drm/amdgpu: Replace one-elements array with flex-array members

2022-11-15T18:35:16+00:00

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in structs ATOM_I2C_VOLTAGE_OBJECT_V3, ATOM_ASIC_INTERNAL_SS_INFO_V2, ATOM_ASIC_INTERNAL_SS_INFO_V3, and refactor the rest of the code accordingly. Important to mention is that doing a build before/after this patch results in no functional binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].

drm/amd/display: fix array index out of bound error in bios parser

2022-11-15T18:35:14+00:00

[Why&How] Firmware headers dictate that gpio_pin array only has a size of 8. The count returned from vbios however is greater than 8. Fix this by not using array indexing but incrementing the pointer since gpio_pin definition in atomfirmware.h is hardcoded to size 8 Reviewed-by: Martin Leung Acked-by: Tom Chung Signed-off-by: Aurabindo Pillai Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher

drm/amd/display: Support parsing VRAM info v3.0 from VBIOS

2022-11-15T16:53:35+00:00

[Why] For DCN3.2 and DCN3.21, VBIOS has switch to using v3.0 of the VRAM info struct. We should read and override the VRAM info in driver with values provided by VBIOS to support memory downbin cases.

drm/amdgpu: Replace one-element array with flex-array member

2022-11-10T20:30:02+00:00

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element array with flexible-array member in structs _ATOM_CONNECTOR_DEVICE_TAG_RECORD, _ATOM_OBJECT_GPIO_CNTL_RECORD, _ATOM_BRACKET_LAYOUT_RECORD, _ATOM_BRACKET_LAYOUT_RECORD, _ATOM_LEAKAGE_VOLTAGE_OBJECT_V3, _ATOM_FUSION_SYSTEM_INFO_V3, _ATOM_I2C_DATA_RECORD, _ATOM_I2C_DEVICE_SETUP_INFO, _ATOM_ASIC_MVDD_INFO and refactor the rest of the code accordingly. While at it, removed a redundant casting. Important to mention is that doing a build before/after this patch results in no binary output differences. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [1].
