This reverts commit 27c3e9452d552ea86369a94f23287a9675f2d7a1. Needed to restore the fbdev damage worker. There have been bug reports about locking order [1] and incorrectly takens branches.

accel: add dedicated minor for accelerator devices

2022-11-22T11:14:44Z

The accelerator devices are exposed to user-space using a dedicated major. In addition, they are represented in /dev with new, dedicated device char names: /dev/accel/accel*. This is done to make sure any user-space software that tries to open a graphic card won't open the accelerator device by mistake. The above implies that the minor numbering should be separated from the rest of the DRM devices. However, to avoid code duplication, we want the drm_minor structure to be able to represent the accelerator device. To achieve this, we add a new drm_minor* to drm_device that represents the accelerator device. This pointer is initialized for drivers that declare they handle compute accelerator, using a new driver feature flag called DRIVER_COMPUTE_ACCEL. It is important to note that this driver feature is mutually exclusive with DRIVER_RENDER. Devices that want to expose both graphics and compute device char files should be handled by two drivers that are connected using the auxiliary bus framework. In addition, we define a different IDR to handle the accelerators minors. This is done to make the minor's index be identical to the device index in /dev/. Any access to the IDR is done solely by functions in accel_drv.c, as the IDR is define as static. The DRM core functions call those functions in case they detect the minor's type is DRM_MINOR_ACCEL. We define a separate accel_open function (from drm_open) that the accel drivers should set as their open callback function. Both these functions eventually call the same drm_open_helper(), which had to be changed to be non-static so it can be called from accel_drv.c. accel_open() only partially duplicates drm_open as I removed some code from it that handles legacy devices. To help new drivers, I defined DEFINE_DRM_ACCEL_FOPS macro to easily set the required function operations pointers structure.

drivers/accel: define kconfig and register a new major

2022-11-22T11:13:51Z

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.

So a change to the UAPI header, but no functional change in the UAPI.

drm: Move nomodeset kernel parameter to drivers/video

2022-11-16T12:26:12Z

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 Reviewed-by: Javier Martinez Canillas Link: https://patchwork.freedesktop.org/patch/msgid/20221111133024.9897-2-tzimmermann@suse.de
