This can # result in contention of ATSD registers leading to soft lockups on some # threads, particularly when invalidating a large address range in # pnv_npu2_mn_invalidate_range(). # # At some threshold it becomes more efficient to flush the entire GPU # TLB for the given MM context (PID) than individually flushing each # address in the range. This patch will result in ranges greater than # 2MB being converted from 32+ ATSDs into a single ATSD which will flush # the TLB for the given PID on each GPU. # # Fixes: 1ab66d1fbada ("powerpc/powernv: Introduce address translation services for Nvlink2") # Cc: stable@vger.kernel.org # v4.12+ # Signed-off-by: Alistair Popple <alistair@popple.id.au> # Acked-by: Balbir Singh <bsingharora@gmail.com> # Tested-by: Balbir Singh <bsingharora@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < git log --format=%s --max-count=1 1e072bee33d09c62a975faab919a5be92d9538ab # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc 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:183:16: warning: 'old' 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:251:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:231:19: note: 'i' was declared here /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:340:21: note: 'pdeo' was declared here arch/powerpc/boot/walnut.dtb: Warning (pci_bridge): /plb/pci@ec000000: missing bus-range for PCI bridge arch/powerpc/boot/walnut.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' arch/powerpc/boot/ep405.dtb: Warning (pci_bridge): /plb/pci@ec000000: missing bus-range for PCI bridge arch/powerpc/boot/ep405.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' arch/powerpc/boot/hotfoot.dtb: Warning (pci_bridge): /plb/pci@ec000000: missing bus-range for PCI bridge arch/powerpc/boot/hotfoot.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' INFO: Uncompressed kernel (size 0x507774) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x507774) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x4f7100) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x507774) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x507774) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-4.17.0-rc1-g1e072be Created: Fri Apr 20 23:54:24 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2508694 Bytes = 2449.90 kB = 2.39 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.17.0-rc1-g1e072be Created: Fri Apr 20 23:54:24 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2535712 Bytes = 2476.28 kB = 2.42 MB Load Address: 00600000 Entry Point: 00601350 Image Name: Linux-4.17.0-rc1-g1e072be Created: Fri Apr 20 23:54:25 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2535805 Bytes = 2476.37 kB = 2.42 MB Load Address: 00600000 Entry Point: 00601534 Completed OK # rm -rf /kisskb/build/powerpc-fixes_ppc40x_defconfig_powerpc # Build took: 0:00:37.004556
