X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=16985eb308ea063025874eb1094269b9b3ed4656;p=mesa.git vc4: Switch to using the libdrm-provided vc4_drm.h. The required version is set to .69 for the getparam ioctl that will be used in the next commit. --- diff --git a/configure.ac b/configure.ac index 6ea1f2c6a2f..3799d8dca30 100644 --- a/configure.ac +++ b/configure.ac @@ -75,6 +75,7 @@ LIBDRM_INTEL_REQUIRED=2.4.61 LIBDRM_NVVIEUX_REQUIRED=2.4.66 LIBDRM_NOUVEAU_REQUIRED=2.4.66 LIBDRM_FREEDRENO_REQUIRED=2.4.67 +LIBDRM_VC4_REQUIRED=2.4.69 DRI2PROTO_REQUIRED=2.6 DRI3PROTO_REQUIRED=1.0 PRESENTPROTO_REQUIRED=1.0 @@ -2467,6 +2468,7 @@ if test -n "$with_gallium_drivers"; then ;; xvc4) HAVE_GALLIUM_VC4=yes + PKG_CHECK_MODULES([VC4], [libdrm_vc4 >= $LIBDRM_VC4_REQUIRED]) gallium_require_drm "vc4" gallium_require_drm_loader diff --git a/src/gallium/drivers/vc4/Makefile.am b/src/gallium/drivers/vc4/Makefile.am index caa5059fbd3..de82c2c515f 100644 --- a/src/gallium/drivers/vc4/Makefile.am +++ b/src/gallium/drivers/vc4/Makefile.am @@ -29,6 +29,7 @@ endif AM_CFLAGS = \ -I$(top_builddir)/src/compiler/nir \ $(LIBDRM_CFLAGS) \ + $(VC4_CFLAGS) \ $(GALLIUM_DRIVER_CFLAGS) \ $(SIM_CFLAGS) \ $() @@ -36,5 +37,5 @@ AM_CFLAGS = \ noinst_LTLIBRARIES = libvc4.la libvc4_la_SOURCES = $(C_SOURCES) -libvc4_la_LIBADD = $(SIM_LIB) +libvc4_la_LIBADD = $(SIM_LIB) $(VC4_LIBS) libvc4_la_LDFLAGS = $(SIM_LDFLAGS) diff --git a/src/gallium/drivers/vc4/vc4_drm.h b/src/gallium/drivers/vc4/vc4_drm.h deleted file mode 100644 index 110c783e5fd..00000000000 --- a/src/gallium/drivers/vc4/vc4_drm.h +++ /dev/null @@ -1,279 +0,0 @@ -/* - * Copyright © 2014-2015 Broadcom - * - * 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.
