Why This File Exists
Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
- Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
- Touches IRQ or DMA behavior; this matters for the representative real-device path.
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.

config NTB_PINGPONG
tristate "NTB Ping Pong Test Client"
help
This is a simple ping pong driver that exercises the scratchpads and
doorbells of the ntb hardware. This driver may be used to test that
your ntb hardware and drivers are functioning at a basic level.
If unsure, say N.
config NTB_TOOL
tristate "NTB Debugging Tool Test Client"
help
This is a simple debugging driver that enables the doorbell and
scratchpad registers to be read and written from the debugfs. This
enables more complicated debugging to be scripted from user space.
This driver may be used to test that your ntb hardware and drivers are
functioning at a basic level.
If unsure, say N.
config NTB_PERF
tristate "NTB RAW Perf Measuring Tool"
help
This is a tool to measure raw NTB performance by transferring data
to and from the window without additional software interaction.
If unsure, say N.
config NTB_MSI_TEST
tristate "NTB MSI Test Client"
depends on NTB_MSI
help
This tool demonstrates the use of the NTB MSI library to
send MSI interrupts between peers.
If unsure, say N.
Annotation
- Atlas domain: Driver Families / drivers/ntb.
- Implementation status: atlas-only.
- IRQ or DMA behavior appears here, which is relevant to the selected PCIe/NVMe device path.
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.
