2023-04-11powerpc/64: Always build with 128-bit long doubleMichael Ellerman
The amdgpu driver builds some of its code with hard-float enabled, whereas the rest of the kernel is built with soft-float. When building with 64-bit long double, if soft-float and hard-float objects are linked together, the build fails due to incompatible ABI tags. In the past there have been build errors in the amdgpu driver caused by this, some of those were due to bad intermingling of soft & hard-float code, but those issues have now all been fixed since commit 58ddbecb14c7 ("drm/amd/display: move remaining FPU code to dml folder"). However it's still possible for soft & hard-float objects to end up linked together, if the amdgpu driver is built-in to the kernel along with the test_emulate_step.c code, which uses soft-float. That happens in an allyesconfig build. Currently those build errors are avoided because the amdgpu driver is gated on 128-bit long double being enabled. But that's not a detail the amdgpu driver should need to be aware of, and if another driver starts using hard-float the same problem would occur. All versions of the 64-bit ABI specify that long-double is 128-bits. However some compilers, notably the kernel.org ones, are built to use 64-bit long double by default. Apart from this issue of soft vs hard-float, the kernel doesn't care what size long double is. In particular the kernel using 128-bit long double doesn't impact userspace's ability to use 64-bit long double, as musl does. So always build the 64-bit kernel with 128-bit long double. That should avoid any build errors due to the incompatible ABI tags. Excluding the code that uses soft/hard-float, the vmlinux is identical with/without the flag. It does mean any code which is incorrectly intermingling soft & hard-float code will build without error, so those bugs will need to be caught by testing rather than at build time.

2022-11-30drm/amdgpu: temporarily disable broken Clang builds due to blown stack-frameLee Jones
Patch series "Fix a bunch of allmodconfig errors", v2. Since b339ec9c229aa ("kbuild: Only default to -Werror if COMPILE_TEST") WERROR now defaults to COMPILE_TEST meaning that it's enabled for allmodconfig builds. This leads to some interesting build failures when using Clang, each resolved in this set. With this set applied, I am able to obtain a successful allmodconfig Arm build. This patch (of 2): calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64) architectures built with Clang (all released versions), whereby the stack frame gets blown up to well over 5k. This would cause an immediate kernel panic on most architectures. We'll revert this when the following bug report has been resolved: https://github.com/llvm/llvm-project/issues/41896.

2022-07-26drm/amdgpu: Re-enable DCN for 64-bit powerpcMichael Ellerman
Commit d11219ad53dc ("amdgpu: disable powerpc support for the newer display engine") disabled the DCN driver for all of powerpc due to unresolved build failures with some compilers. Further digging shows that the build failures only occur with compilers that default to 64-bit long double. Both the ppc64 and ppc64le ABIs define long double to be 128-bits, but there are compilers in the wild that default to 64-bits. The compilers provided by the major distros (Fedora, Ubuntu) default to 128-bits and are not affected by the build failure. There is a compiler flag to force 128-bit long double, which may be the correct long term fix, but as an interim fix only allow building the DCN driver if long double is 128-bits by default. The bisection in commit d11219ad53dc must have gone off the rails at some point, the build failure occurs all the way back to the original commit that enabled DCN support on powerpc, at least with some toolchains.

The new display engine uses floating point math, which is not supported by KCOV. Commit 9d1d02ff3678 ("drm/amd/display: Don't build DCN1 when kcov is enabled") tried to work around the problem by disabling CONFIG_DRM_AMD_DC_DCN if KCOV_INSTRUMENT_ALL and KCOV_ENABLE_COMPARISONS are enabled. The result is that KCOV can not be enabled on systems which require this display engine. A much simpler and less invasive solution is to disable KCOV selectively when compiling the display enagine while keeping it enabled for the rest of the kernel.

2022-07-14amdgpu: disable powerpc support for the newer display engineLinus Torvalds
The DRM_AMD_DC_DCN display engine support (Raven, Navi, and newer) has not been building cleanly on powerpc and causes link errors due to mixing hard- and soft-float object files: powerpc64-linux-ld: drivers/gpu/drm/amd/amdgpu/../display/dc/dml/display_mode_lib.o uses hard float, drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o uses soft float powerpc64-linux-ld: failed to merge target specific data of file drivers/gpu/drm/amd/amdgpu/../display/dc/dcn31/dcn31_resource.o [..] and while patches are floating around, it's not exactly obvious what is going on. The problem bisects to commit 41b7a347bf14 ("powerpc: Book3S 64-bit outline-only KASAN support") but that is probably more about changing config variables than the fundamental cause. Despite the bisection result, a more directly related commit seems to be 26f4712aedbd ("drm/amd/display: move FPU related code from dcn31 to dml/dcn31 folder"). It's probably a combination of the two. This has been going on since the merge window, without any final word. So instead of blindly applying patches that may or may not be the right thing, let's disable this for now. As Michael Ellerman says: "IIUIC this code was never enabled on ppc before, so disabling it seems like a reasonable fix to get the build clean" and once we have more actual feedback (and find any potential users) we can always re-enable it with the patch that fixes the issues and back-port as necessary.

2021-01-05drm/amdgpu/display: drop DCN support for aarch64Alex Deucher
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.

2019-07-11drm/amd/display: Add drm_audio_component support to amdgpu_dmNicholas Kazlauskas
[Why] The drm_audio_component can be used to give pin ELD notifications directly to the sound driver. This fixes audio endpoints disappearing due to missing unsolicited notifications. [How] Send the notification via the audio component whenever we enable or disable audio state on a stream. This matches what i915 does with their drm_audio_component and what Takashi Iwai's proposed hack for radeon/amdpgu did. This is a bit delayed in when the notification actually occurs, however. We wait until after all the programming is complete rather than sending the notification mid sequence. Particular care is needed for the get ELD callback since it can happen outside the locking and fencing DRM does for atomic commits.
