From cf9610f9116d55c5a66ef9f1faecacabd93a9322 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Mon, 24 Aug 2026 08:46:03 -0700 Subject: Merge tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "Core changes: - Use the non-blocking mux_state_try_select() in the generic MUX pin control back-end - Free pin maps on pinctrl_generic_to_map() failure in the core helpers New hardware pin control: - Qualcomm Maili TLMM SoC, PMG1110 PMIC, and Eliza LPASS LPI TLMM SoC (this is for the low power audio, LPASS = Low Power Audio SubSystem portions) - Upboard support on top of the Intel pin controller - Apple T6030 and T6031 support (just compatible strings) - Samsung Exynos 8855 SoC - Mediatek MT6858 SoC - Rockchip RK3308B and RV1106 SoCs - Airoha EN7523 and AN7563 SoCs Improvements: - Qualcomm TLMM GPIOs are unconditionally marked as wakeup capable - Qualcomm improvements on top of the Qualcomm PDC (power domain controller) irqchip improvements from tglx:s tree - Qualcomm IPQ806x and IPQ9650 non-urgent pin grop fixups - The NPCM8xx driver has been put into shape fixing many pin and group definitions - Some non-urgent Tegra 264 pin assignments are fixed up - Some non-urgent fixups to Airoha AN7581 and AN7583 registers and pin assignments, missing features etc" * tag 'pinctrl-v7.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (130 commits) dt-bindings: pinctrl: Convert TI DA850 pupd to DT schema pinctrl: meson: sync some modify from A4 pinctrl: meson: a4: Add input enable pin configuration pinctrl: realtek: rtd1625: remove unused group name spdif_sel pinctrl: realtek: rtd1625: fix base_bit for VE4 GPIO 13 dt-bindings: pinctrl: microchip,pic32mzda-pinctrl: Convert to DT schema Revert "Merge branch 'ib-rsk7204' into devel" pinctrl: rockchip: Add RV1106 pinctrl support dt-bindings: pinctrl: rockchip: Add RV1106 compatible pinctrl: rockchip: Decode drive strength in the get function pinctrl: fix PINCTRL_GENERIC_MUX not always being selectable pinctrl: airoha: add support of an7563 SoC dt-bindings: pinctrl: airoha: add support of an7563 pin controller pinctrl: airoha: try to find chip scu node by phandle first pinctrl: airoha: add support of en7523 SoC dt-bindings: pinctrl: airoha: add support of en7523 pin controller pinctrl: airoha: an7583: add support for olt pinmux pinctrl: airoha: an7583: add support for pon_alt pinmux pinctrl: airoha: an7583: add support for npu_uart pinmux dt-bindings: pinctrl: airoha: an7583: add missed features ... --- tools/perf/util/libdw.h | 58 +++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 tools/perf/util/libdw.h (limited to 'tools/perf/util/libdw.h') diff --git a/tools/perf/util/libdw.h b/tools/perf/util/libdw.h new file mode 100644 index 000000000..b12094737 --- /dev/null +++ b/tools/perf/util/libdw.h @@ -0,0 +1,58 @@ +/* SPDX-License-Identifier: GPL-2.0 */ +#ifndef PERF_LIBDW_H +#define PERF_LIBDW_H + +#include + +struct dso; +struct inline_node; +struct symbol; + +#ifdef HAVE_LIBDW_SUPPORT +/* + * libdw__addr2line - Convert address to source location using libdw + * @addr: Address to resolve + * @file: Pointer to return filename (caller must free) + * @line_nr: Pointer to return line number + * @dso: The dso struct + * @unwind_inlines: Whether to unwind inline function calls + * @node: Inline node list to append to + * @sym: The symbol associated with the address + * + * This function initializes a Dwfl context for the DSO if not already present, + * finds the source line information for the given address, and optionally + * resolves inline function call chains. + * + * Returns 1 on success (found), 0 on failure (not found). + */ +int libdw__addr2line(u64 addr, char **file, + unsigned int *line_nr, struct dso *dso, + bool unwind_inlines, struct inline_node *node, + struct symbol *sym); + +/* + * dso__free_libdw - Free libdw resources associated with the DSO + * @dso: The dso to free resources for + * + * This function cleans up the Dwfl context used for addr2line lookups. + */ +void dso__free_libdw(struct dso *dso); + +#else /* HAVE_LIBDW_SUPPORT */ + +static inline int libdw__addr2line(u64 addr __maybe_unused, char **file __maybe_unused, + unsigned int *line_nr __maybe_unused, + struct dso *dso __maybe_unused, + bool unwind_inlines __maybe_unused, + struct inline_node *node __maybe_unused, + struct symbol *sym __maybe_unused) +{ + return 0; +} + +static inline void dso__free_libdw(struct dso *dso __maybe_unused) +{ +} +#endif /* HAVE_LIBDW_SUPPORT */ + +#endif /* PERF_LIBDW_H */ -- cgit v1.3.1
