From 07e99d9fb491d625034fc21e3f2d631acce341bf Mon Sep 17 00:00:00 2001 From: Thomas White Date: Sun, 2 Aug 2009 22:33:34 +0100 Subject: Add GEM mmap() and KMS tests 'gdrm-gem-mmap' creates a GEM object, mmap()s it, and tests access. 'gdrm-kms-addfb' creates a GEM object, switches the active framebuffer to use it, and writes random colours to it via memory mapped access. --- Makefile | 13 +++- drmtest.c | 86 +++++++++++++++++++++++++++ drmtest.h | 24 ++++++++ gdrm-gem-mmap.c | 150 +++++++++++++++++++++++++++++++++++++++++++++++ gdrm-kms-addfb.c | 176 +++++++++++++++++++++++++++++++++++++++++++++++++++++++ 5 files changed, 447 insertions(+), 2 deletions(-) create mode 100644 drmtest.c create mode 100644 drmtest.h create mode 100644 gdrm-gem-mmap.c create mode 100644 gdrm-kms-addfb.c diff --git a/Makefile b/Makefile index bd710f8..3859a82 100644 --- a/Makefile +++ b/Makefile @@ -2,7 +2,8 @@ CFLAGS=-g -W -Wall LIBS=-lX11 -lXext -ldrm -ldrm_glamo CC=gcc -default: gdri-cmdq-submission gdri-mem-manager gdri-buf-cmdq +default: gdri-cmdq-submission gdri-mem-manager gdri-buf-cmdq gdrm-gem-mmap \ + gdrm-kms-addfb .c.o: $(CC) -c ${CFLAGS} ${CROSS_CFLAGS} $*.c @@ -16,14 +17,22 @@ gdri-mem-manager: gdri-mem-manager.o dri2.o utils.o gdri-buf-cmdq: gdri-buf-cmdq.o dri2.o utils.o $(CC) gdri-buf-cmdq.o dri2.o utils.o -o gdri-buf-cmdq ${LIBS} +gdrm-gem-mmap: gdrm-gem-mmap.o drmtest.o + $(CC) gdrm-gem-mmap.o drmtest.o -o gdrm-gem-mmap ${LIBS} + +gdrm-kms-addfb: gdrm-kms-addfb.o drmtest.o + $(CC) gdrm-kms-addfb.o drmtest.o -o gdrm-kms-addfb ${LIBS} + clean: rm -rf dri2.o gdri-cmdq-submission.o utils.o gdri-cmdq-submission \ - gdri-mem-manager gdri-buf-cmdq + gdri-mem-manager gdri-buf-cmdq gdrm-gem-mmap install: install -d -m 755 ${PREFIX}/bin install -m 755 gdri-cmdq-submission ${PREFIX}/bin install -m 755 gdri-mem-manager ${PREFIX}/bin install -m 755 gdri-buf-cmdq ${PREFIX}/bin + install -m 755 gdrm-gem-mmap ${PREFIX}/bin + install -m 755 gdrm-kms-addfb ${PREFIX}/bin .PHONY: clean install default diff --git a/drmtest.c b/drmtest.c new file mode 100644 index 0000000..d053865 --- /dev/null +++ b/drmtest.c @@ -0,0 +1,86 @@ +/* + * Copyright © 2007 Intel Corporation + * + * Permission is hereby granted, free of charge, to any person obtaining a + * copy of this software and associated documentation files (the "Software"), + * to deal in the Software without restriction, including without limitation + * the rights to use, copy, modify, merge, publish, distribute, sublicense, + * and/or sell copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice (including the next + * paragraph) shall be included in all copies or substantial portions of the + * Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
