The program host
The call host: a program that loads one module and executes the isolated calls of its exports (property 19, package isolated).
The caller starts one call host per module, with two grants: the call ring and the call region. The call host has no other handle, so the module can reach nothing else (property 2). A fault in the module stops this program only.
| Fact | Value |
|---|---|
| Source | programs/host |
| Boot image | in the boot image; the image is not built, so its size is not known |
| Imports | none |
| Imported by | none |
Exports
| Export | What it does |
|---|---|
| entry() |
Read from the source of the module, as the build reads it to describe the exports (tools/kerneltool/describe.odin).
What the root service gives it
| What | Value | As the root service says |
|---|---|---|
| Grants | {} | Not named in grants_of: the grants of each other program. |
| Budget: pages, programs, threads | {pages = 2048, programs = 1, threads = 1} | Not named in things_of: the budget of each other program. |
Read from grants_of and things_of in programs/root/main.odin; budget_of in the same file adds the limits of processor time and of log records.
