SP scheduler hangs in process mode performance test due to global data structure were not created in shared memory region.
Signed-off-by: Yi He <yi...@linaro.org> --- Fixes: https://bugs.linaro.org/show_bug.cgi?id=2464 After Petri/Matias' pool/ordered queue patchsets, SP scheduler can pass validation test suite, this patch fixes the last issue as reported and SP scheduler can pass make check after then. platform/linux-generic/odp_schedule_sp.c | 89 ++++++++++++++++++++------------ 1 file changed, 56 insertions(+), 33 deletions(-) diff --git a/platform/linux-generic/odp_schedule_sp.c b/platform/linux-generic/odp_schedule_sp.c index 76d1357..d9f861f 100644 --- a/platform/linux-generic/odp_schedule_sp.c +++ b/platform/linux-generic/odp_schedule_sp.c @@ -9,6 +9,7 @@ #include <odp/api/thread.h> #include <odp/api/time.h> #include <odp/api/schedule.h> +#include <odp/api/shared_memory.h> #include <odp_schedule_if.h> #include <odp_debug_internal.h> #include <odp_align_internal.h> @@ -85,6 +86,7 @@ typedef struct { sched_cmd_t pktio_cmd[NUM_PKTIO];
