* [SCSI] advansys: Sort out irq number messMatthew Wilcox2007-10-121-198/+189
| | | | | | | | | | | | | | | | | | | The interrupt number was being stored in 4-5 different places, each with its own type, rules and usage. Fix this by keeping an unsigned int in the struct asc_board, and filling it in from the bus probe functions (since it's different for each of the four bus types). In order to do this, we have to allocate the Scsi_Host in the bus probe functions too. Then we can return an error from advansys_board_found, which requires a little rearranging of code (and removing of the err_code variable). Move the Wide Board flag setting into the PCI bus probe function. Split the AscGetChipIRQ function into three functions (one for each bus type that needs it) and add some commentary to explain what's going on. Also get rid of the AscSetChipIRQ function as we only ever set the interrupt number to the same value it already had.

* [SCSI] advansys: Fix simultaneous calls to ->queuecommandMatthew Wilcox2007-10-121-49/+39
| | | | | | | | | | | | | The narrow board used two global structures to set up a command; unfortunately they weren't locked, so with two boards in the machine, one call to queuecommand could corrupt the data being used by the other call to queuecommand. Fix this by allocating asc_scsi_q on the stack (64 bytes) and using kmalloc for the asc_sg_head (2k) Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | The wide and narrow boards share identical handling of the return value, except for some trivial error messages. Move the handling to the common end of the function.

* [SCSI] Get rid of scsi_cmnd->doneMatthew Wilcox2007-10-129-58/+43
| | | | | | | | | | | | | | | The ULD ->done callback moves into the scsi_driver. By moving the call to scsi_io_completion() from scsi_blk_pc_done() to scsi_finish_command(), we can eliminate the latter entirely. By returning 'good_bytes' from the ->done callback (rather than invoking scsi_io_completion()), we can stop exporting scsi_io_completion(). Also move the prototypes from sd.h to sd.c as they're all internal anyway. Rename sd_rw_intr to sd_done and rw_intr to sr_done.

* [SCSI] mptlan: bug fix, only half the message frame is dma'd resulting in ↵Eric Moore2007-10-121-0/+2
| | | | | | | | | | | | | | | | | | corruption NB = number of blocks. This represents the number of blocks to transfer. The block size is based on the message frame size provided in the ioc_facts. A value of zero indicates the entire message frame should be copied. This is two bit value. So by setting this to non-zero vaule, you increase performance by reducing amount of data needing to be dma'd. The value that is stored in ioc->ReqeustNB is sometimes a non-zero vaule, which creates a bug in mptlan, where not the entire message frame is getting transfer to firware, resulting in corruption. This fix sets the default to zero, thus entire message frame is copied. Signed-off-by: Eric Moore <Eric.Moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Both callers already expect it to put the host for them, so that works out nicely. While the zalon driver does 'use' the host pointer afterwards, it only compares it for equality and doesn't dereference it, so that's safe. While I'm at it, get rid of pointless checks for NULL, use shost_priv() and change ncr53c8xx_release to return void.

This didn't matter too much when sg could only attach 256 nodes, but now the maximum has been bumped up to 32k we're starting to push the limits of the maximum allocatable contiguous memory.
