Hi all, There's not much improvements this week. I've been working on research how to properly save and restore userspace windows. It seems that I need to make userspace window traps preemptible. However, it will be best to have very fast, non-preemptible handler when it's possible (eg. when the stack is mapped on the MMU) and fall back to preemptible one when page fault will occur. I'm now working together with Jakub J. to solve that problem.
Other things done: * many uspace/lib/c/arch/sparc32 fixes and improvements. * fixed bug in userspace context_set() * started working on kernel timer driver Things to do next week: * Implement clever solution for userspace window trap handlers Regards, Jakub _______________________________________________ HelenOS-devel mailing list [email protected] http://lists.modry.cz/listinfo/helenos-devel
