xe_vma_has_d...lt_mem_attrs(9)

🌸 NAME 🌸

xe_vma_has_default_mem_attrs — check if a VMA has default memory attributes 💖

✨ SYNOPSIS ✨

bool xe_vma_has_default_mem_attrs (struct xe_vma *vma );

🎀 ARGUMENTS 🎀

• vma — pointer to the xe_vma structure to check 🫶

🦋 DESCRIPTION 🦋

okay bestie, this function is doing a little vibe check on the given VMA (Virtual Memory Area): does it have its memory attributes set to their default values? Specifically, it checks all of these conditions:

• atomic_access is DRM_XE_VMA_ATOMIC_UNDEFINED
• pat_index is equal to default_pat_index
• preferred_loc.devmem_fd is DRM_XE_PREFERRED_LOC_DEFAULT_DEVICE
• preferred_loc.migration_policy is DRM_XE_MIGRATE_ALL_PAGES

👑 RETURN 👑

true if all attributes are at their default values, false otherwise. no cap 💅
