System monitoring and debugging in a multi-core processor system
View Patent ↗A multi-core processor system includes a first resource, a first core, a second resource, and a second core. The first core runs a first operating system (OS), and the first resource is allocated to the first OS. The second core runs a second OS, and the second resource is exclusively allocated to the second OS. The first OS and the second OS are designed for running at the same time, and the second OS is configured for monitoring or debugging the first resource, the first core, or the first OS.
1. A multi-core processor system comprising:
a basic input/output system (BIOS);
a first resource;
a first core to run a first operating system (OS) to which the first resource is allocated;
a second resource; and
a second core electrically connected to the first core and to run a second operating system (OS), wherein the second resource is allocated to the second OS and dedicated to the second OS, such that the first OS is unable to access the second resource,
wherein the first OS and the second OS run simultaneously, and the second OS is configured to monitor a status of one of the first resource, the first core, and the first OS,
wherein the BIOS allocates the second resource and the second core and loads the second OS.
2. The system of claim 1 , wherein the second OS performs bug-checking on a status of one of the first resource, the first core, and the first OS.
3. The system of claim 1 , wherein the first core and the second core are homogeneous and interchangeable.
4. The system of claim 1 , wherein the first core and the second core are physically disposed at a same processor.
5. The system of claim 1 , wherein the second OS creates a dump file of one of the first resource, the first core, and the first OS.
6. The system of claim 5 , wherein the second OS sends the dump file out of the system.
7. A computer program product comprising a storage device storing computer-executable code executed by a computing device having a first resource, a first core running a first operating system (OS) to which the first resource is allocated, a second resource, and a second core electrically connected to the first core and to run a second OS to which the second resource is allocated and dedicated, the computing device to execute the computer-executable code to perform a method comprising:
allocating the second resource and the second core to the second OS, and loading the second OS by the first OS;
running the second OS by the second core; and
monitoring a status of one of the first resource, the first core, and the first OS by the second OS.
8. The computer program product of claim 7 , wherein monitoring the status comprises performing bug-checking on a status of one of the first resource, the first core, and the first OS by the second OS.
9. The computer program product of claim 7 , wherein the first core and the second core are homogeneous and interchangeable.
10. A method comprising:
running a first operating system (OS) with a first core of a multi-core processor system;
allocating and loading a second core of the multi-core processor system to a second OS, by the first OS; and
running the second OS with the second core, the first OS and the second OS running simultaneously.
11. The method of claim 10 , wherein the first core and the second core are homogeneous and interchangeable.
12. The method claim 10 , wherein allocating the second core comprises allocating a dedicated resource in the multi-core processor system by the second OS, and the first OS cannot access the dedicated resource.
