The program boot
A system tool: how the machine started, at any time. It draws the boot display (package bootscreen) in a window, with the records that the kernel has now. It needs the grant to inspect the machine, and the boot image.
| Fact | Value |
|---|---|
| Source | programs/boot |
| 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 | {.Inspect, .Image} | It shows the modules of the boot image. |
| 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.
