2021-09-05bnxt_en: fix read of stored FW_PSID version on P5 devicesEdwin Peer2-15/+34
P5 devices store NVM arrays using a different internal representation. This implementation detail permeates into the HWRM API, requiring the caller to explicitly index the array elements in HWRM_NVM_GET_VARIABLE on these devices. Conversely, older devices do not support the indexed mode of operation and require reading the raw NVM content. Fixes: db28b6c77f40 ("bnxt_en: Fix devlink info's stored fw.psid version format.")

2021-09-05net: stmmac: Fix overall budget calculation for rxtx_napiSong Yoong Siang1-4/+6
tx_done is not used for napi_complete_done(). Thus, NAPI busy polling mechanism by gro_flush_timeout and napi_defer_hard_irqs will not able be triggered after a packet is transmitted when there is no receive packet. Fix this by taking the maximum value between tx_done and rx_done as overall budget completed by the rxtx NAPI poll to ensure XDP Tx ZC operation is continuously polling for next Tx frame. This gives benefit of lower packet submission processing latency and jitter under XDP Tx ZC mode. Performance of tx-only using xdp-sock on Intel ADL-S platform is the same with and without this patch. root@intel-corei7-64:~# ./xdpsock -i enp0s30f4 -t -z -q 1 -n 10 sock0@enp0s30f4:1 txonly xdp-drv pps pkts 10.00 rx 0 0 tx 511630 8659520 sock0@enp0s30f4:1 txonly xdp-drv pps pkts 10.00 rx 0 0 tx 511625 13775808 sock0@enp0s30f4:1 txonly xdp-drv pps pkts 10.00 rx 0 0 tx 511619 18892032 Fixes: 132c32ee5bc0 ("net: stmmac: Add TX via XDP zero-copy socket") Cc: <stable@vger.kernel.org> # 5.13.x Co-developed-by: Ong Boon Leong <boon.leong.ong@intel.com> Signed-off-by: Ong Boon Leong <boon.leong.ong@intel.com> Signed-off-by: Song Yoong Siang <yoong.siang.song@intel.com> Signed-off-by: David S.

Check one more time before exiting the API with an error. Fix API to poll at least twice, in case there are other high priority tasks and this API doesn't get CPU cycles for multiple jiffies update. In addition, increase timeout from usecs_to_jiffies(10000) to usecs_to_jiffies(20000), to prevent the case that for CONFIG_100HZ timeout will be a single jiffies. A single jiffies results actual timeout that can be any time between 1usec and 10msec. To solve this, a value of usecs_to_jiffies(20000) ensures that timeout is 2 jiffies.

2021-09-01bnxt_en: Fix 64-bit doorbell operation on 32-bit kernelsMichael Chan2-18/+33
The driver requires 64-bit doorbell writes to be atomic on 32-bit architectures. So we redefined writeq as a new macro with spinlock protection on 32-bit architectures. This created a new warning when we added a new file in a recent patchset. writeq is defined on many 32-bit architectures to do the memory write non-atomically and it generated a new macro redefined warning. This warning was fixed incorrectly in the recent patch. Fix this properly by adding a new bnxt_writeq() function that will do the non-atomic write under spinlock on 32-bit systems. All callers in the driver will now call bnxt_writeq() instead. v2: Need to pass in bp to bnxt_writeq() Use lo_hi_writeq() [suggested by Florian] Reported-by: kernel test robot <lkp@intel.com> Fixes: f9ff578251dc ("bnxt_en: introduce new firmware message API based on DMA pools") Reviewed-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2021-08-31dpaa2-eth: Replace strlcpy with strscpyJason Wang1-4/+4
The strlcpy should not be used because it doesn't limit the source length. As linus says, it's a completely useless function if you can't implicitly trust the source string - but that is almost always why people think they should use it! All in all the BSD function will lead some potential bugs. But the strscpy doesn't require reading memory from the src string beyond the specified "count" bytes, and since the return value is easier to error-check than strlcpy()'s. In addition, the implementation is robust to the string changing out from underneath it, unlike the current strlcpy() implementation. Thus, We prefer using strscpy instead of strlcpy.

2021-08-31sch_htb: Fix inconsistency when leaf qdisc creation failsMaxim Mikityanskiy3-13/+9
In HTB offload mode, qdiscs of leaf classes are grafted to netdev queues. sch_htb expects the dev_queue field of these qdiscs to point to the corresponding queues. However, qdisc creation may fail, and in that case noop_qdisc is used instead. Its dev_queue doesn't point to the right queue, so sch_htb can lose track of used netdev queues, which will cause internal inconsistencies. This commit fixes this bug by keeping track of the netdev queue inside struct htb_class. All reads of cl->leaf.q->dev_queue are replaced by the new field, the two values are synced on writes, and WARNs are added to assert equality of the two values. The driver API has changed: when TC_HTB_LEAF_DEL needs to move a queue, the driver used to pass the old and new queue IDs to sch_htb. Now that there is a new field (offload_queue) in struct htb_class that needs to be updated on this operation, the driver will pass the old class ID to sch_htb instead (it already knows the new class ID).

2021-08-30ixp4xx_eth: Stop referring to GPIOsLinus Walleij1-56/+28
The driver is being passed interrupts, then looking up the same interrupts as GPIOs a second time to convert them into interrupts and set properties on them. This is pointless: the GPIO and irqchip APIs of a GPIO chip are orthogonal. Just request the interrupts and be done with it, drop reliance on any GPIO functions or definitions. Use devres-managed functions and add a small devress quirk to unregister the clock as well and we can rely on devres to handle all the resources and cut down a bunch of boilerplate in the process.

2021-08-30ixp4xx_eth: make ptp support a platform driverArnd Bergmann5-34/+78
After the recent ixp4xx cleanups, the ptp driver has gained a build failure in some configurations: drivers/net/ethernet/xscale/ptp_ixp46x.c: In function 'ptp_ixp_init': drivers/net/ethernet/xscale/ptp_ixp46x.c:290:51: error: 'IXP4XX_TIMESYNC_BASE_VIRT' undeclared (first use in this function) Avoid the last bit of hardcoded constants from platform headers by turning the ptp driver bit into a platform driver and passing the IRQ and MMIO address as resources. This is a bit tricky: - The interface between the two drivers is now the new ixp46x_ptp_find() function, replacing the global ixp46x_phc_index variable. The call is done as late as possible, in hwtstamp_set(), to ensure that the ptp device is fully probed. - As the ptp driver is now called by the network driver, the link dependency is reversed, which in turn requires a small Makefile hack - The GPIO number is still left hardcoded. This is clearly not great, but it can be addressed later. Note that commit 98ac0cc270b7 ("ARM: ixp4xx: Convert to MULTI_IRQ_HANDLER") changed the IRQ number to something meaningless. Passing the correct IRQ in a resource fixes this. - When the PTP driver is disabled, ethtool .get_ts_info() now correctly lists only software timestamping regardless of the hardware.
