[PATCH v17 0/6] Rust bindings for gem shmem

by Lyude Paul

Most of this patch series has already been pushed upstream, this is just the second half of the patch series that has not been pushed yet + some additional changes which were required to implement changes requested by the mailing list. This patch series is originally from Asahi, previously posted by Daniel Almeida. The previous version of the patch series can be found here: https://patchwork.freedesktop.org/series/164580/ Branch with patches applied available here: https://gitlab.freedesktop.org/lyudess/linux/-/commits/rust/gem-shmem This patch series applies on top of drm-rust-next Patch-series wide changes since V15: * Fix some major rebasing errors I somehow didn't notice :( * Drop the dependency on LazyInit, use the trick that Alice suggested instead. * Fix dependency ordering so that Tyr can get the vmap stuff first without the other bits. Patch-series wide changes since V16: * Fix ordering one more time (SetOnce::reset() doesn't need to come before adding vmap functions) * Rebase against the latest DeviceContext changes from me that got pushed.

by careful.earthworm.usil＠hidingmail.com

Feeling the need for speed and a bit of winter fun, even when the weather outside is frightful? Then maybe it’s time to check out Snow Rider 3D. This simple but surprisingly addictive game offers a thrill of downhill skiing and snowboarding right from your browser, no downloads required. Let’s break down how to jump in and start enjoying this surprisingly engaging title. https://snowriderfree.com/ Gameplay: Simple Controls, Endless Possibilities The core gameplay of Snow Rider 3D is deceptively straightforward. You control your character's direction using the left and right arrow keys (or A and D). Your objective? Navigate through a series of procedurally generated slopes littered with obstacles. These obstacles range from simple ramps and rails to more challenging hazards like trees, snowdrifts, and even abandoned shacks. The beauty of Snow Rider 3D lies in its physics. While simple, they feel surprisingly realistic. You'll need to anticipate turns, adjust your speed, and time your jumps to successfully navigate the terrain. A crash will reset you to the beginning of the course, so precision and patience are key. The game offers different levels, each presenting a unique challenge. Some focus on speed and long jumps, while others demand skillful maneuvering through tight spaces. As you progress, you unlock new skins and sleds, adding a touch of customization to your experience. Think of it as a casual time-killer that can quickly turn into an hour-long obsession! Tips for Mastering the Mountain: Alright, so you're ready to hit the slopes. Here are a few tips to help you improve your runs and avoid those frustrating wipeouts: Practice Makes Perfect: Don't get discouraged by early crashes. The more you play, the better you'll understand the physics and learn to anticipate the terrain. Master the Turns: Smooth, controlled turns are essential for maintaining speed and avoiding obstacles. Practice feathering the arrow keys to make subtle adjustments. Timing is Everything: When approaching jumps and ramps, pay close attention to your speed and angle. A well-timed jump can make all the difference. Don't Be Afraid to Slow Down: Sometimes, the fastest route isn't the safest. Don't be afraid to ease off the gas and navigate tricky sections with caution. Consider looking up guides for specific levels of Snow Rider 3D at websites like Snow Rider 3D if you’re really struggling. Experiment with Sleds and Skins: Different sleds may offer slight variations in handling. Try out different options to find one that suits your playstyle. Conclusion: A Fun and Accessible Winter Escape Snow Rider 3D is a surprisingly addictive and accessible game that’s perfect for a quick dose of winter fun. It's simple controls and challenging gameplay make it easy to pick up and play, while its procedural generation ensures that each run is a unique experience.

Unlocking Wordplay: A Guide to the Connections Game

by profound.cheetah.kect＠hidingmail.net

In a world brimming with complex video games and immersive online experiences, sometimes the most satisfying entertainment comes from a simple yet brilliant word puzzle. The Connections Game, a daily online brain-teaser, offers just that – a delightful challenge that tests your vocabulary, logic, and lateral thinking. If you’re looking for a fresh way to engage your mind and expand your word association skills, then stepping into the world of Connections Game is a fantastic choice. https://connectionsgamefree.com What is Connections Game? At its heart, Connections is a game about finding hidden relationships between words. Each day, you're presented with 16 seemingly disparate words. Your task is to group these words into four sets of four, with each set sharing a common thread or category. The categories can be anything from "Types of Fruit" to "Words that Rhyme with 'Blue'" or even more abstract connections that require a bit of outside-the-box thinking. The beauty of the game lies in its simplicity and the sheer satisfaction of uncovering those clever links. You can experience it firsthand at Connections Game. The Gameplay Unpacked When you open the game, you'll see all 16 words laid out before you. To play, you simply click on four words you believe belong together. Once you’ve selected your quartet, you hit the "Submit" button. Correct Guess: If your four words form a valid category, they will disappear, and the category will be revealed. You'll then move on to the remaining words. Incorrect Guess: If your guess is wrong, the words will remain on the board, and you'll lose one of your four allowed mistakes. That's right – you only get four incorrect attempts before the game ends! This adds a delicious layer of pressure and strategic thinking. The categories are color-coded, ranging from "Yellow" (easiest) to "Purple" (most difficult/obscure). Often, the trickiest part is recognizing "red herrings" – words that seem to fit into multiple categories, making you second-guess your initial assumptions. Tips for Success To truly master the Connections Game, here are a few friendly tips: Read All the Words First: Before clicking anything, take a moment to scan all 16 words. Look for obvious groupings first. Are there any four words that immediately jump out as being related? Look for Obvious Categories: Sometimes, one or two categories will be relatively straightforward. Tackling these first can clear up the board and make the remaining words easier to analyze. Consider Different Meanings: Many words have multiple meanings. Don't get stuck on just one interpretation. For example, "bat" could refer to a flying mammal or a piece of sports equipment. Think About Wordplay and Sounds: Categories aren't always about literal definitions. They can involve synonyms, antonyms, rhyming words, or even words that form a phrase when combined. Utilize Your Mistakes Wisely: Remember, you only have four chances. If you’re unsure, it’s often better to hold off on a guess until you have a stronger conviction. Sometimes, eliminating other categories can clarify ambiguous words. Don't Be Afraid to Rearrange: Mentally (or even physically, if you're playing on a device that allows it) rearrange the words. Seeing them in a different order can sometimes spark new connections. Conclusion The Connections Game is more than just a pastime; it's a daily brain workout that's both challenging and incredibly rewarding. It encourages you to think critically, expand your vocabulary, and see the intricate relationships between words. Whether you're a seasoned wordsmith or just looking for a fun new way to pass the time, give it a try – you might just find your new favorite daily ritual! You can access the game daily at Connections Game.

