Cover letter [PATCH v3 0/3] IOCTLs in ddbridge
From: Daniel Scheller <[email protected]>
Third iteration of the IOCTL patches for ddbridge, split into multiple patches:
Patch 1 just adds the reservation/information of the used IOCTLs into ioctl-numbers.txt in the Docs dir. Doc, s390 and LKML are Cc'ed on this patch.
Patch 2 adds the header which defines the IOCTLs in include/uapi/ so userspace applications can directly reuse the IOCTL definitions by including this file.
Patch 3 (re)implements the IOCTL handling into ddbridge. This is basically code that was there since literally forever, but had to be removed along with the initial ddbridge-0.9.x bump.
The whole functionality gets more important these days since ie. the new MaxSX8 cards may require updating from time to time since these cards implement the demod/tuner communication in their FPGA (which normally I2C drivers exist for). Also, the CineS2v7 and derivatives received some important updates and the possibility to receive higher bitrate transponders these days, so users should be able to update their cards.
Changes since the last versions:
- Docs, headers and code split apart and sent out separately to the subsystems.
- Only the two absolutely necessary IOCTLs (DDB_FLASHIO and DDB_ID) are implemented for now.
