Abstract
Examples described herein relate to booting a processor by: reading, by a communication circuitry of the processor, boot firmware from a boot firmware storage device; executing, by the communication circuitry, the boot firmware; after the communication circuitry loads and executes the boot firmware, circuitry of the processor utilizing the communication circuitry to load boot firmware by streaming boot firmware from a second boot firmware storage device; and executing, by the circuitry of the processor, the streamed boot firmware.
Claims20
An apparatus comprising:
- a first processor comprising:
- first circuitry and second circuitry, wherein:
- the first circuitry is to load first boot firmware for execution by the first circuitry,
- based on execution of the first boot firmware by the first circuitry, the first circuitry is to provide the second circuitry with access to streamed second boot firmware, and
- the second circuitry is to request the first circuitry to stream second boot firmware for execution by the second circuitry.
A method comprising:
- booting a processor by:
- reading, by a communication circuitry of the processor, boot firmware from a boot firmware storage device;
- executing, by the communication circuitry, the boot firmware;
- after the communication circuitry loads and executes the boot firmware, circuitry of the processor utilizing the communication circuitry to load boot firmware by streaming boot firmware from a second boot firmware storage device;
- and
- executing, by the circuitry of the processor, the streamed boot firmware.
At least one non-transitory computer-readable medium comprising instructions stored thereon, that when executed by one or more circuitry, cause the one or more circuitry to:
- boot a processor by:
- read, by a communication circuitry of the processor, boot firmware from a boot firmware storage device and
- based on the communication circuitry loading and executing the boot firmware, circuitry of the processor utilizing the communication circuitry to load boot firmware by streaming boot firmware from a second boot firmware storage device.
