2024-07-01Merge branch 'bnxt_en-ptp' into mainDavid S. Miller4-83/+252
Michael Chan says: ==================== bnxt_en: PTP updates for net-next The first 5 patches implement the PTP feature on the new BCM5760X chips. The main new hardware feature is the new TX timestamp completion which enables the driver to retrieve the TX timestamp in NAPI without deferring to the PTP worker. The last 5 patches increase the number of TX PTP packets in-flight from 1 to 4 on the older BCM5750X chips. On these older chips, we need to call firmware in the PTP worker to retrieve the timestamp. We use an arry to keep track of the in-flight TX PTP packets. v2: Patch #2: Fix the unwind of txr->is_ts_pkt when bnxt_start_xmit() aborts. Patch #4: Set the SKBTX_IN_PROGRESS flag for timestamp packets. ==================== Signed-off-by: David S. Miller <[email protected]>
2024-07-01bnxt_en: Remove atomic operations on ptp->tx_availPavan Chebbi3-22/+31
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.

2024-07-01bnxt_en: Increase the max total outstanding PTP TX packets to 4Pavan Chebbi4-30/+68
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.

2024-07-01bnxt_en: Remove an impossible condition check for PTP TX pending SKBPavan Chebbi3-13/+4
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 Chebbi3-28/+40
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.

The new BCM5760X chips will return the timestamp of TX packets in a new completion. Add logic in __bnxt_poll_work() to handle this completion type to retrieve the timestamp.

2024-07-01bnxt_en: Allow some TX packets to be unprocessed in NAPIMichael Chan1-6/+15
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.

The kernel test robot reported that clang no longer compiles the 32-bit x86 kernel in some configurations due to commit 95ece48165c1 ("locking/atomic/x86: Rewrite x86_32 arch_atomic64_{,fetch}_{and,or,xor}() functions"). The build fails with arch/x86/include/asm/cmpxchg_32.h:149:9: error: inline assembly requires more registers than available and the reason seems to be that not only does the cmpxchg8b instruction need four fixed registers (EDX:EAX and ECX:EBX), with the emulation fallback the inline asm also wants a fifth fixed register for the address (it uses %esi for that, but that's just a software convention with cmpxchg8b_emu). Avoiding using another pointer input to the asm (and just forcing it to use the "0(%esi)" addressing that we end up requiring for the sw fallback) seems to fix the issue.

2024-06-30erofs: ensure m_llen is reset to 0 if metadata is invalidGao Xiang1-0/+2
Sometimes, the on-disk metadata might be invalid due to user interrupts, storage failures, or other unknown causes. In that case, z_erofs_map_blocks_iter() may still return a valid m_llen while other fields remain invalid (e.g., m_plen can be 0). Due to the return value of z_erofs_scan_folio() in some path will be ignored on purpose, the following z_erofs_scan_folio() could then use the invalid value by accident. Let's reset m_llen to 0 to prevent this. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Gao Xiang <[email protected]>

Edward Cree says: ==================== ethtool: track custom RSS contexts in the core Make the core responsible for tracking the set of custom RSS contexts, their IDs, indirection tables, hash keys, and hash functions; this lets us get rid of duplicative code in drivers, and will allow us to support netlink dumps later. This series only moves the sfc EF10 & EF100 driver over to the new API; other drivers (mvpp2, octeontx2, mlx5, sfc/siena, bnxt_en) can be converted afterwards and the legacy API removed. ==================== Link: https://patch.msgid.link/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

The core is now responsible for allocating IDs and a memory region for us to store our state (struct efx_rss_context_priv), so we no longer need efx_alloc_rss_context_entry() and friends. Since the contexts are now maintained by the core, use the core's lock (net_dev->ethtool->rss_lock), rather than our own mutex (efx->rss_lock), to serialise access against changes; and remove the now-unused efx->rss_lock from struct efx_nic.

Add a new API to create/modify/remove RSS contexts, that passes in the newly-chosen context ID (not as a pointer) rather than leaving the driver to choose it on create. Also pass in the ctx, allowing drivers to easily use its private data area to store their hardware-specific state. Keep the existing .set_rxfh API for now as a fallback, but deprecate it for custom contexts (rss_context != 0).
