Dear RT folks! I'm pleased to announce the v5.10-rc5-rt11 patch set. Changes since v5.10-rc5-rt10: - The workaround for the IMX clock driver failure has been replaced with a another patch which was proposed upstream. - Tweak the rtmutex patches to build a allnoconfig with RT enabled. Known issues - It has been pointed out that due to changes to the printk code the internal buffer representation changed. This is only an issue if tools like `crash' are used to extract the printk buffer from a kernel memory image. The delta patch against v5.10-rc5-rt10 is appended below and can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/incr/patch-5.10-rc5-rt10-rt11.patch.xz You can get this release via the git tree at: git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v5.10-rc5-rt11 The RT patch against v5.10-rc5 can be found here: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patch-5.10-rc5-rt11.patch.xz The split quilt queue is available at: https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patches-5.10-rc5-rt11.tar.xz Sebastian diff --git a/drivers/clk/imx/Kconfig b/drivers/clk/imx/Kconfig index 3b393cb072951..dbacdd70af2e1 100644 --- a/drivers/clk/imx/Kconfig +++ b/drivers/clk/imx/Kconfig @@ -5,7 +5,7 @@ config MXC_CLK depends on ARCH_MXC || COMPILE_TEST config MXC_CLK_SCU - tristate "IMX SCU clock" + tristate depends on ARCH_MXC || COMPILE_TEST depends on IMX_SCU && HAVE_ARM_SMCCC diff --git a/drivers/clk/imx/Makefile b/drivers/clk/imx/Makefile index b8bf9460c91d7..dd6a737d060b4 100644 --- a/drivers/clk/imx/Makefile +++ b/drivers/clk/imx/Makefile @@ -26,9 +26,9 @@ obj-$(CONFIG_CLK_IMX8MN) += clk-imx8mn.o obj-$(CONFIG_CLK_IMX8MP) += clk-imx8mp.o obj-$(CONFIG_CLK_IMX8MQ) += clk-imx8mq.o -obj-$(CONFIG_MXC_CLK_SCU) += clk-imx-scu.o -clk-imx-scu-y := clk-scu.o clk-lpcg-scu.o -obj-$(CONFIG_CLK_IMX8QXP) += clk-imx8qxp.o clk-imx8qxp-lpcg.o +obj-$(CONFIG_MXC_CLK_SCU) += clk-imx-scu.o clk-imx-lpcg-scu.o +clk-imx-scu-$(CONFIG_CLK_IMX8QXP) += clk-scu.o clk-imx8qxp.o +clk-imx-lpcg-scu-$(CONFIG_CLK_IMX8QXP) += clk-lpcg-scu.o clk-imx8qxp-lpcg.o obj-$(CONFIG_CLK_IMX1) += clk-imx1.o obj-$(CONFIG_CLK_IMX25) += clk-imx25.o diff --git a/drivers/clk/imx/clk-lpcg-scu.c b/drivers/clk/imx/clk-lpcg-scu.c index 336dce43da82d..1f0e44f921aee 100644 --- a/drivers/clk/imx/clk-lpcg-scu.c +++ b/drivers/clk/imx/clk-lpcg-scu.c @@ -115,4 +115,3 @@ struct clk_hw *imx_clk_lpcg_scu(const char *name, const char *parent_name, return hw; } -EXPORT_SYMBOL_GPL(imx_clk_lpcg_scu); diff --git a/drivers/clk/imx/clk-scu.c b/drivers/clk/imx/clk-scu.c index 026a33606ae53..b8b2072742a56 100644 --- a/drivers/clk/imx/clk-scu.c +++ b/drivers/clk/imx/clk-scu.c @@ -9,7 +9,6 @@ #include <linux/clk-provider.h> #include <linux/err.h> #include <linux/slab.h> -#include <linux/module.h> #include "clk-scu.h" @@ -133,7 +132,6 @@ int imx_clk_scu_init(void) { return imx_scu_get_handle(&ccm_ipc_handle); } -EXPORT_SYMBOL_GPL(imx_clk_scu_init); /* * clk_scu_recalc_rate - Get clock rate for a SCU clock @@ -389,5 +387,3 @@ struct clk_hw *__imx_clk_scu(const char *name, const char * const *parents, return hw; } -EXPORT_SYMBOL_GPL(__imx_clk_scu); -MODULE_LICENSE("GPL"); diff --git a/include/linux/spinlock_types_up.h b/include/linux/spinlock_types_up.h index b0243ba07fb78..d9b371fa13e09 100644 --- a/include/linux/spinlock_types_up.h +++ b/include/linux/spinlock_types_up.h @@ -1,6 +1,10 @@ #ifndef __LINUX_SPINLOCK_TYPES_UP_H #define __LINUX_SPINLOCK_TYPES_UP_H +#if !defined(__LINUX_SPINLOCK_TYPES_H) && !defined(__LINUX_RT_MUTEX_H) +# error "please don't include this file directly" +#endif + /* * include/linux/spinlock_types_up.h - spinlock type definitions for UP * diff --git a/kernel/Kconfig.preempt b/kernel/Kconfig.preempt index c1203c14fee92..b5cd1e278eb58 100644 --- a/kernel/Kconfig.preempt +++ b/kernel/Kconfig.preempt @@ -65,6 +65,7 @@ config PREEMPT_RT bool "Fully Preemptible Kernel (Real-Time)" depends on EXPERT && ARCH_SUPPORTS_RT select PREEMPTION + select RT_MUTEXES help This option turns the kernel into a real-time kernel by replacing various locking primitives (spinlocks, rwlocks, etc.) with diff --git a/localversion-rt b/localversion-rt index d79dde624aaac..05c35cb580779 100644 --- a/localversion-rt +++ b/localversion-rt @@ -1 +1 @@ --rt10 +-rt11
