I thought the general design was the bars were made inaccessible before going to a low power state, and remain inaccessible while it is in low power? So the order of D0 doesn't matter. If it is not in D0 then there is no mappings and zap/revoke is a NOP. If is it in D0 then it doesn't matter because D0 is a nop. Jason

[PATCH] base: Remove unused DMA_FENCE_TRACE Kconfig symbol

by Geert Uytterhoeven

Commit d72277b6c37db66b ("dma-buf: nuke DMA_FENCE_TRACE macros v2") in v5.16 removed all users of DMA_FENCE_TRACE on the premise that the Kconfig symbol did not exist. Apparently one failed to notice the symbol did exist since almost five years before: it was renamed from FENCE_TRACE to DMA_FENCE_TRACE in commit f54d1867005c3323 ("dma-buf: Rename struct fence to dma_fence") in v4.10. Time passed by, so remove the Kconfig symbol, as no one seems to have missed the functionality.

[PATCH v3 0/4] rust / dma_buf: Add abstractions for dma_fence

by Philipp Stanner

Changes since v2: - Don't drop DriverFenceData as a whole, but only the members we really want to drop. Gives more robustness. (Gary). - Break apart large pin_init_from_closure(). (Danilo, Onur) - Remove rcu_barrier() and synchronize_rcu() from FenceCtx::drop(). FenceCtx might drop in atomic context, where you must not perform those operations. With the current way C dma_fence is designed, the driver must wait for a grace period manually until it unloads. - Repair the DriverFenceBorrow implementation, properly injecting a life time into it. (Danilo) - Fix memory layout bug for rcu_head. (Onur) - Drop RCU patches, since this series doesn't need them anymore. Changes since v1: - Remove unnecessary mutable references (Alice) - Split up unsafe comments where possible (Danilo) - Remove PhantomData + implement FenceCtx ops trait (Boris) - Consistently call FenceCtx generic data `T`. FenceDataType is derived from that. (Boris) - Add abstractions for call_rcu() and synchronize_rcu() (Danilo) - Add ECANCELED error code in Rust (Alice) - Remove the rcu_barrier() from FenceCtx::drop() – because we now use call_rcu(), there can be no UAF access to the FenceCtx anymore. In any case, it is illegal to use either call_rcu() or synchronize_rcu() in FenceCtx::drop(), because our new drop_driver_fence_data() can run in atomic context and might put the last fence_ctx reference. So we now only have to guard against module unload, which it seems either the driver or Rust driver-core / module unload infrastructure must solve. - Minor formatting etc. changes - Add C helpers to MAINTAINERS. (Danilo) - Ensure that `Fence::is_signaled()` is fully synchronized, i.e., all callbacks really have run. See [1] and [2]. (Myself, Christian König) Changes since the RFCs: - Include support for ForeignOwnable for ARef, so that a Fence can be stuffed into an XArray et al. (Code by Danilo) - Implement ForeignOwnable (with new borrow type) for DriverFence, so that it can be stuffed into an XArray. - Include the rcu::RcuBox data type to defer dropping data with RCU (Cody by Alice) - Port DmaFence to RcuBox to make UAF bugs through later, new dma_fence callbacks (backend_ops) impossible. - Force users to pass their fence data in an RcuBox (or have it not need drop()) through a Sealed trait. - Document the rules for the user's DriverFence::data's drop implementation very clearly (deadlock danger). - rustfmt, Clippy. - Various style suggestions, safety comments, etc. (Önur) - Add __rust_helper prefix to helper functions. (Önur) Changes in RFC v3: - Omit JobQueue patches for now - Completely redesign the memory layout: Instead of a Fence refcounting a DriverFence, both now live in the same allocation to allow for future support the dma_fence backend_ops callbacks which need to do container_of. (mostly Boris's feedback) - Allow for pre-allocating fences to avoid deadlocks when submitting jobs to a GPU. (Boris) - Simultaneously, allow for pre-preparing fence callback objects, so the driver can allocate them when it sees fit. (code largely stolen and inspired by Daniel). - Signal fences on drop, ensure synchronization. - Force users to set an error code when signalling. - Write more documentation - A ton of minor other changes. [1] https://lore.kernel.org/dri-devel/20260608142436.265820-2-phasta@kernel.org/ [2] https://lore.kernel.org/dri-devel/20260612104251.2264707-2-phasta@kernel.or… Alright, so since the last RFCs did not reveal significant design issues, I decided to transition this series to a v1 and hope that we can get it upstream. This now includes code for more common infrastructure that dma_fence needs, contributed by Danilo and Alice. --- Old cover letter for RFC: So, this is the spiritual successor of the first / second RFC [1]. v2 also contained code for drm::JobQueue, but mostly to show how the fence code would be used. JobQueue is under heavy rework right now, so I don't want to bother your eyes with it. The docstring examples should show how Rust fences are supposed to be used, though. This v3 contains a huge amount of highly valuable feedback from a variety of people, notably Boris, but also from Alice, Gary and Danilo. There are some TODOs open (a better trait for fence backend_ops and RCU support), but my hope is that this effort is now finally approaching its end. I would greatly appreciate feedback and especially more information about what might be missing to make this usable, which is obviously where Daniel's and Boris's feedback will be valuable once more. Please regard this patch just as what it's titled: an RFC, to discuss a bit more and to inform a broader community about what the current state is and where this is heading at.

Living a Thousand Lives: Exploring the Quirky World of BitLife

by vast.stoat.yach＠hidingmail.net

Have you ever wondered what your life would look like if you made entirely different choices? Life simulation games have always been a fascinating genre for gamers, but few capture the unpredictable, hilarious, and sometimes chaotic nature of existence quite like Bitlife. Instead of relying on heavy 3D graphics, it is a text-based simulator that focuses entirely on the ripple effects of your decisions. It’s perfect for casual gaming sessions, so let's dive into how to play and get the most out of this quirky experience. https://bitlifefree.io/ Gameplay: Growing Up, One Year at a Time The premise of the game is incredibly simple but highly addictive. You are born with a random set of basic stats—Happiness, Health, Smarts, and Looks—in a random country to random parents. From there, you control your character's life year by year simply by tapping the "Age" button. In your early years, your choices are understandably limited to things like interacting with your parents, going to the doctor, or playing with pets. But as you grow into a teenager and an adult, the world completely opens up. You can choose to study hard, drop out, date, travel the world, buy real estate, or even turn to a life of crime. Every year, the game throws random scenarios at you: a classmate might insult you, you might be offered a questionable substance at a party, or you might find a wallet on the street. How you react directly impacts your stats and future opportunities. You might even have to pass mini-games, like navigating a maze for your driving test or escaping from prison. The ultimate goal is simply to live your life until your character passes away, leaving behind a unique legacy and a tombstone summarizing your deeds. Tips for a Great Experience If you are just starting out, here are a few tips to make your virtual life more successful—or at least more entertaining: Keep an eye on your core stats: Your Health and Happiness are crucial. If they drop too low, your character might face early health issues. Go to the gym, meditate, go to the movies, or spend time with family to keep these bars in the green. Education pays off (usually): If you want a high-paying, stable career like a doctor, judge, or CEO, use the "Study harder" option every year during school. Read books at the library to passively boost your Smarts stat. Hunt for Ribbons: At the end of every life, you are awarded a ribbon based on how you lived (e.g., "Hero," "Scandalous," "Lazy," or "Rich"). Trying to collect all the different ribbons is a great way to give yourself specific goals. Don't be afraid of the absurd: The real charm of the game is in its wild unpredictability. Sometimes, making terrible choices, trying to become a famous actor, or buying a crazy exotic pet leads to the most memorable playthroughs. Don't always play it safe! Conclusion Ultimately, the beauty of this simulator lies in its endless replayability. Every time you hit the button to start a new life, it is a completely blank slate. You can be a saint in one lifetime and an absolute menace to society in the next. Whether you have five minutes to kill on a bus commute or an hour to craft a sprawling, multi-generational family dynasty, diving into Bitlife offers a fun, lighthearted escape into a world where you pull all the strings. Give it a try, and see exactly where your choices take you!

