From ae452e327aa8dab739ca521e924a9ac9fcc506cf Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 2 Jul 2013 11:24:57 +0100 Subject: [PATCH] tests/gem_(linear|tiled)_blits: Repeat whilst being interrupted Since these two tests exercise a working set larger than aperture, they require stalls which are prone to being interrupted - so interrupt them and check that everything still works. --- tests/gem_linear_blits.c | 60 ++++++++++++++++++++++++--------------- tests/gem_tiled_blits.c | 73 ++++++++++++++++++++++++++++-------------------- 2 files changed, 80 insertions(+), 53 deletions(-) diff --git a/tests/gem_linear_blits.c b/tests/gem_linear_blits.c index ec2dc56..4a6e506 100644 --- a/tests/gem_linear_blits.c +++ b/tests/gem_linear_blits.c @@ -176,30 +176,11 @@ check_bo(int fd, uint32_t handle, uint32_t val) } } -int main(int argc, char **argv) +static void run_test(int fd, int count) { uint32_t *handle, *start_val;
