From: Ben Cressey <bcressey@amazon.com> The commit "minios: refactor xenbus state machine" caused "/state" to be appended to the local value of nodename. Previously the nodename variable pointed to dev->nodename. The xenbus_rm() calls were not updated to reflect this change, and refer to paths that do not exist. For example, shutdown_blkfront() for vbd 2049 would

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than

Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,

Hello, Sometimes the backend of PVFB knows that it doesn''t need permanent refresh, when the window is minimized for instance (no refresh at all), or the administration tools know that the window is thumnailed, and so a slow refresh rate is fine. Also, some users may want to tune the refresh rate according to the smoothness they would like, balanced with the CPU time that requires.

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -
