This fixes a use-after-free crash during rmmod. The DRM encoder is embedded inside the larger rockchip_hdmi, which is allocated with the component. The component memory gets freed before the main drm device is destroyed. Fix it by running encoder cleanup before tearing down its container. Signed-off-by:

Consolidate all handling of CONFIG_DRM_FBDEV_LEAK_PHYS_SMEM by making the module parameter optional in drm_fb_helper.c. Without the config option, modules can set smem_start in struct fb_info for internal usage, but not export if to userspace. The address can only be exported by enabling the option and setting the module parameter. Also update the comment. Signed-off-by:

Remove the flag prefer_shadow_fbdev from struct drm_mode_config. Drivers set this flag to enable shadow buffering in the generic fbdev emulation. Such shadow buffering is now mandatory, so the flag is unused. Signed-off-by:

Thomas Zimmermann authored
Remove all codepaths that implement fbdev output directly on GEM buffers. Always allocate a shadow buffer in system memory and set up deferred I/O for mmap. The fbdev code that operated directly on GEM buffers was used by drivers based on GEM DMA helpers. Those drivers have been migrated to use fbdev-dma, a dedicated fbdev emulation for DMA memory. All remaining users of fbdev-generic require shadow buffering. Memory management of the remaining callers uses TTM, GEM SHMEM helpers or a variant of GEM DMA helpers that is incompatible with fbdev-dma. Therefore remove the unused codepaths from fbdev-generic and simplify the code. Using a shadow buffer with deferred I/O is probably the best case for most remaining callers. Some of the TTM-based drivers might benefit from a dedicated fbdev emulation that operates directly on the driver's video memory. Signed-off-by:

Merge tag 'drm-habanalabs-next-2023-03-20' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next This tag contains habanalabs driver and accel changes for v6.4: - uAPI changes: - Add opcodes to the CS ioctl to allow user to stall/resume specific engines inside Gaudi2. This is to allow the user to perform power testing/measurements when training different topologies. - Expose in the INFO ioctl the amount of device memory that the driver and f/w reserve for themselves. - Expose in the INFO ioctl a bit-mask of the available rotator engines in Gaudi2. This is to align with other engines that are already exposed. - Expose in the INFO ioctl the register's address of the f/w that should be used to trigger interrupts from within the user's code running in the compute engines. - Add a critical-event bit in the eventfd bitmask so the user will know the event that was received was critical, and a reset will now occur - Expose in the INFO ioctl two new opcodes to fetch information on h/w and f/w events. The events recorded are the events that were reported in the eventfd. - New features and improvements: - Add a dedicated interrupt ID in MSI-X in the device to the notification of an unexpected user-related event in Gaudi2. Handle it in the driver by reporting this event. - Allow the user to fetch the device memory current usage even when the device is undergoing compute-reset (a reset type that only clears the compute engines). - Enable graceful reset mechanism for compute-reset. This will give the user a few seconds before the device is reset. For example, the user can, during that time, perform certain device operations (dump data for debug) or close the device in an orderly fashion. - Align the decoder with the rest of the engines in regard to notification to the user about interrupts and in regard to performing graceful reset when needed (instead of immediate reset). - Add support for assert interrupt from the TPC engine. - Get the reset type that is necessary to perform per event from the auto-generated irq_map array. - Print the specific reason why a device is still in use when notifying to the user about it (after the user closed the device's FD). - Move to threaded IRQ when handling interrupts of workload completions. - Firmware related fixes: - Fix RAZWI event handler to match newest f/w version. - Read error cause register in dma core events because the f/w doesn't do that. - Increase maximum time to wait for completion of Gaudi2 reset due to f/w bug. - Align to the latest firmware specs. - Enforce the release order of the compute device and dma-buf. i.e increment the device file refcount for any dma-buf that was exported for that device. This will make sure the compute device release function won't be called until the user closes all the FDs of the relevant dma-bufs. Without this change, closing the device's FD before/without closing the dma-buf's FD would always lead to hard-reset of the device. - Fix a link in the drm documentation to correctly point to the accel section. - Compilation warnings cleanups - Misc bug fixes and code cleanups Signed-off-by:
