However, the source of time is different for both parameters: "busy_time" is assigned from "jiffies" thus has different accuracy from "total_time" which is assigned from ktime_get(). In addition, the time of window boundary is not exactly the same as the starting busy time in this window if UFS is actually busy in the beginning of the window. A similar accuracy error may also happen for the end of busy time in current window. To guarantee the precision of load calculation, we need to 1. Align time accuracy of both devfreq_dev_status.total_time and devfreq_dev_status.busy_time. For example, use "ktime_get()" directly. 2. Align the following timelines: - The beginning time of devfreq windows - The beginning of busy time in a new window - The end of busy time in the current window Link: https://lore.kernel.org/r/20200611101043.6379-1-stanley.chu@mediatek.com Fixes: a3cd5ec55f6c ("scsi: ufs: add load based scaling of UFS gear") Reviewed-by: Avri Altman Signed-off-by: Stanley Chu Signed-off-by: Martin K.

The two routines are able to handle data transfer to/from such a page in fragments and flush the cache after each fragment was copied by calling the wrapper tcmu_flush_dcache_range(). That means: 1) flush_dcache_page() can be called multiple times for the same page. 2) Calling flush_dcache_page() indirectly using the wrapper does not make sense, because each call of the wrapper is for one single page only and the calling routine already has the correct page pointer. Change (scatter|gather)_data_area() such that, instead of calling tcmu_flush_dcache_range() before/after each memcpy, it now calls flush_dcache_page() before unmapping a page (when writing is complete for that page) or after mapping a page (when starting to read the page). After this change only calls to tcmu_flush_dcache_range() for addresses in vmalloc'ed command ring are left over.

The failing NVMe array supports concurrent FCP and NVMe operation via different nport_id's. The array was repeatedly sending an ADISC every 2 seconds after PLOGI completed and while NVMe subsystems were executing discovery. The target would continue this state for roughly 45 seconds. The driver's current behavior on ADISC receipt is to validate a the ADISC vs the device and issue a RESUME_RPI to restore transmission. The receipt of the ADISC effectively caused a driver to take actions similar to a logout and login for the remote port, causing the deregistration of the nvme rport and a subsequent re-registration. This caused a constant reset and re-connect of the NVMe controller while this 45s window occurred. There was no need for the state changes as ADISC does not change login state. This patch corrects this behavior by validating if the remoteport is already logged in (MAPPED) and when true, avoids the call to set the ndlp state to MAPPED, which triggers the unreg/re-reg. Thus ADISC does not change the login state of the node.

When there is only one CPU active on the kdump kernel, it is possible for the work_on to get scheduled on a non-active CPU causing it to never be scheduled. When in the kdump environment, per-CPU affinity of cq's to cpus is not necessary. In those cases, use a general queue_work rather than a queue_work_on().

Other tasks in the system can delay handling. Change the lower level to use irq_poll by default which uses a softirq for I/O completion. This gives better latency as variance in when the cq is processed is reduced over the workqueue interface. However, as high load is better served by not being in softirq when the CPU is loaded, work queues are still used under high I/O load.

This was mainly by design to not clutter the kernel log messages with things that were typically not interesting and the messages themselves could cause other issues. When looking to make a better system, it was seen that in many cases when more data was wanted was when another message, usually at KERN_ERR level, was logged. And in most cases, what the additional logging that was then enabled was typically. Most of these areas fell into the discovery machine. Based on this summary, the following design has been put in place: The driver will maintain an internal log (256 elements of 256 bytes). The "additional logging" messages that are usually enabled in a reproduction will be changed to now log all the time to the internal log. A new logging level is defined - LOG_TRACE_EVENT. When this level is set (it is not by default) and a message marked as KERN_ERR is logged, all the messages in the internal log will be dumped to the kernel log before the KERN_ERR message is logged. There is a timestamp on each message added to the internal log. However, this timestamp is not converted to wall time when logged. The value of the timestamp is solely to give a crude time reference for the messages.

There's a theoretical race where zfcp_qdio_int_req() completes a number of SBALs & increments the queue's free-level _before_ zfcp_qdio_send() was able to decrement it. This can cause ->req_q_free to momentarily hold a value larger than QDIO_MAX_BUFFERS_PER_Q. Luckily zfcp_qdio_send() is always called under ->req_q_lock, and all readers of the free-level also take this lock. So we can trust that zfcp_qdio_send() will clean up such a temporary overflow before anyone can actually observe it. But it's still confusing and annoying to worry about. So adjust the code to avoid this race.

