2022-10-01net/mlx5e: xsk: Use queue indices starting from 0 for XSK queuesMaxim Mikityanskiy
In the initial implementation of XSK in mlx5e, XSK RQs coexisted with regular RQs in the same channel. The main idea was to allow RSS work the same for regular traffic, without need to reconfigure RSS to exclude XSK queues. However, this scheme didn't prove to be beneficial, mainly because of incompatibility with other vendors. Some tools don't properly support using higher indices for XSK queues, some tools get confused with the double amount of RQs exposed in sysfs. Some use cases are purely XSK, and allocating the same amount of unused regular RQs is a waste of resources. This commit changes the queuing scheme to the standard one, where XSK RQs replace regular RQs on the channels where XSK sockets are open. Two RQs still exist in the channel to allow failsafe disable of XSK, but only one is exposed at a time. The next commit will achieve the desired memory save by flushing the buffers when the regular RQ is unused. As the result of this transition: 1. It's possible to use RSS contexts over XSK RQs. 2. It's possible to dedicate all queues to XSK. 3. When XSK RQs coexist with regular RQs, the admin should make sure no unwanted traffic goes into XSK RQs by either excluding them from RSS or settings up the XDP program to return XDP_PASS for non-XSK traffic. 4. When using a mixed fleet of mlx5e devices and other netdevs, the same configuration can be applied. If the application supports the fallback to copy mode on unsupported drivers, it will work too.

2022-10-01net/mlx5e: Optimize RQ page deallocationMaxim Mikityanskiy
mlx5e_free_rx_mpwqe loops over all pages of a MPWQE, calling mlx5e_page_release for ones that are not scheduled for XDP_TX or XDP_REDIRECT; and mlx5e_page_release checks whether it's an XSK RQ or a regular one for each page/XSK frame. This check can be moved outside the loop to reduce the number of branches. mlx5e_free_rx_wqe loops over all fragments, calling mlx5e_page_release for the ones that are last in a page; and mlx5e_page_release checks whether it's an XSK RQ or a regular one for each fragment. Using the fact that XSK doesn't support multiple fragments, it can be optimized for both XSK and regular usages: 1. Make an early check for XSK and call its deallocator directly, saving 3 branches (loop condition, frag->last_in_page and selection of deallocator). 2. Call the regular deallocator directly in the non-XSK case, saving a branch per fragment, except the first one. After the changes, mlx5e_page_release is removed, as there are no callers left.

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.

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: 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: 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.

2022-09-30nfp: refine the ABI of getting `sp_indiff` infoYinjun Zhang
Considering that whether application firmware is indifferent to port speed is a firmware property instead of port property, now use a new rtsym to get the property instead of parsing per-port tlv caps. With this change, relevant code is moved to `nfp_main` layer.

rtl_disable_rxdvgate() is used for disable RXDV_GATE. It is opposite function of rtl_enable_rxdvgate(). Disable RXDV_GATE does not have to delay. So in this patch, also remove the delay after disale RXDV_GATE.

In ti_find_clock_provider(), of_find_node_by_name() will call of_node_put() for the 'from' argument, possibly putting the node one too many times. Let's maintain the of_node_get() from the previous search and only put when we're exiting the function early. This should avoid a misbalanced reference count on the node.

2022-09-30clk: vc5: Use regmap_{set,clear}_bits() where appropriateLars-Peter Clausen
regmap_set_bits() and regmap_clear_bits() are variations of regmap_update_bits() that can be used if all bits of the mask have to be set to either 1 or 0 respectively. Update the versaclk driver to use regmap_set_bits() and regmap_clear_bits() where appropriate. This results in slightly more compact code and also makes the intention of the code clearer which can help with review.

2022-09-30clk: vc5: Check IO access resultsLars-Peter Clausen
The devices of the versaclk clock generator family use an I2C control bus. IO access on an I2C bus can fail for various reasons. The driver currently ignores the return value of most IO operations. This results in silent failure. To avoid this check the return value and in case of an error abort the operation and propagate the error code to the caller.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk driver fixes from Stephen Boyd: "Here's the last batch of clk driver fixes for this release. These patches fix serious problems, for example, i.MX has an issue where changing the NAND clk frequency hangs the system. On Allwinner H6 the GPU is being overclocked which could lead to long term hardware damage. And finally on some Broadcom SoCs the serial console stopped working because the clk tree hierarchy description got broken by an inadvertant DT node name change. That's fixed by using 'clock-output-names' to generate a stable and unique name for clks so the framework can properly link things up. There's also a couple build fixes in here. One to fix CONFIG_OF=n builds and one to avoid an array out of bounds bug that happens during clk registration on microchip. I hope that KASAN would have found that OOB problem, but probably KASAN wasn't attempted.
