[edk2-devel] [PATCH 0/3] CloudHv:arm: Enable direct kernel boot
Posted by Jianyong Wu 1 week, 5 days ago
Direct kernel boot removes the dependency of retrieving kernel image
from block device. For Cloud Hypervisor, we use the following way to
support it.

1. Cloud Hypervisor store kernel image into memory and put kernel info,
   including the memory base and size, into DT;
2. When init memory in edk2, the kernel memory region is retrieved from
   DT and set it as read only memory region;
3. Edk2 fetches kernel from memory and prepare a image handle;
4. Load kernel using LoadImage in the end.

1 is done in Cloud Hypervisor, 2 and 3 is done in this patch set, 4 is
not affected.
