| | | | | | | | | | | | | | [Why & How] The only reason we have the DCN config is for floating point support. Rename it to make that clear and (hopefully) avoid misuse of the config in the future.

* drm/amd/display: Drop FPU flags from dcn32_clk_mgrRodrigo Siqueira2022-07-251-25/+0
| | | | | | | | | | | | | We are working to isolate FPU operations inside the DML folder, and the file dcn32_clk_mgr has some of these operations. This commit moves the FPU operations inside the clock manager and creates the dcn32_fpu file to aggregate those operations. Note that there is no functional change ere, just moving code from one part to another.

* drm/amdgpu/display: drop DCN support for aarch64Alex Deucher2021-01-061-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | From Ard: "Simply disabling -mgeneral-regs-only left and right is risky, given that the standard AArch64 ABI permits the use of FP/SIMD registers anywhere, and GCC is known to use SIMD registers for spilling, and may invent other uses of the FP/SIMD register file that have nothing to do with the floating point code in question. Note that putting kernel_neon_begin() and kernel_neon_end() around the code that does use FP is not sufficient here, the problem is in all the other code that may be emitted with references to SIMD registers in it. So the only way to do this properly is to put all floating point code in a separate compilation unit, and only compile that unit with -mgeneral-regs-only." Disable support until the code can be properly refactored to support this properly on aarch64.

* amdgpu: Prevent build errors regarding soft/hard-float FP ABI tagsDaniel Kolesa2020-02-111-0/+6
| | | | | | | | | | | | | | | | | On PowerPC, the compiler will tag object files with whether they use hard or soft float FP ABI and whether they use 64 or 128-bit long double ABI. On systems with 64-bit long double ABI, a tag will get emitted whenever a double is used, as on those systems a long double is the same as a double. This will prevent linkage as other files are being compiled with hard-float. On ppc64, this code will never actually get used for the time being, as the only currently existing hardware using it are the Renoir APUs. Therefore, until this is testable and can be fixed properly, at least make sure the build will not fail.
