Earlier the System Call entry from an unprivileged task looked like: 1. SVC for entering system call. 2. System call implementation. 3. SVC for exiting system call. Now, the system call entry needs to make only one SVC call and everything else is handled internally. This PR also makes the following changes: 1. Update the Access Control List (ACL) mechanism to grant access to all the kernel objects before the scheduler is started. 2. Add one struct param for system calls with 5 parameters. This removes the need for special handling for system calls with 5 parameters. 3. Remove raise privilege SVC when MPU wrapper v2 is used. 4. Add additional run time parameter checks to MPU wrappers for xTaskGenericNotify and xQueueTakeMutexRecursive APIs. |