Wordle Unlimited Guide for Endless Word Puzzle Fun

by disastrous.heron.yxfs＠hidingmail.net

Introduction to Wordle Unlimited Experience Wordle Unlimited is a modern word puzzle game designed for players who enjoy continuous vocabulary challenges without daily limits. Unlike traditional word guessing games that restrict attempts to once per day, this version allows unlimited gameplay sessions. This creates an environment where learning, practice, and entertainment can happen at any time. https://wordleunlimitedgame.org/ The game has become popular among language learners, puzzle fans, and casual gamers because it combines simple rules with strategic thinking. Players must guess a hidden word within a set number of attempts, using feedback from each guess to improve accuracy. The unlimited format removes waiting time and allows repeated practice, making it suitable for skill development and relaxation. What Wordle Unlimited Means in Modern Gaming Wordle Unlimited refers to an expanded version of the original word guessing concept where users can play repeatedly without restriction. Each round generates a new hidden word, giving continuous opportunities to test vocabulary knowledge. This format is especially useful for users who want to improve language skills. Instead of waiting for a daily puzzle, players can engage in multiple rounds in one sitting. The structure remains consistent, which helps build familiarity and confidence over time. The game typically uses a grid system where each attempt reveals color coded feedback. Correct letters in correct positions, correct letters in wrong positions, and incorrect letters are all highlighted differently to guide future guesses. How to Play Wordle Unlimited Step by Step Playing Wordle Unlimited is straightforward and accessible for all skill levels. The objective is to identify the hidden word within a limited number of guesses. First, the player enters a starting word. This word is usually chosen to include common vowels and consonants to maximize information. After submission, the game provides feedback on each letter. Next, the player analyzes the feedback and adjusts the next guess accordingly. Letters that are correct and correctly placed should be kept in the same position. Letters that are correct but misplaced should be repositioned in the next attempt. Letters that are not part of the word should be avoided. This process continues until the correct word is discovered or attempts are exhausted. After each round, a new word is available immediately, allowing continuous play. Key Features That Define Wordle Unlimited Wordle Unlimited includes several features that make it appealing to a wide audience. One major feature is unlimited gameplay, which removes daily restrictions and supports continuous learning. Another important feature is instant feedback after each guess. This feedback system helps players improve logic and vocabulary skills quickly. It also encourages strategic thinking rather than random guessing. The game also maintains a simple interface, making it easy to understand for beginners. There are no complex controls or instructions, which allows users to focus entirely on word solving. Additionally, the game supports replayability. Each new round offers a different word challenge, which keeps the experience fresh and engaging over long periods. Effective Strategies for Better Results Success in Wordle Unlimited often depends on strategy rather than luck. One effective approach is starting with words that include multiple vowels and common consonants. This helps identify useful letters early in the game. Another strategy is pattern recognition. After receiving feedback, players should focus on common English word structures. Recognizing prefixes, suffixes, and common letter combinations can significantly improve guessing accuracy. It is also helpful to avoid repeating incorrect letters. Keeping track of eliminated letters reduces unnecessary guesses and increases efficiency. Advanced players often use logical elimination methods. By narrowing down possibilities step by step, they can solve puzzles in fewer attempts and improve overall performance. Benefits of Playing Wordle Unlimited Regularly Wordle Unlimited offers several cognitive and educational benefits. One major benefit is vocabulary improvement. Regular exposure to new words helps expand language knowledge over time. The game also enhances problem solving skills. Each round requires analysis, deduction, and logical thinking. These mental exercises contribute to sharper cognitive abilities. Another benefit is stress relief. The simple and repetitive structure of the game provides a relaxing experience that can help reduce mental fatigue. In addition, unlimited access allows flexible practice schedules. Players can engage for a few minutes or extended sessions depending on personal preference, making it suitable for different lifestyles. Why Wordle Unlimited Has Become So Popular The popularity of Wordle Unlimited comes from its balance of simplicity and challenge. It is easy to learn but difficult to master, which keeps users engaged. Social sharing also plays a role in its growth. Many players enjoy comparing results and discussing strategies with others, creating a sense of community around the game. The unlimited format is another key factor. Unlike limited daily puzzles, this version allows continuous engagement, which appeals to users who enjoy long gaming sessions. Its accessibility across devices also contributes to popularity. Players can enjoy the game on computers, tablets, or mobile devices without complicated setup processes. Conclusion on Wordle Unlimited Value Wordle Unlimited stands out as an engaging and educational word puzzle experience that combines entertainment with cognitive development. Its unlimited format allows continuous learning and practice, making it suitable for both beginners and advanced players. With simple rules, strategic depth, and instant feedback, the game provides a balanced experience that supports vocabulary growth and logical thinking. Whether used for relaxation or skill improvement, Wordle Unlimited remains a strong choice for anyone interested in word based challenges.

[PATCH v5] dma-buf: Fix silent overflow for phys vec to sgt

by David Hu

In case MMIO size is bigger than 4G and peer2peer DMA goes through host bridge, we trigger a code path that assigns the total linked IOVA (which is greater than 4G) to mapped_len. Previously, `mapped_len` was declared as 32-bit `unsigned int`. When accumulating `size_t` lengths, this leads to a silent wrap-around. This truncation causes truncated lengths to be passed to functions like `fill_sg_entry()`. Fix this by changing `mapped_len` to `size_t` (64-bit). While at it, fix similar potential overflow issues in `calc_sg_nents` by using `size_t` for `nents` and checking against `UINT_MAX` and using `unsigned int` for the loop iterator in `fill_sg_entry` to match. Fixes: 3aa31a8bb11e ("dma-buf: provide phys_vec to scatter-gather mapping routine") Cc: stable(a)vger.kernel.org Cc: iommu(a)lists.linux.dev Reviewed-by: Pranjal Shrivastava <praan(a)google.com> Signed-off-by: David Hu <xuehaohu(a)google.com> --- Changes in v5: - Removed WARN_ON_ONCE from calc_sg_nents() to avoid log noise (Jason). - Added explicit check for `!nents` in dma_buf_phys_vec_to_sgt() to cleanly return -EINVAL on overflow (Jason).

Changes in v3: - Removed leftover sentence fragment from the commit message. - Kept `nents = 0` initialization (previously stated as removed in the v2 changelog) as it is strictly required for the `+=` accumulation loop in `calc_sg_nents()`.
