[PATCH net-next v3 0/4] net: devmem: allow rx-buf-size > PAGE_SIZE per binding

by Bobby Eshleman

Every devmem dmabuf binding hands the page_pool PAGE_SIZE niovs today. On NICs that consume one descriptor per netmem, this caps a single RX descriptor at PAGE_SIZE and burns CPU on buffer churn. In this series, we add a bind-time netlink attribute, NETDEV_A_DMABUF_RX_BUF_SIZE, that lets userspace request a larger niov size (power of two >= PAGE_SIZE). Drivers must opt in via queue_mgmt_ops.QCFG_RX_PAGE_SIZE. Selftests use udmabuf, but udmabuf sgtables were previously hardcoded to PAGE_SIZE. This series modifies udmabuf to respect folio sizes in its exported sgtable. The result is that when backing udmabuf with MFD_HUGETLB 2MB pages, the sgtable is populated with 2MB entries, allowing devmem's gen_pool to carve out large (eg. 64K) niovs. Measurements ------------ Setup: kperf devmem RX/TX cuda, 4 flows, 64 MB messages, 60s, dctcp, num-rx-queues=4, dmabuf-rx/tx-size-mb=2048, 10 runs per niov size, mlx5. niov RX dev Gbps RX flow avg Gbps app sys % ----- ---------------- ----------------- ---------------- 4K 300.63 +/- 53.21 75.16 +/- 13.30 54.15 +/- 10.23 16K 321.35 +/- 28.20 80.34 +/- 7.05 41.05 +/- 8.87 32K 347.63 +/- 2.20 86.91 +/- 0.55 44.54 +/- 3.51 64K 332.11 +/- 14.26 83.03 +/- 3.56 35.47 +/- 3.11 RX app sys % drops ~19% from 4K to 64K. kperf support (not yet merged): https://github.com/facebookexperimental/kperf/commit/8837577f920876bce6986e… Signed-off-by: Bobby Eshleman <bobbyeshleman(a)meta.com> --- Changes in v3: - fix a bunch of non-reverse christmas tree declarations (Stan) - remove extra uint32 cast for getpagesize() (Stan) - remove overzealous strtoul checking (Stan) - remove value checks that the kernel already performs on rx_buf_size (Stan) - Link to v2: https://lore.kernel.org/r/20260611-tcpdm-large-niovs-v2-0-ee2bf15e7523@meta… Changes in v2: - Use NL_SET_ERR_MSG_FMT for sg alignment failure details (Stan) - Keep -E2BIG (not a direct ask, but seemed preferred, Stan) - Update udmabuf commit message and comments explaining why "one sg ent per folio" is useful (Christian) - Set/restore nr_hugepages in py harness (Stan) - Link to v1: https://lore.kernel.org/r/20260603-tcpdm-large-niovs-v1-0-f37a4ac6726c@meta… --- Bobby Eshleman (4): net: devmem: allow rx-buf-size > PAGE_SIZE per dmabuf binding udmabuf: emit one sg entry per pinned folio selftests/net: ncdevmem: add -b option to set rx-buf-size on bind selftests/net: devmem.py: add check_rx_large_niov Documentation/netlink/specs/netdev.yaml | 8 +++ drivers/dma-buf/udmabuf.c | 52 +++++++++++++++++-- include/uapi/linux/netdev.h | 1 + net/core/devmem.c | 51 +++++++++++-------- net/core/devmem.h | 13 +++-- net/core/netdev-genl-gen.c | 5 +- net/core/netdev-genl.c | 19 ++++++- tools/include/uapi/linux/netdev.h | 1 + tools/testing/selftests/drivers/net/hw/config | 1 + tools/testing/selftests/drivers/net/hw/devmem.py | 12 ++++- .../testing/selftests/drivers/net/hw/devmem_lib.py | 58 +++++++++++++++++++++- tools/testing/selftests/drivers/net/hw/ncdevmem.c | 36 ++++++++++++-- .../testing/selftests/drivers/net/hw/nk_devmem.py | 11 +++- 13 files changed, 225 insertions(+), 43 deletions(-) --- base-commit: 518d8d0199538a4d6d5e51064044ece71e0c42e7 change-id: 20260602-tcpdm-large-niovs-56523a3a1077 Best regards, -- Bobby Eshleman <bobbyeshleman(a)meta.com>

What Makes the Foodle Game Name So Interesting?

by lousmagic0＠gmail.com

At first glance, the Foodle game name feels like it was designed for fun-loving Gen Z players who enjoy casual gaming with a side of chaos. The concept is simple: guess food-related words within limited attempts. Easy, right? That’s exactly what it wants you to think. The complexity kicks in when you realize your brain suddenly forgets every food you’ve ever eaten. Seriously, under pressure, “burger” becomes “burder,” and “noodle” starts looking like it belongs in a physics textbook. https://food-le.com The genius behind the Foodle game name lies in its deceptive simplicity. Unlike traditional word games, it adds a flavorful twist—literally forcing you to think in categories like snacks, dishes, ingredients, and sometimes even weird culinary terms you’ve only seen on cooking shows at 3 a.m.

