From 42328003ecb6a5446a6f33424891e391f0a16575 Mon Sep 17 00:00:00 2001 From: "Wachowski, Karol" Date: Wed, 14 Feb 2024 09:13:04 +0100 Subject: accel/ivpu: Refactor BO creation functions Rename BO allocate/create functions, so the code is more consistent. There are now two matching buffer creation functions: - ivpu_bo_create_ioctl() - create a BO from user space - ivpu_bo_create() - create a BO from kernel space ivpu_bo_alloc() is now only used to allocate struct ivpu_bo which better matches its name.