Why Saving Your Game Can Be One of the Most Stressful Moments in Horror

by explicit.gerbil.htxg＠hidingmail.net

Saving progress should feel comforting. You've survived a difficult section. You've made it through another encounter. Your progress is secure. In theory, a save point represents safety. Yet some of the most memorable horror games somehow make saving feel tense. I've always found that fascinating. In most genres, saving is a completely mechanical action. You barely think about it. Open a menu, press a button, move on. In horror games, however, save systems often become part of the experience itself. Sometimes they even become part of the fear. Safety Feels Temporary One thing horror games understand exceptionally well is that safety and danger become more meaningful when they exist side by side. A safe room feels comforting because the rest of the world doesn't. A save point feels valuable because progress can be lost. That contrast creates emotional weight. I still remember older survival horror games where reaching a save location felt like completing a journey. Not because the act of saving was exciting. Because getting there was. Every hallway between me and that room carried risk. Every enemy encounter threatened valuable resources. Every mistake felt expensive. The save point became more than a feature. It became a destination. Relief Can Be an Emotion Too People often discuss fear when talking about horror games. Relief deserves more attention. In many ways, relief is one of the most important emotions the genre creates. Without moments of relief, tension eventually becomes exhausting. Players need opportunities to recover. Save rooms often provide exactly that. The music changes. The atmosphere softens. The pressure decreases. For a few moments, players can breathe. Those quiet pauses create an interesting effect. Instead of weakening the horror, they strengthen it. The next dangerous section feels more intense because you've experienced a brief sense of comfort. The contrast matters. Fear isn't effective when it never changes. Limited Saving Changes Behavior Some horror games allow unlimited saves. Others place restrictions on them. Whether through limited resources, specific locations, or special conditions, these systems dramatically influence how players think. I've noticed that limited saving changes decision-making almost immediately. Players become cautious. Resources feel more valuable. Exploration becomes riskier. Every choice carries additional weight because mistakes have consequences. Suddenly, saving isn't just a technical feature. It's a strategic decision. Should I save now? Should I keep going? Can I survive the next section without doing it? These questions create tension even when no immediate threat exists. That's impressive design. The game generates anxiety through decision-making rather than direct danger. The Walk Back Is Sometimes Scarier One of my favorite horror gaming experiences involves leaving a save room. Entering feels great. Leaving feels terrible. The moment you step back into the unknown, the comfort disappears. The music fades. The safety vanishes. The uncertainty returns. What's interesting is that nothing may have changed. The environment is the same. The enemies are the same. The layout remains familiar. Yet emotionally, everything feels different. You know you're moving away from security. That awareness alone increases tension. I've experienced situations where opening the door to leave a save room felt more intimidating than entering a boss area. Not because I expected a specific threat. Because I was abandoning certainty. Modern Horror Uses Saving Differently Contemporary horror games often approach saving in a less restrictive