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/ia64-linux/bin/ia64-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux-ld --version # < git log --format=%s --max-count=1 41a808618879dc28fb0a94b08db4b55790eb7827 # < make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-next_ia64-defconfig_ia64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux- defconfig # make -s -j 24 ARCH=ia64 O=/kisskb/build/powerpc-next_ia64-defconfig_ia64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux- /kisskb/src/mm/vmstat.c: In function 'sysctl_vm_numa_stat_handler': /kisskb/src/mm/vmstat.c:90:5: warning: 'oldval' 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/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/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2077:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1465:5: warning: 'page' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/fork.c:768:13: warning: 'task_struct_whitelist' defined but not used [-Wunused-function] /kisskb/src/net/ipv4/ip_output.c: In function '__ip_append_data': /kisskb/src/include/linux/skbuff.h:1406:6: warning: 'extra_uref' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/net/ipv4/ip_output.c:881:14: note: 'extra_uref' was declared here /kisskb/src/net/ipv4/fib_semantics.c: In function 'fib_check_nh_v4_gw': /kisskb/src/net/ipv4/fib_semantics.c:1027:12: warning: 'err' may be used uninitialized in this function [-Wuninitialized] No errors detected in 21387 functions.
