this patch adds libdrm_exynos helper layer that inclues some intefaces for exynos specific gem and virtual display driver and also adds exynos module name to modtest and vbltest. Changelog v2: - fixed exynos broken ioctl. the pointer of uint64_t *edid should be removed. - removed unnecessary definitions. - added drm prime interfaces. this feature is used to share a buffer between drivers or memory managers and for this, please, refer to below links: http://www.mjmwired.net/kernel/Documentation/dma-buf-sharing.txt http://lwn.net/Articles/488664/ this patch is based on a link below: git://anongit.freedesktop.org/mesa/drm commit id: d72a44c7c4f5eea9c1e5bb0c36cb9e0224b9ca22 Reviewed-by: Rob Clark <rob@xxxxxx> Reviewed-by: Alex Deucher <alexander.deucher@xxxxxxx> Signed-off-by: Inki Dae <inki.dae@xxxxxxxxxxx> Signed-off-by: Kyungmin Park <kyungmin.park@xxxxxxxxxxx> --- Makefile.am | 6 +- configure.ac | 13 ++ exynos/Makefile.am | 22 +++ exynos/exynos_drm.c | 396 ++++++++++++++++++++++++++++++++++++++++++++ exynos/exynos_drm.h | 149 +++++++++++++++++ exynos/exynos_drmif.h | 88 ++++++++++ exynos/libdrm_exynos.pc | 11 ++ exynos/libdrm_exynos.pc.in | 11 ++ tests/modetest/modetest.c | 2 +- tests/vbltest/vbltest.c | 2 +- 10 files changed, 697 insertions(+), 3 deletions(-) create mode 100644 exynos/Makefile.am create mode 100644 exynos/exynos_drm.c create mode 100644 exynos/exynos_drm.h create mode 100644 exynos/exynos_drmif.h create mode 100644 exynos/libdrm_exynos.pc create mode 100644 exynos/libdrm_exynos.pc.in diff --git a/Makefile.am b/Makefile.am index 4f625a1..256a8cc 100644 --- a/Makefile.am +++ b/Makefile.am @@ -45,7 +45,11 @@ if HAVE_OMAP OMAP_SUBDIR = omap endif -SUBDIRS = . $(LIBKMS_SUBDIR) $(INTEL_SUBDIR) $(NOUVEAU_SUBDIR) $(RADEON_SUBDIR) $(OMAP_SUBDIR) tests include +if HAVE_EXYNOS +EXYNOS_SUBDIR = exynos +endif + +SUBDIRS = . $(LIBKMS_SUBDIR) $(INTEL_SUBDIR) $(NOUVEAU_SUBDIR) $(RADEON_SUBDIR) $(OMAP_SUBDIR) $(EXYNOS_SUBDIR) tests include libdrm_la_LTLIBRARIES = libdrm.la libdrm_ladir = $(libdir) diff --git a/configure.ac b/configure.ac index 6a1d98e..f832201 100644 --- a/configure.ac +++ b/configure.ac @@ -88,6 +88,11 @@ AC_ARG_ENABLE(omap-experimental-api, [Enable support for OMAP's experimental API (default: disabled)]), [OMAP=$enableval], [OMAP=no]) +AC_ARG_ENABLE(exynos-experimental-api, + AS_HELP_STRING([--enable-exynos-experimental-api], + [Enable support for EXYNOS's experimental API (default: disabled)]), + [EXYNOS=$enableval], [EXYNOS=no]) + dnl =========================================================================== dnl check compiler flags AC_DEFUN([LIBDRM_CC_TRY_FLAG], [ @@ -191,6 +196,11 @@ if test "x$OMAP" = xyes;
