| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During cluster testing, one QP was not closed, as FIN is not handled properly when its rexmit count expires or in some cases when RST is is received after sending FIN. The reason is that the cm_id does not get decremented under these conditions. Signed-off-by: Faisal Latif <faisal.latif@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | * | IB/mthca: Replace dma_sync_single() use with proper functionsRoland Dreier2009-06-221-3/+10
| | | | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dma_sync_single() is deprecated now, and the use in mthca is wrong: there should be a dma_sync_single_for_cpu() before touching the memory from the CPU, and a dma_sync_single_for_device() afterwards. Fix this, prompted by a kick in the pants from a patch from FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>. Signed-off-by: Roland Dreier <rolandd@cisco.com>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement toleration of dynamic memory operations and 16 GB gigantic pages, where "toleration" means that the driver can cope with dynamic memory operations that happen before the driver is loaded. While the ehca driver is loaded, dynamic memory operations are still prohibited by returning NOTIFY_BAD from the memory notifier. On module load the driver walks through available system memory, checks for available memory ranges and then registers the kernel internal memory region accordingly. The translation of address ranges is implemented via a 3-level busmap. Signed-off-by: Hannes Hering <hering2@de.ibm.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There have been several bug reports which identified the Ultrium-3 tape as just hanging up on the bus during certain types of IU transfer. The identified culpret is type 0x02 (MULTIPLE COMMAND) transfers. The only way to prevent this tape wedging is to prevent it from using IU transfers at all.
