Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] s390_hypfs filesystem On zSeries machines there exists an interface which allows the operating system to retrieve LPAR hypervisor accounting data. For example, it is possible to get usage data for physical and virtual cpus. In order to provide this information to user space programs, I implemented a new virtual Linux file system named 's390_hypfs' using the Linux 2.6 libfs framework. The name 's390_hypfs' stands for 'S390 Hypervisor Filesystem'. All the accounting information is put into different virtual files which can be accessed from user space. All data is represented as ASCII strings. When the file system is mounted the accounting information is retrieved and a file system tree is created with the attribute files containing the cpu information. The content of the files remains unchanged until a new update is made. An update can be triggered from user space through writing 'something' into a special purpose update file. We create the following directory structure: <mount-point>/ update cpus/ <cpu-id> type mgmtime <cpu-id> ... hyp/ type systems/ <lpar-name> cpus/ <cpu-id> type mgmtime cputime onlinetime <cpu-id> ... <lpar-name> cpus/ ... - update: File to trigger update - cpus/: Directory for all physical cpus - cpus/<cpu-id>/: Directory for one physical cpu. - cpus/<cpu-id>/type: Type name of physical zSeries cpu. - cpus/<cpu-id>/mgmtime: Physical-LPAR-management time in microseconds. - hyp/: Directory for hypervisor information - hyp/type: Typ of hypervisor (currently only 'LPAR Hypervisor') - systems/: Directory for all LPARs - systems/<lpar-name>/: Directory for one LPAR. - systems/<lpar-name>/cpus/<cpu-id>/: Directory for the virtual cpus - systems/<lpar-name>/cpus/<cpu-id>/type: Typ of cpu. - systems/<lpar-name>/cpus/<cpu-id>/mgmtime: Accumulated number of microseconds during which a physical CPU was assigned to the logical cpu and the cpu time was consumed by the hypervisor and was not provided to the LPAR (LPAR overhead). - systems/<lpar-name>/cpus/<cpu-id>/cputime: Accumulated number of microseconds during which a physical CPU was assigned to the logical cpu and the cpu time was consumed by the LPAR. - systems/<lpar-name>/cpus/<cpu-id>/onlinetime: Accumulated number of microseconds during which the logical CPU has been online. As mount point for the filesystem /sys/hypervisor/s390 is created. The update process is triggered when writing 'something' into the 'update' file at the top level hypfs directory. You can do this e.g. with 'echo 1 > update'. During the update the whole directory structure is deleted and built up again.
