2023-03-14drm/fbdev-dma: Implement fbdev emulation for GEM DMA helpersThomas Zimmermann1-0/+1
Implement fbdev emulation that is optimized for drivers that use DMA helpers. The buffers may no tbe moveable, may not require damage handling and have to be located in system memory. This allows fbdev emulation to operate directly on the buffer and mmap it to userspace. Besides those constraints, the emulation works like in the generic code. As an internal DRM client provides, it receives hotplug, restore and unregister events. The DRM client is independent from the fbdev probing, which runs on the first successful hotplug event. The emulation is part of the DMA helper module and not build unless DMA helpers and fbdev emulation has been configured. Tested with vc4.

Suballocating a buffer object is something that is not driver-specific and useful for many drivers. Use a slightly modified version of amdgpu_sa.c v2: - Style cleanups. - Added / Modified documentation. - Use u64 for the sizes and offset. The code dates back to 2012 and using unsigned int will probably soon come back to bite us. We can consider size_t as well for better 32-bit efficiency. - Add and document gfp, intr and align arguments to drm_suballoc_new(). - Use drm_printer for debug output. v3: - Remove stale author info (Christian König) v4: - Avoid 64-bit integer divisions (kernel test robot <lkp@intel.com>) - Use size_t rather than u64 for the managed range.

2022-11-22drivers/accel: define kconfig and register a new majorOded Gabbay1-0/+1
Add a new Kconfig for the accel subsystem. The Kconfig currently contains only the basic CONFIG_DRM_ACCEL option that will be used to decide whether to compile the accel registration code. Therefore, the kconfig option is defined as bool. The accel code will be compiled as part of drm.ko and will be called directly from the DRM core code. The reason we compile it as part of drm.ko and not as a separate module is because of cyclic dependency between drm.ko and the separate module (if it would have existed). This is due to the fact that DRM core code calls accel functions and vice-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 device and create corresponding sysfs and debugfs root entries, similar to what is done in DRM init function. I added a new header called drm_accel.h to include/drm/, that will hold the prototypes of the drm_accel.c functions. In case CONFIG_DRM_ACCEL is set to 'N', that header will contain empty inline implementations of those functions, to allow DRM core code to compile successfully without dependency on CONFIG_DRM_ACCEL. I Updated the MAINTAINERS file accordingly with the newly added folder and I have taken the liberty to appropriate the dri-devel mailing list and the dri-devel IRC channel for the accel subsystem.

2022-11-16drm: Move nomodeset kernel parameter to drivers/videoThomas Zimmermann1-1/+0
Move the nomodeset kernel parameter to drivers/video to make it available to non-DRM drivers. Adapt the interface, but keep the DRM interface drm_firmware_drivers_only() to avoid churn within DRM. The function should later be inlined into callers. The parameter disables any DRM graphics driver that would replace a driver for firmware-provided scanout buffers. It is an option to easily fallback to basic graphics output if the hardware's native driver is broken. Moving it to a more prominent location wil make it available to fbdev as well. v2: * clarify the meaning of the nomodeset parameter (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221111133024.9897-2-tzimmermann@suse.de

This patch is compile-time tested building a x86_64 kernel with `make allyesconfig && make drivers/gpu/drm`.

2022-06-09drm: Add support for the LogiCVC display controllerPaul Kocialkowski1-0/+1
Introduces a driver for the LogiCVC display controller, a programmable logic controller optimized for use in Xilinx Zynq-7000 SoCs and other Xilinx FPGAs. The controller is mostly configured at logic synthesis time so only a subset of configuration is left for the driver to handle. The following features are implemented and tested: - LVDS 4-bit interface; - RGB565 pixel formats; - Multiple layers and hardware composition; - Layer-wide alpha mode; The following features are implemented but untested: - Other RGB pixel formats; - Layer framebuffer configuration for version 4; - Lowest-layer used as background color; - Per-pixel alpha mode. The following features are not implemented: - YUV pixel formats; - DVI, LVDS 3-bit, ITU656 and camera link interfaces; - External parallel input for layer; - Color-keying; - LUT-based alpha modes. Additional implementation-specific notes: - Panels are only enabled after the first page flip to avoid flashing a white screen. - Depth used in context of the LogiCVC driver only counts color components to match the definition of the synthesis parameters. Support is implemented for both version 3 and 4 of the controller. With version 3, framebuffers are stored in a dedicated contiguous memory area, with a base address hardcoded for each layer. This requires using a dedicated CMA pool registered at the base address and tweaking a few offset-related registers to try to use any buffer allocated from the pool. This is done on a best-effort basis to have the hardware cope with the DRM framebuffer allocation model and there is no guarantee that each buffer allocated by GEM CMA can be used for any layer. In particular, buffers allocated below the base address for a layer are guaranteed not to be configurable for that layer. See the implementation of logicvc_layer_buffer_find_setup for specifics. Version 4 allows configuring each buffer address directly, which guarantees that any buffer can be configured.

2021-10-14drm: Add privacy-screen class (v4)Hans de Goede1-0/+1
On some new laptops the LCD panel has a builtin electronic privacy-screen. We want to export this functionality as a property on the drm connector object. But often this functionality is not exposed on the GPU but on some other (ACPI) device. This commit adds a privacy-screen class allowing the driver for these other devices to register themselves as a privacy-screen provider; and allowing the drm/kms code to get a privacy-screen provider associated with a specific GPU/connector combo. Changes in v2: - Make CONFIG_DRM_PRIVACY_SCREEN a bool which controls if the drm_privacy code gets built as part of the main drm module rather then making it a tristate which builds its own module. - Add a #if IS_ENABLED(CONFIG_DRM_PRIVACY_SCREEN) check to drm_privacy_screen_consumer.h and define stubs when the check fails. Together these 2 changes fix several dependency issues. - Remove module related code now that this is part of the main drm.ko - Use drm_class as class for the privacy-screen devices instead of adding a separate class for this Changes in v3: - Make the static inline drm_privacy_screen_get_state() stub set sw_state and hw_state to PRIVACY_SCREEN_DISABLED to squelch an uninitialized variable warning when CONFIG_DRM_PRIVICAY_SCREEN is not set Changes in v4: - Make drm_privacy_screen_set_sw_state() skip calling out to the hw if hw_state == new_sw_state Reviewed-by: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Lyude Paul <lyude@redhat.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211005202322.700909-3-hdegoede@redhat.com
