2018-03-21ktest: Set do_not_reboot=y for CONFIG_BISECT_TYPE=buildScott Wood1-1/+2
Currently setting do_not_reboot is triggered by simple builds and bisect builds, but not config bisect builds. Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Scott Wood <[email protected]> Signed-off-by: Steven Rostedt (VMware) <[email protected]>
2018-03-21ktest: Set buildonly=1 for CONFIG_BISECT_TYPE=buildScott Wood1-13/+5
Rather than adding a third copy of the same logic, rework it to cover all three buildonly cases at once. In the future, please consider using the same variable to perform the same function regardless of context...

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-03-21 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add a BPF hook for sendmsg and sendfile by reusing the ULP infrastructure and sockmap. Three helpers are added along with this, bpf_msg_apply_bytes(), bpf_msg_cork_bytes(), and bpf_msg_pull_data(). The first is used to tell for how many bytes the verdict should be applied to, the second to tell that x bytes need to be queued first to retrigger the BPF program for a verdict, and the third helper is mainly for the sendfile case to pull in data for making it private for reading and/or writing, from John. 2) Improve address to symbol resolution of user stack traces in BPF stackmap. Currently, the latter stores the address for each entry in the call trace, however to map these addresses to user space files, it is necessary to maintain the mapping from these virtual addresses to symbols in the binary which is not practical for system-wide profiling. Instead, this option for the stackmap rather stores the ELF build id and offset for the call trace entries, from Song. 3) Add support that allows BPF programs attached to perf events to read the address values recorded with the perf events. They are requested through PERF_SAMPLE_ADDR via perf_event_open(). Main motivation behind it is to support building memory or lock access profiling and tracing tools with the help of BPF, from Teng. 4) Several improvements to the tools/bpf/ Makefiles. The 'make bpf' in the tools directory does not provide the standard quiet output except for bpftool and it also does not respect specifying a build output directory. 'make bpf_install' command neither respects specified destination nor prefix, all from Jiri. In addition, Jakub fixes several other minor issues in the Makefiles on top of that, e.g. fixing dependency paths, phony targets and more. 5) Various doc updates e.g. add a comment for BPF fs about reserved names to make the dentry lookup from there a bit more obvious, and a comment to the bpf_devel_QA file in order to explain the diff between native and bpf target clang usage with regards to pointer size, from Quentin and Daniel. ==================== Signed-off-by: David S.

Simply telling a new user to edit "the config file" without giving any hints on where that file should go, what it should be named, or where a template can be found, is not particularly helpful.

2018-03-21perf annotate browser: Add 'P' hotkey to dump annotation to fileArnaldo Carvalho de Melo3-0/+37
Just like we have in the histograms browser used as the main screen for 'perf top --tui' and 'perf report --tui', to print the current annotation to a file with a named composed by the symbol name and the ".annotation" suffix. Here is one example of pressing 'A' on 'perf top' to live annotate a kernel function and then press 'P' to dump that annotation, the resulting file: # cat _raw_spin_lock_irqsave.annotation _raw_spin_lock_irqsave() /proc/kcore Event: cycles:ppp 7.14 nop 21.43 push %rbx 7.14 pushfq pop %rax nop mov %rax,%rbx cli nop xor %eax,%eax mov $0x1,%edx 64.29 lock cmpxchg %edx,(%rdi) test %eax,%eax ↓ jne 2b mov %rbx,%rax pop %rbx ← retq 2b: mov %eax,%esi → callq queued_spin_lock_slowpath mov %rbx,%rax pop %rbx ← retq # Cc: Adrian Hunter <[email protected]> Cc: Andi Kleen <[email protected]> Cc: David Ahern <[email protected]> Cc: Jin Yao <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Wang Nan <[email protected]> Link: https://lkml.kernel.org/n/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>

2018-03-21ktest: Add CONNECT_TIMEOUT to change the connection timeout timeSteven Rostedt (VMware)2-2/+12
Before ktest issues a reboot, it will try to connect to the target machine to make sure that it is still alive. If the target does not respond within 5 seconds, it will power cycle the box instead of issuing a reboot. Five seconds may be too short, and ktest may unnecessarially power cycle the box. I have found 25 seconds seems to be a better timeout for this purpose. But even 25 may be too arbitrary. Add a CONNECT_TIMEOUT option to let the user determine the timeout time before rebooting. By default, it has been raised to 25 seconds. Signed-off-by: Steven Rostedt (VMware) <[email protected]>

This is not useful only for the TUI, we'll want to somehow mark the --stdio2 lines with the most jump sources too. And moving this will allow us to change some function signatures from annotate_browser to ui_browser, reducing boilerplate.

2018-03-20perf annotate: Stop using a global config structArnaldo Carvalho de Melo2-34/+51
For the TUI, that is interactive, its interesting to have a configuration that one can go on changing and then when moving from one symbol annotation to another symbol, the options set while browsing the first symbol to be kept. But since we're trying to make this code reusable by a --stdio formatter, we better have a pointer in struct annotation and in the TUI case set it to the global, but use something else for other cases, such as --stdio2.

2018-03-20perf annotate tui: Move have_cycles to struct annotationArnaldo Carvalho de Melo2-11/+15
This is to pave the way to have more functions shared between TUI, stdio and the upcoming stdio2 formatting, that will use the __scnprintf functions used by --tui in a --stdio fashion. This partially addresses the comments added in cset 30e863bb6f70 ("perf annotate: Compute IPC and basic block cycles"): /* * This should probably be in util/annotate.c to share with the tty * annotate, but right now we need the per byte offsets arrays, * which are only here. */ The following patches will address the rest.

2018-03-20test_firmware: modify custom fallback tests to use unique filesLuis R. Rodriguez3-8/+46
Users of the custom firmware fallback interface is are not supposed to use the firmware cache interface, this can happen if for instance the one of the APIs which use the firmware cache is used first with one firmware file and then the request_firmware_nowait(uevent=false) API is used with the same file. We'll soon become strict about this on the firmware interface to reject such calls later, so correct the test scripts to avoid such uses as well. We address this on the tests scripts by simply using unique names when testing the custom fallback interface. Signed-off-by: Luis R.

2018-03-20test_firmware: test three firmware kernel configs using a proc knobLuis R. Rodriguez3-1/+122
Since we now have knobs to twiddle what used to be set on kernel configurations we can build one base kernel configuration and modify behaviour to mimic such kernel configurations to test them. Provided you build a kernel with: CONFIG_TEST_FIRMWARE=y CONFIG_FW_LOADER=y CONFIG_FW_LOADER_USER_HELPER=y CONFIG_IKCONFIG=y CONFIG_IKCONFIG_PROC=y We should now be able test all possible kernel configurations when FW_LOADER=y. Note that when FW_LOADER=m we just don't provide the built-in functionality of the built-in firmware. If you're on an old kernel and either don't have /proc/config.gz (CONFIG_IKCONFIG_PROC) or haven't enabled CONFIG_FW_LOADER_USER_HELPER we cannot run these dynamic tests, so just run both scripts just as we used to before making blunt assumptions about your setup and requirements exactly as we did before.
