2022-12-14tools lib traceevent: Remove libtraceeventIan Rogers14-2299/+0
libtraceevent is now out-of-date and it is better to depend on the system version. Remove this code that is no longer depended upon by any builds. Committer notes: Removed the removed tools/lib/traceevent/ from tools/perf/MANIFEST, so that 'make perf-tar-src-pkg' works.

2021-06-24KVM: x86/mmu: Rename "nxe" role bit to "efer_nx" for macro shenanigansSean Christopherson1-2/+2
Rename "nxe" to "efer_nx" so that future macro magic can use the pattern <reg>_<bit> for all CR0, CR4, and EFER bits that included in the role. Using "efer_nx" also makes it clear that the role bit reflects EFER.NX, not the NX bit in the corresponding PTE.

2020-07-31libtraceevent: Fix build with binutils 2.35Ben Hutchings1-1/+1
In binutils 2.35, 'nm -D' changed to show symbol versions along with symbol names, with the usual @@ separator. When generating libtraceevent-dynamic-list we need just the names, so strip off the version suffix if present.

2020-07-06tools lib traceevent: Fix reporting of unknown SVM exit reasonsJan Kiszka1-1/+1
On AMD, exist code -1 is also a possible value, but we use it for terminating the list of known exit reasons. This leads to EXIT_ERR being reported for unkown ones. Fix this by using an NULL string pointer as terminal.

Replaced COPYING with a description of how the SPDX identifiers are used. Added a GPL-2.0 and LGPL-2.1 license file in the new LICENSES directory.

2020-07-06tools lib traceevent: Add builtin handler for trace_marker_rawSteven Rostedt (VMware)1-0/+41
When something is written into trace_marker_raw, it goes in as a binary. But the printk_fmt() of the event that is created (raw_data)'s format file only prints the first byte of data: print fmt: "id:%04x %08x", REC->id, (int)REC->buf[0] This is not very useful if we want to see the full data output. Implement the processing of the raw_data event like it is in the kernel.

The "kernel_stack" event handler does not depend on any trace-cmd context, it can be used aside from the application. The code is moved to libtraceevent "function" plugin.

2020-07-06tools lib traceevent: Add plugin for decoding syscalls/sys_enter_futexJulia Cartwright3-0/+139
The futex syscall is a complicated one. It supports thirteen multiplexed operations, each with different semantics and encodings for the syscalls six arguments. Manually decoding these arguments is tedious and error prone. This plugin provides symbolic names for futex operations, futex flags, and tries to be intelligent about the intent of specific arguments (for example, waking operations use 'val' as an integer count, not just an arbitrary value). It doesn't do a full decode of the FUTEX_WAKE_OP's 'val3' argument, however, this is a good starting point.

2019-12-16libtraceevent: Allow custom libdir pathSudip Mukherjee1-2/+3
When I use prefix=/usr and try to install libtraceevent in my laptop it tries to install in /usr/lib64. I am not having any folder as /usr/lib64 and also the debian policy doesnot allow installing in /usr/lib64. It should be in /usr/lib/x86_64-linux-gnu/. Quote: No package for a 64 bit architecture may install files in /usr/lib64/ or in a subdirectory of it. ref: https://www.debian.org/doc/debian-policy/ch-opersys.html Make it more flexible by allowing to mention libdir_relative while installing so that distros can mention the path according to their policy or use the default one.

2019-09-25libtraceevent: Move traceevent plugins in its own subdirectoryTzvetomir Stoyanov (VMware)12-0/+2089
All traceevent plugins code is moved to tools/lib/traceevent/plugins subdirectory. It makes traceevent implementation in trace-cmd and in kernel tree consistent. There is no changes in the way libtraceevent and plugins are compiled and installed. Committer notes: Applied fixup provided by Steven, fixing the tools/perf/Makefile.perf target for the plugin dynamic list file. Problem noticed when cross building to aarch64 from a Ubuntu 19.04 container.
