Dynamic memory layouts for firmware updates based on oem memory subsystem

A computing system comprising:

• one or more processors;
• system memory;
• a separate memory subsystem;
• an operating system;
• and
• firmware that is configured to perform the following:
• during a boot process, detect that the operating system has stored a capsule in the system memory, the capsule containing a firmware update;
• in response to the detection, identify a block of memory in the separate memory subsystem;
• and
• cause the capsule to be coalesced from the system memory into the block of memory in the separate memory subsystem.

One or more computer storage media storing computer executable which when executed on a computing system implement a method for providing a firmware update in the form of a capsule, the method comprising:

• during an initialization stage of a boot process, detecting that an operating system on the computing system has stored a capsule in system memory, the capsule including a firmware update;
• in response to the detection, determining that a first separate memory subsystem is to be employed to coalesce the capsule;
• identifying a block of memory in the first separate memory subsystem;
• causing the capsule to be coalesced from the system memory into the block of memory in the first separate memory subsystem;
• and
• after the capsule is coalesced into the block of memory in the first separate memory subsystem, causing the coalesced capsule to be copied into the system memory.
