2024-07-01RDMA/bnxt_re: Update the correct DB FIFO depth and mask for GenP7Selvin Xavier
GenP5 and P7 devices have different DB FIFO depth. Use different values based on the chip context. Instead of hardcoding doorbell FIFO related values, get it from the HWRM interface. Maintain backward compatibility by having default values when FW is not providing the doorbell FIFO related values.

2024-07-01bnxt_en: Remove atomic operations on ptp->tx_availPavan Chebbi
Now that we require the spinlock to protect ptp->txts_prod, change ptp->tx_avail to non-atomic and protect it under the same spinlock. Add a new helper function bnxt_ptp_get_txts_prod() to decrement ptp->tx_avail under spinlock and return the producer.

Start accepting up to 4 TX TS requests on BCM5750X (P5) chips. These PTP TX packets will be queued in the ptp->txts_req[] array waiting for the TX timestamp to complete. The entries in the array will be managed by a producer and consumer index. The producer index is updated under spinlock since multiple TX rings can try to send PTP packets at the same time.

In the current 5750X PTP code paths, there is always at most one TX SKB requested for timestamp and we won't accept another one until we have retrieved the timestamp or it has timed out. Remove the unnecessary check in bnxt_get_tx_ts_p5() for a pending SKB and change the function to void.

2024-07-01bnxt_en: Refactor all PTP TX timestamp fields into a structPavan Chebbi
On the older 5750X (P5) chips, we currently support only 1 TX PTP packet in-flight waiting for the timestamp. Refactor the datastructures to prepare to support up to 4 TX PTP packets. Combine all fields required for PTP TX timestamp query into one structure. An array of this structure will be added in follow-on patches to support multiple outstanding TX timestamps.

2024-07-01bnxt_en: Allow some TX packets to be unprocessed in NAPIMichael Chan
The driver's current logic will always free all the TX SKBs up to txr->tx_hw_cons within NAPI. In the next patches, we'll be adding logic to handle TX timestamp completion and we may need to hold some remaining TX SKBs if we don't have the timestamp completions yet. Modify __bnxt_poll_work_done() to clear each event bit separately to allow bnapi->tx_int() to decide whether to clear BNXT_TX_CMP_EVENT or not. bnapi->tx_int() will not clear BNXT_TX_CMP_EVENT if some TX SKBs are held waiting for TX timestamps. Note that legacy chips will never hold any SKBs this way. The SKB is always deferred to the PTP worker slow path to retrieve the timestamp from firmware. On the new P7 chips, the timestamp is returned by the hardware directly and we can retrieve it directly from NAPI.

2024-07-01mtd: rawnand: mxc: support software ECCSascha Hauer
With these changes the driver can be used with software BCH ECC which is useful for NAND chips that require a stronger ECC than the i.MX hardware supports. The controller normally interleaves user data with OOB data when accessing the NAND chip. With Software BCH ECC we write the data to the NAND in a way that the raw data on the NAND chip matches the way the NAND layer sees it. This way commands like NAND_CMD_RNDOUT work as expected. This was tested on i.MX27 but should work on the other SoCs supported by this driver as well.

2024-07-01mtd: rawnand: mxc: separate page read from ecc calcSascha Hauer
Our read_page hook currently reads out a page and also counts and returns the number of bitflips. In upcoming exec_op conversion we'll need to read the page data in exec_op, but the bitflip information will be needed in mxc_nand_read_page(). To ease exec_op conversion separate the page read out from the bitflip evaluation. For the v2/v3 controllers we can leave the bitflip information in the status register for later evaluation. For the v1 controller this is not possible, because the status register is overwritten with each subpage read. We therefore store the bitflip information in the private data.

The Pin Multiplex attachment in Rev.1.10 of the R-Car V4H Series Hardware User's Manual still has two alternate pins named both "FXR_TXEN[AB]". To differentiate, the pin control driver uses "FXR_TXEN[AB]" and "FXR_TXEN[AB]_X", which were considered temporary names until the conflict was sorted out. Fix this by adopting R-Car V4M naming: - Rename "FXR_TXEN[AB]" to "FXR_TXEN[AB]_A", - Rename "FXR_TXEN[AB]_X" to "FXR_TXEN[AB]_B".

2024-07-01PCI/DPC: Fix use-after-free on concurrent DPC and hot-removalLukas Wunner
Keith reports a use-after-free when a DPC event occurs concurrently to hot-removal of the same portion of the hierarchy: The dpc_handler() awaits readiness of the secondary bus below the Downstream Port where the DPC event occurred. To do so, it polls the config space of the first child device on the secondary bus. If that child device is concurrently removed, accesses to its struct pci_dev cause the kernel to oops. That's because pci_bridge_wait_for_secondary_bus() neglects to hold a reference on the child device. Before v6.3, the function was only called on resume from system sleep or on runtime resume. Holding a reference wasn't necessary back then because the pciehp IRQ thread could never run concurrently. (On resume from system sleep, IRQs are not enabled until after the resume_noirq phase. And runtime resume is always awaited before a PCI device is removed.) However starting with v6.3, pci_bridge_wait_for_secondary_bus() is also called on a DPC event. Commit 53b54ad074de ("PCI/DPC: Await readiness of secondary bus after reset"), which introduced that, failed to appreciate that pci_bridge_wait_for_secondary_bus() now needs to hold a reference on the child device because dpc_handler() and pciehp may indeed run concurrently. The commit was backported to v5.10+ stable kernels, so that's the oldest one affected. Add the missing reference acquisition.
