Look no further than Monkey Mart, a charming and surprisingly addictive management game that’s perfect for a quick pick-me-up or a lengthy play session. This delightful title offers a unique blend of farming, crafting, and entrepreneurial spirit, all wrapped up in an adorable pixel art package. Let’s dive into what makes Monkey Mart such a joy to experience. Welcome to the Jungle Aisle: Introduction to Monkey Mart https://monkeymartfree.com Monkey Mart isn't just another clicker game; it's a vibrant ecosystem where monkeys are the farmers, the craftspeople, and the cashiers. Your goal is simple: grow a variety of crops, process them into sellable goods, and keep your customers happy, all while expanding your monkey empire. The game is incredibly accessible, making it suitable for players of all ages and experience levels. Whether you're a seasoned gamer or just looking for a relaxing way to unwind, Monkey Mart offers a rewarding and engaging experience. You can easily find yourself immersed in this charming world by visiting the official game at Monkey Mart. A Day in the Life of a Monkey Mogul: Understanding the Gameplay The core gameplay loop of Monkey Mart is deceptively simple yet endlessly engaging. You start with a small plot of land and a single monkey. Plant bananas, harvest them, and then have your monkey stock the shelves. As you earn money from sales, you can unlock new crops like corn and coffee, and more importantly, new processing stations. This is where the magic happens! Bananas can be turned into banana smoothies, coffee beans into steaming cups of joe, and corn into popcorn. Each new product opens up new revenue streams and demands a more intricate production line. Soon, you'll be hiring more monkeys, each specializing in a different task: planting, harvesting, processing, or cashiering. The game encourages strategic placement of your monkeys and stations to optimize efficiency. Watch as your little primate team scurries around, diligently working to keep your mart thriving.

Diversify your crops to offer a wider range of products and appeal to more customers. Thirdly, optimize your layout. Group similar stations together and ensure your monkeys have clear paths to minimize travel time. Experiment with different arrangements to find what works best for your growing mart. Finally, don't forget your cashiers! A long line of waiting customers means lost revenue, so ensure you have enough monkeys at the checkout. Conclusion: More Than Just a Game, It's a Monkey Metropolis! Monkey Mart is more than just a time-killer; it’s a delightful simulation that rewards planning, efficiency, and a touch of entrepreneurial spirit. Its charming visuals, intuitive controls, and satisfying progression system make it a truly enjoyable experience. Whether you're looking to unwind with a casual game or delve into a deeper management challenge, Monkey Mart offers a refreshing and endearing journey into the world of primate-powered retail. So, put on your managerial hat, gather your monkey crew, and get ready to build the most successful monkey mart the jungle has ever seen!

[PATCH] drm/amdkfd: Fix an error handling path in amdgpu_amdkfd_get_dmabuf_info()

[PATCH 0/5] Replace the dmabuf custom test framework with kunit

by Jason Gunthorpe

Using kunit to write tests for new work on dmabuf is coming up: https://lore.kernel.org/all/26-v1-b5cab63049c0+191af-dmabuf_map_type_jgg@nv… Replace the custom test framework with kunit to avoid maintaining two concurrent test frameworks. The conversion minimizes code changes and uses simple pattern-oriented reworks to reduce the chance of breaking any tests. Aside from adding the kunit_test_suite() boilerplate, the conversion follows a number of patterns: Test failures without cleanup. For example: if (!ptr) return -ENOMEM; Becomes: KUNIT_ASSERT_NOT_NULL(test, ptr); In kunit ASSERT longjumps out of the test. Check for error, fail and cleanup: if (err) { pr_err("msg\n"); goto cleanup; } Becomes: if (err) { KUNIT_FAIL(test, "msg"); goto cleanup; } Preserve the existing failure messages and cleanup code. Cases where the test returns err but prints no message: if (err) goto cleanup; Becomes: if (err) { KUNIT_FAIL(test, "msg"); goto cleanup; } Use KUNIT_FAIL to retain the 'cleanup on err' behavior. Overall, the conversion is straightforward. The result can be run with kunit.py: $ tools/testing/kunit/kunit.py run --build_dir build_kunit_x86_64 --arch x86_64 --kunitconfig ./drivers/dma-buf/.kunitconfig [20:37:23] Configuring KUnit Kernel ...

All other usual ways to run kunit work as well, and all tests are placed in a module to provide more options for how they are run. AI was used to do the large scale semantic search and replaces described above, then everything was hand checked. AI also deduced the issue with test_race_signal_callback() in a couple of seconds from the kunit crash (!!), again was hand checked though I am not so familiar with this test to be fully certain this is the best answer.

[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.

[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.
