From 273f7d84049ad3c204571206b060d403e1ff2f94 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Wed, 9 May 2018 07:52:53 -0400 Subject: [PATCH] freedreno: fence should hold a ref to pipe Since the fence can outlive the context, and all it really needs to wait on a fence is the pipe, use the new fd_pipe reference counting to hold a ref to the pipe and drop the ctx pointer. This fixes a crash seen with (for example) glmark2: #0 fd_pipe_wait_timeout (pipe=0xbf48678b3cd7b32b, timestamp=0, timeout=18446744073709551615) at freedreno_pipe.c:101 #1 0x0000ffffbdf75914 in fd_fence_finish (pscreen=0x561110, ctx=0x0, fence=0xc55c10, timeout=18446744073709551615) at ../src/gallium/drivers/freedreno/freedreno_fence.c:96 #2 0x0000ffffbde154e4 in dri_flush (cPriv=0xb1ff80, dPriv=0x556660, flags=3, reason=__DRI2_THROTTLE_SWAPBUFFER) at ../src/gallium/state_trackers/dri/dri_drawable.c:569 #3 0x0000ffffbecd8b44 in loader_dri3_flush (draw=0x558a28, flags=3, throttle_reason=__DRI2_THROTTLE_SWAPBUFFER) at ../src/loader/loader_dri3_helper.c:656 #4 0x0000ffffbecbc36c in glx_dri3_flush_drawable (draw=0x558a28, flags=3) at ../src/glx/dri3_glx.c:132 #5 0x0000ffffbecd91e8 in loader_dri3_swap_buffers_msc (draw=0x558a28, target_msc=0, divisor=0, remainder=0, flush_flags=3, force_copy=false) at ../src/loader/loader_dri3_helper.c:827 #6 0x0000ffffbecbcfc4 in dri3_swap_buffers (pdraw=0x5589f0, target_msc=0, divisor=0, remainder=0, flush=1) at ../src/glx/dri3_glx.c:587 #7 0x0000ffffbec98218 in glXSwapBuffers (dpy=0x502bb0, drawable=2097154) at ../src/glx/glxcmds.c:840 #8 0x000000000040994c in CanvasGeneric::update (this=0xfffffffff400) at ../src/canvas-generic.cpp:114 #9 0x0000000000411594 in MainLoop::step (this=this@entry=0x5728f0) at ../src/main-loop.cpp:108 #10 0x0000000000409498 in do_benchmark (canvas=...) at ../src/main.cpp:117 #11 0x00000000004071b0 in main (argc=, argv=) at ../src/main.cpp:210 Signed-off-by: Rob Clark --- configure.ac | 2 +- meson.build | 2 +- src/gallium/drivers/freedreno/freedreno_fence.c | 7 ++++--- 3 files changed, 6 insertions(+), 5 deletions(-) diff --git a/configure.ac b/configure.ac index a9babec..5f5e760 100644 --- a/configure.ac +++ b/configure.ac @@ -78,7 +78,7 @@ LIBDRM_AMDGPU_REQUIRED=2.4.91 LIBDRM_INTEL_REQUIRED=2.4.75 LIBDRM_NVVIEUX_REQUIRED=2.4.66 LIBDRM_NOUVEAU_REQUIRED=2.4.66 -LIBDRM_FREEDRENO_REQUIRED=2.4.91 +LIBDRM_FREEDRENO_REQUIRED=2.4.92 LIBDRM_ETNAVIV_REQUIRED=2.4.89 dnl Versions for external dependencies diff --git a/meson.build b/meson.build index e52b4a5..9a538e9 100644 --- a/meson.build +++ b/meson.build @@ -1041,7 +1041,7 @@ _drm_amdgpu_ver = '2.4.91' _drm_radeon_ver = '2.4.71' _drm_nouveau_ver = '2.4.66' _drm_etnaviv_ver = '2.4.89' -_drm_freedreno_ver = '2.4.91' +_drm_freedreno_ver = '2.4.92' _drm_intel_ver = '2.4.75' _drm_ver = '2.4.75' diff --git a/src/gallium/drivers/freedreno/freedreno_fence.c b/src/gallium/drivers/freedreno/freedreno_fence.c index 1925f72..c4e2022 100644 --- a/src/gallium/drivers/freedreno/freedreno_fence.c +++ b/src/gallium/drivers/freedreno/freedreno_fence.c @@ -41,7 +41,7 @@ struct pipe_fence_handle { * fence_fd become valid and the week reference is dropped. */ struct fd_batch *batch; - struct fd_context *ctx; + struct fd_pipe *pipe; struct fd_screen *screen; int fence_fd; uint32_t timestamp; @@ -68,6 +68,7 @@ static void fd_fence_destroy(struct pipe_fence_handle *fence) { if (fence->fence_fd != -1) close(fence->fence_fd); + fd_pipe_del(fence->pipe); FREE(fence); } @@ -93,7 +94,7 @@ boolean fd_fence_finish(struct pipe_screen *pscreen, return ret == 0; } - if (fd_pipe_wait_timeout(fence->ctx->pipe, fence->timestamp, timeout)) + if (fd_pipe_wait_timeout(fence->pipe, fence->timestamp, timeout)) return false; return true; @@ -111,7 +112,7 @@ static struct pipe_fence_handle * fence_create(struct fd_context *ctx, pipe_reference_init(&fence->reference, 1); fence->batch = batch; - fence->ctx = ctx; + fence->pipe = fd_pipe_ref(ctx->pipe); fence->screen = ctx->screen; fence->timestamp = timestamp; fence->fence_fd = fence_fd; -- 2.7.4
