This commit modifies the construct_phy function to handle the case where `bios->integrated_info` is NULL and to address a compiler warning about a large stack allocation. Upon examination, it was found that the local `integrated_info` structure was just used to copy values which is large and was being declared directly on the stack which could potentially lead to performance issues. This commit changes the code to use `bios->integrated_info` directly, which avoids the need for a large stack allocation. The function now checks if `bios->integrated_info` is NULL before entering a for loop that uses it. If `bios->integrated_info` is NULL, the function skips the for loop and continues executing the rest of the code. This ensures that the function behaves correctly when `bios->integrated_info` is NULL and improves compatibility with dGPUs. Fixes the below with gcc W=1: drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c: In function ‘construct_phy’: drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_factory.c:743:1: warning: the frame size of 1056 bytes is larger than 1024 bytes [-Wframe-larger-than=] Cc: Wenjing Liu <wenjing.liu@amd.com> Cc: Jerry Zuo <jerry.zuo@amd.com> Cc: Qingqing Zhuo <qingqing.zhuo@amd.com> Cc: Tom Chung <chiahsuan.chung@amd.com> Cc: Alvin Lee <alvin.lee2@amd.com> Cc: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Cc: Roman Li <roman.li@amd.com> Cc: Hersen Wu <hersenxs.wu@amd.com> Cc: Alex Hung <alex.hung@amd.com> Cc: Aurabindo Pillai <aurabindo.pillai@amd.com> Cc: Harry Wentland <harry.wentland@amd.com> Signed-off-by:

This commit fixes a format truncation issue arosed by the snprintf function potentially writing more characters into the ring->name buffer than it can hold, in the amdgpu_gfx_kiq_init_ring function The issue occurred because the '%d' format specifier could write between 1 and 10 bytes into a region of size between 0 and 8, depending on the values of xcc_id, ring->me, ring->pipe, and ring->queue. The snprintf function could output between 12 and 41 bytes into a destination of size 16, leading to potential truncation. To resolve this, the snprintf line was modified to use the '%hhu' format specifier for xcc_id, ring->me, ring->pipe, and ring->queue. The '%hhu' specifier is used for unsigned char variables and ensures that these values are printed as unsigned decimal integers. Fixes the below with gcc W=1: drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c: In function ‘amdgpu_gfx_kiq_init_ring’: drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:332:61: warning: ‘%d’ directive output may be truncated writing between 1 and 10 bytes into a region of size between 0 and 8 [-Wformat-truncation=] 332 | snprintf(ring->name, sizeof(ring->name), "kiq_%d.%d.%d.%d", | ^~ drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:332:50: note: directive argument in the range [0, 2147483647] 332 | snprintf(ring->name, sizeof(ring->name), "kiq_%d.%d.%d.%d", | ^~~~~~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/amdgpu_gfx.c:332:9: note: ‘snprintf’ output between 12 and 41 bytes into a destination of size 16 332 | snprintf(ring->name, sizeof(ring->name), "kiq_%d.%d.%d.%d", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 333 | xcc_id, ring->me, ring->pipe, ring->queue); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fixes: 345a36c4 ("drm/amdgpu: prefer snprintf over sprintf") Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Signed-off-by: -