Many existing inline crypto devices require some additional behaviour not specified in the UFSHCI v2.1 specification - as such the vendor specific drivers will need to be updated where necessary to make it possible to use those devices. Some of these changes have already been proposed upstream, such as for the Qualcomm 845 SoC at https://lkml.kernel.org/linux-scsi/20200501045111.665881-1-ebiggers@kernel.org/ and for ufs-mediatek at https://lkml.kernel.org/linux-scsi/20200304022101.14165-1-stanley.chu@mediatek.com/ This patch has been tested on the db845c, sm8150-mtp and sm8250-mtp (which have Qualcomm chipsets) and on some mediatek chipsets using these aforementioned vendor specific driver updates.

CPUs. The driver is currently assuming exclusivity and vectors being doled out to different CPUs and is assigning primary ownership of each vector to the first CPU in the mask. The code doesn't bother to check if the CPU already owns a vector and will unconditionally overwrite the CPU to vector mapping. This causes the relationships between eq's and cq's to get confused and gets worse when CPUs start to offline. The net results are interrupts are skipped resulting in mailbox timeouts and there are oopses in CPU offling flows. Fix this changing up the primary vector assignment. Now assign the eq to a CPU only if it is the CPU in the mask that does not have a prior assignment. And once the primary ownership is assigned, break from the loop. For CPUs that may have been set before but not the primary owner, the lpfc_cpu_affinity_check() routine will balance the CPU to eq assignment.

Normally this unique tag will be in the range [0, max queue], where "max queue" is the depth of each of the submission queues. Add support for this hostwide tag feature, via module parameter "host_max_queue". A non-zero value means that the feature is enabled. In this case, the submission queues are not exposed to upper layer, i.e. from blk-mq prespective, the device has a single hw queue. There are 2 reasons for this: a. It is assumed that the host can support nr_hw_queues * can_queue commands, but this is not true for hostwide tags b. For nr_hw_queues != 0, the request tag is not unique over all HW queues, and some HBA drivers want to use this tag for the hostwide tag However, like many SCSI HBA drivers today - megaraid sas being an example - the full set of HW submission queues are still used in the LLDD driver. So instead of using a complicated "reply_map" to create a per-CPU submission queue mapping like megaraid_sas (as it depends on a PCI device + MSIs) - use a simple algorithm: hwq = cpu % queue count If the host_max_queue param is set non-zero, then the max queue depth is fixed at this value also. If and when hostwide shared tags are supported in blk-mq/scsi mid-layer, then the policy to set nr_hw_queues = 0 for hostwide tags can be revised.

Here is a list of 'opts' flags and in which cases they inject errors when abs(every_nth)%command_count == 0 is reached: - OPT_RECOVERED_ERR: issued on READ(*)s, WRITE(*)s and WRITE_SCATTEREDs - OPT_DIF_ERR: issued on READ(*)s, WRITE(*)s and WRITE_SCATTEREDs - OPT_DIX_ERR: issued on READ(*)s, WRITE(*)s and WRITE_SCATTEREDs - OPT_SHORT_TRANSFER: issued on READ(*)s - OPT_TRANSPORT_ERR: issued on all commands - OPT_CMD_ABORT: issued on all commands The other uses of every_nth were not modified. Previously if, for example, OPT_SHORT_TRANSFER was armed then if (abs(every_nth) % command_count == 0) occurred during a command that was _not_ a READ, then no error injection occurred. This behaviour puzzled several testers. Now a global "inject_pending" flag is set and the _next_ READ will get hit and that flag is cleared. OPT_RECOVERED_ERR, OPT_DIF_ERR and OPT_DIX_ERR have similar behaviour. A downside of this is that there might be a hang-over pending injection that gets triggered by a following test. Also expand the every_nth runtime parameter so that it can take hex value (i.e. with a leading '0x') as well as a decimal value. Now both the 'opts' and the 'every_nth' runtime parameters can take hexadecimal values.

The lpfc driver is currently not doing so, although it is implementing a driver internal node loss value of 30s which also is used on the SCSI FC remote port. As no devloss_tmo is set, the nvme-fc transport defaults to 60s. So there are competing timers. Additionally, due to the competing timers, it is possible the NVMe rport is removed but the SCSI rport remains. It is possible that the SCSI FC rport, which was registered for the NVMe port even if it doesn't utilize the SCSI protocol, had been tuned to not match either the 60s (nvme-fc default) or 30s (lldd default), it gets out of whack. The lldd will defer to the SCSI FC rport as long as the SCSI FC rport has not had its devloss_tmo expire. Correct the situation by specifying a default devloss_tmo to the nvme-fc transport when registering the rport. Take the value from the SCSI FC rport if it exists, otherwise use the driver default.