A Guide to the Thrills of Drift Hunters

by tylerwire＠web-library.net

Have you ever dreamt of effortlessly sliding a high-performance car around a corner, smoke billowing from the tires, and the roar of the engine echoing in your ears? While real-life drifting requires significant skill, dedication, and a rather large budget, the world of online gaming offers a fantastic, accessible alternative. Today, we're diving into an exhilarating example: Drift Hunters, a game that lets you experience the pure joy of controlled chaos on four wheels. What is Drift Hunters and Why Should You Play? Drift Hunters is a browser-based drifting game that, despite its simplicity, delivers an incredibly satisfying and addictive experience. Forget complex storylines or elaborate character progression; this game is all about the art of the drift. You'll choose from a roster of customizable cars, hit the track, and focus solely on chaining together epic drifts to earn points and upgrade your ride. https://drifthuntersfree.com The beauty of games like Drift Hunters lies in their immediacy. There’s no lengthy download, no expensive console required. You can simply open your browser, navigate to the game, and within seconds, you're behind the wheel, ready to lay down some serious rubber. It's the perfect pick-up-and-play title for a quick adrenaline fix, a stress-relieving session, or simply to hone your virtual drifting skills. Getting Started: Your First Slide The controls in Drift Hunters are refreshingly straightforward, making it easy for newcomers to jump right in. Typically, you'll use the W, A, S, D keys for acceleration, turning, and braking, with the spacebar often serving as your handbrake – a crucial tool for initiating those perfect drifts. When you first load the game, you'll likely start with a basic car and a simple track. Don't be discouraged if your initial attempts at drifting resemble a drunken penguin on ice. The key is practice and understanding the mechanics. Here’s a general approach to initiating a drift: Build Speed: Accelerate to a decent speed before approaching a corner. Initiate with a Tap: Just before entering the turn, briefly tap the handbrake while simultaneously turning into the corner. Counter-Steer and Throttle Control: As the car begins to slide, you'll need to counter-steer (turn the wheel in the opposite direction of the slide) and feather the throttle. This is where the "art" comes in. Too much throttle, and you'll spin out; too little, and you'll straighten up. Maintain and Exit: Keep the slide going by balancing counter-steering and throttle, guiding your car through the corner. As you exit, gradually straighten the wheel and apply more throttle to regain control. The goal is to maintain the drift for as long as possible, keeping your car at a good angle and avoiding hitting the walls. Longer, smoother drifts earn you more points, which in turn means more money to spend on upgrades. You can find the game and start your journey at https://drifthuntersfree.com. Mastering the Art: Tips for Becoming a Drift King Once you've got the basics down, here are some tips to elevate your Drift Hunters game: Practice Makes Perfect: This cannot be stressed enough. Each car handles differently, and each track presents unique challenges. Spend time on different maps, experimenting with various approaches to corners. Upgrade Strategically: Early on, focus on upgrading your engine for more power and your tires for better grip (or lack thereof, depending on your drift style!). Later, you can fine-tune suspension and weight distribution. Experiment with Camera Angles: Some players find it easier to drift with a third-person view, while others prefer a more immersive in-car perspective. Find what works best for you. Listen to Your Engine: The sound of your engine can provide crucial feedback. Learn to recognize when you're about to spin out or when you're losing momentum. Don't Be Afraid to Fail: Spinning out is part of the learning process. Embrace it, learn from your mistakes, and try again. Handbrake is Your Friend: While tempting to rely solely on power slides, the handbrake is invaluable for precise drift initiation and adjusting your angle mid-drift. Watch the Pros (if available): If you can find videos of experienced Drift Hunters players, pay attention to their lines, their throttle control, and how they manage their drifts. Conclusion: Embrace the Slide Drift Hunters offers a fantastic opportunity to experience the thrill of drifting without the real-world consequences. It's a game that rewards practice, precision, and a bit of daring. Whether you're looking for a quick five-minute break or an extended session of rubber-burning fun, this game delivers. So, fire up your browser, pick your dream drift machine, and prepare to unleash your inner petrolhead. The asphalt awaits your tire marks!
