[-- Attachment #1 --] Engineer a Feature Complete Port of Intel's igt-gpu-tools for FreeBSD A quick introduction: Intel’s igt-gpu-tools serves as a generic testing suite for drm drivers on Linux. The igt-gpu-tools suite is separated into tests and tools that target kms, memory management, and command submission. This low-level reporting allows for transparent tracking of kernel changes and efficient debugging of modern drm drivers. Progress: Over the last week I've nearly gotten igt-gpu-tools to compile by including C preprocessor macros that check if __linux__ is defined. Since I am compiling on FreeBSD, __linux__ has no value and therefore the nested code is disregarded. This approach is certainly not perfect, but it is also temporary. I am ~95% of the way through compilation with a few difficult errors to sort out. Once the program compiles successfully, I plan on rewriting POSIX compliant versions of the Linux-specific code that I ignored with the __linux__ macro. I will prioritize certain features and start the rewriting process. Some notable FreeBSD absentees are debugfs, libkmod, libprocps, Linux performance events, and Linux userfaultfd. Once the FreeBSD compatible code is complete, I plan to test the modified igt tests using a host of graphics processors on FreeBSD 14.0-CURRENT.
