+# GitHub Copilot Instructions for AcreetionOS Kernel Development
+
+This file provides guidelines for GitHub Copilot when assisting with code generation and modification in the AcreetionOS Linux kernel project.
+
+## Copyright and Licensing
+
+**ALWAYS** include the following header in every new file created:
+
+```c
+/* SPDX-License-Identifier: GPL-2.0 */
+/*
+ * [Brief file description]
+ * Copyright (c) ArttulOS Project
+ *
+ * [Additional file description if needed]
+ */
+```
+
+For C source files (.c):

+/*

+ */
+```
+
+## Coding Standards
+
+### Language and Style
+- **Strict C11/C89 compliance**: Use kernel-style C (GNU89)
+- **No C++ features**: This is pure C code
+- **No floating-point operations** in kernel space
+- Follow Linux kernel coding style (as documented in the kernel's Documentation/process/coding-style.rst)
+
+### Memory Safety - HIGHEST PRIORITY
+1. **Always check return values** from memory allocation functions
+2. **Use bounds checking** for all array accesses
+3. **Initialize all variables** before use
+4. **Validate all pointers** before dereferencing
+5. **Check buffer sizes** before copying data
+6. **Use safe string functions**: Prefer `strscpy()` over `strcpy()`, `snprintf()` over `sprintf()`
+
+### Defensive Programming Patterns
+
+#### Memory Allocation
+```c
+/* GOOD - Always check allocation results */
+ptr = kmalloc(size, GFP_KERNEL);
+if (!ptr) {
+    pr_err("Failed to allocate memory\n");
+    return -ENOMEM;
+}
+
+/* Initialize allocated memory */
+memset(ptr, 0, size);
+```
+
+#### Pointer Validation
+```c
+/* GOOD - Always validate pointers */
+if (!ptr) {
+    pr_err("Invalid pointer\n");
+    return -EINVAL;
+}
+```
+
+#### Array Bounds
+```c
+/* GOOD - Check bounds before access */
+if (index >= array_size) {
+    pr_err("Index out of bounds\n");
+    return -EINVAL;
+}
+value = array[index];
+```
+
+#### String Operations
+```c
+/* GOOD - Use safe string functions */
+strscpy(dest, src, sizeof(dest));
+
+/* GOOD - Always null-terminate */
+dest[sizeof(dest) - 1] = '\0';
+```
+
+#### Resource Cleanup
+```c
+/* GOOD - Always clean up resources */
+ptr = kmalloc(size, GFP_KERNEL);
+if (!ptr)
+    return -ENOMEM;
+
+/* ... use ptr ... */
+
+/* Cleanup */
+kfree(ptr);
+ptr = NULL;  /* Prevent use-after-free */
+```
+
+### Error Handling
+- **Return appropriate error codes**: Use standard Linux error codes (e.g., -ENOMEM, -EINVAL, -EIO)
+- **Log errors appropriately**: Use pr_err(), pr_warn(), pr_info(), pr_debug()
+- **Clean up on error paths**: Free allocated resources before returning errors
+- **Use goto for cleanup**: Centralize cleanup code in error handling
+
+```c
+/* GOOD - Centralized cleanup */
+int function(void)
+{
+    struct resource *res = NULL;
+    int ret = 0;
+
+    res = allocate_resource();
+    if (!res) {
+        ret = -ENOMEM;
+        goto err_alloc;
+    }
+
+    ret = perform_operation(res);
+    if (ret)
+        goto err_operation;
+
+    return 0;
+
+err_operation:
+    free_resource(res);
+err_alloc:
+    return ret;
+}
+```
+
+### Integer Operations
+- **Check for overflow**: Use `check_add_overflow()`, `check_mul_overflow()`, etc.
+- **Use appropriate types**: Match variable types to their usage
+- **Be careful with signed/unsigned**: Avoid mixing signed and unsigned in comparisons
+
+### Concurrency and Locking
+- **Document locking requirements**: Comment which locks protect which data
+- **Hold locks for minimal time**: Don't perform blocking operations while holding spinlocks
+- **Use appropriate lock types**: Spinlocks for short critical sections, mutexes for longer ones
+- **Prevent deadlocks**: Acquire locks in consistent order
+
+### Comments and Documentation
+- **Document complex algorithms**: Explain *why*, not just *what*
+- **Use kernel-doc format** for function documentation
+- **Keep comments up-to-date**: Update comments when changing code
+- **Document assumptions**: State preconditions and postconditions
+
+```c
+/**
+ * function_name - Brief description
+ * @param1: Description of parameter 1
+ * @param2: Description of parameter 2
+ *
+ * Detailed description of what the function does.
+ *
+ * Return: Description of return value
+ */
+```
+
+### Project-Specific Guidelines
+
+#### High Availability Focus
+- **Fail gracefully**: Handle errors without crashing
+- **Validate all inputs**: Never trust user-space or hardware data
+- **Use defensive assertions**: Check invariants with BUG_ON/WARN_ON appropriately
+- **Implement proper error recovery**: Try to recover from errors when possible
+
+#### Accessibility Considerations
+- **Clear error messages**: Make diagnostic output understandable
+- **Avoid obscure abbreviations**: Use clear, descriptive names
+- **Consistent interfaces**: Follow established patterns in the codebase
+
+#### Hardware Enablement (HWE)
+- **Support modern hardware**: Prioritize current hardware standards
+- **Maintain backward compatibility**: Don't break support for older hardware unnecessarily
+- **Document hardware quirks**: Note any hardware-specific workarounds
+
+## Prohibited Practices
+
+1. **Never use floating-point** operations (including SSE/AVX instructions in kernel space)
+2. **Never ignore return values** from functions that can fail
+3. **Never use unsafe functions**: strcpy, strcat, sprintf, gets
+4. **Never assume memory is zero-initialized** unless explicitly cleared
+5. **Never dereference NULL pointers**
+6. **Never introduce race conditions**: Always protect shared data
+7. **Never leak resources**: Always free allocated memory/handles
+8. **Never use magic numbers**: Define constants with meaningful names
+
+## Build and Test Requirements
+
+- **Code must compile without warnings** with `-Wall -Werror`
+- **Static analysis must pass**: No sparse warnings
+- **Code must pass checkpatch.pl**: Follow kernel style guidelines
+- **All changes must include appropriate tests** when applicable
+
+## Security
+
+- **Input validation is mandatory**: Validate all data from user space or hardware
+- **No buffer overflows**: Check all buffer operations
+- **No integer overflows**: Validate arithmetic operations
+- **Proper privilege checking**: Verify permissions before operations
+- **Sanitize output**: Prevent information leaks
+
+## Priority Order for Code Quality
+
+1. **Security**: No vulnerabilities
+2. **Memory safety**: No memory corruption
+3. **Correctness**: Code does what it should
+4. **Stability**: Handles errors gracefully
+5. **Performance**: Efficient implementation
+6. **Readability**: Clear and maintainable
+
+---
+
+*These guidelines ensure the AcreetionOS kernel maintains the highest standards for stability, security, and accessibility.*

