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 <aik@ozlabs.ru> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 41a808618879dc28fb0a94b08db4b55790eb7827 # < make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_obs600_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- 40x/obs600_defconfig # make -s -j 80 ARCH=powerpc O=/kisskb/build/powerpc-next_40x_obs600_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:331:21: note: 'pdeo' was declared here /kisskb/src/drivers/base/regmap/regmap.c: In function 'regmap_raw_read': /kisskb/src/drivers/base/regmap/regmap.c:2589:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/base/regmap/regmap.c: In function '_regmap_raw_write': /kisskb/src/drivers/base/regmap/regmap.c:1850:6: warning: 'ret' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x4c9b18) 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 00:42:58 2019 Image Type: PowerPC Linux Multi-File Image (gzip compressed) Data Size: 2432794 Bytes = 2375.78 KiB = 2.32 MiB Load Address: 00000000 Entry Point: 00000000 Contents: Image 0: 2425907 Bytes = 2369.05 KiB = 2.31 MiB Image 1: 3 Bytes = 0.00 KiB = 0.00 MiB Image 2: 6866 Bytes = 6.71 KiB = 0.01 MiB Completed OK # rm -rf /kisskb/build/powerpc-next_40x_obs600_defconfig_powerpc-gcc4.6 # Build took: 0:00:35.487026
