2022-10-01net/mlx5e: xsk: Use xsk_buff_alloc_batch on legacy RQMaxim Mikityanskiy
XSK provides a function to allocate frames in batches for more efficient processing. This commit starts using this function on legacy RQ, adding a special case for XSK. The new branch introduced basically replaces the branch that was removed from the same place a few commits before. A check is made that DMA sync is not needed, because the batching allocator falls back to returning one frame when DMA sync is needed, and this is best handled by the loop in the standard case. Performance improvement is up to 8% in the aligned mode and up to 9% in the unaligned mode. Aligned mode, 2048-byte frames: 12.8 Mpps -> 13.5 Mpps Aligned mode, 4096-byte frames: 11.5 Mpps -> 12.4 Mpps Unaligned mode, 2048-byte frames: 12.2 Mpps -> 13.4 Mpps Unaligned mode, 3072-byte frames: 11.6 Mpps -> 12.5 Mpps Unaligned mode, 4096-byte frames: 11.2 Mpps -> 12.2 Mpps CPU: Intel(R) Xeon(R) Gold 6240 CPU @ 2.60GHz Signed-off-by: Maxim Mikityanskiy <maximmi@nvidia.com> Reviewed-by: Tariq Toukan <tariqt@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-10-01net/mlx5e: xsk: Split out WQE allocation for legacy XSK RQMaxim Mikityanskiy
Allocation of XSK frames on legacy RQ may be made more efficient with a specialized routine that relies on certain assumptions, such as there is only one fragment, allocation units (XSK frames) are not shared among multiple packets. It reduces the number of branches both in the XSK code and in the regular RQ, because with this approach there is only a single check whether it's an XSK or regular RQ.

2022-10-01net/mlx5e: Remove the outer loop when allocating legacy RQ WQEsMaxim Mikityanskiy
Legacy RQ WQEs are allocated in a loop in small batches (8 WQEs). As partial batches are allowed, there is no point to have a loop in a loop, so the outer loop is removed, and the batch size is increased up to the total number of WQEs to allocate, still not smaller than 8.

2022-10-01net/mlx5e: Use partial batches in legacy RQMaxim Mikityanskiy
Legacy RQ allocates WQEs in batches. If the batch allocation fails, the pages of the allocated part are released. This commit changes this behavior to allow to use the pages that have been already allocated. After this change, we need to be careful about indexing rq->wqe.frags[]. The WQ size is a power of two that divides by wqe_bulk (8), and the old code used whole bulks, which allowed to use indices [8*K; 8*K+7] without overflowing. Now that the bulks may be partial, the range can start at any location (not only at 8*K), so we need to wrap them around to avoid out-of-bounds array access.

2022-10-01net/mlx5e: Make the wqe_index_mask calculation more exactMaxim Mikityanskiy
The old calculation of wqe_index_mask may give false positives, i.e. request bulking of pairs of WQEs when not strictly needed, for example, when the first fragment size is equal to the PAGE_SIZE, bulking is not needed, even if the number of fragments is odd. Make the calculation more exact to cut false positives.

2022-10-01net/mlx5e: Introduce wqe_index_mask for legacy RQMaxim Mikityanskiy
When fragments of different WQEs share the same page, mlx5e_post_rx_wqes must wait until the old WQE stops using the page, only then the new WQE can allocate the new page. Essentially, it means that if WQE index i is still in use, the allocation must stop before `i % bulk`, where bulk is the number of WQEs that may share the same page. As bulk is always a power of two, `i % bulk = i & (bulk - 1)`, and the new wqe_index_mask field will be equal to `bulk - 1`. At the same time, wqe_bulk remains for optimization purposes and stores `max(bulk, 8)`, which allows to skip the allocation until we have at least 8 WQEs free.

2022-10-01net/mlx5e: xsk: Drop the check for XSK state in mlx5e_xsk_wakeupMaxim Mikityanskiy
The MLX5E_CHANNEL_STATE_XSK flag checked in mlx5e_xsk_wakeup indicates that XSK queues are open, but not necessarily activated. This check is not very useful, because: 0. Both XSK setup and netdev state transitions take the same state_lock mutex, so they can't happen at the same time. 1. If the netdev is up, xsk_is_bound can return true only when MLX5E_CHANNEL_STATE_XSK is set on the corresponding channel. mlx5e_xsk_wakeup is only called when xsk_is_bound is true. 2. If the XSK socket is bound, and the netdev is going up or down, mlx5e_xsk_wakeup can take one of two branches, depending on the return value of napi_if_scheduled_mark_missed: 2.1. True means one of two things: either NAPI was enabled at this point, which means MLX5E_CHANNEL_STATE_XSK was also set; or NAPI was disabled, and nothing really happened. 2.2. False means that NAPI was enabled by this point, which also implies MLX5E_CHANNEL_STATE_XSK was set. Additionally, mlx5e_xsk_wakeup contains a following check for MLX5E_SQ_STATE_ENABLED on async_icosq, and this flag implies MLX5E_CHANNEL_STATE_XSK too on XSK channels. As checking this flag doesn't cut any flows, remove the check.

2022-10-01ALSA: hda/hdmi: Don't skip notification handling during PM operationTakashi Iwai
The HDMI driver skips the notification handling from the graphics driver when the codec driver is being in the PM operation. This behavior was introduced by the commit eb399d3c99d8 ("ALSA: hda - Skip ELD notification during PM process"). This skip may cause a problem, as we may miss the ELD update when the connection/disconnection happens right at the runtime-PM operation of the audio codec. Although this workaround was valid at that time, it's no longer true; the fix was required just because the ELD update procedure needed to wake up the audio codec, which had lead to a runtime-resume during a runtime-suspend. Meanwhile, the ELD update procedure doesn't need a codec wake up any longer since the commit 788d441a164c ("ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling"); i.e. there is no much reason for skipping the notification. Let's drop those checks for addressing the missing notification.

2022-09-30ext4: remove cantfind_ext4 error handlerJason Yan
The 'cantfind_ext4' error handler is just a error msg print and then goto failed_mount. This two level goto makes the code complex and not easy to read. The only benefit is that is saves a little bit code. However some branches can merge and some branches dot not even need it. So do some refactor and remove it.

2022-09-30ext4: goto right label 'failed_mount3a'Jason Yan
Before these two branches neither loaded the journal nor created the xattr cache. So the right label to goto is 'failed_mount3a'. Although this did not cause any issues because the error handler validated if the pointer is null. However this still made me confused when reading the code. So it's still worth to modify to goto the right label.

2022-09-30ext4: adjust fast commit disable judgement order in ext4_fc_track_inodeYe Bin
If fastcommit is already disabled, there isn't need to mark inode ineligible. So move 'ext4_fc_disabled()' judgement bofore 'ext4_should_journal_data(inode)' judgement which can avoid to do meaningless judgement.
