When a page fault cannot be resolved, the GDB monitor can get a hint about which thread faulted by evaluating the thread state object returned by 'Cpu_session::state()'. Unfortunately, with the current implementation, the signal which informs GDB monitor about the page fault is sent before the thread state object of the faulted thread has been updated, so it can happen that the faulted thread cannot be determined immediately after receiving the signal. With this commit, the thread state gets updated before the signal is sent. At least on base-nova it can also happen that the thread state is not accessible yet after receiving the page fault notification. For this reason, GDB monitor needs to retry its query until the state is accessible. Fixes #1206. |

This is generic part of the Genode implementation. It consists of two parts: :_Core_: is the ultimate root of the Genode application tree and provides abstractions for the lowest-level hardware resources such as RAM, ROM, CPU, and generic device access. All generic parts of Core can be found here - for system-specific implementations refer to the appropriate 'base-<system>' directory. :_Base libraries and protocols_: that are used by each Genode component to interact with other components. This is the glue that holds everything together.
