2023-08-09accel/ivpu: Rename sources to use generation based namesJacek Lawrynowicz
Given that VPU generation can be used by multiple platforms, driver should use VPU IP generation in names instead of a platform. Change naming for sources files. Use 37XX format, where: 3 - major VPU IP generation version 7 - minor VPU IP generation version XX - postfix indicating this is an architecture and not marketing name Signed-off-by: Jacek Lawrynowicz <jacek.lawrynowicz@linux.intel.com> Reviewed-by: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Signed-off-by: Stanislaw Gruszka <stanislaw.gruszka@linux.intel.com> Reviewed-by: Jeffrey Hugo <quic_jhugo@quicinc.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230731161258.2987564-2-stanislaw.gruszka@linux.intel.com

2023-07-05accel/ivpu: Clear specific interrupt status bits on C0Karol Wachowski
MTL C0 stepping fixed issue related to butrress interrupt status clearing, to clear an interrupt status it is required to write 1 to specific status bit field. This allows to execute read, modify and write routine. Writing 0 will not clear the interrupt and will cause interrupt storm.

Wait for AON bit in HOST_SS_CPR_RST_CLR to return 0 before starting VPUIP power up sequence, otherwise the VPU device may sporadically fail to boot. An error in power up sequence is propagated to the runtime power management - the device will be in an error state until the VPU driver is reloaded.

2023-06-08accel/ivpu: Do not trigger extra VPU reset if the VPU is idleAndrzej Kacprowski
Turning off the PLL and entering D0i3 will reset the VPU so an explicit IP reset is redundant. But if the VPU is active, it may interfere with PLL disabling and to avoid that, we have to issue an additional IP reset to silence the VPU before turning off the PLL.

2023-01-19accel/ivpu: Add Intel VPU MMU supportJacek Lawrynowicz
VPU Memory Management Unit is based on ARM MMU-600. It allows the creation of multiple virtual address spaces for the device and map noncontinuous host memory (there is no dedicated memory on the VPU). Address space is implemented as a struct ivpu_mmu_context, it has an ID, drm_mm allocator for VPU addresses and struct ivpu_mmu_pgtable that holds actual 3-level, 4KB page table. Context with ID 0 (global context) is created upon driver initialization and it's mainly used for mapping memory required to execute the firmware. Contexts with non-zero IDs are user contexts allocated each time the devices is open()-ed and they map command buffers and other workload-related memory. Workloads executing in a given contexts have access only to the memory mapped in this context. This patch is has two main files: - ivpu_mmu_context.c handles MMU page tables and memory mapping - ivpu_mmu.c implements a driver that programs the MMU device Co-developed-by: Karol Wachowski <karol.wachowski@linux.intel.com> Signed-off-by: Karol Wachowski <karol.wachowski@linux.intel.com> 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/20230117092723.60441-3-jacek.lawrynowicz@linux.intel.com
2023-01-19accel/ivpu: Introduce a new DRM driver for Intel VPUJacek Lawrynowicz
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
