This patch series has more macro elimination and some tweaks to the DMA hooks so that all the wrapper drivers can share the same core DMA algorithm. This resolves the major discrepancies between the two core drivers, which relate to code conditional on the REAL_DMA and PSEUDO_DMA macros. After all the wrapper drivers agree on the DMA hook api, the core driver fork gets resolved. NCR5380.c is adopted by atari_scsi and sun3_scsi and atari_NCR5380.c is then deleted. Historically, the 5380 drivers suffered from over-use of conditional compilation, which caused the compile-time configuration space to explode, leading to core driver code that was practically untestable, unmaintainable and difficult to reason about. It also prevented driver modules from sharing object code. Along with REAL_DMA, REAL_DMA_POLL and PSEUDO_DMA, most of the remaining macros are also eradicated, such as CONFIG_SCSI_GENERIC_NCR53C400, SUPPORT_TAGS, DONT_USE_INTR, AUTOPROBE_IRQ and BIOSPARAM. Also in this patch series, some duplicated documentation is removed and the PDMA implementation in mac_scsi finally gets fixed. This patch series was tested by exercising the dmx3191d and mac_scsi modules on suitable hardware. Help with driver testing on ISA and Atari hardware is sought as I don't have any (likewise RiscPC ecards and Sun 3 hardware). --- Documentation/scsi/g_NCR5380.txt | 17 Documentation/scsi/scsi-parameters.txt | 11 drivers/scsi/Kconfig | 11 drivers/scsi/NCR5380.c | 661 ++++---- drivers/scsi/NCR5380.h | 145 - drivers/scsi/arm/cumana_1.c | 25 drivers/scsi/arm/oak.c | 22 drivers/scsi/atari_NCR5380.c | 2676 --------------------------------- drivers/scsi/atari_scsi.c | 142 - drivers/scsi/dmx3191d.c | 10 drivers/scsi/dtc.c | 27 drivers/scsi/dtc.h | 7 drivers/scsi/g_NCR5380.c | 143 - drivers/scsi/g_NCR5380.h | 26 drivers/scsi/mac_scsi.c | 239 +- drivers/scsi/pas16.c | 27 drivers/scsi/pas16.h | 5 drivers/scsi/sun3_scsi.c | 48 drivers/scsi/t128.c | 19 drivers/scsi/t128.h | 7 20 files changed, 636 insertions(+), 3632 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
