2022-10-03net/mlx5e: xsk: Optimize for unaligned mode with 3072-byte framesMaxim Mikityanskiy4-3/+61
When XSK frame size is 3072 (or another power of two multiplied by 3), KLM mechanism for NIC virtual memory page mapping can be optimized by replacing it with KSM. Before this change, two KLM entries were needed to map an XSK frame that is not a power of two: one entry maps the UMEM memory up to the frame length, the other maps the rest of the stride to the garbage page. When the frame length divided by 3 is a power of two, it can be mapped using 3 KSM entries, and the fourth will map the rest of the stride to the garbage page. All 4 KSM entries are of the same size, which allows for a much faster lookup. Frame size 3072 is useful in certain use cases, because it allows packing 4 frames into 3 pages. Generally speaking, other frame sizes equal to PAGE_SIZE minus a power of two can be optimized in a similar way, but it will require many more KSMs per frame, which slows down UMRs a little bit, but more importantly may hit the limit for the maximum number of KSM entries.

2022-10-03net/mlx5e: xsk: Print a warning in slow configurationsMaxim Mikityanskiy1-0/+9
On striding RQ, when the XSK frame size doesn't match the MKey page size, KLM is used for memory mappings, which is a slower mechanism than MTT or KSM. It may happen in two cases: 1. Frame size is not a power of two (only possible in the unaligned mode of XSK). 2. Frame size is 2048 bytes, and the firmware doesn't support MKey pages smaller than 4096 bytes. Depending on the case, print a warning and recommend to disable striding RQ or upgrade the firmware.

2022-10-03net/mlx5e: xsk: Use KLM to protect frame overrun in unaligned modeMaxim Mikityanskiy4-10/+90
XSK RQs support striding RQ linear mode, but the stride size may be bigger than the XSK frame size, because: 1. The stride size must be a power of two. 2. The stride size must be equal to the UMR page size. Each XSK frame is treated as a separate page, because they aren't necessarily adjacent in physical memory, so the driver can't put more than one stride per page. 3. The minimal MTT page size is 4096 on older firmware. That means that if XSK frame size is 2048 or not a power of two, the strides may be bigger than XSK frames. Normally, it's not a problem if the hardware enforces the MTU. However, traffic between vports skips the hardware MTU check, and oversized packets may be received. If an oversized packet is bigger than the XSK frame but not bigger than the stride, it will cause overwriting of the adjacent UMEM region. If the packet takes more than one stride, they can be recycled for reuse, so it's not a problem when the XSK frame size matches the stride size. Work around the above issue by leveraging KLM to make a more fine-grained mapping. The beginning of each stride is mapped to the frame memory, and the padding up to the closest power of two is mapped to the overflow page that doesn't belong to UMEM. This way, application data corruption won't happen upon receiving packets bigger than MTU.

Ensure that there is always an even amount of MTTs in a UMR WQE, so that complete octwords are formed, and no garbage is mapped. Drop extra alignment in MLX5_MTT_OCTW that may cause setting too big ucseg->xlt_octowords, also leading to mapping garbage. Generalize some calculations by introducing the MLX5_OCTWORD constant.

2022-10-03net/mlx5e: xsk: Improve need_wakeup logicMaxim Mikityanskiy4-37/+23
XSK need_wakeup mechanism allows the driver to stop busy waiting for buffers when the fill ring is empty, yield to the application and signal it that the driver needs to be waken up after the application refills the fill ring. Add protection against the race condition on the RX (refill) side: if the application refills buffers after xskrq->post_wqes is called, but before mlx5e_xsk_update_rx_wakeup, NAPI will exit, skipping taking these buffers to the hardware WQ, and the application won't wake it up again. Optimize the whole need_wakeup logic, removing unneeded flows, to compensate for this new check.

2022-10-03net: mvpp2: fix mvpp2 debugfs leakRussell King (Oracle)3-3/+21
When mvpp2 is unloaded, the driver specific debugfs directory is not removed, which technically leads to a memory leak. However, this directory is only created when the first device is probed, so the hardware is present. Removing the module is only something a developer would to when e.g. testing out changes, so the module would be reloaded. So this memory leak is minor. The original attempt in commit fe2c9c61f668 ("net: mvpp2: debugfs: fix memory leak when using debugfs_lookup()") that was labelled as a memory leak fix was not, it fixed a refcount leak, but in doing so created a problem when the module is reloaded - the directory already exists, but mvpp2_root is NULL, so we lose all debugfs entries. This fix has been reverted. This is the alternative fix, where we remove the offending directory whenever the driver is unloaded.

This patch just updates comments throughout the IPA code. Transaction state is now tracked using indexes into an array rather than linked lists, and a few comments refer to the "old way" of doing things. The description of how transactions are used was changed to refer to "operations" rather than "commands", to (hopefully) remove a possible ambiguity. IPA register offsets and fields are now handled differently as well, and the register documentation is updated to better describe the code. A few minor updates to comments were made (e.g., adding a missing word, fixing a typo or punctuation, etc.). Finally, the local macro atomic_dec_not_zero() is no longer used, so it is deleted.

2022-10-03mm: hugetlb: eliminate memory-less nodes handlingMuchun Song1-2/+6
The memory-notify-based approach aims to handle meory-less nodes, however, it just adds the complexity of code as pointed by David in thread [1]. The handling of memory-less nodes is introduced by commit 4faf8d950ec4 ("hugetlb: handle memory hot-plug events"). >From its commit message, we cannot find any necessity of handling this case. So, we can simply register/unregister sysfs entries in register_node/unregister_node to simlify the code. BTW, hotplug callback added because in hugetlb_register_all_nodes() we register sysfs nodes only for N_MEMORY nodes, seeing commit 9b5e5d0fdc91, which said it was a preparation for handling memory-less nodes via memory hotplug. Since we want to remove memory hotplug, so make sure we only register per-node sysfs for online (N_ONLINE) nodes in hugetlb_register_all_nodes(). https://lore.kernel.org/linux-mm/[email protected]/ [1] Link: https://lkml.kernel.org/r/[email protected] Suggested-by: David Hildenbrand <[email protected]> Signed-off-by: Muchun Song <[email protected]> Acked-by: David Hildenbrand <[email protected]> Cc: Andi Kleen <[email protected]> Cc: Greg Kroah-Hartman <[email protected]> Cc: Mike Kravetz <[email protected]> Cc: Oscar Salvador <[email protected]> Cc: Rafael J.

2022-10-03mm: hugetlb: simplify per-node sysfs creation and removalMuchun Song1-136/+3
Patch series "simplify handling of per-node sysfs creation and removal", v4. This patch (of 2): The following commit offload per-node sysfs creation and removal to a kworker and did not say why it is needed. And it also said "I don't know that this is absolutely required". It seems like the author was not sure as well. Since it only complicates the code, this patch will revert the changes to simplify the code. 39da08cb074c ("hugetlb: offload per node attribute registrations") We could use memory hotplug notifier to do per-node sysfs creation and removal instead of inserting those operations to node registration and unregistration. Then, it can reduce the code coupling between node.c and hugetlb.c. Also, it can simplify the code.

zram_table_entry::flags stores object size in the lower bits and zram pageflags in the upper bits. However, for some reason, we use 24 lower bits, while maximum zram object size is PAGE_SIZE, which requires PAGE_SHIFT bits (up to 16 on arm64). This wastes 24 - PAGE_SHIFT bits that we can use for additional zram pageflags instead. Also add a BUILD_BUG_ON() to alert us should we run out of bits in zram_table_entry::flags.
