If devm_drm_of_get_bridge() can't find the connected bridge, it returns an ERR_PTR(-EPROBE_DEFER) to indicate that the probe should be deferred. But this path also prints an error message, which pollutes the kernel log since is printed on every probe deferral, i.e: $ dmesg | grep "failed to create panel bridge" | wc -l 38 Signed-off-by:

Komeda driver relies on the generic DRM atomic helper functions to handle commits. It only implements an atomic_commit_tail hook for the mode_config_helper_funcs and even that one is pretty close to the generic implementation with the exception of additional dma_fence signalling. What the generic helper framework doesn't do is waiting for the actual hardware to signal that the commit parameters have been written into the appropriate registers. As we signal CRTC events only on the irq handlers, we need to flush the configuration and wait for the hardware to respond. Add the Komeda specific implementation for atomic_commit_hw_done() that flushes and waits for flip done before calling drm_atomic_helper_commit_hw_done(). The fix was prompted by a patch from Carsten Haitzler where he was trying to solve the same issue but in a different way that I think can lead to wrong event signaling to userspace. Reported-by:

If something has already set up the DPU before the komeda driver comes up, it will fail to init because it was just writing to the SRST bit in the GCU control register and ignoring others. This resulted in TBU bringup stalling and init failing. By writing completely we also set the mode back to 0 (inactive) too and thus TBU bringup works. Signed-off-by:

The komeda driver doesn't come up with a visible text (FB) mode VT by default as it was missing legacy FB support. It's useful to have a working text VT on a system for debug and general usability, so enable it. You can always toggle CONFIG_FRAMEBUFFER_CONSOLE. Signed-off-by:

Since we no longer need to conform to the structure of the various DRM IRQ callbacks, we can streamline the code by consolidating the piecemeal functions and passing around our private data structure directly. We're also a platform device so should never see IRQ_NOTCONNECTED either. Furthermore we can also get rid of all the unnecesary read-modify-write operations, since on install we know we cleared the whole interrupt mask before enabling the debug IRQs, and thus on uninstall we're always clearing everything as well.

The Arm Juno board EDK2 port has provided an EFI GOP display via HDLCD0 for some time now, which works nicely as an early framebuffer. However, once the HDLCD driver probes and takes over the hardware, it should take over the logical framebuffer as well, otherwise the now-defunct GOP device hangs about and virtual console output inevitably disappears into the wrong place most of the time. We'll do this after binding the HDMI encoder, since that's the most likely thing to fail, and the EFI console is still better than nothing when that happens. However, the two HDLCD controllers on Juno are independent, and many users will still be using older firmware without any display support, so we'll only bother if we find that the HDLCD we're probing is already enabled. And if it is, then we'll also stop it, since otherwise the display can end up shifted if it's still scanning out while the rest of the registers are subsequently reconfigured. Signed-off-by:

DRM formats are defined to be little-endian, unless the DRM_FORMAT_BIG_ENDIAN flag is set. Hence when converting from one format to another, multi-byte pixel values loaded from memory must be converted from little-endian to host-endian. Conversely, multi-byte pixel values written to memory must be converted from host-endian to little-endian. Currently only drm_fb_xrgb8888_to_rgb332_line() includes endianness handling. Fix gud_xrgb8888_to_color() on big-endian platforms by adding the missing endianness handling. Signed-off-by:

DRM API requires the DRM's driver to be backed with the device that can be used for generic DMA operations. The VirtIO-GPU device can't perform DMA operations if it uses PCI transport because PCI device driver creates a virtual VirtIO-GPU device that isn't associated with the PCI. Use PCI's GPU device for the DRM's device instead of the VirtIO-GPU device and drop DMA-related hacks from the VirtIO-GPU driver. Signed-off-by:

Change the order of SHMEM initialization and reservation locking to make code cleaner and to prepare for transitioning of the common GEM SHMEM code to use the GEM's reservation lock instead of the shmem.page_lock. There is no need to lock reservation during allocation of the SHMEM pages because the lock is needed only to avoid racing with the async host-side allocation. Hence we can safely move the SHMEM initialization out of the reservation lock. Signed-off-by:
