From b5a52d2afe1b75f9d51461bb235ca40735e99fe7 Mon Sep 17 00:00:00 2001 From: Sam James Date: Sun, 5 Nov 2023 16:06:50 +0000 Subject: amdgpu: Adjust kmalloc_array calls for new -Walloc-size MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GCC 14 introduces a new -Walloc-size included in -Wextra which errors out on various files in drivers/gpu/drm/amd/amdgpu like: ``` amdgpu_amdkfd_gfx_v8.c:241:15: error: allocation of insufficient size ‘4’ for type ‘uint32_t[2]’ {aka ‘unsigned int[2]'} with size ‘8’ [-Werror=alloc-size] ``` This is because each HQD_N_REGS is actually a uint32_t[2]. Move the * 2 to the size argument so GCC sees we're allocating enough. Originally did 'sizeof(uint32_t) * 2' for the size but a friend suggested 'sizeof(**dump)' better communicates the intent.
