From b312d8ca3a7cebe19941d969a51f2b7f899b81e2 Mon Sep 17 00:00:00 2001 From: Christian König Date: Wed, 14 Nov 2018 16:11:06 +0100 Subject: dma-buf: make fence sequence numbers 64 bit v2 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For a lot of use cases we need 64bit sequence numbers. Currently drivers overload the dma_fence structure to store the additional bits. Stop doing that and make the sequence number in the dma_fence always 64bit. For compatibility with hardware which can do only 32bit sequences the comparisons in __dma_fence_is_later only takes the lower 32bits as significant when the upper 32bits are all zero. v2: change the logic in __dma_fence_is_later Signed-off-by: Christian König Reviewed-by: Chunming Zhou Link: https://patchwork.freedesktop.org/patch/266927/ --- drivers/gpu/drm/amd/amdgpu/amdgpu_sa.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/gpu/drm/amd/amdgpu/amdgpu_sa.c') diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_sa.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_sa.c index 12f2bf97611f..bfaf5c6323be 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_sa.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_sa.c @@ -388,7 +388,7 @@ void amdgpu_sa_bo_dump_debug_info(struct amdgpu_sa_manager *sa_manager, soffset, eoffset, eoffset - soffset); if (i->fence) - seq_printf(m, " protected by 0x%08x on context %llu", + seq_printf(m, " protected by 0x%016llx on context %llu", i->fence->seqno, i->fence->context); seq_printf(m, "\n"); -- cgit
