In addition to that the GPUs have 6 NVLinks # which are connected to other GPUs and the POWER9 CPU. POWER9 chips # have a special unit on a die called an NPU which is an NVLink2 host bus # adapter with p2p connections to 2 to 3 GPUs, 3 or 2 NVLinks to each. # These systems also support ATS (address translation services) which is # a part of the NVLink2 protocol. Such GPUs also share on-board RAM # (16GB or 32GB) to the system via the same NVLink2 so a CPU has # cache-coherent access to a GPU RAM. # # This exports GPU RAM to the userspace as a new VFIO device region. This # preregisters the new memory as device memory as it might be used for DMA. # This inserts pfns from the fault handler as the GPU memory is not onlined # until the vendor driver is loaded and trained the NVLinks so doing this # earlier causes low level errors which we fence in the firmware so # it does not hurt the host system but still better be avoided; for the same # reason this does not map GPU RAM into the host kernel (usual thing for # emulated access otherwise). # # This exports an ATSD (Address Translation Shootdown) register of NPU which # allows TLB invalidations inside GPU for an operating system. The register # conveniently occupies a single 64k page. It is also presented to # the userspace as a new VFIO device region. One NPU has 8 ATSD registers, # each of them can be used for TLB invalidation in a GPU linked to this NPU. # This allocates one ATSD register per an NVLink bridge allowing passing # up to 6 registers. Due to the host firmware bug (just recently fixed), # only 1 ATSD register per NPU was actually advertised to the host system # so this passes that alone register via the first NVLink bridge device in # the group which is still enough as QEMU collects them all back and # presents to the guest via vPHB to mimic the emulated NPU PHB on the host. # # In order to provide the userspace with the information about GPU-to-NVLink # connections, this exports an additional capability called "tgt" # (which is an abbreviated host system bus address). The "tgt" property # tells the GPU its own system address and allows the guest driver to # conglomerate the routing information so each GPU knows how to get directly # to the other GPUs. # # For ATS to work, the nest MMU (an NVIDIA block in a P9 CPU) needs to # know LPID (a logical partition ID or a KVM guest hardware ID in other # words) and PID (a memory context ID of a userspace process, not to be # confused with a linux pid). This assigns a GPU to LPID in the NPU and # this is why this adds a listener for KVM on an IOMMU group. A PID comes # via NVLink from a GPU and NPU uses a PID wildcard to pass it through. # # This requires coherent memory and ATSD to be available on the host as # the GPU vendor only supports configurations with both features enabled # and other configurations are known not to work. Because of this and # because of the ways the features are advertised to the host system # (which is a device tree with very platform specific properties), # this requires enabled POWERNV platform. # # The V100 GPUs do not advertise any of these capabilities via the config # space and there are more than just one device ID so this relies on # the platform to tell whether these GPUs have special abilities such as # NVLinks. # # Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> # Acked-by: Alex Williamson <alex.williamson@redhat.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux-ld --version # < git log --format=%s --max-count=1 7f92891778dff62303c070ac81de7b7d80de331a # < make -s -j 48 ARCH=m68k O=/kisskb/build/powerpc-next_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- defconfig # make -s -j 48 ARCH=m68k O=/kisskb/build/powerpc-next_m68k-defconfig_m68k CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/m68k-linux/bin/m68k-linux- <stdin>:1239:2: warning: #warning syscall seccomp not implemented [-Wcpp] <stdin>:1317:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp] <stdin>:1320:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp] <stdin>:1323:2: warning: #warning syscall pkey_free not implemented [-Wcpp] <stdin>:1332:2: warning: #warning syscall io_pgetevents not implemented [-Wcpp] <stdin>:1335:2: warning: #warning syscall rseq not implemented [-Wcpp] /kisskb/src/arch/m68k/kernel/signal.c: In function 'mangle_kernel_stack': /kisskb/src/arch/m68k/kernel/signal.c:654:3: warning: variable length array 'buf' is used [-Wvla] /kisskb/src/arch/m68k/atari/config.c: In function 'atari_switches_setup': /kisskb/src/arch/m68k/atari/config.c:151:2: warning: variable length array 'switches' is used [-Wvla] /kisskb/src/arch/m68k/mvme147/config.c: In function 'mvme147_hwclk': /kisskb/src/arch/m68k/mvme147/config.c:150:2: warning: #warning check me!