-Hardware Enablement Kernel for archlinux
+# AcreetionOS Linux Kernel
+
+This is the core kernel for **AcreetionOS**, developed under the **ArttulOS Project** umbrella.
+
+## Project Overview
+
+AcreetionOS is a Linux-based operating system focused on:
+- **Chronic-pain-accessible OS development**: Designed with accessibility and user comfort as primary concerns
+- **High availability**: Optimized for 99.9% uptime and exceptional stability
+- **Modern hardware support**: Based on Hardware Enablement (HWE) philosophy to ensure compatibility with contemporary hardware
+
+## Architecture
+
+This kernel follows the standard Linux kernel layout with the following core directories:
+- `/arch` - Architecture-specific code
+- `/drivers` - Device drivers
+- `/fs` - Filesystems
+- `/include` - Header files
+- `/init` - Initialization code
+- `/ipc` - Inter-process communication
+- `/kernel` - Core kernel code
+- `/mm` - Memory management
+- `/net` - Networking stack
+- `/scripts` - Build and maintenance scripts
+
+## Credits
+
+**AcreetionOS** is developed and maintained by the **ArttulOS Project**.
+
+Copyright (c) ArttulOS Project
+
+## License
+
+This project is licensed under the GNU General Public License v2.0 (GPL-2.0). See the LICENSE file for details.
+
+## Building
+
+Build instructions will be added as the kernel development progresses.
+
+## Contributing
+
+Contributions are welcome! Please ensure all code follows:
+- Strict C11/C89 kernel-style coding standards
+- No floating point operations in kernel space
+- GPL-2.0 headers on all files
+- Memory safety and defensive programming practices

Subject: [PATCH 4/5] Fix code review issues: remove *.gcno duplicate, fix ARCH
 value, improve secret check

- Remove duplicate *.gcno entry from .gitignore
- Fix CI workflow to use ARCH=x86 instead of x86_64 (matches Makefile)
- Improve hardcoded secret check to fail explicitly when secrets found
