* scsi: pm80xx: sysfs attribute for non fatal dumpDeepak Ukey2020-03-171-0/+130
| | | | | | | | | | | | | | | | | | | Added the sysfs attribute for non fatal log so that management utility can get the non fatal dump from driver. The non-fatal error is an error condition or abnormal behavior detected by the host, or detected and reported by the controller to the host.The non-fatal error does not stop the controller firmware and enables it to still respond to host requests. A typical example of a non-fatal error is an I/O timeout or an unusual error notification from the controller. Since the firmware is operational, the error dump information is pushed to host memory (by firmware) upon request from the host.

* scsi: pm80xx: Free the tag when mpi_set_phy_profile_resp is receivedyuuzheng2020-03-171-3/+7
| | | | | | | | | | | | | | | | | | | | | In pm80xx driver, the command mpi_set_phy_profile_req is sent by host during boot to configure the phy profile such as analog setting page, rate control page. However, the tag is not freed when its response is received. As a result, 16 tags are missing for each HBA after boot. When NCQ is enabled with queue depth 16, it needs at least, 15 * 16 = 240 tags for each HBA to achieve the best performance. In current pm80xx driver with setting CCB_MAX = 256, the total number of tags in each HBA is 255 for data IO. Hence, without returning those tags to the pool after boot, some device will finally be forced to non-ncq mode by ATA layer due to excessive errors (i.e. LLDD cannot allocate tag for queued task).

* scsi: pm80xx: Deal with kexec rebootsVikram Auradkar2020-03-171-4/+11
| | | | | | | | | | | | | | | | | | | | | A kexec reboot causes the controller fw to assert. This assertion shows up in two ways, the controller doesn't show up as ready and an interrupt is waiting as soon as the handler is registered. To resolve this added below fix: - Split the interrupt handling setup into two parts, setup and request. - If the controller ready register indicates not-ready, but that the not readiness is only on the IOC units we can still try a reset to bring the system back to the pre-reboot state.

* scsi: pm80xx: Fix command issue sizingpeter chang2019-11-201-16/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | The commands to the controller are sent in fixed sized chunks which are set per-chip-generation and stashed in iomb_size. The driver fills in structs matching the register layout and memcpy this to memory shared with the controller. However, there are two problem cases: 1) Things like phy_start_req are too large because they share the sas_identify_frame definition with libsas, and it includes the crc word. This means that it's overwriting the start of the next command block, that's ok except if it happens at the end of the shared memory area. 2) Things like set_nvm_data_req which are shared between the HAL layers. This means that it's sending 'random' data for things that are in the reserved area. So far we haven't found a case where the controller FW cares, but sending possible gibberish (for most of the structures this is in the reserved area so previously zeroed) is not recommended.

* scsi: pm80xx: Convert 'long' mdelay to msleepVikram Auradkar2019-11-201-2/+2
| | | | | | | | | | | | | | | | | For delays longer than 20ms [um]delay isn't recommended. pm80xx_chip_soft_rst starts off with a 500ms delay before it even gets around to checking for the results of the reset. As long as it's at least 500ms it doesn't matter what the scheduler is doing. The delay in the pm8001_exec_internal_task_abort does nothing, and theory is this is a delay to avoid a double-free.

* [SCSI] pm80xx: Spinlock fixSuresh Thiagarajan2014-03-151-71/+13
| | | | | | | | | | | | | | | | | | spin_lock_irqsave for the HBA lock is called in one function where flag is local to that function. Another function is called from the first function where lock has to be released using spin_unlock_irqrestore for calling task_done of libsas. In the second function also flag is declared and used. For calling task_done there is no need to enable the irq. So instead of using spin_lock_irqsave and spin_unlock_irqrestore, spin_lock and spin_unlock is used now. This also avoids passing the flags across all the functions where HBA lock is being used. Also removed redundant code.
