The Arm 'Realview' reference platform still supports ARM11MPCore in principle, but this was never a product, and the CPU support will get cleaned up later on. Another series updates the mv78xx0 platform, which has been similarly neglected for a while, but should work properly again now.

2023-04-24lan966x: Don't use xdp_frame when action is XDP_TXHoratiu Vultur
When the action of an xdp program was XDP_TX, lan966x was creating a xdp_frame and use this one to send the frame back. But it is also possible to send back the frame without needing a xdp_frame, because it is possible to send it back using the page. And then once the frame is transmitted is possible to use directly page_pool_recycle_direct as lan966x is using page pools. This would save some CPU usage on this path, which results in higher number of transmitted frames.

2023-04-24tsnep: Add XDP socket zero-copy RX supportGerhard Engleder
Add support for XSK zero-copy to RX path. The setup of the XSK pool can be done at runtime. If the netdev is running, then the queue must be disabled and enabled during reconfiguration. This can be done easily with functions introduced in previous commits. A more important property is that, if the netdev is running, then the setup of the XSK pool shall not stop the netdev in case of errors. A broken netdev after a failed XSK pool setup is bad behavior. Therefore, the allocation and setup of resources during XSK pool setup is done only before any queue is disabled. Additionally, freeing and later allocation of resources is eliminated in some cases. Page pool entries are kept for later use. Two memory models are registered in parallel. As a result, the XSK pool setup cannot fail during queue reconfiguration. In contrast to other drivers, XSK pool setup and XDP BPF program setup are separate actions. XSK pool setup can be done without any XDP BPF program. The XDP BPF program can be added, removed or changed without any reconfiguration of the XSK pool. Test results with A53 1.2GHz: xdpsock rxdrop copy mode, 64 byte frames: pps pkts 1.00 rx 856,054 10,625,775 Two CPUs with both 100% utilization. xdpsock rxdrop zero-copy mode, 64 byte frames: pps pkts 1.00 rx 889,388 4,615,284 Two CPUs with 100% and 20% utilization. Packet rate increases and CPU utilization is reduced. 100% CPU load seems to the base load. This load is consumed by ksoftirqd just for dropping the generated packets without xdpsock running. Using batch API reduced CPU utilization slightly, but measurements are not stable enough to provide meaningful numbers.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull user work thread updates from Christian Brauner: "This contains the work generalizing the ability to create a kernel worker from a userspace process. Such user workers will run with the same credentials as the userspace process they were created from providing stronger security and accounting guarantees than the traditional override_creds() approach ever could've hoped for. The original work was heavily based and optimzed for the needs of io_uring which was the first user. However, as it quickly turned out the ability to create user workers inherting properties from a userspace process is generally useful. The vhost subsystem currently creates workers using the kthread api. The consequences of using the kthread api are that RLIMITs don't work correctly as they are inherited from khtreadd. This leads to bugs where more workers are created than would be allowed by the RLIMITs of the userspace process in lieu of which workers are created. Problems like this disappear with user workers created from the userspace processes for which they perform the work. In addition, providing this api allows vhost to remove additional complexity. For example, cgroup and mm sharing will just work out of the box with user workers based on the relevant userspace process instead of manually ensuring the correct cgroup and mm contexts are used. So the vhost subsystem should simply be made to use the same mechanism as io_uring. To this end the original mechanism used for create_io_thread() is generalized into user workers: - Introduce PF_USER_WORKER as a generic indicator that a given task is a user worker, i.e., a kernel task that was created from a userspace process. Now a PF_IO_WORKER thread is just a specialized version of PF_USER_WORKER. So io_uring io workers raise both flags. - Make copy_process() available to core kernel code - Extend struct kernel_clone_args with the following bitfields allowing to indicate to copy_process(): - to create a user worker (raise PF_USER_WORKER) - to not inherit any files from the userspace process - to ignore signals After all generic changes are in place the vhost subsystem implements a new dedicated vhost api based on user workers. Finally, vhost is switched to rely on the new api moving it off of kthreads.

Merge my x86 user copy updates branch. This cleans up a lot of our x86 memory copy code, particularly for user accesses. I've been pushing for microarchitectural support for good memory copying and clearing for a long while, and it's been visible in how the kernel has aggressively used 'rep movs' and 'rep stos' whenever possible. And that micro-architectural support has been improving over the years, to the point where on modern CPU's the best option for a memory copy that would become a function call (as opposed to being something that can just be turned into individual 'mov' instructions) is now to inline the string instruction sequence instead. However, that only makes sense when we have the modern markers for this: the x86 FSRM and FSRS capabilities ("Fast Short REP MOVS/STOS"). So this cleans up a lot of our historical code, gets rid of the legacy marker use ("REP_GOOD" and "ERMS") from the memcpy/memset cases, and replaces it with that modern reality. Note that REP_GOOD and ERMS end up still being used by the known large cases (ie page copyin gand clearing). The reason much of this ends up being about user memory accesses is that the normal in-kernel cases are done by the compiler (__builtin_memcpy() and __builtin_memset()) and getting to the point where we can use our instruction rewriting to inline those to be string instructions will need some compiler support. In contrast, the user accessor functions are all entirely controlled by the kernel code, so we can change those arbitrarily. Thanks to Borislav Petkov for feedback on the series, and Jens testing some of this on micro-architectures I didn't personally have access to. * x86-rep-insns: x86: rewrite '__copy_user_nocache' function x86: remove 'zerorest' argument from __copy_user_nocache() x86: set FSRS automatically on AMD CPUs that have FSRM x86: improve on the non-rep 'copy_user' function x86: improve on the non-rep 'clear_user' function x86: inline the 'rep movs' in user copies for the FSRM case x86: move stac/clac from user copy routines into callers x86: don't use REP_GOOD or ERMS for user memory clearing x86: don't use REP_GOOD or ERMS for user memory copies x86: don't use REP_GOOD or ERMS for small memory clearing x86: don't use REP_GOOD or ERMS for small memory copies

2023-04-24tpm_tis: fix stall after iowrite*()sHaris Okanovic
ioread8() operations to TPM MMIO addresses can stall the CPU when immediately following a sequence of iowrite*()'s to the same region. For example, cyclitest measures ~400us latency spikes when a non-RT usermode application communicates with an SPI-based TPM chip (Intel Atom E3940 system, PREEMPT_RT kernel). The spikes are caused by a stalling ioread8() operation following a sequence of 30+ iowrite8()s to the same address. I believe this happens because the write sequence is buffered (in CPU or somewhere along the bus), and gets flushed on the first LOAD instruction (ioread*()) that follows. The enclosed change appears to fix this issue: read the TPM chip's access register (status code) after every iowrite*() operation to amortize the cost of flushing data to chip across multiple instructions.

2023-04-24tpm/tpm_tis_synquacer: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
