xe_guc_buf_from_data(9)

🎀 NAME 🎀

okay so this is the xe_guc_buf_from_data(9) page from the Kernel API Manual — and the whole vibe is: xe_guc_buf_from_data — Reserve a new sub-allocation using data. 💖

🌸 SYNOPSIS 🌸

like, the signature is literally:

struct xe_guc_buf xe_guc_buf_from_data (struct xe_guc_buf_cache *cache ,
       const void *data , size_t size );

🫶 ARGUMENTS 🫶

• cache — the xe_guc_buf_cache where reserve sub-allocation 🫶
• data — the data to flush the sub-allocation 💾
• size — the size of the data 📏

💅 DESCRIPTION 💅

So it’s similar to xe_guc_buf_reserve but it flushes data to the GPU memory ✨. That’s the tea.

🎁 RETURN 🎁

Returns a xe_guc_buf of new sub-allocation 💖.
