[PATCH 1/2] lib/amdgpu: refactor deadlock tests
vitaly.prosyak at amd.com
vitaly.prosyak at amd.com
Thu Jul 25 22:05:07 UTC 2024
From: Vitaly Prosyak <vitaly.prosyak at amd.com>
Refactor error handling and simplify code for packet processing
- Declare different error types for packets in a central location for
better manageability and consistency.
- Implement ASIC-specific function bad_write_linear to handle specific
hardware requirements.
- Simplify the function bad_access_helper to streamline error handling
and improve code readability.
These changes enhance the maintainability of the code and ensure that
error handling is more robust and easier to update.
