[RFC PATCH 2/7] virtio: use pr_debug_ratelimited to avoid flooding

by Jim Cromie

When I test dynamic-debug's static-key toggling performance in a virtme-ng session, it is too easy to create an enormous flood of printks to the console. #> echo +p > /proc/dynamic_debug/control #> echo -p > /proc/dynamic_debug/control Now theres no "good reason" to shoot your own foot, but this is also easy to fix, by ratelimiting the sources of the flood. I don't think theres a loss of utility to virtio. Example console output is below the snip. For this test-case, ratelimiting suppresses >900k callbacks. It also allows this simple load test for the static-key toggling performance in a following patch.

[PATCH v2 0/6] dma-buf: heaps: add coherent reserved-memory heap

by Albert Esteve

This patch introduces a new heap driver to expose DT non‑reusable "shared-dma-pool" coherent regions as dma-buf heaps, so userspace can allocate buffers from each reserved, named region. Because these regions are device‑dependent, each heap instance binds a heap device to its reserved‑mem region via a newly introduced helper function -namely, of_reserved_mem_device_init_with_mem()- so coherent allocations use the correct dev->dma_mem. Charging to cgroups for these buffers is intentionally left out to keep review focused on the new heap; I plan to follow up based on Eric’s [1] and Maxime’s [2] work on dmem charging from userspace. This series also makes the new heap driver modular, in line with the CMA heap change in [3].

[PATCH v2 000/110] vfs: change inode->i_ino from unsigned long to u64

by Jeff Layton

This version splits the change up to be more bisectable. It first adds a new kino_t typedef and a new "PRIino" macro to hold the width specifier for format strings. The conversion is done, and then everything is changed to remove the new macro and typedef. I also missed a few places in the earlier set. This one hopefully does a bit more thorough job. My thanks and apologies to everyone who sent R-b/A-b for the v1 series. v2 breaks a lot of the changes up into two patches so many of those didn't carry over. Please resend those if you're still OK with it. The entire pile is in the "iino-u64" branch of my tree, if anyone is interested in testing this: https://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux.git/ Original cover letter follows: ----------------------8<----------------------- Christian said [1] to "just do it" when I proposed this, so here we are! For historical reasons, the inode->i_ino field is an unsigned long, which means that it's 32 bits on 32 bit architectures. This has caused a number of filesystems to implement hacks to hash a 64-bit identifier into a 32-bit field, and deprives us of a universal identifier field for an inode. This patchset changes the inode->i_ino field from an unsigned long to a u64. This shouldn't make any material difference on 64-bit hosts, but 32-bit hosts will see struct inode grow by at least 4 bytes. This could have effects on slabcache sizes and field alignment. The bulk of the changes are to format strings and tracepoints, since the kernel itself doesn't care that much about the i_ino field. The first patch changes some vfs function arguments, so check that one out carefully. With this change, we may be able to shrink some inode structures. For instance, struct nfs_inode has a fileid field that holds the 64-bit inode number. With this set of changes, that field could be eliminated. I'd rather leave that sort of cleanups for later just to keep this simple. Much of this set was generated by LLM, but I attributed it to myself since I consider this to be in the "menial tasks" category of LLM usage.

[PATCH 0/9] accel: New driver for NXP's Neutron NPU

by Ioana Ciocoi-Radulescu

Introduce a new accel driver for the Neutron Neural Processing Unit (NPU), along with associated dt-bindings and DTS node. The first patch extends the GEM DMA helper APIs to allow bidirectional mapping of non-coherent DMA buffers. While not part of the Neutron driver, it's a prerequisite allowing us to use the GEM DMA helper. Neutron is a Neural Processing Unit from NXP, providing machine learning (ML) acceleration for edge AI applications. Neutron is integrated on NXP SoCs such as the i.MX95. The NPU consists of the following: - RISC-V core running a proprietary firmware - One or more Neutron cores, representing the main computation engine performing ML operations - Dedicated fast memory (TCM) - DMA engine that handles data transfers between DDR and TCM The firmware is closed source and distributed as a binary here [1]. The Neutron software stack also contains a userspace library [1] and a LiteRT custom delegate [2] that allow integration with standard LiteRT tools.

Hi, The recent introduction of heaps in the optee driver [1] made possible the creation of heaps as modules. It's generally a good idea if possible, including for the already existing system and CMA heaps. The system one is pretty trivial, the CMA one is a bit more involved, especially since we have a call from kernel/dma/contiguous.c to the CMA heap code. This was solved by turning the logic around and making the CMA heap call into the contiguous DMA code. Let me know what you think, Maxime 1: https://lore.kernel.org/dri-devel/20250911135007.1275833-4-jens.wiklander@l… Signed-off-by: Maxime Ripard <mripard(a)kernel.org> --- Changes in v2: - Collect tags - Don't export dma_contiguous_default_area anymore, but export dev_get_cma_area instead - Mentioned that heap modules can't be removed - Link to v1: https://lore.kernel.org/r/20260225-dma-buf-heaps-as-modules-v1-0-2109225a09… --- Maxime Ripard (9): dma: contiguous: Turn heap registration logic around dma: contiguous: Make dev_get_cma_area() a proper function dma: contiguous: Make dma_contiguous_default_area static mm: cma: Export dev_get_cma_area() mm: cma: Export cma_alloc and cma_release mm: cma: Export cma_get_name dma-buf: heaps: Export mem_accounting parameter dma-buf: heaps: cma: Turn the heap into a module dma-buf: heaps: system: Turn the heap into a module drivers/dma-buf/dma-heap.c | 1 + drivers/dma-buf/heaps/Kconfig | 4 ++-- drivers/dma-buf/heaps/cma_heap.c | 21 +++++---------------- drivers/dma-buf/heaps/system_heap.c | 5 +++++ include/linux/dma-map-ops.h | 14 ++++++-------- kernel/dma/contiguous.c | 37 ++++++++++++++++++++++++++++++++++--- mm/cma.c | 3 +++ 7 files changed, 56 insertions(+), 29 deletions(-) --- base-commit: 499a718536dc0e1c1d1b6211847207d58acd9916 change-id: 20260225-dma-buf-heaps-as-modules-1034b3ec9f2a Best regards, -- Maxime Ripard <mripard(a)kernel.org>
