In check_fw_ready() we first wait for ILA to come up and then we wait for RAAE to come up and IOPs and so on. This is a sequential check. Because of this, ILA image seems to be not ready in the allocated time and so the driver marks it as "not ready" and then moves on to other FW images. ILA does become ready eventually, but is not checked again. The driver concludes that FW is not ready when it actually is. Instead of sequentially polling each image, we keep polling for all images to be ready. The timeout for the polling has been set to the sum of what was used for each individual image.

The function pm80xx_get_fatal_dump() has two issues that result in the fatal dump not being able to complete successfully. 1. Trying to collect fatal_logs from the application fails because we are not shifting the MEMBASE-II register properly. Once we read 64K region of data we have to shift the MEMBASE-II register and read the next chunk. Only then would we be able to get complete data. 2. If a timeout occurs, our application will get stuck. Link: https://lore.kernel.org/r/20210109123849.17098-6-Viswas.G@microchip.comAcked-by: -

The driver initializes main configuration, general status, inbound queue and outbound queue table addresses based on a value read from MSGU_SCRATCH_PAD_0 register. We should validate these addresses before dereferencing them. Adds two validations: 1. Check if main configuration table offset lies within the pcibar mapped 2. Check if first dword of main configuration table reads "PMCS" There are two calls to init_pci_device_addresses() done during pm8001_pci_probe() in this sequence: 1. First inside chip_soft_rst, where if init_pci_device_addresses fails we will go ahead assuming MPI state is not ready and reset the device as long as bootloader is okay. This gives chance to second call of init_pci_device_addresses to set up the addresses after reset. 2. The second call is via pm80xx_chip_init, after soft reset is done and firmware is checked to be ready. Once that is done we are safe to go ahead and initialize default table values and use them. Tests: 1. Enabled debugging logs and observed no issues during initialization, with a controller with no issues: pm80xx0:: pm8001_setup_msix 1034: pci_alloc_irq_vectors request ret:64 no of intr 64 pm80xx0:: init_pci_device_addresses 917: Scratchpad 0 Offset: 0x2000 value 0x40002000 pm80xx0:: init_pci_device_addresses 925: Scratchpad 0 PCI BAR: 0 pm80xx0:: init_pci_device_addresses 952: VALID main config signature 0x53434d50 pm80xx0:: init_pci_device_addresses 975: GST OFFSET 0xc4 pm80xx0:: init_pci_device_addresses 978: INBND OFFSET 0x20000128 pm80xx0:: init_pci_device_addresses 981: OBND OFFSET 0x24000928 pm80xx0:: init_pci_device_addresses 984: IVT OFFSET 0x8001408 pm80xx0:: init_pci_device_addresses 987: PSPA OFFSET 0x8001608 pm80xx0:: init_pci_device_addresses 991: addr - main cfg (ptrval) general status (ptrval) pm80xx0:: init_pci_device_addresses 995: addr - inbnd (ptrval) obnd (ptrval) pm80xx0:: init_pci_device_addresses 999: addr - pspa (ptrval) ivt (ptrval) pm80xx0:: pm80xx_chip_soft_rst 1446: reset register before write : 0x0 pm80xx0:: pm80xx_chip_soft_rst 1478: reset register after write 0x40 pm80xx0:: pm80xx_chip_soft_rst 1544: SPCv soft reset Complete pm80xx0:: init_pci_device_addresses 917: Scratchpad 0 Offset: 0x2000 value 0x40002000 pm80xx0:: init_pci_device_addresses 925: Scratchpad 0 PCI BAR: 0 pm80xx0:: init_pci_device_addresses 952: VALID main config signature 0x53434d50 pm80xx0:: init_pci_device_addresses 975: GST OFFSET 0xc4 pm80xx0:: init_pci_device_addresses 978: INBND OFFSET 0x20000128 pm80xx0:: init_pci_device_addresses 981: OBND OFFSET 0x24000928 pm80xx0:: init_pci_device_addresses 984: IVT OFFSET 0x8001408 pm80xx0:: init_pci_device_addresses 987: PSPA OFFSET 0x8001608 pm80xx0:: init_pci_device_addresses 991: addr - main cfg (ptrval) general status (ptrval) pm80xx0:: init_pci_device_addresses 995: addr - inbnd (ptrval) obnd (ptrval) pm80xx0:: init_pci_device_addresses 999: addr - pspa (ptrval) ivt (ptrval) pm80xx0:: pm80xx_chip_init 1329: MPI initialize successful! 2.

People testing have a need to know how many errors might be occurring over time. Add error counters and expose them via debugfs. A module initcall is used to create a debugfs root directory for ufshcd-related items. In the case that modules are built-in, then initialization is done in link order, so move ufshcd-core to the top of the Makefile.

