* rsxx: Adding in debugfs entries.Philip J Kelleher2013-06-191-0/+275
| | | | | | | | | | | | | | | | | | | Adding debugfs entries to help with debugging and testing and testing code. pci_regs: This entry will spit out all of the data stored on the BAR. stats: This entry will display all of the driver stats for each DMA channel. cram: This will allow read/write ability to the CRAM address space on our adapter's CPU.

* rsxx: Changing the adapter name to the official name.Philip J Kelleher2013-06-191-5/+5
| | | | | | | | Changing the adapter name from FlashSystem-80 to the official name: Flash Adapter 900GB Full Height. Signed-off-by: Philip J Kelleher <pjk1939@linux.vnet.ibm.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
* rsxx: Adding in sync_start module paramenter.Philip J Kelleher2013-06-191-0/+34
| | | | | | | | | | | | Before, the partition table would have to be reread because our card was attached before it transistioned out of it's 'starting' state. This change will cause the driver to wait to attach the device until the adapter is ready. Signed-off-by: Philip J Kelleher <pjk1939@linux.vnet.ibm.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
* rsxx: Restructured DMA cancel scheme.Philip J Kelleher2013-06-191-3/+14
| | | | | | | | | | | | | Before, DMAs would never be cancelled if there was a data stall or an EEH Permenant failure which would cause an unrecoverable I/O hang. The DMA cancellation mechanism has been modified to fix these issues and allows DMAs to be cancelled during the above mentioned events.

* rsxx: Individual workqueues for interruptible events.Philip J Kelleher2013-06-191-3/+20
| | | | | | | | | Giving all interrupt based events their own workqueue to complete tasks on. This fixes a bug that would cause creg commands to timeout if too many are issued at once. Signed-off-by: Philip J Kelleher <pjk1939@linux.vnet.ibm.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
* rsxx: enable error return of rsxx_eeh_save_issued_dmas()Philip J Kelleher2013-03-261-3/+16
| | | | | | | | | Commit d8d595df introduced a bug where we did not check for a NULL return from kmalloc(). Make rsxx_eeh_save_issued_dmas() return an error for that case, and make the callers handle that.
