Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

ifdef CONFIG_RELOCATABLE
# We can't use PIC/PIE when handling early-boot errata parsing, as the kernel
# doesn't have a GOT setup at that point.  So instead just use medany: it's
# usually position-independent, so it should be good enough for the errata
# handling.
KBUILD_CFLAGS += -fno-pie -mcmodel=medany

Annotation

• Atlas domain: Architecture Layer / arch/riscv.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
