Messages in this thread | | | From | Christoffer Dall <> | Subject | [C/R ARM v2][PATCH 0/3] Linux Checkpoint-Restart - ARM port | Date | Mon, 26 Apr 2010 17:43:40 -0400 |
| |
Following there will be two preparatory patches for an ARM port of the checkpoint-restart code and finally a third patch implementing the architecture-specific parts of c/r.
The preparatory patches consist of a partial syscall trace implementation for ARM and an eclone implementation for ARM. The syscall trace implementation provides only the needed functionality for c/r.
There is a separate patch for the user space code, which supports cross-compilation, extracting headers for ARM and an eclone implementation for ARM.
The kernel patches presented here are based on the ckpt-v21-rc6 patch set.

CHANGELOG:
[2010-Apr-08] v2: - Systrace implementation now inspects process state to get the system call number thereby avoiding extra work on system calls. - Removed __user attribute on long type in eclone implementation - Better check for architecture versions across C/R - Improved checking of user space ABI settings across C/R - Code simplifications
[2010-Mar-22] v1: - Initial version - Systrace implementation modified the system call entry path to store the system call number globally in memory. - ARM implementation lightly tested
