2023-06-06 | accel/ivpu: ivpu_ipc needs GENERIC_ALLOCATOR | Randy Dunlap | 1 | -0/+1 | |
Drivers that use the gen_pool*() family of functions should select GENERIC_ALLOCATOR to prevent build errors like these: ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_free': include/linux/genalloc.h:172: undefined reference to `gen_pool_free_owner' ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_alloc_algo': include/linux/genalloc.h:138: undefined reference to `gen_pool_alloc_algo_owner' ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_free': include/linux/genalloc.h:172: undefined reference to `gen_pool_free_owner' ld: drivers/accel/ivpu/ivpu_ipc.o: in function `ivpu_ipc_init': drivers/accel/ivpu/ivpu_ipc.c:441: undefined reference to `devm_gen_pool_create' ld: drivers/accel/ivpu/ivpu_ipc.o: in function `gen_pool_add_virt': include/linux/genalloc.h:104: undefined reference to `gen_pool_add_owner' Fixes: 5d7422cfb498 ("accel/ivpu: Add IPC driver and JSM messages") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kernel test robot <lkp@intel.com> Link: https://lore.kernel.org/all/202305221206.1TaugDKP-lkp@intel.com/ Cc: Oded Gabbay <ogabbay@kernel.org> Cc: dri-devel@lists.freedesktop.org Cc: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Cc: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Cc: Andrzej Kacprowski <andrzej.kacprowski@linux.intel.com> Cc: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Cc: Jeffrey Hugo <quic_jhugo@quicinc.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230526044519.13441-1-rdunlap@infradead.org | |||||
2023-01-19 | accel/ivpu: Introduce a new DRM driver for Intel VPU | Jacek Lawrynowicz | 1 | -0/+15 | |
VPU stands for Versatile Processing Unit and it's a CPU-integrated inference accelerator for Computer Vision and Deep Learning applications. The VPU device consist of following components: - Buttress - provides CPU to VPU integration, interrupt, frequency and power management. - Memory Management Unit (based on ARM MMU-600) - translates VPU to host DMA addresses, isolates user workloads. - RISC based microcontroller - executes firmware that provides job execution API for the kernel-mode driver - Neural Compute Subsystem (NCS) - does the actual work, provides Compute and Copy engines. - Network on Chip (NoC) - network fabric connecting all the components This driver supports VPU IP v2.7 integrated into Intel Meteor Lake client CPUs (14th generation). Module sources are at drivers/accel/ivpu and module name is "intel_vpu.ko". This patch includes only very besic functionality: - module, PCI device and IRQ initialization - register definitions and low level register manipulation functions - SET/GET_PARAM ioctls - power up without firmware Co-developed-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Krystian Pradzynski <krystian.pradzynski@linux.intel.com> Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Oded Gabbay <ogabbay@kernel.org> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-2-jacek.lawrynowicz@linux.intel.com |
