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-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 1e072bee33d09c62a975faab919a5be92d9538ab # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- allmodconfig # Added to kconfig CONFIG_CPU_LITTLE_ENDIAN=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n \| make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_allmodconfig+ppc64le_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/drivers/ata/ahci_qoriq.c: In function 'ahci_qoriq_hardreset': /kisskb/src/arch/powerpc/include/asm/io.h:160:2: warning: 'px_is' may be used uninitialized in this function [-Wmaybe-uninitialized] __asm__ __volatile__("sync;"#insn"%U0%X0 %1,%0" \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:14: note: 'px_is' was declared here u32 px_cmd, px_is, px_val; ^ In file included from /kisskb/src/include/linux/io.h:25:0, from /kisskb/src/include/linux/of_address.h:7, from /kisskb/src/drivers/ata/ahci_qoriq.c:18: /kisskb/src/arch/powerpc/include/asm/io.h:160:2: warning: 'px_cmd' may be used uninitialized in this function [-Wmaybe-uninitialized] __asm__ __volatile__("sync;"#insn"%U0%X0 %1,%0" \ ^ /kisskb/src/drivers/ata/ahci_qoriq.c:86:6: note: 'px_cmd' was declared here u32 px_cmd, px_is, px_val; ^ WARNING: vmlinux.o(.text+0x3664): Section mismatch in reference from the variable __boot_from_prom to the function .init.text:prom_init() The function __boot_from_prom() references the function __init prom_init().
