drm/amd/pm: Replace one-element array with flexible-array in struct _ATOM_Vega10_GFXCLK_Dependency_Table There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Use flexible-array member in struct _ATOM_Vega10_GFXCLK_Dependency_Table, instead of one-element array. Also, this helps with the ongoing efforts to enable -Warray-bounds and fix the following warning: drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/vega10_hwmgr.c: In function ‘vega10_get_pp_table_entry_callback_func’: drivers/gpu/drm/amd/amdgpu/../pm/powerplay/hwmgr/vega10_hwmgr.c:3113:30: warning: array subscript 4 is above array bounds of ‘ATOM_Vega10_GFXCLK_Dependency_Record[1]’ {aka ‘struct _ATOM_Vega10_GFXCLK_Dependency_Record[1]’} [-Warray-bounds] 3113 | gfxclk_dep_table->entries[4].ulClk; | ~~~~~~~~~~~~~~~~~~~~~~~~~^~~ [1] https://en.wikipedia.org/wiki/Flexible_array_member [2] https://www.kernel.org/doc/html/v5.9/process/deprecated.html#zero-length-and-one-element-arrays Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/109Build-tested-by:kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/lkml/6023ff3d.WY3sSCkGRQPdPlVo%25lkp@intel.com/Signed-off-by:

There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct SISLANDS_SMC_SWSTATE, instead of a one-element array, and use the struct_size() helper to calculate the size for the allocation. Also, this helps with the ongoing efforts to enable -Warray-bounds and fix the following warnings: drivers/gpu/drm/amd/amdgpu/../pm/powerplay/si_dpm.c:2448:20: warning: array subscript 1 is above array bounds of ‘SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’ {aka ‘struct SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’} [-Warray-bounds] drivers/gpu/drm/amd/amdgpu/../pm/powerplay/si_dpm.c:2449:20: warning: array subscript 1 is above array bounds of ‘SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’ {aka ‘struct SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’} [-Warray-bounds] drivers/gpu/drm/amd/amdgpu/../pm/powerplay/si_dpm.c:2450:20: warning: array subscript 1 is above array bounds of ‘SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’ {aka ‘struct SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’} [-Warray-bounds] drivers/gpu/drm/amd/amdgpu/../pm/powerplay/si_dpm.c:2451:20: warning: array subscript 1 is above array bounds of ‘SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’ {aka ‘struct SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’} [-Warray-bounds] drivers/gpu/drm/amd/amdgpu/../pm/powerplay/si_dpm.c:2452:20: warning: array subscript 1 is above array bounds of ‘SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’ {aka ‘struct SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’} [-Warray-bounds] drivers/gpu/drm/amd/amdgpu/../pm/powerplay/si_dpm.c:5570:20: warning: array subscript 1 is above array bounds of ‘SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’ {aka ‘struct SISLANDS_SMC_HW_PERFORMANCE_LEVEL[1]’} [-Warray-bounds] [1] https://en.wikipedia.org/wiki/Flexible_array_member [2] https://www.kernel.org/doc/html/v5.9/process/deprecated.html#zero-length-and-one-element-arrays Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/109Build-tested-by: -

Use debugfs API directly instead of drm middle layer. This also includes following debugfs file output changes: 1 amdgpu_evict_vram/amdgpu_evict_gtt output will not contain any braces. e.g. (0) --> 0 2 amdgpu_gpu_recover output will print return value of amdgpu_device_gpu_recover() instead of not so important "gpu recover" message. v2: * checkpatch.pl: use '0444' instead of S_IRUGO. * remove S_IFREG from mode. * remove mode variable.

dcn21_validate_bandwidth() calls functions that use floating point math. On my machine this sometimes results in simd exceptions when there are other FPU users such as KVM virtual machines running. The screen freezes completely in this case. Wrapping the function with DC_FP_START()/DC_FP_END() seems to solve the problem. This mirrors the approach used for dcn20_validate_bandwidth. Tested on a AMD Ryzen 7 PRO 4750U (Renoir). Bug: https://bugzilla.kernel.org/show_bug.cgi?id=206987Signed-off-by:

Fix potential integer overflow by casting actual_calculated_clock_100hz to u64, in order to give the compiler complete information about the proper arithmetic to use. Notice that such variable is used in a context that expects an expression of type u64 (64 bits, unsigned) and the following expression is currently being evaluated using 32-bit arithmetic: actual_calculated_clock_100hz * post_divider Fixes: 7a03fdf6 ("drm/amd/display: fix 64bit division issue on 32bit OS") Addresses-Coverity-ID: 1501691 ("Unintentional integer overflow") Signed-off-by:

This patch is to make the error log more clear for fine grain tuning function, it covers Raven/Raven2/Picasso/Renoir/Vangogh. The fine grain tuning function uses the sysfs file -- pp_od_clk_voltage, but only when another sysfs file -- power_dpm_force_performance_level is switched to "manual" mode, it is allowed to access "pp_od_clk_voltage".

It is possible for ret_vsnprintf to be assigned negative value in error cases. As an unsigned variable, negative values which are stored in their 2's complement form gets treated as a positive number. This will led to treating bad cases as good ones. eg: -1 gets stored as 0xFFFFFFFF on a 32 bit system Signed-off-by:
