hl_unreserve_va_block(9)

🌸 NAME

okay so bestie, hl_unreserve_va_block is literally a wrapper for add_va_block to unreserve a va block. That’s the whole NAME moment, no cap. And yes, this is the hl_unreserve_va_block(9) page from the Kernel API Manual — folding the manual name in right here so we don’t have to copy the header line, periodt. 🫶

✨ SYNOPSIS

int hl_unreserve_va_block (struct hl_device *hdev , struct hl_ctx *ctx ,
u64 start_addr , u64 size );

🎀 ARGUMENTS

• hdev — pointer to the habanalabs device structure
• ctx — pointer to the context structure.
• start_addr — start virtual address.
• size — number of bytes to unreserve.

🦋 DESCRIPTION

This function does the following:

• Takes the list lock and calls add_va_block_locked.

That’s the whole plot, fr fr. 💅
