Hi all, After merging the arm64 tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/perf/amlogic/meson_g12_ddr_pmu.c: In function 'dmc_g12_get_freq_quick': drivers/perf/amlogic/meson_g12_ddr_pmu.c:135:15: error: implicit declaration of function 'readl' [-Werror=implicit-function-declaration] 135 | val = readl(info->pll_reg); | ^~~~~ drivers/perf/amlogic/meson_g12_ddr_pmu.c: In function 'dmc_g12_counter_enable': drivers/perf/amlogic/meson_g12_ddr_pmu.c:204:9: error: implicit declaration of function 'writel' [-Werror=implicit-function-declaration] 204 | writel(clock_count, info->ddr_reg[0] + DMC_MON_G12_TIMER); | ^~~~~~ Caused by commit 2016e2113d35 ("perf/amlogic: Add support for Amlogic meson G12 SoC DDR PMU driver") I have used the arm64 tree from next-20221121 for today. -- Cheers, Stephen Rothwell
