* scsi: lpfc: Fix warning messages when NVME_TARGET_FC not definedDick Kennedy2017-10-031-0/+2
| | | | | | | | | | | | | | Warning messages when NVME_TARGET_FC not defined on ppc builds The lpfc_nvmet_replenish_context() function is only meaningful when NVME target mode enabled. Surround the function body with ifdefs for target mode enablement.

* scsi: lpfc: Fix lpfc nvme host rejecting IO with Not Ready messageDick Kennedy2017-10-031-18/+28
| | | | | | | | | | | | | | | | | | | | | | In a link bounce scenario, a condition can occur where the discovery engine swaps an ndlp structure (address change for an nport). While the swap was successfully executed by the discovery engine, the driver did not properly detect a change in the ndlp bound to the nvme rport. This error resulted in the nvme host transport issuing an IO to the correct nvme rport, but the lpfc driver addressed a ndlp with an NLP_UNUSED status and failed the io. This resulting it it looking like there were missing namespaces and applications failed due to io errors. To fix, in lpfc_nvme_register_rport, rework the "rebind" case to break the nvme rport<->ndlp association when the ndlp already has an nrport. Then rebind the rport to the correct ndlp data and backpointers.

* scsi: lpfc: Fix crash receiving ELS while detaching driverDick Kennedy2017-10-037-13/+37
| | | | | | | | | | | | | | | | | | | The driver crashes when attempting to use a freed ndpl pointer. The pci_remove_one handler runs on a separate kernel thread. The order of the removal is starting by freeing all of the ndlps and then disabling interrupts. In between these two events the driver can still receive an ELS and process it. When it tries to use the ndlp pointer will be NULL Change the order of the pci_remove_one vs disable interrupts so that interrupts are disabled before the ndlp's are freed.

| | | | | | | | | | | | | | | | | | | Reporting a maximum number of blocks that is not aligned on the device physical size would cause a large write same request to be split into physically unaligned chunks by __blkdev_issue_write_zeroes() and __blkdev_issue_write_same(), even if the caller of these functions took care to align its request to physical sectors. Make sure the maximum reported is aligned to the device physical block size. This is only an optional optimization for regular disks, but this is mandatory to avoid failure of large write same requests directed at sequential write required zones of host-managed ZBC disks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changing the audio sample rate on the SolidRun Cubox disrupts the video output. The Si5351 provides both the video clock (using PLLA on output 0) and the audio clock (using PLLB on output 2). When the rate of clock output 2 is changed, it reconfigures PLLB, which results in both PLLA and PLLB being reset. The reset of PLLA causes clock output 0 to be disrupted, thereby causing a loss of sync by the attached display device. Hence, each time the audio sample rate changes (eg, when a video player starts up, or when starting to play music) the video display momentarily blanks while the Si5351 settles down. Prior to the commit below, this behaviour did not happen. Fix this by only resetting only the PLL which has been changed.

However, there are multiple children clocks that could technically change the rate of audio_pll (via gck). With the rate locking, the first consumer to enable the clock will be the one definitely setting the rate of the clock. Since audio IPs are most likely to request the same rate, we enforce that the only clks able to modify gck rate are those of audio IPs. To remain consistent, we deny other clocks to be children of audio_pll.

| | | | | | | | | | | | | | | | | | | | | | | | strrchr can potentially return a null so the following strlen on the null pointer can cause a null dereference. Add a check to see if the string postfix is not null before calling strlen.

| | | | | | | | | | | | | | | | | | | | | | | | The old code uses tcxo (19.2MHz) as watchdog clock but actually the watchdog uses 32K clock, as result the watchdog timeout cannot be set correctly and delay long time to reset SoC. So this patch is to use 'ref32k' as clock source for watchdog.
