[PATCH v2 2/2] drm/uapi: add explicit virtgpu context debug name

2023-10-18 Thread Gurchetan Singh

There are two problems with the current method of determining the virtio-gpu debug name. 1) TASK_COMM_LEN is defined to be 16 bytes only, and this is a Linux kernel idiom (see PR_SET_NAME + PR_GET_NAME). Though, Android/FreeBSD get around this via setprogname(..)/getprogname(..) in libc.
