Now we want secure guests which means devices can # only access certain areas of guest physical memory; we are going to # use SWIOTLB for this purpose. # # This allows SWIOTLB for pseries. By default there is no change in # behavior. # # This enables SWIOTLB when the "swiotlb" kernel parameter is set to # "force". # # With the SWIOTLB enabled, the kernel creates a directly mapped DMA # window (using the usual DDW mechanism) and implements SWIOTLB on top # of that. # # Signed-off-by: Alexey Kardashevskiy # Signed-off-by: Michael Ellerman # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 41a808618879dc28fb0a94b08db4b55790eb7827 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc8540_ads_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc8540_ads_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc8540_ads_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x4b00e0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x49fa20) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.2.0-rc2-g41a808618879 Created: Tue Jul 2 01:04:52 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2433117 Bytes = 2376.09 KiB = 2.32 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.2.0-rc2-g41a808618879 Created: Tue Jul 2 01:04:52 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2461508 Bytes = 2403.82 KiB = 2.35 MiB Load Address: 00500000 Entry Point: 005002a4 Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_mpc8540_ads_defconfig_powerpc-gcc5 # Build took: 0:00:40.928763