Current code overestimates the value of max_outstanding_req_per_channel for Win8 and newer hosts, since vmscsi_size_delta is set to the initial value of sizeof(vmscsi_win8_extension) rather than zero. This may lead to wrong decisions when using ring_avail_percent_lowater equals to zero. The estimate of max_outstanding_req_per_channel is 'exact' for Win7 and older hosts. A better choice, keeping the algorithm for the estimation simple, is to err the other way around, i.e., to underestimate for Win7 and older but to use the exact value for Win8 and newer.

While testing recent discovery node rework, several items were seen that could be done better with respect to the new trace event logic. 1) in the following msg: kernel: lpfc 0000:44:00.0: start 35 end 35 cnt 0 If cnt is zero in the 1st message, there is no reason to display the 1st message, which is just giving start/end positioning. Fix by not displaying message if cnt is 0. 2) If the driver is loaded with module log verbosity off, and later a single NPIV host instance verbosity is enabled via sysfs, it enables messages on all instances. This is due to the trace log verbosity checks (lpfc_dmp_dbg) looking at the phba only. It should look at the phba and the vport. Fix by enabling a check on both phba and vport. 3) in the following messages: 2904 Firmware Dump Image Present on Adapter 2887 Reset Needed: Attempting Port Recovery... These messages are not necessary for the trace event log, which is primarily for discovery. Fix by changing log level on these 2 messages to LOG_SLI.

Several errors have occurred where the adapter stops or fails but does not raise the register values for the driver to detect failure. Thus driver is unaware of the failure. The failure typically results in I/O timeouts, the I/O timeout handler failing (after several seconds), and the error handler escalating recovery policy and resulting in more errors. Eventually, the driver is in a position where things have spiraled and it can't do recovery because other recovery ops are still outstanding and it becomes unusable. Resolve the situation by having the I/O timeout handler (actually a els, SCSI I/O, NVMe ls, or NVMe I/O timeout), in addition to aborting the I/O, perform a mailbox command and look for a response from the hardware. If the mailbox command fails, it will mark the adapter offline and then invoke the adapter reset handler to clean up. The new I/O timeout test will be limited to a test every 5s. If there are multiple I/O timeouts concurrently, only the 1st I/O timeout will generate the mailbox command. Further testing will only occur once a timeout occurs after a 5s delay from the last mailbox command has expired.

When lpfc is running in NVMET mode and supports the NVME-1 addendum changes, a LIP on a bound NVME Initiator or lipping the lpfc NVMET's link resulted in an Oops in lpfc_nvmet_host_release. The fix requires lpfc NVMET to maintain an additional reference on any node structure that acts as the hosthandle for the NVMET transport. This reference get is a one-time addition, is taken prior to the upcall of an unsolicited LS_REQ, and is released when the NVMET transport releases the hosthandle during the host_release downcall.

If a mailbox command times out, the SLI port is deemed in error and the port is reset. The HBA cleanup is not returning I/Os to the NVMe layer before the port is unregistered. This is due to the HBA being marked offline (!SLI_ACTIVE) and cleanup being done by the mailbox timeout handler rather than an general adapter reset routine. The mailbox timeout handler mailbox handler only cleaned up SCSI I/Os. Fix by reworking the mailbox handler to: - After handling the mailbox error, detect the board is already in failure (may be due to another error), and leave cleanup to the other handler. - If the mailbox command timeout is initial detector of the port error, continue with the board cleanup and marking the adapter offline (!SLI_ACTIVE). Remove the SCSI-only I/O cleanup routine. The generic reset adapter routine that is subsequently invoked, will clean up the I/Os. - Have the reset adapter routine flush all NVMe and SCSI I/Os if the adapter has been marked failed (!SLI_ACTIVE). - Rework the NVMe I/O terminate routine to take a status code to fail the I/O with and update so that cleaned up I/O calls the wqe completion routine. Currently it is bypassing the wqe cleanup and calling the NVMe I/O completion directly. The wqe completion routine will take care of data structure and node cleanup then call the NVMe I/O completion handler.

Target reset is failed by the target as an invalid command. The Target Reset TMF has been obsoleted in T10 for a while, but continues to be used. On (newer) devices, the TMF is rejected causing the reset handler to escalate to adapter resets. Fix by having Target Reset TMF rejections be translated into a LOGO and re-PLOGI with the target device. This provides the same semantic action (although, if the device also supports nvme traffic, it will terminate nvme traffic as well - but it's still recoverable).

A successful task mgmt command is logging errors, making it look like problems were encountered. This is due to log messages for the device/target and bus reset handlers having the LOG_TRACE_EVENT flag set. Fix by adjusting the event flag such that the call to the logging routine only receives a LOG_TRACE_EVENT if a prior call actually failed.
