Intel® DAL supports sending and receiving events from other trusted applications or native services. To use events, trusted applications must define a special permission in the trusted application manifest to send/receive events. Trusted application events are sent to all instances of the same trusted application but
not to a specific trusted application instance
. In contrast, native events are sent to a specific instance of a trusted application.
The event mechanism can be utilized by Intel DAL services (e.g., timers), but to use them, event permissions have to be included when these services are implemented.
Trusted applications can also send events to host applications using the SendAnyMessage() method.
Trusted applications cannot process commands from the host and process events simultaneously.
Sending too many events will fill up the event queue, resulting in the loss of some of the messages.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
