2024-05-13KEYS: asymmetric: Add missing dependencies of FIPS_SIGNATURE_SELFTESTEric Biggers

2024-05-13Merge tag 'for-6.10/io_uring-20240511' of git://git.kernel.dk/linuxLinus Torvalds
Pull io_uring updates from Jens Axboe: - Greatly improve send zerocopy performance, by enabling coalescing of sent buffers. MSG_ZEROCOPY already does this with send(2) and sendmsg(2), but the io_uring side did not. In local testing, the crossover point for send zerocopy being faster is now around 3000 byte packets, and it performs better than the sync syscall variants as well. This feature relies on a shared branch with net-next, which was pulled into both branches. - Unification of how async preparation is done across opcodes. Previously, opcodes that required extra memory for async retry would allocate that as needed, using on-stack state until that was the case. If async retry was needed, the on-stack state was adjusted appropriately for a retry and then copied to the allocated memory. This led to some fragile and ugly code, particularly for read/write handling, and made storage retries more difficult than they needed to be. Allocate the memory upfront, as it's cheap from our pools, and use that state consistently both initially and also from the retry side. - Move away from using remap_pfn_range() for mapping the rings. This is really not the right interface to use and can cause lifetime issues or leaks. Additionally, it means the ring sq/cq arrays need to be physically contigious, which can cause problems in production with larger rings when services are restarted, as memory can be very fragmented at that point. Move to using vm_insert_page(s) for the ring sq/cq arrays, and apply the same treatment to mapped ring provided buffers. This also helps unify the code we have dealing with allocating and mapping memory. Hard to see in the diffstat as we're adding a few features as well, but this kills about ~400 lines of code from the codebase as well. - Add support for bundles for send/recv. When used with provided buffers, bundles support sending or receiving more than one buffer at the time, improving the efficiency by only needing to call into the networking stack once for multiple sends or receives. - Tweaks for our accept operations, supporting both a DONTWAIT flag for skipping poll arm and retry if we can, and a POLLFIRST flag that the application can use to skip the initial accept attempt and rely purely on poll for triggering the operation. Both of these have identical flags on the receive side already. - Make the task_work ctx locking unconditional. We had various code paths here that would do a mix of lock/trylock and set the task_work state to whether or not it was locked. All of that goes away, we lock it unconditionally and get rid of the state flag indicating whether it's locked or not. The state struct still exists as an empty type, can go away in the future. - Add support for specifying NOP completion values, allowing it to be used for error handling testing. - Use set/test bit for io-wq worker flags. Not strictly needed, but also doesn't hurt and helps silence a KCSAN warning. - Cleanups for io-wq locking and work assignments, closing a tiny race where cancelations would not be able to find the work item reliably. - Misc fixes, cleanups, and improvements * tag 'for-6.10/io_uring-20240511' of git://git.kernel.dk/linux: (97 commits) io_uring: support to inject result for NOP io_uring: fail NOP if non-zero op flags is passed in io_uring/net: add IORING_ACCEPT_POLL_FIRST flag io_uring/net: add IORING_ACCEPT_DONTWAIT flag io_uring/filetable: don't unnecessarily clear/reset bitmap io_uring/io-wq: Use set_bit() and test_bit() at worker->flags io_uring/msg_ring: cleanup posting to IOPOLL vs !IOPOLL ring io_uring: Require zeroed sqe->len on provided-buffers send io_uring/notif: disable LAZY_WAKE for linked notifs io_uring/net: fix sendzc lazy wake polling io_uring/msg_ring: reuse ctx->submitter_task read using READ_ONCE instead of re-reading it io_uring/rw: reinstate thread check for retries io_uring/notif: implement notification stacking io_uring/notif: simplify io_notif_flush() net: add callback for setting a ubuf_info to skb net: extend ubuf_info callback to ops structure io_uring/net: support bundles for recv io_uring/net: support bundles for send io_uring/kbuf: add helpers for getting/peeking multiple buffers io_uring/net: add provided buffer support for IORING_OP_SEND ...

[WHY] HW for DCN401 is presented with a small I2C speed fluctuation that exceeds the hard cap limitation of 100kHz occasionally. This violates compliance requirement and will result in failure in compliance. [HOW] After various measurements and traceback to previous generation HW, DCN IP, SI and SW driver agrees that we can reduce I2C speed to 95kHz to address the I2C spped fluctuation in DCN401.

2024-05-13drm/amd/display: Allow higher DSC slice support for small timings on dcn401Wenjing Liu
[WHY] DML2.1 has added the support to determine ODM combine based on DSC slice count limitation. This support would allow us to support DSC slice higher than 4 on small timings. The change will allow higher DSC slice support independent from pixel clock in use. [HOW] Add a DCN401 get_enc_caps function to allow the support for DSC slice count higher than 4.

2024-05-13drm/amd/display: Don't offload flip if not only address updateAlvin Lee
[WHAT & HOW] Fast updates can consist of some stream updates as well (i.e., out_csc). In these cases we should not offload the flip to FW as we can only offload address only updates to FW.

2024-05-13drm/amd/display: Check UHBR13.5 cap when determining max link capGeorge Shen
[WHY] UHBR13.5 support is optional, even if UHBR20 is supported by the device. If source supports max UHBR13.5 while sink, cable and LTTPR support UHBR20 but not UHBR13.5, UHBR10 should be used as the max link cap.

2024-05-13drm/amd/display: Add left edge pixel for YCbCr422/420 + ODM pipe splitWenjing Liu
[WHY] Currently 3-tap chroma subsampling is used for YCbCr422/420. When ODM pipesplit is used, pixels on the left edge of ODM slices need one extra pixel from the right edge of the previous slice to calculate the correct chroma value. Without this change, the chroma value is slightly different than expected. This is usually imperceptible visually, but it impacts test pattern CRCs for compliance test automation. [HOW] Update logic to use the register for adding extra left edge pixel for YCbCr422/420 ODM cases.