The standards-compliant parts, such as querying the crypto capabilities and enabling crypto for individual UFS requests, are already handled by ufshcd-crypto.c, which itself is wired into the blk-crypto framework. However, ICE requires vendor-specific init, enable, and resume logic, and it requires that keys be programmed and evicted by vendor-specific SMC calls. Make the ufs-qcom driver handle these details. I tested this on Dragonboard 845c, which is a publicly available development board that uses the Snapdragon 845 SoC and runs the upstream Linux kernel. This is the same SoC used in the Pixel 3 and Pixel 3 XL phones. This testing included (among other things) verifying that the expected ciphertext was produced, both manually using ext4 encryption and automatically using a block layer self-test I've written. I've also tested that this driver works nearly as-is on the Snapdragon 765 and Snapdragon 865 SoCs. And others have tested it on Snapdragon 850, Snapdragon 855, and Snapdragon 865 (see the Tested-by tags). This is based very loosely on the vendor-provided driver in the kernel source code for the Pixel 3, but I've greatly simplified it. Also, for now I've only included support for major version 3 of ICE, since that's all I have the hardware to test with the mainline kernel. Plus it appears that version 3 is easier to use than older versions of ICE. For now, only allow using AES-256-XTS. The hardware also declares support for AES-128-XTS, AES-{128,256}-ECB, and AES-{128,256}-CBC (BitLocker variant). But none of these others are really useful, and they'd need to be individually tested to be sure they worked properly. This commit also changes the name of the loadable module from "ufs-qcom" to "ufs_qcom", as this is necessary to compile it from multiple source files (unless we were to rename ufs-qcom.c).

However, the commit's implementation was awkward; it forced the SCSI system-resume handler to choose whether to call blk_post_runtime_resume() or blk_set_runtime_active(), depending on whether or not the SCSI device had previously been runtime suspended. This patch simplifies the situation considerably by adding the missing function call directly into blk_set_runtime_active() (under the condition that the queue is not already in the RPM_ACTIVE state). This allows the SCSI routine to revert back to its original form. Furthermore, making this change reveals that blk_post_runtime_resume() (in its success pathway) does exactly the same thing as blk_set_runtime_active(). The duplicate code is easily removed by making one routine call the other. No functional changes are intended.

Typically it's used from the interrupt handler to fetch the command associated with a value returned from hardware. Some drivers like fnic or qla4xxx, however, also use it also to traverse outstanding commands. With the current implementation scsi_host_find_tag() will return commands even if they are not started (i.e. passed to the driver). This will result in random errors with those drivers. With this patch scsi_host_find_tag() will only return 'started' commands (i.e. commands which have been passed to the drivers) thus avoiding the above issue. The other use cases will be unaffected as the interrupt handler naturally will only ever return 'started' requests.

Therefore tcmu_set_next_deadline() finds no new deadline and stops the timer, which it shouldn't. Since commands that time out are removed from inflight_queue or qfull_queue, we don't need the check with time_after() in tcmu_set_next_deadline() but can use the deadline from the first cmd in the queue. Additionally, replace the remaining time_after() calls in tcmu_check_expired_xxxxx_cmd() with time_after_eq(), because it is not useful to set the timeout to deadline but then check for jiffies being greater than deadline. Simplify the end of tcmu_handle_completions() and change the check for no more pending commands from mb->cmd_tail == mb->cmd_head to idr_is_empty(&udev->commands) because the old check doesn't work correctly if paddings or in the future TMRs are in the ring. Finally tcmu_set_next_deadline() was shifted in the source as preparation for later implementation of tmr_notify callback.

When the callback is called, tcmu checks the list of aborted commands it received as parameter: - aborted commands in the qfull_queue are removed from the queue and target_complete_command is called - from the cmd_ids of aborted commands currently uncompleted in cmd ring it creates a list of aborted cmd_ids. Finally a TMR notification is written to cmd ring containing TMR type and cmd_id list. If there is no space in ring, the TMR notification is queued on a TMR specific queue. The TMR specific queue 'tmr_queue' can be seen as a extension of the cmd ring. At the end of each iexecution of tcmu_complete_commands() we check whether tmr_queue contains TMRs and try to move them onto the ring. If tmr_queue is not empty after that, we don't call run_qfull_queue() because commands must not overtake TMRs. This way we guarantee that cmd_ids in TMR notification received by userspace either match an active, not yet completed command or are no longer valid due to userspace having complete some cmd_ids meanwhile. New commands that were assigned to an aborted cmd_id will always appear on the cmd ring _after_ the TMR.

Add the tur_ms_to_ready parameter whose unit is milliseconds (default 0) and is the period before which a TUR (or any media access command) will set the CHECK CONDITION status with a sense key of NOT READY and an additional sense of "Logical unit is in process of becoming ready". The period starts when each scsi_debug device is created. This patch was prompted by T10 proposal 20-061r2 which was accepted on 2020716. It adds that a TUR in the situation described in the previous paragraph may set the INFO field (or descriptor) in the sense data to the estimated number in milliseconds before a subsequent TUR will yield a GOOD status. This patch follows that advice. Link: https://lore.kernel.org/r/20200724155531.668144-1-dgilbert@interlog.com Reported-by: kernel test robot Signed-off-by: Douglas Gilbert Signed-off-by: Martin K.