way. Autosaves are common. Checkpoints are frequent. Players rarely lose significant amounts of progress. That shift has obvious advantages. It reduces frustration and makes games more accessible. At the same time, it changes the emotional role of saving. Older horror games often transformed save systems into part of the atmosphere. Modern games typically treat them as invisible support systems. Neither approach is inherently better. They're simply pursuing different goals. One emphasizes vulnerability. The other prioritizes convenience. Interestingly, both can still create effective horror when used thoughtfully. For another perspective on player vulnerability, see our [discussion about why limited resources increase tension]. Safe Rooms Become Emotional Anchors Some locations in horror games remain memorable long after the details of the story fade. Safe rooms are often among them. Players remember how those spaces felt. The familiar music. The calm atmosphere. The temporary sense of control. I've finished games years ago and forgotten specific enemy encounters, yet I can still picture certain save rooms clearly. That's remarkable when you think about it. These locations rarely contain action. Nothing dramatic happens there. Their importance comes entirely from emotion. They provide stability within unstable worlds. The player develops a relationship with them. Returning feels reassuring. Leaving feels uncomfortable. Few game mechanics achieve that kind of emotional significance. Fear Feels Bigger When Progress Matters A major reason save systems affect horror so strongly is simple. Consequences matter. If players feel that failure costs nothing, tension often decreases. When progress becomes valuable, fear gains additional weight. Suddenly every encounter feels important. Every decision matters. Every mistake carries consequences beyond the immediate moment. This doesn't mean horror games need harsh punishment systems. Excessive penalties can easily become frustrating. But a small amount of risk often makes emotional investment stronger. Players care more because they have something to lose. And caring is essential for fear. Without investment, horror struggles to have lasting impact. The Psychology of "Just One More Room" I've fallen into this trap countless times. You're standing near a save point. Logic says you should save and stop playing. Instead, you think: "I'll check one more room." Then another room. Then another hallway. Then another objective. Before long, you've wandered into a situation far more dangerous than expected. Horror games thrive on this kind of curiosity. Players constantly balance caution against exploration. The save point represents security. The unexplored area represents possibility. Most of the time, curiosity wins. That's why horror games remain so engaging despite the fear they create. Players aren't simply avoiding danger. They're actively seeking answers. Why Save Points Remain Memorable Not every horror game uses traditional save rooms anymore. Not every game limits progress in meaningful ways. Yet the underlying idea remains powerful. Players need moments of safety. Moments of relief. Moments where tension briefly relaxes before building again. Save points became iconic because they delivered those emotions consistently. They represented hope within hostile environments. A reminder that survival was possible. A chance to regroup before facing whatever came next. And perhaps that's why so many horror fans remember them so fondly. They weren't frightening on their own. They mattered because of everything waiting outside. After all, what makes a safe place feel truly safe if there was never any danger to escape from in the first place? https://horrorgamesfree.com

