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 ... --- include/trace/perf.h | 114 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 114 insertions(+) create mode 100644 include/trace/perf.h (limited to 'include/trace/perf.h') diff --git a/include/trace/perf.h b/include/trace/perf.h new file mode 100644 index 000000000..348ad1d9b --- /dev/null +++ b/include/trace/perf.h @@ -0,0 +1,114 @@ +/* SPDX-License-Identifier: GPL-2.0 */ + +#undef TRACE_SYSTEM_VAR + +#ifdef CONFIG_PERF_EVENTS + +#include "stages/stage6_event_callback.h" + +#undef __perf_count +#define __perf_count(c) (__count = (c)) + +#undef __perf_task +#define __perf_task(t) (__task = (t)) + +#undef __DECLARE_EVENT_CLASS +#define __DECLARE_EVENT_CLASS(call, proto, args, tstruct, assign, print) \ +static notrace void \ +do_perf_trace_##call(void *__data, proto) \ +{ \ + struct trace_event_call *event_call = __data; \ + struct trace_event_data_offsets_##call __maybe_unused __data_offsets;\ + struct trace_event_raw_##call *entry; \ + struct pt_regs *__regs; \ + u64 __count = 1; \ + struct task_struct *__task = NULL; \ + struct hlist_head *head; \ + int __entry_size; \ + int __data_size; \ + int rctx; \ + \ + __data_size = trace_event_get_offsets_##call(&__data_offsets, args); \ + \ + head = this_cpu_ptr(event_call->perf_events); \ + if (!bpf_prog_array_valid(event_call) && \ + __builtin_constant_p(!__task) && !__task && \ + hlist_empty(head)) \ + return; \ + \ + __entry_size = ALIGN(__data_size + sizeof(*entry) + sizeof(u32),\ + sizeof(u64)); \ + __entry_size -= sizeof(u32); \ + \ + entry = perf_trace_buf_alloc(__entry_size, &__regs, &rctx); \ + if (!entry) \ + return; \ + \ + perf_fetch_caller_regs(__regs); \ + \ + tstruct \ + \ + { assign; } \ + \ + perf_trace_run_bpf_submit(entry, __entry_size, rctx, \ + event_call, __count, __regs, \ + head, __task); \ +} + +/* + * Define unused __count and __task variables to use @args to pass + * arguments to do_perf_trace_##call.
