hl_mem_area_crosses_range(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… hl_mem_area_crosses_range(9) β€” Kernel API Manual

okay so bestie, welcome to hl_mem_area_crosses_range, straight out of the Kernel API Manual ✨ this one's a lil bool-returning cutie that answers the eternal question: does this memory area cross into a range? πŸŽ€


✨ SYNOPSIS ✨

bool hl_mem_area_crosses_range (u64 address , u32 size , u64
range_start_address , u64 range_end_address );

like, four args, one bool out. it's giving "simple but important" energy fr fr πŸ’…


🌸 ARGUMENTS 🌸

  • address β€” the start address of the area we wanna validate. the beginning of the story, the main character's origin 🫢
  • size β€” the size in bytes of the area we're validating. how much of the story there is, bestie πŸ“
  • range_start_address β€” the start address of the valid range. where the valid zone begins, no cap ✨
  • range_end_address β€” the end address of the valid range. and where it stops, periodt πŸ›‘

πŸ‘‘ RETURN πŸ‘‘

  • true β€” the area overlaps part or all of the valid range 😭 yes even a little bit counts, overlap is overlap
  • false β€” otherwise. no overlap, no drama, we move πŸ’€

πŸ¦‹ SEE ALSO πŸ¦‹

okay bestie, buckle up, this is the long part πŸ’– the whole thing lives in the kernel file ./drivers/accel/habanalabs/common/habanalabs.h, and it's friends with literally everyone:
