[1] I don't remember the full details, but semantics of the vmap/vunmap for dma-bufs were not compatible IIRC. And the resolution was a redesign of the API.
I posted a patchset with a new interface at [1]. Best regards Thomas[1] https://lore.kernel.org/dri-devel/20201209142527.26415-1-tzimmermann@xxxxxxx/
If that has changed, I'd be happy to see this patch merged. Otherwise, it should better not be taken.Best regards Thomas [1] https://patchwork.freedesktop.org/patch/400054/?series=83765&rev=1-- v1->v2: - rename amdgpu_align_pitch as amdgpu_gem_align_pitch to align with other APIs from the same file (Alex) --- drivers/gpu/drm/amd/amdgpu/Makefile | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 12 +- drivers/gpu/drm/amd/amdgpu/amdgpu_display.c | 11 +- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 13 + drivers/gpu/drm/amd/amdgpu/amdgpu_fb.c | 388 -------------------- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c | 30 +- drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h | 20 - 7 files changed, 50 insertions(+), 426 deletions(-) delete mode 100644 drivers/gpu/drm/amd/amdgpu/amdgpu_fb.cdiff --git a/drivers/gpu/drm/amd/amdgpu/Makefile b/drivers/gpu/drm/amd/amdgpu/Makefileindex 8d0748184a14..73a2151ee43f 100644 --- a/drivers/gpu/drm/amd/amdgpu/Makefile +++ b/drivers/gpu/drm/amd/amdgpu/Makefile @@ -45,7 +45,7 @@ amdgpu-y += amdgpu_device.o amdgpu_kms.o \ amdgpu_atombios.o atombios_crtc.o amdgpu_connectors.o \atom.o amdgpu_fence.o amdgpu_ttm.o amdgpu_object.o amdgpu_gart.o \amdgpu_encoders.o amdgpu_display.o amdgpu_i2c.o \ - amdgpu_fb.o amdgpu_gem.o amdgpu_ring.o \ + amdgpu_gem.o amdgpu_ring.o \ amdgpu_cs.o amdgpu_bios.o amdgpu_benchmark.o amdgpu_test.o \ atombios_dp.o amdgpu_afmt.o amdgpu_trace_points.o \ atombios_encoders.o amdgpu_sa.o atombios_i2c.o \diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.cindex 682d459e992a..bcc308b7f826 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_device.c @@ -3695,8 +3695,6 @@ int amdgpu_device_init(struct amdgpu_device *adev, /* Get a log2 for easy divisions. */ adev->mm_stats.log2_max_MBps = ilog2(max(1u, max_MBps));
