From 31cb4bd31a48f62105d037ad53192b94d4c08f53 Mon Sep 17 00:00:00 2001 From: Michael Holzheu Date: Mon, 5 Feb 2007 21:18:29 +0100 Subject: [S390] Hypervisor filesystem (s390_hypfs) for z/VM This is an extension of the already existing hypfs for LPAR (DIAG 204). Data returned by DIAG 2fc is exported using the s390_hypfs when Linux is running under z/VM. Information about cpus and memory is provided. Data is put into different virtual files which can be accessed from user space. All values are represented as ASCII strings Signed-off-by: Michael Holzheu Signed-off-by: Martin Schwidefsky --- arch/s390/hypfs/Makefile | 2 +- arch/s390/hypfs/hypfs.h | 9 ++ arch/s390/hypfs/hypfs_diag.h | 16 --- arch/s390/hypfs/hypfs_vm.c | 231 +++++++++++++++++++++++++++++++++++++++++++ arch/s390/hypfs/inode.c | 31 ++++-- 5 files changed, 262 insertions(+), 27 deletions(-) delete mode 100644 arch/s390/hypfs/hypfs_diag.h create mode 100644 arch/s390/hypfs/hypfs_vm.c (limited to 'arch/s390/hypfs') diff --git a/arch/s390/hypfs/Makefile b/arch/s390/hypfs/Makefile index f4b00cd81f7..b08d2abf617 100644 --- a/arch/s390/hypfs/Makefile +++ b/arch/s390/hypfs/Makefile @@ -4,4 +4,4 @@ obj-$(CONFIG_S390_HYPFS_FS) += s390_hypfs.o -s390_hypfs-objs := inode.o hypfs_diag.o +s390_hypfs-objs := inode.o hypfs_diag.o hypfs_vm.o diff --git a/arch/s390/hypfs/hypfs.h b/arch/s390/hypfs/hypfs.h index f3dbd91965c..aea572009d6 100644 --- a/arch/s390/hypfs/hypfs.h +++ b/arch/s390/hypfs/hypfs.h @@ -27,4 +27,13 @@ extern struct dentry *hypfs_create_str(struct super_block *sb, struct dentry *dir, const char *name, char *string);

Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.
