From: Daniel Golle Date: Thu, 30 Jul 2020 15:24:19 +0000 (+0100) Subject: kernel: clean-up build-configurable kernel config symbols X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d1a8217d87bffa33fd7d4562b3ed2f797c14beaf;p=openwrt%2Fstaging%2Fxback.git kernel: clean-up build-configurable kernel config symbols Don't explicitely disable options in target/linux/generic/config-* if they are already controlled in config/Config-kernel.in. Add a bunch of new symbols and prepare defaults for using only unified hierarchy (ie. cgroup2). Update symbol dependencies while at it Signed-off-by: Daniel Golle --- diff --git a/config/Config-kernel.in b/config/Config-kernel.in index 301d679e4e..f6464b7574 100644 --- a/config/Config-kernel.in +++ b/config/Config-kernel.in @@ -357,6 +357,18 @@ config KERNEL_BLK_DEV_BSG bool "Compile the kernel with SCSI generic v4 support for any block device" default n +config KERNEL_TRANSPARENT_HUGEPAGE + bool + +config KERNEL_HUGETLBFS + bool + +config KERNEL_HUGETLB_PAGE + bool "Compile the kernel with HugeTLB support" + select KERNEL_TRANSPARENT_HUGEPAGE + select KERNEL_HUGETLBFS + default n + config KERNEL_MAGIC_SYSRQ bool "Compile the kernel with SysRq support" default y @@ -551,21 +563,29 @@ if KERNEL_CGROUPS config KERNEL_FREEZER bool - default y if KERNEL_CGROUP_FREEZER config KERNEL_CGROUP_FREEZER - bool "Freezer cgroup subsystem" - default y + bool "legacy Freezer cgroup subsystem" + default n + select KERNEL_FREEZER help Provides a way to freeze and unfreeze all tasks in a cgroup. + (legacy cgroup1-only controller, in cgroup2 freezer + is integrated in the Memory controller) config KERNEL_CGROUP_DEVICE - bool "Device controller for cgroups" - default y + bool "legacy Device controller for cgroups" + default n help Provides a cgroup implementing whitelists for devices which a process in the cgroup can mknod or open. + (legacy cgroup1-only controller) + + config KERNEL_CGROUP_HUGETLB + bool "HugeTLB controller" + default y if KERNEL_HUGETLB_PAGE + depends on KERNEL_HUGETLB_PAGE config KERNEL_CGROUP_PIDS bool "PIDs cgroup subsystem" @@ -574,6 +594,14 @@ if KERNEL_CGROUPS Provides enforcement of process number limits in the scope of a cgroup. + config KERNEL_CGROUP_RDMA + bool "RDMA controller for cgroups" + default y + + config KERNEL_CGROUP_BPF + bool "Support for eBPF programs attached to cgroups" + default y + config KERNEL_CPUSETS bool "Cpuset support" default y if !SMALL_FLASH @@ -609,6 +637,7 @@ if KERNEL_CGROUPS config KERNEL_MEMCG bool "Memory Resource Controller for Control Groups" default y if !SMALL_FLASH + select KERNEL_FREEZER depends on KERNEL_RESOURCE_COUNTERS || !LINUX_3_18 help Provides a memory resource controller that manages both anonymous @@ -631,7 +660,7 @@ if KERNEL_CGROUPS config KERNEL_MEMCG_SWAP bool "Memory Resource Controller Swap Extension" - default n + default y if !SMALL_FLASH depends on KERNEL_MEMCG help Add swap management feature to memory resource controller.
