* [SCSI] mpt3sas: Added a driver module parameter max_msix_vectorsSreekanth Reddy2013-09-031-0/+14
| | | | | | | | | | | | | | | | | | Added a driver module parameter max_msix_vectors. Using this module parameter the maximum number of MSI-X vectors could be set. The number of MSI-X vectors used would be the minimum of MSI-X vectors supported by the HBA, the number of CPU cores and the value set to max_msix_vectors module parameter. The default value of this module parameter is set to 8. The default value of this parameter is set to 8 inorder to reduce the amount of memory required for Reply Descriptor Post queue. This is because with the higher MSI-X vectors, some times kernel is not able to allocate the requested amount of memory and crash is observed. To overcome this problem, the default value is set to 8.

* [SCSI] mpt2sas: Fix for kernel panic when driver loads with HBA connected to ↵Sreekanth Reddy2013-09-031-0/+14
| | | | | | | | | | | | | | | | | | | | non LUN 0 configured expander With some enclosures when LUN 0 is not created but LUN 1 or LUN X is created then SCSI scan procedure calls target_alloc, slave_alloc call back functions for LUN 0 and slave_destory() for same LUN 0. In these kind of cases within slave_destroy, pointer to scsi_target in _sas_device structure is set to NULL, following which when slave_alloc for LUN 1 is called then starget would not be set properly for this LUN. So, scsi_target pointer pointing to NULL value would lead to a crash later in the discovery procedure. To solve this issue set the sas_device's scsi_target pointer to scsi_device's scsi_target if it is NULL earlier in slave_alloc callback function.

| | | | | | | | | | | | | | | | are removed but their transport layer entries are not removed When Async scanning mode is enabled and device scanning is in progress then devices should not be removed. But in actuality, devices are removed but their transport layer entries are not removed. This causes error to add the same device to the transport layer after host reset or diagnostic reset. So, in this patch, modified the code in such a way that device is not removed when Async scanning mode is enabled and device scanning is in progress.

* [SCSI] hpsa: fix a race in cmd_free/scsi_doneTomas Henzl2013-08-261-2/+2
| | | | | | | | | | | | When the driver calls scsi_done and after that frees it's internal preallocated memory it can happen that a new job is enqueud before the memory is freed. The allocation fails and the message "cmd_alloc returned NULL" is shown. Patch below fixes it by moving cmd->scsi_done after cmd_free.

* [SCSI] ufs: don't stop controller before scsi_remove_host()Akinobu Mita2013-08-261-1/+1
| | | | | | | | | | scsi_remove_host() sends SYNCHRONIZE CACHE commands for write cache enabled scsi disk devices. So stopping controller working shouldn't be done before scsi_remove_host().

* [SCSI] ufs: don't disable_irq() if the IRQ can be shared among devicesAkinobu Mita2013-08-262-4/+0
| | | | | | | | | | | When removing the UFS driver, disable_irq() is called and the IRQ is not enabled again. Unfortunately, the IRQ is requested with IRQF_SHARED and it can be shared among several devices. So disabling the IRQ in this way is just breaking other devices which are sharing the IRQ.

* [SCSI] ufshcd-pci: release ioremapped region during removing driverAkinobu Mita2013-08-261-28/+9
| | | | | | | | | | | | | | | | | Before commit 2953f850c3b80bdca004967c83733365d8aa0aa2 ("[SCSI] ufs: use devres functions for ufshcd"), UFSHCI register was ioremapped by each glue-driver (ufshcd-pltfrm and ufshcd-pci) during probing and it was iounmapped by core-driver during removing driver. The commit converted ufshcd-pltfrm to use devres functions, but it didn't convert ufshcd-pci. Therefore, the change causes ufshcd-pci driver not to iounmap UFSHCI register region during removing driver. This fixes it by converting ufshcd-pci to use devres functions.

Enable runtime PM by default for pci and platform drivers as the initialized hardware can suspend if it is not used after bootup.
