From 32f16b0b1e1ddaa7b7ab318d9b8323a941887384 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 30 Jan 2019 16:22:02 -0800 Subject: [PATCH] v3d: Clear the GMP on initialization of the simulator. Otherwise, we might have pages accessible that shouldn't be and miss out on errors. This is unlikely for most tests since v3d_hw_get_mem() is big enough that it'll be a freshly zeroed mmap, but if screens are destroyed and recreated then we'd be reusing the old v3d_hw_get_mem() contents. --- src/gallium/drivers/v3d/v3d_simulator.c | 1 + 1 file changed, 1 insertion(+) diff --git a/src/gallium/drivers/v3d/v3d_simulator.c b/src/gallium/drivers/v3d/v3d_simulator.c index b0b4c103623..c5ddaa03103 100644 --- a/src/gallium/drivers/v3d/v3d_simulator.c +++ b/src/gallium/drivers/v3d/v3d_simulator.c @@ -580,6 +580,7 @@ v3d_simulator_init(struct v3d_screen *screen) sim_file->gmp = u_mmAllocMem(sim_state.heap, 8096, GMP_ALIGN2, 0); sim_file->gmp_vaddr = (sim_state.mem + sim_file->gmp->ofs - sim_state.mem_base); + memset(sim_file->gmp_vaddr, 0, 8096); } void -- 2.30.2
