2022-11-22accel: add dedicated minor for accelerator devicesOded Gabbay
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.

2022-11-22drivers/accel: define kconfig and register a new majorOded Gabbay
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.

2022-11-16tracing/ring-buffer: Have polling block on watermarkSteven Rostedt (Google)
Currently the way polling works on the ring buffer is broken. It will return immediately if there's any data in the ring buffer whereas a read will block until the watermark (defined by the tracefs buffer_percent file) is hit. That is, a select() or poll() will return as if there's data available, but then the following read will block. This is broken for the way select()s and poll()s are supposed to work. Have the polling on the ring buffer also block the same way reads and splice does on the ring buffer.

sk->sk_user_data has multiple users, which are not compatible with each other. Writers must synchronize by grabbing the sk->sk_callback_lock. l2tp currently fails to grab the lock when modifying the underlying tunnel socket fields. Fix it by adding appropriate locking.

2022-11-16fbdev: Add support for the nomodeset kernel parameterThomas Zimmermann
Support the kernel's nomodeset parameter for all PCI-based fbdev drivers that use aperture helpers to remove other, hardware-agnostic graphics drivers. The parameter is a simple way of using the firmware-provided scanout buffer if the hardware's native driver is broken. The same effect could be achieved with per-driver options, but the importance of the graphics output for many users makes a single, unified approach worthwhile. With nomodeset specified, the fbdev driver module will not load. This unifies behavior with similar DRM drivers. In DRM helpers, modules first check the nomodeset parameter before registering the PCI driver. As fbdev has no such module helpers, we have to modify each driver individually. The name 'nomodeset' is slightly misleading, but has been chosen for historical reasons. Several drivers implemented it before it became a general option for DRM. So keeping the existing name was preferred over introducing a new one. v2: * print a warning if a driver does not init (Helge) * wrap video_firmware_drivers_only() in helper Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20221111133024.9897-3-tzimmermann@suse.de
2022-11-16drm: Move nomodeset kernel parameter to drivers/videoThomas Zimmermann
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

2022-11-16drm/fb-helper: Schedule deferred-I/O worker after writing to framebufferThomas Zimmermann
Schedule the deferred-I/O worker instead of the damage worker after writing to the fbdev framebuffer. The deferred-I/O worker then performs the dirty-fb update. The fbdev emulation will initialize deferred I/O for all drivers that require damage updates. It is therefore a valid assumption that the deferred-I/O worker is present. It would be possible to perform the damage handling directly from within the write operation. But doing this could increase the overhead of the write or interfere with a concurrently scheduled deferred-I/O worker. Instead, scheduling the deferred-I/O worker with its regular delay of 50 ms removes load off the write operation and allows the deferred-I/O worker to handle multiple write operations that arrived during the delay time window. v3: * remove unused variable (lkp) v2: * keep drm_fb_helper_damage() (Daniel) * use fb_deferred_io_schedule_flush() (Daniel) * clarify comments (Daniel) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20221115115819.23088-6-tzimmermann@suse.de

2022-11-15drm/amdgpu: revert "implement tdr advanced mode"Christian König
This reverts commit e6c6338f393b74ac0b303d567bb918b44ae7ad75. This feature basically re-submits one job after another to figure out which one was the one causing a hang. This is obviously incompatible with gang-submit which requires that multiple jobs run at the same time. It's also absolutely not helpful to crash the hardware multiple times if a clean recovery is desired. For testing and debugging environments we should rather disable recovery alltogether to be able to inspect the state with a hw debugger. Additional to that the sw implementation is clearly buggy and causes reference count issues for the hardware fence.
