From 9f0346dcbea363787186c94ef94dd01aaa215afa Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 5 Sep 2026 11:59:05 -0700 Subject: Merge tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core Pull driver core fixes from Danilo Krummrich: - Fix kernfs listxattr() not returning security xattr names (e.g. SELinux labels) when the kernfs node has no allocated kernfs_iattrs - Fix silent truncation of IRQ vector indices in the Rust PCI abstractions - Don't select OF from DRIVER_PE_KUNIT_TEST; skip the test when OF is disabled instead of silently enabling extra kernel functionality - Russ Weight is retiring from kernel development; update the Firmware Loader sysfs contact to the driver-core mailing list, add a CREDITS entry for Firmware Upload, and update MAINTAINERS accordingly * tag 'driver-core-7.3-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: MAINTAINERS: Remove Russ Weight from Firmware Loader CREDITS: Add CREDITS entry for Firmware Upload firmware_loader: Change contact for sysfs nodes rust: pci: reject IRQ vector indices that do not fit in u32 kernfs: preserve security xattrs without allocating iattrs drivers: base: test: DRIVER_PE_KUNIT_TEST should not select OF --- tools/perf/util/debuginfo.h | 66 +++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 66 insertions(+) create mode 100644 tools/perf/util/debuginfo.h (limited to 'tools/perf/util/debuginfo.h') diff --git a/tools/perf/util/debuginfo.h b/tools/perf/util/debuginfo.h new file mode 100644 index 000000000..a52d69932 --- /dev/null +++ b/tools/perf/util/debuginfo.h @@ -0,0 +1,66 @@ +/* SPDX-License-Identifier: GPL-2.0-or-later */ +#ifndef _PERF_DEBUGINFO_H +#define _PERF_DEBUGINFO_H + +#include +#include + +#ifdef HAVE_LIBDW_SUPPORT + +#include "dwarf-aux.h" + +/* debug information structure */ +struct debuginfo { + Dwarf *dbg; + Dwfl_Module *mod; + Dwfl *dwfl; + Dwarf_Addr bias; + const unsigned char *build_id; +}; + +/* This also tries to open distro debuginfo */ +struct debuginfo *debuginfo__new(const char *path); +void debuginfo__delete(struct debuginfo *dbg); + +int debuginfo__get_text_offset(struct debuginfo *dbg, Dwarf_Addr *offs, + bool adjust_offset); + +#else /* HAVE_LIBDW_SUPPORT */ + +/* dummy debug information structure */ +struct debuginfo { +}; + +static inline struct debuginfo *debuginfo__new(const char *path __maybe_unused) +{ + return NULL; +} + +static inline void debuginfo__delete(struct debuginfo *dbg __maybe_unused) +{ +} + +typedef void Dwarf_Addr; + +static inline int debuginfo__get_text_offset(struct debuginfo *dbg __maybe_unused, + Dwarf_Addr *offs __maybe_unused, + bool adjust_offset __maybe_unused) +{ + return -EINVAL; +} + +#endif /* HAVE_LIBDW_SUPPORT */ + +#ifdef HAVE_DEBUGINFOD_SUPPORT +int get_source_from_debuginfod(const char *raw_path, const char *sbuild_id, + char **new_path); +#else /* HAVE_DEBUGINFOD_SUPPORT */ +static inline int get_source_from_debuginfod(const char *raw_path __maybe_unused, + const char *sbuild_id __maybe_unused, + char **new_path __maybe_unused) +{ + return -ENOTSUP; +} +#endif /* HAVE_DEBUGINFOD_SUPPORT */ + +#endif /* _PERF_DEBUGINFO_H */ -- cgit v1.3.1
