9f20c9f4 - accel: fix CONFIG_DRM dependencies

Fri, 27 Jan 2023 22:14:55 +0000

accel: fix CONFIG_DRM dependenciesAt the moment, accel drivers can be built-in even with CONFIG_DRM=m,but this causes a link failure:x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_dev_init':ivpu_drv.c:(.text+0x1535): undefined reference to `drmm_kmalloc'x86_64-linux-ld: ivpu_drv.c:(.text+0x1562): undefined reference to `drmm_kmalloc'x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_remove':ivpu_drv.c:(.text+0x1faa): undefined reference to `drm_dev_unregister'x86_64-linux-ld: drivers/accel/ivpu/ivpu_drv.o: in function `ivpu_probe':ivpu_drv.c:(.text+0x1fef): undefined reference to `__devm_drm_dev_alloc'The problem is that DRM_ACCEL is a 'bool' symbol, so driver thatonly depend on DRM_ACCEL but not also on DRM do not see the restrictionto =m configs.To ensure that each accel driver has an implied dependency on CONFIG_DRM,enclose the entire Kconfig file in an if/endif check.Fixes: 8bf4889762a8 ("drivers/accel: define kconfig and register a new major")Signed-off-by: Arnd Bergmann Reviewed-by: Stanislaw Gruszka Reviewed-by: Jeffrey Hugo Reviewed-by: Oded Gabbay Signed-off-by: Jacek Lawrynowicz Link: https://patchwork.freedesktop.org/patch/msgid/20230127221504.2522909-1-arnd@kernel.org(cherry picked from commit 3524c96a121952f214271622bb372661ced86101)Signed-off-by: Thomas Zimmermann List of files: /linux-6.15/drivers/accel/Kconfig

e65e175b - habanalabs: move driver to accel subsystem

Mon, 26 Dec 2022 21:05:00 +0000

habanalabs: move driver to accel subsystemNow that we have a subsystem for compute accelerators, move thehabanalabs driver to it.This patch only moves the files and fixes the Makefiles. Futurepatches will change the existing code to register to the accelsubsystem and expose the accel device char files instead of thehabanalabs device char files.Update the MAINTAINERS file to reflect this change.Signed-off-by: Oded Gabbay List of files: /linux-6.15/drivers/accel/Kconfig

35b13763 - accel/ivpu: Introduce a new DRM driver for Intel VPU

Tue, 17 Jan 2023 09:27:17 +0000

accel/ivpu: Introduce a new DRM driver for Intel VPUVPU stands for Versatile Processing Unit and it's a CPU-integratedinference accelerator for Computer Vision and Deep Learningapplications.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 componentsThis driver supports VPU IP v2.7 integrated into Intel Meteor Lakeclient 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 firmwareCo-developed-by: Krystian Pradzynski Signed-off-by: Krystian Pradzynski Signed-off-by: Jacek Lawrynowicz Reviewed-by: Oded Gabbay Reviewed-by: Jeffrey Hugo Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20230117092723.60441-2-jacek.lawrynowicz@linux.intel.com List of files: /linux-6.15/drivers/accel/Kconfig

8bf48897 - drivers/accel: define kconfig and register a new major

Mon, 31 Oct 2022 13:28:35 +0000

drivers/accel: define kconfig and register a new majorAdd a new Kconfig for the accel subsystem. The Kconfig currentlycontains only the basic CONFIG_DRM_ACCEL option that will be used todecide whether to compile the accel registration code. Therefore, thekconfig option is defined as bool.The accel code will be compiled as part of drm.ko and will be calleddirectly from the DRM core code. The reason we compile it as part ofdrm.ko and not as a separate module is because of cyclic dependencybetween drm.ko and the separate module (if it would have existed).This is due to the fact that DRM core code calls accel functions andvice-versa.The accelerator devices will be exposed to the user space with a new,dedicated major number - 261.The accel init function registers the new major number as a char deviceand create corresponding sysfs and debugfs root entries, similar towhat is done in DRM init function.I added a new header called drm_accel.h to include/drm/, that will holdthe prototypes of the drm_accel.c functions. In case CONFIG_DRM_ACCELis set to 'N', that header will contain empty inline implementations ofthose functions, to allow DRM core code to compile successfullywithout dependency on CONFIG_DRM_ACCEL.I Updated the MAINTAINERS file accordingly with the newly added folderand I have taken the liberty to appropriate the dri-devel mailing listand the dri-devel IRC channel for the accel subsystem.Signed-off-by: Oded Gabbay Reviewed-by: Greg Kroah-Hartman Reviewed-by: Jeffrey Hugo Reviewed-by: Dave Airlie Acked-by: Thomas Zimmermann Acked-by: Jacek Lawrynowicz Tested-by: Jacek Lawrynowicz Reviewed-by: Melissa Wen List of files: /linux-6.15/drivers/accel/Kconfig
