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.

Support for cards with the Digital Devices PCI express bridge:
- Octopus PCIe Bridge
- Octopus mini PCIe Bridge
- Octopus LE
- DuoFlex S2 Octopus
- DuoFlex CT Octopus
- cineS2(v6)
- CineCTv6 and DuoFlex CT (STV0367-based)
- CineCTv7 and DuoFlex CT2/C2T2/C2T2I (Sony CXD28xx-based)
- MaxA8 series
- CineS2 V7/V7A and DuoFlex S2 V4 (ST STV0910-based)
- Max S4/8
Say Y if you own such a card and want to use it.
config DVB_DDBRIDGE_MSIENABLE
bool "Enable Message Signaled Interrupts (MSI) per default (EXPERIMENTAL)"
depends on DVB_DDBRIDGE
depends on PCI_MSI
help
Use PCI MSI (Message Signaled Interrupts) per default. Enabling this
might lead to I2C errors originating from the bridge in conjunction
with certain SATA controllers, requiring a reload of the ddbridge
module. MSI can still be disabled by passing msi=0 as option, as
this will just change the msi option default value.
If you're unsure, concerned about stability and don't want to pass
module options in case of troubles, say N.
Annotation
- Atlas domain: Driver Families / drivers/media.
- 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.
