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/tests/bitmap.c | 56 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 tools/perf/tests/bitmap.c (limited to 'tools/perf/tests/bitmap.c') diff --git a/tools/perf/tests/bitmap.c b/tools/perf/tests/bitmap.c new file mode 100644 index 000000000..e7adf60be --- /dev/null +++ b/tools/perf/tests/bitmap.c @@ -0,0 +1,56 @@ +// SPDX-License-Identifier: GPL-2.0 +#include +#include +#include +#include +#include "tests.h" +#include "debug.h" + +#define NBITS 100 + +static unsigned long *get_bitmap(const char *str, int nbits) +{ + struct perf_cpu_map *map = perf_cpu_map__new(str); + unsigned long *bm; + + bm = bitmap_zalloc(nbits); + + if (map && bm) { + unsigned int i; + struct perf_cpu cpu; + + perf_cpu_map__for_each_cpu(cpu, i, map) + __set_bit(cpu.cpu, bm); + } + + perf_cpu_map__put(map); + return bm; +} + +static int test_bitmap(const char *str) +{ + unsigned long *bm = get_bitmap(str, NBITS); + char buf[100]; + int ret; + + bitmap_scnprintf(bm, NBITS, buf, sizeof(buf)); + pr_debug("bitmap: %s\n", buf); + + ret = !strcmp(buf, str); + free(bm); + return ret; +} + +static int test__bitmap_print(struct test_suite *test __maybe_unused, int subtest __maybe_unused) +{ + TEST_ASSERT_VAL("failed to convert map", test_bitmap("1")); + TEST_ASSERT_VAL("failed to convert map", test_bitmap("1,5")); + TEST_ASSERT_VAL("failed to convert map", test_bitmap("1,3,5,7,9,11,13,15,17,19,21-40")); + TEST_ASSERT_VAL("failed to convert map", test_bitmap("2-5")); + TEST_ASSERT_VAL("failed to convert map", test_bitmap("1,3-6,8-10,24,35-37")); + TEST_ASSERT_VAL("failed to convert map", test_bitmap("1,3-6,8-10,24,35-37")); + TEST_ASSERT_VAL("failed to convert map", test_bitmap("1-10,12-20,22-30,32-40")); + return 0; +} + +DEFINE_SUITE("Print bitmap", bitmap_print); -- cgit v1.3.1
