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/bootconfig/scripts/ftrace.sh | 110 +++++++++++++++++++++++++++++++++++++ 1 file changed, 110 insertions(+) create mode 100644 tools/bootconfig/scripts/ftrace.sh (limited to 'tools/bootconfig/scripts/ftrace.sh') diff --git a/tools/bootconfig/scripts/ftrace.sh b/tools/bootconfig/scripts/ftrace.sh new file mode 100644 index 000000000..cc5250c64 --- /dev/null +++ b/tools/bootconfig/scripts/ftrace.sh @@ -0,0 +1,110 @@ +#!/bin/sh +# SPDX-License-Identifier: GPL-2.0-only + +clear_trace() { # reset trace output + echo > trace +} + +disable_tracing() { # stop trace recording + echo 0 > tracing_on +} + +enable_tracing() { # start trace recording + echo 1 > tracing_on +} + +reset_tracer() { # reset the current tracer + echo nop > current_tracer +} + +reset_trigger_file() { + # remove action triggers first + grep -H ':on[^:]*(' $@ | + while read line; do + cmd=`echo $line | cut -f2- -d: | cut -f1 -d"["` + file=`echo $line | cut -f1 -d:` + echo "!$cmd" >> $file + done + grep -Hv ^# $@ | + while read line; do + cmd=`echo $line | cut -f2- -d: | cut -f1 -d"["` + file=`echo $line | cut -f1 -d:` + echo "!$cmd" > $file + done +} + +reset_trigger() { # reset all current setting triggers + if [ -d events/synthetic ]; then + reset_trigger_file events/synthetic/*/trigger + fi + reset_trigger_file events/*/*/trigger +} + +reset_events_filter() { # reset all current setting filters + grep -v ^none events/*/*/filter | + while read line; do + echo 0 > `echo $line | cut -f1 -d:` + done +} + +reset_ftrace_filter() { # reset all triggers in set_ftrace_filter + if [ !
