2016-01-06ncr5380: Add support for HP C2502Ondrej Zary1-0/+1
HP C2502 cards (based on 53C400A chips) use different magic numbers for software-based I/O address configuration than other cards. The configuration is also extended to allow setting the IRQ. Move the configuration to a new function magic_configure() and move magic the magic numbers into an array. Add new magic numbers for these HP cards and hp_c2502 module parameter to use them, e.g.: modprobe g_NCR5380 ncr_irq=7 ncr_addr=0x280 hp_c2502=1 Tested with HP C2502 and DTCT-436P.

2016-01-06ncr5380: Enable PDMA for DTC chipsOndrej Zary1-1/+2
Add I/O register mapping for DTC chips and enable PDMA mode. These chips have 16-bit wide HOST BUFFER register and it must be read by 16-bit accesses (we lose data otherwise). Large PIO transfers crash at least the DTCT-436P chip (all reads result in 0xFF) so this patch actually makes it work. The chip also crashes when we bang on the C400 host status register too heavily after PDMA write - a small udelay is needed. Tested on DTCT-436P and verified that it does not break 53C400A.

2016-01-06ncr5380: Use runtime register mappingOndrej Zary1-4/+8
Convert compile-time C400_ register mapping to runtime mapping. This removes the weird negative register offsets and allows adding additional mappings. While at it, convert read/write loops into insb/outsb.

Follow the example of the atari_NCR5380.c core driver and adopt the NCR5380_dma_xfer_len() hook. Implement NCR5380_dma_xfer_len() for dtc.c and g_NCR5380.c to take care of the limitations of these cards. Keep the default for drivers using PSEUDO_DMA.

2016-01-06ncr5380: Remove NCR5380_local_declare and NCR5380_setup macrosFinn Thain1-19/+11
The NCR5380_local_declare and NCR5380_setup macros exist to define and initialize a particular local variable, to provide the address of the chip registers needed for the driver's implementation of its NCR5380_read/write register access macros. In cumana_1 and macscsi, these macros generate pointless code like this, struct Scsi_Host *_instance; _instance = instance; In pas16, the use of NCR5380_read/write in pas16_hw_detect() requires that the io_port local variable has been defined and initialized, but the NCR5380_local_declare and NCR5380_setup macros can't be used for that purpose because the Scsi_Host struct has not yet been instantiated. Moreover, these macros were removed from atari_NCR5380.c long ago and now they constitute yet another discrepancy between the two core driver forks. Remove these "optimizations".

2014-11-20ncr5380: Cleanup host info() methodsFinn Thain1-0/+2
If the host->info() method is not set, then host->name is used by default. For atari_scsi, that is exactly the same text. So remove the redundant info() method. Keep sun3_scsi.c in line with atari_scsi. Some NCR5380 drivers return an empty string from the info() method (arm/cumana_1.c arm/oak.c mac_scsi.c) while other drivers use the default (dmx3191d dtc.c g_NCR5380.c pas16.c t128.c). Implement a common info() method to replace a lot of duplicated code which the various drivers use to announce the same information. This replaces most of the (deprecated) show_info() output and all of the NCR5380_print_info() output. This also eliminates a bunch of code in g_NCR5380 which just duplicates functionality in the core driver.

2010-11-16SCSI host lock push-downJeff Garzik1-1/+1
Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+131
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
