This completes the show_sdb_tree functionality, with the new informative fields. The output for a verbose module is now like this (long lines are unavoidable): SDB: 00000651:e6a542c9 WB4-Crossbar-GSI SDB: 0000ce42:00000601 WB-DMA.Control (00001000-0000103f) SDB: 0000ce42:779c5443 WB-OneWire-Master (00001100-000011ff) SDB: 0000ce42:00000603 WB-SPEC-CSR (00001200-0000121f) SDB: 0000ce42:00000013 WB-VIC-Int.Control (00001300-000013ff) SDB: 0000ce42:d5735ab4 WB-DMA.EIC (00001400-0000140f) SDB: 00000651:eef0b198 WB4-Bridge-GSI (bridge: 00002000) SDB: 00000651:e6a542c9 WB4-Crossbar-GSI SDB: 0000ce42:123c5443 WB-I2C-Master (00003000-000030ff) SDB: 0000ce42:e503947e WB-SPI.Control (00003100-0000311f) SDB: 0000ce42:123c5443 WB-I2C-Master (00003200-000032ff) SDB: 0000ce42:00000608 WB-FMC-ADC-Core (00003300-0000337f) SDB: 0000ce42:779c5443 WB-OneWire-Master (00003400-000034ff) SDB: 0000ce42:26ec6086 WB-FMC-ADC.EIC (00003500-0000350f) SDB: 0000ce42:00000604 WB-Timetag-Core (00003600-0000367f) SDB: Synthesis repository: git://ohwr.org/fmc-projects/fmc-adc-100m14b4cha.git SDB: Bitstream 'spec_top_fmc_adcmc-projects/fmc-adc-100m14b4cha.git' \ synthesized 20140116 by mcattin (ISE version 133), commit f0a539dffe6d Signed-off-by: NTomasz Wlostowski <tomasz.wlostowski@cern.ch> Acked-by: NAlessandro Rubini <rubini@gnudd.com> Acked-by: NJuan David Gonzalez Cobas <dcobas@cern.ch> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>

This allows easier modification to the eeprom than loading the fmc-write-eeprom module. The carrier driver will refuse writing if the FPGA is not running the golden gateware image, so writing in practice is only available at manufacture/development time.

The code reported wrong addresses in the sdb dumps. All sdb addresses are relative, but the code was adding the base address twice. Bug exposed by a gateware image with two bridge levels.

At registration and unregistration time, I was checking fmc->flags for FMC_DEVICE_NO_MEZZANINE, to skip initialization and cleanup for empty slots. The check was wrong ("==" instead of "&") but registration failed anyways (as expected) because we had no EEPROM. This commit fixes one such checks and removes the other, so to actually accept slots with no mezzanines. That's because the carrier may offer some support anyways (the SPEC does), and working on the carrier with no mezzanine-specific driver is common during development.

The fmc-chardev module was over-locking, by calling misc register/unregister while holding its spinlock. This reported a "scheduling while atomic" error. Since the misc driver already serializes operations internally, this commit downgrades the fmc-chardev lock to just cover its own list.

This fake carrier is designed to help FMC users understand how a carrier driver works, and to experiment the behaviour with EEPROM reprogramming (with a mezzanine driver commited later). This carrier can register up to 4 (fake) mezzanines. We have real carriers (both on PCI-E and VME), but they are bigger things and are not part of this submission.

This module offers registration services for both carriers (i.e. devices) and mezzanines (i.e. drivers). The matching for devices and drivers is performed according to the IPMI standard for FRU devices (Field Replaceable Units). The code includes support for parsing an SDB tree if present in the FPGA, and dumping it for diagnostics. SDB is not mandatory. Files in this commit correspond to commit ab23167f in the master branch of the project hosted on ohwr.org.
