Subject: [PATCH 0/3] riscv: Add kernel-mode FPU support for amdgpu
Date: Tue, 21 Nov 2023 19:05:12 -0800 [thread overview]
Message-ID: <20231122030621.3759313-1-samuel.holland@sifive.com> (raw)
This series allows using newer AMD GPUs (e.g. Navi) on RISC-V boards
such as SiFive's HiFive Unmatched. Those GPUs need CONFIG_DRM_AMD_DC_FP
to initialize, which requires kernel-mode FPU support.
I'm sending these patches as one series so there is a user along with
the infrastructure being added. I assume patch 3 would be merged
separately, after patches 1-2 are merged.
Samuel Holland (3):
riscv: Add support for kernel-mode FPU
riscv: Factor out riscv-march-y to a separate Makefile
drm/amd/display: Support DRM_AMD_DC_FP on RISC-V
