From c2740578404b4e46d198de70af1cfd554033d99f Mon Sep 17 00:00:00 2001 From: Andreas Sandberg Date: Tue, 7 Jul 2015 10:03:13 +0100 Subject: ext: Add the NoMali GPU no-simulation library Add revision 9adf9d6e2d889a483a92136c96eb8a434d360561 of NoMali-model from https://github.com/ARM-software/nomali-model. This library implements the register interface of the Mali T6xx/T7xx series GPUs, but doesn't do any rendering. It can be used to hide the effects of software rendering. --- ext/nomali/tests/nomali_test_ints.c | 127 ++++++++++++++++++++++++++++++++++++ 1 file changed, 127 insertions(+) create mode 100644 ext/nomali/tests/nomali_test_ints.c (limited to 'ext/nomali/tests/nomali_test_ints.c') diff --git a/ext/nomali/tests/nomali_test_ints.c b/ext/nomali/tests/nomali_test_ints.c new file mode 100644 index 000000000..54a7083ab --- /dev/null +++ b/ext/nomali/tests/nomali_test_ints.c @@ -0,0 +1,127 @@ +/* + * Copyright (c) 2014-2015 ARM Limited + * All rights reserved + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + * + * Authors: Andreas Sandberg + */ + +#include +#include + +#include "nomali_test_helpers.h" +#include "../lib/mali_midg_regmap.h" + +static void +on_int(nomali_handle_t h, void *usr, nomali_int_t intno, int set) +{ + test_diag("on_int: intno: %i, set: %i", intno, set); + *(int*)usr = !!set; +} + +static void +test_gpu_int(nomali_handle_t h) +{ + nomali_error_t error = NOMALI_E_OK; + int int_triggered = 0; + nomali_callback_t int_callback = { + .type = NOMALI_CALLBACK_INT, + .usr = &int_triggered, + .func.interrupt = on_int, + }; + + nomali_callback_t int_null_callback = { + .type = NOMALI_CALLBACK_INT, + .usr = NULL, + .func.interrupt = NULL, + }; + + /* + * Raise an interrupt without callbacks + */ + E_NOMALI_BAIL(nomali_reg_write(h, + GPU_CONTROL_REG(GPU_IRQ_CLEAR), + GPU_IRQ_REG_ALL)); + + E_NOMALI_BAIL(nomali_reg_write(h, GPU_CONTROL_REG(GPU_IRQ_MASK), + GPU_FAULT)); + + E_NOMALI_BAIL(nomali_reg_write(h, GPU_CONTROL_REG(GPU_IRQ_RAWSTAT), + GPU_FAULT)); + + E_NOMALI_BAIL(nomali_reg_write(h, + GPU_CONTROL_REG(GPU_IRQ_CLEAR), + GPU_IRQ_REG_ALL)); + + /* + * Register callbacks and raise interrupt again. + */ + E_NOMALI_BAIL(nomali_set_callback(h, &int_callback)); + if (int_triggered != 0) { + test_diag("Got spurious interrupt\n"); + test_fail("gpu_int"); + } + + E_NOMALI_BAIL(nomali_reg_write(h, GPU_CONTROL_REG(GPU_IRQ_RAWSTAT), + GPU_FAULT)); + if (int_triggered == 1) { + test_ok("gpu_int"); + } else { + test_fail("gpu_int"); + } + int_triggered = 0; + + + /* + * Register mask interrupts and raise interrupt again. + */ + E_NOMALI_BAIL(nomali_reg_write(h, + GPU_CONTROL_REG(GPU_IRQ_CLEAR), + GPU_IRQ_REG_ALL)); + E_NOMALI_BAIL(nomali_reg_write(h, GPU_CONTROL_REG(GPU_IRQ_MASK), + 0)); + E_NOMALI_BAIL(nomali_reg_write(h, GPU_CONTROL_REG(GPU_IRQ_RAWSTAT), + GPU_FAULT)); + if (int_triggered == 0) { + test_ok("gpu_int_masked"); + } else { + test_fail("gpu_int_maked"); + } + E_NOMALI_BAIL(nomali_reg_write(h, + GPU_CONTROL_REG(GPU_IRQ_CLEAR), + GPU_IRQ_REG_ALL)); + E_NOMALI_BAIL(nomali_set_callback(h, &int_null_callback)); +} + +int +main(int argc, char **argv) +{ + const nomali_config_t cfg = { + .type = NOMALI_GPU_T60X, + .ver_maj = 0, + .ver_min = 1, + .ver_status = 0, + }; + + nomali_handle_t h; + nomali_error_t error = NOMALI_E_OK; + + E_NOMALI_BAIL(nomali_create(&h, &cfg)); + + test_gpu_int(h); + + E_NOMALI_BAIL(nomali_destroy(h)); + + return 0; +} -- cgit v1.2.3
