* drm/arm/hdlcd: use new debugfs device-centered functionsMaíra Canal2023-01-061-15/+9
| | | | | | | | | | | | | Replace the use of drm_debugfs_create_files() with the new drm_debugfs_add_files() function, which center the debugfs files management on the drm_device instead of drm_minor. Moreover, remove the debugfs_init hook and add the debugfs files directly on hdlcd_drm_bind(), before drm_dev_register().

* drm/komeda: Fix handling of atomic commits in the atomic_commit_tail hookLiviu Dudau2022-07-223-3/+24
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* drm/arm/hdlcd: Take over EFI framebuffer properlyRobin Murphy2022-07-221-0/+10
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In komeda_plane_add(), komeda_get_layer_fourcc_list() is assigned to formats and used in drm_universal_plane_init(). drm_universal_plane_init() passes formats to __drm_universal_plane_init(). __drm_universal_plane_init() further passes formats to memcpy() as src parameter, which could lead to an undefined behavior bug on failure of komeda_get_layer_fourcc_list(). Fix this bug by adding a check of formats. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_DRM_KOMEDA=m show no new warnings, and our static analyzer no longer warns about this code.