Mental Health Tips Every College Student Should Follow

College life is often seen as an exciting phase filled with new experiences, independence, friendships, and opportunities. However, behind the social events and academic growth, many students also face stress, anxiety, loneliness, and pressure to perform well. Managing mental health during this time is just as important as achieving good grades, because emotional well-being directly impacts concentration, productivity, and overall success. Learning how to take care of your mental health can help students handle challenges more effectively and enjoy a more balanced college experience. Many students struggle to keep up with assignments, deadlines, and academic expectations, which can sometimes feel overwhelming. In such situations, academic support services like pay for someone to <a href="https://myassignmenthelp.com/ca/do-my-homework.html">do my homework online</a> from MyAssignmentHelp can help reduce academic pressure and allow students to focus on maintaining better mental and emotional well-being alongside their studies. Understanding Mental Health in College Life Mental health refers to a person’s emotional, psychological, and social well-being. In college, students go through major life transitions—moving away from home, adapting to new environments, managing finances, and handling academic responsibilities. All of these changes can affect mental stability. It is normal to feel stressed occasionally, but prolonged stress or emotional exhaustion should not be ignored. Recognizing early signs such as fatigue, loss of motivation, irritability, or difficulty concentrating is important for taking timely action. Maintain a Balanced Routine One of the most effective ways to support mental health is by maintaining a balanced daily routine. A structured lifestyle helps reduce chaos and creates a sense of stability. Students should try to: Follow a consistent sleep schedule Allocate time for study and relaxation Avoid last-minute cramming Include breaks between study sessions Set realistic daily goals A balanced routine helps prevent burnout and ensures that students do not feel overwhelmed by academic pressure. Prioritize Sleep and Rest Sleep plays a crucial role in mental health. Lack of sleep can increase stress levels, reduce concentration, and negatively impact memory. College students often sacrifice sleep to complete assignments or prepare for exams, but this habit can be harmful in the long run. Ideally, students should aim for 7–9 hours of quality sleep each night. Creating a bedtime routine, limiting screen time before sleep, and avoiding caffeine late in the day can significantly improve sleep quality. Stay Physically Active Physical activity is not just good for the body but also essential for mental well-being. Exercise releases endorphins, which are natural mood boosters. Students do not need intense workouts to benefit from physical activity. Simple habits like walking, cycling, yoga, or light stretching can make a big difference. Regular exercise helps: Reduce stress and anxiety Improve focus and concentration Boost energy levels Enhance overall mood Even 20–30 minutes of activity a day can have noticeable positive effects. Build Strong Social Connections Social support is one of the most important factors in maintaining good mental health. College is a great place to build friendships and connections that provide emotional support. Students should try to: Spend time with supportive friends Participate in group activities Join clubs or student organizations Talk openly about feelings when needed Having people to talk to can reduce feelings of loneliness and help students cope better with stress. Learn Stress Management Techniques Stress is unavoidable in college, but it can be managed effectively with the right techniques. Some helpful stress management strategies include: Deep breathing exercises Meditation and mindfulness practices Journaling thoughts and emotions Listening to calming music Taking short breaks during study sessions These techniques help calm the mind and improve emotional balance. Avoid Overloading Yourself Many students try to take on too many responsibilities at once—academics, part-time jobs, extracurricular activities, and social commitments. While involvement is important, overloading can lead to burnout. Learning to say no when necessary is a healthy habit. Students should prioritize tasks based on importance and avoid unnecessary pressure. It is better to do a few things well than to do everything poorly due to exhaustion. Seek Help When Needed One of the most important aspects of mental health is recognizing when help is needed. Unfortunately, many students hesitate to seek support due to stigma or fear of judgment. However, asking for help is a sign of strength, not weakness. Support can come from: Friends and family College counselors Mentors or professors Mental health professionals Talking about problems can provide relief and open up solutions that may not be visible when dealing with stress alone. Limit Social Media Usage While social media helps students stay connected, excessive use can negatively affect mental health. Constant comparison with others, exposure to unrealistic lifestyles, and online pressure can increase anxiety and reduce self-esteem. Students should: Set time limits for social media use Avoid comparing themselves to others Take digital detox breaks Focus on real-life interactions Reducing screen time can improve focus, productivity, and emotional well-being. Practice Self-Care Regularly Self-care is essential for maintaining mental balance. It involves taking time to do activities that bring relaxation and happiness. Self-care can include: Reading a book Watching a favorite show Spending time in nature Pursuing hobbies Taking rest without guilt Prioritizing self-care helps recharge the mind and improves resilience against stress. Develop a Positive Mindset A positive mindset plays a major role in mental health. College life comes with challenges, and setbacks are a normal part of the journey. Instead of focusing on failures, students should: Learn from mistakes Celebrate small achievements Stay hopeful during difficult times Practice gratitude Positive thinking helps build confidence and reduces emotional distress. Maintain Academic Balance Academic pressure is one of the biggest sources of stress for college students. Managing coursework effectively can significantly improve mental health. Students should break tasks into smaller steps, avoid procrastination, and seek academic support when necessary. Staying organized can reduce last-minute stress and improve overall performance. Conclusion Mental health is a vital part of a successful and fulfilling college experience. Students who take care of their emotional well-being are more likely to perform better academically, build stronger relationships, and enjoy their college journey. By maintaining a balanced routine, staying physically active, managing stress, and seeking support when needed, students can create a healthier and more positive lifestyle. Remember, college is not just about academic achievement—it is also about growing as a person, and mental well-being
