rax),%rbx 7b07: 48 8b 88 18 02 00 00 mov 0x218(%rax),%rcx 7b0e: 48 8b 90 20 02 00 00 mov 0x220(%rax),%rdx and passing ia pointer to a register array as an argument to a function one gets: 12: 48 8b 48 08 mov 0x8(%rax),%rcx 16: 48 8b 50 10 mov 0x10(%rax),%rdx 1a: 48 8b 58 18 mov 0x18(%rax),%rbx As a result, the total size, considering that the new function size is 229 bytes, gets lowered by 164 bytes.

2020-04-03perf python: Fix clang detection to strip out options passed in $CCArnaldo Carvalho de Melo
The clang check in the python setup.py file expected $CC to be just the name of the compiler, not the compiler + options, i.e. all options were expected to be passed in $CFLAGS, this ends up making it fail in systems where CC is set to, e.g.: "aarch64-linaro-linux-gcc --sysroot=/oe/build/tmp/work/juno-linaro-linux/perf/1.0-r9/recipe-sysroot" Like this: $ python3 >>> from subprocess import Popen >>> a = Popen(["aarch64-linux-gnu-gcc --sysroot=/oe/build/tmp/work/juno-linaro-linux/perf/1.0-r9/recipe-sysroot", "-v"]) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.6/subprocess.py", line 729, in __init__ restore_signals, start_new_session) File "/usr/lib/python3.6/subprocess.py", line 1364, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: 'aarch64-linux-gnu-gcc --sysroot=/oe/build/tmp/work/juno-linaro-linux/perf/1.0-r9/recipe-sysroot': 'aarch64-linux-gnu-gcc --sysroot=/oe/build/tmp/work/juno-linaro-linux/perf/1.0-r9/recipe-sysroot' >>> Make it more robust, covering this case, by passing cc.split()[0] as the first arg to popen().

2020-04-03perf tools: Support Python 3.8+ in MakefileSam Lunt
Python 3.8 changed the output of 'python-config --ldflags' to no longer include the '-lpythonX.Y' flag (this apparently fixed an issue loading modules with a statically linked Python executable). The libpython feature check in linux/build/feature fails if the Python library is not included in FEATURE_CHECK_LDFLAGS-libpython variable. This adds a check in the Makefile to determine if PYTHON_CONFIG accepts the '--embed' flag and passes that flag alongside '--ldflags' if so. tools/perf is the only place the libpython feature check is used.

2020-04-03perf pmu-events x86: Use CPU_CLK_UNHALTED.THREAD in Kernel_Utilization metricJin Yao
The kernel utilization metric does multiplexing currently and is somewhat unreliable. The problem is that it uses two instances of the fixed counter, and the kernel has to multipleplex which causes errors. So should use CPU_CLK_UNHALTED.THREAD instead. Before: # perf stat -M Kernel_Utilization -- sleep 1 Performance counter stats for 'sleep 1': 1,419,425 cpu_clk_unhalted.ref_tsc:k <not counted> cpu_clk_unhalted.ref_tsc (0.00%) After: # perf stat -M Kernel_Utilization -- sleep 1 Performance counter stats for 'sleep 1': 746,688 cpu_clk_unhalted.thread:k # 0.7 Kernel_Utilization 1,088,348 cpu_clk_unhalted.thread Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Reviewed-by: Andi Kleen <ak@linux.intel.com> Reviewed-by: Kan Liang <kan.liang@linux.intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Jin Yao <yao.jin@intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lore.kernel.org/lkml/20200309013125.7559-1-yao.jin@linux.intel.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
