[**\[Experimental Bot, please feedback here\]**](https://github.com/search?q=repo%3Aapache%2Fnuttx+13552&type=issues) No, this PR summary does not adequately meet the NuttX requirements. Here's why and how to fix it: **Missing Information in Summary:** * **Why is the change necessary?** The summary mentions a common use case, but doesn't explain *why* it should be default enabled. Is it frequently requested? Does it solve a specific problem? Justify the change beyond just its utility. For example: "Enabling `/dev/zero` by default simplifies performance testing and reduces configuration overhead for users, as it's a commonly used device." * **What functional part of the code is being changed?** Vague reference to "Nuttx's built-in boards' defconfig". Be specific. Which files are modified? Is this a Kconfig change? Which subsystem is affected (Device drivers, core OS, etc.)? For example: "This change modifies the default configuration in the Kconfig files for various boards to enable the `/dev/zero` device driver when `DEFAULT_SMALL` is not enabled." * **How does the change exactly work?** While it states *what* will change (default enable), it doesn't describe *how*. Does it involve a Kconfig option modification? Is any code added or removed? For example: "The `CONFIG_DEV_ZERO` option is set to 'y' in the relevant defconfig files when `CONFIG_DEFAULT_SMALL` is not selected." **Missing Information in Impact:** * All impact sections are answered too briefly or with placeholders. Be explicit. * **Is new feature added? Is existing feature changed?** "Yes, existing feature changed. The `/dev/zero` device driver, which was previously disabled by default (unless `DEFAULT_SMALL` was used), is now enabled by default." * **Impact on user:** Even if the answer is NO, explain why. "No, users will not need to adapt. The `/dev/zero` device will be available without any explicit configuration, simplifying common use cases." If a user *might* have to adapt (e.g., size changes), document that! * **Impact on build:** "Potentially YES. The resulting kernel image might be slightly larger due to the inclusion of the `/dev/zero` driver. This impact is expected to be minimal." * **Impact on hardware:** "NO. This change affects only the kernel configuration and does not introduce any new hardware dependencies." * **Impact on documentation:** If NO, confirm: "NO, documentation updates are not required as this is a default configuration change." If YES, describe what documentation is changed. * **Impact on security:** "NO, this change has no security implications. The `/dev/zero` device has a well-defined and limited functionality." * **Impact on compatibility:** "NO, this change does not affect backward or forward compatibility." **Missing Information in Testing:** * **Build Host(s):** Provide details: "Linux (Ubuntu 20.04), x86_64, GCC 9.4.0" * **Target(s):** Be specific! "qemu-x86_64:nsh_net", "sim:nsh", "stm32f4discovery:nsh" List *all* tested targets. * **Testing logs:** Absolutely essential. Show commands used and relevant output before and after the change to demonstrate that the `/dev/zero` device is now available and functions correctly. Example: ``` Before: $ ls /dev | grep zero # No output After: $ ls /dev | grep zero zero $ dd if=/dev/zero of=/tmp/test bs=1k count=10 10+0 records in 10+0 records out 10240 bytes (10 kB) copied, 0.000180119 s, 56.8 MB/s ``` By providing this level of detail, reviewers can properly assess the PR and ensure it meets the project's standards. Conciseness is good, but not at the expense of clarity and completeness. -- This is an automated message from the Apache Git Service.
