From 731cd5526e5c732d51307b26e784f454a724a699 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Wed, 17 Dec 2008 10:09:49 -0800 Subject: libdrm: add mode setting files Add mode setting files to libdrm, including xf86drmMode.* and the new drm_mode.h header. Also add a couple of tests to sanity check the kernel interfaces and update code to support them. --- libdrm/Makefile.am | 3 +- libdrm/intel/intel_bufmgr.h | 5 + libdrm/intel/intel_bufmgr_gem.c | 1 + libdrm/xf86drm.c | 44 ++- libdrm/xf86drm.h | 6 + libdrm/xf86drmMode.c | 686 ++++++++++++++++++++++++++++++++++++++++ libdrm/xf86drmMode.h | 258 +++++++++++++++ linux-core/drm_mode.h | 1 + shared-core/Makefile.am | 1 + shared-core/drm.h | 27 ++ shared-core/drm_mode.h | 271 ++++++++++++++++ tests/Makefile.am | 4 + tests/dristat.c | 2 +- tests/modeprint/Makefile | 14 + tests/modeprint/app | Bin 0 -> 16233 bytes tests/modeprint/modeprint.c | 402 +++++++++++++++++++++++ tests/modeprint/test | 1 + tests/modetest/Makefile | 14 + tests/modetest/modetest.c | 449 ++++++++++++++++++++++++++ tests/modetest/test | 2 + 20 files changed, 2179 insertions(+), 12 deletions(-) create mode 100644 libdrm/xf86drmMode.c create mode 100644 libdrm/xf86drmMode.h create mode 120000 linux-core/drm_mode.h create mode 100644 shared-core/drm_mode.h create mode 100644 tests/modeprint/Makefile create mode 100755 tests/modeprint/app create mode 100644 tests/modeprint/modeprint.c create mode 100644 tests/modeprint/test create mode 100644 tests/modetest/Makefile create mode 100644 tests/modetest/modetest.c create mode 100644 tests/modetest/test diff --git a/libdrm/Makefile.am b/libdrm/Makefile.am index a5be36e0..eb63abe1 100644 --- a/libdrm/Makefile.am +++ b/libdrm/Makefile.am @@ -26,9 +26,10 @@ libdrm_la_LDFLAGS = -version-number 2:4:0 -no-undefined AM_CFLAGS = -I$(top_srcdir)/shared-core libdrm_la_SOURCES = xf86drm.c xf86drmHash.c xf86drmRandom.c xf86drmSL.c \ + xf86drmMode.c libdrm_lists.h libdrm_lists.h libdrmincludedir = ${includedir} -libdrminclude_HEADERS = xf86drm.h +libdrminclude_HEADERS = xf86drm.h xf86drmMode.h EXTRA_DIST = ChangeLog TODO diff --git a/libdrm/intel/intel_bufmgr.h b/libdrm/intel/intel_bufmgr.h index f134f169..e8c2e063 100644 --- a/libdrm/intel/intel_bufmgr.h +++ b/libdrm/intel/intel_bufmgr.h @@ -66,6 +66,11 @@ struct _drm_intel_bo { /** Buffer manager context associated with this buffer object */ drm_intel_bufmgr *bufmgr; + + /** + * MM-specific handle for accessing object + */ + int handle; }; drm_intel_bo *drm_intel_bo_alloc(drm_intel_bufmgr *bufmgr, const char *name, diff --git a/libdrm/intel/intel_bufmgr_gem.c b/libdrm/intel/intel_bufmgr_gem.c index e5a1375e..9605cc7c 100644 --- a/libdrm/intel/intel_bufmgr_gem.c +++ b/libdrm/intel/intel_bufmgr_gem.c @@ -351,6 +351,7 @@ drm_intel_gem_bo_alloc(drm_intel_bufmgr *bufmgr, const char *name, ret = ioctl(bufmgr_gem->fd, DRM_IOCTL_I915_GEM_CREATE, &create); bo_gem->gem_handle = create.handle; + bo_gem->bo.handle = bo_gem->gem_handle; if (ret != 0) { free(bo_gem); return NULL; diff --git a/libdrm/xf86drm.c b/libdrm/xf86drm.c index c36f1964..0b5d31fe 100644 --- a/libdrm/xf86drm.c +++ b/libdrm/xf86drm.c @@ -87,6 +87,9 @@ #define DRM_MSG_VERBOSITY 3 +#define DRM_NODE_CONTROL 0 +#define DRM_NODE_RENDER 1 + static drmServerInfoPtr drm_server_info; void drmSetServerInfo(drmServerInfoPtr info) @@ -174,7 +177,7 @@ static char *drmStrdup(const char *s) /** * Call ioctl, restarting if it is interupted */ -static int +int drmIoctl(int fd, unsigned long request, void *arg) { int ret; @@ -277,7 +280,7 @@ static int drmMatchBusID(const char *id1, const char *id2) * special file node with the major and minor numbers specified by \p dev and * parent directory if necessary and was called by root. */ -static int drmOpenDevice(long dev, int minor) +static int drmOpenDevice(long dev, int minor, int type) { stat_t st; char buf[64]; @@ -287,7 +290,7 @@ static int drmOpenDevice(long dev, int minor) uid_t user = DRM_DEV_UID; gid_t group = DRM_DEV_GID, serv_group; - sprintf(buf, DRM_DEV_NAME, DRM_DIR_NAME, minor); + sprintf(buf, type ?
