Author: Eric Anholt <[email protected]> Date: Tue Aug 2 15:01:59 2016 -0700 vc4: Tell valgrind about BO allocations from mmap time to destroy. This helps in debugging memory pressure. It would be nice if we could tell valgrind about it all the way from allocation time to destroy, but we need a pointer to hand to VALGRIND_MALLOCLIKE_BLOCK. --- src/gallium/drivers/vc4/Makefile.am | 1 + src/gallium/drivers/vc4/vc4_bufmgr.c | 10 ++++++++++ 2 files changed, 11 insertions(+) diff --git a/src/gallium/drivers/vc4/Makefile.am b/src/gallium/drivers/vc4/Makefile.am index de82c2c..19fc387 100644 --- a/src/gallium/drivers/vc4/Makefile.am +++ b/src/gallium/drivers/vc4/Makefile.am @@ -32,6 +32,7 @@ AM_CFLAGS = \ $(VC4_CFLAGS) \ $(GALLIUM_DRIVER_CFLAGS) \ $(SIM_CFLAGS) \ + $(VALGRIND_CFLAGS) \ $() noinst_LTLIBRARIES = libvc4.la diff --git a/src/gallium/drivers/vc4/vc4_bufmgr.c b/src/gallium/drivers/vc4/vc4_bufmgr.c index f6bacfd..cf6a511 100644 --- a/src/gallium/drivers/vc4/vc4_bufmgr.c +++ b/src/gallium/drivers/vc4/vc4_bufmgr.c @@ -35,6 +35,14 @@ #include "vc4_context.h" #include "vc4_screen.h" +#ifdef HAVE_VALGRIND +#include <valgrind.h> +#include <memcheck.h> +#define VG(x) x +#else +#define VG(x) +#endif + static bool dump_stats = false; static void @@ -209,6 +217,7 @@ vc4_bo_free(struct vc4_bo *bo) } #endif munmap(bo->map, bo->size); + VG(VALGRIND_FREELIKE_BLOCK(bo->map, 0)); } struct drm_gem_close c; @@ -618,6 +627,7 @@ vc4_bo_map_unsynchronized(struct vc4_bo *bo) bo->handle, (long long)offset, bo->size); abort(); } + VG(VALGRIND_MALLOCLIKE_BLOCK(bo->map, bo->size, 0, false)); return bo->map; } _______________________________________________ mesa-commit mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-commit
